ABSTRACT:
An integrated circuit chip containing one or more light-emitting diodes is mounted within a light-diffusing encasement having a standard incandescent light bulb lamp base. The integrated circuit chip also contains a rectifier and voltage regulator circuit. The resulting solid state lamp may then be used to replace any standard incandescent light bulb, as it can be inserted in any existing standard A.C. or D.C. lamp sockets. The encasement may be a standard hollow light bulb, or, for maximum light diffusion, a solid transparent or translucent plastic in which the chip is embedded.
