Claim Text:
1. A dimmer for solid-state lighting (SSL) fixtures, comprising: a dimming circuit configured to provide an AC output voltage to the SSL fixtures; a controller coupled to the dimming circuit and configured to derive a phase angle for the AC output voltage, the phase angle corresponding to a phase cut in the AC output voltage; a dimming input connected to the controller and configured to receive a dimming control signal representing a dimming level for the SSL fixtures, the dimming control signal being used by the controller to derive the phase angle for the AC output voltage; and a skip-phase dimming module operable in conjunction with the controller to determine whether the phase angle is an anomalous phase angle that causes a visual anomaly in the SSL fixtures, and to skip the phase angle if the phase angle is determined to be an anomalous phase angle.
