Apparatus, systems, and methods for controlling light output in a lighting system based on defined light profiles are provided. In one example implementation, a light fixture can include a first light emitting diode (LED) array having one or more LED light sources and a second LED array having one or more LED light sources. The light fixture can include a power circuit configured to provide power to the first LED array and the second LED array according to a power distribution among the first LED array and the second LED array. The light fixture can include one or more control devices configured to control the power circuit to adjust the power distribution among the first LED array and the second LED array based at least in part on a signal indicative of a real time clock and a defined light profile associated with a user identified to be present in a space illuminated by the light fixture.

Lighting units, systems, and methods are described herein for determining whether occupancy detections are legitimate or not. Methods and systems are further described herein for powering down a network of power over ethernet (PoE) components.

A lighting setting apparatus which is used to set lighting modes in a plurality of luminaires installed in a space includes: a storage which stores a lighting setting image indicating the entirety of an illumination area of the luminaires in the predetermined space and luminaire position information indicating the positions of the luminaires in the space; an input receiver which receives a user input regarding use of the lighting setting image; and a lighting setter which obtains the target pixel values of target pixels that are of the lighting setting image for which the input regarding the use has been received and that are located correspondingly to the positions of the luminaires indicated by the luminaire position information, determines, based on the obtained target pixel values, a lighting setting value for at least one of dimming or toning of the luminaires, and outputs the lighting setting value.

A lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors. The system also has a data communication network. Some number of the intelligent lighting system elements, including at least two of the lighting devices, also support wireless communication with other non-lighting-system devices at the premises. Each such element has a communication interface system configured to provide a relatively short range, low power wireless data communication link for use by other non-lighting-system devices at the premises in proximity to the respective intelligent system element. Also, in such an element, the processor is configured to control communications via the communication interface system so as to provide access to the data network and through the data network to the wide area network outside the premises for non-lighting related communications of the other non-lighting-system devices.

A lighting control system of the type including an electronic device with a processor, memory, wireless communication capability and a user interface may be used. A controller may be used with a receiver to receive wireless communication from the electronic device and an output terminal with at least one lighting array in electrical communication with the output terminal of the controller. A power supply may be provided in electrical communication with the controller thereby providing electrical power to the controller and the lighting array. Software on the electrical device may be used providing a graphical interface with a user to actuate the controller to provide an electrical output to the lighting array. The combination may be placed on a building, vehicle or any object to allow a plurality of lighting themes and palettes. Music may also be used to control the lighting output as well as speed or acceleration.

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 is equipped with sensors that 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 independently energize localized groups of lamps to provide enhanced lighting effects, while using significantly less wire material. Interactive remote control is 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.

Provided is a lighting system that includes a plurality of luminaires, at least one controller in communication with the luminaires via a communication line in a network, and configured to control the luminaires, and a lighting control system including a smart device which wirelessly communicates with the at least one controller and the plurality of the luminaires, and performs a commissioning operation of the luminaires in the network using visual light communication (VLC).

Securing device rejoining for a mesh network of a wireless lighting control system is disclosed. A potential security weakness of a mesh network protocol is that a proprietary link key may be discovered by close, expert examination of a device, potentially facilitating the joining of a rogue device to the network. Requiring subsequent rejoins of any device that had previously joined the network to use a current randomly generated link key, rather than the proprietary link key, prevents rogue devices only having the proprietary link key from joining.

A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.

Systems and methods for of dimming generally considered to be non-dimmable with conventional dimmers. An exemplary dimming module accepts a power source for a light source and a dimming signal. The dimming module modifies the power signal and generates a modified power signal capable of dimming LED light sources (and other light sources) that are generally considered to be non-dimmable with conventional dimmers. The dimming signal can be a wireless signal. Exemplary embodiments include a computer application executing on a computer or handheld computer that can be used to remotely dim, via the dimming module, one or more LED light sources (and other light sources) that are generally considered to be non-dimmable with conventional dimmers.
