Embodiment 2

[0071] In this embodiment, the driving device includes a heating device, and the MEMS micro light-shielding sheet includes an upper layer and a lower layer, wherein the materials of the upper layer and the lower layer have different coefficients of thermal expansion. Other parts are the same as the first embodiment of the transmissive MEMS chip.

[0072] In this embodiment, the driving mode of the driving device is temperature. In practical application, when the heating device heats the materials of the upper layer and the lower layer, since the materials of the upper layer and the lower layer are different, after electrification, it deflects to the side with a smaller expansion coefficient, thereby realizing the bending deformation of the mirror surface of the MEMS micro light blocking sheet. And by controlling the temperature, the bending effect of different MEMS micro-light-blocking mirrors can be realized, so the amount of bending deformation of the MEMS micro-light-blocki...

Embodiment 3

[0074] In this embodiment, the driving device includes an electromagnet, the MEMS micro light-blocking sheet includes an elastic bending piece, and a magnet is fixed on the top of the bending piece. Other parts are the same as the first embodiment of the transmissive MEMS chip.

[0075] In this embodiment, the driving method of the driving device is magnetic force. In actual application, the electromagnet generates electromagnetic force after being energized, which is magnetic, and the magnet on the top of the bending piece is attracted, driving the top of the bending piece to move, causing the bending piece to bend and deform. After the electromagnet is powered off, the magnetism disappears. The bent piece can return to its original shape due to its own elasticity. And by controlling the magnetic force, the bending effect of different MEMS micro light blocking sheet mirrors can be realized, so the amount of bending deformation of the MEMS micro light blocking sheet can be fr...

Description

technical field [0001] The present application relates to the technical field of intelligent lighting, in particular, to a transmissive MEMS chip, a split transmissive chip, a lighting system and an automobile. Background technique [0002] MEMS (Micro-Electro-MechanicalSystem), or micro-electromechanical system, refers to a controllable micro-mechanical structure system composed of semiconductor materials or other materials suitable for micro-processing. The transmissive MEMS chip can use a simple optical system to achieve a very high light source utilization rate, and its array scheme is very suitable for the illumination of the overall surface light source. [0003] Among them, in the field of automobile lights, the far and near lights of automobiles are designed to adapt to different illumination levels and visibility at various speeds. In other words, when the road conditions are poor at night, the speed of the vehicle is slow, or when meeting with the other vehicle; o...
