Light leakage prevention automobile lamp electromagnet

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of car lamp electromagnets, and particularly relates to an anti-light leakage car lamp electromagnet. Background technique [0002] At present, the control of far and near light of automobile headlights is usually realized by electromagnets. The traditional electromagnets of automobile lights only pass the light source refracted by the fluorescent cup to the lens, which will cause the problems of light leakage and inconcentration of light source refraction; The car lamp electromagnet usually uses a reset spring to control the locking position of the visor, which is mostly complicated in structure and inconvenient for promotion and application. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the primary purpose of the present invention is to provide a light-leakage-proof electromagnet for a car lamp, which can ensure no light leakage, so that the emitted light source is more concentr...

Problems solved by technology

[0002]At present, the far and near light control of automobile headlights is usually realized by electromagnet. There are problems of light leakage and non-concentrated refraction of the light source; in addition, the existing car light electromagnets usually use return springs to control the locking position of the visor, and most of them have complex structures, which are not easy to promote and apply
