US 2013/0279159 A1 · DIRECT AISLE LIGHTER

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.
