  • OPTICALLY ENHANCED LIGHT CONVERTER
    Publication number: 20230375820
    Abstract: Provided is a light converter and its method of manufacture. A light conversion layer containing light conversion particles in a binding material is provided for generating emission light from excitation light incident on the light conversion layer. A planarization layer is disposed on a surface of the light conversion layer. At least one optical coating is part of or on a surface of the planarization layer that is relatively smooth in comparison with the surface of the light conversion layer.
    Type: Application

  • Enhanced wavelength conversion device
    Patent number: 10802386
    Abstract: A wavelength conversion device comprises: a substrate; a reflective resin layer on the substrate; and a wavelength conversion layer on the reflective resin layer, configured to receive incident light and to provide output light by wavelength conversion of the incident light, such that the output light is reflected by the reflective resin layer. A method for manufacturing a wavelength conversion device by applying a reflective resin layer to a substrate and providing a wavelength conversion layer on the reflective resin layer is further provided.
