Abstract: A load control device (e.g., a switching device) for controlling power delivered from an AC power source to an electrical device (e.g., a lighting load) may be configured to detect that a relay is stuck closed and attempt to fix the relay. The relay of the load control device may be adapted to be coupled between the source and the electrical device to control the power delivered to the electrical device so as to generate a switched-hot voltage. The load control device may comprise a detect circuit configured to generate a detect signal indicating a magnitude of the switched-hot voltage, and a control circuit configured to monitor the detect signal. The control circuit may be configured to determine that the relay is stuck closed in response to the detect signal, and to control the relay in order to attempt to fix the relay by repeatedly closing and opening the relay.

Abstract: A load control device may be configured to turn on lighting loads to obtain a fast turn-on time that may be substantially consistent across lighting loads that have different load voltages. The load control device may comprise a power converter circuit configured to produce a voltage across a capacitor, and a control circuit configured to control the power converter circuit to generate the voltage across the capacitor. The control circuit may determine a learned voltage from the magnitude of the voltage across the capacitor. For example, the control circuit may measure the magnitude of the voltage and store the measured voltage as the learned voltage. The control circuit may determine an operating parameter for the power converter circuit as a function of the learned voltage, and control the power converter circuit according to the operating parameter to charge the capacitor until the magnitude of the voltage exceeds a threshold.

Abstract: A control module attached to a lighting fixture and having a front cover portion may comprise one or more sensors, such as a daylight and/or occupancy sensor, for sensing information through the front cover portion. The control module may have a main printed circuit board (PCB) that extends from a front side to a rear side of the control module, and a sensor PCB perpendicular to the main PCB to enable at least one sensor attached to the sensor PCB to face the front side of the control module. The main PCB may comprise a wireless communication circuit and an antenna for communicating radio frequency (RF) signals, wherein at least a portion of the antenna is located within a plastic lip of the front cover portion of the control module. The control module may further have a conductive enclosure to reduce radio-frequency interference noise from coupling into the antenna.

Abstract: A load control device for controlling power delivered from a power source to an electrical load may comprise a control circuit configured to control the load regulation circuit to control the power delivered to the electrical load. The control circuit may be configured to operate in an AC mode when an input voltage is an AC voltage and in a DC mode when the input voltage is a DC voltage. The control circuit may be configured to disable the power converter in the DC mode. The control circuit may be configured to render a controllable switching circuit conductive in the AC mode, and non-conductive in the DC mode. The rectifier circuit may be configured to rectify the input voltage to generate a rectified voltage when the input voltage is an AC voltage, and to pass through the input voltage when the input voltage is a DC voltage.

Abstract: A load control system may include control devices for controlling power provided to an electrical load. The control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. The control devices may include a load control discovery device capable of sending discovery messages configured to discover control devices within a location. The discovered control devices may be organized by signal strength and may be provided to a network device to enable association of the discovered control devices within a location. The discovery messages may be transmitted within an established discovery range. The discovery range may be adjusted to discover different control devices. Different control devices may be identified as the load control discovery device for discovering different control devices.

Abstract: A load control device may control the amount of power provided to an electrical load utilizing a phase control signal that operates in a reverse phase control mode, a center phase control mode, and a forward phase control mode. A load control device may be configured to determine that the electrical load should be operated via a phase control signal operating in a forward phase-control mode. After determining to operate the electrical load via the phase control signal in the forward phase-control mode, the load control device may provide the phase control signal in a reverse phase-control mode for a predetermined period of time to the electrical load, for example, to charge a bus capacitor of the electrical load. Subsequently, the load control device may be configured to switch the phase control signal to the forward phase-control mode and provide the phase control signal in the forward phase-control mode to the electrical load.

Abstract: A load control system, such as a lighting control system, may be configured to control a first electrical load in response to a sensed operational characteristic of a second electrical load. The load control system may include a load control device electrically connected to the first electrical load, and a load-sensing remote control device that is configured to sense an operational characteristic of the second electrical load. The load-sensing remote control device may be configured to communicate with the load control device via wireless communication. The load-sensing remote control device may be configured to transmit messages to the load control device in response to sensing a change in the operational characteristic of the second electrical load. The load control device may be configured to, upon receiving messages from the load-sensing remote control device, control an amount of power that is delivered to the first electrical load.
