Abstract
Embodiments disclosed herein provide optical systems utilizing photon conversion materials in conjunction with a light source and an LED. An LED can be positioned in a cavity defined by a base and one or more sidewalls. Phosphors can be disposed on the entrance face of a lens between the entrance face to the lens body and the LED so that light emitted from the LED will be incident on the phosphor and down converted before entering the lens body through the entrance face. The lens can positioned so that the phosphors are separated from the LED by a gap.
