Abstract
A high power image projector includes a plurality of rows of spaced-apart cooling fins on the exterior surface of its light source reflector. The cooling fins are offset relative to adjacent cooling fins, thus disrupting the thermodynamic boundary layer of cooling air flowing over the reflector surface with a shroud. Thus the high-power projector can be adequately cooled with cooling air or other gases, without the need for a liquid cooling system.
