Abstract: Lighting control systems may be commissioned for programming and/or control with the aid of a mobile device. Design software may be used to create a floor plan of how the lighting control system may be designed. The design software may generate floor plan identifiers for each lighting fixture, or group of lighting fixtures. During commissioning of the lighting control system, the mobile device may be used to help identify the lighting devices that have been installed in the physical space. The mobile device may receive a communication from each lighting control device that indicates a unique identifier of the lighting control device. The unique identifier may be communicated by visible light communication (VLC) or RF communication. The unique identifier may be associated with the floor plan identifier for communication of digital messages to lighting fixtures installed in the locations indicated in the floor plan identifier.

Abstract: The remote control device may provide feedback via the status indicator that indicates the present intensity level of a lighting device responsive to the remote control device. The remote control device may provide feedback to indicate a first present intensity level of a first lighting device when the command is a first command type, and a second present intensity level of a second lighting device when the command is a second command type. When the first command type is a raise command and the second command type is a lower command, the first present intensity level may be less than the second present intensity level. In addition, the first lighting device may be a lighting device responsive to the remote control device with a lowest present intensity level and the second lighting device may be a lighting device responsive to the remote control device with a highest present intensity level.

Abstract: A system includes a window treatment adjacent to a window of a room. At least one motor drive unit is associated with the window treatment, for varying the position of the window treatment. A sensor measures a light level (e.g., an outdoor light level) at the window. A controller provides signals to the motor drive unit to automatically adjust the position of the window treatment so as to control a penetration distance of sunlight into the room when the window treatment is partially opened. The controller is configured to position the window treatment in a bright override position if the measured light level is at least a bright threshold value. The controller is configured to select the bright threshold value from among at least two predetermined values. The selection depends on an angle of incidence between light rays from the sun and a surface normal of the window.

Abstract: A sensor may detect glare from a recorded image and a shade position of a motorized window treatment may be controlled based on the position of the detected glare in the image. A luminance of a pixel may be calculated in an image and a glare condition may be detected based on the luminance of the pixel. For example, the sensor may start at a first pixel in a bottom row of pixels and step through each of the pixels on the bottom row before moving to a next row of pixels. When the sensor detects a glare condition, the sensor may cease processing the remaining pixels of the image. The sensor may calculate a background luminance of the image by reordering the pixels of the image from darkest to lightest and calculating the luminance of a pixel that is a predetermined percentage from the darkest pixel.

Abstract: A lighting device may include a light source, a plurality of drive circuits, and a control circuit. The light source may include a plurality of emitter circuits that are configured to emit light. The light source may include a first emitter circuit that is configured to emit light at a first color (e.g., color temperature), a second emitter circuit is configured to emit light at a second color (e.g., color temperature), and a third emitter circuit is configured to emit light at a third color (e.g., color temperature). The first, second, and third colors (e.g., color temperatures) may be on a color curve, such as a color temperature curve like the black body locus. The control circuit may be configured to control the amount of power delivered to no more than two emitter circuits to emit light when controlling the light emitted by the light source to the target intensity.

Abstract: A control device configured for use in a load control system to control one or more electrical loads may comprise an actuation member having a front surface defining a touch sensitive surface configured to detect a point actuation along at least a portion of the front surface, a touch sensitive circuit, and a control circuit. The touch sensitive device may comprise one or more receiving capacitive touch pads located behind the actuation member and arranged in a linear array adjacent to the touch sensitive surface. The control circuit may be configured to operate using different filtering techniques based on the state/mode of the control device and/or based on whether the positions of point actuations by a user along the touch sensitive surface indicate a fine tune or gross adjustment by the user. For example, the control circuit may generate an output signal using light/no filtering or using heavy filtering.

Abstract: A smart lighting device may be configured to be controlled in response to control instructions in messages and/or phase-control signals. The smart lighting device may determine whether to respond to the phase-control signal or the control instructions in messages. The smart lighting device may be configured to recognize whether it is electrically connected to a smart load control device or a non-smart load control device. A load control device may determine whether it is electrically connected to a mixed circuit or a non-mixed circuit. When the load control device determines that the circuit is a mixed circuit, the load control device may transmit phase-control signals and control instructions in messages at the same time. The load control device may determine that a smart lighting device has been added (e.g., electrically connected) to the circuit it is electrically connected to.

Abstract: A load control device for controlling the intensity of a lighting load, such as a light-emitting diode (LED) light source, may include a power converter circuit operable to receive a rectified AC voltage and to generate a DC bus voltage, a load regulation circuit operable to receive the bus voltage and to control the magnitude of a load current conducted through the lighting load, and a control circuit operatively coupled to the load regulation circuit for pulse width modulating or pulse frequency modulating the load current to control the intensity of the lighting load to a target intensity. The control circuit may control the intensity of the lighting load by pulse width modulating the load current when the target intensity is above a predetermined threshold and control the intensity of the lighting load by pulse frequency modulating the load current when the target intensity is below the predetermined threshold.

Abstract: A wall-mountable remote control device may be installed in place of an existing light switch and may be configured to transmit wireless signals to an electrical load device, such as a screw-in light-emitting diode (LED) lamp, to provide control of the electrical load device. The remote control device may comprise an air-gap switch adapted to be electrically coupled in series between a power source and the controllable light source, but may not comprise a bidirectional semiconductor switch for controlling the amount of power delivered to the electrical load device using a phase-control dimming technique. The remote control device may have a low-profile enclosure that is smaller than an enclosure of a standard dimmer switch, and thus may be easier to install in an electrical wallbox. The remote control device may comprise two parts including an air-gap switch device and a wireless communication device mounted to the air-gap switch device.
