摘要:
A light fixture includes a fixture body, a support structure, a plurality of light emitting diodes (LEDs) a driver, a cover, and a connector. The fixture body includes a first raceway, a second raceway, and a channel. The second raceway is substantially parallel to the first raceway. The channel is coupled to the first raceway and the second raceway such that the channel is substantially orthogonal to the first raceway and the second raceway. The support structure is coupled to the first raceway and the second raceway. The plurality of LEDs is coupled to the support structure and spaced apart along a length of the support structure between the first raceway and the second raceway. The driver is positioned within the channel and electrically coupled to the plurality of LEDs. The cover is detachably coupled to the channel and extends from the first raceway to the second raceway.

A system for controlling lighting includes a control module coupled to a driver, a light source coupled to the driver, a first sensor configured to cooperate with the control module to detect occupancy and control the power delivered to the light source according to a signal provided by the first sensor, and a second sensor configured to cooperate with the control module to detect ambient light and control the power delivered according to a signal provided by the second sensor. A GUI executing on a controller device wirelessly coupled to the control module communicates with the control module to configure the operation thereof, executes on a touch-sensitive display configured to facilitate user interaction with the controller, and creates one or more control groups. The GUI is also operable to control the driver to control the state of the light source. The control module is programmable to cause the driver to control the light source according to the detection by the first sensor of occupancy, turning it on upon detecting that an area is occupied and turning it off after a configurable delay period. The control module is programmable to cause the driver to control the light source according to the detection by the second sensor of ambient light. The system is configurable to include a switch to cause the light source to be turned on without regard to occupancy detected by the first sensor or ambient light detected by the second sensor.

A controller for controlling a plurality of lighting devices configured for wireless communications in a facility includes a data communications interface communicating with at least one of the devices. The controller further includes a control module configured to provide a control signal to the data communications interface for communicating to a transceiver associated with the device and for turning off the device according to an algorithm wherein the control signal is provided based on a time of day and/or a sensed condition relating to use of the facility. The transceiver reports device data to the control module to quantify a reduction in power obtained by controlling the devices according to the algorithm.

One embodiment of the invention relates to a system for operating a plurality of streetlights in response to motion from a vehicle. The system includes a sensor associated with at least one of the streetlights and configured to detect the presence of a moving vehicle and to provide a signal representative of the moving vehicle. The system further includes a radio frequency transceiver associated with each of the streetlights. The system yet further includes processing electronics configured to receive the signal representative of the moving vehicle from the sensor and to cause the radio frequency transceiver to transmit a command to one or more of the plurality of the streetlights to change lighting states along a pathway for the vehicle.

A lighting system for displacing energy is provided. The lighting system includes a light sensor to measure an amount of light provided from the natural lighting fixture to a building environment. The lighting system further includes processing electronics to receive information from the light sensor and to use the received information to determine when the amount of light provided from the natural lighting fixture is sufficient to allow one or more electric lighting fixtures to be turned off or dimmed, the processing electronics causing the one or more electric lighting fixtures to turn off or dim in response to the determination. The processing electronics are further configured to calculate the energy saved from turning off or dimming the one or more lighting fixtures. The lighting system further includes a communications interface configured to transmit the results of the calculation of energy saved from the processing electronics to a second party.

A method includes obtaining, at a metering device, power usage information associated with operation of a second technology; calculating, at a processor and based on the power usage information obtained from the metering device, a power base load capacity relief of an electrical system to a utility provider resulting from change from a first technology to the second technology; receiving, at the processor, a technology cost including fixed and variable costs to install and maintain the second technology; calculating, at the processor, a return needed for repayment of the technology cost; determining, by the processor, a new utility rate by apportioning the return needed for repayment of the technology cost as a function of the power base load capacity relief and calculating; and providing a utility invoice to the utility consumer for a power reduction over time at the new utility rate.
摘要:
A lighting device includes a substantially cylindrical tube defining an interior and an exterior, and a longitudinal axis extending between a first end and a second end. The first end of the tube defines a substantially cylindrical opening disposed in a plane at a first angle that is substantially perpendicular to the longitudinal axis, and the second end of the tube defines a substantially elliptical opening disposed in a plane at a second angle that is substantially non-perpendicular to the longitudinal axis. A reflective surface is provided on the interior of the tube, and a substantially cylindrical flashing is provided about the exterior of the tube. A substantially transparent dome is coupled to the tube proximate the first end, and a diffuser is coupled to the tube proximate the second end.
