What standard should a good eye protection classroom light meet
Speaking of light, it always reminds people of hope and light. However, the "world in our eyes" is becoming more and more blurred, and many people have to see the scenery through a thick layer of lenses. And this situation continues to spread, and presents a trend of generalization and younger age. At present, there are 600 million myopia patients in China, and the rate of adolescents is high. There are currently more than 200 million students in primary and secondary schools across the country, but many of the classroom lighting environments are not up to standard!
One, the illuminance and uniformity of illuminance of blackboards and desks are generally lower than national standards.
Second, most classroom blackboards are directly installed with exposed fluorescent tubes. When students are watching the blackboard, they are affected by the direct glare of the tubes, making it difficult to concentrate, reducing learning efficiency, and prone to visual fatigue, which can easily lead to myopia in the long term.
Three, fluorescent lamps are generally equipped with inductive ballasts, which have a serious stroboscopic effect, and excessive frequent adjustment of the student's visual system is bound to cause visual fatigue.
Fourth, most classrooms generally use high color temperature (6500K) fluorescent tubes. Because the light color is too white and the blue light component is too high, it is easy to cause excitement, fatigue, and even insomnia.
Classroom lighting directly affects the eyesight of students, so we must be careful when choosing school classrooms to choose lights. It can meet the lighting requirements and protect the eyesight of students. When choosing lights, we should pay attention to the following points:
The qualification of the lamp should be considered: certificate, test report, etc. The LED eye-protecting classroom lights produced by Benwei Lighting have national compulsory CCC certification, CQC energy-saving product certification, CE, CB certification, ISO9001; 2008 certification, ISO14001:2004 certification, and China energy-saving product certification.
Is the lamp special: In order to enhance the adhesion of users, many businesses will launch special lamps. The price of this lamp is definitely higher than that of general-purpose lamps. Of course, this is not the decisive factor for the quality of the lamp. It is up to the user to choose it or not. In order to develop LED classroom lighting fixtures that are truly eye-protecting, Benwei Lighting, from the perspective of human factors engineering, researches and develops healthy, comfortable, environmentally friendly, and energy-saving classroom lighting products from the perspective of visual health and human comfort. .
The light of the eye protection lamp needs to be studied carefully. It mainly depends on three aspects: firstly, the color temperature-4000~5000K; secondly, the stability-staring at the lighted tube, there can be no light jitter, and no feeling Dazzling; three look at the uniformity-the overall brightness of the lamp is uniform, and there are no brighter or darker spots.
