Abstract
A light integrator is provided, the light integrator comprising a body for integrating light, the body having a length and a light egress end. The light integrator further comprises a first light entrance device for accepting light from a first lamp into the body, the first light entrance device comprising a first light entrance face, the first light entrance device located distal the light egress end. The light integrator further comprises a second light entrance device for accepting light from a second lamp, the second light entrance device comprising a second light entrance face, the second light entrance device laterally displaced from the first light entrance device in a direction generally perpendicular to the first light entrance face, such that light from the first and second lamps independently enter the integrator via the first and second light entrance devices respectively, and exit the light egress end. The second light entrance device is further displaced from the first light entrance device along the body towards the light egress end, such that each of the first and second lamps may displaced from one another along the body.
