The latest Mazda LED headlight technology analysis

LED matrix headlamps due to cost issues have been the Mercedes Benz BMW these high-end car exclusive. With the maturity of LED technology, some Japanese manufacturers began to develop and manufacture more LED matrix headlamps cheap, Mazda is one of the manufacturers in the. In 2014 CEATEC JAPAN (CEATEC), Mazda demonstrated a new technology ALH LED array Adaptive Headlights ". The technology is designed to use a more simple and inexpensive way to manufacture and popularize adaptive LED headlamps. Let us work together to understand the new LED headlamps technology.

A simpler structure of adaptive LED array headlamps

Mazda ALH adaptive LED array headlight structure is more simple. It includes the ALH light module, the wide area, the four part of camera and image recognition. The four parts are combined together to realize the functions of precise illumination, enlarging the illumination area and the automatic adjustment of the optical axis.

Anti glare and increased irradiation range

Have the experience of driving at night should have such a friend. If you turn on the headlights of the car or the rear car, you can't see the road because of the high light. Therefore, as a qualified driver, should be at the right time to turn off the high beam to prevent the glare of other drivers caused by high beam. Mazda ALH LED array adaptive headlamps to identify the vehicle through the image recognition technology of vehicle headlight. In the detection of the car has always been / front car, through the closure of the corresponding LED light group, to achieve the function of high beam glare.

Mazda ALH LED array adaptive headlamps in addition to accurate lighting functions to achieve a high beam, with the optical axis with the speed adjustment and wide area lighting the two more practical function.

Simple but low cost

Because of cost considerations, Mazda simplifies the structure and control circuit of matrix type LED beam, so it can not achieve accurate lighting LED luminance of the light-emitting element is more complex and accurate control. In contrast, Audi's camera image recognition system is more powerful, in addition to the identification of lights, but also to identify pedestrians. The difference between the above two points, making Audi matrix LED headlamps with more complex and perfect lighting. Of course, Mazda's solution has great advantages in price.
