Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0016] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a surface is said to be "opposite" another surface, it means that there is a solid between the two surfaces.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by on...

Abstract

A car lamp structure, the car lamp structure includes a lens and a light source, the lens includes a light-emitting surface, a fixing surface opposite to the light-emitting surface, and a total reflection surface connecting the light-emitting surface and the fixing surface; At least one light-incident structure is recessed from the fixed surface to the light-emitting surface; the light-incident structure has a first light-incident surface, the light-exit surface is flat, and the total reflection surface is composed of a plurality of curved surfaces with different radii of curvature , the first light-incident surface is located at the top of the light-incident structure opposite to the fixing surface and is a D-shaped curved surface protruding toward the fixing surface. The light source is accommodated in the light incident hole and faces the first light incident surface. The lens and the car light structure provided by the invention can directly form oval-shaped light spots that are clear and conform to car light specifications, and can also improve the utilization rate of light.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a lens and a vehicle lamp structure with the lens. Background technique [0002] The light-transmitting mirror holder of the existing car light structure generally cannot directly adjust the light emitted by the car light structure to a preset light pattern. In order to make the light emitted by the car light structure form a clear spot that meets the car light specification, it is usually used to set a reflector in front of the light source to reflect the light in a certain area above the cut-off line required by the car light specification to other areas. Therefore, there are many optical elements that the light needs to pass through, the loss of light is large, and the utilization rate of light is low. Contents of the invention [0003] In view of this, the present invention provides a lens capable of forming a clear light spot conforming to the specifications of ...
