Automotive interior lighting association tops 50 members
The new companies are: Blue Whale (MCUs), Lextar (automotive lighting), Liteon (LEDs), Technica (communication test and validation), Asteelflash (electronic manufacturing) and YTMicro (MCUs) – bringing the total in the alliance to 52 companies.
The system includes a 2Mbit/s serial bus that can link strings of up to 4,096 individually-addressable LEDs.
Every LED in a 100 device chain can be updated in 5.25ms, allowing frame rates of over 100Hz.
Factory calibration can be used to put emission of an RGB LED within a 1 step Mac Adam ellipse. Per-LED temperature sensing allows automatic local drift compensation. “There are no binning classes, bar coding and look up tables for calibration on the microcontroller anymore,” according to ISELED.
An extension of the original ISELED protocol, called ILaS, adds other components such as matrix LED lights, sensors and actuators via two-wire connection.
Typical applications are: dynamic ambient lighting, roof lighting, functional lighting and display back-lighting.
