The test data given by the authoritative department shows that, to achieve the same brightness, the energy-saving lamp can save 60% to 80% compared with the traditional incandescent lamp, and the life is more than 5 times that of an ordinary incandescent lamp, a 10 watt. The brightness of the energy-saving lamp is equivalent to a 50-watt ordinary incandescent lamp. Replacing five 100-watt incandescent bulbs with 18-watt energy-saving bulbs will reduce the emission of 1 ton of carbon dioxide into the atmosphere in one year, which is equivalent to planting 9 carbon dioxide absorbed by firs with a growth period of 30 years.
According to statistics, lighting consumption accounts for about 12% to 20% of the total electricity consumption. According to China's situation, according to conservative estimates, China's total power generation in 2010 will reach 300 billion kWh, and lighting power will be about 360 billion kWh. The energy saved by half of the lighting is 180 billion kWh, which is equivalent to the annual power generation of the two Three Gorges power stations. In this case, the importance of lighting energy conservation is self-evident.
At present, under the green tide of global energy conservation and environmental protection, lighting energy conservation has naturally become the focus of attention.
On June 5, the Comprehensive Work Plan for Energy Conservation and Emission Reduction issued by the State Council pointed out that it is necessary to “accelerate the implementation of the ten key energy-saving projectsâ€, and it is more clear that it is necessary to “promote 50 million high-efficiency lighting products, and the central state organs take the lead in replacing energy-saving projects. light".
It can be seen that an important item in energy conservation and emission reduction is lighting energy conservation. So, what is the current situation of urban lighting energy conservation? The reporter recently visited Shijiazhuang.
1, home lighting: the high recognition of the people, product standards need to be standardized
“Energy-saving lamps save electricity and save money.†Liu Deyu, a retired employee of the provincial capital who has used energy-saving lamps for nearly two years, is full of praise for energy-saving lamps. Mr. Liu used light bulbs, halogen powder lamps and three primary color lamps. "My family has a total of more than 10 lights, the earliest use of light bulbs, and later replaced with halogen powder lamps bought in the lighting city, electricity costs can save a few dollars, but halogen powder lights do not wish
Later, I saw from the newspaper that the Hebei Province Power Demand Side Management Guidance Center offered energy-saving lamps. I bought more than 10, "This is a three-color lamp, which is bright and energy-saving. The monthly electricity bill is 10 yuan. It’s almost two years now, the lights are not bad, how do you calculate, how much money saved?†On June 27, Liu Deyu told reporters.
Compared with Liu Deyu’s praise for energy-saving lamps, Mr. Liang, the provincial capital, does not agree: “Energy-saving lamps save electricity and save money.â€
Asked the reason, he told reporters that he bought 5 energy-saving lamps from a lighting store some time ago. The owner promised that the energy-saving lamps could save about 80% of electricity and have a life expectancy of 2 years. But in two months, the 5-inch energy-saving lamp has broken 3 ç›. Ordinary incandescent lamps are one yuan, and the cheapest energy-saving lamps are also 3 to 4 yuan. The provincial electricity bill is not enough to light the money. It is no wonder that Mr. Liang sent such feelings.
The reporter learned that users who use three-color energy-saving lamps generally feel that they save money and save money. However, many users who use halogen powder or mixed powder energy-saving lamps feel that saving electricity does not save money.
The staff of the provincial power demand side management guidance center said that the halogen powder lamp has low luminous efficiency and short life, and should not be called energy-saving lamps at all. It is this part of the lamp that affects the reputation of energy-saving lamps.
Into the provincial large-scale lighting city, in addition to the traditional light bulbs and emerging LEDs, there are numerous types of tubular lamps that rely on phosphors to emit light. On the shape, there are straight tube, ring shape, shape, U shape; on the luminescent powder material, there are halogen powder lamp, silver powder lamp, three primary color lamp, pure three primary color lamp; on the price, the same wattage The lamp has 3 or 4 yuan, and there are 8 or 9 yuan, and 10 yuan and 14 yuan. On the life, there are three or four months, and there are also two to three years... All of these phosphor tube lamps are all referred to by sellers as "energy-saving lamps."
