Organic LEDs or OLEDs are looking like a promising way of making cheaper and longer-lasting light sources, reducing power consumption in the process. At least one group of researchers has created a bulb driven by nanotubes. Tiny electron emitters, called field emission devices, including ones based on nanotubes, hold promise for use in flat panel displays.
Significant Changes in Lighting Technologies
Significant changes in lighting technologies are expected in the next ten years. Semiconductors used in the preparation of light emitting diodes (LEDs) for lighting can increasingly be sculpted on nanoscale dimensions. In the United States, roughly 20% of all electricity is consumed for lighting, including both incandescent and fluorescent lights.
Projected Savings Through Nanotechnology
In 10 to 15 years, projections indicate that such nanotechnology based lighting advances have the potential to reduce worldwide consumption of energy by more than 10%, reflecting a savings of $100bn dollars per year and a corresponding reduction of 200 million tons of carbon emissions (NNI: The Initiative and Its Implementation Plan).
Future Applications of Nanotechnology in Lighting
Future Applications of Nanotechnology in Lighting could see nanotubes being used for more efficient and powerful electron emission. It is expected this would make lights last a lot longer and also use less electricity.
