Abstract:
This is an emergency lighting system that provides an emergency driving voltage to drive at least one lamp when the AC power input to the lamp is detected as absent. A rechargeable battery pack and recharging circuit are contained in a first modular housing, and driving circuitry is contained in a second modular housing. An easily accessible, manually-operable service switch disables the provision of battery power to the driving circuitry (when the switch is in the open state), thereby allowing substantial reduction in installation time and cost. A test switch is included to emulate power failures. A transmitter and receiver mechanism allow a user to remotely disable the provision of battery power to the driving circuitry, thereby offering battery power conservation, if the emeregency lamplight is not needed. Likewise, a photo-sensing mechanism disables the provision of battery power to the driving circuitry, if there is sufficient ambient light.
