Ams OSRAM has unveiled an intelligent RGB LED, the OSIRE E3731i LED, enabling automotive manufacturers to implement novel dynamic lighting effects in vehicle interiors. This dynamic lighting adds value by combining changes in color and brightness with pulsing, breathing or moving light effects.

Used for both decorative and functional purposes, the OSIRE E3731i LED allows up to 1,000 LEDs to be connected in a daisy chain, controlled via one microcontroller (MCU). The interior lighting is achieved using simpler architecture, fewer components, less wiring and a lower system cost, said the company.
The OSIRE E3731i LED is designed for interior applications that need high dynamic RGB lighting scenarios. The RGB LED is co-packaged with an IC that integrates three LED drivers. It also includes optical measurement data of the three RGB LEDs. The external MCU addresses and controls each device via an open system protocol (OSP), allowing the MCU to run any color algorithm and to optimize the color algorithm.

Other features include a serial bus interface supporting the OSP, a temperature sensor and on-chip memory. Each RGB LED is factory characterized and optical performance data are stored in the LED’s on-chip memory. The on-chip memory facilitates end-of-line calibration of interior lighting systems, very high optical uniformity and consistency when using arrays of hundreds of OSIRE E3731i LEDs, said the company.
The OSIRE E3731i is qualified to the latest AEC-Q102 Annex 3 standard.
