AMS Osram and Dominant Opto Technologies have announced a partnership to integrate AMS Osram’s Open System Protocol (OSP) into Dominant Opto Technologies’ upcoming generation of intelligent RGB LEDs for automotive ambient lighting.
Introduced in 2023, AMS Osram’s OSP is a license-free communication technology that connects RGB LEDs, sensors and microcontrollers from different manufacturers.
Dominant Opto Technologies has decided to adopt OSP in its future products due to the protocol’s “position as a universal method for connecting intelligent LEDs in vehicles”, the company said.
The integration of OSP into Dominant Opto Technologies’ RGB LEDs presents new possibilities for automotive ambient lighting, including mood setting, conveying information, displaying warnings, and presenting the car’s branding.
The OSP infrastructure, alongside ams OSRAM’s OSP-compliant intelligent RGB LED, the OSIRE E3731i, fulfils the requirements for dynamic ambient lighting control, the companies say.
The OSIRE E3731i is the industry’s first OSP-compliant intelligent RGB LED. It features an integrated ASIC that drives three RGB emitters, to provide color homogeneity and to support daisy-chain configurations with up to 1,000 LEDs in a single string.
OSRAM says OSIRE E3731i is AEC-Q102 qualified and compliant with automotive EMC requirements.
Dominant Opto Technologies said it is “delighted to join the OSP ecosystem”, which enables it to expand its seddLED product portfolio with the seddLED+ A3H. The company says this will be the first OSP-compliant intelligent RGB LED on the market, with a prototype sample expected in Q3 of FY2024.
