LIGHT EMITTING DIODE MATRIX ABSTRACT OF THE DISCLOSURE 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 strate- gically 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.
