Patent ID: 8684550

Claim:
A light source comprising: a heat-dissipating plate disposed on a base substrate; a heat-dissipating pin protruding from and continuously extending from the heat-dissipating plate, wherein a first end of the heat-dissipating pin opposite a leading end of the heat-dissipating pin continuously extends from the heat-dissipating plate, wherein the heat-dissipating pin extending from the heat dissipating plate forms a substantial L-shape, wherein the heat-dissipating plate on the base substrate is a first leg of the substantial L-shape, and the heat dissipating pin is a second leg of the substantial L-shape, the second leg of the substantial L-shape extending into a hole formed in the base substrate; a heat-dissipating layer including a first portion disposed between the base substrate and the heat-dissipating plate forming the first leg, a second portion disposed on a bottom exterior surface of the base substrate, and a connecting portion extending into the hole in the base substrate, wherein the connecting portion connects the first portion to the second portion and is disposed on a sidewall of the base substrate and in contact with the heat-dissipating pin forming the second leg; a light emitting chip for emitting light; a housing surrounding the light emitting chip, the housing having a receiving space spanning from a top surface to a bottom surface of the housing, wherein the heat-dissipating plate is disposed on the bottom surface of the housing, wherein the light emitting chip is disposed on the heat-dissipating plate exposed by the receiving space, and the light emitting chip makes contact to the heat-dissipating plate; a first solder disposed on a corner edge of the heat-dissipating plate and on the first portion of the heat-dissipating layer to connect the corner edge of the heat-dissipating plate to the first portion of the heat-dissipating layer; and a second solder connecting an end portion of the heat-dissipating pin to the connecting portion of the heat-dissipating layer in the hole of the base substrate and the second portion of the heat-dissipating layer.
