Abstract

A diffuse light reflector is disclosed for use in lighting fixtures including luminaires, light boxes, displays, signage, daylighting applications, and the like. The reflector includes a light reflective nonwoven and a polymer layer that enhances reflectivity. The reflector can be laminated to coil steel or aluminum and can be formed in metal coil or sheet forming operations. The polymer layer can be easily cleaned of machine oils from the metal forming operations.

Description

[0001] This application claims benefit to Provisional Application No. 61 / 210,674 filed Mar. 20, 2009, the entire contents of which are specifically incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention relates to a polymeric coated diffuse light reflector for use in light reflective articles such as lighting fixtures and the like in which diffuse light reflectance is desired.

[0004] 2. Description of Related Art

[0005] Reflectors are used in numerous types of lighting fixtures to maximize the usable light, thus increasing the lighting efficiency. Maximization is achieved through a combination of reflecting and redirecting light generated by the lamp in a desired direction, and minimizing the light absorbed by the reflector. This is particularly important when the light fixture design includes a light cavity in which light rays are redirected multiple times within the cavity before exiting the light fixture as usable light.
