High/low beam regulating system for automotive laser lighting

Abstract

The invention discloses a high / low beam regulating system for automotive laser lighting, which comprises a laser, an optical switch, a controller, a low-beam lamp optical system and a high-beam lamp optical system, wherein lasers emitted by the laser are output to the optical switch after being coupled by an optical fiber, and then under the control of the controller, the optical switch can respectively output the input lasers to the high-beam lamp optical system and the low-beam lamp optical system, thereby realizing exterior lighting; and the laser is used for providing a blue exciting light source. Through taking lasers as an automotive light source, the system disclosed by the invention has various advantages of laser lighting, for example, the illumination is stronger, the light type can be controlled precisely, quickly and safely, the system is more energy-saving, the design on the system is free, and the like; meanwhile, through adopting the optical fiber for carrying out light guide, the light source can be placed in a position at which the light source is convenient to reject heat, install and maintain, so that the system has high flexibility in the design on interior structures; and a low-beam lamp and a high-beam lamp share a set of laser through the system, so that the interior space and the cost are saved.

Description

technical field [0001] The invention relates to a lighting adjustment system for vehicles, in particular to a far and near light adjustment system for laser lighting for vehicles. Background technique [0002] Automobile high beam and low beam are important parts of automobiles, which provide the necessary lighting and instructions for driving. At present, traditional automobile lighting often uses halogen headlights and xenon headlights. In recent years, LED headlights have also become more and more LED headlights are becoming more and more popular. In addition to saving power and having a longer lifespan, LED headlights have many comparative advantages. From the perspective of trends, it is the general trend for LEDs to completely replace halogen or xenon. However, due to the high power density of the chip, the existing LED light source is easy to generate a lot of heat. It needs a series of heat dissipation design to ensure its normal operation, and the heat dissipation s...

Problems solved by technology

However, due to the high power density of the chip, the existing LED light source is easy to generate a large amount of heat. It needs a series of heat dissipation design to ensure its normal operation, and the heat dissipation system is connected with the light-emitting chip, resulting in the following problems: 1. Usually heat dissipation The system works in the sealed state of the lamp body, which is not conducive to the rapid export of heat and affects the heat conduction efficiency; 2. The heat dissipation system usually has a large structure and takes up a large space, which is not conducive to the structure and aesthetic design of the lamp body
