Abstract:
1. A high brightness light emitting diode (LED) emitting light of white or desire color, comprising: a substrate; an epitaxial layer comprising a first-type cladding layer disposed on said substrate, a first active layer emitting light of first wavelength and disposed on said first-type cladding layer, a second active layer emitting light of second wavelength and disposed on said first active layer, and a second-type cladding layer disposed on said second active layer; wherein a material system of said first active layer is selected from a group comprising (Al.sub.xGa.sub.1-x).sub.yIn.sub.1-yP.sub.z N.sub.1-z (0<x≦1, 0<y≦1, 0<z<1); wherein a material system of said second active layer is selected from a group comprising (Al.sub.xGa.sub.1-x).sub.yIn.sub.1-yP.sub.z N.sub.1-z (0<x≦1, 0<y≦1, 0<z≦1); a first electrode disposed on an exposed portion of said first-type cladding layer; a second electrode disposed on said second-type cladding layer.
