Title:
COLOR WHEEL MODULE, LIGHT SOURCE MODULE, AND PROJECTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/114303
Kind Code:
A1
Abstract:
A color wheel module, light source module, and projector system. The color wheel module comprises a color wheel and a drive device driving the color wheel to rotate, and the color wheel comprises a transparent substrate (10), and multiple light emitting modules (110, 111, 112, 113) and multiple light filtering modules (120, 121, 122, 123) fixed to a surface of the transparent substrate (10). The multiple light emitting modules (110, 111, 112, 113) join to form an annular light emitting layer, the multiple light filtering module (120, 121, 122, 123) join to form an annular light filtering layer, and the light filtering layer is located on an inner side or an outer side of the light emitting layer. The light emitting modules (110, 111, 112, 113) comprise a first substrate layer (1100) in contact with the transparent substrate (10) and at least one functional layer (1102) on a surface of the first substrate layer (1100). The light filtering modules (120, 121, 122, 123) are disposed in one-to-one correspondence with the light emitting modules (110, 111, 112, 113), to adjust light beams emitted from the corresponding light emitting modules (110, 111, 112, 113). In this way, the present invention can reduce holder components used to fix light filters, thus simplifying a structure of a color wheel module, and improving heat dissipation performance of the color wheel module.
