Abstract
A lighting device formed of a FIPEL panel driven by electrical connection. For example, a frequency generator can create a frequency that creates a light output having any frequency in the spectrum. The light emitting panel can be flexible, and can be coded along a curved surface, such as the inner surface of a light bulb.
Claims24
A lighting device, comprising
- a housing, having at least one surface through which light is output;
- first and second electrical connections;
- a signal generator, driven by electricity on said first and second connections to output a signal having a frequency;
- said housing having a non-flat surface for holding a light emitting substance that receives the signal from the signal generator, and
- where said light emitting layer is flexible, and formed of multiple layers of materials, said multiple layers of materials excited by said signal generator to output light of a certain wavelength dependent on the said frequency emitted by said signal generator through said surface.

A method of creating light from a device, comprising
- connecting first and second electrical connections to a signal generator, to cause said signal generator to output a signal having a frequency;
- holding a light emitting substance formed of multiple stacked layers of material in a housing on a non-flat surface, and driving said light emitting substance with the signal from the signal generator to emit light.
A lighting device, comprising
- a housing,
- first and second electrical connections;
- said housing holding a light emitting layer driven by power from the first and second electrical connections;
- and
- where said light emitting layer is formed of a first stack, having multiple layers of materials between first and second electrodes, and a second stack, stacked on said first stack, and between said second electrode, and a third electrode, said first stack and said second stack emitting light separately,
- said light emitting layer emitting light through the housing.
