Abstract

The invention discloses a projection lighting system and projection equipment. The projection lighting system comprises a plurality of light source devices, a light combining device, a vibration speckle eliminating device, a compound eye light homogenizing device, a relay device, a light beam control device, a reflection imaging device, a polarization compensation device and a projection device, and the relay device is used for adjusting the irradiation area of the whole light beam; the light beam control device is used for transmitting the light beam to the reflection imaging device; the reflection imaging device reflects the light beam to obtain a reflection light beam with image information; the light beam control device is further used for transmitting the reflected light beams to theprojection device for corresponding projection. Through the polarization characteristic of the laser light source, the light spot size of the illumination light beam is reasonably controlled; the reflection imaging device can utilize all the polarized light beams to realize a projection lighting system with higher light source utilization rate, and high-contrast projection can be realized by screening the light beams entering the projection device in combination with the polaroid, and the contrast can be improved by more than 150%.

Description

technical field [0001] The present invention relates to the field of projection display, in particular to a projection lighting system and projection equipment. Background technique [0002] LCOS (Liquid Crystal on Silicon, liquid crystal on silicon or liquid crystal on silicon) display device is a new type of reflective projection display device, which is a liquid crystal display device that uses semiconductor silicon technology to control liquid crystal and then "projects" a color picture. Compared with transmissive LCD (Liquid Crystal Display) and DLP (Digital Light Processing) display devices, LCOS display devices have the advantages of high light utilization efficiency, small size, high aperture ratio, mature manufacturing technology, etc., and can easily achieve high resolution rate and full color performance. Because the LCOS display device has the above-mentioned advantages, the LCOS display device has great advantages in the future large-screen display application ...
