Self-adjustment filtering anti-dazzle device

Abstract

The invention discloses a self-adjustment filtering anti-dazzle device, comprising a filtering screen and a lighting board, wherein the filtering screen comprises a frame and a light changing board, the light changing board is arranged on the frame, the light changing board is composed of a plurality of light changing units which are arranged in the array mode, a light changing control device is arranged in the frame, all the light changing units of the light changing board are connected with the light changing device, the lighting board is composed of a plurality of photosensitive elements which are arranged in the array mode, and all the photosensitive elements of the lighting board are connected with the light changing control device. According to the self-adjustment filtering anti-dazzle device, the plurality of light changing units which are arranged in the array mode are arranged on the filtering screen, the plurality of photosensitive elements which are arranged in the array mode are arranged on the lighting board, the lighting board can collect the light intensity distribution of a current area, the filtering screen can adjust the light transmittance according to the light intensity distribution which is measured by the lighting board, the light intensity after the light penetrates through the filtering screen is in accordance with that before the light penetrates through the filtering screen, a problem of too dark caused by the whole adjustment of the filtering screen is avoided, the definition of the view of a driver is guaranteed, and the probability of the occurrence of road accidents is reduced.

Description

technical field [0001] The invention relates to a light filtering and anti-glare device, in particular to an automatically adjustable light filtering and anti-dazzle device.
