Abstract

The invention discloses a high-efficiency vehicle LED high-beam / low-beam integrated double-light lens group. The lens group comprises a low beam source and a high beam source which are fixed on a base, wherein light emitted by the low beam source and the high beam source is emitted from a lampshade at the front end of the base, and a reinforcing lens used for reinforcing the light emitted by the high beam source is installed at the position, where the light source is emitted, of the high beam source. The reinforcing lens for reinforcing a high beam is installed in front of the automotive high-beam source; on the premise that national light pattern standard is met, the lens is set to be solid; and a triangular light pattern is formed by adjusting the curvature of each reflecting surface and the curvature of each refracting surface, so the irradiation height of light passing through the lens is higher, the effective range of light radiation can reach 200 meters, and the illumination width reaches eight lanes; and thus, the lens group 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 LED far and near beam integrated double-light lens group. Background technique [0002] In order to drive safely in dark conditions, all cars are equipped with headlights at the front. In the headlights of the car, the high and low beams are switched to adapt to driving on different road sections. However, the high and low beams in the existing automobile headlights have narrow illumination width and low illumination height, which cannot meet some complex road conditions and are likely to bring safety hazards, so they need 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 automotive LED far and near light integrated bifocal lens group. When switching to high beam, all light emitted by the high beam light source First ent...
