Patent ID: 7985006

Claim:
A light source device, comprising: a circuit member defining a plurality of spaced through holes; a plurality of light emitting diode assemblies having a first side and a second side opposite to the first side, each light emitting diode assembly passing through a corresponding through hole and electrically connected to the circuit member; a heat dissipation component contacting the first side, spaced from the circuit member and configured to dissipate heat generated by the plurality of light emitting diode assemblies; and an optical component contacting the second side and configured to distribute light emitted from the plurality of light emitting diode assemblies; wherein each light emitting diode assembly comprises a dielectric member, a heat conduction member, and a light emitting diode chip; a groove is defined in each dielectric member; one side of the heat conduction member passes through the dielectric member and is exposed to the groove; another side of the heat conduction member contacts the heat dissipation component; the light emitting diode chip is received in the groove and positioned on the heat conduction member; wherein the heat conduction member comprises a substrate and a projecting portion extending from the substrate to the groove; the substrate is positioned on the heat dissipation component; the projecting portion supports the light emitting diode chip; and wherein the dielectric member comprises a support portion and a light reflecting portion; the groove is defined in a central portion of the light reflecting portion; the light reflecting portion is received in a corresponding through hole; the supporting portion is positioned on the substrate and encompasses the projecting portion.
