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 pre-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, Grupo Antolin, Brightek, Changzhou Xingyu Light Co., DesignLED, Display Lab Pforzheim University, DOMINANT Opto, Dräxlmaier, Dr. Schneider, Everlight, Feno, Hella, Inova Semiconductors, iSYS RTS, ITSWELL, Lightworks, Lucie Labs, Magna, Melexis, Microchip, Novem, NXP, Osram Opto Semiconductors, Prettl Group, TE Connectivity, Techniplas, UG Systems, and Valeo.

EMI EMS Investigation Report


  • Integration of LEDs, LED controller and advanced communication link in one small 3 mm package
    - system cost reduction
  • Calibration of LED and driver during production process of LED module
    - no binning classes, no bar coding – calibration data stored in LED
    - no look up tables in µC anymore
    - system assembly using LED from the tape with guaranteed parameters


  • Bi-directional communication between µC and LED module with lowest latencies
    - EMI robust design based on 2 Mbps communication - no dedicated clock
    - LED temperature can be diagnosed individually by µC
    - efficient use of bandwidth due to individual addressing of each LED
