Abstract
A light converter and method of manufacture is provided. A light conversion layer (301), comprising light conversion particles (301a) in a binding material (301b) is provided for generating emission light from excitation light incident on the light conversion layer (301). A planarization layer (304) is on a surface of the light conversion layer (301) and at least one optical coating (305) is part of or on a surface of the planarization layer (304) that is relatively smooth in comparison with the surface of the light conversion layer (301).
