  With respect to the outer shape of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, each figure in FIG. 3 is formed in a rectangular shape, and from the light incident surfaces 21e to 25e to the incident surfaces 21e to 21e. The light guide member 21 to the light guide member 25 in which the through holes 21m to 25m are respectively formed toward the front end surfaces 21f to 25f opposed to 25e are shown. Specifically, for example, a light guide member 21 shown in FIG. 3A has a cylindrical shape from an incident surface 21e on which light from the light source 10 is incident toward a distal end surface 21f facing the incident surface 21e. A through hole 21m is formed. Note that the shape of the through hole 21m is not limited to a cylindrical shape, and for example, the through hole may be formed to have a polygonal shape or an elliptical shape. The light guide member 21 includes a side surface 21a, a side surface 21b, a side surface 21c, and a side surface 21d between the incident surface 21e and the tip surface 21f. Here, linear joining grooves 21g for attaching a fixture 31 of the attachment member 30 described later are formed in the horizontal direction on the side surfaces 21b and 21d of the light guide member 21, respectively. In addition, the light guide member 22 thru | or the light guide member 25 shown in FIG.3 (b) thru | or FIG.3 (e) consist of the same external shape as the lightguide member 21 shown to Fig.3 (a).

  In addition, regarding the external shape of the light guide member 21 to the light guide member 25 in which the through holes are formed in the vertical direction, the side surfaces of the light guide member 21 to the light guide member 25 illustrated in each drawing of FIG. 3 are limited to four surfaces. For example, it may be formed from a polyhedron such as an 8-sided surface or a 12-sided surface. Further, the through holes 21m to 25m formed in the light guide member 21 to the light guide member 25 pass through the respective light guide members, but are not limited to such a configuration. For example, a hole having a predetermined depth may be formed from the incident surface 21e of the light guide member 21 shown in FIG. 3A, or a hole having a predetermined depth may be formed from the front end surface 21f of the light guide member 21. May be.

  In addition, regarding the patterns formed on the side surfaces of the light guide member 21 to the light guide member 25 in which the through holes are formed in the vertical direction, each figure in FIG. 3 includes a light guide in which a concave pattern is formed with various specifications. The members 21 to the light guide member 25 are shown. Specifically, in the light guide member 21 shown in FIG. 3A, concave patterns 21h and patterns 21j arranged in a matrix are formed on the side surface 21a and the side surface 21c facing each other so as to face each other. Has been. Here, the pattern 21h and the pattern 21j are each formed in, for example, a pyramid shape and a matrix shape of 3 rows and 3 columns. Further, in the light guide member 21 shown in FIG. 3A, the concave pattern 21h arranged in a matrix of 3 rows and 3 columns on the side surface 21a and the matrix shape of 3 rows and 3 columns on the side surface 21b adjacent to the side surface 21a. The concave patterns 21i arranged in the vertical direction are alternately formed in the vertical direction so as not to be adjacent in the horizontal direction in FIG. Similarly, on the side surface 21d of the light guide member 21 shown in FIG. 3 (a), the concave pattern 21k arranged in a matrix with respect to the pattern 21h on the adjacent side surface 21a does not overlap in the vertical direction. Are alternately formed. Here, the pattern 21i and the pattern 21k are formed in a pyramid shape, for example, like the pattern 21h and the pattern 21j, and are formed in a matrix shape of 3 rows and 3 columns, respectively.

  Similarly, regarding the patterns formed on the side surfaces of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 22 shown in FIG. Further, with respect to the side surface 22a and the side surface 22b adjacent to each other, the concave pattern 22h and the pattern 22i arranged in a matrix of 3 rows and 3 columns are not vertically adjacent to each other in the horizontal direction in FIG. It is formed alternately with respect to the direction. In addition, the light guide member 23 shown in FIG. 3C has a concave pattern 23h and a pattern 23j arranged in a matrix of 3 rows and 3 columns with respect to the side surface 23a and the side surface 23c facing each other. Are formed identically. Here, the pattern 23h and the pattern 23j are formed in a pyramid shape, for example. Further, in the light guide member 24 shown in FIG. 3 (d), concave patterns 24h and patterns 24j arranged linearly with respect to the side surface 24a and the side surface 24c facing each other are formed in a non-facing manner. Yes. Further, in the light guide member 25 shown in FIG. 3 (e), concave patterns 25h, 25i, 25j, and 25k made of, for example, a pyramid are formed on the four surfaces of the side surface 25a, the side surface 25b, the side surface 25c, and the side surface 25d. Each is formed at a predetermined interval.

