摘要：The invention proposes a method for operating a controlled illuminationapparatus, the illumination apparatus comprising at least one PWM controlled LED, themethod comprising the following steps: - carrying out a duty cycle sweep of the PWMsignal driving the at least one LED while sensing at least one parameter indicative of thepower consumption of the at least one LED in order to compute a curve reflecting theduty-cycle dependency of the power efficiency of the at least one LED.
