Answer mercury pollution plagued by energy-saving lamps with what favored?

According to the Yangcheng Evening News reported that the "Earth Hour" this year there are 172 countries or regions, more than 7000 city involved, there are more than 1400 landmarks and nearly 40 UNESCO World Heritage sites in response to the lights.

Some people ask, how much electricity can be saved? To statistics it seems a bit difficult, but we should know that its real purpose is not to save the hours of electricity, but to lead a "news effect", arouse the public to environmental and energy issues, seriously consider environment, climate and earth's future.

World Earth Day April 22nd". The author believes that active participation in "Earth Hour" activities at the same time, it is necessary to respond to this year's Earth Day theme: "cherish the earth's resources, change the mode of development, improve the efficiency of resource use, such as" repeat "to change the light bulb". In 2011 the national development and Reform Commission has issued "Chinese incandescent the light route map", this will gradually ban the import and sale of ordinary incandescent lamp, incandescent lamp and so completely out of the market before 2016. Change a light bulb, perhaps more than the earth hour to save electricity, save money.

Energy saving lamp life long, more environmentally friendly, more energy saving

Edison lit up from 1879 the first light carbon filament incandescent lamp, we began to get used to lighting lamp. By heating the filament to the incandescent state, the use of thermal radiation emitted visible light source incandescent lamp, has become an indispensable thing in our lives.

But with the continuous development of lighting technology, a new generation of energy-saving lamp, fluorescent lamp and ballast will be combined into an overall lighting equipment, actually called rare earth three color compact fluorescent lamps - will completely replace the incandescent lamp, fluorescent lamp, lighting tools become more environmentally friendly energy saving, long life.

According to estimates, China's lighting electricity accounts for about 12% of the useful electricity. With the family as a unit, a 60 watt incandescent bulb can produce a light that can be used to meet the needs of the family life, so a single watt watt hour lamp can also meet the same lighting needs. Replaced by a higher technical content of LED, it is only about 3.5 watts. And after the lights, the monthly electricity tariff is only the previous 1/15. Some people have a look, if all of the incandescent lamps are used for the replacement of energy-saving lamps, is expected to save 48 billion kwh per year.

Because the energy-saving lamps than ordinary incandescent lamp 60%-80%, the service life of 4-8 times, the brightness is 5 times the ordinary lamp. In the long run, the use of energy-saving lamps is far more than the incandescent electric power savings, but also to save money for the bulb.

A study by the U.S. Department of energy and the environmental protection department jointly set up, mainly for consumer electronics products, energy saving plan "Energy Star" the report also said that if all of the families in the United States will only replace the incandescent lamp energy-saving lamps, the annual electricity saving 3 million is enough to reduce the family. Carbon emissions equivalent to 800 thousand car emissions.

Confused: mercury pollution?

However, the biggest problem is still the price of energy-saving lamps expensive, difficult recovery.

First of all, because of the production technology and other reasons, it is almost 3-6 times the price of incandescent lamps, or even higher. Now about to enter the era of smart home, the new energy-saving lamps are also combined with smart phones, ideas and other high-tech control to enter the market, the price will be even more expensive.

It is important that energy-saving lamps are also complaints of mercury pollution.

First to find out its luminous principle: fluorescent tube filled with argon neon mixed gas and mercury vapor tube, the inside wall is coated with phosphor fluorescent paint, electricity, steam will emit ultraviolet mercury, and fluorescent paint will absorb ultraviolet light, thereby releasing the visible light. The color of the visible light depends on the proportion of the phosphorus content, so the energy-saving lamp can have so many different colors.

It is not difficult to understand that each energy-saving light bulbs contain a small amount of mercury. It is also important to understand that the mercury content of each bulb is usually less than 5mg. If they are gathered into droplets, the diameter is about 1.1 mm. In the process of using, the mercury in the energy-saving lamp can not pollute the environment, and can not cause harm to human body. On the contrary, because of energy saving, the use of energy-saving lamps will reduce the generation of coal combustion caused by mercury pollution.

If you want to say that energy-saving lamps have mercury pollution, it is mainly due to the lamp is broken. But according to the U.S. Environmental Protection Agency (EPA) estimates, in 2009 the total sales of 27 million 200 thousand energy-saving lamps, energy saving lamps if these were all broken landfills, they will indeed increase 0.12 tons of mercury emissions to the environment, but this is only a 0.12% increase in the basic annual anthropogenic emissions of mercury on the. So, as long as the proper recovery, energy-saving lamps of mercury pollution in the environment is actually very small.

But it is worth reminding, if at home, accidentally breaking energy-saving lamp, it is best not to immediately clean, should open the window ventilation and the withdrawal of the room, such as mercury vapor leaks from the tube in dissipated in the air, then enter the room should be cleaned. This is because Mercury can be volatile at room temperature, energy saving lamps broken, the moment can make the air concentration of mercury over a hundred times.

Rumors: carcinogenic?

At present, the global LED industry has entered a rapid development period, in 2013 the global LED market size of $12 billion 400 million, in 2020 will reach about $150 billion. But some time ago, WeChat began to spread on a energy-saving lamp radiation carcinogenic post:
