Abstract
Commissioning a coded light source in a lighting system is accomplished by using a remote controller. When an identification of a light source is successful, a control message is sent to that light source to at least partly switch off its light emission. Thus the light contribution of the identified light source is suppressed. Thereby the chance of coded light from an already identified light source colliding with identifiers comprised in coded light emitted by other light sources is reduced. When no more coded light is detectable, a sensitivity of the remote controller can be increased until coded light again is detectable. Further light sources can then be identified and commissioned.
