Description

  The present invention relates to a casing with a light emitting function capable of floating light of a desired lighting pattern on a surface layer.

  The inventor of the present application has previously developed a laminate with a light emitting function capable of causing light of a desired lighting pattern such as letters and designs to appear on a wooden surface layer (Patent Document 1). The laminated body with a light emitting function described in Patent Document 1 is shown in FIGS. 17 and 18, respectively. FIGS. 17 and 18 illustrate a door 800 as an example of a laminate with a light emitting function. FIG. 17 is a plan view of the door 800 and FIG. 18 is an exploded perspective view of the door 800.

  As shown in FIG. 17A, the door 800 includes a wooden layer 802 on the surface of the door, and a light source is disposed on the opposite back side. When the light source is turned off, the light source cannot be visually recognized from the front side of the door 800, and is not different from a general wood layer door. On the other hand, when the light source is energized, a light lighting pattern 801 such as letters and symbols appears on the surface of the door at a desired timing as shown in FIG. That is, the light from the light source is transmitted to the wood layer only when the power is turned on while the surface of the door is made a normal wood layer when the light source is not energized. As a result, the lighting pattern 801 emerges on the surface of the door so as to make the wood layer 802 stand out. A door where a light pattern suddenly appears can be a highly interesting door with a lot of surprises.

  As shown in FIG. 18, the door 800 is configured by laminating members having substantially the same size. The door 800 has a support 804 having a light source 803 in which a plurality of light emitting elements 811 are arranged in a dot matrix, a sheet layer 805 having an opening 809 corresponding to the arrangement region of the light source 803, and further prevents the member from warping. The reinforcing layer 806, the paper layer 807 that reduces the directivity of the light source, and the wood layer 808 that displays the lighting pattern 801 are stacked in this order. Light emitted from the light source 803 is transmitted through the opening 809 in the order of the reinforcing layer 806 and the paper layer 807, and finally projects a lighting pattern 801 on the surface of the wood layer 808 as shown in FIG. .

  Such a laminate with a light emitting function can also be applied to structures other than doors. For example, FIG. 19 shows a perspective view of a housing using a laminate. 20 is a cross-sectional view taken along line XX-XX ′ of FIG. A housing 900 in FIGS. 19 and 20 includes a housing body 901 that opens in one direction, and a stacked body 902 with a light emitting function that is fixed in a posture to close the opening of the housing body 901. The laminated body 902 with the light emitting function is connected so that the outer shape thereof substantially matches the outer periphery of the opening. This laminated body 902 with a light emitting function has the same structure as the above-described door, that is, a support body 804 including a light source 803, a sheet layer 805, a reinforcing layer 806, a paper layer 807, and a wood layer 808 are laminated in this order. The surface 902a of the wood layer 808 is used as a light viewing surface. When the light source 803 is energized, a predetermined lighting pattern 911 emerges on the viewing surface 902a of the wood layer 808. This casing 900 is movable, and can be conveniently used because it can be visually recognized around the sign of a significant light by installing it at a desired location.

  As shown in FIG. 19, the entire display surface 902 a is a single plate so that the display body looks like a wooden block when viewed from the front. By configuring the entire viewing surface 902a with a single plate, the connection site between the stacked body 902 and the housing body 901 can be made inconspicuous from the front. However, the display body 900 of FIGS. 19 and 20 has a problem that light from the light source 803 leaks not only from the viewing surface 902a of the stacked body 902 but also from the side surface 902b constituting the thickness when the light source is energized. It was. This is because light emitted from the light emitting element 811 of the light source 803 is reflected or diffused as shown in FIG. 20, and light leaks not only from the viewing surface 902a side but also from the side surface 902b side. Then, as shown in FIG. 19, since the leakage light also emits light around the viewing surface 902a, there is a problem that the light emission is diffused and the appearance is deteriorated. In particular, in the configuration in which the light emission is raised on the wood layer, it is not conscious of the lighting pattern when the light is turned off, and only the desired lighting pattern can be displayed on the surface of the wood layer when the light is turned on. Such effects diminish when leaks are viewed. In particular, when light is leaking from the side that is not supposed to emit light, when viewed from the side, not only the sign's intention is not transmitted, but the scattered light is simply seen and the appearance is extremely poor. Become. Further, the contrast between the viewing surface 902a and its surroundings is lowered on the front side, and the lighting pattern 911 formed on the viewing surface 902a has a problem of poor visibility.

  In order to avoid this problem, it is also conceivable that the light emitting element 811 is sufficiently separated from the side surface 902b of the stacked body 902, that is, the light emitting element 811 is disposed near the center of the viewing surface 902a. In this case, since the light source 803 is physically separated from the side surface 902b, the leakage light in the outer peripheral direction can be reduced to some extent, but still a non-negligible amount of leakage light is emitted. It does n’t come. In addition, with this method, the arrangement area of the light emitting elements 811 is limited, and thus the area where the lighting pattern 911 can be displayed is reduced to the center of the viewing surface 902a, and the corners of the viewing surface 902a cannot be used effectively. There were also drawbacks.

  Further, the housing 900 in FIG. 20 fixes the laminate 902 and the housing body 901 with an adhesive 913. In the display body 900 of FIG. 20, the end surface 912 on the opening side of the housing body 901 is attached to the back surface of the reinforcing layer 806 of the stacked body 902 via the adhesive 913 in the entire peripheral area of the opening edge. Therefore, in order to improve the adhesion between the back surface of the reinforcing layer 806 and the end surface 912 of the housing 901, the joint surfaces are formed horizontally and the adhesive 913 is applied substantially evenly. It becomes important.

  However, it is not practical to obtain such accuracy due to design tolerances and manufacturing variations. That is, in order to obtain the accuracy of adhering the laminated body 902 and the casing main body 901 in a parallel posture while keeping the coating thickness of the adhesive 913 constant, in either manual operation or automation However, the manufacturing cost is extremely increased and the manufacturing yield is reduced, and the yield is also reduced. In addition, if the bonding posture of the stacked body 902 or the casing body 901 is inclined even a little, an unintended gap is generated in any of the bonding regions. Further, when the adhesive 913 is unevenly distributed, a gap is generated between the members in a region where the coating amount is thick. When the gap is formed in this way, the above-described light leakage occurs. In particular, the housing 900 of FIGS. 19 and 20 has a wide adhesion region of a member made of an adhesive, and thus it is difficult to uniformly apply the adhesive 913 over the entire periphery of the housing body 901. The surplus of the adhesive 913 leaks to the outer surface of the casing 900 and causes burrs, which causes a problem of reducing the design.

  The present invention has been made to solve the conventional problems. That is, the main object of the present invention is to effectively prevent light leakage while suppressing the manufacturing cost, and to neatly light a desired light pattern on the surface of the wood layer and improve the visibility, and a housing with a light emitting function. It is in providing the manufacturing method.

  A housing with a light emitting function capable of displaying a desired lighting pattern on the surface of a wood layer, and a light display laminate that substantially closes the housing body 20 opened in at least one direction and the opening 21 of the housing body 20 1. The housing body 20 includes an inner wall surface 23 configured on the inner side of the opening, an outer surface 22 configured on the outer side, and an end surface 26 that configures the thickness of the housing body 20 at the opening end. The optical display laminate 1 is formed by laminating a base 9 including a light source unit 11 in which a plurality of light emitting elements 10 are arranged and a wood layer 12 covering the light source unit 11. And in the opening part 21 of the housing body 20, the inner wall surface 23 intersects at least a part of the optical display laminate 1 from the opening end part to the inner surface at a substantially right angle.

  The housing with the light emitting function has a structure in which the inner wall surface 23 and at least a part of the light display laminate 1 intersect at substantially right angles in the opening 21 of the housing body 20, so that light emitted from the light source unit 11 is emitted. Can be prevented from leaking out from the side surface 2. The housing with a light emitting function that can reduce the leakage light from the side direction can increase the contrast between the main surface area where the light pattern is to be exposed and the outer peripheral area of the non-display area. Can be increased.

