High-efficiency automotive light reinforcing lens

Abstract

The invention discloses a high-efficiency automotive lamplight reinforcing lens. The high-efficiency automotive lamplight reinforcing lens is a solid lens and comprises an incident surface, a fourth refraction curved surface allowing light to be emitted out, an upper reflection curved surface and a lower reflection curved surface, wherein the upper reflection curved surface and the lower reflection curved surface are located between the incident surface and the fourth refraction curved surface and allow light to be reflected in the lens; along the direction of incident light, the upper reflection curved surface and the lower reflection curved surface are both of a symmetrical structure and are connected with each other; the upper reflection curved surface and the lower reflection curved surface protrude in the direction away from an incident light path; and the fourth refraction curved surface protrudes in a light emitting direction. According to the invention, the lens is arranged to be solid, the curvature of each reflection surface and the curvature of each refraction surface are adjusted to form a triangular light type, so the irradiation height of light passing through the lens is higher, the effective range of light radiation can reach 200 m far, illumination width can reach eight-lane width, the lens can well adapt to complex road conditions, and the driving safety of vehicles is improved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a high-efficiency automotive lighting reinforcement lens. Background technique [0002] In order to drive safely in dark conditions, all cars are equipped with headlights at the front. The high beam in the car headlights can improve the line of sight and expand the observation field of view. However, the existing high beam has a narrow illumination width and a low illumination height, which cannot meet certain complex road conditions and is likely to bring safety hazards, so it needs to be solved urgently . Contents of the invention [0003] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a high-efficiency vehicle light reinforcement lens, which is installed in front of the high beam light source, and all the light emitted by the high beam light source first passes through the first refraction lens. When the curved surfac...
