  • Patent number: 7922354
    Abstract: A high performance, high efficiency solid state electronic lighting device, having a sealed fixture body for use outdoors or in environments requiring IP rated sealed fixtures, uses light emitting diodes for producing light from AC current that operates on an as needed basis dependent upon occupancy, ambient light levels and facility load requirements. The high performance, high efficiency solid state electronic lighting device can also be used to replace the internal workings and reflective surfaces of a standard fluorescent fixture, a high-intensity-discharge (HID) lamp, or other arc-based lamps using light emitting diodes for producing light from AC current that operates on an as needed basis dependent upon occupancy, ambient light levels and facility load requirements.