In the case with the light emitting function, the inner wall surface 23 of the case body 20 can fix at least a part of the side surface 2 constituting the thickness of the optical display laminate 1. As a result, the housing main body that covers the side surface of the light source unit prevents the light from traveling in the lateral direction, so that it is possible to effectively prevent light from leaking from the outer surface of the housing main body.
The optical display laminate 1 has a flange portion 14 protruding outward from at least a part of the side surface 2. Further, the housing with a light emitting function has a wood grain pattern in which the outer surface 22 of the housing body 20 is substantially continuous, and the shape of the flange portion 14 of the optical display laminate 1 is formed on the inner wall surface 23 of the housing body 20. A recess 25 is formed along the line. The flange portion 14 is fitted in the recess 25. The connection structure in which the flange portion 14 of the optical display laminate 1 is fitted into the recess 25 of the housing main body 20 can easily maintain the casing main body 20 and the optical display laminate 1 in a predetermined posture.
The other housing with a light emitting function is a housing with a light emitting function capable of displaying a desired lighting pattern on the surface of the wood layer, and the housing body 20 opened in at least one direction, The optical display laminate 1 that substantially closes the opening 21 is provided. The housing body 20 includes an inner wall surface 23 that is formed inside the opening, an outer surface 22 that is formed outside, and an opening end. The optical display laminate 1 includes a base 9 including a light source unit 11 in which a plurality of light emitting elements 10 are arranged, and the light source unit 11. In the opening 21 of the housing body 20, the inner wall surface 23 intersects at least a part of the optical display laminate 1 from the opening end to the inner surface at a substantially right angle. An inner wall surface 23 of the housing body 20 is the optical display laminate. Securing at least a portion of the side surface 2 constituting one thickness.
In the case with the light emitting function, the wood layer 212 covers the end surface 226 of the case body 220, and the outer peripheral surface of the wood layer 212 is substantially flush with the outer surface 222 of the case body 220. And Accordingly, the outer surface from the optical display laminate 201 to the housing main body 220 can be configured as a continuous surface of the wood layer while avoiding the exposure of the end surface of the housing main body 220, thereby improving the design.
The thickness of the housing body 220 is configured so that the inner wall surface 223 is formed in a stepped shape at the opening end portion than the back side of the opening portion 21, and at least a part of the side surface 202 of the optical display laminate 201 is The inner wall surface 223 can be configured to fit into a stepped shape. Thereby, since the connection part of the optical display laminated body 201 and the housing | casing main body 220 can be made into a level | step difference and a contact area can be earned, both can be fixed more stably.
Still another case with a light emitting function is a case with a light emitting function capable of displaying a desired lighting pattern on the surface of the wood layer, and the case main body 20 opened in at least one direction, The optical display laminate 1 that substantially closes the opening 21 is provided. The housing body 20 includes an inner wall surface 23 that is formed inside the opening, an outer surface 22 that is formed outside, and an opening end. The optical display laminate 1 includes a base 9 including a light source unit 11 in which a plurality of light emitting elements 10 are arranged, and the light source unit 11. In the opening 21 of the housing body 20, the inner wall surface 23 intersects at least a part of the optical display laminate 1 from the opening end to the inner surface at a substantially right angle. An inner wall surface 23 of the housing body 20 is connected to the optical display product. Securing at least a portion of the side surface 2 constituting the thickness of the body 1.
Further, the housing with a light emitting function has a joint surface 27 formed from the outer corner to the inner corner at each corner of the housing body 20 formed in a frame shape. The adjacent surfaces of the housing body 20 are in contact with each other at a substantially right angle through the joint surface 27. Since the housing with a light emitting function having the joint surface 27 can easily assemble the box body 20 into a frame shape, the yield can be improved and the cost can be suppressed.

  Furthermore, in the housing with a light emitting function of the present invention, the end surface 26 of the housing body 20 is exposed in plan view from the viewing direction of the lighting pattern, and the outer periphery of the optical display laminate 1 is It is included in the end face 26. The optical display laminate 1 can be firmly fixed to the casing body 20 by being included in the end face 26 of the casing body 20. Further, the optical display laminate 1 can be reinforced with the housing body 20.

  The housing with a light emitting function has a flange portion 14 in which the optical display laminate 1 protrudes outward from at least a part of the side surface 2, and the flange portion 14 is connected to the inner wall surface 23 of the housing body 20. It is characterized by that. The case with a light emitting function that connects the optical display laminate 1 and the case main body 20 with the flange portion 14 is a case where a gap is generated between the side surface 2 of the optical display laminate 1 and the inner wall surface 23 of the case main body 20. Even if it exists, since this clearance gap can be obstruct | occluded with the flange part 14, it can prevent that the light of the light source part 11 leaks from the side surface 2 side of the optical display laminated body 1. FIG.

  The optical display laminate 1 has an intervening layer 13 between the base 9 and the wood layer 12. The intervening layer 13 includes at least a light diffusion layer 16 that adjusts the directivity of light from the light source unit 11 and a reinforcing layer 17 that reinforces the light diffusion layer 16. Thereby, it is possible to avoid exposing the arrangement pattern of the light emitting elements while improving the viewing angle of the light from the light source unit 11.

  Further, the housing with a light emitting function may be provided with a light scattering layer 24 on the outer surface 22 of the housing body 20. As a result, it is possible to prevent the lighting pattern of the light and external illumination light from being reflected on the surface of the housing body. As a result, the light / dark ratio in the display area and the non-display area of the lighting pattern is increased to improve the visibility of the lighting pattern. be able to.

  Further, according to the present invention, a method of manufacturing a casing with a light emitting function capable of displaying a desired lighting pattern on the surface of a wood layer is arranged by arranging a light emitting element 10 on a substrate 4 and connecting the substrate 4 to a base 9 to provide a light source A first step of obtaining the portion 11, a second step of laminating the wood layer 12 on the base 9 having the light source portion 11 so as to cover the light source portion 11, and the thickness of the laminated body A flange portion 14 having a rectangular cut surface is fixed to at least a part of the side surface 2 constituting the third portion, and the flange portion 14 protrudes from the side surface 2 in a substantially vertical direction. To do.

  Further, in the method of manufacturing the housing with a light emitting function, before or after the first step described above, a projecting plate 42 having a continuous wood grain pattern is pasted on the plate-like reinforcing layer 43, and the planar work material WM is attached. In the fourth step, the reinforcing layer 43 of the workpiece material WM is formed with V-shaped grooves 35 in the column direction and recesses 25 in the row direction in the plan view of the workpiece material WM. At the same time as the fourth step and the work body WM is bent along the V-shaped groove 35 to obtain the housing body 20, the flange portion 14 of the optical display laminate 1 is fitted into the recess 25 of the housing body 20. And a fifth step of attaching.

  Furthermore, in the method for manufacturing a casing with a light emitting function capable of displaying a desired lighting pattern on the surface of the wood layer of the present invention, the first projecting plate 42 having a wood grain pattern is pasted on the plate-like reinforcing layer 43, A V-shaped groove 35 is formed in the column direction in the plan view of the workpiece material WM2 in the first layer of the workpiece material WM2 and the reinforcing layer 43 of the workpiece material WM2; The second step of obtaining the cutout portion 251 continuously cut from the divided area of WM2, and the work material WM2 is bent along the V-shaped groove 35, and the stepped cutout portion 251 is formed at the opening end. A third step of obtaining the housing main body 220, a light diffusion layer 216 for adjusting the directivity of light from the light source unit 11 having the light emitting element 10, and a reinforcing layer 217 for reinforcing the light diffusion layer 216 are laminated. At substantially the same time, the reinforcing layer 217 and the light diffusion layer 21 A fourth step of engaged in the missing portion 251 cut around the, and having a fifth step of coating the second projecting plate 212 on the light diffusion layer 216 having a grain pattern, a.

