Appl. No.:

10/461850

Inventors:

Walter Blue Clark - Palo Alto CA, US
David Daoud Aziz - Newark CA, US

Assignee:

Finelite, Inc. - Union City CA

International Classification:

F21S 8/06

US Classification:

362408, 362147, 362299, 362308, 362328

Abstract:

A lighting system and device for providing indirect light using free-cavity, double-diffusing configurations are disclosed. In accordance with the embodiments of the invention, a lighting fixture comprises a cover structure with a diffusion layer and a reflective plate that form the free-cavity. The free-cavity is preferably configured to provide an output of light from a light source positioned within the free-cavity with an efficiency rating of 70% or more and provide better than an 8:1 ceiling lighting contrast between the rows of fixtures with rows on 16 feet spacing. Further, in accordance with a preferred embodiment of the invention, a device is configured to couple to a ceiling structure and provide the indirect lighting from a fluorescent light source.

Abstract:

A system and architecture for managing lighting through a seamless low-voltage bus network is disclosed. The system comprises a plurality of control units that serve as nodes for integrating devices, such as light fixtures, control switches and sensors into the bus. Each of the control units preferably includes a printed circuit board and node interconnects for assembling the low-voltage bus and for integrating the devices. Alternatively, the system comprises a central hub with a master printed circuit control board and a plurality of interconnects for assembling the bus and for integrating the devices.

Abstract:

A T-bar clip assembly that securely couples to T-bar structures that are used to construct suspended ceiling is disclosed. The T-bar assembly is configured to support one or more electrical fixtures and provide power feeds to the one or more electrical fixtures. The T-bar clip assembly comprises support brackets that secure to the T-bar structures and one or more housing structures that attach to a portion of the support brackets to form one or more corresponding junction box enclosures. The junction box enclosures provide the power feeds to the one or more electrical fixtures at locations that are substantially flush with support flanges of the T-bar structure, an outer surface of the removable ceiling tiles or both.

Abstract:

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.
