Multiple Positioned Light Source to Achieve Uniform or Graded Illumination

Abstract

An integrated and modular lighting system is disclosed. The lighting system includes a plurality of modules, each module including at least two echelons of light emitting diodes and a power supply on a common substrate. The modular lighting system is used to provide uniform illumination of an enclosed display stand.

1 .- 15 . (canceled) 
     
     
         16 . A light emitting diode package comprising:
 a light emitting diode encased within a clear epoxy packaging material, the light emitting diode connected to two metal leads coming out of the epoxy packaging; and   a zener diode placed within the epoxy packaging, said zener diode connected electrically parallel to the light emitting diode.   
     
     
         17 . A light emitting diode circuit comprising:
 a light emitting diode mounted on a substrate; and   a zener diode connected parallel to said light emitting diode and also mounted on the substrate.   
     
     
         18 . A light emitting diode circuit recited in  claim 17  wherein the zener diode is connected in electrically reverse bias relative to electrical bias of the light emitting diode.
