  • Patent number: 10958187
    Abstract: A load control device for controlling the power delivered from an AC power source to an electrical load includes a thyristor, a gate coupling circuit for conducting a gate current through a gate of the thyristor, and a control circuit for controlling the gate coupling circuit to conduct the gate current through a first current path to render the thyristor conductive at a firing time during a half cycle. The gate coupling circuit is able to conduct the gate current through the first current path again after the firing time, but the gate current is not able to be conducted through the gate from a transition time before the end of the half-cycle until approximately the end of the half-cycle. The load current is able to be conducted through a second current path to the electrical load after the transition time until approximately the end of the half-cycle.

  • Patent number: 10958186
    Abstract: A load control device (such as, a dimmer switch) for controlling the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) includes a thyristor (such as, a triac) coupled between the source and the load, a gate coupling circuit arranged to conduct current through a gate terminal of the thyristor, and a control circuit configured to control the gate coupling circuit. The control circuit may control the gate coupling circuit to conduct a pulse of current through the gate terminal to render the thyristor conductive at a firing time during a present half cycle of the AC power source, and allow the gate coupling circuit to conduct at least one other pulse of current after the firing time during the present half cycle.

  • Publication number: 20210045221
    Abstract: Systems and methods described herein provide examples of an electrical panel (e.g., a modular electrical panel) that is configured to control a plurality of electrical loads. The electrical panel may include a control circuit, memory, a communication circuit, and an alternating current (AC) line feed and/or a direct current (DC) line feed. The electrical panel may also include a plurality of power supplies and a plurality of control modules, where more than one control module is associated with each of the plurality of power supplies. Each control module may configured to receive DC power from the associated power supply and provide an output voltage to at least one electrical load. The electrical panel provides flexibility as to whether each stage of conversion, regulation, and/or control is performed at a control module located within the electrical panel or performed at an accessory module located at an electrical load.

  • Publication number: 20210045210
    Abstract: If there is an interruption of power to an electrical load while the electrical load is operating at low end, the electrical load may not turn back on when power is restored. This undesired operation may be avoided by detecting the application of power to the electrical load, and automatically increasing the magnitude of a control signal being applied to the electrical load by a sufficient amount for a short period of time after power has been applied. This way, the electrical load may be turned back on to low end, instead of erroneously operating in an electronic off condition.

  • Publication number: 20210045202
    Abstract: A multiple location load control system may comprise a main load control device and an accessory load control device. The main load control device may control an amount of power delivered to an electrical load from an AC power source using a control circuit and a controllably conductive device. The accessory load control device may be coupled to the main load control device via an accessory terminal. The accessory load control device may detect a user input for changing a characteristic of the electrical load and may send a signal to the main load control device indicating the user input. The main load control device may detect a pattern of the signal based on a threshold and further determine the user input in response to the detected pattern. The main load control device may adjust the threshold based on line/load conditions of the multiple location load control system.

  • Patent number: 10915134
    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.

  • Patent number: 10904976
    Abstract: A controllable lighting device may utilize a controllable impedance circuit to conduct a load current through an LED light source. The controllable impedance circuit may be coupled in series with a first switching device, which may be rendered conductive and non-conductive via a pulse-width modulated signal to adjust an average magnitude of the load current. The controllable lighting device may further comprise a control loop circuit that includes a second switching device. The second switching device may be rendered conductive and non-conductive in coordination with the first switching device to control when a feedback signal is provided to the control loop circuit and used to control the LED light source. The control loop circuit may be characterized by a time constant that is significantly greater than an operating period of the load current.
