Abstract: The lighting device may be configured to perform black body curve fading. For example, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting load is adjusted (e.g., faded) along a black body curve. The control circuit may be configured to determine whether to fade from an initial color to a destination color in a Correlated Color Temperature (CCT) chromaticity space or an XY chromaticity space. The control circuit may be configured to determine whether the initial color and/or the destination color are on the black body curve. When the initial color and the destination color are determined to be on the black body curve, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting device is adjusted from the initial color to the destination color along the black body curve.

Abstract: Systems and methods are disclosed for a load control system which produces a show by adjusting one or more parameter values, such as color temperature, intensity, spectrum, volume, load state, and position of a window covering, as a function of a show time equal to a current time of day. The load control system is responsive to receiving commands to adjust the show time with respect to the current time of day. The load control system is configured to respond to the received commands by initiating a temporary system override in which the one or more parameter values may rewind or forward in time according to the defined show. The temporary override may exit and the defined show may resume at the current time of day after a predetermined amount of time has passed, at a reset time, or in response to a command.

Abstract: A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.
