Description

  The present invention relates to a semiconductor light-emitting element holder to which a semiconductor light-emitting element (LED) can be attached, a semiconductor light-emitting element module, and a lighting fixture.

As a conventional example of a lighting fixture using one semiconductor light emitting device (LED) of high brightness type, for example, a base member, a metal chassis (heat radiating member) fixed to the base member, and an LED attached to the chassis The chassis in a state where the board and the connector are sandwiched between the LED unit that is an integrated body of the board and the board, the connector that is electrically connected to the board and the power source (provided with contacts), and the chassis. A metal frame fixed to a base member and a light projecting cover member fixed to a base member in a state of surrounding the LED unit and capable of transmitting illumination light emitted from the LED are known.
When the electric power generated by the power source is supplied to the substrate through the connector (contact), the LED emits light, and the emitted illumination light passes through the light projecting cover member and is irradiated to the outside of the light projecting cover member. Furthermore, the substrate of the LED unit is in contact with the chassis, and the heat generated when the LED emits light is efficiently transmitted to the chassis through the substrate and dissipated from the chassis, so the LED becomes extremely hot and the LED's luminous efficiency decreases. Can be prevented.

However, the above lighting fixture has the following drawbacks.
In other words, when fixing the LED unit and connector to the chassis, first place the LED unit on the chassis, then temporarily place the connector on the board of the LED unit, and fix the metal frame that covers the connector in this state. It must be fixed to the chassis and connector by bolts.
However, when the metal frame is fixed to the chassis and the connector by the fixing bolt, the LED unit and the connector can be moved relative to the chassis, so that the fixing operation of the metal frame is not easy.
Moreover, in order to fix the LED unit and the connector (contact) to the chassis, a step of placing the LED unit on the chassis, a step of temporarily placing the connector on the substrate, a step of covering the connector with a metal frame, and Four steps of fixing the metal frame to the chassis with fixing bolts are required.
Further, when the LED unit and the connector are fixed to the chassis, the LED may be damaged by a metal frame or the like.
Furthermore, when the LED unit and the connector are fixed to the chassis using the metal frame and the fixing bolt, the fixing force (load) by the fixing bolt is applied to the LED unit (board) and the connector via the metal frame, and these There is a risk of causing deformation or the like in the member.

  It is an object of the present invention to fix a semiconductor light emitting element unit, which is an integrated body of a semiconductor light emitting element and a substrate, and a contact for supplying power to the substrate to another member in a simple and few process. An object of the present invention is to provide a semiconductor light-emitting element holder, a semiconductor light-emitting element module, and a lighting fixture that are less likely to damage a semiconductor light-emitting element or fix the semiconductor light-emitting element unit or contact when it is fixed to a member.

  A holder for a semiconductor light emitting device according to the present invention is disposed in a housing body having a housing space in which a semiconductor light emitting device unit that is an integrated body of a semiconductor light emitting device and a substrate can be placed, and the housing space formed in the case body The opening for illumination that exposes the semiconductor light emitting element to the outside of the case body, and the semiconductor light emitting element that is formed on the case body and that is positioned outside can be inserted into the housing space and disposed in the housing space A substrate exposure opening that exposes the substrate to the outside, a substrate holding portion that is formed in the case body and supports the substrate disposed in the accommodation space so as to be retained in the accommodation space, and is located in the accommodation space. And a contact electrically supported by the substrate and the power source, supported by the insulating part of the case body in a state.

  The case body may include an insulator that supports the contact, and a cover member that is attached to the insulator to form the housing space with the insulator.

Reflecting the illumination light emitted from the semiconductor light emitting element formed on the outer surface of the case body on the outer peripheral side of the illumination opening, from the outer surface side toward the inner peripheral side, toward the housing space side You may provide the taper-shaped reflective surface of the shape which approaches.
The substrate holding part may be an engaging claw that protrudes outward from the substrate exposure opening and supports the outer surface of the substrate.

  A module for a semiconductor light emitting element according to the present invention is characterized by comprising the above-mentioned holder for a semiconductor light emitting element and the above semiconductor light emitting element unit disposed in the accommodation space.

  The luminaire of the present invention includes a semiconductor light emitting element module, a heat radiating member that contacts the substrate exposed to the outside through the substrate exposure opening, the illumination light emitted by the semiconductor light emitting element can be transmitted, and the semiconductor light emitting device. And a light projecting cover member surrounding the element holder.

