energy saving led light fluorescent creation of environmental protection

LED lighting for the national classroom lighting in the province 1.6 billion

You sit in the classroom and study under bright lights. Do you know how much electricity the classroom lighting consumes? Do you know how much energy the classroom can save by using energy-saving LED lighting? So if all the classrooms in the country use LED lights Perhaps you and the author as usual never thought about these issues, but the Shenzhen Yaohua School of Environmental Protection Hou Kai and his small partners have been studying these issues.

In addition to regular environmental promotion activities and environmental volunteerism, the Environmental Protection Agency’s blog will regularly update environmental news and various environmental knowledge. The Environmental Protection Agency will also monitor the PM2.5 concentration of the school playground every day. Environmental protection community’s WeChat public number published in order to facilitate school students to keep abreast of environmental information.

Recently, the experimental group of Yaohua Environmental Protection Society headed by Hou Kai-yi studied the energy-saving plan of the classroom, and achieved considerable results, which was affirmed by the school and the society. They do “on the use of LED lighting classroom lighting energy efficiency and economic efficiency of the experimental study” in the national science and technology departments in charge of the national academic journals “China Science and Technology magazine” published. According to the magazine’s editor, this magazine published a rare junior high school students before writing research papers. The study also won the “My Chinese Dream – I am a small scientist of the future” activities selected first prize and the “2014 we love science scrambling to do scientific small person” activities such as first prize and other awards.

Light bulbs cause a whim

Night quietly, as if the earth fell asleep. Houkai is at home under the Led lighting fluorescent replacement fixtures to concentrate on reading. He seems to forget the time, immersed in this quiet and beautiful study. Suddenly, only to hear “pop -” to a sound, the Led lighting fluorescent replacement fixtures light bulbs exploded. The room, suddenly become a dark.

Kai Ying quickly took a light bulb to change. Just want to take the bad bulb to hear, “Oh” sound, Kai Ying’s hand was hot a little! Light bulb for good, just that scene, but also in the minds of Kai Ying flash. He thought, why is that bulb so hot? That bulb on the heat really big ah! If you do not change into a hot bulb to avoid heat consumption, and more environmentally friendly, energy saving, durable, that good ah! Flash, pour moment, let him excited, no sleep, he can not help but secretly applauded in my heart.

Kai Ying first access to a large number of online information. He learned that human lighting tools have been developing, from ancient candles, oil Led lighting fluorescent replacement fixturess, to Edison invented the incandescent Led lighting fluorescent replacement fixtures, and later to the widespread use of fluorescent Led lighting fluorescent replacement fixturess. Now, man has invented the LED lighting. Compared to traditional fluorescent Led lighting fluorescent replacement fixturess, LED lighting has many advantages.

The first is energy saving. LED Led lighting fluorescent replacement fixturess with high luminous efficiency, can save a lot of electricity, can reduce the power plant carbon dioxide and other gases. Second, safety and health. LED lights will not emit ultraviolet radiation, harmless to the human body; the use of DC drive, eliminating the traditional lighting stroboscopic phenomenon, low color temperature, color rendering index, can better protect eyesight. In addition, LED tube does not contain lead, mercury and other harmful substances, accidentally broke will not cause the spread of toxic heavy metals. And secondly, the service life is long. A LED Led lighting fluorescent replacement fixtures rated life is generally tens of thousands of hours, or even more than 100,000 hours, while the ordinary fluorescent Led lighting fluorescent replacement fixturess in the 10,000 hours or less.

In understanding the various advantages of LED Led lighting fluorescent replacement fixturess, energy-saving LED home improvement program began. Kai Ying first recorded at home before the use of LED lights power consumption, and then the home of the bulbs all replaced the LED energy-saving Led lighting fluorescent replacement fixturess, and power consumption, heat, room brightness for a simple test. After replacing the LED lights, the home lighting becomes more soft, the room brightness does not reduce, but the home power consumption reduced, the bulb is not so hot below. See their transformation plan to achieve a predetermined energy-saving targets, that moment, Kai-Ying feel the joy of success.

The experimental group was in action

LED energy-saving home improvement plan with the initial results, Kai Ying thought, if the school can also use LED energy-saving Led lighting fluorescent replacement fixturess, is not it better? Although LED lighting has so many advantages, but the lack of these advantages intuitive Feel, coupled with LED Led lighting fluorescent replacement fixturess than ordinary fluorescent Led lighting fluorescent replacement fixtures price is higher, so in real life, people for the use of LED Led lighting fluorescent replacement fixturess have not yet reached the point of popularity of large area.

Therefore, Kay Ying recruited some of the small environmental partners, formed an experimental group, organized a number of experiments on the LED lighting energy efficiency and economic efficiency of the measured test.

During the data collection period, the experiment team planned to take a full semester, from September 2, 2013 to January 24, 2014, for a total of 21 weeks during the data collection period, with a deduction of 101 on weekends and holidays day. Data collection frequency is collected once a month, the time for the last day of the month after class after 17:30.

Use their brains to raise funds

But the experiment requires financial support, Kai-ying and his small partner to save the usual pocket money for experimental funds, not to parents reach out, do not give the school trouble. In order to obtain the support of the students and schools for the experiment, they took advantage of various opportunities to introduce their own ideas of environmental protection and energy conservation, and many teachers and students were touched by them and provided support and assistance for the experiment.

