December 7, 2009 Central Economic Work Conference closed stressed the need to pay more attention to promoting change in the pattern of economic development and economic restructuring, development of strategic new industries, promoting energy conservation, inhibition of excess capacity, low-carbon economy to carry out pilot efforts to control greenhouse gas emissions, strengthen ecological protection and environmental governance, accelerate the construction of resource-saving and environment-friendly society. Thus, low-carbon, energy-saving concept has been integrated into the main tone of China's development.
With the production, life, city streets and other lighting continues to grow, lighting electricity consumption in the power position in the increasingly apparent. According to the China International Lighting network statistics, developed countries, the proportion of lighting electricity consumption has accounted for 25%. In contrast, despite the relatively low level of economic development in China, but the lighting, the national electricity consumption accounts for more than 12% of total consumption, and an average annual increase rate of 15%. According to an authoritative expert estimates, the 2007 national urban road lighting, for example, if the lighting of urban roads 1 / 3 of replacement energy efficient lighting products, the saving of electricity consumption equivalent to a generating capacity of the Three Gorges Project. Therefore, the National Development and Reform Commission and the United Nations Development Programme (UNDP), Global Environment Facility (GEF) co-operation jointly launched the "China to phase out incandescent light, speed up the promotion of energy-saving lamps" project. As energy-saving alternatives to incandescent lighting products usher in the rapidly growing market is a good opportunity, especially as a revolutionary new light source - LED in the "low carbon", "energy saving" the general trend, even more plugged in to take off wings.
In the triumph of low-carbon economy, the various types of energy-efficient lighting products beautifully, display their talents. However, in this dazzling sight behind the voice of a high energy-saving fluorescent lamps are hidden deadly threat to many unknown. If you can not know the existence of cognitive fluorescent energy saving lamps fatal flaw, let it keep pace with the LED light source and the new drive, then the boom in the back of energy saving, you can see the future China will bear the disastrous consequences.
Multi-disciplinary point of view, either from the perspective of environmental protection, or the comparison of the technical indicators, energy-saving fluorescent lamps should be replaced by the new light source LED:
First, raw materials, pollution and can not be recovered: it was well aware that energy-saving fluorescent lamps which contain pollution killer - mercury, a mercury lamp average of 0.5 mg can cause if they penetrate the ground about 180 tons of water pollution. Currently, there is no scientific way to recycle energy-saving lamp, to prevent contamination. The general approach taken in deep now, but in serious water pollution. Now, many countries are promoting the "energy saving lamps to replace incandescent lamps," understandable from the energy point of view, but from the environmental point of view is not necessarily feasible. Far as incandescent and fluorescent energy saving lamps compared to incandescent high energy consumption, although it does not pollute the environment can be mercury, fluorescent energy saving lamps energy it contains pollution killer - mercury. Let us think, in the development of low carbon economy and the stage in the green economy, China, for example, 1.3 billion people, if you use 5 per person per year energy-saving lamp, for a total 6.5 billion, the equivalent of 3.25 million grams of mercury pollution, if into the ground, will result in 1.17 trillion tons of water pollution, the consequences could be disastrous. This alone, it should withdraw from the stage of history.
Second, the strobe serious: serious stroboscopic energy-saving lamps, about 100-200 times a second strobe. According to statistics, the proportion of myopia is to enhance the students with severe fluorescent strobe classroom, but also to operate in some areas of fine, fluorescent flicker can cause severe fatigue staff, affect the operation of the fine degree of security risk.
Third, the light fades serious: Although the energy-saving lamps manufacturers, especially the T5 tube manufacturers are committed to life 30,000 hours or so, but almost all of the T5 energy-saving application of domestic cases are serious in the light of six months or so bad, seriously affecting the use of environment, lighting quality, and even some industry had to prohibit the use of T5 tubes. T8 T5 tube and pipe replacement, the overall investment is also a great need to replace the whole lamp, the result of six months or so customers only have to re-replacement, intended to saving energy and money, the result is a waste of a lot of money and time.
Relative to the energy-saving lamps, LED lighting has many unique advantages to manifest more in line with "low carbon" and "energy" concept, and with the LED technology progress and application acceleration, will greatly promote the global "carbon" and "energy saving" process.