  As described above, the structure in which the inner wall surface 23 and at least a part of the optical display laminate 1 intersect at a substantially right angle, more specifically, the side surface of the optical display laminate is fixed by the inner wall surface of the housing body. If it is a housing | casing with a light emission function, since advancing of the light to a side direction is prevented by the housing body which coat | covers the side surface of a light source part, it can prevent effectively that light leaks from the outer surface of a housing body. As a result, it is possible to remarkably reduce the light emission other than the viewing surface on which the lighting pattern appears, thereby improving the visibility of the lighting pattern. Moreover, the manufacturing method of the housing | casing with a light emission function which provides a flange part in the side surface of a light display laminated body can make a connection with a housing | casing main body easy. This is because it is possible to easily maintain a predetermined connection posture by fitting the flange portion into the recess of the housing body. In addition, since the amount of adhesive due to the connection can be significantly reduced, the time and cost required for drying can be greatly reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies a casing with a light emitting function and a manufacturing method thereof for embodying the technical idea of the present invention. The manufacturing method is not specified as follows. In addition, the member shown by the claim is not what specifies the member of embodiment. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are not intended to limit the scope of the present invention only to the description unless otherwise specified. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and symbol indicate the same or the same members, and detailed description thereof will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that a plurality of elements are constituted by the same member and the plurality of elements are shared by one member, and conversely, the function of one member is constituted by a plurality of members. It can also be realized by sharing. In addition, the contents described in some examples and embodiments may be used in other examples and embodiments.

  FIGS. 1 and 2 are perspective views of the housing with a light emitting function of the first embodiment, and FIG. 3 is a cross-sectional view taken along line III-III ′ of FIG. Moreover, in FIG. 3, the partially expanded view of the part enclosed by the circle is shown in the same drawing. The casing 100 with a light emitting function is a casing capable of displaying a desired lighting pattern 101 on the surface of a wood layer, and includes a light source inside the casing. In FIG. 1, the light source unit is in a non-energized state. In this state, the surface woody layer 12 having a grain pattern is not transparent so that the light source cannot be recognized. When the internal light source unit is energized, light appears on the viewing surface 3 of the wood layer 12 as shown in FIG. 2, and a desired lighting pattern 101 appears on the surface layer.

  As described above, the housing 100 with the light emitting function capable of projecting the lighting pattern 101 on the surface of the wood layer 12 includes a housing body 20 that is opened in at least one direction as shown in FIG. And the optical display laminate 1 that substantially closes 21. The housing body 20 constitutes an inner wall surface 23 on the opened inner side. On the other hand, the optical display laminate 1 is configured by laminating a base 9 including a light source unit 11 in which a plurality of light emitting elements 10 are arranged, and a wood layer 12 covering the light source unit 11. Further, the side surface 2 constituting the thickness of the optical display laminate 1 is fixed by an inner wall surface 23 in the opening 21 of the housing body 20. The light source unit 11 emits light when supplied with power, and the light travels from the inside to the outside of the wood layer 12. As a result, the transmitted light is transmitted in a substantially planar view from the viewing direction in the light display laminate 1. Recognized as a light pattern.

  Further, as shown in FIG. 2, the housing 100 with a light emitting function exposes the end surface 26 of the housing body 20 in a plan view from the viewing direction of the lighting pattern, and the outer periphery of the side surface 2 of the light display laminate 1. Is enclosed by the end face 26 of the housing body 20. Each corner of the housing body 20 is provided with a joint surface 27 formed from the outer corner to the inner corner at the corner of the housing body 20. The casing 100 with a light emitting function is configured such that adjacent surfaces of the casing body 20 are brought into contact with each other through the joint surface 27 and the box body 2 is configured in a frame shape so that the adjacent surfaces are substantially perpendicular to each other. Yes.

  What is important in the housing 100 with the light emitting function of the first embodiment is that the side surface 2 of the optical display laminate 1 is covered with the inner wall surface 23 of the housing body 20. Specifically, as shown in FIG. 3, the side surface 2 of the optical display laminate 1 and the inner wall surface 23 of the housing body 20 face in the opening 21, and in detail, substantially contact and fix. Is done. At least a part of the side surface 2 of the optical display laminate 1 and the inner wall surface 23 of the housing body 20 are in contact with each other, and preferably the entire side surface 2 is in contact with the inner wall surface 23. The housing 100 with a light emitting function in FIGS. 1 to 3 houses the optical display laminate 1 in the opening 21 of the housing body 20. Specifically, as shown in the enlarged view of FIG. 3, the casing 100 with a light emitting function is fixed to a posture including the outer side surface 2 of the optical display laminate 1 with the inner wall surface 23 of the opening edge of the casing body 20. doing. Further, in a plan view from the viewing direction in the housing 100 with a light emitting function, the viewing surface 3 of the optical display laminate 1 is substantially horizontal to the end surface 26 constituting the thickness of the housing body 20 or is deeper than the end surface 26. Preferably they are arranged. In the example of FIG. 3, the end surface 26 of the housing body 20 and the viewing surface 3 of the optical display laminate 1 are arranged to be substantially the same surface.

  In addition, the casing 100 with a light emitting function has an inner wall surface 23 that intersects at least a part of the optical display laminate 1 substantially perpendicularly from the opening end to the inner surface in the opening 21. In this way, in the light display laminate 1 in which the side surface 2 substantially orthogonal to the viewing surface 3 of the light display laminate 1 is covered by the housing body 20, the light emitted from the light source unit 11 leaks from the periphery of the viewing surface 3. It is possible to effectively reduce the output. In particular, when the light diffusing layer 16 is inserted between the base 9 and the wood layer 12 to weaken the directivity of the light emitted from the light emitting element 10, the light that has repeatedly reflected travels straight (the left direction in FIG. 3). ) As well as the side surface 2 side (vertical direction in FIG. 3). Since the light traveling toward the side surface 2 is absorbed or reflected by the housing body 20 facing the side surface 2, transmission to the outer surface 22 side of the housing body 20 to emit light in this region can be effectively reduced. That is, the light source light can be prevented from leaking around the viewing surface 3, and light emission can be substantially limited to the viewing surface 3 side. As a result, the contrast of light in the region where the lighting pattern 101 is desired to be displayed and the other region can be increased, and thus the visibility of the lighting pattern 101 can be increased.

(Flange part)
As described above, the casing 100 with the light emitting function of FIGS. 1 to 3 is fixed in a posture in which the periphery of the optical display laminate 1 is surrounded by the casing body 20, and light is transmitted from the outer peripheral side surface 2 of the optical display laminate 1. It can prevent leakage. A specific fixing method will be described below. The optical display laminate 1 has a flange portion 14 protruding outward from at least a part of the side surface 2, and the flange portion 14 is connected to the inner wall surface 23 of the housing body 20. The flange portion 14 is provided on the entire periphery of the side surface 2 of the optical display laminate 1, and the entire peripheral area of the flange portion 15 is fixed to the inner wall surface 23 of the housing body 20. The flange portion 14 provided in the entire peripheral area can effectively prevent light leakage of the light source unit 11. Or the flange part 14 is provided in a part of the side surface 2 of the optical display laminate 1, and the flange display 14 is intermittently connected to the housing body 20 to facilitate the optical display laminate 1 and the housing body 20. It is good also as a form which can be connected to.

  Further, as shown in FIG. 3, the housing 100 with a light emitting function is provided with a recess 25 along the shape of the flange portion 14 of the optical display laminate 1 on the inner wall surface 23 of the housing body 20. By fitting the part 14, the housing body 20 and the optical display laminate 1 can be easily fixed. The connection form in which the concave and convex shapes are complemented by the concave portion 25 and the flange portion 14 can naturally maintain the housing body 20 and the optical display laminate 1 in a predetermined posture by fitting. Compared with the conventional method in which the adhesive is solidified while keeping the casing body and the optical display laminate in a predetermined posture, the time and labor required for manufacturing can be saved, so that the yield is improved. In addition, the connection posture can be made consistent and a highly reproducible manufacturing method.

  Thus, the gap GP is generated between the side surface 2 of the optical display laminate 1 and the inner wall surface 23 of the casing main body 20 by connecting the housing main body 20 and the optical display laminate 1 by the fitting structure. Even in this case, the flange portion 14 protruding outward from the side surface 2 of the optical display laminate 1 is connected in contact with the inner wall surface 23 of the housing body 20, so that the gap GP is blocked by the flange portion 14. it can. Therefore, since the light blocking surface can be made continuous with the flange portion 14 from the side surface 2 of the optical display laminate 1 to the inner wall surface 23 of the housing body 20, it is possible to effectively prevent light from leaking from the gap GP.

