A method (3600) and system (2800, 2900, 3000, 3100) autonomously create a restore point for a luminaire controller (2810, 3110) and restore it to proper operation when required. The luminaire controller operates by using first operating software having a first software image, and receives a second software image of second operating software. The luminaire controller communicates the first software image to a first device (2820, 3120) connected to the luminaire controller via a communication network (2805, 3105), installs the second operating software, and performs a self test of the luminaire controller. If the luminaire controller fails the self test, the luminaire controller requests via the network that the first device transfer the first software image to the luminaire controller via the network, receives the first software image, installs the first operating software, and reverts to operation with the first operating software.

A handheld device for merging groups of lighting fixtures is disclosed. The handheld device includes a communication interface configured to wirelessly communicate with a plurality of lighting fixtures and control circuitry. In one embodiment, the control circuitry is configured to effect selection of a first lighting fixture or a first switch module that is grouped with a first group of lighting fixtures via the communication interface; identify the first group of lighting fixtures; effect selection of a device-to-be-added that is not initially associated with the first group of lighting fixtures via the communication interface; determine a new group by adding the device-to-be-added to the first group of lighting fixtures; create group assignment information for the new group; and send the group assignment information to each of the first group of lighting fixtures and the device-to-be-added of the new group via the communication interface.

A handheld device having a communication interface configured to wirelessly communicate with a plurality of lighting fixtures and control circuitry is described. In one embodiment, the circuitry is configured to effect selection of a first lighting fixture in a first group of lighting fixtures via the communication interface; identify the first group of lighting fixtures based on information from the first lighting fixture; determine new settings for the first group of lighting fixtures; and send the new settings to each of the first group of lighting fixtures via the communication interface, wherein the first group of lighting fixtures includes a defined plurality of lighting fixtures that are associated to operate in a coordinated manner.

A lighting fixture having a light source, a light sensor, a communication interface, and circuitry is described. In addition to controlling the light source, the circuitry is adapted to monitor for a light signal provided from a handheld device via the light sensor; upon receiving the light signal, measure a signal level associated with the light signal; and effect transmission of the signal level to the handheld device via the communication interface. In one embodiment, the circuitry is further configured to receive an instruction to monitor for the light signal from the handheld device via the communication interface such that the circuitry begins monitoring for the light signal upon receiving the instruction.

This ID describes a technique for a Power over Ethernet PD (Powered Device) to discover the port injection voltage the PSE (Power Providing Equipment) is using. This is required to determine the maximum current the PD will be able to draw without being cut off by the PSE. This in turn is used to extract the maximum possible power from the PSE.

The present invention relates in general to the provision of system, method and apparatus for providing temporary low voltage power and is useful for providing power for a Power-over-Ethernet (PoE) powered lighting network. The present invention is useful in a building under construction. Advantageously, the inventive technology includes mobile apparatus that is transportable, thus allowing the apparatus to be transported onto a site, used, and transported from a site. Furthermore, the inventive technology beneficially includes equipment for providing conditioned air space within the apparatus.

A handheld device having a light source, a communication interface, and control circuitry that is capable of interacting with a lighting fixture. The handheld device is capable of providing a light signal to the lighting fixture, receiving information from the lighting fixture, and selecting the lighting fixture as a selected lighting fixture based on the received information.

Techniques presented herein are directed to the coordinated network-based control of the color capabilities of multi-color fixtures. A network device is connected to multi-color light fixtures each comprising a local processor and a plurality of color light emitters. The network device receives data inputs from one or more data sources and uses the data inputs to identify a color informational display for presentation across a plurality of the multi-color light fixtures. The network device generates messages encoding light control settings for each of the plurality of multi-color light fixtures enabling each multi-color light fixture to present a spatial or temporal segment of the color informational display and sends the messages to the plurality of light fixtures. Execution of instructions embedded in the messages by the local processors results in the creation of the color informational display across the plurality of multi-color light fixtures.

An improved LED lighting system is provided for overhead ceiling lighting, as well as for other uses. The LED lighting system comprises elongated linear lamps having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The linear LED lamps have associated modular network connectors and control components so that they can receive control data and power signals over a single network cable according to a standardized power and data network communications architecture such as Ethernet. The system includes connector assemblies designed to securely mount the networkable linear LED lamps to conventional tube lamp lighting fixtures or to another support housing and to provide integrated power and data connectivity to internal components of the lamps. In one form, the disclosed system includes a network enabled snap-fit connector assembly mounted to a lighting fixture and configured to provide Ethernet power and data connectivity to the lamp. The LED lamps have first and second mechanical connectors at opposite ends of the lamp body, and the snap-fit connectors are configured to secure the lamps to an overhead lighting fixture or other support structure as an incident of the lamp ends moving relative to the mounting connectors in a substantially straight path that is transverse to the length of the body into an engaged position. The snap-fit connectors are also configured to form a network connection with an internal modular network connector associated with the lamp with the lamp mounted in its operative state on a support. In another form, a clipping mechanism is provided for mounting linear networkable LED lamps to an overhead grid ceiling system.
