Koje standarde treba da zadovolji dobar dizajn renoviranja rasvjete u učionici?
Od kada smo imali 6 godina do kada smo imali 20 plus, proteklih 10 godina smo proveli u kampusu. Neki moji prijatelji će možda ići na diplomske i doktorske studije. Danas nećemo proučavati ove posebne slučajeve, već samo period od osnovne škole do fakulteta. Škola je naš drugi dom više od 10 godina.
In the past 10 years, our eyesight will continue to be troubled by lights. It is likely that after 10 years of school life experience, we have evolved from a child to "myopia". Of course, this kind of change is something we don't want to see, but myopia does not change with our will. What we can do is to protect our eyes. What the school can do is to provide the most professional educational lighting fixtures, mainly including classroom lighting. and blackboard lighting in two parts.
For classroom lighting, we must choose the best lighting fixtures from the perspective of illuminance and uniformity. As for the requirements for blackboard lighting, we have all been students. In the past, people who were seated close to the side couldn't see the blackboard. That was because the blackboard light was not installed properly, or even there was no blackboard light, and there were reflections, so the blackboard lighting would also affect the students' eyesight.
Dobar dizajn renoviranja rasvjete učionice trebao bi zadovoljiti sljedeće standarde:
1. U učionicama treba postaviti vještačko osvjetljenje.
2. Prosječna vrijednost osvjetljenja koja se održava na radnoj površini učionice ne smije biti niža od 300lx, a ujednačenost osvjetljenja ne smije biti niža od 0,7.
3. Učionička tabla treba da bude opremljena lokalnom rasvjetom, prosječna osvijetljenost ne smije biti manja od 500lx, a ujednačenost osvjetljenja ne smije biti manja od 0,8.
4. U učionici treba koristiti izvor svjetlosti s temperaturom boje od 3300-5500K, a indeks prikaza boja izvora svjetlosti ne smije biti manji od 80.
5. Jedinstvena vrijednost odsjaja (UGR) učionice ne bi trebala biti veća od 19.
6. Under the condition of maintaining the average illuminance value of 300lx, the current value of classroom lighting power density should not be greater than 11W/㎡, and the target value should be 9W/㎡.
7. Prilikom izračunavanja osvjetljenja u dizajnu rasvjete, njegov učinak održavanja se uzima kao 0.8.
Therefore, in order to effectively avoid the impact of educational lighting on students' vision, schools should use professional eye-protecting LED educational lighting fixtures, and professional technicians should be responsible for the installation to ensure the indicators of classroom lights and blackboard lights in educational lighting. All can meet the qualified requirements, ensuring that the light environment of each classroom not only has sufficient illumination and excellent uniformity, but also minimizes glare, so that no direct light enters the eyes of students.
Istovremeno, potrebno je renovirati lokaciju obrazovne rasvjete u učionici kako bi se izbjegla superpozicija svjetla u učionici i nedostatak svjetla slijepih uglova, kako bi se učenicima zaista pružilo zdravo, udobno i zeleno obrazovno okruženje.
