Recently, a graduate of Vanderbilt University in the United States in an experiment accidentally discovered a mixture of "paint", led high bay lantern painted the original blue light-emitting diode lamp as white light like ordinary incandescent bulbs. led reef tank lighting. This invention used in epoxy resin. Academics predict that this new discovery is likely to revolutionize the concept of lighting objects extended to the light bulb outside, as long as this "coating" is painted, any kind of objects can play the role of the light bulb.
Michael Powers is a graduate of Vanderbilt University, led reef tank lighting, and mixed the "paint" the invention from his accidentally discovered in the experiment. In that experiment, Bowles was originally just wanted to create a very small volume of quantum dots, the size of a few nanometers, less than one thousandth of a hair. Quantum dots are nanocrystals made from semiconductor materials, can be called semiconductor nanocrystals, also known as "artificial atoms", led reef tank lighting, composed by a small amount of atomic size is generally below 100 nm.Ordinary quantum dots which typically contain 100 to 1000 electrons, these electrons are very active and the smaller the quantum dot. Quantum dots will power through quantum dots exposed to light or to give them active, issued by the bright light of various colors.But when Bowers shined a laser on the quantum dots, led reef tank lighting, something unexpected happened."When a bunch of white light enveloped the table, I was not surprised up," Powers recalls, "The quantum dots should be of blue, but they are now giving off a beautiful white."
Made the unexpected discovery, Bowers and another student sprout a new idea.China Epoxy Resin Industry Association, experts say, their mixture of quantum dots with polyurethane / epoxy resin mixture, the mixture is coated on a fat blue light-emitting diode lights. Coated with a mixed "paint" the light bulb size "bloated." But importantly, led reef tank lighting, it is true, as the Powers wish to issue a white. This white light is not light-emitting diode blue light through the formation of white light after the conversion, but like the warmth of incandescent light bulbs give a yellowish white. Light-emitting diodes and incandescent white light is not the same principle. Former through the injection power to issue the IPL,led reef tank lighting. IPL must be through some kind of phosphor conversion, and then mixed by light to form white light. The latter is a white light tungsten heating.
