Abstract
A wavelength conversion module includes a driving assembly, a wavelength conversion substrate, and a clamping element. The driving assembly is connected to the wavelength conversion substrate to drive the wavelength conversion substrate to rotate around a central axis of the driving assembly. The clamping element is attached to the wavelength conversion substrate along the central axis. At least one of the wavelength conversion substrate and the clamping element includes at least one recess and at least one through hole. A direction of the through hole is parallel to the central axis, and the clamping element, the recess, and the wavelength conversion substrate define at least one heat dissipation channel. The through hole is relatively adjacent to the central axis and is in communication with the heat dissipation channel.
