  • Patent number: 12376206
    Abstract: A control device may comprise a plurality of buttons, a plurality of light sources located behind the respective buttons and configured to illuminate the buttons, a light detector circuit configured to measure an ambient light level around the control device, and/or a control circuit configured to control the light sources to adjust surface illumination intensities of the respective buttons in response to the measured ambient light level. Each button may comprise indicia indicating a function of the button. The control circuit set the first button as active and the second button as inactive in response to an actuation of the first button. The control circuit may, based on the measured ambient light level, control the light sources to illuminate the first button to an active surface illumination intensity, and to illuminate the second button to an inactive surface illumination intensity that is less than the active surface illumination intensity.

  • Publication number: 20240363295
    Abstract: A control device configured for use in a load control system to control an external electrical load may provide simple feedback regarding the operation of the control device. For example, the control device may comprise a base portion configured to be mounted to an electrical wallbox or over a mechanical switch, and a control unit connected to the base portion. The control unit may comprise a rotation portion rotatable with respect to the base portion, an actuation portion, and a light source. The control unit may be configured to control the light source to illuminate at least an illuminated portion of the actuation portion in response to actuations of the rotation portion and the actuation portion. In addition, the control unit may provide a limit indication on the illuminated portion by blinking the illuminated portion when the electrical load has reached a limit.

  • Publication number: 20240334578
    Abstract: A load control system may include control devices capable of being associated with each other at one or more locations for performing load control. Control devices may include control-source devices and/or control-target devices. A location beacon may be discovered and a unique identifier in the location beacon may be associated with a unique identifier of one or more control devices. Upon subsequent discovery of the location beacon, the associated load control devices may be controlled. The beacons may be communicated via radio frequency signals, visible light communication, and/or audio signals. The visible light communication may be used to communicate other types of information to devices in the load control system. The visible light communication may be used to identify link addresses for communicating with load control devices, load control instructions, load control configuration instructions, network communication information, and/or the like.
