Wholesale Solar led light Factory
The mature LED silicon substrate technology also makes ;AFS have more stable temperature characteristics. Unless there is a wide-angle DMD device specially customized for headlights in the future. The first \;AFS that has been launched, Osram’s EVIYOS, can achieve 1024 pixels on a Wholesale Solar led light Factory single chip of 4mm;4mm, and a single pixel achieves a luminous flux of 3lm. The advantage of LED+DMD is that the technology is relatively mature, and the main parameters such as brightness and efficiency are also good enough.
ADB (Adaptive Driving Beam) market share trend assessment No matter what kind of intelligent lighting action is implemented, the core of its light source technology is to divide the far and near light types into multiple areas with varying numbers, and based on the data of the camera or sensor Input and preset algorithms carry out switch control or brightness adjustment for each area.
And \;AFS integrates a matrix-type CMOS control circuit in the silicon substrate of the chip in advance, and combines it with the chip that is also processed by the matrix-type microstructure to realize the separate opening and closing of each independent microstructure area on the chip. The main limitation is that the optical efficiency is relatively low due to the loss of the polarizer and the liquid crystal panel, and the improvement space is effective in principle.01 Introduction:
The development trend of smart headlights The concept of headlights that change the light type according to different road conditions was first proposed in 1958, but it was technically difficult to achieve in the era when halogen lamps were the main light source of headlights. The currently available \;AFS pixels are in the order of 1,000, and are expected to be upgraded to 10,000 in the next few years. Figure 3 Example of LCD-style smart headlights (picture source: HELLA official website) (3) DLP-style and LCD-style smart headlights are developed for similar reasons, as the current mainstream technology of projection equipment based on DMD devices (Digital Micromirror Device, Digital Micromirror Device) )
