International Classification:

F21V 29/00

US Classification:

362218

Abstract:

A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

US Classification:

36221705, 36221716, 36224902, 29825

Abstract:

Lighting retrofit systems and methods are disclosed that can be used with different light fixtures, but that are particularly adapted for use with retrofitting troffer-style fixtures with LED based light engines. The retrofit systems being assembled without disturbing the lighting or troffer pan or housing (“troffer pan”) for the lighting system being retrofitted. Some of these embodiments can comprise a mounting fixture or frame that can be mounted in an opening in a ceiling grid, and held in place between the grid and the troffer pan edge. The fixture or frame can comprise an opening for a light engine, with the engine being quickly and easily connected to electrical power in the troffer pan and then mountable within the frame opening. These embodiments can allow for the quick and easy construction of the retrofit system without the need for adhesives and fasteners such brackets and screws.

International Classification:

F21V 29/00
F21V 13/04
F21V 7/00

US Classification:

362218

Abstract:

A direct lighting fixture that is well-suited for use with solid state light sources, such as LEDs, and particularly useful for lighting aisles in commercial and industrial environments. An elongated housing comprises several integral elements including a heat sink, opposing side reflectors, and a mount surface. A plurality of light sources is disposed on the mount surface. Each light source or cluster of sources has an optical element such as a lens over it to redirect a portion of the light emitted from the sources in a desired direction, for example, to collimate the light. Reflective elements are placed on both sides of each light source or cluster to redirect light that is initially emitted in a longitudinal direction. The fixture may comprise multiple elongated housings connected together and aligned in parallel along the longitudinal direction. The fixture may also be scalable.
