Abstract

The invention relates to an LED array high- and low-beam bifunctional module system and belongs to the technical field of LED automotive lighting techniques. The LED array high- and low-beam bifunctional module system comprises a radiator, an LED source PCB (printed circuit board), a primary optical element, a cut-off line retainer, a lens support and a lens. The primary optical element in the system can provide reshaping and homogenizing for LED source array high and low beams; the overall structure of the system is simplified; module assembly is facilitated; optical energy utilization rate is increased for the system; therefore, the system has less burden of heat dissipation.

Description

technical field [0001] The invention relates to the technical field of LED vehicle lamp lighting, in particular to an LED array dual-function module system for far and near light. Background technique [0002] LED headlight lens modules have been widely used in high-end models due to their advantages such as compact structure, small size, and flexible design of lens size according to the shape requirements of car lights. With the maturity of LED module technology, LED lens modules will become the mainstream trend of automotive headlights. One of the primary optical components is an important optical component in the LED module of automotive headlights, and the requirement to achieve dual functions of far and near light has increased once. Difficulty in designing optical components. [0003] Most of the primary optical elements in the dual-function LED far and near light module adopt a reflective far and near light integrated structure or a refractive far and near light two-...
