The present invention transforms existing electrical wall outlets into an
emergency lighting system for homes, hospitals, hotels, nursing homes and
businesses. The lighting device, designed as a replacement electrical
wall outlet or receptacle, simply plugs into an existing dual outlet
after removal of its faceplate. The lighting device continues to function
as an electrical outlet, however, also comprises a local power source
such as a constant charge lithium ion battery; a motion sensor for
initiating a low level of lighting for darkened room or corridor transit;
a power sensor for activating a high level of light when electrical
service is disrupted, thereby broadcasting a wash of light over an
otherwise darkened room or corridor; and a photoelectric cell which
detects daylight or otherwise provided lighting of the room or corridor
and thereby prevent unnecessary power usage.
