The light process of present embodiment is put 10 and is comprised light source 101, optics synthin 102, light source brightness adjusting device 103, spectral module 104 and digital light processing module 105.

Light source 101 comprises multiple sub-light source for sending different color light, such as can comprise red-light source, green-light source, blue light source wherein two or more, also can comprise the sub-light source of other color.Light source such as can adopt LASER Light Source or LED light source.

Optics synthin 102 is positioned on the output light path of light source 101, receives multiple coloured light of sending of light source 101, by multiple coloured light with become the first polychromatic light and export.

Light source brightness adjusting device 103 is positioned on the output light path of optics synthin 102, for receiving the first polychromatic light that optics synthin 102 exports, the first polychromatic light being adjusted to the second polychromatic light of distributing with certain brightness degree and exporting.

Digital light processing module 105 is positioned on the output light path of spectral module 104, receives the light beam of multiple colors that spectral module 104 exports, and modulates rear output to the light beam of multiple color.

Red, green, blue three sub-light sources are comprised with light source 101, and the brightness figure place of the light beam of each color is that 8 (in other words, the light of each color all has 2 in the light (i.e. the light beams of multiple colors of digital light processing module 105 output) exported for light processor 10 8individual brightness degree), light source brightness adjusting device 103 receives the first polychromatic light that optics synthin 102 exports, and regulates the first heterogeneous light brightness.Such as, the brightness degree of red, green, blue three sub-light sources is 255, light source brightness adjusting device 103 can periodically by the first heterogeneous light brightness with such as 1,2,4,8,16,32,64,128 brightness degree distribution the second polychromatic light.Spectral module 104 is exported to after the second polychromatic light of brightness regulation.Spectral module 104 receives the second polychromatic light that light source brightness adjusting device 103 exports, and is broken down into the light beam of multiple color.Digital light processing module 105 receives the light beam of multiple colors that spectral module 104 exports, and modulates rear output to the light beam of multiple color.