  Therefore, the flange portion 14 is preferably made of a material that can block light. The flange portion 14 completely or at least partially impedes the light from the light source portion 11 toward the viewing surface 12, and is made of, for example, a multilayer film having different reflectivities. Or the thing which coat | covered the surface with the metal film and improved the reflectance of light can be utilized. The light display laminate 1 having the flange portion 14 can effectively prevent light from leaking from the outer surface of the other member while easily connecting to the other member in a predetermined posture.

(Light display laminate)
The optical display laminate 1 is formed by laminating the base 9 including the light source unit 11 and the wood layer 12 covering the light source unit 11 as described above. However, in the optical display laminate 1, an intervening layer 13 can be inserted between the base 9 and the wood layer 12. The optical display laminate 1 in FIG. 3 includes at least a light diffusion layer 16 that can adjust the directivity of light from the light source unit 11 and a reinforcing layer 17 that reinforces the light diffusion layer 16 as the intervening layer 13. As shown in FIG. 3, the light display laminate 1 of Example 1 has a wood layer 12, a light diffusion layer 16, a reinforcing layer 17, from the viewing direction, that is, from the surface side to the back (from left to right in FIG. 3). The base 9 is laminated in this order. Hereinafter, these members will be described in order.

(Woody layer)
The wood layer 12 has a surface having a wood grain pattern. The wood grain pattern can be artificially processed, for example, a plywood made by painting or printing a wood grain pattern on the surface of the base plate. Alternatively, natural wood grain may be used. For example, a thin plate obtained by cutting wood having a grain along the plate surface, or a decorative plate finished by stretching the thin plate on the surface can be used. Although it does not specifically limit as a board | plate material, A walnut, a cherry tree, and a bird's eye maple are preferable from a viewpoint of the designability and intensity | strength of a grain. Further, the wood layer 12 has a thickness capable of transmitting the light emitted from the light source, specifically 0.1 mm to 0.5 mm, more preferably 0.2 mm to 0.3 mm. The wood layer 12 thinner than 0.1 mm has a reduced strength and may be broken when subjected to an unintended impact. However, this does not apply to natural wood veneer processed sheets that have sufficient strength by adding reinforcing means such as compression. On the other hand, if the thickness exceeds 0.5 mm, the light transmission is remarkably reduced, and the visibility of the lighting pattern is poor. In Example 1, a 0.2 mm projecting plate was used. In addition, the wood layer may be painted. Further, by applying a sealing material such as abrasive powder in advance when coating the wood layer, the unevenness of the wood layer can be reduced, and as a result, more uniform light transmission can be obtained.

(Light diffusion layer)
The light diffusion layer 16 can relax the directivity of the light source and expand the viewing angle of the lighting pattern. In addition, the light diffusion layer 16 can serve as a filter that makes the amount of light passing through the viewing surface 3 uneven, that is, equalizes the amount of light passing through the lighting pattern 101. As a result, the light unevenness of the lighting pattern 101 on the viewing surface 3 can be extremely reduced. In Example 1, the light diffusion layer 16 was a paper layer. The paper layer 16 may be made of plant fiber or synthetic paper made mainly of synthetic resin such as chemical fiber or film. However, it is preferable that the paper layer contains fine fibers, and by using these fibers, it is possible to avoid light blocking and uneven distribution of the passing amount and to achieve a uniform transmission amount. Specific examples of the paper layer 16 include Japanese paper and tracing paper. Japanese paper is strong because long fibers are intertwined closely. Moreover, Japanese paper has a space between the fibers, and light is refracted and reflected there, so that the translucency can be moderately suppressed. Tracing paper, on the other hand, has a dense paper layer structure and no voids between fibers, so that light is transmitted and has high transparency. Therefore, the light quantity which permeate | transmits the optical display laminated body 1 whole can be adjusted as desired by selecting the material of paper quality suitably considering the translucency of the wood layer 16 to laminate | stack.

  In particular, if plain white or Japanese paper of the same color as the veneer is used as the light diffusing layer 16, the outline of the light emitting element 10 in the light source unit 11 can be moderately blurred while transmitting light. Can be expressed in a clear dot shape. Further, it is possible to effectively prevent the shadow in the thickness of the optical display laminate 1 from appearing on the surface side. Further, the paper layer 16 that can have a uniform transmission amount can prevent fibers from bleeding and being projected onto the surface of the veneer 12 when the light source is transmitted, that is, the grain pattern of the veneer 12 in the lighting pattern 101 that appears. It is preferable because it is an emergent light with a high decorative effect. Further, the paper layer 16 can be provided with other functionalities in addition to the characteristics of Japanese paper, such as increasing the moisture resistance and weather resistance by laminating the surface with a resin.

  By the way, the optical display laminated body 1 has a possibility that the dimension of each member may change by the installation environment, the temperature change by the light source part 11, or a humidity change, or the curvature of each member may generate | occur | produce. In particular, at the time of manufacture, the moisture content is increased by application of an adhesive, the moisture content is decreased by pressing for adhesion, and at the time of use, heat is generated from the LED light source when the LED is turned on, so It is in an environment where the moisture content of the water tends to change. As a result, the dimensional change accompanying the moisture content change of the plurality of materials constituting the optical display laminate 1 is different, and warpage occurs. The paper layer 16 has an effect of preventing such warpage of each member. Accordingly, the paper layer 16 has substantially the same outer shape as the wood layer 12 and the reinforcing layer 17 and covers almost the entire surface of these members, whereby the warpage of each member can be more effectively prevented. Further, by sucking in the extra adhesive applied to the layer on which the paper layer 16 is in contact, it is possible to effectively reduce the stain pattern caused by uneven application of the adhesive.

  The paper layer 16 preferably has a light transmittance of 30% to 70%. When the transmittance exceeds 70%, the diffusibility of the emitted light from the light source unit 11 side is weakened, the viewing angle is reduced, and the arrangement pattern of the light emitting elements 10 is exposed from the viewing surface 3. On the other hand, if the transmittance is less than 30%, the appearing lighting pattern becomes extremely unclear and it becomes difficult to recognize a significant pattern. Therefore, if the light transmittance is in the above range, the amount of light transmitted through the paper layer 16 in both directions is preferably maintained in a balanced manner. The paper layer 16 is preferably 0.05 mm to 0.2 mm. According to the test conducted by the inventor of the present application, if it is 0.05 mm or more, it is possible to eliminate excessive light transmission and prevent an unintended member from being projected on the surface of the door, while the paper layer 16 is If it is 0.2 mm or less, the light transmittance can be maintained, and the visibility degradation of the lighting pattern can be avoided. In particular, when tracing paper is employed for the paper layer 16, it is preferable that the thickness of the tracing paper is 0.05 mm to 0.08 mm so that the above-described effects can be enjoyed.

(Reinforcing layer)
Further, the optical display laminate 1 has a reinforcing layer 17 capable of reinforcing the protruding plate 12 and the paper layer 16. The reinforcing layer 17 has a size that can include at least the protruding plate 12 and the paper layer 16 having substantially the same outer size. The reinforcing layer 17 attaches the thin protruding plate 12 or the paper layer 16 to prevent warpage or breakage that is likely to occur with the protruding plate 12 or the paper layer 16 alone. The reinforcing layer 17 is made of a material that can transmit light from the light source unit 11, and for example, PET resin, acrylic resin, or the like can be used. In Example 1, a PET resin sheet was used as the reinforcing layer 17. A PET resin sheet (polyethylene terephthalate resin) has a light-transmitting property and a high light guiding effect. Further, the PET resin sheet 17 has waterproofness and impact resistance, so that the resistance of the protruding plate 12 and the paper layer 16 laminated thereon can be enhanced. Moreover, since it is excellent in heat resistance, thermal deformation due to heat generated from the light source unit 11 can be suppressed. The reinforcing layer 17 is preferably 1.0 mm to 2.0 mm in thickness so that both strength and translucency can be achieved.

