PROJECTION APPARATUS WITH LIGHT SOURCES HAVING COMMON PRISM EXIT OPTICAL PATH

摘要

A projection apparatus is formed employing a prism and a plurality of light sources. The latter are employed to output a plurality of different color light bundles of different wavelengths for the prism. The light sources and the prism are disposed relative to each other in a manner such that the different color light bundles of different wavelengths enter the prism at angles suitable for the respective wavelengths and the prism, for the different color light bundles of different wavelengths to exit the prism on a substantially common optical path.
