Headlight lens module

Abstract

The invention discloses a headlight lens module. The headlight lens module includes a light source, a reflector, a light changing device, a sleeve, a convex lens and a supporting mechanism. The reflector includes a first reflective cup and a second reflective cup, wherein the first reflective cup is fayed to the second reflective cup, and a plurality of aspheric curved surface reflecting surfacesare arranged in the first reflective cup and a plurality of aspheric surface reflecting curved surfaces are arranged in the second reflective cup. The light source belongs to a surface light source formed by a plurality of LED light beads and is arranged on the supporting mechanism and located under the faying surface of the first reflective cup and the second reflective cup, and the length direction of the light source is parallel to the faying surface. The sleeve is connected to the supporting mechanism, the convex lens is arranged on one end of the sleeve opposite to the supporting mechanism, the light changing device is connected with the supporting mechanism and used for switching modes of short-range light or long-range light. Through arrangement of the same-body dual-section reflector, light patterns of the lens module are good, high in brightness, and can meet the national standard, reach or exceed the effect of hernia headlamps of the same power, and utilization rate of lightenergy can be improved.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a headlight lens module. Background technique [0002] With the continuous development and maturity of LED (light-emitting diode) manufacturing technology and the gradual decline in production costs, LED light sources have begun to be widely used in automotive lights, special lighting fixtures, public lighting and other fields, and have huge development potential. The most promising light source in the 21st century. As an essential safety component for automobile driving, automobile lamps play an important role in the active safety of automobiles. LED has the advantages of strong reliability, long service life, high color purity, fast response, small size, easy design, and excellent changes in the appearance of automobiles, making it more and more widely used in exterior lighting. [0003] Due to the low lumen value of LEDs, in order to achieve a higher lumen value ...

AI Technical Summary

Problems solved by technology

The traditional xenon headlight is a point light source, and its light distribution is relatively simple. When the traditional light distribution mode is applied to the surface light source formed by multiple lamp beads, the error is large, and the brightness and light pattern are poor.
