20160120001 | Color temperature tuning - An advance control LED lighting system is disclosed. The lightings system includes LED light fixtures with sets of different white LED arrays that emit different output spectra. The system includes a control unit for adjusting relative intensities of light outputs from the different sets of white LED arrays as well as the combined intensity of light output from the different sets of white LED arrays to produce ranges combined output light intensities and the combined output light color temperatures. Preferably the control unit includes a wireless transmitter for receiving and processing input control signals from a remote control interface device, such as a smart-phone or computer. The system also includes sensors coupled to the control unit for automatically adjusting one or more of the combined output light intensity and the combined output light color temperature based on a measured or detected condition. | 04-28-2016 |
20150070883 | Light Emitting Diode Luminaire Device and System - A lighting device is disclosed that includes one or more master circuit boards configured to power light emitting diodes. The lighting device also includes modular light boards with arrays of light emitting diodes that interchangeably couple to the matched connectors on the master circuit board. The master circuit boards and the modular light boards are positioned within a housing with one or more diffuser lenses. In accordance with the embodiments of the invention, master circuit boards and modular light boards are mounted in a stacked arrangement to emit light from opposed sides of the housing. In further embodiments of the invention, the lighting device includes a controller for independently controlling light output from each master circuit board. | 03-12-2015 |
20150049479 | Lighting system with angled LED arrays - A lighting system with extended arrays of LED light engines is disclosed. The extended arrays of LED light engines are coupled to bent, curved, contoured or angled support surfaces withing a housing structure, coupled to bent, curved, contoured or angled surfaces of the housing structure or a combination thereof. Preferably, the extended arrays of LED light engines emit both upward and downward lighting through diffuse surfaces of the housing structure. In some embodiments of the invention the positions and/or angles of light emitting surfaces of extended arrays of LED light engines are adjustable within the housing structure. | 02-19-2015 |
20150048751 | Bi-level dimming controller for led light fixture - A bi-level dimming control circuit is disclosed. The bi-level dimming control circuit is electrically coupled between two switches and a driver circuit that is compatible with 0 to 10 volt dimming signals. The bi-level dimming control circuit controls the output from the driver circuit based on the on and off positions of the switches. In repose to the on and off positions of the switches the driver circuit powers a light engine between a maximum light output mode, a zero light output mode and a reduced or dimmed light output mode. The bi-level control circuit is used to modulate LED light engines, fluorescent light engines and combinations thereof. | 02-19-2015 |
20140232267 | Workspace lighting system - A modular lighting system for lighting a work area is disclosed. The system includes a power supply with power outlets for powering LED fixtures. The power supply preferably operates at or below a fixed power output level, such as to illuminate the work area using less than 0.2 Watts per square foot of energy. The lighting system also includes an occupancy sensor and/or a light level sensor for controlling lighting levels in the work area in response to detection of a person, ambient light levels and/or a combination thereof. The lighting system can also include computer unit with a micro-processor and a memory unit for running software or firmware the executes lighting programs, stores light usage histories and/or provides system reports to a remote computer by a wireless means and/or over a computer network. | 08-21-2014 |
20140063776 | LED lighting system - A lighting system includes a low-profile LED driver box with quick connect LED drivers that are accessible through service doors, panels or plates. The LED driver box attaches to a ceiling mount to support or suspend an LED light fixture. The LED light fixture is suspended from the LED driver box through a power-feed suspension mechanism that includes at least one direct current power conductor cable to power to the LED light fixture. The LED light fixture includes one or more linear arrays of LEDs. The system also includes a controller or dimming circuit for controlling light output and/or a backup battery for providing power to the LED light fixture in the event of a power failure. | 03-06-2014 |
