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).
Claims19
A light converter, comprising:
- a light conversion layer, comprising light conversion particles in a binding material, for generating emission light from excitation light incident on the light conversion layer;
- a planarization layer on a surface of the light conversion layer;
- and
- at least one optical coating as part of or on a surface of the planarization layer that is relatively smooth in comparison with the surface of the light conversion layer.
The light converter of claim 10, wherein the second surface of the light conversion layer is opposite the first surface of the light conversion layer.
An optical device, comprising:
- a substrate;
- and
- a light converter in accordance with any preceding claim, on the substrate.
A method of manufacturing a light converter, comprising:
- depositing a planarization layer on a surface of a light conversion layer, the light conversion layer comprising light conversion particles in a binding material and generating emission light from excitation light incident on the light conversion layer;
- and
- applying at least one optical coating to or forming at least one optical coating in a surface of the planarization layer, the surface of the planarization layer being relatively smooth in comparison with the surface of a light conversion layer.
