School classroom is related to adolescent eyesight health, any school is committed to provide more comfortable school environment for adolescents, build conform to the specifications for design of small and medium-sized school and kindergarten classroom standard school classrooms.
But the school classroom is not necessarily equal to use the lamps and lanterns of expensive, want to do school classroom really well is not easy.
So what is the key school classroom?
First is the idea.
Determined to build high quality school classroom environment, classroom environment, determined to build high quality school to surmount every difficulty to create high quality school classroom environment.
The mind is the precursor of action, cannot leave who have decided to the success of any one thing.
So the key to the school classroom, completes the school the idea of the classroom.
Through the myopia prevention and control of education, there are a lot of long-term meticulous work to be done, not only with good light, also need to put the light with good, lets the student have a better visual light environment.
Children of all kinds of physiological barrier is not yet mature, the body is sensitive to light environment of harmful factors than adults, light environment is also higher, therefore, the classroom light environment must conform to the technical indexes of child and adolescent safety standard.
So ensure that the hardware construction of the school classroom is also essential.
At the same time, completes the school classroom, the school system with eye health education should be strengthened, prevent children myopia on appropriate technology, activities, strengthen the vision care.
How to transform the classroom: 1.
Intensity of illumination and the intensity of illumination evenness optimal: national standard GB7798 -
2010 rules, the classroom desk surface maintain plane illumination 300 or higher, intensity of illumination evenness 0 or higher.
7, to maintain the blackboard 500 or higher, the average illuminance on the intensity of illumination evenness 0 or higher.
8.
By the end of 2018, we have modified all 10000 primary and middle school classroom lights, more than 90% of the intensity of illumination and uniformity can not meet the national standard requirements.
Some schools even desktop and blackboard is only more than 100 lux, students learning for a long time in such a light environment, easy to cause eye fatigue, that cause myopia.
2.
Anti glare: gb regulation, the classroom
led lighting glare value & lt;
19, while most of the school classroom led lighting using simple fluorescent stents, the light source directly exposed, the light is very dazzling, glare value more than 22.
So that the eye muscles too nervous, the serious influence students' concentration in class.
3.
And blue light, and other harmful light: common LED light source of high frequency short wave - 400
Between 500 nm blue light, arrive to directly penetrate eye fundus macular ward, cause irreversible damage to the eyes, such as the formation of myopia.
The traditional led besides blue light damage, heat and uv, near ultraviolet, photochemical retinal, weak stimulation, small light source, infrared radiation of seven kinds of harmful light.
The 7 kinds of harmful light in different extent, serious harm to our eyes and body.
4.
Droop, prolong service life, lamps and lanterns of normal use after six months would be a serious light attenuation, cause the luminous flux decreases, which can not meet the national standards for, the brightness of the current in order to maintain standards, thus replacing the cycle for 2 to 6 months of lamps and lanterns, and need relevant maintenance personnel long-term maintenance, high maintenance cost and resource waste.
5.
Color rendering index optimization: ordinary fluorescent spectrum is not complete, resulting in lack of color and color.
Far less than the national standard Ra 80 or higher, and the colour of lamps and lanterns reduction ability is bad, will directly affect a child's color vision.
6.
Color temperature comfortable: national standard regulations, color temperature is 3300 -
5300 k, and the actual measurement results reached 6500 k color temperature is too high will lead to rising rates of radiation, blue blue also will increase, the blue light will increase due to genetic, environmental nutrition, health habits and old age related macular degeneration.
Night lessons for a period of time off will affect the students in melatonin secretion, reduce the sleep quality and influence on the second day of learning efficiency.
