New efficient bulb sees the light

Perhaps the days of currently used "humble light-bulb" will go the ways of dodo. Glasgow University scientists along with scientists from the Institute of Photonics at the University of Strathclyde, found a cheaper and efficient way of "making microscopic holes in the surface of LEDs to increase the level of light they give off.

This is a process known as nano-imprint lithography.

Dr Faiz Rahman, who is leading the project, said: "As yet, LEDs have not been introduced as the standard lighting in homes because the process of making the holes is very time consuming and expensive.

"However, we believe we have found a way of imprinting the holes into billions of LEDs at a far greater speed, but at a much lower cost."
