(57) Abstract :
Coded light has been proposed to enable advanced control of light sources and transmit information using light sources. Methods
devices and systems configured to operate a coded lighting control system which is robust to interference from other sources of
light are proposed. The method is based on sensing the light by a remote control device and based on the sensing result adapting
the identifiers used by the different light sources. By assigning a code identifier to the light source based on light received by the
light receiver the code identifiers may be selected such that the influence of light interfering with the light source identifiers may
be mitigated.
