Abstract:
1. A remote controller for commissioning a light source in a coded lighting system comprising a plurality of light sources capable of emitting coded light, comprising: a light detector; a processing unit coupled to the light detector and arranged to determine an identifier of the light source based on light detected by the light detector, thereby identifying the light source; a transmitter arranged to transmit a command to the identified light source to at least partly switch off its light emission; wherein the processing unit is configured to instruct the transmitter to transmit the command in response to identifying the light source, thereby commissioning the light source; a variable gain amplifier coupled to the light detector and arranged to increase a sensitivity of the light detector until at least one identifier is detectable in the received light; a memory coupled to the processing unit and configured to store identifiers of the plurality of light sources; the processing unit configured during determination of the identifier of the light source to compare the identifier of the light source with the stored identifiers of previously identified light sources; and the memory and processing unit operable to add the identifier of the identified light source to the memory in response to the identified light source having been identified.
