The days of the humble light-bulb could soon be over

London, Dec 29 (ANI): Researchers are developing a new generation of super-efficient household light bulbs, which could herald the end of traditional bulbs.

Light Emitting Diodes (LEDs), used in gadgets such as mobile phones and computers, had been unsuitable for household use until now because they are not bright enough to light whole rooms.

However, experts believe that they have now found a way of introducing LEDs into households that are brighter, and use even less power than currently available energy efficient light bulbs.

Scientists at Glasgow University, who are developing the project in partnership with Institute of Photonics at the University of Strathclyde, are using a process known as nano-imprint lithography, which involves making microscopic holes in the surface of LEDs to increase the level of light they give off.

“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, BBC quoted Dr Faiz Rahman, who is leading the project, as saying.

“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.

“This means the days of the humble light-bulb could soon be over,” he added. (ANI)
