NIO ES9 is equipped with ams and Osram’s new generation ambient lighting solution

Today, Osram (SIX: AMS) announced that its OSIRE™ E3731i smart RGB LED based on the OSP Open System Protocol has been successfully introduced into NIO's new smart pure electric executive flagship SUV - NIO ES9. This is also the first time that ams OSIRE™ E3731i has been used in a NIO brand vehicle to create an immersive and highly personalized cockpit dynamic light and shadow experience.

Car interior lighting is gradually developing from a simple ambience embellishment to smart and interactive, and consumers' demand for immersive cockpit experience continues to increase. As a pioneer and leading brand in the global smart electric vehicle market, NIO has always focused on user experience and continues to explore more possibilities for cockpit interaction in its flagship models.

On April 9, 2026, NIO ES9 was officially released and launched pre-sale, offering three models: Executive Deluxe Edition, Executive Signature Edition and Horizon Special Edition. It is officially positioned as "the culmination of NIO's eleven years of system innovation" and "the pioneer of the smart pure electric executive flagship SUV category." Li Bin, founder, chairman and CEO of NIO, said that ES9 will lead the executive flagship SUV into a new era of pure electric power.

NIO ES9 is equipped with OSIRE™ E3731i smart RGB LED, creating a high-end cabin atmosphere with both a sense of technology and warmth.

In terms of interior experience, NIO ES9 deeply integrates luxurious texture and immersive atmosphere. The entire car adopts a six-layer surround ambient lighting design, with a total light strip length of 10,404 mm. Such a sophisticated design also puts forward higher requirements for the dynamic effects, color consistency and system integration complexity of the ambient lighting. The traditional LIN bus architecture is difficult to support large-scale dynamic light effect applications due to limitations in bandwidth and number of nodes. To this end, NIO chose to cooperate with ams and Osram to introduce OSIRE™ E3731i smart RGB LED based on the OSP open system protocol to create a high-end cockpit atmosphere with both a sense of technology and warmth.

OSIRE™ E3731i integrates R/G/B LED and embedded driver IC into a single component. Each chip has built-in factory-calibrated color, brightness data and temperature sensors. The external microcontroller can independently address and control each LED in a daisy-chain topology through the OSP protocol, and read back the temperature value in real time to optimize the color algorithm. The product has passed AEC-Q102-003 automotive certification and meets the patent compliance requirements of each vehicle-producing country. On NIO ES9, OSIRE™ E3731i brings three clearly noticeable functional upgrades to users:

The color of the entire car is accurate and consistent: nearly a hundred LEDs are distributed in the dashboard surround area and door trim panels. The factory calibration data built into each chip eliminates the need to calibrate each chip one by one after the vehicle comes off the production line, ensuring highly consistent color performance in each area and significantly improving mass production consistency.

Lights move with the music: When music is played, the color and brightness of the ambient lights can change with the melody and rhythm, creating an immersive experience of "music visualization". The high bandwidth of the OSP protocol allows the main controller to update the status of more than 200 LEDs within 10 milliseconds, ensuring that dynamic lighting effects are low-latency and smooth without lag.

Driving situation linkage and personalized settings: The ambient light can automatically adjust according to the cockpit situation, showing dynamic effects such as flowing water and breathing. Users can also set different atmosphere themes according to personal preferences, and all settings support OTA continuous upgrades.

ams-OSRAM OSP open system protocol is the key to achieving the above functions. This protocol is a connection solution developed for high-density lighting systems. It adopts CAN-FD physical layer design and can connect up to 1,000 LEDs in series with only two differential buses, greatly simplifying the number of wiring harnesses and controllers. More importantly, OSP is free and open to all automobile, LED, lighting system and microcontroller manufacturers, and has officially entered the ISO international standardization process (project number: ISO 26341-1). This open architecture provides NIO with higher supply chain flexibility and technical autonomy, so that everything from hardware selection to software-defined lighting is not restricted by proprietary protocols, further realizing an immersive experience of upper and lower lights and sound and light integration in the ES9 cockpit.

The cooperation between NIO and ams-OSRAM has gradually extended from external lighting to the field of interior smart lighting. Previously, ams and OSRAM’s smart multi-pixel LED product EVIYOS™ HD 25 has been introduced into many NIO models; the successful installation of OSIRE™ E3731i this time further deepens the collaborative innovation between the two parties in the field of smart automotive lighting. In the future, ams and Osram will continue to promote the popularization of OSP open protocols and smart RGB LED technology, work with Chinese new energy vehicle manufacturers to explore more innovative possibilities of light and shadow interaction in smart cockpits, and jointly create a new smart lighting ecosystem.
