What are the standards for classroom LED education lights to follow?
(1) Classroom and blackboard illumination should meet the standard
1 The average illuminance value on the desk of the classroom should not be lower than 300lx, and the uniformity of illumination should not be lower than 0.7;
2 Classroom blackboards shall be provided with local illumination lamps, which shall maintain an average illumination value of not less than 500 lx and an illumination uniformity of not less than 0.8. In order to pursue retro and high pressure, some art schools have reduced the brightness of their intentions.
(2) Classroom and blackboard surface without glare
The uniform glare value (URG) of classroom lighting should not be greater than 19. Some art schools are special effects for glazed glaze, which can 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 prefer colored lights, causing objects that are seen under such lights to be severely distorted.
(4) Classroom lighting source color temperature moderate
Classroom lighting should use a light source of 3300K-5500K color temperature. Some art schools choose yellowish lights in order to make the classroom look more elegant. The color temperature of a light source that is too yellowish is difficult to reach 3300K.
