摘要： A system and method control an amount of power delivered by a power converter (220) to a solid state lighting load (240). It is determined whether a dimmer (204) is present between a voltage source (201) and the power converter (220) based on a rectified input voltage from the voltage source. When the dimmer is determined to be present, an operating point of the power converter is adjusted to increase the amount of power delivered by the power converter to the solid state lighting load by a compensation amount, so that the increased amount of power is equal to an amount of power delivered by the power converter when the dimmer is not present.

The method includes detecting first and second values of a phase angle of a dimmer connected to a power converter driving the solid state lighting load, the first and second values corresponding to consecutive half cycles of an input mains voltage signal, and determining a difference between the first and second values. When the difference is greater than a difference threshold, indicating asymmetric waveforms of the input mains voltage signal, a selected corrective action is implemented.

摘要： A method is provided for controlling a power converter (220) to provide a uniform dimming range to a solid state lighting load (240) independent of a type of dimmer. The method includes detecting maximum and minimum phase angles of a dimmer (204) connected to the power converter (220) during operation of the solid state lighting load (240), and dynamically adjusting an output power of the power converter based on the detected maximum and minimum phase angles of the dimmer. The adjusted output power of the power converter adjusts a high end level of light output by the solid state lighting load at the maximum phase angle to match a predetermined high end value and adjusts a low end level of light output by the solid state lighting load at the minimum phase angle to match a predetermined low end value.

摘要： Disclosed are devices and related methods for optimally extending the range of light output of solid‐state light sources, particularly at minimum light levels, through a power converter that includes a phase detector, a processing unit and a switch.

The processing unit is configured to initiate a predetermined shutdown period in response to each detected rising edge. The switch is configured to provide a control signal that deactivates the power converter during the shutdown period, preventing the power converter from providing power to the solid state light unit during the shutdown period.
