White light.

Can humanity achieve a clear light screen, with out the harm full effects of doing damage to the retina by flash. a communication tool all the use of a cheep alternative rather than expensive consumption of electricity? Can this be the change in this long awaited evolution.

When the wind up radio was invented and obtained the Nobel Prize for innovation making millions in sales? This was due to the very fact that its simplicity made it the first of its kind in the world. It was only then the scientist realist to make products more genomic and tailored to the market. Where the remotest regions and civilizations could gain benefits true the product use. This was not the only factor people now like to be on the move, in cars and other areas of transport that leaves a demand for common utility in basic services and a need to able to use gadgets.

Scientists at the Cambridge University-based Centre for Gallium Nitride solved that problem by growing it on silicon wafers. A manufacture, RFMD in County Durham, has begun work on production prototypes and the first "Led bulbs" could be in the shops within two years. The head of the centre, Professor Colin Humphreys, said: 'This could well be the holy grail in terms of providing our lighting needs for the future. 'We are very close to achieving highly efficient, low-cost "white LEDs." 'That won't just be good news for the environment. It will also benefit consumers by cutting their electricity bills. 'It is our belief they will render current energy-efficiency bulbs redundant.
