Microcontroller-optimized Pulse-width Modulation (PWM) Drive of a Light-emitting Diode (LED) |
摘要 |
A method for operating a controlled illumination apparatus, the illumination apparatus comprising at least one pulse-width modulation (PWM)-controlled LED, the method comprising carrying out a duty cycle sweep of the PWM signal driving the LED while sensing at least one parameter indicative of the power consumption of the LED to compute a curve reflecting the duty-cycle dependency of the power efficiency of the LED.
