The plural lighting control devices include receiving units, controlling units, activating units, and power supply units, respectively and are coupled to the traffic control device by the same communication wire. The traffic control device simultaneously sends an activating signal to the plural lighting control devices via the communication wire. The receiving units receive the activating signal. The controlling units activate the activating units on the basis of the time condition from the reception of the activating signal to the activation of the activating units, set for the flashlights, respectively. When the power supply units are turned ON in an activated state of the activating units, respectively, the flashlights are lit by a lighting signal from the traffic control device, respectively. | 2019-12-26 |

The method includes at least: inputting group information into a respective light-emitting device, the group information to be inputted corresponds to a seat in a venue, on which the respective light emitting device to be positioned; and selectively controlling illuminating or extinguishing of groups of light-emitting devices, in accordance with the group information, to present an image over the plurality of light-emitting devices positioned on seats in the venue of an event during a particular period of a group-performance presentation. | 2019-12-26 |
20190394861 | Faceplate Remote Control Device for Use in a Load Control System - A faceplate remote control device may be attached to a wall-mounted mechanical light switch that has a toggle actuator. The faceplate remote control device may include a toggle indicator that detects operation of the toggle actuator of the mechanical switch. The toggle indicator may cause the generation of an indication of detected operation of the toggle actuator. The toggle indicator may comprise a sliding member that is configured to move with the toggle actuator. The toggle indicator may comprise an obstruction detection device that includes an infrared (IR) transmitter and an IR receiver. The faceplate remote control device may include a control circuit and a wireless communication circuit. The control circuit may be configured to cause the wireless communication circuit to transmit one or more messages in response to detecting operation of the toggle actuator of the mechanical switch. | 2019-12-26 |
20190394862 | SYSTEMS AND METHODS FOR OUTDOOR LUMINAIRE WIRELESS CONTROL - Systems and methods which leverage the wireless communication capability present in wireless-enabled luminaires where the lamps include a short-range wireless transceiver and can be controlled by a smart appliance. The wireless capability of a luminaire may be paired with a compatible wireless interface system (e.g., adapter system) that allows for control of the luminaire via plug-in or hard-wired photocontrols and wireless network lamp control nodes. An adapter system may be provided that replaces a standard wired receptacle of a luminaire. The adapter system may include a wired interface to the luminaire which provides power to the wireless adapter system. The wireless adapter system may include a receptacle interface that receives a plug of a control node, such as photocontrol or a networked control node. The wireless adapter system may also include a wireless interface circuit that communicates control, status or other data between the connected control device and the luminaire. | 2019-12-26 |
20190394863 | RETROFIT SMART HOME CONTROLLER DEVICE WITH POWER SUPPLY MODULE, CHARGER AND DOCK - A smart home controller device for controlling a lighting device, which operates with two wires of an electrical installation and can be installed in a standard electrical box and includes a first low power module, a charger module, a second low power module, a high power module and a wireless controller. The first low power module is used when the lighting device is a smart lighting device, and energizes the charger module, which provides power to a battery of the wireless controller. The wireless controller wirelessly sends and receives signals from the smart lighting device to control its operation and monitor its status. The second low power module is used when the lighting device is a conventional lighting device and provides power to the wireless controller when the lighting device is ON. The high power module is used to control the switching ON, OFF and dimming of the conventional lighting device. | 2019-12-26 |
