The Iseled alliance is developing hardware and software for a new LED lighting concept in vehicles. 2 Mbit/s are available for LED control.

The Italian automotive supplier Olsa and the Belgian semiconductor manufacturer Melexis have joined the Iseled alliance. The now nine alliance members develop and market hardware and software for a new interior lighting technology that goes beyond the possibilities of the LIN bus.

The key product for this is an €»intelligent€« digital RGB LED in a compact 3 mm housing. An integrated controller performs control tasks that would otherwise be outsourced to a microcontroller. This approach significantly simplifies LED control and extends the control options for LED lighting in automobiles.

A total of up to 4079 of these digital LEDs can be arranged via a differential 2-wire bus with a data rate of 2 Mbit/s and controlled by an external controller such as NXP's S32K series. The data rate goes well beyond the 20 kbit/s of the LIN bus and should enable lighting effects at video speed, according to the alliance.

Iseled alliance expects more members

The first Iseled products and a development kit are now available. The goal of the partners is to develop a complete ecosystem of hardware and software. The alliance was founded in 2016 by the German fabless semiconductor manufacturer Inova Semiconductors together with the Malaysian LED manufacturer Dominant Opto Technologies, NXP, the University of Pforzheim und TE Connectivity. Lucie Labs, Valeo, Olsa and Melexis have now joined as additional members.

Talks with other companies are currently underway. Inova Semiconductors Managing Director Robert Kraus said that he would soon be able to welcome the next members. He already did this after the Olsa Group joined the alliance – one day later Melexis announced its membership.
