Samsung Electronics, advanced digital component solutions, unveils PixCell LED, a new automotive LED module optimized for intelligent headlights, such as adaptive driving beam (ADB) systems. ADB headlamps powered by Samsung’s PixCell LEDs help improve driver visibility and safety to enhance the overall driving experience at night and in poor weather conditions such as fog or heavy rain.
Un Soo Kim, Senior Vice President of the LED Business Team, Samsung Electronics, said: “Much more than a simple automotive lighting source, Samsung’s PixCell LED is based on new lighting technology designed to improve road safety, and driving convenience. Beginning with PixCell LED, we will introduce tailored lighting solutions well-suited for future automobiles, including electric and autonomous vehicles.”
ADB is an advanced driver assistance technology designed to help secure maximum driving visibility. To prevent glare to other drivers, ADB automatically adjusts headlight beam patterns on detecting an object near a moving vehicle, thereby preventing any unnecessary glare. Recent developments in future automotive technologies, such as autonomous and connected driving, have been raising the bar for vehicle safety standards and ultimately boosting demand for ADB systems.
The new PixCell LED can monolithically integrate more than 100 ultra-small segments into a single LED chip, making the light-emitting area significantly smaller. These LED segments are separated by a silicon wall to prevent optical cross-talk for much greater driver visibility. Each segment functions as a pixel to meticulously control light distribution so that the beam from the headlight only illuminates the exact location where it is needed.
With the light-emitting area shrunk to 1/16 of conventional discrete LED modules for ADB systems, the PixCell LED can reduce the headlamp size by 30-50%, allowing greater freedom in designing sleeker and more elegant lamps.
PixCell LED, designed using automotive lighting software, makes them easily adjustable to meet diverse regulations and requirements for automotive lamps. Based on a single standard headlamp design, lamp makers can customize the light output to suit varying design needs and enjoy reduced lead time for development, production, supply and time-to-market.
