Abstract

The invention provides a color wheel module, a light source system and a projection system. The color wheel module includes a color wheel, a color wheel housing and a heat dissipation module. The color wheel includes a color wheel disc with a wavelength conversion material. The heat dissipation module includes The fan, the first heat dissipation assembly and the second heat dissipation assembly; the inside of the color wheel housing has an air circulation channel, the color wheel, the fan and the first heat dissipation assembly are arranged in the air circulation passage, and the second heat dissipation assembly is arranged in the color wheel housing outside, and the second heat dissipation component is thermally connected with the first heat dissipation component; wherein, the airflow generated by the fan blows to the color wheel along the direction parallel to the color wheel, and blows to the first heat dissipation component along the airflow circulation channel to pass through the first The heat dissipation component and the second heat dissipation component conduct the heat generated by the color wheel to the outside of the color wheel housing, thereby improving the conversion efficiency of the color wheel and prolonging the service life of the color wheel, light source system and projection system.

Description

technical field [0001] The invention relates to the technical field of projection, and more specifically, to a color wheel module, a light source system and a projection system. Background technique [0002] For projection equipment, the color wheel in the projection equipment is an essential part of separating and processing colors. After the excitation light emitted by the light source is incident on the color wheel, different wavelength conversion materials on the excitation color wheel generate different colors of the stimulated light, such as red, green and blue. Synthesize a beam of light and perform image projection display. [0003] However, in the process of excitation of the wavelength conversion material by the excitation light, a part of the energy of the excitation light will be converted into heat by the wavelength conversion material, and the color wheel itself has high dustproof requirements, so the color wheel will be sealed in the color As the heat accumu...
