Dobra zasnova osvetlitve učilnice mora izpolnjevati te standarde
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.
Dobra zasnova prenove razsvetljave učilnice mora izpolnjevati naslednje standarde:
1. V učilnice naj bo nameščena umetna razsvetljava.
2. Povprečna vrednost osvetljenosti, ki se ohranja na namizju učilnice, ne sme biti nižja od 300lx, enakomernost osvetlitve pa ne sme biti nižja od 0,7.
3. Učilnica mora biti opremljena z lokalno osvetlitvijo, povprečna osvetljenost ne sme biti manjša od 500lx, enakomernost osvetlitve pa ne sme biti manjša od 0,8.
4. V učilnici naj se uporablja svetlobni vir z barvno temperaturo 3300-5500K, indeks barvnega upodabljanja svetlobnega vira pa ne sme biti manjši od 80.
5. Enotna vrednost bleščanja (UGR) učilnice ne sme biti večja 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. Pri izračunu osvetljenosti pri načrtovanju razsvetljave se njen vzdrževalni učinek vzame kot 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.
Hkrati je treba prenoviti lokacijo učne razsvetljave v učilnici, da bi se izognili superpoziciji svetlobe v učilnici in pomanjkanju svetlobe slepih kotov, da bi dijakom resnično zagotovili zdravo, udobno in zeleno izobraževalno svetlobno okolje.
