Light emitting diode

A light emitting diode comprising:

• a base having a top surface and formed with a rectangular 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 and perpendicularly 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, 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 by a predetermined gap from said side wall surface of said recessed portion, said gap surrounding said peripheral chip surface of said light emitting chip;
• 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.

A base adapted for a light emitting diode that includes a light emitting chip having a top chip surface and a peripheral chip surface extending from the top chip surface, and that further includes a wavelength converting layer, said base comprising:

• a base body 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;
• said receiving space being configured for receiving the light emitting chip therein such that said bottom wall surface of said recessed portion receives the light emitting chip thereon in a manner that a geometric center of the light emitting chip coincides with that of said bottom wall surface of said recessed portion, such that said top surface of said base body is disposed above the top chip surface of the light emitting chip, and such that said side wall surface of said recessed portion is substantially parallel to and forms a predetermined gap with the peripheral chip surface of the light emitting chip, the peripheral chip surface of the light emitting chip thereby being along at least one segment thereof uniformly spaced from said side wall surface by said gap;
• said receiving space being adapted to be filled with the wavelength converting layer to cover the top chip surface and the peripheral chip surface of the 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.
