Problems solved by technology

The two-color wheel structure refers to the two-color wheel system of fluorescent wheel + filter wheel. However, synchronous control of the fluorescent wheel and filter wheel is required, which increases the complexity of the light source.
In the single color wheel structure, the color wheel includes the inner ring as the fluorescent area and the outer ring as the filter area. In this structure, there is no need to consider the synchronization of the fluorescent area and the filter area. However, the width of the fluorescent area and the width of the filter area are different in color Superimposed on the radial direction of the color wheel, resulting in a large outer diameter of the color wheel, making it difficult to miniaturize the light source

The invention provides a color wheel component, including the first load; the wavelength conversion element is fixed to the Zhoubi of the first load of the first load, which is used to receive the light source of the light source and generates the laser; the second load part, and what it is described, and the descriptionOne end of the first carrier is fixed; and the filter element is fixed on the second bearing part to receive and filter the laser.The invention also includes the light source device and projection system of the above color wheel components.The rotation control of the color wheel component of the present invention is simple and the size is small.

Description

technical field [0001] The present invention relates to the field of optical technology, and in particular, to a color wheel assembly, a light source device and a projection system. Background technique [0002] At present, spatial light modulators are widely used in the field of projection display. Spatial light modulators generally include LCD, LCOS, DMD, etc. The single-chip spatial light modulator projection system realizes color projection display based on the primary color light of timing switching. Simple structure, low cost and other characteristics, widely used in the low-end market. Since the laser-excited phosphors have a wide range of laser-received spectral bandwidths, filters are usually added to the light source to intercept the desired wavelength band, such as green or red light from yellow fluorescence. [0003] In practical light sources, a dual-color wheel or a single-color wheel structure is generally used to filter the phosphor spectrum. The dual-color...
