ABSTRACT:
A matrix of light emitting diodes constructed of mosaic sectors each having a predetermined number of light emitting diodes, characterized by the cathode contacts of said diodes being outward, the cathodes being covered by conductors which have holes strategically placed so that the light emitted by said diodes is confined to small high intensity dots; said diodes having conductors positioned to connect to the anodes of said diodes and thermally connected to an anodized aluminum substrate which acts as a heat sink, the outer surface of said cathode conductors being blackened to absorb sunlight, and the exposed surface of said cathodes being nonreflective; a grid of optically and electrically insulative properties isolates and separates said diodes.
