  • Apparatus for providing emergency and night lighting
    Patent number: 6045232
    Abstract: An apparatus for detecting failure of a power source and providing illumination of an area upon detection of the failure of the power source. The apparatus for providing emergency and night lighting includes a detection switch connected to the power source for detecting a voltage at terminals of the power source, an alternate power source and an emergency light connected between the detection switch and the alternate power source. The detection switch is operable between a first open position disconnecting the emergency light from the alternate power source upon detection of a voltage at the terminals of the power source and a second closed position connecting the emergency light to the alternate power source and causing the emergency light to illuminate upon detection of an interruption of the voltage at the terminals of the power source. A second light is connected directly to the power source for providing illumination to an area when a voltage is detected at the terminals of the power source.
