Concentrating led bifocal lens module

Abstract

The invention relates to a light-concentrating type LED dual-light lens die set. The light-concentrating type LED dual-light lens die set comprises a radiator, a light source assembly mounted on the radiator, a light barrier assembly and a lens assembly, wherein the light barrier assembly and the lens assembly are mounted at the front part of the radiator; a first circuit board of a near LED die set of the light source assembly is mounted on a first mounting surface of the radiator, and a reflecting mirror with a free-form surface is mounted at the upper part of the radiator; rays emitted by a neat LED light source are reflected to a focal spot O in the lens by the reflecting mirror to be collected, and then ejected to the lens through a light barrier so as to form a near dead line light type; a second circuit board of a distance LED die set is mounted on a second mounting surface of the radiator, and a light condenser is mounted at the front part of the radiator through a light condenser bracket; and rays emitted by the distance LED light source are totally reflected to the focal spot O in the lens through the light condenser to be collected, and then ejected to the lens so as to form a distance light type. The light-concentrating type LED dual-light lens die set disclosed by the invention is compact in structure, can improve the precision of the distance light type and the near light type, and well solves the problems that dead lines spray color light, the distance light and the near light are out of alignment in focusing, and the distance light is uneven.

Description

technical field [0001] The invention relates to a concentrating LED double-light lens module, which belongs to the technical field of automobile lighting fixtures. Background technique [0002] LED light sources have the advantages of energy saving, environmental protection, high brightness, and long life, and are widely used in the automotive industry. Among them, LED headlights are a hot research field for new car lights. Due to its unique shape and compact structure, headlights with integrated far and near beams are receiving more and more attention. However, the far and near beam integrated lens module composed of high-power LED light sources, the light passes through the light barrier and the lens to form a low beam light pattern and a high beam light pattern to meet the vehicle lighting requirements. However, the existing far and near beam integrated lens modules have fatal defects such as coloring of the cut-off line of the near and far beams, misalignment of the far...
