Abstract

The invention provides a device for preventing an automobile rear distant light from dazzling a driver and belongs to the field of electronics. The device can prevent the driver from being disturbed by light of the automobile rear distant light at night and improves running safety and driving comfort.

Description

technical field [0001] The invention provides a device for preventing the high beam of the rear car from being dazzled, which belongs to the field of electronics. The device can help the driver prevent the interference of the high beam light of the rear car when it is dark, and improve driving safety and driving comfort . Background technique [0002] When driving at night, the car behind turns on the headlights, causing light interference to the driver and seriously affecting driving safety. [0003] The above problems can be well solved by using the device, and the cost is greatly reduced due to the use of the optical sensor and LCD technology. Contents of the invention [0004] The purpose of the present invention is to provide a technology based on the optical sensor to detect strong light, dynamically adjust the light transmittance of the LCD, thereby adjusting the reflection amount of the rearview mirror, and prevent glare. On the mirror, through the automatic phot...
