The second generation light-emitting diodes: farewell the traditional household light bulb

Glasgow University researchers who are developing a new technology will replace the household light bulbs within three years.
LEDs have been used in a variety of electrical equipment such as computers and mobile phones. LEDs more energy-efficient than standard bulbs. However, due to structural and material constraints, many of the standard diode light is blocked, it will weaken the brightness does not apply to household lighting.
 
Currently, the researchers have developed a new generation of light-emitting diode, this diode than the standard energy-saving bulbs home brighter and more energy efficient.
Responsible for the research project at Glasgow University, Dr Faiz Rahman said: "The surface of the diode to drill a small hole can emit more light, so to keep energy consumption to increase without changing the light's brightness. So far, not as a standard light-emitting diode lighting device is fully introduced into the family, because the production process more time-consuming hole. However, the University of Glasgow through the use of world-class equipment, we firmly believe that we can find billions of holes and on the diode fast and cost-saving method. "
