Open System Protocol
The Open System Protocol (OSP) (https://ams-osram.com/technology/open...) is a simple, open network technology for connecting LEDs, sensors, actuators and other devices in a car. Developed by ams OSRAM, the OSP is available for use completely free, with no license or royalties, by any manufacturer of LEDs or other devices. It’s particularly suitable for connecting hundreds of low- or mid-power LEDs in a dynamic lighting system, an increasingly popular option for automotive interior ambient and exterior lighting.
