Super-Efficient Light Bulb
Thursday, January 3, 2008 by PPV
A new type of super-efficient household light bulb is being developed which is brighter and uses less power than energy efficient light bulbs currently on the market.
Light Emitting Diodes (LEDs) are used in gadgets like cellphones and computers previously are not powerful enough compared to regular bulbs used for lighting.
But Glasgow University scientists said they had resolved the problem by making microscopic holes in the surface of LEDs to increase the level of light they give off.
The process is known as nano-imprint lithography and as of now is time consuming and very expensive. But this means the days of the humble light-bulb could soon be over.
