The LED technique makes the ice removal of mercury pollution in refuse

19, 2009, the construction workers have been closed in Harbin, the world of ice and snow, and began to use large machinery to remove ice and snow landscape. This year due to Harbin using energy saving LED ice, they will be removed without causing environmental pollution.

Reporters learned that the Harbin ice and snow festival over the past 30 years, the total consumption of fluorescent lamps has reached millions, each containing only about 20-45 mg of mercury in the fluorescent lamp, and normal people if consumed by 0.1 grams of Mercury will be poisoned to death.

Almost all of the traditional light sources contain mercury, lead and arsenic compounds, there is no lighting for harmful substances are effective ways of recycling, mercury and other heavy metals and harmful substances were abandoned directly in the soil, will cause pollution to the environment. And to solve the problem of fluorescent lamp pollution is "LED", that is, "light-emitting diode", a kind of electronic energy can be converted into light energy.

Provincial Science and technology department director Zhao Min said: "I hope the Harbin ice can fully replace fluorescent lamps with LED lights, LED lights that can be used repeatedly. "Snow world Zhao Hongjun said:" this year I met in France, Russia, Australia, Spain and other countries to the ice and snow world an interview, when it comes to ice environmental problems, they are very concerned, because these countries have not applied ice LED technology, they think Harbin LED ice science and environmental protection, the other is worth national reference. "

It is understood that, in early 2007, the provincial science and technology department in Zhaolin Park "ice LED landscape lighting" experiment, a big success. Two years later, the office of science and technology and the ice world invested heavily to promote LED development of ice.

In the winter of 2008, 40% of the world's ice and snow landscape used LED technology; in the winter of 2009, ice and snow in the world landscape of the use of LED technology.