  In addition, regarding the optical characteristics of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 21 to the light guide member 25 shown in FIGS. Through holes 21m to 25m are formed from the light incident surface 21e to the light incident surface 25e toward the front end surface 21f to the front end surface 25f, respectively. Therefore, for example, in the light guide member 21 shown in FIG. 3A, the light incident from the incident surface 21e is transmitted between the side surface 21a and the through hole 21m, between the side surface 21b and the through hole 21m, and between the side surface 21c and the through hole. Multiple reflections can be made between 21 m and between the side surface 21 d and the through hole 21 m. Accordingly, in the light guide member 21, light incident from the incident surface 21e can be led out from the side surface 21a, the side surface 21b, the side surface 21c, and the side surface 21d in addition to the tip surface 21f facing the incident surface 21e. That is, in the light guide member 21, light incident from the incident surface 21e is derived from all surfaces except the incident surface 21e, and thus has optical characteristics excellent in light distribution characteristics. Further, for example, in the light guide member 21, the light incident from the incident surface 21 e and reflected by the through hole 21 m can be visually recognized through the side surface 21 a, the side surface 21 b, the side surface 21 c, or the side surface 21 d of the light guide member 21. That is, the through-hole 21m formed at the center of the light guide member 21 is recognized as a cylindrical light emitter from the outside of the light guide member 21, and thus is excellent in design.

  Further, regarding the optical characteristics of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 21 shown in FIG. 3A has a matrix shape on the side surface 21a and the side surface 21c facing each other. The concave patterns arranged in the same manner are formed facing each other, and the concave patterns arranged in a matrix are alternately formed on the side surface 21b and the side surface 21d facing each other. Since the concave pattern formed on each of the side surfaces 21a to 21d of the light guide member 21 has a matrix shape, the concave pattern can be clearly seen. Furthermore, the light guide member 21 can visually recognize, for example, a concave pattern 21j formed on the side surface 21c facing the side surface 21a through the side surface 21a through the angle at which the light guide member 21 is viewed. The concave pattern 21k formed on the side surface 21d adjacent to the side surface 21a can be visually recognized through 21a. Here, when the angle at which the light guide member 21 is visually recognized is changed, the way in which the concave patterns formed on the respective surfaces of the side surface 21a to the side surface 21d change and is visually recognized, which is excellent in design.

  Similarly, regarding the optical characteristics of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 22 shown in FIG. 3B has a side surface 22a and a side surface 22b adjacent to each other. Thus, the concave patterns 22h and the patterns 22i arranged in a matrix are alternately formed in the vertical direction so as not to be adjacent in the horizontal direction in FIG. In such a light guide member 22, a side surface 22a and a side surface 22b which are adjacent to each other and formed with a concave pattern and a side surface 22c and a side surface 22d which are adjacent to each other and are not formed with a concave pattern are combined to form a concave shape. The effect of diffused light due to the presence or absence of a pattern can be emphasized. Moreover, since the concave pattern formed in each surface of the side surface 22a thru | or the side surface 22b of the light guide member 22 is a matrix form, this concave pattern can be visually recognized clearly. Further, in the light guide member 22, since the concave pattern is not formed on the side surface 22c and the side surface 22d adjacent to each other, the light guide member 22 is formed at the center of the light guide member 22 when viewed from the side surface 22c or the side surface 22d. The reflected light reflected by the through hole 22m can be clearly seen.

  Furthermore, regarding the optical characteristics of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 23 shown in FIG. 3C has a side surface 23a and a side surface 23c that face each other. The concave pattern 23h and the pattern 23j arranged in a matrix of 3 rows and 3 columns are formed so as not to face each other. In such a light guide member 23, for example, the pattern 23h formed on the side surface 23a can be viewed horizontally through the side surface 23c. Moreover, in the light guide member 23, since the side surface in which the concave pattern was formed, and the side surface in which the concave pattern was not formed were combined alternately, the side surface of the light guide member 23 was visually recognized from arbitrary directions. In this case, the side surface on which the concave pattern is formed and the side surface on which the concave pattern is not formed can be viewed at a time, and the effect of diffused light by the concave pattern can be emphasized. Moreover, since the concave pattern formed in each surface of the side surface 23a and the side surface 23c of the light guide member 23 is a matrix shape, the concave pattern can be clearly recognized. Further, in the light guide member 23, since the concave pattern is not formed on the side surface 23b and the side surface 23d facing each other, the light guide member 23 is formed at the center of the light guide member 23 when viewed from the side surface 23b or the side surface 23d. The reflected light reflected by the through hole 23m can be clearly seen.

  In addition, regarding the optical characteristics of the light guide member 21 to the light guide member 25 in which through holes are formed in the vertical direction, the light guide member 24 shown in FIG. 3D has a side surface 24a and a side surface 24c opposite to each other. The concave pattern 24h and the pattern 24j arranged in a straight line are formed so as not to face each other. In such a light guide member 24, since there are few concave patterns compared with, for example, the light guide member 23 in which the concave patterns arranged in a matrix are formed, most of the light incident from the incident surface 24e is The concave pattern is not converted into diffused light and is directly derived from each side surface. Further, in the light guide member 25 shown in FIG. 3 (e), concave patterns 25h, 25i, 25j, and 25k made of, for example, a pyramid are formed on the four surfaces of the side surface 25a, the side surface 25b, the side surface 25c, and the side surface 25d. Each is formed at a predetermined interval. In such a light guide member 25, unlike the light guide member 24, most of the light incident from the incident surface 24 e is derived as diffused light by a concave pattern formed on each side surface.

