Led light source far and near light integrated car light module

Abstract

The invention discloses an LED light source far and near beam integrated car lamp module, comprising a low beam light source, a low beam concentrator, a high beam light source, a reflector and a convex lens, and the low beam light source is arranged on the low beam concentrator At the optical origin of the tail end, the front end of the low-beam concentrator is provided with a light-emitting surface, and the light-emitting surface is provided with a cut-off line forming a line for the low-beam light shape, and the convex lens is arranged in front of the light-emitting surface. Below the afterbody of the low-beam concentrator, a high-beam light source and a reflector are provided, and the reflector includes some ellipsoidal reflection bowls, and openings are provided on the top and the front of the ellipsoidal reflection bowl, and the high-beam light source is arranged on At the first focus of the ellipsoid reflective bowl, the second focus of the ellipsoid reflective bowl is set on the cut-off line forming line, and the focus of the convex lens is set on the cut-off line forming line. The present invention seamlessly connects far and near light shapes, is not prone to wear and tear failure problems, and has high comprehensive performance and optical efficiency of the module system.

Description

technical field [0001] The invention relates to a vehicle lamp module, in particular to a vehicle lamp module integrating far and near beams of an LED light source. Background technique [0002] In recent years, concentrators have been used more and more in automotive lighting modules. Concentrators have many optical advantages, such as much smaller volume than traditional reflectors, and higher optical efficiency than reflectors. In addition, concentrators The optical device can integrate many optical elements into one body, which can simplify some parts of the car light module and simplify the structure of the car light module. As an optical part of a car light module, the reflector also has its unique advantages. For example, the light shape formed by the reflector is more uniform and the chromaticity is better, and when it is used as an optical part of the high beam, the far The cohesion performance of the superposition of light beam shape and low beam beam shape is bet...
