Luminaire power switch

摘要

A novel means for reducing the maintenance costs of cobra head lighting fixtures is presented, comprised of a new housing with a hinge at one end that allows the upper half of the housing to be lifted up for easy access to the lamp and ballast. There is a contact pressure switch in the enclosure which is opened electrically when the upper housing is lifted so that power to the entire enclosure is cut for the safety of the installer. The combination of the switch and the liftable upper housing reduces the steps necessary to do a bulb replacement.

主权项

1. A lighting enclosure and power switch system, the system comprised of a cobra head discharge lamp lighting fixture and an electrical switch,
the lighting fixture comprised of a fixed lower housing and a rotatable upper housing, said lower housing comprised of an interior socket structure with a lamp or light bulb mounted in said socket structure, said rotatable upper housing attached to said lower housing at one end by a rotatable connection means, the connection means oriented such that the upper housing can be flipped up for easy access to the interior of the lower housing, the interior of said lower housing possessing a passive electrical switch that controls the power to the entire lighting fixture, the switch placed on the inside surface of the lower housing, the switch possessing a pushbutton on its upper surface that opens and closes the switch electrically, the upper housing possessing a contact point projecting downwards from the interior surface of said upper housing such that when the upper housing is closed and mated with the lower housing said contact point presses on the pushbutton, which action closes the passive electrical switch providing power to the lighting fixture, the power to the lighting fixture cut upon opening the lighting fixture by lifting the upper housing around the rotatable connection means, which action releases pressure on the pushbutton, which opens the switch electrically.
