The light process of present embodiment is put 10 and is comprised light source 101, light source brightness adjusting device 103 and digital light processing module 105.
Light source 101 is LASER Light Source, and for generation of the first coloured light, such as light source 101 can produce the light of white light or other color.Adopt LASER Light Source, one or more advantages having that the light directionality making to send is good, brightness is high, monochromaticity is good etc.
First coloured light for receiving the first coloured light, and is adjusted to the second coloured light of distributing with certain brightness degree and exports by light source brightness adjusting device 103.Light source brightness adjusting device 103 such as can be arranged on the output light path of light source 101.
Digital light processing module 105 is positioned on the output light path of light source brightness adjusting device 103, for receiving the second coloured light that light source brightness adjusting device 103 exports, the second coloured light being modulated to the 3rd coloured light and exporting.In one embodiment, " modulation " can refer to: the light selecting one or more brightness degree from the second coloured light distributed with certain brightness degree, and the photosynthetic of this one or more brightness degree is become the 3rd coloured light.The brightness of the first coloured light is more than or equal to the brightness of the 3rd coloured light.
The brightness figure place of light (i.e. the 3rd coloured light) exported for light processor 10 is 8 (in other words, have 2
8individual brightness degree), light source brightness adjusting device 103 receives the first coloured light that light source 101 exports, and regulates the brightness of the first coloured light.Such as, the brightness degree of the first coloured light that light source sends is 255, and the brightness adjustment of the first coloured light can be periodically with the second coloured light of the brightness degree distribution of such as 1,2,4,8,16,32,64,128 by light source brightness adjusting device 103.Digital light processing module 105 is exported to after the second coloured light of brightness regulation.Digital light processing module 105 receives the second coloured light that light source brightness adjusting device 103 exports, and the second coloured light is modulated to the 3rd coloured light output.Such as, the brightness of the coloured light (i.e. the 3rd coloured light) that light processor 10 exports is 128, and so, the brightness degree that is decomposed into of the first coloured light that light source exports by light source brightness adjusting device 103 is respectively such as 1,2,4,8,16,32, second coloured light of 64,128, and export the second coloured light after brightness regulation to digital light processing module 105.Digital light processing module 105 is modulated the second coloured light, the second coloured light is modulated to the 3rd coloured light that brightness is 128, and is exported by the 3rd coloured light after modulation.
The brightness figure place of the light (i.e. the 3rd coloured light) exported for light processor 10 is equally for 8, because light source brightness adjusting device 103 and digital light processing module 105 only need adjustment 8 times, the brightness of coloured light 0 ~ 255 grade can be realized, and accordingly when adopting PWM, width due to pulse represents corresponding brightness degree, therefore must regulate 2
