Abstract
The present invention is a low power and low heat dissipating, low illumination system that is based in an electrical box cover plate, preferably in a light switch cover plate. It allows for the maintenance of an electrical bleed current through the fluorescent light controlled by that light switch so as to keep a minimal thermal differential between the unlit and lit light. The light switch cover plate has a series of imbedded LEDs that illuminate an area all around the light switch. The unit is retrofittable on conventional light switches.
Claims18
A low level illumination system comprising:
- a switch cover plate adapted for housing an electrical light switch having at least one lens formed by a blind ended orifice formed on a back surface thereof said switch cover plate;
- a chamber formed about a periphery of said orifice extending from said back surface;
- a means for providing a bypass electrical bleed current comprising a U shaped printed circuit board having at least having at least four light emitting diodes, eight resistors, four 0.01 to 0.1 μF capacitors, a 1 amp/400 watt diode and a plurality of interface wires disposed thereon so as to form an array of electrically connected components that has a one watt power profile in parallel electrical configuration with said electrical light switch with at least one light emitting diode affixed to a face thereof said means;
- at least two wires forming an electrical connection between the low level illumination system and a light switch power supply;
- wherein said means for providing a bypass electrical bleed current is engaged with said back surface such that said LED is positioned adjacent said chamber such that at least a portion of light emitted from said light emitting diode is received within said chamber and dispersed through said lens to illuminate an area on and around said switch cover plate.

A low level illumination system comprising:
- an electrical outlet cover plate for partially receiving and housing an electrical power outlet having at least one lens formed by a blind ended orifice formed on a back surface thereof;
- a chamber formed about a periphery of said orifice extending from said back surface;
- a means for providing a bypass electrical bleed current to any electrical device connected to said electrical outlet having at least one light emitting diode affixed thereto and mechanically connected to said back surface;
- said means for providing a bypass electrical bleed current comprising a U shaped printed circuit board having at least having at least four light emitting diodes, eight resistors, four 0.01 to 0.1μF capacitors, a 1 amp/400 watt diode and a plurality of interface wires disposed thereon so as to form an array of electrically connected components that has a one watt power profile;
- at least two wires forming an electrical connection between the low level illumination system and a power supply;
- wherein said means for providing a bypass electrical bleed current is engaged with said back surface such that said LED is positioned adjacent said chamber such that at least a portion of light emitted from said light emitting diode is received within said chamber and dispersed through said lens to illuminate an area on and around the outlet cover plate.
