Abstract

The present invention discloses a wavelength conversion device and a light source and relates to the technical field of light sources, and the problem of low heat radiation efficiency of the wavelength conversion device in the prior art can be solved. The wavelength conversion device of the invention comprises a driver and multiple blade-shaped wavelength conversion substrates which are circumferentially distributed on the driver. The multiple wavelength conversion substrates and the driver are fixed. The driver can drive the multiple wavelength conversion substrates to rotate around the driving shaft of the driver. The wavelength conversion device also comprises laser irradiation regions which are distributed on the multiple wavelength conversion substrates, and at least a part of the laser irradiation regions is coated by a fluorescent material. Along the axial direction of the driving shaft, the projections of the laser irradiation regions on an axial vertical plane are closed patterns. The invention can be used for the wavelength conversion device.

Description

technical field [0001] The invention relates to the technical field of light sources, in particular to a wavelength conversion device and a light source. Background technique [0002] At present, the laser light source in the laser projection equipment usually uses a single-color or two-color laser to excite the wavelength conversion material to generate fluorescence other than the laser color, thereby forming RGB three primary colors to provide illumination for the back-end opto-mechanical part. Therefore, a wavelength converting device with a wavelength converting material is an important component in a laser light source. [0003] figure 1 It is a wavelength conversion device in the prior art, including a substrate 01 and a driving device 02 for driving the rotation of the substrate 01, the substrate 01 includes a fluorescent area (not shown in the figure) and a transmissive area (not shown in the figure), the The fluorescent area is coated with a fluorescent material 0...
