    摘要： A method of controlling a light driver includes determining, by a secondary controller of the light driver, an actual voltage drop across a regulator of the light driver; determining, by the secondary controller, a target voltage drop of the regulator; calculating, by the secondary controller, a theoretical input voltage of the regulator based on the target voltage drop and an output voltage of the regulator; determining, by the secondary controller, whether the theoretical input voltage is within a first range; and in response to determining that the theoretical input voltage is within the first range, generating, by the secondary controller, a first feedback signal for transmission to a primary controller of the light driver based on the target voltage drop and the actual voltage drop.

    摘要： A light driver includes a pulse generator circuit configured to generate a pulsed signal based on a rectified input line voltage, a dimming detection circuit configured to determine whether phase-cut dimming is present at an input of the light driver based on the pulsed signal and to generate a phase-cut detection signal, and an input selection circuit configured to apply a first voltage or a second voltage to a reference input of a power factor correction (PFC) circuit of the light driver based on the phase-cut detection signal.

    摘要： A method of driving a light source by a light driver includes measuring a current output signal of the light driver, calculating a percent change in output signal, determining whether the percent change in output signal is greater than or equal to a first threshold, and in response to determining that the percent change in the output signal is greater than or equal to the first threshold, calculating a percent change in reference voltage based on a current reference voltage and a previous reference voltage, determining whether the percent change in reference voltage is less than a second threshold, and in response to determining that the percent change in reference voltage is less than the second threshold, deactivating filtering and averaging of a dimmer signal received from a dimmer for a period of time, and reactivating the filtering and the averaging of the dimmer signal.

    摘要： An active gain control circuit includes a dynamic voltage divider having a variable resistance configured to attenuate a rectified input line voltage to produce a reference signal, a filter-divider circuit configured to extract a DC-level attenuated reference voltage from the reference signal, and an operational amplifier configured to receive the DC-level attenuated reference voltage and a regulation voltage, and to generate a gate control signal based on a difference between the regulation voltage and the DC-level attenuated reference voltage, the variable resistance of the dynamic voltage divider being controlled by the gate control signal, and a comparison voltage generator configured to attenuate a comparison voltage to generate the regulation voltage.
