Abstract

A lighting apparatus contains a main housing; a reflector disposed within the main housing, and having a front side and a rear side; a heat conducting body comprising at least two heat pipes, wherein a first portion of the at least two heat pipes are parallel to a central axis of the lighting apparatus on the front side of the reflector, and a second portion of each of the at least two heat pipes is in the rear side of the reflector and is thermally coupled to the main housing; a heat conducting head located on the front side of the reflector, and is thermally coupled to the heat conducting body; at least two light-emitting diodes ('LEDs') thermally coupled to the heat conducting body, and being positioned to face the front side of the reflector so that light emitted from the LEDs are directed to said front side.
