Since the farewell to the flare lighting, the electric light has become inseparable from human beings. In China, electricity consumption for lighting accounts for about 12% of the total electricity consumption of the whole society.
Today's electric light, like it was just born, once again became a hot spot: the central government proposed to make the greatest determination, spend the most effort to save energy resources, and promote high-efficiency energy-saving lighting system, which is becoming the "Eleventh Five-Year" China's top ten energy-saving One of the key projects.
No matter how far the era of energy-saving lighting is from us, how to choose lamps and lamps is not as high-profile as it is today.
Ending incandescent lamps can "recreate" a Three Gorges power station
This is an amazing account: If all the existing ordinary incandescent lamps are replaced with energy-saving lamps, China can save more than 60 billion kWh a year, close to the annual power generation of the Three Gorges Power Station!
"Our agencies have completely eliminated incandescent lamps and installed more than 5,000 energy-saving lamps," said Li Yanchun, director of the Office of the National Development and Reform Commission. Under the unified deployment of the State Council's Bureau of Administration, since last year, the National Development and Reform Commission and other government departments and institutions have replaced all incandescent lamps with energy-saving lamps.
In the lighting market, more and more energy-saving lamps appear, and there is a great potential to replace incandescent lamps. A person in charge of an energy-saving lamp company in Zhejiang Province said that only 6% of incandescent lamps are converted into light energy, and the rest of the energy is converted into heat energy, which is wasteful. Energy-saving fluorescent lamps consume less power than incandescent lamps that use tungsten filaments as illuminants. With 20% electricity, you can emit as much light as an incandescent lamp.
At the beginning of March this year, a rare blizzard in the northeast affected the Dalian power grid, and many communities were cut off from electricity. In Xiao Zhiguo, the chairman of Dalian Luming Technology Group, slippers, carpets to the bathroom, and telephone receivers can all be illuminated, and you can find what you want without turning on the lights. Here, there are both semiconductor lighting technology and new luminescent material technology.
Xiao Zhiguo, who has been committed to the research and development and marketing of semiconductor lighting technology for many years, said that compared with energy-saving fluorescent lamps that are prone to mercury pollution, semiconductor lighting uses a cold light source, which is not only pollution-free, but also has a power saving efficiency of over 90%. In fact, semiconductor lighting has quietly entered people's lives, from high-tech products such as mobile phones, computers, digital cameras to automobiles, instrumentation indicators, and urban landscape lighting, everywhere.
When “energy saving†encounters “no moneyâ€
China is the world's largest producer of energy-saving lamps. In 2005, the output of energy-saving lamps reached 1.7 billion, accounting for 90% of the world's total output, but more than 70% of them are exported abroad. In Ningbo, there are more than 100 enterprises producing energy-saving lamps. The annual export value is several hundred million yuan, but domestic sales are only several million yuan. Why is the energy-saving lamp in the country encountered in the wall?
"Energy-saving lamps are expensive, and the quality is not satisfactory. If you don't move, you will be blind." 1 Changchun citizen Wang Chunhua complained, "Electricity is a festival, but the money is not saved. In the first half of the year, almost all the energy-saving lamps she bought at home. Change it again. Consumer guidance experts believe that when “energy-saving†products are not “saving moneyâ€, they are destined to be cold in the market.
