20110122603 | INTEGRATED LABORATORY LIGHT FIXTURE - The integrated laboratory light (lablight) fixture is a sealed ceiling mounted fixture that combines air outlets, lighting and other devices for use in laboratory, clean room, healthcare, educational, and other facilities requiring critical airflow control. The integrated lablight is made for a central location in the lab to eliminate room scale eddies and cross drafts along with the hood challenges they present. The combining of most ceiling devices in one fixture results in a safer environment with greater access for above ceiling maintenance, as well as less expensive facility capital costs. The fixture design also minimizes shadows at the work surface, and promotes temperature stability for temperature sensitive equipment. | 05-26-2011 |
20120044670 | METHODS AND APPARATUS FOR PROVIDING LIGHTING VIA A GRID SYSTEM OF A SUSPENDED CEILING - Methods and apparatus for providing sources of light, or mechanical and/or electrical connections for light sources, via a grid system of a suspended ceiling. All or a portion of a grid system for a suspended ceiling may be configured to support the generation of light. Lighting units may be coupled to various portions of the grid system in a removable and modular fashion, so as to be completely or substantially recessed above the ceiling surface, or as pendant components hanging below the ceiling surface. Lighting interface components of the grid system also may be configured to facilitate significant thermal dissipation from lighting units. In one exemplary implementation, one or more LED-based lighting units may be coupled to one or more lighting interface components of the grid system so as to provide controllable multi-color and/or essentially white light. | 02-23-2012 |

20090196024 | Ceiling-Mounted Troffer-Type Light Fixture - A ceiling-mounted troffer-type light fixture for illumination. The fixture comprises a body with a first flange having at least one hook-receiving opening and a second flange with a suspension-member-receiving opening. A cover includes a rectangular frame, at least one catch-arm and at least one suspension member. Frame fasteners along the frame engage the perimeter in a closed position. One-person attaching/closing and removal of the cover for maintenance is facilitated by the cover being supported in an open position, suspended position and fully engaged with the body in a closed position. | 08-06-2009 |

20130308303 | Lighting System for an Architectural Ceiling Structure - A lighting fixture forms at least a portion of a grid system for a suspended ceiling. The lighting fixture includes a runner having a substantially uniform, elongate, thin web coupled to a fixture base defining first and second flanges disposed on opposite sides of the web. The flanges support respective ceiling tiles. The base defines a fixture receptacle configured to receive a light source. A retainer may be supported by the fixture base to secure the light source in the fixture receptacle. | 11-21-2013 |
20160116136 | EDGE LIT FIXTURE - An edge lit fixture. A housing provides the basic shape and structure of the fixture. The housing is constructed from discrete segments including lens frames, side frames, and end frames, which can be used in many different combinations to create the desired fixture. The assembled housing defines an open central area. One or more light panels are arranged around the perimeter of the housing such that at least some of the light is emitted toward the central area. The open central area of the housing allows for existing materials, such as a ceiling tile, for example, to function as a back surface of the fixture. | 04-28-2016 |
