Disclosed is a lighting effect directing method of a receiving device. The lighting effect directing method of a receiving device includes determining coordinates of the receiving device at a seat based on seat information thus received, receiving and storing object data including a predefined direction shape and at least one expression level set to correspond to a size of the direction shape, and predefined color data, receiving a control packet including object information indicating the direction shape, an object origin of the direction shape, and the at least one expression level, and color information indicating a light emission color, determining a location relationship between the object origin and the determined coordinates of the receiving device, based on the object information, and performing a corresponding light emission operation such that the direction shape is expressed at the at least one expression level, based on the location relationship and the color information.

A method of joining a node device into a wireless network, the network created by a coordinator device and comprising a plurality of node devices divided into a number of groups. The method performed by one of the node devices and comprises the steps of: receiving a beacon message from the coordinator device at a first time instant; obtaining a group label for the node device based on the number of groups; determining a joining interval for determining a joining time instant for the node device; and transmitting a joining request to the coordinator device, at a joining time instant determined based on a starting reference time instant plus a joining period. The transmission step is repeated until an association response is received from the coordinator device, and a joining period for determining a joining time instant of a subsequent one of two consecutive transmissions is reduced comparing to a joining period for determining the joining time instant of the previous one of the two consecutive transmissions.

A system (100) comprising one or more light sources (110) for illumination; an array of active antennas (120) configured to detect contextual information; and a controller (130) configured to obtain the contextual information from the array of active antenna; and control the one or more light sources based on the contextual information; wherein the array of active antennas (120) is shared with a co-located MIMO communication system, and the contextual information is related to one or more objects in an illumination area covered by the one or more light sources (110).

A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may switch from controlling one characteristic of the electrical loads to controlling another characteristic of the electrical loads based on the position of one or more components of the load control device. Such a position may be manipulated by moving the one or more components relative to an idle position of the load control device. The load control device may be a wall-mounted device or a battery-powered remote control device.

Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.

A light system for a vehicle using an eight-zone controller for controlling the lights. The eight-zone controller can maintain eight independent signal zones, or two or more zones can be grouped together. The eight-zone controller is configured with splitter hubs and second tier splitter hubs to increase the quantity of lights included in the system.

An LED light fixture includes one or more optical transceivers that have a light support having a plurality of light emitting diodes and one or more photodetectors attached thereto, and a processor in communication with the light emitting diodes and the one or more photodetectors. The processor is constructed and arranged to generate a communication or data transfer signal.

Power receptacle control circuitry includes load switching circuitry, communications circuitry, sensor circuitry, processing circuitry, and a memory. The sensor circuitry includes a light sensor. The processing circuitry is coupled to the load switching circuitry, the communications circuitry, the sensor circuitry, and the memory. The memory includes instructions, which, when executed by the processing circuitry cause the power receptacle control circuitry to selectively deliver power to a load via the load switching circuitry, detect a modulated light signal via the light sensor, and join a group of devices based on the modulated light signal.

The present disclosure provides LED array systems with a control system for arrays of LED array luminaires that allows for display of images or light patterns across and array of luminaires over a low bandwidth control protocol.

An apparatus and method allow end users to interactively create complex lighting patterns by remote control. Applications include decorative lighting, landscape lighting, signage, or advertising platforms. A lighting control system can be equipped with sensors that can receive remote control signals from a variety of different sources, and route the control signals to modulate receptacles coupled to different lighting circuits, thereby independently controlling multiple light arrays to achieve separate light patterns, or to coordinate different lighting effects. Interactive remote control can be provided via a mobile computing device such as a smart phone running a customized program. In one embodiment, the remote control device communicates selections to a Bluetooth?-equipped speaker to produce sound-controlled lighting effects.
