ams-OSRAM OSIRE E3731i Intelligent RGB LED Integrated Into NIO ES9 e-SUV Cabin Lighting System

ams-OSRAM AG has announced the integration of its OSIRE E3731i intelligent RGB LED into the NIO ES9 e-SUV, marking the first deployment of this lighting technology within the automaker’s vehicle lineup. The solution has been introduced to create a more immersive and personalized cabin atmosphere through advanced ambient lighting functionality. The ES9 incorporates a six-layer wraparound ambient lighting architecture featuring a total light strip length of 10,404 millimeters across the interior cabin.

The OSIRE E3731i combines RGB LEDs, an embedded driver IC, factory-calibrated brightness and color data, along with an integrated temperature sensor into a compact single package. This integration allows every LED unit to be individually controlled in real time, enabling optimized lighting algorithms and improved dynamic performance throughout the cabin environment. The technology is designed to support highly synchronized lighting behavior while maintaining precise color calibration across multiple lighting zones inside the vehicle.

Key Ambient Lighting Features in the NIO ES9

The intelligent lighting platform inside the ES9 delivers several advanced personalization capabilities for passengers and drivers. Nearly 100 LEDs installed across the instrument panel and door panels maintain consistent color performance throughout the cabin. The system also supports music-responsive ambient lighting effects where brightness and color patterns automatically adjust according to melody and rhythm. In addition, the lighting environment can synchronize with driving scenes and cabin atmosphere modes while enabling customized presets supported through OTA software updates.

OSIRE E3731i Technology Specifications

The intelligent RGB LED package has been engineered to simplify system integration while enhancing lighting accuracy and responsiveness. By integrating multiple electronic and sensing components within a single module, the solution supports advanced interior lighting applications for modern connected vehicles. The architecture also improves lighting consistency during varying operating conditions by continuously monitoring thermal performance through the integrated temperature sensor.

NIO ES9 Ambient Lighting System Overview
