Matrix LED

LED light beads have the characteristics of small size and fast response, using multiple LEDs to arrange and control them according to the matrix, with the help of multiple individually addressable (Individual Addressable) is the simplest solution to realize multi-pixel intelligent headlights. Compared with ordinary LED headlights, matrix LED headlights because of the use of multiple LED lamp beads, need to drive more roads, and need to give each or several LED lamp beads light distribution to make it become an independent pixel unit. At present, a number of OEMs have already used Matrix LED headlights, and the related technology has been more mature, with lower development uncertainty and relatively shorter cycle. However, due to the limitation of LED bead size, there is limited space for pixel upgrade in the future.

Matrix LED car lights show

Representative company: HELLA, in 2017, the company demonstrated the “matrix HD84 headlight module” contains a total of 84 LEDs, each of which is controlled by a separate chip behind the scenes, and can achieve 0-100% light intensity. The module can make different light distribution schemes according to different traffic conditions, weather conditions and road conditions, once another vehicle enters the light distribution area of the headlights, HELLA's set of lights can choose to dynamically conceal the other vehicle's area to prevent glare phenomenon, when the user drives into a traffic sign or slippery road, the light set will also automatically reduce the brightness of the LED, to avoid blurred vision of the user or the driver on the other side. or the opposite driver blurred vision. Currently, HELLA's set of light clusters have been equipped on the new generation of Mercedes-Benz E-Class.
