Digital LED Solution for Automotive

Next-Generation Viable In-Car Lighting

The next generation of in-car ambient lighting will typically comprise of 10 to 30 LEDs mounted on a flexible light strip. Each 'group' consists of one red, green and blue LED to form a 'pixel', which is then intelligently controlled by the ISELED smart RGB LED driver, effectively replacing the present cumbersome and costly work-around utilizing multiple microcontrollers and a slow LIN bus.

Until now, ISELED smart LED drivers have only been available for purchase integrated in an LED module. The INLC10AQ (previously denoted as INLC100Q16) is the first standalone driver available that enables manufacturers to custom design their own choice of external LED strips.

Several LED-related solutions for the automotive market are continuously being developed under the umbrella of the open ISELED Alliance. There are currently 28 partners in the ISELED Alliance.

The Alliance Members include:  Allegro Microsystems, AlpsAlpine, Brightek, Cemm Thome, CoAsia, DesignLED, Display Lab Pforzheim Uni, Dominant Opto, Dräxlmaier, Dr. Schneider, Elmos, Everlight, Feno, Grammer, Grupo Antolin, Harvatek, Hella, Inova Semi, iSYS RTS, Lightworks, Lucie Labs, Magna, Melexis, Microchip, Novem, NXP, Osram Continental, Osram, Prettl Group, TE Connectivity, Techniplas, UG Systems, Valeo, Xingyu Automotive and Yanfeng.
