A lighting device included in a network of a plurality of lighting devices includes: a lighting unit; a communication interface configured to receive a control signal generated at an external device directly from the external device or by way of another lighting device in the network, depending on a connection relationship between the plurality of lighting devices; a memory configured to store information about the lighting device; and a controller configured to, according to the control signal and the information about the lighting device, selectively perform one of controlling an operation of the lighting unit and relaying the control signal to at least one other lighting device in the network through the communication interface to control an operation of at least one target lighting device included in the network. Here, the at least one other lighting device itself may be the at least one target lighting device.

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. The control signals can independently energize localized groups of lamps to provide enhanced lighting effects, while using significantly less wire material. 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.

A lighting fixture includes a solid-state light source, communications circuitry, and control circuitry coupled to the communications circuitry and the solid-state light source. The control circuitry is configured to receive a message from a neighboring device via the communications circuitry, the message indicating the detection of an occupancy event by the neighboring device. Further, the control circuitry is configured to adjust a light output provided by the solid-state light source based on a neighbor ranking of the neighboring device, wherein the neighbor ranking indicates a number of intermediate devices located between the lighting fixture and the neighboring device.

Embodiments are provided for a lighting system and a method of installing a lighting system. According to certain aspects, a driver box is configured with a plurality of drivers secured therein. A series of wired connections can couple the plurality of drivers to a plurality of luminaires and can conduct electric power from the plurality of drivers to power the plurality of luminaires. According to aspects, the driver box and its plurality of drivers are located remote from the plurality of luminaires to enable efficient maintenance of the lighting system.

A rain gutter illumination system having a cover for attaching to a rain gutter with an aperture along the substantial length of the cover, and opposing recesses for retaining a decorative insert. When the decorative insert is inserted in the cover, it is held in place by the recesses, and a light source and optional diffusing panel may be arranged in the cover so that the light source projects light through the aperture of the illuminable surface. The light source may be remotely controllable using a wireless remote control device, such as a smart phone over a network connection.

A load control system for controlling an electrical load may include a sensor, a remote control, and a load control device. The remote control may comprise a button and may be configured to wirelessly transmit a digital message in response to an actuation of the button. The load control device may be configured to control the electrical load, be responsive to the sensor, and/or be configured to be associated with the remote control. The load control device may be responsive to the digital message transmitted by the remote control if the remote control is associated with the load control device. The load control device may be configured to automatically operate in a first mode of operation if the remote control is not associated with the load control device, and automatically operate in a second mode of operation if the remote control is associated with the load control device.

A luminaire for use in a lighting apparatus comprising a plurality of luminaires and a computerized device comprising a plurality of lights and a controller configured to communicate with the computerized device, and coupled to the plurality of lights, and configured to operate the luminaire to emit source light, the source light being characterized by a dominant source light wavelength that varies with time within a range from 390 nanometers to 750 nanometers. The controller is configured to operate the plurality of lights to emit a source light with a different dominant source light wavelength than the source light of another luminaire in the lighting apparatus and combine with the source light emitted by the at least one other luminaire to form a combined light at a distance from the luminaire, receive a lighting scenario from the computerized device, and operate the luminaire responsive to the lighting scenario.

Enhancements to ornamental or holiday lighting are disclosed including remote control ornamental illumination with color pallet control whereby a user can vary the color/intensity/appearance of an individual bulb or entire light string by selecting the electronic address of the bulb and selecting its attribute. Further disclosures include: motion responsive lights which respond to sensed movement, gesture controlled lights, adjustable white color/white led sets, connectable multi-function lights, controller to sequence lights to music or other input source, rotating projection led light/tree top/table top unit, and remote controlled sequencing icicle lights and ornament lighting system.

In a visual light communication (VLC) or other light based positioning system, a mobile device can detect modulated light emitted by one or more localized artificial lighting devices to obtain an identification (ID) label or code of each lighting device, e.g. that is visible in an image captured by the mobile device camera. The mobile device uses the detected ID code for a lookup in a self-stored or remotely stored table that associates light-source-location information with ID codes, to obtain an estimate of mobile device position. To mitigate against hacking by a third party detecting the ID codes and observing locations to compile its own lookup table, the disclosed examples dynamically alter the assignments of particular ID codes to the lighting devices, while minimizing potential disruption of position determination service for mobile devices due to the changes to ID code assignments.

Embodiments are included for providing an energy efficient lighting system that includes one or several luminaires. According to certain aspects, when an area covered by the luminaires is vacant, the light level in the area is measured while the luminaires are on and set to a low dim level. The measured light level is used to approximate the amount of natural light in the area and when the measured light level exceeds a predetermined nonzero light level, the luminaires are turned off for a certain time period. Once the time period expires, the light level is measured again to approximate the amount of natural light present in the area.
