ams OSRAM and Tongmingliang reach cooperation in automotive ambient lighting business

On April 15, ams OSRAM announced that it has established a partnership with Tongliangliang, a Malaysian automotive LED solution manufacturer, to integrate ams OSRAM’s Open System Protocol (OSP) into Tongliangliang’s upcoming automotive ambient lighting smart RGB LED. ams OSRAM hopes that through this cooperation, it can invite more colleagues in the automotive industry to promote innovation in automotive lighting technology by promoting technological compatibility.

It is reported that OSP, introduced by ams OSRAM in 2023, is an open, license-free communication technology used to connect components such as RGB LEDs, sensors and microcontrollers from different manufacturers.

In this cooperation, Tongming Mingliang promises to integrate the OSP protocol into its upcoming automotive ambient light LED devices. This important collaboration helps automakers build more resilient supply chains, allowing them to source LEDs and components from different suppliers without reconfiguring system communications when changing suppliers.

ams OSRAM said that dynamic car atmosphere lights create atmosphere for vehicles, convey information, display warnings and effectively display car brands by intelligently controlling animation effects, color changes and intensity changes. These functions require the application of smart RGB LEDs and a communication protocol compatible with various microcontroller standard serial interfaces to carry the transmission of high-frequency control signals.

Previously, ams OSRAM has launched the OSP protocol-compatible smart car interior RGB LED device - OSIRE E3731i. Through the OSP protocol, the microcontroller can send instructions to each OSIRE E3731i and obtain the status to achieve high-precision color calibration and temperature compensation.

According to data, OSIRE E3731i is the industry's first smart RGB LED device that complies with OSP standards. The product has an integrated ASIC, can display dynamic light effects, and can connect and communicate with any microcontroller with an SPI interface; the product complies with the AEC-Q102 standard required by automotive EMC.

With Tongmingliang joining the OSP ecosystem, car manufacturers can now have a second RGB LED device product that is compatible with the OSP protocol, further promoting the innovation and flexibility of automotive ambient lighting solutions.

Tongliang Mingliang said that it is pleased to join the OSP ecosystem. This cooperation allows the company to expand its existing seddLED product portfolio to meet various customer requirements. seddLED+ A3H will be the first smart RGB LED device compatible with the OSP protocol, and the company plans to provide prototype samples in the third quarter of fiscal 2024.

ams OSRAM stated that both the company and Tongming Bright have demonstrated the importance of the OSP protocol in the future smart RGB LED architecture. The OSP protocol facilitates simple and cost-effective communication within the LED product chain, allowing automakers to source LED products from different suppliers without redesigning the architecture.

OSP is an open, license-free protocol. ams OSRAM hopes that more partners will join the OSP protocol in the future and contribute to the innovation and compatibility of the automotive lighting community. (Compiled by LEDinside Irving)
