LED car headlamps

As the car headlamp in driving safety plays an important role, so LED headlamp is the most difficult and final put into use. Previously, LED headlamps used only in concept car, LED lighting technology as well as the car with the development of industry, LED headlamp application already from concept car, luxury car to midrange car models, and even general transition lighting luminous intensity has reached the level of incandescent lamp.

Automobile lamps including headlights and the lamp. In the night road, headlights illuminated front should ensure that the 100 m, high 2 m place within the scope of the objects, and brightness even, The lamp is not only to ensure that car 40 m the driver can see obstacles, and can't let the oncoming drivers or pedestrians produce glare, to ensure that the car at night when the car is driven rendezvous in safety.

Traditional automobile lamps and the output of two in the function of the beam, and each beam distribution model are in static distribution, and the specific lighting distribution also meet the national standards. But in practical application, the system of the beam in limited distribution from the point of view of the range, in some of the more complex conditions (such as turning) easily to have visual blind area. In addition, the traditional lighting system does not have before automatic adjustment of the distribution of the beam function, the beams and in the transformation between the beam to manual operation, so that to realize the driver in the traffic of the frequent driving environment between vehicles, easy to have the blinding light. In order to overcome the shortcomings of the traditional automobile lamps, adaptive system AFS arises at the historic moment. As before

AFS is a driver can better adapt to all kinds of speed, the types of roads and weather conditions change, improve the driving safety system headlamp. Its principle of work is as follows: when the car into special road conditions (such as corners), due to the steering wheel and speed changed the Angle and speed transmission to the electronic control unit (ECU) signal corresponding changes. ECU capture these signals of change, at the same time judgment into the kind of vehicles corner, and sent out the corresponding instructions to the headlamp control unit, according to the instructions of the control unit receive control into AFS light body internal drive three elements of micro-motor glow around the axis of the rotation, and corresponding in unconventional road and weather road, change the lighting system, provide better security.

As a white LED technology and the development of air dynamics and the demand of automobile modeling the front position more and more low and streamlined, for the space more and more small reserve headlamp. In order to meet the automotive lighting and personalized intelligent demand, AFS and LED lights in combination has become the development trend of modern automobile lamps.
