摘要

Disclosed is a communication system (100) comprising an illumination system (110) with a plurality of dimmable light sources (111, 112, 113, 114). The system further comprises a controller (130) for controlling the light sources such that they emit coded light and a receiver (200) with a light detector (211) and a CPU (230). The light detector has an output coupled to the CPU and is capable of receiving light from a least one of the light sources. The CPU is arranged to decode the signal received from the light detector and is arranged on the basis of the outcome of the decoding, to decide on an action to be taken.
