Scientists report breakthrough efficiency and brightness leds




Researchers at Princeton University have developed a method that claims to be the brightness and efficiency of LEDs improves significantly. The innovation could reduce costs. LEDs in time

LEDs are seen as efficient and compact light sources. Researchers from Princeton places however there caveats. Regular LEDs were only two to four percent of the light produced is actually emit. The vast majority of the light is, according to the researchers within the LED is reflected by the structure of the diode. The lifetime of an LED would thus shortened, because more heat. Researchers have made several attempts to remedy this problem, but all techniques would reduce. Ultimate light quality

The researchers have developed nanotechnology PlaCSH, which is suitable for LEDs of organic materials. Nanotechnology is also useful for LEDs based on inorganic materials. The renewed minute and metallic structure of the design would be able to be better to the outside for guiding the light. The authors claim that LEDs emit, on the basis of this technique up to 60 percent of the light produced. There also release more heat, which largely resolves the heat problem. The brightness of the LEDs could improve. PlaCSH the technology up to 400 percent

PlaCSH LEDs of Princeton University

Project leader Stephen Chou A few years ago a similar design used for solar cells. His technique was able to get 96 percent of sunlight into electricity and thereby be. 175 percent more efficient
