Abstract
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.
Claims14
In a display projector having a condenser lens that receives light from an illumination source and directs the light toward an image source to form a projection display image, the improvement comprising:
- an illumination source support that supports the illumination source under compression against the condenser lens surface.
In a display projector having a condenser lens that receives light from an illumination source and directs the light along an axis toward an image source to form a projection display image, the illumination source including an envelope surface through which illumination passes toward the condenser lens, the condenser lens including first and second generally opposed surfaces and the light from the illumination source passes into the first surface and out the second surface, the improvement comprising:
- a cooling system for directing an axial flow of cooling air over the second surface of the condenser lens;
- and
- an illumination source support that supports the illumination source with its envelope surface under compression against a mechanical stop.
