RGB device transforms dynamic in-vehicle lighting
An RGB LED module, the ams Osram Osire E3731i enables the creation of dynamic color and motion effects across hundreds of LEDs for automotive interior lighting. Using the company’s license-free Open System Protocol (OSP), the device’s digital core can communicate with any microcontroller over a standard serial bus interface.
The module’s trio of LEDs are co-packaged with an embedded IC that provides drivers for each LED, a serial bus interface, temperature sensor, and on-chip memory. OSP allows an external microcontroller to transmit instructions to modulate color and brightness individually to each LED. Up to 1000 LEDs can be connected in a daisy chain and controlled by a single microcontroller.
The Osire E3731i is characterized at the factory, and its optical performance data is stored in on-chip memory. This makes it easier for automotive manufacturers to perform end-of-line calibration of interior lighting systems, while ensuring optical uniformity and consistency across LED arrays.
The OSIRE E3731i comes in a surface-mount package and is AEC-Q102-003 qualified. Register for the Open System Protocol 1.0 by using the link to the product page below.
