Self-adaptive high-low-beam integrated LED multi-module headlamp

Abstract

The invention provides a self-adaptive high-low-beam integrated LED multi-module headlamp. The headlamp comprises a high-low-beam following self-adaptive light type control system, a light compensation system and a color temperature control system; the high-low-beam follow-up self-adaptive light type control system comprises an LED light source module array which comprises a plurality of LED light source modules, more than two parallel LED light source modules of which the optical axes are parallel to the center of an automobile body form a straight driving light source, and more than one LED light source module arranged outside the straight driving light source forms a steering light source, wherein the included angle formed between the optical axis of each LED light source module and the center of the automobile body is an acute angle; the included angles formed between the optical axes of the LED light source modules of the steering light source and the center of the automobile body are sequentially increased from inside to outside. According to the self-adaptive high-low-beam integrated LED multi-module headlamp, due to the fact that multiple independent LED light source modules are arranged to serve as the headlamp, when an automobile straight drives or turns, high-low-beam light spots during straight driving and light type following during turning are achieved by controlling the different LED light source modules to be lighted to obtain the better illumination angle.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an adaptive far and near beam integrated LED multi-module headlamp. Background technique [0002] Automobile headlights are an important part of the automobile lighting system, providing active safety protection for automobile driving. High-power white light LED (Light Emitting Diode) is gradually developing into a new generation of green light source for automobile headlights due to its advantages of small size, high luminous efficiency, fast response, energy saving, environmental protection and stable structure. LED light source is used to replace traditional light source. It is an inevitable trend in the development of automobile headlight technology. [0003] Affected by the 360-degree light emission of traditional light sources, traditional headlights have a low light utilization rate and are prone to glare. In order to improve the lighting flux, it is often necessary to add a supplemen...

Problems solved by technology

Although there are also headlights based on the adaptive system AFS (Adaptive Front-lighting System) in the traditional light source headlight system, it mainly adjusts the irradiation direction of the lamp head up and down, left and right during driving through the follow-up rotation technology, or through Different light types produced by different light-cutting devices, the above two methods mainly realize adaptive lighting through mechanical means, there are many shortcomings in terms of functions, and the degree of intelligence is not high
