Commissioning coded light sources
First Claim
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.

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.

13. A method for commissioning a light source in a coded lighting system, comprising the steps of:
-
emitting coded light from a plurality of light sources; detecting light by a remote controller; determining, by the remote controller, an identifier of the light source based on the detected light, thereby identifying the light source by selectively increasing the sensitivity of a light detector on the remote controller;
successively identifying each of the plurality of light sources arranging in a memory of the remote controller each of the plurality of identified light sources; andtransmitting, by the remote controller, a command to the identified light source to at least partly switch off its light emission, wherein the command is transmitted in response to identifying the light source, thereby commissioning the light source.

14. A light source commissioning remote control, comprising:
-
a light detector coupled to a processor, the processor configured to determine an identifier of a plurality of light sources based on light detected by the light detector; a transmitter operable to transmit a command to an identified one of the plurality of light sources to at least partly switch off its light emission; the light detector operable by the processor to vary the sensitivity of the light detector.
