Vehicle-borne sun sensor

The invention provides a vehicle-borne sun sensor comprising a base and a top cover arranged on the base. The top cover comprises a bottom plate and a light-transmissive portion arranged in the middleportion of the bottom plate, and the light-transmitting portion is parabolically raised upward to form a fisheye structure. The vehicle-borne sun sensor has the advantages that a photosensitive areais enlarged through a fisheye-shaped top cover design, and the sensor is more sensitive and effective to light. At the same time, according to the trapezoidal shape of the top cover, the non-directionality during installation is avoided, and the good fool-proof installation can be achieved. 本发明提供了种车载阳光传感器，包括底座及设置于底座上的顶盖，所述顶盖包括底板及设置于底板中部的透光部，所述透光部呈抛物状向上凸起形成鱼眼结构。本发明的有益效果体现在：通过鱼眼式的顶盖设计，扩大了感光面积，使传感器对光线有更灵敏有效的感应。同时，通过顶盖的梯形形状避免了安装时的无方向性，能起到很好的防呆安装。
