There's a problem. Therefore, the discharge lamp 3 and the connector 5 are electrically connected to each other, and then the connector 5 and the igniter 6 are electrically connected to each other, so that the discharge lamp 3 and the connector 5 are electrically connected to each other. If not, the connector 5 and the igniter 6 are not electrically connected to each other, the voltage from the controller 4 is cut off from the voltage supply path supplied to the igniter 6, and the igniter 6 is disconnected. It is intended to prevent the generation of high voltage and to ensure safety.

In particular, in this embodiment, the igniter storage portion 23 is provided at the rear portion of the reflector 2 so that the outer surface and the inner surface of the front opening 20 of the reflector 2 are flush with the outer surface and the inner surface of the igniter storage portion 23. Since it is integrally provided so that there is no cut portion, the molding die can be easily removed, and the reflector 2 and the igniter storage portion 3 are also provided.
The intensity of

Further, in this embodiment, the connector 5
When attached to the igniter 6, the back surface 54 of the connector 5 and the back surface 62 of the igniter 6 are flush with each other, so that the appearance is improved. Moreover, since the connector 5 is provided with the concave portion 53 for the knob, the rear surface 54 of the connector 5 is
Even if the rear face 62 of the igniter 6 is flush with the connector 5, the connector 5 can be easily attached to and detached from the igniter 6 by hanging a finger or the like on the recess 53. Furthermore, since the igniter 6 and the igniter housing portion 23 are provided with the cord escape grooves 63 and 24, the rear surface 5 of the connector 5
4 and the back surface 62 of the igniter 6 are flush with each other,
The cord 40 between the controller 4 and the connector 5 can be wired along the grooves 63 and 24, and there is no possibility of causing any trouble in terms of appearance and wiring.
