Technological Landscapes: The Revolution in Lighting
Lexington-based QD Vision, Inc., a nanotechnology company, is a leader in the use of quantum dots to dramatically improve lighting.
The United States Energy Information Administration (EIA) estimates that lighting in the United States represents about 25 percent of our total energy usage. As a result, considerable effort is underway in academia and industry to develop more efficient light sources to replace incandescent bulbs that are only 10 percent efficient in converting electrical current into light. The first lighting improvement in over one-hundred years is the curly-cue shaped compact fluorescent lamp (CFL) that is three times more efficient than the incandescent lamp. Still, most of its output energy is lost as heat. The invention of the blue light-emitting-diode (LED) is three times more efficient than the CFL but has serious color problems. Its color is …
