Abstract

The invention belongs to the technical field of intelligent lighting and relates to a biaxial array reflection type MEMS chip and a lighting system comprising the biaxial array reflection type MEMS chip. The biaxial array reflection type MEMS chip comprises a plurality of MEMS micromirrors distributed in an array mode and a plurality of MEMS micromirror driving circuits; the MEMS micromirrors reflect projection light; the MEMS micromirror driving circuits are connected with the MEMS micromirrors in a one-to-one correspondence mode and drive the MEMS micromirrors to independently rotate around the transverse axes or the longitudinal axes, perpendicular to the projection light, of the MEMS micromirrors. Each MEMS micromirror can be driven by the corresponding MEMS micromirror driving circuit to realize double-axis rotation, so that the mirror surface direction of each MEMS micromirror can be changed; light emitted by a light source is projected to the MEMS micromirror array and is reflected by the MEMS micromirror array to be emitted out to form an illumination light pattern; the mirror surface direction of each MEMS micromirror can be changed, so that the up-down height or the left-right position of the illumination light pattern can be changed, and therefore, up-down dimming and left-right dimming functions are achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent lighting, in particular to a biaxial array reflective MEMS chip and an illumination system comprising the biaxial array reflective MEMS chip. Background technique [0002] At present, intelligent lighting has developed towards the trend of high pixelation, and the best one is DLP (Digital Light Processing, digital light processing) headlights. DLP headlights use DMD (Digital Micromirror Device, digital micromirror device) chip as the key executive component, and use reflection to perform pixelated lighting, which can realize high-pixelated intelligent lighting. The DMD chip is a MEMS micromirror array chip. Its working principle is: when the micromirror does not receive the working signal, the micromirror stays in the non-projection position and is in the "off" state; when the micromirror receives the working signal, the chip Deflected to the working position, it is in the "open" state. That...
