摘要:
There is provided a method and corresponding lighting device (100), and a receiver, which employs code modulation which provides a compatibility of code modulation in a dimmable lighting system. The lighting device comprises means for dimming the output light (102), which employs multiple dimming modes, each representing dimming the light output from lighting device by means of a respective dimming method, and means for embedding a code in the light output (103). The means for embedding a code in the light output employs code modulation which is based on controlling the instantaneous dimmed light output from the lighting device such that the integrated value of the dimmed light output during a time period T is modulated to embed the code. The code may then subsequently be extracted from the modulated light by means of an integrate-and-dump process at a receiver, without knowledge of the dimming method and/or dimming level of the lighting device.