LED Led lighting fluorescent replacement fixtures: Model KK-T8-4FW-15, the price of 60 yuan / root, a total of 18 Led lighting fluorescent replacement fixturess spent 1080 yuan; meter: buy on Taobao, model ZJ120-001 2 total power meter Cost of 130 yuan. “This is a small account of the experimental group note the use of experimental funds, in order to buy cheap and experimental equipment, Kai Ying them Take the trouble to carefully selected, shop around, from which also greatly exercise their cost control concept, a small age, but also learned how to bargain.

Under the guidance of the school electrician, the experimental group on the Led lighting fluorescent replacement fixturess and watt-hour meter installation and commissioning. In this, the children eat a lot of pain. Kai Ying before learning the knowledge of the circuit, and now just row on the use, start “small electrician” to imitate.

Juvenile energy saving recommendations

The experiment group chose two classrooms with basically the same Led lighting fluorescent replacement fixtures time. One of the classrooms continued to use the existing fluorescent tubes. The other classroom replaced the fluorescent tubes with LED Led lighting fluorescent replacement fixturess and ensured that the illuminance of the two classrooms was about the same . Using the meter to measure the electricity consumption of two classrooms for a period of time, so as to calculate, compare and analyze.

During the experiment, the experimental group to overcome a lot of difficulties, for example, in order not to affect the students of the class, all the experimental data statistics and so on, are in the afternoon after 5:30, other students are happily after school Go home, Kai Ying their experimental work has begun. Sometimes, in order to get more accurate data, Kai Ying often late to go home, his parents stay for the food are cold.

After repeated experiments and statistical calculations, the experimental group of experiments to obtain scientific and accurate data: the use of LED Led lighting fluorescent replacement fixturess A512 classrooms than the use of fluorescent tubes A412 classroom 1 year can save 744.4 degrees, reduce CO2 emissions 715 kg (according to China Life cycle database CLCD, the production of 1 kWh of electricity generated CO2 emissions of about 960 grams). According to the Shenzhen residents charge standard 0.68 yuan / kWh, a LED classroom can save electricity 506.19 yuan per year, and a classroom fluorescent tubes replaced with LED Led lighting fluorescent replacement fixtures for the purchase cost of 1080 yuan, which means With only two years, the use of LED Led lighting fluorescent replacement fixturess can save the cost of electricity to recover its procurement costs.

Yaohua School is a full-time school, located in Futian District, Shenzhen, the existing primary, middle and high school level of the three schools, a total of 67 classes in 1758 students, 164 teachers. The school a total of 67 such as the size of the A512 standard classroom, if all replaced with LED Led lighting fluorescent replacement fixturess, the annual savings of 49.99 degrees electricity consumption;

Moreover, the elimination of the traditional lighting stroboscopic phenomenon, for the primary and secondary school students vision protection is very good.

Their hearts there is a greater idea: According to statistics, there are a total of about 3.4 million classrooms, if all replaced with LED Led lighting fluorescent replacement fixturess, the national classroom lighting energy savings of about 24 billion degrees per year (equivalent to one Large-scale thermal power plant one year power generation); reduce the consumption of about 100 million tons of standard coal; reduce CO2 emissions of about 2.3 million tons; saving electricity about 1.6 billion.

According to the experimental results, the Environmental Protection Agency experimental group to write “on the use of LED lighting classroom lighting energy saving and environmental effects of the experimental study” reflects the contemporary juvenile thinking and the courage to create the spirit, as well as students for energy saving and environmental protection aspects Beneficial exploration and bold practice.

energy saving led light fluorescent creation of environmental protection

Now, led by Hou Kai Ying experimental group first suggested to the Yaohua school, in the future, the upgrading of the classroom, give priority to the replacement of LED Led lighting fluorescent replacement fixtures, which can not only energy saving, but also can effectively reduce the operating costs of the school, you can also use energy-saving facilities To the school students to promote the concept of energy saving and environmental protection is a combination of energy saving, economic and educational significance of the work. They also want to recommend to the national school, consider the classroom lighting as soon as possible to replace the LED Led lighting fluorescent replacement fixtures.

Sunshine youth comprehensive development

As the experimental group’s sponsors and organizers, this year’s 14-year-old Houkai Ying can achieve the results now is not accidental. His curiosity, a wide range of hobbies. He likes to read and read a wide range, like reading science, history, biographies and other books, and often with their parents to discuss political, historical, scientific and other issues.

In addition to reading, he also likes to study the living habits of animals, keeping silkworms, fish and other small animals, and observe, record and study their habits, especially for all kinds of ants living habits, living environment and nest structure in-depth study , Has designed its own nest, successfully cultivated from the ant colony ant.

In an interview with the author, Houkai Ying smiled and said: “The idea is very simple to do this, we Yaohua Environmental Protection Society’s idea is ‘environmental protection from the side to start, from now on environmental protection’, so I and my The students wanted to combine the daily life to do some environmental research and research, on the one hand to do some contribution to environmental protection, on the other hand can exercise our own ability.

“Although the strength and ability of a student is limited, but through our study, we also want to whole society initiative, hope everyone, each unit can invest more energy and environmental protection concerns and enthusiasm.Through common Efforts to make the water cleaner, more bluer sky, so that the earth home better! “Hou Kai Ying said.
