Abstract: A lighting relay panel may include lower-cost features or components related to improved safety and reliability. In some cases, the relay panel includes a power supply capable of protecting the panel from high-voltage and high-current transients. A microcontroller may determine a power interruption based on a zero-cross signal received from the power supply, and may also configure latching relays during the interruption. In some implementations, the relay panel includes a relay sense circuit that is capable of receiving actuation signals from multiple relays connected to different phases of a power signal, and the microcontroller may synchronize or repeat the actuations based on a signal from the relay sense circuit. The microcontroller may generate relay addresses based on the relay positions within the relay panel. In some cases, the relay panel may include isolation circuits that are capable of providing an isolated control signal having an improved voltage range.

Abstract: A method for configuring a wireless sensor of a lighting control network may include, providing, by a user, a sensor stimulus to cause the wireless sensor to wake-up from a reduced power operating mode. In the reduced power operating mode, a first radio configured to communicate using a first wireless communication protocol and a second radio configured to communicate using a second wireless communication protocol may be inoperative. The first radio may become operative upon the wake-up. The method may further include receiving, via the first radio, an activation message from a control device. The activation message may cause the wireless sensor to maintain operation of the first radio for a first specified period of time. The method may further include resuming, by the wireless sensor, operation in the reduced power operating mode after the first specified period of time. The wireless sensor may be a battery-powered wireless sensor.

Abstract: A light fixture includes a housing with a skylight aperture, and one or more louver blades spanning the skylight aperture. When open, the one or more movable louver blades block little of the light passing through the skylight aperture; in intermediate positions, the louver blades block a portion of the light; when closed, the louver blades block most light from passing through the skylight aperture. The light fixture also includes: a dimmable artificial light source configured to project artificial light toward the illuminated space; a light sensor that detects light illuminating the space; and a control unit that is integrated with the housing and communicates with the light sensor. The light sensor detects intensity and chromaticity information of the light illuminating the space. The control unit controls position of the louver blades and brightness and chromaticity of the dimmable artificial light source, in response to the light sensor.
