Abstract

The invention provides a laser source, a light source mode switching method and a laser projection apparatus. The laser source comprises: a laser for generating a laser beam; a fluorescent wheel for receiving the laser beam and emitting fluorescence in at least one color; a color filter wheel rotating synchronously with the fluorescent wheel and including first and second color filter plates arranged radially along the color filter wheel; a light path guide component arranged on a light path between the fluorescent wheel and the color filter wheel and used for guiding the fluorescence in at least one color to the first or second color filter plate, wherein the first color filter plate is used for receiving the fluorescence in at least one color and outputting light of first spectral width,the second color filter plate is used for receiving the fluorescence in at least one color and outputting light of second spectral width, and the first spectral width is greater than the second spectral width. Applicability of the laser source is improved.

Description

technical field [0001] The invention relates to the field of laser projection display, in particular to a laser light source, a light source mode switching method and laser projection equipment. Background technique [0002] With the continuous advancement of science and technology, laser projection devices appear more and more in people's home entertainment and work due to their advantages such as wide color gamut and high color purity. [0003] Currently, in a laser projection display device, a monochromatic laser plus a fluorescent wheel and a color filter wheel are usually used to obtain the three primary colors of red, green, and blue. Specifically, monochrome lasers usually use blue light, and the fluorescent wheel includes at least a red light conversion zone, a green light conversion zone, and a light source transmission zone. Correspondingly, the red light conversion zone is provided with a red light conversion material, and the green light conversion zone is provid...
