Is it cost-effective for school lighting to uniformly replace educational lighting LED lamps?
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.
The lighting environment of a school needs to be upgraded, and the traditional T8 fluorescent lamps are replaced with educational lighting LED lamps. This is destined to be a huge expense. The leaders of many schools with not so strong economy have begun to consider it. In order to meet the lighting standards of the education industry , Is it cost-effective for school lighting to uniformly replace educational lighting LED lamps?
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.
From a long-term perspective, it is actually quite cost-effective to upgrade campus lighting. The actual survey shows that the electricity consumption of educational lighting LED lamps is much less than that of traditional T8 fluorescent lamps. We learned from Venucia that 30W educational lighting LED classroom lights can replace 80W traditional T8 fluorescent lights, and 40W educational lighting LED blackboard lights can replace 80W traditional T8 fluorescent lights. 80W fluorescent lamps are commonly used lamps in classrooms in the past. One lamp contains two fluorescent tubes, one fluorescent tube consumes 36W, and the matching ballast consumes 4W. From this, the energy-saving benefits of educational lighting LED lamps can be calculated. Based on 50 classrooms in a middle school, each classroom has 9 classroom lights, 2 blackboard lights, and the lights are turned on for 10 hours a day, it can be calculated that the daily power consumption of one classroom before the renovation is 7.2 kWh, and the daily power consumption of one classroom after the renovation is 7.2 kWh. The power consumption is 3.5 kWh, so the educational lighting LED lamps can save 5.3 kWh of electricity a day, and the energy saving reaches 151%. It can also be concluded that the electricity saved by a school in one day is 265 kWh, and the electricity saved by a school in a year (calculated based on 250 days of class) is 66,250 kWh. If the electricity cost is 0.88 yuan per degree, then it will be 58,300 yuan in one year.
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.