  Next, regarding the outer shape of the light guide member 41 to the light guide member 45, which are modifications of the light guide member 20 in which the reflection holes are formed in the horizontal direction shown in FIG. 4, the pattern formed on the side surface, and the optical characteristics, This will be explained in order.

  Regarding the outer shape of the light guide member 41 to light guide member 45 in which the reflection holes are formed in the horizontal direction, each figure in FIG. 4 is formed in a rectangular shape, and a hole having a predetermined depth is formed on each side surface. Light guide members 41 to 45 are shown. Further, for example, the light guide member 41 is formed with a side surface 41a, a side surface 41b, a side surface 41c, and a side surface 41d between the incident surface 41e and the tip surface 41f. Further, for example, linear joining grooves 41g for attaching the fixture 31 of the attachment member 30 described later are formed in the horizontal direction on the side surfaces 41b and 41d of the light guide member 41, respectively. Here, in the light guide member 41 shown in FIG. 4A, a total of three reflection holes 41m avoid the concave pattern 21h arranged in a matrix with respect to the side surface 41a of the light guide member 41. Is formed. Similarly, in the light guide member 41 shown in FIG. 4A, a total of four reflection holes 41n avoid the concave patterns 41i arranged in a matrix with respect to the side surface 41b of the light guide member 41. Is formed. The reflection hole 41m and the reflection hole 41n have, for example, a cylindrical shape and are formed with a depth that is half the thickness of the light guide member 41. Further, the light guide member 42 shown in FIG. 4B is formed with a reflection hole 42m and a reflection hole 42n with the same specifications as those of the light guide member 41 shown in FIG.

  Further, regarding the outer shape of the light guide member 41 to the light guide member 45 in which the reflection holes are formed in the horizontal direction, the light guide member 43 shown in FIG. 4C has a reflection hole 43m, a reflection hole 43n, and a reflection hole 43p. , And the reflection holes 43q avoid the concave patterns arranged in a matrix form on the four side surfaces 43a, 43b, 43c, and 43d of the light guide member 43, respectively, from the top to the bottom. Each one is formed so as to descend like a spiral staircase. In addition, the reflective hole 43m, the reflective hole 43n, the reflective hole 43p, and the reflective hole 43q are formed in a cylindrical shape, for example, and are formed from a depth half the thickness of the light guide member 43. Further, in the light guide member 44 shown in FIG. 4D, the reflection hole 44n is not adjacent to the concave pattern formed on the adjacent side surface 44a and the side surface 44c in the left-right direction in FIG. In addition, a total of four are formed with respect to the side surface 44 b of the light guide member 44. Similarly, in the light guide member 44 shown in FIG. 4D, the reflection hole 44q is not adjacent to the concave pattern formed in the adjacent side surface 44a and the side surface 44c in the left-right direction in FIG. Thus, a total of three are formed with respect to the side surface 44 d of the light guide member 44. Note that the reflection hole 44n and the reflection hole 44q have, for example, a cylindrical shape and are formed with a depth that is half the thickness of the light guide member 44.

  Similarly, regarding the outer shape of the light guide member 41 to the light guide member 45 in which the reflection holes are formed in the horizontal direction, the light guide member 45 shown in FIG. 4 (e) has a reflection hole 45m, a reflection hole 45n, and a reflection hole. 45p and the reflection hole 45q are formed so as to descend in a spiral staircase from the top to the bottom with respect to the four side surfaces 45a, 45b, 45c and 45d of the light guide member 45. Yes. In addition, the reflective hole 45m, the reflective hole 45n, the reflective hole 45p, and the reflective hole 45q are formed in a cylindrical shape, for example, and are formed from a depth that is half the thickness of the light guide member 45.

  In addition, regarding the external shape of the light guide member 41 to the light guide member 45 in which the reflection holes are formed in the horizontal direction, the side surfaces of the light guide member 41 to the light guide member 45 illustrated in each drawing of FIG. 4 are limited to four surfaces. For example, it may be formed from a polyhedron such as an 8-sided surface or a 12-sided surface. Moreover, although each reflection hole formed in the light guide member 41 thru | or the light guide member 45 is formed in each light guide member by the predetermined depth, it is not limited to such a structure. For example, it is good also as a structure which forms the reflective hole penetrated in the horizontal direction with respect to each light guide member.

  Further, regarding the patterns formed on the side surfaces of the light guide members 41 to 45 in which the reflection holes are formed in the horizontal direction, the light guide members 41 to 45 shown in FIG. Concave patterns corresponding to the optical member 21 to the light guide member 25 are formed.
