Take a look at the new smart pixel headlights
Headlights used in modern sedans are brighter and whiter than in the past, but sometimes they are not bright enough and have the potential to temporarily blind drivers in the oncoming lane. Although this headlight can work on deserted dark roads, it is not suitable for heavy traffic in urban and suburban roads. To try to solve this problem, Daimler has developed a new smart pixel headlight system that can more precisely characterize its beam.
The current adaptive high beam system works fairly well, but its effectiveness is limited by installation space. When the sensors detect another car and driver, they dim the individual light-emitting units in the headlight array, or block some of the light-emitting units to create a beam gap. This means that the LED units need to contain the rated power supply components to operate this adaptive beam, and such a small space in the front of the car is constraining the number of LED units, which in turn constrains the overall brightness of the car's headlights.
The developed smart pixel headlight has 1024 built-in pixels, and these controllable pixels are packaged into a "chip". Each pixel has independent hardware to manipulate them, making them more powerful than current standards. Each smart pixel LED can individually dim its output, and their beams can be manipulated more precisely. That is, a very nice dark spot can be created for oncoming cars to mimic a mechanical "corner lighting" system.
The technology is still in its infancy, but developers and their partners are now working hard to get it into mass production.
