Treasury Prices

The growth trend in electricity prices seen throughout the world, and expected liberalization of the Russian energy market in 2012 may contribute to higher growth of prices on the energy market. Thus internal gas prices are expected to increase by more than 25% per year, starting next year. As a result, by 2015 in the country, they can grow more than fourfold. Due to the fact that 40% of all electricity produced by gas, the effect of rising prices for gas at the power market will be very important. Now electricity is very cheap in Russia: the Nordic power market NordPool wholesale prices for electricity and a half times higher than those in European Russia, in Western Europe, electricity prices twice as high in Italy – in four. Abroad in the development of energy-saving subjects invested fortunes.

In China in 2006 adopted a large-scale program to support private business engaged in the development of led projects, it would cost the Treasury at $ 754 million. There have calculated: If you change only one third of the country's lamps and fixtures, will be spared the power that produces the largest npp in the world. Worth it. In the U.S., a similar program until 2011, the Government allocates about $ 1 billion. We were on such investments represent only a dream. And despite the fact that the standard calculation, we consider only the direct savings, and set of proxy indicators, such as reducing energy shortages, the decline in new construction, reducing the consumption of cables and wires, etc., give the effect that actually reduces the 2-3-year-old payback period of led lamps, at least in half. Macroeconomic benefits of led lighting: 1.

Organometallic Epitaxy

18. What determines the service life of LEDs? It is believed that the LEDs are extremely durable. But it's not quite true. The larger current is passed through the led during his service, the higher the temperature and the faster the aging occurs. Therefore, the lifetime of power LEDs is shorter than that of low-power signal, and now stands at 20 – 50 thousand hours. Aging is expressed primarily in the reduction of brightness.

When the brightness reduced by 30% or half of the led must be changed. 19. 'Port' is the color of the led over time? The aging of the led is connected not only with a decrease in its brightness, but with a change in color. There are currently no standards which would allow to quantify the change of color LEDs in the aging process and compare with other sources. 20. Not bad for a led for the human eye? The emission spectrum of the led close to monochromatic, what it's fundamental difference from the spectrum of the sun or incandescent lamps. Is this good or bad – is not known for sure, because as far as I know, serious research in this area never carried out.

There are no data on the harmful effects of LEDs on the human eye is missing. 21. Which of today, there are manufacturing technology of LEDs and led modules? With regard to crystal growth, then basic technology – Organometallic Epitaxy. For this process requires especially pure gases. In the modern facilities provided for automation and control of gases, their separate threads, fine-tuning gas temperature and substrates.
