Abstract

The present invention relates to a LED illuminating system used for 3LCD projecting systems, comprising a cooling device, LED driving and controlling circuit boards, collimation components, tricolor light emitting diode LEDs, tricolor LCD panels, and a light splitting and combined prism X-Cube. Three types of light emitting diode LEDs of red, green and blue are respectively arranged on the cooling device, the LED driving and controlling circuit boards; each LED illuminates a corresponding LCD panel through a collimation component; each LCD panel is arranged in a fixed square groove; and the light which penetrates each LCD panel is projected on the display screen for imaging through a projecting system after combining in X-Cube. The present invention is mainly used in 3LCD projecting systems to acquire projecting light sources of high brightness, good uniformity, rich color and good flexibility.

Description

technical field [0001] The invention relates to a high-brightness LED lighting system for a 3LCD projection system. Background technique [0002] In recent years, various LCD projection devices have been more and more used in various fields. The role of the lighting system in the projection device is very important. The success of the lighting system design directly affects the performance index of the device. In general projectors, UHP and UHE discharge high-brightness bulbs are usually used. The advantages are high luminous efficiency and high optical density; make the structure compact. With the substantial improvement in the performance of high-volume LEDs (light-emitting diodes), we have a better choice. LED not only has the characteristics of high efficiency, good monochromaticity, low power consumption, long life, fast response, vibration and shock resistance and no pollution, but also its clear full color gamut and adjustable white balance determine the LED light s...
