ABSTRACT:
This luminaire comprises a reflector for receiving a lamp, an opening in the reflector through which light from the lamp is reflected, and a closure removably secured over the opening. Within the luminaire is an energizing circuit for the lamp, and connected within this circuit is a pair of disconnect contacts that are separable to preclude energization of the lamp via the energizing circuit. Actuating means for the disconnect contacts is operable to effect separation of the contacts in response to removal of the closure from its normal position covering the opening. This actuating means includes a plunger of electrical insulating material disposed between the light-transmitting material of the closure and one of said disconnect contacts.
