    Abstract: A provided wireless wallbox dimmer may accommodate a plurality of button configurations. The dimmer may be configured to contain a variable number of controllably conductive devices. The dimmer may include a yoke that defines a first plane and an antenna that defines a second plane that is substantially parallel to and spaced apart from the first plane. The yoke may have a flange that is oriented angularly offset relative to the first plane and provides a plurality of mounting locations for controllably conductive devices. The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke.

    Abstract: A control device configured for use in a load control system to control an electrical load external to the control device may comprise an actuation member having a front surface defining a capacitive touch surface configured to detect a touch actuation along at least a portion of the front surface. The control device includes a main printed circuit board (PCB) comprising a control circuit, a tactile switch, a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device also includes a capacitive touch PCB that comprises a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB and arranged in a linear array adjacent to the capacitive touch surface.

    Abstract: A load control device may utilize a feedback signal representative of an average magnitude of the load current conducted through an electrical load to control the amount of power delivered to the electrical load. The feedback signal may be generated based on a sense signal that is electrically isolated from the line voltage input of the load control device. Depending on the operational characteristics of the electrical load, the feedback signal may be generated using different techniques. In one example technique, the sense signal may be integrated and filtered to derive the feedback signal. In another example technique, the sense signal may be used in conjunction with an input power of the load control device and an efficiency parameter of the load control device to derive the feedback signal. In yet another example technique, values derived from the foregoing two techniques may be blended together to obtain the feedback signal.

    Abstract: An illumination device and method are provided for controlling light-emitting diodes (LEDs). The LEDs (specifically, the LED loads) are controlled, e.g., brightness and color of the LED loads, independent of a phase-cut dimmer applied to the AC mains feeding a DC power supply. The power supply is active dependent upon the duration of a conduction angle supplied from the dimmer The power supply, however, produces drive currents that are independent from the conduction angle by using a two-stage power supply and a relatively slow and fast control loops that are controlled through a microprocessor-based control circuit. Parameters stored in the control circuit are drawn by the microprocessor to control the two-stage power supply to produce the drive currents independent and decoupled from the conduction angle yet dependent on the controller parameters.

    Abstract: A motor drive unit for driving a motor of a motorized window treatment may comprise software-based and hardware-based implementations of a process for detecting and resolving a stall condition in the motor, where the hardware-based implementation is configured to reduce power delivered to the motor if the software-based implementation has not first reduced the power to the motor. A control circuit may detect a stall condition of the motor, and reduce the power delivered to the motor after a first period of time from first detecting the stall condition. The motor drive unit may comprise a stall prevention circuit configured to reduce the power delivered to the motor after a second period of time (e.g., longer than the first period of time) from determining that a rotational sensing circuit is not generating a sensor signal while the control circuit is generating a drive signal to rotate the motor.

    Abstract: A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and controller devices, such as a remote control device configured to transmit digital messages for controlling the lighting load via the load control device. The remote control device may communicate with the lighting devices via a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages as unicast messages or multicast messages based on the type of user interface event detected. The remote control device, or other master device, may synchronize and/or toggle an on/off state of lighting devices in the load control system.
