Development status of Russian LED light source

Not long ago, the Russian company showed nano group's "features are, from society for" company produces LED lights, lighting effect of the LED lamp can reach 60W incandescent lamp, but the energy consumption only 1/6 of incandescent lamp, the service life can reach 50 thousand hours. The LED lamp is planned for sale in Moscow and St Petersburg in September at a price of nearly 1000 rubles, and if sales are good, manufacturers are committed to cutting the price to 300-350 rubles.

The price of lighting products in many countries has long been not in accordance with the laws of the market, but often linked to ecological protection issues. According to Russia's "energy conservation and energy efficiency" law, from 2011 onwards, Russia will stop more than 100 watt incandescent lamps and power production in 2012 to stop a 75 watt incandescent lamp and power production, 25 watt incandescent lamp in 2014 to stop production (Russia basically no less than 25 watt incandescent lamp for indoor lighting).

In 2007, the first such legislation in some U.S. states, the main goal is to fight global warming. Since 2009, Europe has banned the 100 watt incandescent lamp sales, banned 60 kilowatts last year, this year from 40 watts, 25 watts incandescent ban will begin next year, and by 2016 will be issued by the "special act" limit the sale of all incandescent lamps. China will also from October 2012 to prohibit the sale of more than 100 watt incandescent lamps and lighting. Since October 2014, the sale of 60 watts and above incandescent lamps. Since October 2016, the sale and import of 15 watt or more incandescent lamps.

The official name of the energy-saving lamp is rare earth three primary compact fluorescent lamp, was born in 1970s in Holland, PHILPS. The traditional fluorescent lamp is equipped with two filaments. The filament is coated with an electron emission material of three yuan carbonate (barium carbonate, strontium carbonate and calcium carbonate), commonly known as electronic powder. The filament is alternately used as cathode and anode under AC voltage. The inner wall of the lamp tube is coated with fluorescent powder, and the tube is filled with argon and a small amount of 400Pa-500Pa pressure. After power up, liquid mercury evaporated into a vapor of 0.8 Pa. Under the action of the electric field, the mercury atom is excited from the original state into the excited state, and then spontaneously transitions to the ground state, and the ultraviolet radiation of 253.7nm and 185nm is radiated to release excess energy. The phosphor emits visible light after absorbing ultraviolet radiation. Because most of the energy consumed by the fluorescent lamp is used for generating ultraviolet rays, the luminous efficiency of the fluorescent lamp is much higher than that of the incandescent lamp.

LED light-emitting principle light emitting principle with incandescent and energy-saving lamps are different, the energy conversion efficiency of the LED light source is very high, can theoretically reach only 10% of the energy consumption of incandescent lamp, fluorescent lamp can also be compared to reach 50% of the energy saving effect, which itself does not contain toxic and harmful substances, under normal circumstances, the service life is 100 thousand hours. These advantages of the LED light source from the environmental protection and reduce energy consumption is undoubtedly of great significance, which doomed LED light will eventually replace the traditional incandescent and energy-saving lamps, lighting has become the ideal light source.
