ams OSRAM (Korea Representative: Seok-Won Kang), a global leader in intelligent sensors and emitters, has joined hands with Dominant Opto Technologies to implement smart automotive interior lighting.

ams OSRAM today announced a partnership with DOMINANT Opto Technologies, a Malaysian manufacturer of automotive LED solutions, to integrate ams OSRAM’s Open System Protocol (OSP) into DOMINANT Opto Technologies’ next generation of intelligent RGB LEDs for automotive interior lighting.

Through this partnership, both companies seek to drive innovation by encouraging greater collaboration and technological compatibility in the automotive lighting space.

OSP, launched by ams OSRAM in 2023, is an open, license-free communication technology that connects RGB LEDs, sensors and microcontrollers from a wide range of manufacturers. Dominant Opto Technologies’ willingness to integrate OSP into its next-generation products confirms the protocol’s position as a universal way to connect intelligent LEDs in vehicles.

This collaboration between the two companies will support a more flexible supply chain for automakers, allowing them to source interior lighting LEDs and components from multiple manufacturers without having to reconfigure system communications when switching suppliers.

As automotive interior design evolves into the 'third living space', interior lighting has taken on a new meaning. Dynamic interior lighting, which can intelligently control animation effects, color changes, and intensity changes, performs various functions such as setting the mood, conveying information, indicating warnings, and effectively displaying the car brand. These functions require intelligent RGB LEDs and a communication protocol compatible with the standard serial interface of all microcontrollers capable of transmitting high-speed control signals.

The OSP infrastructure, launched together with ams OSRAM’s OSP-compliant intelligent RGB LED, the OSIRE® E3731i, addresses these requirements. With Dominant Opto Technologies joining the OSP ecosystem, automotive manufacturers now have an additional source of OSP-compatible LEDs, driving innovation and flexibility in interior lighting solutions.

The OSIRE® E3731i, an OSP-compatible intelligent RGB LED, features an integrated application-specific integrated circuit (ASIC) that drives three RGB emitters and provides measurement data for automatic color correction to ensure excellent color uniformity.

This compensation is especially important for long strings of LEDs that extend throughout the interior of a car.

The OSIRE® E3731i supports daisy-chain configurations of up to 1000 LEDs in a single string, allowing easy implementation using only two communication and two power lines, as well as potentially enabling single-layer PCB designs.

AEC-Q102 qualified and compliant with automotive EMC requirements, the OSIRE® E3731i sets the benchmark for intelligent RGB LEDs in the automotive sector.

By joining the OSP ecosystem, Dominant Opto Technologies will be able to expand its existing seddLED product portfolio to meet a variety of customer requirements. The seddLED+ A3H will be the first OSP-compliant intelligent RGB LED to be introduced to the market. The company aims to provide prototype samples in Q3 FY2024.
