  • Emergency lighting system
    Patent number: 4323820
    Abstract: There is disclosed an emergency lighting system which is capable of distinguishing between a loss of power due to the opening of a line switch, and a loss of power resulting from a line failure when the switch is closed. A secondary power source powers the light in the event of a line failure. Thus when the line switch is open, i.e., when emergency lighting is not necessary, the light is not powered by the secondary source.
