MEMS intelligent illumination system for automobile lamp, automobile lamp assembly and automobile

Abstract

The invention relates to the technical field of automobile lamps, in particular to an MEMS intelligent illumination system for an automobile lamp, an automobile lamp assembly comprising the MEMS intelligent illumination system for the automobile lamp and an automobile comprising the automobile lamp assembly. The MEMS intelligent illumination system for the automobile lamp comprises a light source and an MEMS pixel array; light emitted by the light source is transmitted through the MEMS pixel array and then is emitted out; the MEMS pixel array comprises a plurality of supporting bases which are provided with light transmitting channels and are distributed in an array mode; and an MEMS micro-blocking piece and an MEMS micro-blocking piece driving circuit are movably arranged on each supporting base, wherein the MEMS micro-blocking pieces can open or close the light transmitting channels, and the MEMS micro-blocking piece driving circuits drive the MEMS micro-blocking pieces to move on the supporting bases. The MEMS intelligent illumination system, the automobile lamp assembly and the automobile have the advantages that each MEMS micro-blocking piece driving circuit independently controls the swinging frequency of the corresponding MEMS micro-blocking piece on a single pixel point, and therefore the gray level of the emitted light can be adjusted, the pixel is high, the dimming precision is high, the size is small, the operation reliability and stability are good, and the integration degree is high.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a MEMS intelligent lighting system for automobile lights, an automobile lamp assembly including the MEMS intelligent lighting system for automobile lamps, and an automobile including the automobile lamp assembly. Background technique [0002] Car light is an important component of a car. It provides lighting for the driver when driving at night or in a tunnel, so that the driver can see the road ahead clearly, thereby ensuring driving safety. [0003] With the development of the automobile industry, the lighting system of automobile lights is becoming more and more intelligent, which can meet various lighting needs. However, the current intelligent car lighting system has the defects of high optical power loss, low pixel size, large volume, and no gray scale adjustment. For example, the matrix type headlamp in the prior art can realize intelligent lighting, but has low ...

AI Technical Summary

Problems solved by technology

However, the current intelligent car lighting system has the defects of high optical power loss, low pixels, large volume, and no grayscale adjustment.

For example, the matrix headlights in the prior art can realize intelligent lighting, but the pixels are low and the volume is large, so it is difficult to realize the miniaturization of intelligent lamps

DLP (Digital Light Processing, digital light processing) technology can realize high-pixel lighting of lamps and lanterns, but its complex optical system will cause huge loss of optical power, and the utilization rate of light sources is low
