Single-light lens assembly for automobile

Abstract

The invention relates to a single-light lens assembly for an automobile. The single-light lens assembly comprises a resin lens, a plastic support, an upper beam and lower beam switching module, an aluminum reflector and an H1 halogen lamp, wherein the resin lens is installed at the front end of the plastic support, the plastic support is installed right ahead of the upper beam and lower beam switching module, the upper beam and lower beam switching module is placed right ahead of the aluminum reflector, a light outlet of the aluminum reflector and the resin lens are arranged in a coaxial mode in the same direction, the H1 halogen lamp is installed at the bottom of the aluminum reflector, the plastic support and the resin lens are tightly pressed through buckles, and the aluminum reflector is fixed by the plastic support through four supporting legs. According to the single-light lens assembly, upper beam and lower beam switching can be automatically achieved through the adjustment of a light barrier; the single-light lens assembly is simple in structure, stable in performance and low in cost; the aluminum reflector and the lens are good in combination effect, wide in light range and clear, and cost is further reduced and effects are good due to the adoption of the H1 halogen lamp.

Description

technical field [0001] The present invention relates to the technical field of automobile lamps, and more specifically, the present invention relates to a single vision lens group for automobiles. Background technique [0002] In the prior art, the automobile headlight adopts the refraction principle of convex mirror light to form an image, and it uses a magnifying glass and a microscope to observe objects that should be magnified near the observer. Make the 45° line on the light baffle as required by the low beam regulations (the light and dark cut-off line requirements of the low beam in GB4599 "Automotive Headlight Light Distribution Performance"). The reflector is made into an ellipse to diffuse the light from the halogen bulb, and the light pattern is emitted through the light baffle. Now it is very common for lamps to make patterns on BMC (unsaturated epoxy resin) reflectors. Through the principle of light bulbs, relying on the principle of refraction and reflection o...

Problems solved by technology

In order to realize the functions of high beam and low beam, dual high beam and low beam lamps are usually used in the prior art, which cannot automatically change the high beam and low beam, and the structure is more complicated and the cost is higher
