  • Rotatable emergency light with direct drive motor
    Patent number: 7887205
    Abstract: An emergency lighting system comprises a wall unit housing that may readily be located and secured between wall studs in a conventional structure. The housing includes a rotatable door to which an emergency lamp is secured, said door being in a closed position when main electrical power is on such that the lamp is hidden within the housing. The rotatable door is coupled to a motor that is supplied battery power when main electrical power loss is detected, thereby rotating the door to an open position and exposing the emergency lamps. The emergency lamps are also illuminated by battery power.
