Nowadays, an indisputable fact is that the proportion of myopia in children is getting higher and higher, and parents are more and more worried about their children's various vision problems. As the only country in the world that implements eye exercises, the rate of myopia among young people is at the forefront! When many parents find that their children have vision problems, the first thing that comes to mind is playing games on mobile phones, or reading a book. In fact, the illuminance of the desktop and the illuminance of the blackboard are also closely related to the child's eyesight. In order to curb the rise in the rate of myopia, the education industry jointly issued the "Guiding Opinions on Strengthening the Prevention and Control of Myopia in Children and Adolescents", emphasizing that: all primary and secondary schools should ensure various teaching facilities and conditions in accordance with the requirements of the "Prevention and Control Work Plan" ( The lighting and lighting of classrooms and dormitories comply with relevant national documents and standards, and provide students with a learning environment that meets the requirements of eye hygiene. For new schools, acceptance standards must be set according to national standards during construction and design.
Reikia atnaujinti mokyklos apšvietimo aplinką, o tradicines liuminescencines lempas T8 keičia edukacinio apšvietimo LED lempos. Tai lemta didžiulėms išlaidoms. Daugelio ne tokios stiprios ekonomikos mokyklų vadovai ėmė svarstyti. Kad atitiktų švietimo pramonės apšvietimo standartus, ar naudinga{1}}mokyklų apšvietimui vienodai pakeisti švietimo apšvietimo LED lempas?
To be honest, it is necessary for the lighting of a school to meet the educational lighting standards, sooner or later. "A strong youth makes the country stronger, and a healthy youth makes the nation prosperous." Providing a beautiful light environment for children is a significant feat.
Žvelgiant iš ilgalaikės{{0}}perspektyvos, iš tikrųjų yra gana ekonomiškai-naudinga atnaujinti universiteto apšvietimą. Tikroji apklausa rodo, kad mokomojo apšvietimo LED lempos sunaudoja daug mažiau elektros nei tradicinės T8 liuminescencinės lempos. Iš „Venucia“ sužinojome, kad 30 W mokomojo apšvietimo LED klasės šviestuvai gali pakeisti 80 W tradicinius T8 liuminescencinius šviestuvus, o 40 W mokomojo apšvietimo LED lentos šviestuvai gali pakeisti 80 W tradicinius T8 liuminescencinius šviestuvus. 80 W liuminescencinės lempos anksčiau buvo dažniausiai naudojamos klasėse. Vienoje lempoje yra dvi fluorescencinės lempos, viena fluorescencinė lempa suvartoja 36 W, o atitinkamas balastas – 4 W. Iš to galima apskaičiuoti mokomojo apšvietimo LED lempų energijos taupymo naudą. Remiantis 50 klasių vidurinėje mokykloje, kiekvienoje klasėje yra 9 klasės šviestuvai, 2 lentos šviestuvai, o šviesa įjungiama 10 valandų per dieną, galima skaičiuoti, kad vienos klasės elektros energijos suvartojimas prieš renovaciją yra 7,2 kWh. , o vienos klasės elektros energijos suvartojimas parai po remonto yra 7,2 kWh. Energijos suvartojimas yra 3,5 kWh, todėl edukacinio apšvietimo LED lempos per dieną gali sutaupyti 5,3 kWh elektros energijos, o energijos taupymas siekia 151 proc. Taip pat galima daryti išvadą, kad per vieną dieną mokyklos sutaupyta elektros energija yra 265 kWh, o per metus (skaičiuojant pagal 250 pamokų dienų) – 66 250 kWh. Jei elektros kaina yra 0,88 juanių vienam laipsniui, tai per vienerius metus bus 58 300 juanių.
After the school lighting fixtures are replaced with educational lighting LED fixtures, in addition to the economic effects brought by energy saving and power saving, it can also bring huge economic effects in terms of maintenance. According to statistics from Qichen Industrial, the maintenance cost of a fluorescent tube lamp is about 158 yuan for one year, including the replacement of lamp tube, ballast, starter and labor costs. Usually, there are 11 fluorescent lamps in a classroom, and each lamp has two lamp houses, that is, 22 lamps, so the maintenance cost of one classroom lamp tube is 3476 yuan, and the maintenance cost of 50 classroom lamp tubes is 173800 yuan. Yuan. According to the 8-year service life of a set of traditional lighting fluorescent lamps, the maintenance cost of this school's lighting lamps is as high as 1,390,400 yuan. The educational lighting LED lamps have a service life of up to 50,000 hours, and are basically maintenance-free within 8 years. Therefore, the economic effect brought by the educational lighting transformation is quite considerable, and it can save the school about 1,856,800 yuan in 8 years.
If the school's educational lighting is also equipped with a smart campus lighting system, secondary energy saving can be achieved. The smart campus lighting system can realize intelligent management and control: class mode, projection mode, self-study mode, activity mode, cloudy supplementary light mode, constant illumination mode, self-detection of classroom personnel activities, automatic shutdown of equipment when no one is present, to prevent power waste, All-round energy saving.
