Projector illumination system

摘要

The present invention includes a projector illumination system having a light source positioned between a condenser lens and a light-collecting reflector. The light source includes a bulb that is urged under compression against a surface of the condenser lens. The condenser lens receives a flow of cooling air over a surface opposite that against which the light source is in contact to minimize deformation of the condenser lens caused by heat emanating from the light source.