Since the holder for a semiconductor light emitting device of the present invention can be fixed to another member (for example, a heat dissipation member) in a state of being integrated with the semiconductor light emitting device unit and the contact (the semiconductor light emitting device unit and the contact are not relatively moved), Therefore, the semiconductor light emitting element unit and the contact can be easily fixed to another member.
In addition, since the semiconductor light emitting element holder and the semiconductor light emitting element unit are integrated in advance and the semiconductor light emitting element holder can be fixed to another member, it can be fixed to the other member with a small number of steps. Therefore, maintenance when replacing the old semiconductor light emitting element unit with a new one is easy.
Moreover, since the periphery of the semiconductor light emitting element unit and the contact is covered with the semiconductor light emitting element holder, the semiconductor light emitting element comes into contact with other members and is damaged when the semiconductor light emitting element holder is fixed to another member. The fear is small. Further, for example, when the semiconductor light emitting element holder is fixed to another member by a fixing bolt, the fixing force (load) by the fixing bolt does not reach the semiconductor light emitting element unit and the contact, so that these members are not deformed. . Therefore, the yield is good and the service life can be extended.
Furthermore, since the substrate of the semiconductor light emitting element unit is exposed to the outside through the substrate exposure opening, the heat of the semiconductor light emitting element can be efficiently dissipated to the outside by contacting the substrate that easily transmits the heat of the semiconductor light emitting element with the heat dissipation member. it can. Therefore, it is possible to prevent a decrease in light emission efficiency of the semiconductor light emitting element due to a high temperature.

The cover member 60 includes a flat substrate portion 61, and a substrate exposure opening 62 having a rectangular shape in plan view is formed as a through hole in the central portion of the substrate portion 61. Recessed recesses 63 are formed at two positions on the left and right sides of the front and rear edges of the substrate exposure opening 62. Further, at the four positions on the lower surface of the cover member 60, two presser protrusions 64 positioned immediately before the two front clearance recesses 63 and two pressers positioned immediately after the two rear clearance recesses 63. The projection 64 is protruded downward. Engagement convex portions 65 project upward at both front and rear side edges of the upper surface of the substrate portion 61, and engagement holes 66 are formed as through holes in the front and rear engagement convex portions 65. A pair of left and right contact support protrusions 67 project upward in the vicinity of the rear end of the right edge of the upper surface of the substrate 61. Circular through holes 68 are formed in the vicinity of two corners located on the diagonal line of the substrate part 61, and annular protrusions 69 are provided at positions corresponding to the through holes 68 on the upper surface of the substrate part 61, respectively. It protrudes upward.
The cover member 60 is attached to the lower surface of the insulator 20 that supports the anode side conductive member 40 and the cathode side conductive member 50 from below. Specifically, the front and rear engaging convex portions 65 are positioned in the front and rear engaging concave portions 25 while the lower surface of the insulator 20 is closed by the substrate portion 61, and the front and rear engaging projections 26 are associated with the corresponding engaging convex portions 65.

Further, the two elastic deformation pieces 38 (engagement claws 39) on the front side of the insulator 20 pass through the corresponding two escape recesses 42a and the two escape recesses 63 and protrude below the cover member 60. The elastic deformation piece 38 (engagement claw 39) passes through the corresponding two recesses 63 and protrudes below the cover member 60.
In this manner, the insulator 20 supporting the anode side conductive member 40 and the cathode side conductive member 50 and the cover member 60 are integrated to complete the LED holder 15 (see FIG. 8). Further, a space surrounded by the cable insertion groove 30 of the insulator 20, the LED storage recess 31, the contact storage recess 32, the right side recess 34, the front side recess 35, the left side recess 36, the contact insertion groove 37, and the cover member 60. Containment space.

