Recently, Vanderbilt University, a graduate student accidentally discovered in a single experiment, a hybrid " Paint "Painted LED After the lamp was originally a blue lantern like ordinary incandescent bulbs, as issued White . The invention uses a Epoxy resin . Scholars predict that a revolutionary new discovery is likely to be Illumination The concept of property extended to the light bulb, the only painted this "paint" any object can play the role of light bulbs.
Michael? Bowles is a graduate of Vanderbilt University, mixed "paint" the invention came from his accidental discovery in the experiment. In that experiment, the Powers had just trying to make really small quantum dots, size of several nanometers, less than one thousandth of a human hair. Quantum dots is Semiconductor Nano-crystalline materials can be referred to as semiconductor nanocrystals, also known as "artificial atoms", by the small number of atoms, a dimension of 100 nanometers or less. General quantum dots contain anywhere from 100 to 1,000 electronic, these electronic active and smaller quantum dots. Shine a light on quantum dots or apply electricity to them will be active after the quantum dots, given the various colors of bright light. But when Bowers shined a laser on his quantum dots, something unexpected happened. "When a white glow covered the table, I was surprised," Bowers said, "The quantum dots were supposed to Blu-ray, but they are giving off a beautiful white light."
Achieve that surprised to discover, the Bowers and another Student Germination of a new idea. China Epoxy Resin Industry Association Expert Explained that the dots they Polyurethane / Epoxy resin mixture, after mixing, the mixture will coat a blue LED lights on. Apply mixed "paint" the light bulb size "bloated." But the important thing is it really like, such as Bowers issued a white light. This white is not the blue light-emitting diode white light through the formation of the converted, but warmth like incandescent bulbs issued, yellowish white. LED and incandescent white hair is not the same principle. The former issue by injecting electric phototherapy, phototherapy must be converted by a phosphor, and then mixed by light to form white light. The latter is W Continuous Twisted white hot issue.
And with 60-watt than standard incandescent bulbs, painted "paint" the light bulb light about 2 times brighter than the former, lighting time is extended about 50 times. Quantum dots mixed "paint" the invention, by scientists that will enable the application of light-emitting diodes into a new era. Compared with the 60-watt standard incandescent lamp, the LED light brighter lighting for longer, can last 50,000 hours and not easy to break. LEDs do not heat therefore also more energy efficient. If all use LED lighting, to the 2025 U.S. energy consumption for lighting than they are now down 29%. Issued in 1998 before the advent of white LEDs, it can only produce red, green, yellow and blue color light, thus limiting the scope of use. Time limits for use in light-emitting diode traffic lights, flash and Building Lighting purposes, for general lighting in terms of white light that people need. The invention in 1998, white light LED white light can be issued through conversion, and therefore inefficient. Therefore, this discovery could greatly expand the application of light-emitting diodes. Scientists have even expressed the hope that eventually replace the incandescent light-emitting diodes, fluorescent lamps and sodium lamps.
In fact, if the invention can be commercial promotion, light bulbs will no longer be the only source of light. Quantum dots mixed "paint" can be spread on any one specific thing, as long as the issue of quantum dots of various colors can activate the light, including white light, light bulb then maybe on the end times.
