DOMINANT Opto Technologies Will Use OSRAM’s OSP in Their Next Intelligent RGB LED Generations

OSP RGB LED automotive ambient lighting

Dynamic ambient lighting, controlled intelligently with animation effects, color changes, and intensity variations, serves various purposes – such as setting moods, conveying information, displaying warnings, and effectively presenting the car’s branding. These functionalities demand intelligent RGB LEDs and a communication protocol compatible with any microcontroller’s standard serial interface, capable of carrying high-frequency control signals.

The Open System Protocol (OSP) infrastructure, introduced alongside ams OSRAM’s OSP-compliant intelligent RGB LED, the OSIRE® E3731i, fulfils these requirements. With DOMINANT Opto Technologies also joining the OSP ecosystem, automotive manufacturers can from now on have a second source of OSP-compatible LEDs.

The OSIRE® E3731i, the industry’s first OSP-compliant intelligent RGB LED, features an integrated ASIC (Application-Specific Integrated Circuit) that drives three RGB emitters, ensuring excellent color homogeneity by providing measurement data for automatic color calibration. This calibration is crucial, especially for long strings of LEDs throughout the car interior. The OSIRE® E3731i supports daisy-chain configurations with up to 1000 LEDs in a single string, requiring just two communication and two power lines each, streamlining implementation and potentially enabling single-layer PCB designs.

AEC-Q102-qualified and compliant with automotive EMC requirements.

DOMINANT Opto Technologies is delighted to join the OSP ecosystem. This enables DOMINANT to expand its existing seddLED product portfolio to fulfill various customer requirements. The seddLED+ A3H will be the first OSP-compliant intelligent RGB LED to be launched on the market.
