    Abstract: Methods and systems may be used to control the output parameters of one or more light sources (e.g., discrete-spectrum light sources) based on fixture capability information. Fixture capability information may be obtained using a configuration tool. The fixture capability information may be determined by the configuration tool, and the fixture capability information determined by the configuration tool may be stored and/or processed. The fixture may have a memory for storing the fixture capability information. The fixture capability information may also be stored in a remote network device. A system controller may obtain the fixture capability information from the fixture or the remote control device. The system controller may generate control instructions based on the fixture capability information and send the control instructions to the fixtures.

    Abstract: A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).

    Abstract: Illumination devices with improved color mixing optics are disclosed herein for mixing the colors produced by a multi-colored LED emitter module to produce uniform color throughout the entire beam angle of the output light beam, along with smoother edges and improved center beam intensity. Embodiments disclosed herein include a unique arrangement of multi-color LEDs within an emitter module, a unique exit lens with different patterns of lenslets on opposing sides of the lens, and other associated optical features that thoroughly mix the different color components, and as such, provide uniform color across the output beam exiting the illumination device. Additional embodiments disclosed herein include a unique arrangement of photodetectors within the primary optics structure of the LED emitter module that ensure the optical feedback system properly measures the light produced by all similarly colored emission LEDs.

    Abstract: A coupling for a roller tube of a window treatment system may include a body and/or one or more compliant members. The body may include a bore through a rotational axis of the coupling. The body may be configured to be received within the roller tube of the window treatment system. The body may define an outer surface. One or more compliant members may extend at an oblique angle from the outer surface of the coupling. The one or more compliant members may be configured to engage a smooth inner surface of the roller tube. The use of compliant members may enable a rigid connection of the coupling to the smooth inner surface of the roller tube surface, without the use of fasteners.

    Abstract: A control device configuration system may receive, store, process, and/or display control device configuration information. The control device configuration system may filter the control device configuration information based on user selections of configuration options for configuration parameters. The control device configuration system may identify compatible and incompatible configuration options for various configuration parameters. The control device configuration system may allow selections of the incompatible configuration options. The control device configuration system may adjust how it filters the control device configuration information based on the selections of the incompatible configuration options. The control device configuration system may implement a configuration model that includes configuration parameter groups for efficient evaluation of user selections.

    Abstract: A power converter circuit may include a control circuit configured to generate a drive signal for rendering a semiconductor switch conductive and non-conductive to generate a bus voltage across a bus capacitor. The control circuit may adjust a minimum operating period of the drive signal to a first value when an output power of the power converter circuit is greater than a first threshold and to a second value when the output power is less than a second threshold. The control circuit may comprise a comparator that generates the drive signal in response to a sense voltage and a threshold voltage. When operating in a standby mode, the control circuit may adjust a magnitude of the threshold voltage based on an instantaneous magnitude of an alternating-current line voltage received by the power converter circuit, such that an input current drawn by the power converter circuit is sinusoidal.
