Open System Protocol (OSP) overview
For dynamic lighting applications and beyond. Is open for everybody (license free) and a full documentation gives full control.
Open System Protocol (OSP)
Open System Protocol (OSP) was developed by ams OSRAM to enable dynamic lighting applications and more.
OSP is open for everybody and free of license. It is based on a master-slave architecture, allowing to control >1,000 devices individually in a chain. OSP is split into a base protocol, covering the lower 3 layers of ISO/OSI, and a device specific application layer.
Enable dynamic lighting applications
The flexibility of OSP allows the implementation of Dynamic Lighting Applications for decoration, warnings, and communication, or even for the integration of interactive functions like in Smart Surfaces by the integration of sensors and actuators.
OSP supports dynamic lighting applications with following key features:
- Address range: 1,024
- Net data: up to 64 bit per message frame
- Data transfer rate: 2.4 MB
- Self-diagnosis, self-addressing, further network layer features
With these data, a master controller can update more than 200 devices with 3 colors (Red/Green/Blue) in 16 bit depth in less than 10 ms.
