Abstract: A two-wire load control device (such as, a dimmer switch) is operable to control the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) and has substantially no minimum load requirement. The load control device includes a bidirectional semiconductor switch (such as thyristor), which may be operable to remain conductive independent of the magnitude of a load current conducted through the thyristor and to conduct the load current to and from the load during a single half-cycle. The dimmer switch comprises a power supply that conducts a charging current through the load in order to generate a supply voltage. The dimmer switch comprises a control circuit that controls a gate coupling circuit for rendering the thyristor conductive each half-cycle. The control circuit may provide a constant gate drive to the thyristor after the thyristor is rendered conductive each half-cycle.

Abstract: A two-wire load control device (such as, a dimmer switch) for controlling the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) includes a thyristor coupled between the source and the load, a gate coupling circuit coupled between a first main load terminal and the gate of the thyristor, and a control circuit coupled to a control input of the gate coupling circuit. The control circuit generates a drive voltage for causing the gate coupling circuit to conduct a gate current to thus render the thyristor conductive at a firing time during a half cycle of the AC power source, and to allow the gate coupling circuit to conduct the gate current at any time from the firing time through approximately the remainder of the half cycle, where the gate coupling circuit conducts approximately no net average current to render and maintain the thyristor conductive.

Abstract: A two-wire load control device (such as, a dimmer switch or an electronic switch) for controlling the power delivered from an AC power source to an electrical load includes a controllably conductive device for controlling the power to the load, a microprocessor operable to generate a control signal that is representative of whether the load should be controlled on or off, a capacitor operable to produce a supply voltage for powering the microprocessor, a power supply that charges the capacitor when the controllably conductive device is non-conductive, and a control circuit that receives the control signal from the microprocessor. The control circuit is operatively coupled to the controllably conductive device for maintaining the controllably conductive device non-conductive after the beginning of each half-cycle until the magnitude of the supply voltage exceeds a predetermined threshold.

Abstract: A load control device may control the amount of power provided to an electrical load utilizing a phase control signal that operates in a reverse phase control mode, a center phase control mode, and a forward phase control mode. A load control device may be configured to determine that the electrical load should be operated via a phase control signal operating in a forward phase-control mode. After determining to operate the electrical load via the phase control signal in the forward phase-control mode, the load control device may provide the phase control signal in a reverse phase-control mode for a predetermined period of time to the electrical load, for example, to charge a bus capacitor of the electrical load. Subsequently, the load control device may be configured to switch the phase control signal to the forward phase-control mode and provide the phase control signal in the forward phase-control mode to the electrical load.

Abstract: A remote control device may provide a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.

Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.

Abstract: If there is an interruption of power to an electrical load while the electrical load is operating at low end, the electrical load may not turn back on when power is restored. This undesired operation may be avoided by detecting the application of power to the electrical load, and automatically increasing the magnitude of a control signal being applied to the electrical load by a sufficient amount for a short period of time after power has been applied. This way, the electrical load may be turned back on to low end, instead of erroneously operating in an electronic off condition.

Abstract: A motorized roller tube for reeling and unreeling a flexible member between fully open and fully closed conditions operates with minimized sound level. A variable controller energizes a motor with a controllable RPM driving a gear reduction assembly. The motor has a speed versus torque characteristic which extends linearly from a high maximum RPM and low minimum torque, to a low minimum RPM and high maximum torque, and having a peak efficiency at a given RPM. The motor moves the flexible member between its fully open and fully closed positions at a motor speed less than the given peak efficiency RPM and less than 50% of its high maximum RPM, and at a motor efficiency which is less than 25% of the peak efficiency whereby the motor is intentionally operated in a high torque and low efficiency manner.

Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.
