Methods and apparatus for providing a projection system (10). In one embodiment, the system provides plurality of light sources (12) collimating light using a parabolic concentrator (54). The system may direct light from a plurality of light sources (12) towards a light collector (60) which directs light towards a Fresnel lens (62) which directs light to a polarizing recombiner (80). The system may also usiethe recombiner to allow light having a first polarization to pass. The recombiner (80) to convert light of a second polarization to light having the first polarization and letting converted light pass to an LCD image panel. In another embodiment, a projection system (10) having a light source capable of achieving a bright, homogenized output is disclosed. The present invention provides such a projection system (10) through at least two embodiments. The first projection system may use a cubic projection system. The second may use a conical projection system.
