ABSTRACT:
Light emitting diodes in a substantially semispherical form having an outer shell-like region of semiconductor material of one conductivity type and a subsurface body of semiconductor material of an opposite conductivity type forming a p-n junction are mounted to a surface of an insulating substrate member extending therefrom to allow a portion of each diode element to protrude past the outer surface of the substrate. Metallic coatings are provided on both the outer shell-like semiconductor material having one conductivity and a second metallic coating is provided on the subsurface body semiconductor material having a second conductivity for electrical contact. A transparent conductive material is further disposed over the diode structure connecting diodes formed in an array.
