Researchers at Scotland's Glasgow University say they have found a way to make LEDs brighter without making them less energy efficient. The Glasgow researchers are using a process known as "nano-imprint lithography" to make microscopic holes on the surface of LEDs to increase the level of light they radiate. Previously, the process of making holes in LEDs had proved both time consuming and expensive. However, Fraiz Rahman, the projects leader, said his research team has discovered a way to imprint holes in "millions of LEDs at a far greater speed and a much lower cost than ever before." Quickly adding: "This means the days of the humble light bulb could soon be over." Rahman was working in partnership with the Institute of Photonics at Scotland's University of Strathclyde, Mesophotonics Ltd in the UK, and Sharp Labs of Europe to bring the concept to market.
