有望な idea: 最高の-efficient light outshines low-energy bulbs

Last updated at 21:09 28 December 2007


A new 世代 of 最高の-efficient light bulbs was 明かすd by scientists yesterday.

They said the bulbs would （一定の）期間 the end of 正規の／正選手 filament models within three years.

雇うing Light Emitting Diode 科学（工学）技術, the bulbs would use いっそう少なく electricity than the lowenergy 見解／翻訳／版s that families are 現在／一般に 存在 勧めるd to 投資する in.

LED lights, which are used in 電気の gadgets such as 動きやすい phones and computers, have been 裁判官d unsuitable to light homes until now because they are not 有望な enough to illuminate whole rooms.

But 研究員s believe they have 設立する a way of making the 装置s much brighter without using any more 力／強力にする.

Faiz Rahman, who is 主要な the 事業／計画（する） at the University of Glasgow, said: "By making microscopic 穴を開けるs on the surface of the LEDs it is possible to 抽出する more light, thus 増加するing the brightness of the lights without 増加するing the energy 消費.

"As yet, LEDs have not been introduced as the 基準 lighting in homes because the 過程 of making the 穴を開けるs is very time-消費するing and expensive.

"However, we believe we have 設立する a way of imprinting the 穴を開けるs into billions of LEDs at a far greater 速度(を上げる） but at a much lower cost."

The 研究 team has been using a technique called nano-imprint lithography to etch microscopicholes on to the LEDs, 許すing more of their light to escape.

The 事業／計画（する） is 存在 developed in 合同 with the 学校／設ける of Photonics and the University of Strathclyde in Glasgow.

"LEDs not only use いっそう少なく 力／強力にする than 現在の energy efficient light bulbs but they are much smaller and can last years without needing to be 取って代わるd," 追加するd Dr Rahman.

"This means the days of the humble light bulb could soon be over."

The 研究員s made use of nano 科学（工学）技術 --precision 工学 of 実体s at molecular and 原子の level. The techniques are ますます 存在 used in 着せる／賦与するing, electronics and 製造業の 同様に as in health and cosmetics.
