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.
Claims11
A luminaire comprising:
- (a) a reflector for receiving a lamp and having an opening through which the reflector is adapted to reflect light received from said lamp,
- (b) a closure of light-transmitting material removably fixed to said reflector in a position to cover said opening, the closure being removable from said opening to afford access to said lamp so as to permit relamping,
- (c) an electric circuit within said luminaire through which said lamp is energizable,
- (d) a pair of separable disconnect contacts connected within said electric circuit, the contacts being separable to preclude energization of said lamp via said electric circuit, and
- (e) actuating means operable to effect engagement of said disconnect contacts in response to mounting of said closure in a position to cover said opening and operable to effect separation of said disconnect contacts in response to removal of said closure from said opening, said actuating means comprising a plunger having electrical insulating properties disposed between the light-transmitting material of said closure and one of said disconnect contacts when the closure is in place over said opening.
