Abstract: A load control device may include first, second, and third drive circuits for controlling respective ones of the emitter circuits, and may generate first, second, and third drive signals for controlling each of the first, second, and third drive circuits, respectively, to adjust a present color of the cumulative light emitted by the emitter circuits towards a target color. The control circuit may be configured to pulse-width modulate the first, second, and third drive signals on a periodic basis at an operating period, where each period comprises at least three time slots. The control circuit may be configured to determine first, second, and third on times of the first, second, and third drive signals of the first, second, and third pulses, respectively, based on the target color.

Abstract: A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three-wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.
