    Abstract: A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.

    Abstract: A two-way load control system comprises a power device, such as a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the power device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.

    Abstract: A load control system may comprise load control devices for controlling respective electrical loads, and a system controller operable to transmit digital messages including different commands to the load control devices in response to a selection of a preset. The different commands may include a preset command configured to identify preset data in a device database stored at the load control device and/or a multi-output command configured to define the preset data for being stored in the device database. The system controller may decide which of the commands to transmit to the load control devices in response to the selection of the preset.
