Abstract
A method is provided for controlling a power converter () to provide a uniform dimming range to a solid state lighting load () independent of a type of dimmer. The method includes detecting maximum and minimum phase angles of a dimmer () connected to the power converter () during operation of the solid state lighting load (), 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.