  Moreover, the optical display laminated body 1 laminated | stacked in order of the wood layer 12, the paper layer 16, and the reinforcement layer 17 can adhere each member firmly. This is because the paper layer 16 interposed between the wood layer 12 and the reinforcing layer 17 can improve the wettability of the adhesive in the resin reinforcing layer 17. As a result, the paper layer 16 sandwiched between the wood layer 12 and the reinforcement layer 17 can be firmly bonded to the wood layer 12 and the reinforcement layer 17 on the front and back surfaces, respectively. As a result, the wood layer 12 and the reinforcement layer 17 are reinforced. Compared with the case where the layer 17 is directly bonded, the adhesion between the wood layer 12 and the reinforcing layer 17 can be enhanced.

(Base)
The base 9 includes a light source unit 11 in which a plurality of light emitting elements 10 are arranged. In the optical display laminate 1, the light emitting element 10 is arranged on the substrate 4, and the substrate 4 is connected to the base 9 to obtain the light source unit 11. FIG. 4 is a plan view of the light source unit 11. As shown in FIG. 4, the light source unit 11 is a collection of light emitting elements 10 that are a plurality of point light sources. As the light emitting element 10, various illumination lights such as discharge light emission and electroluminescence can be used. Specific examples include semiconductor elements such as LEDs and LDs, organic EL, and fluorescent lamps using luminescence.

  In the example of FIG. 4, an LED is used as the light emitting element 10. As a result, it can be driven at a low voltage and a low current, so that power consumption can be suppressed, durability and reliability can be improved, and power consumption can also be reduced. In addition to high brightness, various colors can be reproduced by mixing red, green, and blue light at an appropriate ratio. Furthermore, the LED is robust and excellent in impact resistance. In addition, since it has a long life, it is possible to reduce the labor and cost of replacing the light source and to realize maintenance-free. Furthermore, since the calorific value is small, the thermal influence on the surrounding members is relatively small. In the first embodiment, the LEDs 10 are arranged on the substrate 4 in a matrix shape that is parallel to the viewing surface 3 and in a matrix shape. The number of LEDs 10 to be used is appropriately set according to the size of the sign pattern to be displayed, the required light quantity, and the like. Since the LED 10 is a current control element, the light emission amount can be adjusted by the amount of current, and the output linearity is excellent and preferable.

  Moreover, although LED10 of various shapes, such as a cannonball type and a surface mount type, can be employ | adopted as LED10, surface mount type (SMD type) LED with thin thickness is preferable. Thereby, the thickness of the door can be easily changed. For example, the thickness can be reduced, and the thickness of the optical display laminate 1 can be adjusted via a spacer to add another member such as a heat insulating material.

  The light source unit 11 includes an LED group 10a in which the LEDs 10 are arranged in a matrix of a plurality of rows and a plurality of columns and in a planar shape. Each LED 10 is arranged in a direction in which the traveling direction of the emitted light is substantially orthogonal to the wood layer 12. Further, the number of mounted LEDs 10 is not particularly limited, and can be, for example, 4 rows × 4 columns, 16 rows × 16 columns, 24 rows × 24 columns, or the like. If the number of LEDs 10 is increased, the number of dots constituting the lighting pattern increases, so that the contour of the appearance lighting pattern can be expressed smoothly. On the other hand, heat generation and power consumption by the light source can be reduced by suppressing the number of placement. In the example of FIG. 4, three unit-shaped LED groups in which 4 rows × 4 columns are mounted on one substrate are connected in a straight line. For convenience, the first LED group 10a and the second LED group 10b from the left in FIG. This is referred to as a third LED 10c. Since the unit-shaped LED group can connect the LED groups having the same shape in a daisy chain, it can correspond to light emitting areas of various sizes by changing the number of connections. Moreover, the light source unit 11 may mount all the LEDs 10 on one substrate 4, or may prepare a different substrate 4 for each LED group. In the example of FIG. 4, the boards 4a, 4b, and 4c on which the LED groups 10a, 10b, and 10c can be mounted are arranged apart from each other, and fixed by fixing ribs 5 that connect parts of the boards 4a, 4b, and 4c. ing. Further, the LED 10 can be fixed to the optical display laminate 1 by connecting the fixing rib 5 to the base 9. In this way, by providing a plurality of substrates 4 corresponding to each small group of the light emitting elements 10 and separating the substrates 4 from each other, the surface area by which the substrate 4 to which heat generated from the light emitting elements is conducted can be exposed to the outside air. As a result, heat dissipation is improved, which is preferable.

  Therefore, the substrates 4a, 4b, and 4c are preferably made of a material that fixes the light emitting element 10 and has excellent thermal conductivity. Thereby, heat dissipation can be further improved and the life life of the light emitting element 10 can be improved. Specifically, a glass epoxy substrate, a flexible substrate, or a ceramic substrate can be used. Further, the number of the substrates 4 is not particularly limited, and can be appropriately determined depending on the display area of the lighting pattern. Further, the arrangement direction of the substrates 4 is not particularly limited, and the substrates 4 can be arranged in various ways such as a straight line or a plane. In the example of FIG. 4, three substrates 4 a, 4 b, 4 c are arranged in a straight line, and the light source unit 11 in which the LED 10 is mounted on each substrate 4 a, 4 b, 4 c is arranged in the direction in which the substrates 4 are arranged with respect to the viewing surface 3. It is fixed so that is in the horizontal direction.

  The light source unit 11 is connected to a power source through a switch, and driving power is supplied from the power source. The light source unit 11 is connected to a controller capable of controlling the drive current and drive pattern of the light emitting element 10. In this manner, by mounting the light emitting elements 10 in a dot matrix and having a structure in which the blinking of each light emitting element 10 can be controlled by the controller, the display of the lighting pattern can be recognizable without depending on the arrangement direction of the substrates 4. .

(Spacer 18)
In the optical display laminate 1, a spacer 18 can be sandwiched between the base 9 and the reinforcing layer 17 as shown in FIG. 3. The spacer 18 can adjust the separation distance between the base 9 and the reinforcing layer 17 by changing the thickness thereof. Thereby, since the separation distance between the light source unit 11 and the wood layer 12 can also be adjusted, the light emitting element 10 can be disposed at a separation distance at which the emitted light from the light source unit 11 can be projected clearly on the viewing surface 3. The spacer 18 is provided in the vicinity of the side surface 2 of the optical display laminate 1 and on the entire periphery of the base 9 or a part of the entire periphery. As with the flange portion 14, the spacer 18 can have a reflection function, and can reduce the light from the light source portion 11 from traveling in the direction of the side surface 2 of the optical display laminate 1.

(Adhesive)
The optical display laminate 1 is obtained by bonding the above-described members with an adhesive. The adhesive for pasting each member is not particularly limited as long as it can use a solvent-based pressure-sensitive adhesive and can stably bond each member such as a resin adhesive or cyanoacrylate. A plurality of adhesives may be used. Among these, vinyl acetate is suitable as a paper paste, and can enhance both the adhesiveness with the paper layer 16 and can fix both members within a suitable distance between the light source unit 11 and the wood layer 12. In particular, by using vinyl acetate, the light transmittance of the paper layer 16 when absorbed by the paper layer 16 is suitable, and the emitted light is directed at a separation distance within a specified range between the light source unit 11 and the paper layer 16. It is preferable that the balance between the diffusibility and the diffusibility is further increased, and that a lighting pattern having high visibility can be seen even from multiple directions.

(Case body)
On the other hand, the casing main body 20 that fixes the optical display laminate 1 inside has a wood layer having a substantially continuous grain pattern on the outer surface 22. That is, the casing 100 with a light emitting function continuously has substantially the same texture on the outer surface from the optical display laminate 1 to the casing body 20 as shown in FIG. As a result, it is possible to enjoy the beauty of wood grain in the wood layer 12 and to enhance the unexpectedness when the lighting pattern 101 is displayed.

