Abstract
A wavelength conversion module, including a substrate, a wavelength conversion member, and a fixing ring, is provided. The substrate has an annular groove. The wavelength conversion member is disposed in the annular groove of the substrate. The fixing ring is disposed on the substrate and is configured to press on an inner region and an outer region of the annular groove and a portion of the wavelength conversion member to expose another portion of the wavelength conversion member and fix the wavelength conversion member on the substrate. In addition, a projection device, applying the wavelength conversion module, is also provided. The wavelength conversion module of the present invention and the projection device applying the wavelength conversion module have better structural reliability and assembly flexibility.
