Electric light-emitting apparatus

Claim 1

A light-emitting apparatus, comprising: an electrically conductive substrate with a predetermined number of recesses each having a flat bottom, smooth vertical side walls and an oblique reflection plane of smooth surface, said oblique plane forming an obtuse angle with the flat bottom, an insulated substrate supporting said electrically conductive substrate; a plurality of light-emitting diodes having two electrodes each, one said diode secured on the bottom of each of said recesses and one electrode thereof being electrically connected to said bottom; a plurality of transparent light-conductive resin wafers, one said wafer tightly embedded in each of said recesses and surrounding said light-emitting diode to form a light reflecting face by which the light emitted from the light-emitting diode is reflected by "total reflection phenomenon" to radiate outwardly; one wire connecting the other electrode of each of said light-emitting diodes to a connecting tab on said insulating substrate; and a mask having light-diffusing regions of roughened face and positioned to cover all the abovementioned parts, said lightdiffusing regions being positioned over each light-conductive resin wafer with a predetermined gap therebetween such that said roughened faces of light-diffusing regions receive light from each said reflection plane, and further emit the light outwardly.
