German manufacturers to work together to develop a new type of LED headlight system

Drivers often need to switch lights. Driving on the highway when the need to light in the city; the low road, on both sides of the shadows or sidewalks need lateral light wider; the fog fog lamp switch to country; lack of street lights need the appropriate lights; their vehicles and cars between the distance change is to change the lights. If these switches can occur automatically, and has always been driving the car does not feel dazzling, but also to increase their own clear vision driving, is bound to increase road safety, especially to reduce accidents at night.

Sponsored by the German Federal Ministry of Education (BMBF) project, is to solve the above problems. This project is composed of LED (OSRAM Licht AG) giant OSRAM leading German car factory, Daimler (Daimler AG), Germany's most famous scientific research institutions Fraunhof Association (Fraunhofer-Gesellschaft), Germany Hella Hooke automotive electronics (HELLAKGaAHueck&Co.) and Germany (Infineon Technologies Infineon chip maker AG) each provide a unique contribution.

The new LED headlights many features lasted three and a half years of research and development, the project through the road test and production levels. Successfully create intelligent, high resolution adaptive headlights (Adaptive Forward Lighting).

According to the data, two headlights of each of the three LED light source, each LED light source has 1024 controllable lights (Light Point), which is a pixel (Pixel). Smart headlights can be accurately matched with a variety of traffic conditions and weather conditions, it will not stimulate the direction of the car to drive the eyes, because the vehicle sensors can continue to help analyze the surrounding traffic conditions.

Comparison of the new generation of LED headlamp for vehicles

Currently on the market adaptability of LED (Adaptive Headlight) is composed of several side by side and stacked up. The current design requires additional electronic components to switch lights. Because of the limited area of the headlight area, this design leads to an increase in the number of LED components that can not be increased, while also taking into account the issue of thermal efficiency.

In contrast, the new design is a new and efficient chip is responsible for starting LED. As a result, in the limited head space, but can achieve a higher resolution, which is more accurate, more intelligent car lighting. In addition, OSRAM special lighting department developed LED module, its electrical interface and thermal interface can be connected directly to the vehicle's electronic system, and more efficient than the traditional way, can be said to be a breakthrough.

Secondly, the conversion in different lighting conditions when the smooth, for example a headlamp, headlight switch, do not need to complete the mechanical actuator (Mechanical Actuator), only need to operate electronic system. OSRAM technical director Stefan Kampmann said: we want to continue to develop this new high-resolution LED light source, do a good job in mass production (Serial Production). This LED product has great potential in the use of car headlights".

The above is the prototype of the German Academy of science and technology alliance LED headlight system, the former is lit, the latter is off the state.

LEDinside pointed out that the new controller is also Germany's Infineon Technologies build, their team and Fraunhof, association, OSRAM, Mercedes-Benz, Mercedes-AMG, smart and other well-known brands of the German automaker Daimler, jointly created a new LED car to meet European market demand and regulations with headlight system, inspiration for the industry and the subsequent effect will be quite positive.
