What are the national standards for classroom lighting eye protection lamps? Mainly these six points!

2021-10-28

Nowadays, the myopia rate of primary and secondary school students remains high. More and more people propose to pay attention to the improvement of students' eyesight and classroom health lighting, especially students' parents. Relevant departments have issued relevant specifications, such as hygienic specifications for lighting and lighting in primary and secondary school classrooms, work plan for myopia prevention and control of primary and secondary school students, hygienic specifications for lighting and lighting in primary and secondary school classrooms, etc.

So what are the national standards for classroom lighting eye protection lamps? There are six main standards: excellent illumination, no glare, high color rendering index, no stroboscopic damage, moderate color temperature and no blue light damage.

1、 Excellent illumination

It is pointed out in the hygienic code for daylighting and lighting of classrooms in primary and secondary schools that all classrooms should be equipped with classroom eye protection lamps, and the uniform illumination value on the classroom table should not be less than 300lx, and the illumination uniformity should not be less than 0.7; The classroom blackboard shall be equipped with classroom blackboard lamp, which shall maintain a uniform illumination value of not less than 500lx, and the illumination uniformity shall not be less than 0.8.

Fluorescent lamps are selected as the lighting fixtures in the classroom. The uniform illumination of the class desktop and blackboard is lack of 200lx, and there is no special lighting on the blackboard. During self-study at night, the lack of illumination is very significant, which simply leads to students learning too close to the desktop. When reading the words on the blackboard, their eyes will narrow unconsciously, especially the students in the back row. Then bring eye fatigue and cause myopia.

2、 No glare

It is pointed out in the hygienic code for daylighting and lighting of classrooms in primary and secondary schools that the unified glare value (urg) of classrooms should not be greater than 19. Most fluorescent lamps used in classroom lighting have severe problems of glare, which can easily lead to students' myopia, lax students' attention and affect their learning power.

3、 High color rendering index

It is pointed out in the hygienic code for daylighting and lighting of classrooms in primary and secondary school parks that the color rendering index of classroom lighting sources should not be less than 80. The color rendering index of traditional fluorescent lamps and LED lamps without glare treatment is about 70, and the picture will be distorted if the color rendering index is less than 80.

4、 No stroboscopic damage

Stroboscopic has the most significant impact on vision. It is very easy to distract students' attention and reduce learning power. The stroboscopic phenomenon of traditional fluorescent lamps is particularly serious when starting and voltage is unstable. Learning in this environment for a long time is also a simple cause of visual fatigue.

5、 Moderate color and temperature

It is pointed out in the hygienic code for daylighting and lighting of classrooms in primary and middle schools that the classroom should choose the light source with 3300k-5500k color temperature. The color temperature of professional LED classroom eye protection lamps is basically 5000K, which belongs to warm white light. In many campuses, the color temperature of traditional fluorescent lamps is greater than 6500k, which is attributed to cold white light.

6、 No blue light damage

The word "Blu ray" is not unfamiliar to everyone. General LED lamps do not pass the anti blue light treatment, but they are damaged. Professional LED classroom eye protection lamps have passed professional treatment and reached the exemption level without blue light damage.

Eye protection lamps for educational lighting meeting these six points can effectively reduce the myopia rate of students. 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, etc.) choose "Huahui lighting"!

As a promoter of Campus Lighting health, Huahui lighting is the first batch of qualified units for high-quality lighting environment in classrooms in South China. It is also the "top ten educational lighting brands" in China's lighting industry in 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to children's visual health!

Huahui lighting has designed special lighting fixtures for classroom - led eye protection classroom lamp and led eye protection blackboard lamp, which meet the national standard. The average (constant) illuminance of the desk is greater than 300lx and the illuminance uniformity 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 lighting aiot intelligent education lighting overall solution. Through the self-developed intelligent lighting products, equipped with self-developed intelligent boxes (such as intelligent distribution box or intelligent air switch), the lighting mode that meets the needs of teaching can be easily switched by using 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!
