A vehicle lamp lens device

Abstract

This utility model discloses a vehicle headlight lens device, including a faceplate, a rear shell, a lens unit, a light source, and a widening structure. The faceplate and the rear shell together form a receiving cavity. The lens unit, the light source, and the widening structure are disposed within the receiving cavity. The lens unit includes a straight lens and a light-incident plate. The straight lens includes a first arcuate convexity, a second arcuate convexity, and a third arcuate convexity that are arcuately convex in a direction away from the light-incident plate and are connected to each other. Light emitted from the light source is emitted outward through the straight lens, the widening structure, and the faceplate. This application utilizes the first, second, and third arcuate convexities to ensure that light emitted from the three light sources is emitted through the straight lens. The entire arc surface of the straight lens receives light, preventing dark areas from forming. The light then passes through the widening structure to achieve a uniform lighting effect, eliminating any grainy appearance and meeting the requirement for uniform lighting while effectively reducing particle costs.

Description

Technical Field

[0001] This utility model relates to the technical field of vehicle lights, and in particular to a vehicle light lens device. Background Technology

[0002] Most static bending lights on the market now illuminate by reflecting and refracting light through a reflector. When it is necessary to distribute the light to a certain area, multiple LED beads are usually set and the spacing between the LED beads needs to be designed to be relatively large. However, when the spacing between the beads is large, the efficiency of the left and right edges of the reflector is low, which will create dark areas when lit. Simply relying on the outer vertical stripes or the inner diaphragm cannot make the lighting uniform, resulting in a grainy lighting effect. Utility Model Content

[0059] In this embodiment, the widening structure 8 is a vertical stripe or a membrane.

[0060] When the stripes are vertical, they are located on the inner side of the mask 1; specifically, vertical stripes are formed on the surface of the mask 1 during its molding process. When the stripes are diaphragms, they are positioned between the lens unit 3 and the mask 1; specifically, the diaphragm is attached to the inner side of the mask 1. The vertical stripes or diaphragm process the light from the lens unit 3, while the outer vertical stripes or diaphragm ensure uniform illumination, allowing the light to pass through the mask 1 more evenly and thus optimizing the headlight's lighting effect.
