Abstract

A wavelength conversion device, adapted for converting the wavelength of an incident illumination beam, includes a substrate and a wavelength conversion component. The wavelength conversion component is disposed on the substrate and includes a wavelength conversion layer and at least two wavelength conversion spoilers. The at least two wavelength conversion spoilers are disposed on the wavelength conversion layer, protrude from the wavelength conversion layer, and expose part of the wavelength conversion layer, and the height of each of the at least two wavelength conversion spoilers is less than half of the distance between the at least two wavelength conversion spoilers. The wavelength conversion device in the disclosure has good heat dissipation efficiency. A projector including the wavelength conversion device is further provided in the disclosure. Manufacturing methods of the wavelength conversion device are further provided in the disclosure.
