Abstract
A flexible organic light emitting diode (OLED) fiber light source is provided. The OLED contains a fiber core, a cathode, at least one organic radiation emitting layer and a transparent anode. The fiber light source may be used as a flexible novelty lighting article or coiled inside a large area lighting source.
Claims24
A fiber organic radiation emitting device comprising:
- a fiber core having an outer first electrode;
- at least one organic radiation emitting layer positioned over an outer surface of the first electrode;
- and
- a radiation transmissive second electrode positioned over the organic radiation emitting layer;
- wherein the at least one organic radiation emitting layer comprises an organic material that emits the radiation when a voltage is applied across the first and second electrodes.
2 more elements
A flexible, fiber organic radiation emitting device, comprising:
- a flexible elongated core member having an outer surface;
- a cathode having an inner surface surrounding the outer surface of the core member;
- at least one non-planar organic radiation emitting layer, having an inner surface surrounding and contacting an outer surface of the cathode;
- a radiation transmissive anode having an inner surface surrounding and contacting an outer surface of the at least one organic radiation emitting layer;
- a metal contact element having a first surface in contact with a first portion of an outer surface of the anode;
- and
- a power source electrically connected to the cathode and the metal contact element.
4 more elements
