Patent ID: 7741651

Claim:
A light emitting diode comprising: a base having a top surface and formed with a recessed portion indented from said top surface, said recessed portion having a bottom wall surface having a periphery, and a side wall surface extending upwardly from said periphery of said bottom wall surface to said top surface of said base and cooperating with said bottom wall surface to define a receiving space; a light emitting chip provided in said receiving space and disposed on said bottom wall surface of said recessed portion such that a geometric center of said light emitting chip coincides with that of said bottom wall surface of said recessed portion, said light emitting chip having a top chip surface disposed below said top surface of said base, and a peripheral chip surface extending downwardly from said top chip surface to said bottom wall surface of said recessed portion to extend substantially parallel to said side wall surface of said recessed portion, said peripheral chip surface being along at least one segment thereof uniformly spaced from said side wall surface by a predetermined gap; and a wavelength converting layer filled in said receiving space in said recessed portion so as to cover said top chip surface and said peripheral chip surface of said light emitting chip; whereby light emitted through said peripheral chip surface is substantially dissipated within said gap for minimal effect upon light emitted through said top chip surface.
