What is the standard of classroom lighting that can help prevent and control myopia?


Education is a great project of talent strategy, and the classroom is the main place for students to study. Classroom lighting "has been used for a long time and myopia caused by poor lighting environment" has gradually become the focus of attention.

According to statistics, students spend at least 8 hours a day in the classroom, while closed management schools may be as high as more than a dozen hours. Therefore, classroom lighting needs to be much stricter than living lighting. We should fully consider the brightness required for writing, reading and class. At this stage, there are still many school classroom lighting equipment aging, low illumination and glare, which are one of the important reasons for the decline of vision and the formation of myopia. Therefore, a classroom lighting in line with national standards is one of the effective ways to take care of students' eyesight.

How to effectively improve children's classroom lighting environment? The most direct and effective way is to replace lamps that meet national standards, including LED eye protection classroom lamp and led eye protection blackboard lamp.

During the transformation of classroom lighting, often due to lack of understanding of lighting indicators and lighting technology, the transformation is generally realized by replacing high-power fluorescent tubes or using ordinary LED lamps to replace the original fluorescent lamps. However, Huahui education lighting senior R & D Engineer pointed out that simple and rough transformation can not achieve the effect of myopia prevention and control.

Therefore, the classroom lighting transformation standard of eye protection and myopia prevention and control generally recommends 9 + 3 mode, and needs professional lighting design: that is, three LED eye protection blackboard lights to ensure that the blackboard maintains an average illuminance ≥ 500lx and illuminance uniformity ≥ 0.8; There are also 9 LED eye protection classroom lights to ensure that the average illumination of the classroom desktop is > 300lx, the uniformity of illumination is ≥ 0.8, and the glare UGR is ≤ 16; Color temperature 5000K, blue light rg0, stroboscopic no harm, color rendering index ≥ 90.

Design a classroom lighting that can protect eyes and help prevent myopia. It is recommended that all primary and secondary schools and institutions (including public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, educational institutions), classroom lamp OEM and OEM choose the brand of "Huahui lighting"!

As a promoter of Campus Lighting health, Huahui lighting has been deeply engaged in the lighting industry for 26 years. It is the first batch of qualified units for classroom high-quality lighting environment in South China. It is also the "top ten educational lighting brands" in China's lighting industry in 2021. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to students' visual health.

Huahui lighting is specially used for classroom lighting lamps - led eye protection classroom lamp and led eye protection blackboard lamp, which meet the national standard. The average (constant) illumination of the desk is greater than 300lx and the uniformity of illumination is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the illumination uniformity is 0.8; The color rendering index is greater than 90, and the color reduction is high; The grid anti glare design is adopted, and the glare value is less than 16, which is not dazzling; The color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.

The use of Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be combined with Huahui education lighting aiot intelligent education lighting overall solution. Through the independently developed intelligent lighting products, equipped with the independently developed intelligent box (such as intelligent distribution box or intelligent air switch), the lighting mode meeting the needs of teaching can be easily switched by using the intelligent full touch screen scene switch, remote control or mobile phone app, Realize the intelligent requirements of constant illumination, one key scene control, curtain linkage, ultraviolet sterilization and so on!
