Kakšne so težave z osvetlitvijo šolskih učilnic?
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. Število svetlobnih virov za razsvetljavo šolskih učilnic je premajhno, kar ima za posledico sence. Vzrok za projekcijo je tudi premajhno število svetlobnih virov. Zaradi majhnega števila svetilk je razdalja med svetilkami prevelika. Ko učenec sedi med obema svetilkama in je blizu druge svetilke, osvetlitev prve svetilke ne more sevati v položaj druge svetilke. Ne more učinkovito izravnati senc, ki jih povzroči svetilka, ki sije na človeško telo.
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. Vir svetlobe ni fiksiran. Ko je ventilator vklopljen, bo vir svetlobe nestabilen. Zaradi visoke višine šolske učilnice, da šola ne bi vplivala na svetlobo v višji učilnici, šola uporablja lestenec za obešanje svetilke v zrak-na določeno višino od namizja, in nekatera razsvetljava v šolskih učilnicah uporablja mehko visečo, to je, če vir svetlobe ni pritrjen, ko je poleti vroče in je ventilator vklopljen, se bo svetilka še naprej nihala naprej in nazaj, zaradi česar bo vir svetlobe nestabilen in vplival svetlost. Hkrati se telo svetilke nenehno trese, kar povečuje nevarnost.
Rešitev: Popravite mehki lestenec in za pritrditev luči uporabite material z večjo trdoto.
