Energy-saving lamps little knowledge

Energy-saving lamps, also known as light bulbs, electronic light bulbs, fluorescent lamp, compact fluorescent lamps and one piece design refers to the fluorescent lamp and ballast ( Ballast) Combined into a whole lighting equipment. The size of the energy-saving lamp and incandescent lamp, and lamp holder interface also is the same as the incandescent light bulb, so you can directly replace the incandescent lamp.

is the official name of the rare earth tricolor energy-saving lamps compact fluorescent lamp, was born in philips, the Dutch in the 1970 s. Under the premise of this kind of light source in the same light output, use up 1/5 to 1/4 of ordinary incandescent lamp of electricity, which can save a lot of lighting electric energy and cost, therefore is called the energy-saving lamps. Here are some little knowledge about energy saving lamps, for your reference.

the one family, advantages of energy-saving lamps, energy-saving calculation method by using 15 bulbs charge calculation 1, ordinary light bulbs charge only 15 only light x 40 w/x 5 hours/day * 30 days = 90000 w/h = 90 monthly electricity = 90 x 1 yuan / 2 = 90 yuan, energy-saving lamps of electric lamp only 15 x 8 w/x 5 hours/day * = 18000 w/h = 18 degrees 30 days a month electricity = 18 x 1 yuan/degrees = 15 only 18 yuan 3, EEFL energy-saving lamps electric lights x5w/only x 5 hours/days x = 11250 w/h = 11 degrees is the family after the use of energy-saving lamps can save electricity, 90 yuan a month - 18 yuan = 72 yuan, can save electricity, 864 yuan a year. Such as the family after use EEFL energy-saving lamp can save electricity - 90 a month 11 = 79 yuan, can save electricity, 948 yuan a year. A textile factory calculated at 100 light electricity 24 hours 40 w 1, original T8 fluorescent lamp, the actual energy consumption of 40 w + 10 w ( Ballast) = 50 w; 100 x 50 w / * 30 days * 24 hours in December 43200000 w/h = = 43200 years electricity costs 43200 degrees 2 x 1 yuan/c = 43200 yuan, replace type T5 energy-saving lamps, the actual power consumption of 26 w; 100 * 26 w/only * * 30 days * 24 hours in December 22464000 w/h = = 22464 years electricity costs 22464 degrees by 1 yuan/c = 22464 yuan 3, replace EEFL energy-saving lamps, the actual power consumption of 5 w 200 x5w/x12 x30 x24 hours day month = 8640000 w/h = 8640 degrees to 4, and electricity saving 43200 - a year EEFL energy-saving lamps power saving each year 43200-22464 = 20736 yuan 8640 = 34560 yuan

2 and disadvantages because of the limitation of working principle of the energy-saving lamp tube of mercury will inevitably become a pollution source. 1 only about 5 mg of mercury content of ordinary energy-saving lamps, only with a round bead pen, but after seep into the underground might produce 1800 tons of contaminated water. Due to the low boiling point of mercury, room temperature can evaporate, abandoned after energy-saving lamp tube broken, instantaneous can make around one hundred times on the chroma of mercury in air. And once in the body's levels of mercury can damage a person's central nervous system, and the human body a suction 25 grams of mercury vapor can be lethal.

China has long been a energy-saving lamps promotion strategy, promote energy-saving lamps nationwide in 2008 alone, 62 million, until 2009, 1. 2 billion only. According to incomplete statistics, since the past years, the country to promote energy-saving lamps is as high as 200 million. At present, our country in the energy-saving lamps harmless treatment or blank, broken CFL with domestic waste sent to landfill dumps. In 2006 our country scrap mercury lighting (40 tile standard fluorescent of only 1 billion, released into the atmosphere environment due to improper disposal of the amount of mercury in 70 ~ 80 tons.

3, the choose and buy of energy-saving lamps in general, compared to traditional incandescent lamp, energy-saving lamps more environmental protection and energy saving. However, energy-saving light pollution hidden trouble should not be ignored. The personage inside course of study advice, first of all, the government should encourage community, environmental groups such as recycling energy-saving lamps in the form of group, and to the enterprise to the corresponding recycling subsidies. In addition, the enterprise should try to cut down the content of mercury in the energy-saving lamp production.

in addition, citizens also should try to choose 'China's energy efficiency label' brand energy-saving lamps, to reduce the elimination rate of energy-saving lamps. It is reported that a high quality energy-saving lamps can be used for 5 years, and inferior of energy-saving lamps may be blackened with only a few months. In addition, now do not contain mercury LED bulbs also gradually towards the domestic market, just price is a little bit higher, capable people can consider to choose and buy.

at the same time, the personage inside course of study, called for in the drive and enjoy the process of environmental protection and energy saving products, also have to face the new pollution.
