On the 19th, construction workers have closed the Harbin Ice and Snow World Scenic Area and began to use large machinery to dismantle the snow and ice landscape. Since Harbin has adopted energy-saving and environmentally-friendly LED ice lamps this year, it will not cause environmental pollution after dismantling them.
The reporter was informed that the total number of fluorescent tubes consumed by the Harbin Ice and Snow Festival has reached several million in the past 30 years. Each fluorescent lamp contains about 20-45 milligrams of mercury. Normal people who consume 0.1 grams of mercury will be poisoned and killed.
Almost all traditional light sources contain mercury, lead and arsenic compounds. At present, there is no effective way to recycle harmful substances from lighting sources. Heavy metal hazardous substances such as “mercury†are directly discarded in the soil, causing certain pollution to the environment. What solves the problem of fluorescent tube pollution is "LED", which is a "light-emitting diode", an electronic device that converts electrical energy into light energy.
Zhao Min, director of the Provincial Science and Technology Department, said: "I hope that Harbin Ice Light can completely replace fluorescent lamps with LED lights, because LED lights can be used repeatedly." Zhao Hongjun of the World of Ice and Snow said: "In the past two years, I have received France, Russia, Australia, Reporters interviewed by Spain and other countries in the world of ice and snow, they all attach great importance to the environmental protection of ice lamps, because the ice lamps in these countries have not applied LED technology, they believe that Harbin's LED ice lights are scientific and environmentally friendly, which is worth learning from other countries."
It is understood that in early 2007, the Provincial Science and Technology Department conducted the "LED Ice Light Landscape Lighting" experiment in Zhaolin Park, which was a great success. In the following two years, the Science and Technology Department and the Ice and Snow World invested heavily in the development of LED ice lamps.
In the winter of 2008, 40% of the ice and snow world landscape used LED technology; in the winter of 2009, 90% of the ice and snow world landscape used LED technology.
