Kādas ir problēmas ar skolas klases apgaismojumu?
Students spend most of their time studying in the classroom. If the classroom lighting is not well designed, it is easy to cause visual fatigue. After a long time, it will lead to the decline of students' eyesight and academic performance. Therefore, we must pay attention to the renovation of classroom lighting facilities. So what are the problems with the lighting facilities in the school classrooms, and how should they be solved? Let's take a look with the teaching office lamp manufacturers now!
1. Many school classroom lighting lamps are placed in an unreasonable direction, resulting in glare. The lighting fixtures in school classrooms are generally in the direction of the level and the blackboard, which makes it easy for the light to directly enter people's eyes. When there is excessive brightness or excessive brightness contrast in the field of vision, students will feel dazzling and affect their vision. This dazzling light is glare. Glare is divided into direct glare, reflected glare and contrast glare. The visual effect of glare reduces the visual effect of the work area, causing visual discomfort and distraction, easily causing visual fatigue and damage to eyesight.
Solution: The arrangement of the lamps should be parallel to the long axis and the students' desks, and perpendicular to the blackboard, so that the light of the lamps will enter people's eyes from both sides of the eyes, avoiding direct sunlight; at the same time, put the lamps It is arranged above the vertical blackboard channel, so that the desktop forms side or two sides lighting, and the lighting effect is better.
2. Gaismas avotu skaits skolas klašu apgaismojumam ir nepietiekams, kā rezultātā veidojas ēnas. Nepietiekams gaismas avotu skaits ir arī projekcijas cēlonis. Nelielā lampu skaita dēļ attālums starp lampām ir pārāk liels. Kad skolēns sēž starp diviem lukturiem un atrodas tuvu pēdējam lukturim, pirmās lampas apgaismojums nevar izstarot otrās lampas pozīciju. Tas nevar efektīvi kompensēt ēnas, ko rada lampa, kas spīd uz cilvēka ķermeni.
Solution: Because we can't use shadowless lamps like the operating room, we can appropriately increase the number of lamps and change the installation position of the lamps. In places where the light sources are denser, we can appropriately reduce the light intensity and use more low-power lamps. , replacing less high-power lamps.
3. Gaismas avots nav fiksēts. Kad ventilators ir ieslēgts, gaismas avots būs nestabils. Skolas klases augstā augstuma dēļ, lai novērstu gaismas ietekmi uz vidusskolas telpu, skola izmanto lustru, lai lampu pakarinātu vidējā-gaisā noteiktā augstumā no darbvirsmas, un dažos skolas klases apgaismojumā tiek izmantota mīksta piekārta, tas ir, ja gaismas avots nav fiksēts, kad vasarā ir karsts laiks un ir ieslēgts ventilators, lampa turpinās šūpoties uz priekšu un atpakaļ, padarot gaismas avotu nestabilu un ietekmējot. spilgtumu. Tajā pašā laikā lampas korpuss turpina trīcēt, kas palielina bīstamību.
Risinājums: piestipriniet mīksto lustru un izmantojiet materiālu ar lielāku cietību, lai nostiprinātu gaismu.
