Energy-saving lamps, also known as power-saving bulbs, electronic bulbs, compact fluorescent lamps, and integrated fluorescent lamps, are lighting devices that combine fluorescent lamps with ballasts (ballasts). The size of the energy-saving lamp is similar to that of an incandescent lamp, and the interface with the lamp holder is the same as that of an incandescent lamp, so the incandescent lamp can be directly replaced.
The official name of the energy-saving lamp is a rare-earth tri-color compact fluorescent lamp, which was born in Philips in the Netherlands in the 1970s. Under the premise of achieving the same light energy output, such a light source consumes only 1/5 to 1/4 of the power consumption of an ordinary incandescent lamp, thereby saving a large amount of lighting power and cost, and is therefore called an energy saving lamp. Here are some tips on energy saving lamps for your reference.
　 First, the advantages: energy-saving lamp energy-saving calculation method
A family calculates the electricity cost of using 15 bulbs:
1. Ordinary bulb electricity fee: 15 lamps × 40W / only × 5 hours / day × 30 days = 90000W / hour = 90 degrees monthly electricity fee = 90 degrees × 1 yuan / degree = 90 yuan 2, energy saving lamp: 15 Only lamp × 8W / only × 5 hours / day × 30 days = 18000W / hour = 18 degrees monthly electricity costs = 18 degrees × 1 yuan / degree = 18 yuan 3, EEFL energy-saving lamps electricity costs: 15 lights x5w / only x5 hours / Day x30 days = 11250w / hour = 11 degrees that this family can save electricity costs after using energy-saving lamps: 90 yuan - 18 yuan = 72 yuan, you can save electricity costs 864 yuan a year. If the family uses EEFL energy-saving lamps, they can save electricity every month: 90-11=79 yuan, saving 948 yuan in electricity costs in one year.
A textile mill calculates the electricity cost of 100 lamps for 24 hours:
1, the original T8 fluorescent lamp 40W, the actual energy consumption 40W + 10W (ballast) = 50W; 100 × 50W / only × 24 hours × 30 days × December = 43200000W / hour = 43200 degrees annual electricity costs 43200 degrees × 1 yuan / degree = 43200 yuan 2, replacement type T5 energy-saving bracket lamp, the actual power consumption is 26W; 100 × 26W / only × 24 hours × 30 days × December = 22464000W / hour = 22464 degrees annual electricity cost 22464 degrees × 1 yuan / degree = 22464 yuan 3, replaced with EEFL energy-saving lamps, the actual power consumption 5w 200 x5w / only x24 hours x 30 days x12 months = 8640000W / hour = 8640 degrees 4, annual energy saving: 43200-22464 = 20736 yuan EEFL Energy-saving lamps save electricity every year: 43200-8640=34560 yuan
Second, the shortcomings:
Due to the limitation of the working principle of energy-saving lamps, mercury in the lamps is inevitably a major source of pollution. An ordinary energy-saving lamp contains about 5 mg of mercury, which is only enough to be covered with a ballpoint pen tip, but it may cause 1800 tons of water to be contaminated after it penetrates into the ground. Because mercury has a low boiling point, it can evaporate at normal temperature. After the waste energy-saving lamps are broken, the concentration of mercury in the surrounding air can be exceeded by a hundred times. Once the mercury in the human body exceeds the standard, it will destroy the central nervous system of the human body, and the human body can kill by inhaling 25 grams of mercury vapor.
China's energy-saving lamp promotion strategy has been in existence for a long time. In 2008 alone, 62 million energy-saving lamps were promoted nationwide. Until 2009, it was as high as 1.2 billion. According to incomplete statistics, the country has promoted energy-saving lamps up to 200 million over the years. At present, China is still blank in the harmless treatment of energy-saving lamps. The broken energy-saving lamps are sent to the landfill for landfill with domestic garbage. In 2006, China's scrapped mercury-containing lighting appliances were equivalent to 1 billion standard fluorescent lamps of 40 watts, and the amount of mercury released into the atmosphere due to improper disposal reached 70-80 tons.
