FORMABLE THREE-DIMENSIONAL LIGHTING DEVICES
First Claim
1. A lighting device, comprising:
- a formed flexible substrate having a shape;
a stretchable conductive trace located on the formable flexible substrate; and
a plurality of solid state light sources attached to the stretchable conductive trace;
wherein the shape of the formed flexible substrate extends in three dimensions and comprises a three-dimensional structure, wherein a solid state light source in the plurality of solid state light sources is located so that light emitted therefrom is beam shaped by the three-dimensional structure.

Abstract
A formed lighting device having a shape that extends in three dimensions is provided. The formed lighting device includes a formed flexible substrate having a shape, and a stretchable conductive trace located on the formable flexible substrate. A plurality of solid state light sources are attached to the stretchable conductive trace. The shape of the substrate, and thus the lighting device, extends in three dimensions and includes a three-dimensional structure that beam shapes light emitted from one of the solid state light sources. The three-dimensional structure may be a plurality of peaks and a corresponding plurality of valleys. A set of solid state light sources in the plurality of solid state light sources may be located in the plurality of valleys.
