Fluorescent wheel, double-color laser source and laser projection equipment
The disclosure provides a fluorescent wheel, including a fluorescent region and a transmission region; the fluorescent region has fluorescence powder for emitting fluorescence under excitation by excitation laser; and the transmission region is for transmitting laser; the fluorescent wheel is for diffusing at least laser to be transmitted. Using fluorescent wheel to diffuse laser enables laser transmission meanwhile removing speckles by diffusion, sparing a separate speckle-removing component, improving light processing efficiency of fluorescent wheel. The disclosure also provides a double-color laser source using the fluorescent wheel, and a laser projection equipment including the double-color laser source, which can output three-primary-color light via fluorescent wheel component, meanwhile removing speckles for double-color laser, thereby reducing usage of optical components, and lowering complexity of optical architecture of double-color laser source, contributing to miniaturization of laser projection equipment. The disclosure is applied in the field of laser illumination display technologies.
