  • Lighting system and a method for controlling a lighting system
    Patent number: 8111021
    Abstract: A method of controlling a lighting system includes a learning procedure. The lighting system includes lighting modules and a controlling device. The lighting modules are arbitrarily arranged, and each lighting module can communicate with neighboring lighting modules via communication units arranged at sides of the lighting module. The learning procedure defines a lighting module arrangement and a communication network for communication between the controlling device and the lighting modules. During the learning procedure, a token is forwarded from one lighting module to another lighting module, while ensuring that all lighting modules are visited by the token. Further, geometric information about how the lighting modules are arranged in relation to each other is generated.
