[Feature structure]
A characteristic configuration of the illumination light source 10 will be described. The illumination light source 10 is characterized in that three members constituting the outer casing, that is, the translucent panel 11, the casing 12, and the support member 13 are collectively fixed by screws 21.

  More specifically, the translucent panel 11, the housing 12, and the support member 13 are formed in an overlapping portion 22 in which the fixing portion 11a, the fixing portion 12a, and the fixing portion 13a overlap in the Z-axis direction. The screws 21 are inserted into the through holes and fixed together.

  Thereby, the light source 10 for illumination with which members were fixed by simple structure is implement | achieved. Moreover, in such a structure, since there are few fixing structures and fixing members, there exists an advantage which is a structure with easy size reduction. For the same reason, the number of parts and assembly man-hours (manufacturing man-hours) can be reduced, and there is an advantage that cost reduction can be achieved.

  In the illumination light source 10, the screw head of the screw 21 (a part of the screw 21) is exposed to the outside from the translucent panel 11, but the screw head of the screw 21 is exposed to the outside from the support member 13. You may do it. That is, the screw 21 only needs to be exposed to the outside of the illumination light source 10 from at least one of the translucent panel 11 and the support member 13.

  By the way, the said through-hole is formed when the screw hole 11b, the screw hole 12b, and the screw hole 13b connect. Therefore, in the manufacture of the illumination light source 10, in order to increase productivity, in order to form a through hole, the alignment between the translucent panel 11 and the housing 12 and the housing 12 and the support member 13 are performed. Positioning is important.

  Thereby, in manufacture of the light source 10 for illumination, the position of members can be match | combined easily, without using a jig etc. Since the through hole can be easily formed, the illumination light source 10 with high productivity is realized. In addition, in the light source 10 for illumination, if at least one of the positioning structure of the translucent panel 11 and the positioning structure of the support member 13 is provided, the effect which improves productivity will be acquired.

  In addition, when the members constituting the outer casing of the illumination light source 10 are fixed together by a fixing member such as the screw 21, a waterproof mechanism (dust-proof mechanism) can be easily realized. is there.

  As described above, when the sealing member 15 is sandwiched between the translucent panel 11 and the housing 12, the waterproofness (dustproofness) between the translucent panel 11 and the housing 12 is enhanced. Similarly, when the seal member 19 is sandwiched between the support member 13 and the housing 12, the waterproof property between the support member 13 and the housing 12 is enhanced. Similarly, the waterproofness between the cable seal member 18 and the housing 12 is enhanced by providing the cable seal member 18.

  In addition, the sealing member does not need to be provided over the entire circumference between the members like the light source 10 for illumination, and may be provided only in a place where it is desired to improve waterproofness.

Further, the plate-shaped metal fitting 120 has elasticity and is urged in a direction sandwiching the translucent panel 11, the housing 12, and the support member 13.

  Therefore, if the end 120a is inserted into an opening (not shown) provided in the translucent panel 11 and the end 120b is inserted into an opening (not shown) provided in the support member 13, the light transmission The panel 11, the casing 12, and the support member 13 are fixed together by a plate-shaped metal fitting 120.
