Blue LEDs will help Peter save Bashny.Net

500 million rubles per year — that's how much the city authorities intend to save with the theory of blue LEDs, which was awarded this year's Nobel prize in physics.





Recall, the prize was awarded to three scientists from Japan, Hiroshi Amano, Isamu akasaki and Shuji Nakamura. Japanese researchers have invented and developed a powerful and energy-efficient blue led emission spectrum.

As scientists have calculated, if you equip all the lights of St. Petersburg led lamps, the city will annually spend half a billion rubles less. By the way, similar technology is already used on Svetlanovsky square in the Northern capital. The efficiency of LEDs is two times higher than energy-efficient lamps. They do not harm the environment and last longer.

According to the General Director of Group of companies "Svetlana-Optoelectronics" Alex Mokhnatkin, led bulbs have another advantage: "no matter How much we repeated this focus, the light will Shine. There is nothing to fight for. There is nothing. This is a fee with the sapphire."

Note that in Saint-Petersburg adopted a program "Bright city", which runs until 2022. By this term it is planned that 70% of the streets are illuminated with led lamps.
