    • 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.
    • 提供了一种方法和相应的照明装置(100),以及接收机,其采用在可调光照明系统中提供码调制的兼容性的码调制。 照明装置包括用于调光输出光(102)的装置,其采用多个调光模式,每个调光模式通过相应的调光方法表示对照明装置的光输出进行调光,以及用于在光输出(103)中嵌入代码的装置, 。 用于在光输出中嵌入代码的装置使用码调制,其基于控制从照明装置输出的瞬时暗光,使得在时间段T期间输出的调光光的积分值被调制以嵌入代码。 然后可以随后在接收机处通过集成和转储处理从调制的光中提取代码,而不了解照明装置的调光方法和/或调光级别。
