Shelf Lighting Device And Method
First Claim
1. A lighting device comprising:
- an elongated extrusion comprising a first surface and a second surface proximate said first surface, wherein said second surface is substantially reflective; and
one or more light emitting devices mounted at said first surface of said extrusion;
wherein said first surface is angled with respect to said second surface such that at least a portion of said light emitted from said one or more light emitting devices reflects off said second surface.

Abstract
The present invention provides various embodiments for apparatuses, systems, and methods for lighting devices used in shelving, displays, and the like. Some embodiments provide lighting device comprising elongated extrusions with a first surface and a second surface proximate the first surface. The second surface may be reflective. One or more light emitting devices may be mounted at the first surface of the extrusion. The first surface is angled with respect to the second surface such that at least a portion of the light emitted from the light emitting devices reaches the second surface. If the second surface is reflective, at least a portion of the emitted light will be reflected from the second surface. A protective and possibly light diffusive lens may be provided between the first and second surfaces. In other embodiments, lighting systems may be provided with a plurality of lighting devices as described above. One or more power transfer devices may be provided to connect the lighting devices in vertical and/or horizontal arrangements, and at least one power supply may be provided to power the power transfer devices and lighting devices. Additionally, dimmer devices with integrated sensors may be included to dim the lighting devices when reduced illumination is desired.
