Er det omkostningseffektivt-for skolebelysning ensartet at erstatte LED-lamper til undervisningsbelysning?
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.
Belysningsmiljøet på en skole skal opgraderes, og de traditionelle T8-lysstofrør udskiftes med pædagogiske belysnings-LED-lamper. Dette er bestemt til at blive en stor udgift. Lederne af mange skoler med ikke så stærk økonomi er begyndt at overveje det. For at opfylde belysningsstandarderne for uddannelsesindustrien, er det omkostningseffektivt-for skolebelysning ensartet at erstatte LED-lamper til undervisningsbelysning?
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.
Fra et langsigtet{{0}}perspektiv er det faktisk ret omkostningseffektivt-at opgradere campusbelysningen. Selve undersøgelsen viser, at elforbruget for pædagogiske belysnings LED-lamper er meget mindre end traditionelle T8-lysstofrør. Vi lærte af Venucia, at 30W pædagogisk belysning LED klasseværelseslys kan erstatte 80W traditionelle T8 fluorescerende lys, og 40W pædagogisk belysning LED tavlelys kan erstatte 80W traditionelle T8 fluorescerende lys. 80W fluorescerende lamper er tidligere almindeligt anvendte lamper i klasseværelser. En lampe indeholder to lysstofrør, et lysstofrør forbruger 36W, og den matchende forkobling bruger 4W. Ud fra dette kan de energibesparende{12}}fordele ved LED-lamper til undervisningsbelysning beregnes. Med udgangspunkt i 50 klasseværelser i en mellemskole, har hvert klasseværelse 9 klasseværelseslys, 2 tavlelys, og lysene er tændt 10 timer dagligt, kan det beregnes at det daglige strømforbrug i et klasseværelse før renoveringen er 7,2 kWh , og det daglige strømforbrug i et klasseværelse efter renoveringen er 7,2 kWh. Strømforbruget er 3,5 kWh, så de pædagogiske belysnings-LED-lamper kan spare 5,3 kWh strøm om dagen, og energibesparelsen når op på 151 procent. Det kan også konkluderes, at den strøm, en skole sparer på én dag, er 265 kWh, og den strøm, en skole sparer på et år (beregnet ud fra 250 dages undervisning) er 66.250 kWh. Hvis elprisen er 0,88 yuan pr. grad, vil det være 58.300 yuan på et år.
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.
