Frequently Asked Questions


Why ISELED?

Innovative concept of calibrated, digitally addressable, smart RGB LED modules with integrated smart LED driver, connected by a 2 Mbit/s serial daisy-chain bus. Simplifies design and production of products with homogenous, dynamic lighting effects

  • 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
  • includes diagnostic features

What are typical applications of ISELED?

  • Dynamic Ambient lighting
  • Roof lighting
  • Functional lighting
  • Display backlight

Where to order?



What is the calibration accuracy?

  • Allows a 1 step Mac Adam accurate calibration of a defined white point.

How fast can the LEDs in a chain be updated?

  • Updating every single LED in a chain with 100 LEDs is performed in 5.25ms, allowing frame rates of over 100Hz.

What is the max possible length of a LED chain?

  • Up to 4096 LED’s are addressable in a single chain
  • The serial bus supports cable segments between LEDs.
  • The length of cable segments is determined by the cable loss and in a typical automotive application by the EMI requirements. This is a system subject and is dependent on cable type, cable shielding, connectors, etc. 

How long can be the distance from controller I/O to first ISELED?

  • recommended max distance is 15cm

Temperature compensation

  • Temperature compensation can be enabled/disabled with the INIT command for the red channel.
