The invention discloses a rearview mirror with an automatic dimming function, and the rearview mirror comprises a mirror surface main body part, a shell and a support and further comprises at least one light sensor and control equipment; the light sensors detect changes of ambient light and feed back information to the control equipment, and the control equipment adjusts the reflectivity of the mirror surface main body part in an electric control mode according to the information, wherein the mirror surface main body part comprises an absorption type polarizing layer, a dimming layer and a reflecting layer, and the control equipment is connected with the dimming layer and is used for electrically controlling and adjusting the change of the polarization state of polarized light passing through the dimming layer. The rearview mirror disclosed by the invention can automatically prevent glare, and is short in response time and high in safety.

    本发明公开了一种具有自动调光功能的后视镜,其包括镜面主体部分、壳体和支架,还包括至少一个光传感器和控制设备,光传感器探测环境光的变化并反馈信息至控制设备,控制设备根据信息电控调节镜面主体部分的反射率,其中镜面主体部分包括:吸收型偏光层、调光层和反射层,其中控制设备与调光层连接并电控调节通过调光层的偏振光的偏振状态的变化。本发明公开的后视镜可自动防眩光,且响应时间短,安全性高。
