作が容易にでき、作業性が向上する。Next, the operation of this embodiment will be explained. When the discharge lamp 4 is lit, the heat generated from the lamp 4 is cut off by the socket mount 12 which also serves as a preheater and the support 8, and is radiated by the air passage formed between these, and is then transferred to the lighting device 6. heat transfer is inhibited. Also,
Although the lighting device 6 generates heat from semiconductor switching elements and the like, the heat is dissipated by ventilation in the gap A between the supports 8 and 9, and an excessive rise in temperature is effectively prevented. Furthermore, since the lighting device 6 is mounted on one support 8 with a spacer 11 made of an insulating material and is attached to the other support 9 without contacting it, the lighting device 6 is double-layered by the case 7 and the support 8°9. It forms an insulating structure and can maintain sufficient insulation distance. In this embodiment, one of the supports 8 also serves as a preheater, and
Since the other support body 9 is formed by arranging the back plates,
There is no need to provide a heating element or a back plate, and the number of parts can be reduced, and the main body case 1 of the lighting device 6 can be
This can be done by storing the support 8.9 holding the lighting device through the rear opening 3 of the main body case 1, which facilitates manufacturing and improves workability.
