Abstract: A recessed downlight fixture and method for installation is provided. The recessed downlight fixture can be installed in a retrofit application, after a ceiling is installed, through a pre-existing opening in that ceiling. Alternatively, a recessed downlight fixture according to a second embodiment can be installed before a ceiling is present. In either embodiment, the light source coupled to, for example, a heat sink, can be universally moved in three degrees of movement, rotationally, along a tilt axis, or further within the ceiling to increase or decrease the recess. All such universal adjustments can take place through and below the ceiling opening during or after installation.

Abstract: A veneer may be configured to be secured to a backlit button of a control device. A plate portion of the veneer may have one or more indicia machined therethrough. The indicia may define an open portion, a floating portion, and one or more ribs that suspend the floating portion. The one or more ribs may be configured to create an optical illusion that conceals the ribs from view relative to a user of the control device. The rib may define an upper surface that is recessed relative to a front surface of the veneer, and may define opposed sides that extend from a base of the rib to the upper surface. The sides may be tapered between the base and the upper surface, such that the upper surface is narrower than the base. The sides and the upper surface of the rib may be unfinished.

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 includes a load control device and a remote control for configuring and controlling operation of the load control device. The load control device and remote control may be mounted to an electrical wallbox. The system may be configured by associating the remote control with the load control device, and actuating a button on the remote control to configure the load control device. A second remote control device may be directly or indirectly associated with the load control device. The load control device and remote control may communicate via inductive coils that are magnetically coupled together. The remote control may be operable to charge a battery from energy derived from the magnetic coupling between the inductive coils. The load control device and remote control may include near-field communication modules that are operable to communicate wirelessly via near-field radiation.

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.

Abstract: A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may switch from controlling one characteristic of the electrical loads to controlling another characteristic of the electrical loads based on the position and/or orientation of one or more components of the load control device. Such a position and/or orientation may be manipulated by moving the one or more components relative to a base portion of the load control device. The load control device may be a wall-mounted device or a battery-powered remote control device.

Abstract: A method and light emitting diode (LED) illumination device comprising multiple emitter modules are provided. In one embodiment, the method includes bringing to a level insufficient to produce illumination the respective drive currents of all except one of multiple emission LED elements within respective first and second emitter modules for the duration of a measurement interval within respective first and second series of measurement intervals. The measurement intervals are interspersed with periods of illumination, and the first and second series of measurement intervals are separated by respective first and second offsets from a timing reference. An embodiment of an illumination device includes multiple emitter modules, where each emitter module includes multiple emission LED elements and one or more photodetectors. The illumination device further includes a lamp control circuit adapted to perform steps of the method.

Abstract: A load control system for controlling a plurality of lighting loads located in a space may be configured to track the location of one or more tracked devices. The load control system may comprise a system controller, lighting control devices, e.g., for controlling a plurality of lighting loads, and tracked devices. The tracked devices may each transmit beacon messages. The lighting control devices may receive the beacon message. The lighting control devices may measure a communication quality metric of each of the beacon messages, and process the measured communication quality metrics received over a period of time to determine a processed communication quality metric for the tracked device. The lighting control devices may transmit tracking data to the system controller. The system controller may determine a location of the tracked device. For example, the system controller may determine the location of the tracked device via trilateration.
