UK manufacturing new silicon-based LED bulbs for 60 years

According to the British Daily Mail reported that a revolution in lighting is quietly carried out, the traditional bulbs and energy-saving bulbs will be fierce competition. At present, researchers at the University of Cambridge in the United Kingdom have developed a cheap light emitting diode (LED) lamp, which can reduce the amount of electricity can be released bright light. Its price is only 2 pounds, sustainable use of the past 60 years.

British scientists developed the latest light-emitting diode

Although the LED bulb is small than a penny, but its lighting efficiency is 12 times than traditional incandescent light bulbs, fluorescent lamp is 3 times of the low energy consumption. It is different from the current energy saving bulbs, the power supply can be directly illuminated. British Engineering and Physical Sciences Research Council believes that the use of new LED bulbs will reduce household lighting power consumption by 3/4. If the bulbs are installed in each home and office, the annual lighting consumption will be reduced to 20% of the total electricity consumption by up to 5%.

LED lighting can be lit for 100 thousand hours, than the modern energy-saving lamp with long service life 10 times, LED lamp does not contain mercury, so the waste treatment is rarely the destruction of the natural environment, at the same time, this new type of lamp does not appear flashing lights, flashing lights will make it because of migraine and epilepsy patients feel unwell.

At the beginning of January this year, the British "Daily Mail" reported that, people began to pay attention to the use of energy-saving light bulbs, many shops to stop a 100 watt incandescent bulb traditional inventory. This caused many consumers panic buying. The British government said that the use of energy-saving bulbs can reduce the release of 5 million tons of carbon dioxide per year.

They used an artificial semiconductor material, LED, gallium nitride, used to make light-emitting diodes. Due to the low price of the light-emitting diode size and brightness of the advantages compared with the traditional light bulb, it has been used to manufacture bicycle lights, cell phones, camera flash, etc..

But the current manufacturing cost of LEDs are widely used or if the cost is too expensive, this is due to manufacturing a light emitting diode material must be derived from the "sapphire wafer" (Sapphire Wafers), means that the production of light-emitting diode lamp cost will be higher, about 20 pounds. At present, scientists at the center for the study of gallium and nitrogen compounds at University of Cambridge in the United Kingdom have put forward effective solutions, and they will use silicon chips to make light-emitting diodes, thus greatly reducing the cost. County Durham RFMD British company has started to manufacture the prototype, it is expected that the first light emitting diode bulb will be sold on the market within two years.
