Abstract
In one embodiment, an electronic lighting system comprises a first light source (L1) adapted to emit light with a first brightness as a function of a first driving signal (PWM1) having a first frequency (f1), at least one second light source (L2) having a main light sensor (Als2) for providing an brightness of light surrounding the second light source (L2), wherein the first light source (L1) is arranged in visual connection with the at least one second light source (L2). Thereby, the second light source (L2) is prepared to emit light with a second brightness as a function of a second driving signal (PWM2) with a second frequency (f2), the second frequency (f2) of the second driving signal (PWM2) being adjusted to a light frequency (fL) of the light emitted by the first light source (L1), the light frequency (fL) being detected by means of the main light sensor (Als2). Furthermore, a method for lighting synchronization is described.