The LED unit 70 includes a substrate 71 having the same shape as the substrate exposure opening 62, and one high-luminance type LED 74 (semiconductor light emitting element) that is electrically connected to an electric circuit (not shown) formed on the upper surface of the substrate 71. An anode 72 and a cathode 73 formed on both ends of the electric circuit are formed on the upper surface of the substrate 71, respectively. Note that a diffusion lens 75 (see FIGS. 1, 2, and 11) that covers the LED 74 may be fixed to the upper surface of the substrate 71 as necessary. Further, the LED unit is configured as a package type by covering the upper surface of the substrate 71 and the LED 74 with a sealant (not shown) made of a thermosetting resin material or an ultraviolet curable resin material having translucency and insulation. May be.
The LED unit 70 is integrated with the LED holder 15 by fitting into the substrate exposure opening 62 from below. When the substrate 71 of the LED unit 70 is fitted into the substrate exposure opening 62, the anode 72 contacts the rear contact end portion 56 while elastically deforming the LED anode contact 55 upward, and the cathode 73 is the LED cathode contact. Since the rear contact end 52 is contacted while elastically deforming 51 upward, the upward movement of the substrate 71 relative to the LED holder 15 is restricted. Further, the front and rear edges of the substrate 71 press the engaging claws 39 to elastically deform the elastic deformation pieces 38 outward (the front elastic deformation piece 38 is the front and the rear elastic deformation piece 38 is the rear). When the board 71 moves above the respective engaging claws 39 (when the board moves over the engaging claws 39), each elastic deformable piece 38 returns to the free state, and the four engaging claws 39 move from the lower side of the board 71. Engages in four places on the lower surface. Therefore, the LED unit 70 is held in a state where the lower surface of the substrate 71 is flush with the lower surface of the substrate portion 61 by the LED cathode contact 51, the LED anode contact 55, and the four engagement claws 39 (FIG. 10). reference). Even if the LED unit 70 elastically deforms each elastic deformation piece 38 outward, each elastic deformation piece 38 can only be deformed until it abuts the corresponding presser protrusion 64. Therefore, each elastic deformation piece 38 has an elastic limit. It will not be elastically deformed beyond. Further, when the diffusing lens 75 is provided, when the LED unit 70 is integrated with the LED holder 15, the diffusing lens 75 is loosely fitted in the illumination opening 21 (the diffusing lens 75 is positioned in the LED housing recess 31. The diffusing lens 75 is exposed above the insulator 20 through the illumination opening 21).
Thus, the LED module 10 is completed by integrating the LED unit 70 with the LED holder 15 (see FIG. 9).

  One end of two cables 77 can be connected to the LED module 10. The cable 77 having flexibility includes an electric wire 78 in which a large number of metal wires are bundled, and a covering tube 79 made of an insulating material that covers the surface of the electric wire 78. At both ends of each cable 77, the electric wire 78 is exposed by removing the covering tube 79. When one end of each of the two cables 77 is inserted into each of the two cable insertion grooves 30, the elastically deformed portion 48 corresponding to the exposed end of the electric wire 78 (the cable anode contact 47 </ b> A and the cable cathode contact 47 </ b> B). The elastic deformation portion 48 is contacted while being elastically deformed (in a direction approaching the main body portion side) (see FIG. 11). Therefore, when each cable 77 is connected to the cable anode contact 47A and the cable cathode contact 47B, the cable 77 cannot be pulled out smoothly even if a pulling force is applied to the cable 77. Therefore, when the cable 77 is pulled out from the cable insertion groove 30, the tip of a pin (not shown) is inserted into the cable insertion groove 30 through the pin insertion hole 27, and the elastic deformation portion 48 (the cable anode) is inserted by the tip of the pin. The contact pressure between the elastic deformation part 48 and the electric wire 78 is further reduced by further elastic deformation (in the direction approaching the main body side of the contact 47A and the cathode contact 47B for the cable). In this way, each cable 77 can be smoothly pulled out with a small pulling force.

The LED module 10 and the cable 77 having the above configuration can be used as components of the lighting fixture 80 shown in FIG.
The luminaire 80 includes a synthetic resin base member 81 having a circular shape in plan view. A concave portion is formed on the upper surface (lower surface in FIG. 12) of the base member 81, and the bottom surface of the concave portion (in FIG. 12). A chassis 82 (heat radiating member) made of a metal plate is fixed to the upper surface. In the LED module 10 integrated with the cable 77, the fixing bolts 83 are attached to the two through holes 24 from the corner recess 23 side while engaging the pressing protrusions 64 with the positioning recesses provided in the chassis 82. The male screw portions of the fixing bolts 83 inserted through the through-holes 24 are respectively screwed into two female screw holes (not shown) formed in the chassis 82, whereby the base member 81 (chassis 82) is engaged. It can be fixed. When the LED module 10 is fixed to the base member 81, the lower surface (upper surface in FIG. 12) of the substrate 71 exposed through the substrate exposure opening 62 contacts the chassis 82. Further, the upper surface (the lower surface in FIG. 12) of the base member 81 is covered with a hemispherical light projecting cover member 84 that covers the upper surface of the base member 81 and the LED module 10.
The lighting fixture 80 including the LED module 10, the cable 77, the base member 81, the chassis 82, the fixing bolt 83, and the light projecting cover member 84 is, for example, a light projecting cover member of the base member 81 as shown in FIG. It can be fixed to the ceiling plate 85 with a screw or the like with the side opposite to 84 facing upward. The end of the cable 77 opposite to the LED module 10 is pulled out above the ceiling plate 85 through a through hole 86 formed in the ceiling plate 85 and connected to a power source via a control device (not shown). When the switch (not shown) is switched from OFF to ON, the current generated by the power source causes the cable 77, the anode side conductive member 40 (cable anode contact 47A, LED anode contact 55), and the cathode side conductive member 50 ( The LED 74 emits light through an electric circuit of the substrate 71 via the cable cathode contact 47B and the LED cathode contact 51) (if a diffusion lens 75 is provided, it is diffused by the diffusion lens 75). The illumination light emitted from the LED 74 is directed toward the light projecting cover member 84 while being reflected by the tapered reflecting surface 22 of the insulator 20, passes through the light projecting cover member 84, and is irradiated to the outside. On the other hand, when the switch is switched from ON to OFF, the supply of current to the LED 74 is interrupted, and thus the LED 74 is turned off.

