Driving in bad weather or driving at night comes with obvious risks, and anything that can improve visibility is a step towards better road safety. Samsung Electronics’ PixCell LED does precisely that, with added benefits.
Intelligent headlights or adaptive driving beam (ADB) systems that can improve driving visibility are becoming more important than ever, especially with connected driving and driverless technology on the rise. This driver assistance technology is able to detect objects in proximity to a moving vehicle and make an automatic adjustment of the beam pattern, in order to prevent glaring.
The PixCell LED that Samsung just unveiled does three important things that take ADB systems to the next level.
The LED chip integrates over 100 small segments, each of them able to control light distribution, which leads to headlights having a greater precision in selectively illuminating targeted areas. A silicone wall is used to separate the LED segments, to prevent optical signals interfering with one another and create a stronger contrast, with a 300:1 ratio.
Ultimately, this helps drivers have better visibility in potentially dangerous, poor-light conditions, such as heavy rain or fog.
Another advantage of the PixCell LED is that it can help improve headlight design, because the light-emitting surface is only 15.4mm x 2.7mm, which is the equivalent of only 1.16 of conventional LED modules used in ADB systems. And with headlamps that can be even half the size of standard ones, overall car design is also improved.
Last but not least, the PixCell LED is based on automotive lighting technology, which makes it versatile enough to be customized and used for different types of lamps. And, it also complies with various international regulations for lamp design.
Samsung announced that it has already begun shipping the PixCell LED to lamp manufacturers and that over 300.000 electric vehicles are set to use this new lighting technology.
