Abstract

A high power LED lamp comprises a cover; a base panel; an LED mounted on the base panel which further includes an insulator; a substrate; a power supply received in the insulator; and a heat sink device disposed between the cover and substrate; wherein the insulator is engaged with the heat sink device, and both the LED and base panel are defined above the heat sink device. In accordance with the present invention, the heat created during work of the LED can be radiated rapidly via the heat sink device and thus ensuring good heat dispersion, high brightness, long life and low temperature.

Claims
