Abstract
A high-power LED lamp comprises a cylindrical housing having a cavity and an open end with the housing made of a heat conductive material. One or more high power LEDs are mounted within the cavity such that at least some of the light from the LEDs is directed out the open end of the housing. An encapsulating material fills the cavity and surrounds the LEDs with the encapsulating material providing a waterproof covering over the LEDs and at least partially transmitting light from the LEDs out the opening. Heat from the LEDs conducts away from the LEDs and through the encapsulating material and the housing to dissipate in the ambient around the lamp.