According to the present embodiment described above, the LED module 10 is integrated with the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, the LED anode contact 55, and the LED unit 70 ( Since the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, the LED anode contact 55, and the LED unit 70 are not relatively moved), the LED module can be fixed to another member (for example, the chassis 82). 10 can be easily fixed to another member.
Moreover, the LED module 10 can be fixed to another member (for example, the chassis 82) with a small number of steps. Therefore, maintenance when replacing the old LED unit 70 fixed to another member with a new one is easy.
Further, the LED anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, the LED anode contact 55, and the LED 74 are covered with the LED holder 15, so that the LED module 10 is attached to another member. There is little risk that the LED 74 (diffuse lens 75) may come into contact with other members when being fixed. Further, when the LED holder 15 is fixed to another member by the fixing bolt 83, the fixing force (load) by the fixing bolt 83 is the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact. 55 and the LED unit 70, the members are not deformed. Therefore, the LED module 10 has a good yield (can suppress the occurrence of defective products) and has a long service life.

Further, the heat generated by the LED 74 is dissipated from the substrate 71 and further transmitted from the substrate 71 to the chassis 82 and is also dissipated from the chassis 82, so that the heat of the LED 74 can be efficiently dissipated to the outside. Therefore, it is possible to prevent a decrease in the light emission efficiency of the LED 74 due to a high temperature.
In addition, since the LED module 10 includes the tapered reflecting surface 22 positioned in the immediate vicinity of the LED 74 (diffuse lens 75), the directivity of the illumination light can be controlled, and uneven brightness of the illumination light can be suppressed.
Further, as shown in FIG. 12, most of the head of the fixing bolt 83 is positioned in the corner recess 23 formed in the insulator 20 (the amount of protrusion of the fixing bolt 83 upward from the upper surface of the insulator 20 is small). Therefore, it is difficult for the illumination light to be blocked by the head of the fixing bolt 83.
Further, the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact 55 are not integrated, but are integrated as the anode-side conductive member 40 and the cathode-side conductive member 50, respectively. Therefore, the LED module 10 (LED holder 15) is assembled as compared with the case where the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact 55 are all separated. Is easy.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to the said embodiment, It can implement, giving various deformation | transformation.
For example, the case main body having the insulator 20 and the cover member 60 may be integrally formed by insert molding in which the anode-side conductive member 40 and the cathode-side conductive member 50 are placed inside a mold.
The elastic deformation piece 38 (engagement claw 39) may be formed not on the insulator 20 but on the cover member 60.
Further, a heat transfer sheet or the like may be interposed between the lower surface of the substrate 71 and the chassis 82. In this way, the substrate 71 and the engaging claw 39 are separated from each other, but the pressing force on the substrate 71 from the LED cathode contact 51 and the LED anode contact 55 does not disappear (becomes stronger). The conduction between the LED anode contact 55 and the LED cathode contact 51 is maintained.
When the lower surface of the substrate 71 is engaged with the engaging claw 39, the length (engagement) of the elastic deformation piece 38 is such that the lower surface of the substrate 71 protrudes downward from the substrate exposure opening 62 (the lower surface of the substrate portion 61). The position of the joint claw 39) may be set. In this way, when the LED module 10 is fixed to the base member 81, the lower surface of the substrate 71 can be brought into contact with the chassis 82 more reliably.
Also, the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact 55 may be separated from each other.
Furthermore, the number of LEDs 74 placed on the substrate 71 may be plural, or the LED module 10 (LED holder 15) may be used as a component of a lighting fixture of a different type from the lighting fixture 80.
