摘要： Systems and methods to change a light output level using adaptive frequency control are provided. A switched mode power converter is configured to switch output current to a light emitting diode (LED) module, which includes an LED lighting element, at a switching frequency. Control circuitry is configured to receive a dimming control input that corresponding to a desired light output level of the LED module. The control circuitry is also configured to provide a pulse width modulation (PWM) output configured to pulse width modulate the output current, the PWM output having a pulse width, a PWM frequency, and a PWM period corresponding to the PWM frequency. The control circuitry is also configured to adjust at least one of the PWM period and the switching period in response to a change in the dimming control input, such that a light output level of the LED module is appropriately changed.
