The invention discloses a light leakage preventing automobile lamp electromagnet, and belongs to the technical field of automobile lamp electromagnets. Comprising a mounting plate, a light shielding plate and an electromagnetic driving mechanism are mounted on the mounting plate, the light shielding plate is hinged to the mounting plate and is in driving connection with the electromagnetic driving mechanism, an arc-shaped light shielding piece is arranged on the light shielding plate, and a light reflecting coating is arranged on the surface of the light shielding piece. Compared with the prior art, the automobile lamp electromagnet has the advantages that firstly, the optical surface roughness Ra of the anti-dazzling screen of the automobile lamp electromagnet is less than or equal to 0.02 mu m, light leakage can be avoided, and an emitted light source can be more intensively refracted to a lens of an automobile lamp, so that the brightness is increased, the range is increased, and high and low beams have a super-bright visual effect; secondly, a limiting upper plate and a limiting lower plate are arranged on the mounting plate, rotation of the light shielding plate can be limited, and the situation that the rotation amplitude of the light shielding plate exceeds a set range is avoided; finally, the device is simple in structure, convenient to install, low in cost and convenient to use and popularize.

    本发明公开了一种防漏光的车灯电磁铁,属于车灯电磁铁技术领域。包括有安装板,所述安装板上安装有遮光板与电磁驱动机构,所述遮光板铰接在安装板上并与电磁驱动机构驱动连接,所述遮光板上设置有弧形的遮光片,所述遮光片的表面设置有反光镀层。与现有技术相比:首先,本车灯电磁铁的遮光片的光学表面粗糙度Ra≤0.02um,能够确保不漏光,也能够使射出的光源更加集中折射到车灯的透镜上,从而增加亮度,提高射程,使得远近光具有超亮的视觉效果;其次,安装板上设置有限位上板与限位下板,能够对遮光板的转动进行限位,避免遮光板的转动幅度超出设定的范围;最后,本发明结构简单、安装方便、成本低,便于使用和推广。
