Publication number: 20200036296Abstract: A load control device is configured to generate a control signal having a desired magnitude for controlling a load regulation device adapted to control the power delivered to an electrical load. The load control device may comprise a control terminal arranged to provide the control signal to the load regulation device, a communication circuit for generating the control signal, and a control circuit configured to generate an output signal that is provided to the communication circuit. The communication circuit may be characterized by non-linear operation. The control circuit may adjust the magnitude of the output signal in response to the difference between the magnitude of the control signal and the desired magnitude to adjust the magnitude of the control signal towards the desired magnitude.

Publication number: 20190124750Abstract: A load control device adapted to be coupled between an AC power source and an electrical load for controlling the power delivered to the load includes a controller, an actuator for turning the electrical load on and off, an occupancy detection circuit, and an ambient light detector. The load control device automatically turns on the electrical load in response to the presence of an occupant only if the detected ambient light is below a predetermined ambient light level threshold. After first detecting the presence of an occupant, the load control device monitors actuations of the actuator to determine whether a user has changed the state of the load. The load control device automatically adjusts the predetermined ambient light level threshold in response to the user actuations that change the state of the load.Type: ApplicationFiled: December 17, 2018Publication date: April 25, 2019Applicant: Lutron Electronics Co., Inc.Inventors: Ryan S.

Publication number: 20170105255Abstract: A load control device for controlling the amount of power delivered from an AC power source to an electrical load is operable to conduct enough current through a thyristor of a connected dimmer switch to exceed rated latching and holding currents of the thyristor. The load control device comprises a controllable-load circuit operable to conduct a controllable-load current through the thyristor of the dimmer switch. The load control device disables the controllable-load circuit when the phase-control voltage received from the dimmer switch is a reverse phase-control waveform. When the phase-control voltage received from the dimmer switch is a forward phase-control waveform, the load control device is operable to decrease the magnitude of the controllable-load current so as to conduct only enough current as is required in order to exceed rated latching and holding currents of the thyristor.Type: ApplicationFiled: December 20, 2016Publication date: April 13, 2017Inventors: Christopher James Salvestrini, Ryan S.
