Patent ID: 7939919

Claim:
An LED light bar having a plurality of LED-packaging arrangements on a circuit board, wherein the LED-packaging arrangements include: a) a first connection block; b) a second connection block; c) a light-emitting chip positioned at the top of the first connection block and via connection wires electrically coupled to the first and second connection blocks; d) a positioning/packaging body adapted to enclose the first and second connection blocks in position such that the bottom surfaces of the first and second connection blocks are exposed; and e) a transparent packaging body adapted to seal and fix the light-emitting chip and the connection wires in position for an optimal protection, and wherein the circuit board includes an isolation carrier plate with circuits at the top thereof, and wherein the circuits are arranged corresponding to the first connection blocks and the second connection blocks of the LED-packaging arrangements in such a way that a plurality of first connection pads and second connection pads are created, and wherein a plurality of heat-dissipating pads are formed at the bottom of the isolation carrier plate, and wherein a heat-conducting through hole is formed between corresponding ones of the first connection pads and heat-dissipating pads for a thermal connection.
