Disclosed embodiments provide a luminaire device including a power supply, and a three-way light module installed within a housing. The device includes an input end which is connected to the power grid, and an output end is connected to a three-way LED light module through the power supply and a control module, and an LED driver. The group corresponds to the series connection current module. The device also includes a dimmer, the output of the dimmer is connected to the power input of the lamp, and the power output is passed through a signal detection unit. A centralized control unit such as a microcontroller receives the adjustable signal of the dimmer, and the controller controls the current modules of the 3 LED modules. This enabled the feature of precise adjustments of brightness and correlated color temperature (CCT) of the device.

Lighting control systems may be commissioned for programming and/or control with the aid of an autonomous mobile device. Design software may be used to create a floor plan of how the lighting control system may be designed. The design software may generate floor plan identifiers for each lighting fixture, or group of lighting fixtures. During commissioning of the lighting control system, the autonomous mobile device may be used to help identify the lighting devices that have been installed in the physical space. The autonomous mobile device may receive a communication from each lighting control device that indicates a unique identifier of the lighting control device. The unique identifier may be communicated by visible light communication (VLC) or RF communication. The unique identifier may be associated with the floor plan identifier for communication of digital messages to lighting fixtures installed in the locations indicated in the floor plan identifier.

A wall-mountable remote control device may be installed in place of an existing light switch and may be configured to transmit wireless signals to an electrical load device, such as a screw-in light-emitting diode (LED) lamp, to provide control of the electrical load device. The remote control device may comprise an air-gap switch adapted to be electrically coupled in series between a power source and the controllable light source, but may not comprise a bidirectional semiconductor switch for controlling the amount of power delivered to the electrical load device using a phase-control dimming technique. The remote control device may have a low-profile enclosure that is smaller than an enclosure of a standard dimmer switch, and thus may be easier to install in an electrical wallbox. The remote control device may comprise two parts including an air-gap switch device and a wireless communication device mounted to the air-gap switch device.

A system is configured to obtain locations of a mobile device (1) and obtain presence detection information. The locations are determined using visible light signals and dead reckoning information recorded at different moments. The presence detection information indicates presence detected using presence sensor devices (31, 32) at the different moments. The system is further configured to obtain sensor locations and sensor fields of view, determine sensor orientations based on the locations of the mobile device, the sensor locations and the presence detection information, and determine a sensor coverage area (61, 62), comprising gaps in the sensor coverage area, based on the sensor locations, the sensor orientations and the sensor fields of view. The system is also configured to determine one or more parameters for presence detection based on the gaps in the sensor coverage area and output the parameters or a presence detection result which has been determined using the parameters.
