Research: LED lamps for the national classroom next year, according to the province 1 billion 600 million yuan

Do you know what kind of lighting is used in the classroom, how much electricity is consumed in a day? Do you know how much electricity can be saved in a classroom by using an energy-efficient LED lamp? So if the national classrooms are using LED lights, a year for the country to save much electricity? Perhaps you have never thought about these issues, as well as Xiao Bian, but Shenzhen Yaohua School Environmental Protection Agency Hou Kaiying and his little friends have been studying these issues.

Recently, Hou Kaiying, led by the environmental protection agency Yaohua experimental team from the classroom to study the energy saving program, but also made no small achievements. The experimental study on the effect of energy saving and environmental protection on the classroom lighting using LED lamps was published in the Journal of China Science and technology, which is in charge of the national science and technology department. According to the editor of the magazine, the Journal rarely published research papers written by middle school students.

According to the research group showed that if the national total of 3 million 400 thousand classrooms for the replacement of all LED lamps, a year can save about 2 billion 400 million of electricity consumption of lighting (the equivalent of a large coal-fired power station generating capacity); reduce the consumption of about 1 million tons of standard coal; reduce carbon dioxide emissions by about 2 million 300 thousand tons; electricity savings of about 1 billion 600 million yuan.

The LED lighting energy-saving environmental protection and economic and other related data collection period: a full semester experiment group plan, from September 2, 2013 to January 24, 2014, as the data collection period, a total of 21 weeks, excluding weekends and holidays, days after the normal study for 101 days. Data acquisition frequency is collected once a month, the time for the last day of the month after the end of the afternoon after 17: 30.

The team members began to purchase the materials needed for various experiments. 18 LED lamp, model KK-T8-4FW-15, the price of 60 yuan / root; 2 watt hour meter, model ZJ120-001, a total of $130; 1 illuminance meter, model AS823, cost $253. Under the guidance of the school electrician, the experimental group has installed and debugged the lamps and meters.

The team chose two used the light time is basically the same as the classroom, one room to continue to use the existing fluorescent lamp tube, a fluorescent lamp classroom will be substituted for LED tube, and ensure the two classroom illumination roughly the same. The use of watt hour meter to measure the power consumption of two classrooms for a period of time, so as to calculate, compare and analyze.

After repeated experiments and statistical calculation, experimental group has made a scientific and accurate data: the use of LED lamp A512 using fluorescent lamp A412 than the classroom classroom 1 years can save electricity 744.4 degrees, to reduce carbon dioxide emissions 715 kg (according to the Chinese life Zhou Qiji foundation database CLCD, to produce 1 kwh of electricity to produce carbon dioxide emissions by about 960 g). According to the Shenzhen city residential electricity charges 0.68 yuan / kWh calculation, a LED, every year can save electricity 506.19 yuan, and the fluorescent lamp tube of a classroom replacement cost required for the purchase of LED lamp is 1080 yuan, which means that only two years time, the use of LED lamps save electricity you can recover the cost of purchase.

Yaohua school a total of 67 such as the size of the standard classroom A512, if all replaced by LED lamps, the annual savings of lighting electricity consumption 49 thousand and 900 degrees, saving electricity costs $33 thousand and 900. Moreover, due to eliminate the stroboscopic phenomenon of traditional lamps, for primary and secondary school students to protect the eyesight is very good.

According to the results of the experiment, the environmental protection agency's experimental group wrote an experimental study on the effect of energy saving and environmental protection on the classroom lighting using LED lamps. Now, led by Hou Kaiying, the experimental team first proposed to Yaohua school, in the future renovation of the classroom, the priority to replace the LED lamp. This can not only save energy and environmental protection, but also can effectively reduce the cost of running schools, but also through the use of energy-saving facilities to promote the concept of energy conservation and environmental protection. They also want to suggest to the national school, consider the classroom lighting as soon as possible to replace the LED lamp.