  The housing body 20 can be formed of a single plate material having a wood grain pattern on the surface layer. Alternatively, as shown in FIG. 3, the casing main body 20 may be formed as a multilayer by laminating a protruding plate 42 on the surface of the reinforcing layer 43. The projecting plate 42 of the first embodiment has a thickness of 0.1 mm to 0.3 mm, and is made of the same material as the projecting plate 12 of the light display laminate 1, thereby unifying the overall texture of the casing 100 with a light emitting function and improving the design. Increased. The reinforcing layer 43 was MDF (medium specific gravity fiber board) having a thickness of 12 mm. MDF is obtained by adding a small amount of phenolic resin to wood fiber and hot pressing, and is preferable because it has high strength and can be easily subjected to secondary processing such as bending and drilling.

  Further, the housing body 20 may be formed with the light scattering layer 24 on the surface of the outer surface 22, that is, on the surface of the protruding plate 42, so that the outermost surface of the housing body 20 is matted. The light scattering layer 24 is added to the entire outer surface 22 or a part of the housing body 20. The light scattering layer 24 is preferably applied at least near the opening 21 of the housing body 20. By providing the light scattering layer 24 in a region where the possibility of light reception is high, it is possible to effectively avoid the light from the viewing surface 3 being reflected on the outer surface 22 of the housing body 20. Or by sticking the light-scattering layer 24 to the wide range of the housing body 20, it is possible to reduce the reflection of external illumination light and to increase the contrast between the viewing surface 3 and the outer surface 22. As a result, the visibility of the lighting pattern 101 on the viewing surface 3 is increased.

(Production method)
The housing 100 with a light emitting function is obtained by housing the optical display laminate 1 inside the housing body 20. The casing 100 with a light emitting function is obtained by assembling the optical display laminate 1 and the casing body 20 obtained as separate members. Therefore, the order of manufacture of the housing body 20 and the optical display laminate 1 is not particularly limited. Alternatively, during the manufacturing process of the housing body 20, the housing 100 with a light emitting function may be obtained substantially simultaneously with the assembly of the optical display laminate 1 obtained previously while being incorporated in the housing body 20. Hereinafter, an example of a method for manufacturing a casing with a light emitting function will be described.

(Light display laminate)
As a manufacturing method of the optical display laminate 1, a plurality of light emitting elements 10 are first arranged on the substrate 4 as described above, and the substrate 4 is connected to the base 9 to obtain the light source unit 11. On the base 9 having the light source unit 11, the reinforcing layer 17, the paper layer 16, and the protruding plate 12 are laminated in this order so as to cover the light source unit 11, thereby obtaining the optical display laminate 1. In stacking, a spacer 18 may be appropriately interposed between the base 9 and the reinforcing layer 17. Further, a flange portion 14 having a rectangular cut surface is fixed to at least a part of the side surface 2 constituting the thickness of the optical display laminate 1, and the flange portion 14 is protruded from the side surface 2 in the vertical direction.

(Case body)
On the other hand, the housing body 20 is formed in a box shape opened in at least one direction. The box body 20 is obtained by assembling a planar work material WM. FIG. 5 shows a state before the casing body 20 is assembled, that is, the work material WM is unfolded. The housing body 20 of FIG. 5 is a side view when viewed from the thickness direction. 5 is the outer surface side of the box body 20 when assembled. In the assembly of the housing body 20, first, the MDF that is the reinforcing layer 43 and the protruding plate 42 having a continuous wood grain pattern are firmly bonded via an adhesive to obtain an integrated plate-like workpiece material WM. Alternatively, in this plate shape, a work material WM may be obtained by further applying a matting material to the surface of the protruding plate 42 as appropriate. By bending the work material WM in which the projecting plate 42 is integrated in advance into a box shape, the wood pattern of the projecting plate 42 adhered to the surface can be continuously exposed over the adjacent surfaces. It can be a box body with excellent properties.

  Next, as shown in FIG. 6, in the planar work material WM, a groove 35 cut into a V shape from the reinforcing layer 43 side is formed. The depth of the groove 35 is set to be within the layer of the reinforcing layer 43. Specifically, the groove 35 is formed shallower than the thickness of the reinforcing layer 43 and does not reach the protruding plate 42. Thereby, since the notch is not formed in the protruding plate 42 which finally constitutes the outer surface side of the housing body 20, it is preferable because it is rich in design and impact resistance. The groove 35 is formed in a wedge shape having a wide opening while forming approximately 90 ° from the deepest part of the cut to the reinforcing layer 43 side. Although the formation method of the groove | channel 35 is not specifically limited, The groove | channel 35 can be obtained by dropping the rotary blade RB1 which sharpened the blade edge | tip at about 90 degrees from the reinforcement layer 43 side of the workpiece | work material WM. In the reinforcing layer 43, the groove 35 opened to approximately 90 ° on the upper surface side is bent into a valley fold with the adjacent surfaces adjacent to each other at the groove 35, so that the adjacent surfaces are substantially perpendicular to each other. Can be maintained.

  FIG. 7 is a perspective view of the work material WM of FIG. 6 in which the grooves 35 are formed as observed from the reinforcing layer 43 side. The work material WM in FIG. 7 has an area corresponding to a region where a plurality of housing bodies 20 are developed. Specifically, the work material WM is provided with a plurality of regions AR in the column direction, with the strip-shaped regions AR continuous in the row direction corresponding to the amount of expansion of one housing body 20. Further, a division area DA is provided between the development areas AR adjacent in the column direction, and the development areas AR can be divided into the individual development areas AR by separating the development areas AR in the division areas DA. That is, it is possible to cut the development areas AR of the plurality of housing main bodies 20 from one work material WM at a time to improve the yield. However, the entire work material WM may be sized corresponding to the amount of expansion of the single casing body 20.

  The work material WM has a plurality of grooves 35 extending in the row direction from the upper end to the lower end of the work material WM in FIG. A plurality of grooves 35 are provided at predetermined intervals in the left-right direction of FIG. In one development area AR, each section divided by the groove 35 continuously constitutes the left side surface portion 32, the bottom surface portion 31, the right side surface portion 33, and the top plate portion 34 of the housing body 20. Therefore, the arrangement locations of the groove 35 and the divided area DA substantially coincide with the vertical and horizontal lengths of the respective surfaces constituting the housing body 20.

  Furthermore, the concave portions 25 are provided in the row direction in the plan view of the workpiece material WM. The recess 25 is formed for each development area AR of the workpiece material WM. The concave portion 25 is a hollow having a U-shaped cross section, and is provided at a position separated from the end surface 26. As described above, the concave portion 25 fits the flange portion 14 protruding from the optical display laminate 1 to fix the optical display laminate 1 to the housing body 20. The means for forming the recess 25 is not particularly limited, but for example, a method similar to the groove 35 can be adopted. Specifically, as shown in FIG. 8, the rotary blade RB2 having a rectangular cross section is lowered from the reinforcing layer 43 side of the workpiece WM and cut into a concave shape. However, the depth of the concave portion 25 is set so as not to reach the protruding plate 42, and preferably within 30% to 80% of the thickness of the reinforcing layer 43. If the depression exceeds 80%, the thickness of the reinforcing layer 43 becomes too thin in the region where the concave portion 25 is formed, and the outgoing light from the light source unit 11 is easily transmitted through the reinforcing layer 43. Since the transmitted light from the housing body 20 reduces the contrast with the viewing surface 2, the visibility of the lighting pattern 101 is deteriorated. Moreover, since the hollow part shallower than 30% cannot receive the flange part 14 firmly, the optical display laminated body 1 cannot be fixed stably. Further, as shown in FIG. 7, the recess 25 is provided in the vicinity of the end surface 26 in the longitudinal direction of the development area AR and along the end surface 26. In addition, the order of formation of the groove | channel 35 and the recessed part 25 is not specifically limited.

  Then, the development area AR divided in the division area DA of the work material WM in FIG. 7 is bent in a direction in which adjacent surfaces are close to each other with the groove 35 as the center. Specifically, as shown in FIG. 9, the opposed inclined surfaces 38a and 38b of the V-shaped groove 35 are brought into contact with each other, and the development region AR is assembled in the direction in which the groove 35 is closed. Since the inclined surfaces 38a and 38b of the groove 35 opened at 90 ° are in contact with each other, naturally adjacent surfaces maintain a substantially right angle posture.

