Abstract
A light source assembly comprises a light pipe, a first color light source at a first tapered light collector, a second light source at a second tapered light collector, and at least a first dichroic filter operative to pass first color light and to reflect second color light toward a light output port. A light valve may be positioned to receive light from the light pipe. One or more light entrances to the light pipe may have a filter, e.g., a short wave pass filter, oriented in a plane generally parallel to the axial optical pathway.
