The new lights also allow the headlights to be 30-50% smaller
Samsung has introduced a new smart headlight system called PixCell LED which will improve road safety. It allows selective lighting control to improve driving visibility and help drivers react better to the environment. It is basically an Adaptive High Beam (ABD) system.
“Much more than just an automotive light source, Samsung’s PixCell LED is based on new lighting technology designed to improve road safety and driving comfort,” said Un Soo Kim, senior vice president of the LED sales team at Samsung Electronics. “Starting with PixCell LED, we will introduce bespoke lighting solutions well suited for future automobiles, including electric and autonomous vehicles,” he added.
ABD is assistive technology that has been designed to help ensure maximum driving visibility. It helps prevent glare for other drivers and also automatically adjusts the headlight beam patterns when it detects an object near a moving vehicle, preventing unnecessary glare.
This technology was developed in conjunction with Samsung’s semiconductor unit, known for manufacturing silicon for many brands of smartphones and PCs. The new PixCell LED can monolithically integrate over 100 ultra-small segments into a single LED chip while dramatically reducing the light emitting area.
Interestingly, the LED segments are spectated by a silicon wall to prevent optical crosstalk, which is similar to the ISOCell camera image sensors that Samsung uses on its smartphone cameras. The light emitting area is reduced by 1/16 of a standard moldable LED and this nebulizes the PixCell LED to reduce the size of the headlight by almost half. This in turn will allow for cooler designs and sleeker headlights.
The light distribution and brightness levels of the PixCell LED are designed using automotive lighting software, making them easily adjustable to meet various automotive lamp regulations and requirements around the world. . Based on a single standard headlight design, lamp manufacturers can customize light output to meet different design needs and benefit from reduced lead times for development, production, supply and time to market. Samsung said in the press release.
Samsung says it has started shipping PixCell LEDs to lamp manufacturers for use in next-generation electric cars and has already supplied enough PixCell LEDs for more than 300,000 electric vehicles.
