Samsung Announces new automotive LED module optimized for intelligent headlights
Samsung today announced a new automotive LED module optimized for intelligent headlights, such as adaptive driving beam (ADB) systems. ADB is an advanced driver assistance technology designed to help secure maximum driving visibility. In order to prevent glare to other drivers, ADB automatically adjusts headlight beam patterns when it detects any object near a moving vehicle, thereby preventing any unnecessary glare. ADB headlamps powered by Samsung’s PixCell LEDs will improve driver visibility and safety to enhance the overall driving experience at night and in poor weather conditions such as fog or heavy rain.
Leveraging Samsung’s longstanding expertise in semiconductor technology, the new PixCell LED can monolithically integrate more than 100 ultra-small segments into a single LED chip, while making the light-emitting area significantly smaller. These LED segments are separated by a silicon wall to prevent optical cross-talk, and in turn, offer superior contrast for much greater driver visibility. 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.
The light distribution and brightness levels of the PixCell LED are designed using automotive lighting software, making them easily adjustable to meet diverse regulations and requirements for automotive lamps around the world. Samsung has begun shipping its PixCell LEDs to lamp manufacturers for use in next-generation electric cars and has already provided enough PixCell LEDs to light more than 300,000 electric vehicles.
