LED technology is expected to crack the 'chronic disease' of high beam

When driving at night, if the opposite vehicle is on the high beam, then you have to be 120 thousand careful, because the high beam of the vehicle will stimulate your eyes, causing dazzling and dazzling. affect vision. According to the measurement, it takes about two minutes for the vision of the person to move from the bright to the dark, and the reverse dark adaptability time (After the car) Generally, it takes about 10 seconds. During this period of time, it is difficult for eyes to distinguish roads and objects as required, and accidents are easy to occur. Although China's traffic regulations have clear regulations on the use of night lights for motor vehicles. For example, the fifth paragraph of article 48th of the implementation regulations of the Road Traffic Safety Law of the People's Republic of China stipulates that on roads without central isolation facilities or center lines, motor vehicles should use dipped headlight 150 away from the opposite direction when meeting at night, and dipped headlight should be used when meeting with non-motor vehicles on narrow roads and bridges. However, there are still many drivers who abuse the high beam, because some drivers are not strong in safety awareness and only care about their own sight and ignore the feelings of others. Obviously, some car manufacturers also realize that they cannot change the style of these people, so solve the problem technically. Mercedes-Benz recently announced that it will equip the 2015 CLS model with a new multi-beam LED headlight (MULTIBEAMLED). The technology uses a plurality of LED light emitting units, so that the high beam of the car can realize high-precision lighting, thus avoiding interference with the driver of the car. From the description of Mercedes-Benz, even if you are driving a high beam and the other party, you don't have to worry about the safety problems caused by it. Specifically, the MULTIBEAMLED headlights developed by Mercedes-Benz are equipped with a number of special LED modules, each consisting of 24 independently controlled LED light emitting units. The beam of the high beam comes from these LED light emitting units. The key point is that these LED light emitting units can be automatically opened and closed according to road conditions, thus controlling the irradiation area, brightness, etc. of the high beam lamp. Generally speaking, if you come across the car, the MULTIBEAMLED headlights will reduce the brightness of certain areas, thus avoiding the dizziness of the driver. How to judge the road condition and realize automatic adjustment of high beam? The secret lies in the camera behind the windshield. The camera is responsible for monitoring road information and feeding back the information to four control units, which adjust the headlights to a suitable lighting state at a frequency of 100 times per second. The magic of MULTIBEAMLED headlights goes beyond this. Each headlight also includes a module built for dipped headlight mode and consists of 4 LED light emitting units. If the camera detects a curve in front, the MULTIBEAMLED headlights will automatically adjust the light to the direction of the curve, and the large deflection angle can reach 12 degrees, which is convenient for the driver to understand the road conditions ahead more clearly. It is worth mentioning that Audi's Matrix LED headlights (MatrixLED) Similar to the principle of Mercedes-Benz MULTIBEAMLED headlights. The actual effect of the multibeam headlights has yet to be verified by the market. At least, it is certain that in the future, when facing those high beam enthusiasts, there is no need to be so helpless.
