A high performance compound reflector and cooling system for use with a projection system having a lamp for emitting light, an ellipsoid reflector for capturing said light from a first focal point of the ellipsoid reflector and focusing said light at a second focal point co-incident with an integrator rod, and a spherical reflector for retro-reflecting light through the first focal point for reflection by said ellipsoid reflector to said second focal point. The shape of the ellipsoid reflector according to the present invention allows the spherical element to have a larger diameter at the interface between the ellipsoid and sphere. This provides a location for an air deflector in a shape similar to the back of the ellipsoid for channeling air over and outside of the ellipsoid and then along the inside of the sphere. The design of the reflector and air deflector allow cooling requirements to be substantially reduced.
In a projector having a lamp for emitting light, an ellipsoid reflector for capturing said light from a first focal point of the ellipsoid reflector and focusing said light at a second focal point co-incident with an integrator rod, a spherical reflector for retro-reflecting light through the first focal point for reflection by said ellipsoid reflector to said second focal point, the improvement comprising conforming the shape of said ellipsoid reflector and spherical reflector for channeling air over and outside of the ellipsoid reflector and along the inside of the spherical reflectors,
