Abstract
A projector optic assembly is disclosed for use with various light emitting sources to collect direct the rays of light into a high gradient beam pattern. The projector optic assembly includes a light pipe and a projector lens. The light pipe is segregated into several regions including a reflecting region, a funneling region and a transition plane separating the two regions. At the first end of the reflecting region, closest to the light emitting source, is a connecting lens. At the second end of the funneling region is an emitting aperture that is designed to refract light into the high gradient beam pattern.
