Abstract: A direct and back view LED lighting system is disclosed. Embodiments of a lighting system and example light fixture are described. LED devices provide the light source. The LED devices can be positioned with a heatsink at or near the top of the system proximate to a back reflector. In example embodiments, the LED devices emit light downward. The system can be used in a troffer style fixture with a support structure and a pan. The system or fixture can have a lens arrangement including lenses, lens plates or sections with differing optical characteristics, including a partially reflective lens plate or section that passes and diffuses some light from the LED light source, but reflects some light back to the back reflector. Additional lenses or lens plates serve as diffusers.

Abstract: Troffer-style lighting fixtures are disclosed having troffer housing with reflective regions, and respective light emitting diode (LED) arrays mounted in the reflective regions. The LED arrays are arranged to emit out of said troffer housing to illuminate a room below. The LED arrays can be driven by an elevated drive signal to produce a high luminous flux. The light fixtures according to the present invention can have lenses and diffusers over the arrays arranged to mix and disperse light from the light source to reduce hot spots and the appearance of individual LED colors. A plurality of first diffusers is included, each over a respective LED array. A second diffuser is included over the first diffusers, with the LED light passing through the diffusers prior to emitting from the lighting fixture. The diffusers can have shapes, surfaces or materials to disperse and/or mix the LED light as it emits.

Abstract: A troffer-style fixture. The fixture is particularly well-suited for use with solid state light sources. The troffer comprises a light engine unit surrounded by a reflective pan. An elongated heat sink comprises a mount surface for light sources. An elongated lens is mounted on or above the heat sink. The mount surface is designed to accommodate the light emitters which may come on prefabricated a light strip. One or more reflectors extend out away from the heat sink on the mount surface side. A lens plate is mounted to proximate to the heat sink and extends out to the edge of the reflector(s). An interior cavity is at least partially defined by the reflector(s), the lens plates, and the heat sink. One or more light sources disposed along the heat sink mount surface emit light into the interior cavity where it can be mixed and/or shaped before it is emitted.

Abstract: A specular reflector and LED lamps using embodiments of the reflector are disclosed. Embodiments of the invention provide a reflector for solid state lamps. The reflector can be a specular reflector. The reflector includes a rigid, polymeric substrate and sputtered metal applied to the substrate. In some embodiments, the metal is silver. In some embodiments, the metal is applied without an intervening base coat. In some embodiments, the substrate is made from or includes an aromatic polyester such as polyarylate. The reflector can include a discontinuous or irregular surface yet still exhibit very high overall reflectivity and efficiency because the metal can be applied without an intervening base coat. In some embodiments, the reflector is used in lamps having a retroreflective optical design.

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.
