Abstract
The present disclosure provides a wavelength conversion device, and its light source system and projection system. The wavelength conversion device includes a wavelength conversion material layer, and a first light-filtering layer on a first side of the wavelength conversion material layer. The wavelength conversion device also includes a first thermally-conductive dielectric layer configured between the wavelength conversion material layer and the first light-filtering layer. The first thermally-conductive dielectric layer has a thermal conductivity greater than or equal to the wavelength conversion material layer, and has a refractivity less than the wavelength conversion material layer. Accordingly, the heat generated by the wavelength conversion material layer may be timely conducted out, thus improving the conversion efficiency of the wavelength conversion device.
