Problems solved by technology
This scheme can avoid the problem that most of the lasers incident on the same position of the fluorescent wheel in the previous scheme will increase the thermal load of the fluorescent wheel. After the wavelength conversion material is applied, the duty cycle of the wavelength conversion material is larger, and the heat load increases, so it is necessary to improve

The invention relates to a light source system, projection equipment and a color wheel. The light source system includes a color wheel, an exciting light source, and a supplementary light source. The color wheel includes a scattering area and a wavelength conversion area. Both the scattering area and the wavelength conversion area are ring-shaped, and the scattering area is sleeved on the The outer side or ring of the wavelength conversion area is set inside the wavelength conversion area; the excitation light source is used to emit light to the scattering area and the wavelength conversion area, and the scattering area is used to receive the excitation light source The light is scattered and emitted, the wavelength conversion region is used to convert the wavelength of the received light of the excitation light source to emit the stimulated light, and the supplementary light source is used to emit supplementary light to expand the color gamut of the light source system .
Description
technical field [0001] The invention relates to a light source system, projection equipment and a color wheel. Background technique [0002] Currently, commonly used light sources for projection equipment include white light UHP bulbs, LEDs, laser phosphor light sources and RGB laser light sources. UHP bulbs suffer from short life, poor monochromaticity, and low light utilization. Although the LED light source has a long service life and good monochromaticity, LEDs generally have a current saturation phenomenon, that is, the luminous efficiency decreases significantly with the increase of the driving current; at the same time, the optical expansion of the LED light is large, making the spatial light modulator Once the size is fixed, the number of LEDs that can be accommodated is limited. These two factors lead to low output brightness of projection equipment with LED light sources. [0003] There is a method for semiconductor lasers to excite wavelength conversion materia...
