ABSTRACT:
Improved collection optics for a lighting system comprised of a light source, reflector and light receptive component include a multi-portion reflector or a non-imaging optical collector having a positive curvature located at an input end to the light receptive component. The collection optics capture additional lumens for transmission through the light guide. The optical arrangement can also collect different colors of light from the source that would otherwise be omitted from transmission through the light receptive component.
