Bulbs have been the target of environmentalists and the producers of eco-friendly products for quite some time now. Here is a fresh attempt from researchers at Glasgow University, Scotland. Light Emitting Diodes (LEDs) produced by them are believed to be many times more energy-sufficient, apart f om being more durable, and a perfect substitute for regular bulbs in three years. In this endeavor, they have the continual support of the Institute of Photonics, Strathclyde University, Mesophotonics, and Sharp Laboratories of Europe, as part of the BERR Technology Programme.
The researchers have come up with a new mechanism to make the LEDs more useful. Dr Faiz Rahman explains how. By making microscopic holes on the surface of the LEDs it is possible to extract more light, thus increasing the brightness of the lights without increasing the energy consumption. The team of researchers use a technique called nano-imprint lithography to directly imprint the tiny holes onto the LEDs allowing more of the light to escape.
The researchers also hope to bring down the cost of installing these bulbs, which, in turn, would increase their popularity manifold as domestic light sources. Also, the researchers are working on reducing the problem involved with these bulbs-their material and structure traps light and reduces brightness.
