Patent ID: 7806554

Claim:
A LED direct-plugging type multi-chip high power light source comprising a heat dissipating substrate, a protective rubber ring mounted at the front side of the heat dissipating substrate and a raised truncated cone set in the middle of the heat dissipating substrate, the protective rubber ring having a circular hoop shape, and an electroplated coating set at the internal wall surface of the protective rubber ring, a number of LEDs mounted on the surface of the truncated cone and in the protective rubber ring, the LEDs being divided into a number of groups and each group being connected to each other in series, the heat dissipating substrate being provided with two through holes penetrating its front side and rear side, in each of the two through holes separately provided with a pin connected to the LEDs via conductors, one end of the pin inserted into the through hole and the other end of the pin led out from the rear side of the heat dissipating substrate to outside of the heat dissipating substrate, the part of the pin inserted in the through holes being separated from the heat dissipating substrate by a insulator.
