Abstract
The present invention provides an optical device comprising one or more heat pipes with a desired level of thermal coupling with the light-emitting elements which are positioned along a periphery of the evaporator surface portion of the heat pipe in such a way that they are thermally coupled to the heat pipe. In one embodiment, the heat pipe of the present invention can be readily integrated with optical elements such as reflectors or collimators.