  Further, when assembling the development region AR, as shown in FIG. 10, the flange portion 14 of the optical display laminate 1 is assembled while being fitted in the recess 25 of the housing body 20. The casing main body 20 is configured such that a part of the flange portion 14 is locked to the recess 25 and the optical display laminate 1 is temporarily fixed to the casing main body 20, so that the end faces 26 of the casing main body 20 are not continuous. Are connected with an adhesive. In the example of FIG. 10, the series of the left side surface portion 32, the bottom surface portion 31, the right side surface portion 33, and the top plate portion 34 are bent while maintaining a substantially right angle posture with the adjacent surfaces. And the side end face 34a which comprises the thickness of the top-plate part 34, and the side end face 32a which comprises the thickness of the left side part 32 are connected via an adhesive material, and comprise this box-shaped visual recognition surface side. The optical display laminate 1 is fixed by a recess 25 provided in the vicinity of the end face 26. Alternatively, the housing 100 with a light emitting function may be configured such that the light display laminate 1 and the housing body 20 are separately manufactured and then the light display laminate 1 is installed in the housing body 20.

  Thus, in the manufacturing process of the casing 100 with the light emitting function, the continuous recesses 25 and the grooves 35 can be easily formed by using the work material WM. Moreover, the housing | casing 100 with a light emission function of Example 1 fixes the optical display laminated body 1 with the recessed part 25. FIG. Therefore, since the optical display laminate 1 can be temporarily fixed with the recess 25 in the course of manufacturing, the optical display laminate 1 and the housing body 20 can be easily and stably maintained in a predetermined posture. The housing 100 with a light emitting function can be manufactured. Moreover, compared with the conventional manufacturing method which fixed the optical display laminated body 1 to the housing | casing main body 20 via the adhesive material, the quantity of an adhesive material can be reduced, and also the attitude | position of both members until it dries. There is no need to maintain. Therefore, the time and labor required for drying can be reduced and the yield can be remarkably improved.

  Furthermore, the optical display laminate 1 of Example 1 has the flange portion 14 as an essential component, and the flange portion 14 is fitted into the concave portion 25 of the connecting member. Thereby, since this flange part 14 bears light interception, it can reduce that the light of the light source part 11 arrange | positioned in the back | inner side of the wood layer 12 becomes leakage light from the side surface which is not desired, and advances outside. .

  The casing 100 with the light emitting function of the first embodiment described above can be moved and installed at a desired place. However, the casing 100 with a light emitting function may be used in a fixed state. Moreover, the surface of the housing body 20 or the optical display laminate 1 is not limited to a planar shape, and may be a curved surface. Furthermore, it is good also as a form integrated in a part of other member. For example, it can be installed in a part of a building, furniture, or car body, and installed in a part of a pillar, a part of a door, or a part of a vehicle. In particular, by continuously adjoining a member having a wood layer, it is possible to obtain a sign having an unexpected appearance of a light pattern from a part without impairing the texture of the whole wood layer.

  Next, perspective views of the housing 200 with a light emitting function of the second embodiment are shown in FIGS. 11 and 12, and a sectional view taken along line XIII-XIII ′ of FIG. 11 and a partially enlarged view of a part surrounded by a circle are shown in FIG. Respectively. In the description of the case 200 with the light emitting function in the second embodiment, the same reference numerals are used for members having the same materials or functions as the case 100 with the light emitting function in the first embodiment, or the same reference numerals are used for corresponding members. Based on the above, the reference numeral with the hundreds is given as 200, and the detailed description is omitted as appropriate. A housing 200 with a light emitting function of FIGS. 11 to 13 is a housing capable of displaying a desired lighting pattern 101 on the surface of a wood layer, like the housing 100 with a light emitting function of the first embodiment. With a light source. In FIG. 11, the light source unit is in a non-energized state, and in this state, the light source cannot be recognized because the surface woody layer 212 having a grain pattern does not transmit the inside. When the internal light source unit is energized, light appears on the viewing surface 203 of the wood layer 212 as shown in FIG. 12, and the desired lighting pattern 101 appears on the surface layer.

  The main difference between the cases 100 and 200 with the light emitting function of Example 1 and Example 2 is the connection structure between the optical display laminate and the case body. Specifically, the shapes of the optical display laminate and the housing main body at the connecting portion are different. As shown in FIGS. 11 to 13, the housing 200 with the light emitting function of the second embodiment has an outer periphery of the light display laminate 201 along the outer surface 222 of the housing body 220 in a plan view from the viewing direction of the lighting pattern. It is configured as follows. Specifically, the wood layer 212 covers the end surface 226 of the housing body 220, and the outer peripheral surface of the wood layer 212 and the outer surface 222 of the housing body 220 are disposed on substantially the same surface. That is, the entire viewing surface 203 is composed of the wood layer 212, and the end surface 226 of the housing body 220 is not exposed. Furthermore, since the wood pattern from the visual recognition surface 203 to the outer surface of the housing body 220 can be made continuous, the design is improved.

  Further, as shown in FIG. 13, in the case 200 with a light emitting function, the thickness of the case main body 220 is made thin at the opening end to form a stepped inner wall surface 223, and the outer surface 222 remains flat while maintaining the flat surface. The opening area of the body main body 220 is increased toward the opening end. In the example of FIG. 13, one step 250 is provided at the opening end, but a plurality of steps may be provided.

  On the other hand, the side surface 202 of the optical display laminate 201 is configured to fit with the inner wall surface 223 of the housing body 220. The optical display laminate 201 in FIG. 13 has the viewing surface side as the maximum area and the area on the back surface side of the viewing surface is reduced. As a result, one step 255 is provided on the side surface 202. However, the number of steps 255 provided on the side surface 202 of the optical display laminate 201 may be matched with the number of steps 250 on the inner wall surface 223 of the housing body 220, and may be one or more. The steps 255 and 250 of the side surface 202 of the optical display laminate 201 and the inner wall surface 23 of the housing body 220 are fitted to each other, and the optical display laminate 201 is fixed to the housing body 220.

  Similar to the first embodiment, the optical display laminate 201 is formed by laminating a base 9 including a light source unit 11 in which a plurality of light emitting elements 10 are arranged, and a wood layer 212 covering the light source unit 11. The optical display laminate 201 includes an intervening layer 213 between the base 9 and the wood layer 212. The intervening layer 213 includes at least a light diffusion layer 216 that adjusts the directivity of light from the light source unit 11 and a reinforcing layer 217 that reinforces the light diffusion layer 216. The functional characteristics of each member are the same as those in the first embodiment, and the same material can be used. However, what is important for the optical display laminate 201 of Example 2 is that the wood layer 212 is large enough to constitute the entire viewing surface 203, and the outer periphery of the wood layer 212 is along the outer surface 222 of the housing body 220. It is. The light diffusing layer 216 and the reinforcing layer 217 stacked on the wood layer 212 have substantially the same outer size, but the outer size is smaller than that of the wood layer 212 so that the side surface 202 is formed in a stepped shape. Further, the base 9 and the spacer 18 that is appropriately sandwiched between the base 9 and the reinforcing layer 17 have an outer size smaller than that of the reinforcing layer 217 and are more open than the step 250 of the housing body 220. It is arranged on the back side in the part 221.

  The thickness tk1 of the housing body 220 at the opening end is preferably 30% to 80% as compared with the thickness tk2 on the back side of the opening 221. When the thickness tk1 is greater than 80%, the cutout amount of the thickness tk2 at the opening end of the housing body 220 is too small. As a result, the connection region that fits the step 255 of the optical display laminate 201 is reduced, so that the connection strength is increased. It will decline. On the other hand, when the thickness tk1 is smaller than 30%, the notch amount of the thickness tk1 at the opening end of the housing body 220 is excessive, in other words, the thickness tk1 becomes too thin, and the strength of the housing body 220 itself at the opening end is too small. It will be reduced. Therefore, the thickness tk1 at the opening end of the housing body 220 is preferably set in the above range.

