Concentration is the essence? A bulb smaller than a coin can live for 60 years

In 2009, the University of Cambridge researchers have developed a low price led bulb, it uses less power will be able to produce a bright light bulb, such as the price of each 2 pounds, 60 years of sustainable use.

Although it is smaller than the coin, but it is 12 times the traditional tungsten bulb lighting effect, while it is the current fluorescent energy-saving lamp lighting effect of 3 times.

Unlike the current energy saving bulbs, this new type of bulb can instantly illuminate. It is reported that this light-emitting diode bulbs can reduce household lighting bills 3/4. If you install a new bulb in your home and office, you can reduce the amount of electricity consumed in the UK from 20% of total electricity consumption to about $5% a year.

This new type of light-emitting diode light bulb for 100 thousand hours, is the current energy saving bulbs lit time of 10 times. It does not contain mercury, so cleaning does not cause environmental pollution. In addition, it does not appear when the lights flashing.

The British government said that the change from the traditional light bulbs to become energy-saving bulbs will reduce carbon dioxide emissions by 5 million tons per year, if the use of this new LED bulbs will be more effective in reducing carbon dioxide emissions.

Before this led bulb high manufacturing cost, is mainly used for sapphire wafer as a raw material, however, scientists from the University of Cambridge center of gallium nitride solutions using silicon wafer as raw materials.
