What can we do about the problems with classroom lighting?

With the development of the times, our emphasis on education has gradually increased, and the nine-year compulsory education has been fully realized. With the increasing academic burden of students, myopia has become a problem that cannot be ignored. For students, we need to pay enough attention to classroom lighting as they learn!

The current general classroom lighting situation is that the illuminance and illuminance uniformity of classroom desks are generally lower than the national standard (national standard: desk illuminance greater than 300lx, illuminance uniformity greater than 0.7). However, if students are in low illumination for a long time, and the illumination received by different desks in the same classroom is not uniform, it will cause some students to struggle to read, read, and write, and it is easy to cause visual fatigue.

In addition, most classrooms use ordinary bracket lamps installed in front of the blackboard as blackboard lamps, and no special blackboard lamps are used, or even blackboard lighting is not arranged, resulting in a blackboard average illumination far lower than the national standard (national standard: blackboard illumination greater than 500lx, uniformity greater than 0.8), some students cannot read the text on the blackboard, which is easy to produce boredom, resulting in a decrease in learning efficiency.

Too low color rendering index is also a common drawback of classroom lighting. Most classrooms use lighting fixtures with a color rendering index of around 70 (national standard: the color rendering index of the light source should not be less than 80). Low color rendering index can easily cause color distortion, especially In classrooms with high requirements such as art, it will affect the correct judgment of the color of the object, so that the object cannot truly present its color, and over time, it will cause vision problems such as color blindness and color weakness.

In addition, most classrooms generally use high color temperature (6500K) lighting tubes (national standard: classrooms should use 3300-5500K color temperature light sources), which has blue light hazards, blue light will cause irreversible damage to the retina, and vision is greatly threatened. High color temperature can easily cause students to be excited and easily fatigued because the light color is too white. ---- Education lamp manufacturers
