Light panel illuminated by light emitting diodes
First Claim
1. A light fixture illuminated by light emitting diodes, comprising:
- a generally flat planar panel formed of translucent material having sufficient opacity for the transmission of light, said panel having a front surface, a back surface, and opposed peripheral side edges;
a plurality of high brightness light emitting diodes disposed along at least one of said peripheral side edges in longitudinally spaced apart relation for transmitting light into said panel;
a layer of reflective material on at least said back surface of said panel to facilitate reflection and dispersion of light that occurs within said panel through its said front surface;
a frame surrounding said outer peripheral side edges of said panel and enclosing said light emitting diodes;
said light emitting diodes electrically connected with a low voltage direct current rectifier or driver that is connected with standard household alternating current to rectify and supply polarized constant direct current to the light emitting diodes;
wherein light from said light emitting diodes is transmitted into the panel material from at least one of said peripheral side edges and reflected internally therein causing the light to be emitted through said front surface under the influence of internal reflection.

Abstract
A flat planar light fixture formed of a translucent panel with suitable opacity for the transmission of light is illuminated by a plurality of high brightness LEDs disposed along the edges thereof. A layer of reflective material on a back surface of the panel facilitates reflection and dispersion of light that occurs within the panel through a front surface thereof. The LEDs are powered by low-voltage direct current and coupled with an emergency backup battery that is maintained in a charged condition by household current. The light fixture may be operatively connected with a signal receiver that controls the light intensity and turns the LEDs on and off responsive to signals transmitted from a remote signal transmitter. The LEDs may be provided in different colors to allow the user to vary the color of illumination. The light fixture may also be operatively connected with an alarm system.
