Abstract
Flexible LED assemblies (300) are described. More particularly, flexible LED (320) assemblies having flexible substrates (302) with conductive features (304, 306) positioned on or in the substrate, and layers of ceramic (310) positioned over exposed portions of the substrate to protect against UV degradation, as well as methods of making such assembles, are described.
Claims18
A flexible LED assembly comprising:
- a flexible polymer substrate;
- a first conductive feature positioned within and on a surface of the flexible substrate;
- a second conductive feature positioned within and on the surface of the flexible substrate at a distance from the first conductive feature, such that a portion of the flexible polymer substrate between the first and second conductive features is exposed;
- and
- a ceramic layer positioned on the exposed flexible polymer surface between the first and second conductive features.
