SamsungPixCell400x275Samsung Electronics has announced PixCell LED, a new automotive LED module optimized for intelligent headlights, including adaptive driving beam (ADB) systems. While aimed at automobiles with human drivers, the company said this will also be aimed at electric and autonomous vehicles. Headlights powered by the LEDs can help improve driver visibility and safety to enhance the driving experience at night and in poor weather conditions such as fog or heavy rain.

“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,” said Un Soo Kim, senior vice president of the LED business team at Samsung. “Beginning with PixCell LED, we will introduce tailored lighting solutions well-suited for future automobiles, including electric and autonomous vehicles.

ADB is designed to help secure maximum driving visibility, Samsung said. In order to prevent glare to other drivers, the ADB system automatically adjusts headlight beam patterns when it detects any object near a moving vehicle, thereby preventing any unnecessary glare. THe company said recent developments in autonomous and connected driving have raised the bar for vehicle safety standards, ultimately boosting demand for ADB systems.

The PixCell LED can monolithically integrate more than 100 ultra-small segments into a single LED chip, while also making the light-emitting area significantly smaller. Segments are separated by a silicon wall to prevent optical cross-talk, offering superior contrast for much greater driver visibility. Samsung said each segment functions like a pixel to meticulously control light distribution, as it distinguishes on and off areas so beam from the headlight only illuminates the exact location where it is needed. The LED offers a 300:1 contrast ratio and a maximum wattage of 50W.

In addition, the LED can reduce the headlamp size by 30% to 50%, thanks to a smaller light-emitting area, shrunk to 1/16 the size (15.44 mm by 2.7 mm) of conventional discrete LED modules. Samsung said this allows greater freedom in designing sleeker and more elegant lamps.

Samsung said it is shipping its PixCell LEDs to lamp manufacturers for use in next-generation electric cars, and has provided enough of the LEDs to light more than 300,000 electric vehicles.
