Abstract
A luminaire a small number of carefully designed extrusions is easily manufactured. The housing is formed by joining four pieces having a first extrusion profile. A second extrusion profile is used for the side and end covers. A third profile is used for access covers. The housing frames a lens, such as an acrylic sheet, and long lines of LEDs are positioned to shine directly into the side of the lens. A reflective layer on the lens directs all or some of the LED light out the luminaire'"'"'s front, perhaps directing some light out the back. Strategically positioned diffusors ensure a pleasing lighting effect. The result is a very thin and light weight luminaire having a large surface area. The luminaire can be suspended by threaded nipples, by cables threaded through holes in the back, or by brackets screwed to threaded inserts.
