Abstract:
1. A lighting device having a power sensor for sensing a disruption in a main power supply, the lighting device comprising: at least one light emitting diode (LED) in electrical communication with corresponding electrical circuitry; a local electrical energy source for supplying electrical energy to said at least one LED; an LED drive circuit/boost converter; a control circuit in electrical communication with said at least one LED, said LED drive circuit/boost converter, and the power sensor, wherein upon sensing the disruption in the main power supply the power sensor signals said control circuit to engage said LED drive circuit/boost converter and, thus, operatively engage said at least one LED to illuminate; and a reflector positioned proximate to said at least one LED for reflecting light provided by said LEDs.
