Far-near light lens assembly device with function of preventing chromatic dispersion

Abstract

The invention provides a far-near light lens assembly device with a function of preventing chromatic dispersion. The far-near light lens assembly device comprises a lamp body reflector bow, a luminescent source, a light blocking sheet device, an electromagnetic valve mechanism, a lens and a lens cover, wherein an electromagnetic valve on the electromagnetic valve mechanism is fixed on an electromagnetic valve mounting plate, and a through holes is formed in the electromagnetic valve mounting plate; a cutoff film filter is attached to the inner surface of the lens. The far-near light lens assembly device has beneficial effects as follows: chromatic dispersion can be effectively prevented, the device is simple and compact in structure, and processing and manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of automobile lamps, in particular to an automobile headlight LED headlight. Background technique [0002] Car headlights, also known as car headlights, usually refer to two functions of high beam and low beam. It is also known as the eyes of a car, not only an important part of the appearance of a car, but also closely related to safe driving at night and in bad weather conditions. The current lens group structure is one of the most commonly used optical system structures for automotive headlights. Based on its excellent light-gathering effect and beautiful appearance, it has been widely used in automotive lights. [0003] Application number 201721086493.0, authorized announcement number CN 207350116 U, the patent document titled "Integrated LED headlight with high and low beams for automobiles" discloses a LED headlight for automobiles: "Including reflective bowl, LED chip, lens, sleeve and A heat dissipation asse...

AI Technical Summary

Problems solved by technology

[0004] 1. The production process of low-dispersion glass materials is relatively difficult, and the technology is not particularly mature, resulting in high prices and high costs;

[0005] 2. For the multi-lens solution, every time a lens is added, the corresponding price will increase slightly. At the same time, the added lens will be more difficult to install, because the entire lamp needs to meet certain laws and regulations, and the tolerance brought by assembly, It is very likely that these design requirements cannot be met, and it will increase the weight of the whole lamp, which is not conducive to lightweight design
