Er det kostnadseffektivt-for skolebelysning å erstatte LED-lamper for undervisningsbelysning jevnt?
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.
Lysmiljøet på en skole må oppgraderes, og de tradisjonelle T8-lysrørene erstattes med LED-lamper for undervisningsbelysning. Dette er bestemt til å bli en stor utgift. Lederne for mange skoler med ikke så sterk økonomi har begynt å vurdere det. For å møte belysningsstandardene til utdanningsbransjen, er det kostnadseffektivt-for skolebelysning å erstatte LED-lamper for undervisningsbelysning på ensartet måte?
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 langsiktig{{0}}perspektiv er det faktisk ganske kostnadseffektivt-å oppgradere campusbelysning. Selve undersøkelsen viser at strømforbruket til pedagogisk belysning LED-lamper er mye mindre enn for tradisjonelle T8-lysrør. Vi lærte av Venucia at 30W pedagogisk belysning LED klasseromslys kan erstatte 80W tradisjonelle T8 lysrør, og 40W pedagogisk belysning LED tavlelys kan erstatte 80W tradisjonelle T8 fluorescerende lys. 80W fluorescerende lamper er ofte brukte lamper i klasserom tidligere. En lampe inneholder to lysstoffrør, ett lysstoffrør bruker 36W, og den matchende forkoblingen bruker 4W. Fra dette kan de energibesparende{12}fordelene ved LED-lamper for undervisningsbelysning beregnes. Basert på 50 klasserom i en ungdomsskole, hvert klasserom har 9 klasseromslys, 2 tavlelys, og lysene er tent 10 timer i døgnet kan det beregnes at det daglige strømforbruket til ett klasserom før oppussingen er 7,2 kWh , og det daglige strømforbruket til ett klasserom etter oppussingen er 7,2 kWh. Strømforbruket er 3,5 kWh, så de pedagogiske belysnings-LED-lampene kan spare 5,3 kWh strøm om dagen, og energibesparelsen når 151 prosent. Det kan også konkluderes med at elektrisiteten som en skole sparer på en dag er 265 kWh, og strømmen som en skole sparer i løpet av et år (beregnet ut fra 250 skoledager) er 66 250 kWh. Hvis strømkostnaden er 0,88 yuan per grad, vil den være 58 300 yuan på ett 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.
