  • Patent number: 11924948
    Abstract: A lighting control system for controlling a cumulative light emitted by a lighting fixture may comprise a light-emitting diode (LED) driver comprising an output for conducting an output current, and a control module electrically coupled to the output of the LED driver for receiving the output current. The LED driver may regulate the magnitude of the output current towards a target current, and may be characterized by a low-end intensity. The control module may be coupled to a first LED light source of the LED light sources. The control module may receive a command including a requested intensity and control the magnitude of a first LED current through the first LED light source. The control module may control the cumulative light output of the lighting fixture below the low-end intensity of the LED driver by diverting a portion of the output current away from the first LED light source.

  • Publication number: 20240005778
    Abstract: A remote control device having capacitive touch controls may be configured to enter a sleep state (or mode). For example, the remote control device may be configured to enter the sleep state upon expiration of an interval of time since a most recent button press. The remote control may be configured to awaken from the sleep state when one or more portions of a housing of the remote control are deflected, for example, when a user grasps the remote control to actuate one or more of the capacitive touch controls. For example, the remote control device may include a switch. The switch may include a carbon structure that may be configured to contact an open circuit pad on a circuit board to close the corresponding circuit when the housing is deflected and awaken the remote control device from the sleep state.

  • Publication number: 20230319962
    Abstract: A method for controlling an amount of power delivered to an electrical load may include controlling an average magnitude of a load current towards a target load current that ranges from a maximum-rated current to a minimum-rated current in a normal mode, and controlling the average magnitude of the load current below the minimum-rated current in a burst mode. The burst mode may include at least one burst-mode period that comprises a first time period associated with an active state and a second time period associated with an inactive state. During the burst mode, the method may include regulating a peak magnitude of the load current towards the minimum-rated current during the active state, and stopping the generation of at least one drive signal during the inactive state to control the average magnitude of the load current to be less than the minimum-rated current.

  • Publication number: 20230247738
    Abstract: A load control device for an electrical load is configured to operate in a normal mode and a burst mode to adjust the amount of power delivered to the electrical load. The load control device comprises a control circuit that operates in the normal mode to regulate an average magnitude of a load current conducted through the load between a maximum rated current and a minimum rated current. During the normal mode, the control circuit controls the operating period of a load regulation circuit between a high-end operating period and a low-end operating period. The control circuit operates in the burst mode to regulate the average magnitude of the load current below the minimum rated current. During the burst mode, the control circuit adjusts the low-end operating period to be less than or equal to a minimum on time of the load regulation circuit.

  • Publication number: 20220239518
    Abstract: An energy control network may include a number of load control devices, such as dimmer switches, multi-button selector switch, occupancy sensors, and remote controllers, among others. These load control devices may be configured for wireless communication. Other wireless devices, such as laptops, tablets, and “smart” cellular phones may be configured to communicate with the load control devices of the energy control network. The load control devices and the other wireless communication devices may also be configured for Near Field Communication (NFC). NFC may be used to provide a load control device with its initial default configuration and/or an application specific configuration. Also, NFC may be used to transfer a configuration from one load control device that may have become faulty, to a replacement load control device. And NFC may be used to provide and trigger commands that may cause a load control load device to operate in a predetermined manner.
