"Centennial plan, education-oriented", education is a stage that we must go through when children grow up. From the age of 6-7, we will step into the school, learn advanced cultural knowledge, and learn the truth of life. We can't walk out of the campus and enter the society until we are in our 20s. It can be said that our entire teenage years were spent in school, and in a way the school is our second home.
With the development of the times, kindergartens and art schools account for an increasing proportion in our lives. The two have one thing in common, that is, the classrooms are beautiful and generous, and they can capture the hearts of students and parents at a glance. However, with the continuous development of artistic lighting, there are more and more problems in the field of artistic lighting. The lighting effect is not up to standard. The students are gradually nearsighted, and there is a big hidden danger in visual health.
What are the standards that classroom lighting needs to comply with?
(1) The illuminance of the desk and blackboard should meet the standard
① The average illuminance value on the classroom desk should not be less than 300lx, and the illuminance uniformity should not be less than 0.7;
②The classroom blackboard should be equipped with local lighting, which should maintain an average illuminance value of not less than 500lx and an illuminance uniformity of not less than 0.8. In order to pursue retro and high pressure, some art schools lower their deliberate brightness, and they will not reach the standard if they are not careful.
(2) No glare on the desktop and blackboard
The uniform glare value (URG) of classroom lighting should not be greater than 19. The special effects of some art schools for the glorious glass will also cause the glare value of individual desks to exceed the standard.
(3) High color rendering index of classroom lighting
The color rendering index of classroom lighting sources should not be less than 80. Some kindergarten classrooms like colored lights, which causes objects distorted by such lights to be seriously distorted.
(4) The color temperature of the classroom lighting source is moderate
Classroom lighting should use 3300K-5500K color temperature light source. Some art schools choose yellowish lights in order to make the classroom look more elegant. The color temperature of light sources that are too yellowish is difficult to reach 3300K.