  Further, the depth wd from the end face 26 in the cutout portion 251 preferably corresponds to the total thickness of the laminated members excluding the wood layer 212, that is, the laminated members having an outer size smaller than that of the wood layer 212. . As a result, it is possible to easily fix the laminated member other than the wood layer 212 to the cutout portion 251 in the manufacturing method described later. Further, the surface of the light diffusion layer 216 fixed to the notch 251 can be made substantially flush with the end surface 26 of the housing body 220. As a result, the wood layer 212 disposed on the outermost surface is changed to the light diffusion layer 216 and the end surface. 26, both the optical display laminate 201 and the housing body 220 can be firmly connected.

  As described above, since the casing 200 with the light emitting function of the second embodiment is configured by the wood layer 212 of the light display laminate 201 in the almost entire surface of the viewing surface 203, the optical display in the front view from the viewing surface 203 is performed. It is difficult to recognize the joint between the laminate 201 and the housing body 220. Therefore, since the housing 200 with the light emitting function can be apparently recognized as an integrated wooden block, it is possible to enhance the design and further enhance the unexpectedness that the light pattern appears.

  In addition, as shown in FIG. 3, the optical display laminate 201 and the housing body 220 are connected in steps. As a result, it is possible to avoid leakage of light emitted from the light source unit 11 from an undesired region, for example, the side surface 202 side or the outer periphery of the viewing surface 203. This is because the outer size of the reinforcing layer 217 and the light diffusion layer 216 disposed in front of the base 9 including the light source unit 11 is made larger in the light traveling direction. Due to the difference in size between the base 9 and the members disposed in the front, the emitted light from the light source unit 11 travels in the forward direction, but stray light traveling in the outer peripheral direction can be blocked. Further, by maximizing the outer size of the wood layer 112 disposed at the forefront, even if leak light proceeds in the gap GP, the leak light proceeds outward with the wood layer 112 closing the gap GP. Can be prevented.

  As described above, it is preferable that the connection region between the optical display laminate 201 and the housing main body 220 is formed in a step shape so that leakage light can be blocked over a plurality of stages. Moreover, since the connection area of the optical display laminated body 201 and the housing body 220 can be increased, the connection strength of both can be increased.

(Production method)
14, 15, and 16 are explanatory diagrams of a manufacturing method according to the housing 200 with the light emitting function of the second embodiment. A method for manufacturing the casing 200 with the light emitting function of the second embodiment will be described with reference to FIGS. However, in the method for manufacturing the case 200 with the light emitting function of the second embodiment, the description of the points similar to the method for manufacturing the case 100 with the light emitting function will be omitted as appropriate. The housing 200 with a light emitting function is obtained by first obtaining the housing body 220 and then incorporating the optical display laminate 210 into the housing body 220. The housing body 220 is manufactured by a method similar to that of the first embodiment, and specifically, the only difference is that a notch 251 is provided instead of the recess 26.

  As in the first embodiment, the housing body 220 according to the second embodiment firmly bonds the MDF as the reinforcing layer 43 and the protruding plate 42 having a continuous wood grain pattern with an adhesive as shown in FIG. Then, an integrated plate-like workpiece material WM is obtained. Alternatively, in this plate shape, a work material WM may be obtained by further applying a matting material to the surface of the protruding plate 42 as appropriate. Further, as shown in FIG. 6, in the planar work material WM, a groove 35 cut into a V shape from the reinforcing layer 43 side is formed. FIG. 14 shows a perspective view of the workpiece material WM2 of Example 2 in which the grooves 35 are formed, as observed from the reinforcing layer 43 side.

  A workpiece material WM2 of Example 2 shown in FIG. 14 is similar to the workpiece material WM of Example 1 shown in FIG. 7, but is different in that notches 251 are provided in the row direction. . The cutout portion 251 is cut in a region continuous with the end surface 226 of the development region AR. The formation method of the notch part 251 is not specifically limited, The method similar to the recessed part 25 of Example 1 is employable. Specifically, as shown in FIG. 15, the rotary blade RB <b> 2 having a rectangular cross section is lowered from the reinforcing layer 43 side of the workpiece material WM, and the workpiece material WM <b> 2 is cut as appropriate by moving in the left-right direction to end face 226. The notch portion 251 is obtained by reducing the thickness at. The cutting depth is adjusted to a range in which the thickness tk1 of the workpiece WM2 cut as described above satisfies 30% to 80% of the thickness tk2 in the non-cutting region. The depth wd of the notch 251 is adjusted to be approximately equal to the total thickness of the light diffusion layer 216 and the reinforcing layer 217 fitted into the notch 251.

  The bottom surface of the cutout portion 251 is formed so as to be substantially parallel to the surface of the work material WM2, and as a result, the work material WM2 is formed in a step shape in the vicinity of the end surface 226. However, the timing at which the notch portion 251 is formed may be the same as the stage of the workpiece material WM2, in which the notch portions 251 may be simultaneously applied to a plurality of development areas AR, or after the workpiece material WM2 is cut into each development area AR, May be provided in the development area AR.

  As in the first embodiment, as shown in FIG. 9, in the development area AR divided by the division area DA of the work material WM, the development area AR is bent while the adjacent surfaces around the groove 35 are bent. As a result, the housing body 220 is obtained.

  FIG. 16 is an exploded perspective view of the housing 200 with a light emitting function according to the second embodiment. A process of obtaining the casing 200 with a light emitting function by fitting the optical display laminate 201 to the casing body 220 obtained in the previous step will be described with reference to FIG. In the optical display laminate 201, the light diffusion layer 216 and the reinforcing layer 217, excluding the projecting plate that is the wood layer 212, are bonded together, and the base 9 is mounted through the spacers 18 almost simultaneously. The optical display laminate 201 excluding the protruding plate 212 is fitted into the opening 221 of the housing body 220 to close the opening end. Specifically, while the base 9 is disposed in the opening 221, the adhered light diffusion layer 216 and reinforcing layer 217 are fitted and fixed to the notch 251 of the housing body 220. That is, the periphery of the reinforcing layer 217 and the light diffusing layer 216 is locked to the stepped shape of the inner wall surface 23 at the opening end of the housing body 220, and at the same time, the reinforcing layer 217 and the light in the plan view from the viewing surface 203. The diffusion layer 216 is enclosed by the end surface 226 of the housing body 220. Further, the surface 200 of the light diffusion layer 216 and the end surface 226 of the housing main body 220 are formed to have substantially the same surface shape, and this surface shape is continuously covered with the protruding plate 212 with an adhesive, whereby the housing 200 with a light emitting function. Get.

  The casing 200 with a light emitting function obtained by forming the inner wall surface 23 of the opening end portion in a step shape and locking a part of the side surface 202 of the optical display laminate 201 in this step shape can be easily manufactured. This is because even if there is a slight error in the size of the reinforcing layer 217, the closing of the opening 221 is not affected as long as it fits in the notch 251 constituting the step shape. . Further, when the casing body 220 and the optical display laminate 201 are connected, the stepped shape is formed so that the reinforcing layer 217 and the light diffusion layer 216 are fitted into the notch 251 of the inner wall surface 223 of the casing body 220. It is only necessary to mount and lock, and the opening can be easily closed. Furthermore, the protruding plate 212 constituting the visual recognition surface 203 is easy to position because it is adhered to the outermost surface in the final process. Specifically, it is preferable because the protruding plate 212 can be appropriately disposed along the outer surface 222 of the housing main body 220 without depending on the positions of the reinforcing layer 217 and the light diffusion layer 216 already mounted.

  Note that an adhesive may be interposed when the stepped shape of the optical display laminate 201 is fitted to the opening end of the housing body 220. In the housing 200 with a light emitting function according to the second embodiment, the connection region between the housing body 220 and the optical display laminate 201 has a staircase shape, and the protruding plate 212 covers the end surface 226 and the entire viewing surface 203. It is characterized by the size to be. As a result, even if a gap due to an adhesive or the like occurs in the connection region, the gap is formed in a zigzag shape, and the linear optical path in the outer peripheral direction is blocked, so that the leakage light is effectively prevented. Can be reduced.

  The casing with a light emitting function and the manufacturing method thereof according to the present invention can be suitably used for a box, a door, a bulletin board, an information transmission device, a floor, a ceiling, a panel, a signboard, and the like.
