Flexible lighting device having unobtrusive conductive layers
First Claim
1. A method of forming a lighting element, comprising:
- forming a first substrate;
applying a first conductive element over the first substrate;
applying a second conductive element over the first substrate;
installing a light-emitting element over the first substrate such that a first contact of the light-emitting element is electrically connected to the first conductive element and such that a second contact of the light-emitting element is electrically connected to the second conductive element, the first and second contacts both being on a first surface of the light-emitting element;
forming a first transparent conductive layer at least partially adjacent to the first contact and at least partially adjacent to the first conductive element, the first transparent conductive layer being configured to electrically connect the first contact and the first conductive element,forming an affixing layer over the first substrate; and
forming a transparent layer over the light-emitting element and the affixing layer such that the affixing layer affixes the transparent layer to the first substrate,whereinthe first transparent conductive layer, the transparent layer, and the affixing layer are all sufficiently transparent to visible light such that they will not decrease light transmittance below 70%,the light-emitting element is configured to emit light having a first narrow range of wavelengths between 10 nm and 100,000 nm from the second surface; and
the first and second conductive elements are both at least partially transparent to visible light.

Abstract
A flexible lighting element is provided, comprising: a first substrate; first and second conductive elements over the first substrate; a light-emitting element having first and second contacts that are both on a first surface of the light-emitting element, the first and second contacts being electrically connected to the first and second conductive elements, respectively, and the light-emitting element emitting light from a second surface opposite the first surface; a transparent layer located adjacent to the second surface; and a transparent affixing layer located between the first substrate and the transparent layer, wherein the transparent layer and the transparent affixing layer are both sufficiently transparent to visible light that they will not decrease light transmittance below 70%, and the first and second conductive layers are at least partially transparent to visible light, or are 300 μm or smaller in width, or are concealed by a design feature from a viewing direction.
