摘要： 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.

摘要： A backlit operating portion of a control device includes a veneer having indicia defining an open portion exposing a backlit component, a floating portion, and one or more ribs that suspend the floating portion. The rib defines an upper surface recessed relative to a front surface of the veneer, and opposed sides that extend from a base of the rib to the upper surface, such opposed sides tapered between the base and the upper surface, such that the upper surface is narrower than the base.

摘要： A load control device for controlling the amount of power delivered to an electrical load (e.g., an LED light source) comprises an isolated forward converter comprising a transformer, a controller, and a current sense circuit operable to receive a sense voltage representative of a primary current conducting through to a primary winding of the transformer. The primary winding is coupled in series with a semiconductor switch, while a secondary winding is adapted to be operatively coupled to the load. The forward converter comprises a sense resistor coupled in series with the primary winding for producing the sense voltage that is representative of the primary current. The current sense circuit receives the sense voltage and averages the sense voltage when the semiconductor switch is conductive, so as to generate a load current control signal that is representative of a real component of a load current conducted through the load.

摘要： A control device includes a moving portion, a magnetic element coupled to the moving portion, at least one magnetic sensing circuit responsive to magnetic fields, and at least one magnetic flux pipe structure. The magnetic element may comprise alternating positive and negative sections configured to generate a magnetic field. The magnetic element may be any shape, such as circular, linear, etc. The magnetic sensing circuit may be radially offset from the magnetic element, and the magnetic flux pipe structure may be configured to conduct the magnetic field generated by the magnetic element towards the magnetic sensing circuit. The magnetic element may generate the magnetic field in a first plane, and the magnetic sensing may be responsive to magnetic fields in a second direction that is angularly offset from the first plane. The magnetic flux pipe structure may redirect the magnetic field towards the magnetic sensing circuit in the second direction.

摘要： A control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The control device may be a wall-mounted device or a battery-powered remote control device. The feedback may indicate the amount of power delivered to the one or more electrical loads. The feedback may also indicate a low battery condition. The control device may include a light bar and/or one or more indicator lights for providing the feedback.

摘要： A control device may have a plurality of buttons that may be backlit to multiple levels, such as first, second, and third adjacent buttons positioned in order, and first, second, and third LEDs positioned to illuminate a respective button. The control device may be configured to illuminate the first LED to a first LED illumination intensity to illuminate the respective button to a first surface illumination intensity; illuminate the third LED to a second LED illumination intensity to illuminate the respective button to a second surface illumination intensity; and illuminate the second LED to a third LED illumination intensity to illuminate the respective button to the second surface illumination intensity. The third LED illumination intensity may be less than the second LED illumination intensity, which may be less than the first LED illumination intensity, and the second surface illumination intensity may be less than the first surface illumination intensity.

摘要： A load control system for controlling an electrical load may include a sensor, a remote control, and a load control device. The remote control may comprise a button and may be configured to wirelessly transmit a digital message in response to an actuation of the button. The load control device may be configured to control the electrical load, be responsive to the sensor, and/or be configured to be associated with the remote control. The load control device may be responsive to the digital message transmitted by the remote control if the remote control is associated with the load control device. The load control device may be configured to automatically operate in a first mode of operation if the remote control is not associated with the load control device, and automatically operate in a second mode of operation if the remote control is associated with the load control device.

摘要： A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.
