The invention provides a method and device for modulating the light emission of a lighting device by keying each pulse (14) of a sequence of pulses (16) contained in the control signal (10) according to a spreading code. Thus, the light emission of a lighting device may be identified by detecting the spreading code used for modulating the light emission. The invention is particularly suitable for lighting means containing several lighting devices such as a LED lighting board with dozens of LEDs since the light emission of each lighting device may be detected by the spreading code used for modulating the light emission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for modulating the light emission of a lighting device","description":"The invention relates to controlling a lighting device, particularly to the modulation of light generated by a solid state lighting (SSL) device.
