With the high myopia rate in China, the attention of all walks of life and government departments to classroom lighting has been effectively improved in recent years. As a classroom lighting environment directly related to myopia, creating eye protection classroom lighting is an important measure for myopia prevention and control.

A survey shows that primary and secondary school students in our country spend about 60% of their time in the classroom every day. In the National Natural Science Foundation Project "Research on classroom health lighting based on photobiological effect", the experiment shows that school classroom lighting has a direct impact on students' learning efficiency and vision health.

Many school classrooms are still using fluorescent tubes and ordinary lamps, and the lamp layout is unreasonable, low illumination, not up to standard, the use of naked lights, light glare, light stroboscopic, color rendering index < 80, very dazzling, long time in this environment to learn, the eyes are easy to produce fatigue, attention, learning efficiency, eventually lead to myopia.

The State Administration of market supervision and administration and the National Standardization Administration approved and issued the hygienic requirements for lighting design and installation of ordinary classrooms in primary and secondary schools (GB / t36876-2018). In this new standard, the illumination of tabletop and blackboard surface and hygienic requirements for design and installation of ordinary classrooms in primary and secondary schools are specified in detail

1. Suspended grid lamps should be used, and the efficiency of lamps should not be lower than 60%.

2. The unified glare value (UGR) should not be greater than 19, and the calculation method of UGR should be carried out according to cie117.

3. The color temperature should be 3300K ~ 5500k, and the color rendering index should not be less than 80.

4. The average illumination of classroom desktop should not be less than 300lx, and the uniformity of illumination should not be less than 0.7; The average illuminance of the blackboard surface shall not be less than 500lx, and the illuminance uniformity shall not be less than 0.8.

5. The suspender installation method shall be adopted, and the lighting power density of the classroom shall not be higher than 11W / m2, and it shall be lower than 9W / m2 in conditional areas. The vertical distance (g) between the lamp and the desk shall not be less than 1700mm.

6. When calculating the illuminance in lighting design, the maintenance coefficient should be taken as 0.8.

Creating healthy classroom lighting is an innovative measure for myopia prevention and control. 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 "huahuizhaoming" brand to effectively prevent myopia!

As a school lighting health promoter, Huahui lighting is one of the first batch of high-quality classroom lighting units in South China. It is also one of the "top ten education lighting brands" in China's lighting industry in 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in education lighting, so as to avoid harmful lighting to students' eyesight health!

Huahui lighting has designed led eye protection classroom lamp and led eye protection blackboard lamp, which are specially used for classroom lighting. They meet the national standard. The average (constant) illumination of desks is greater than 300lx, and the illumination uniformity is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the uniformity of illumination is 0.8; The color rendering index is more than 90 and the color reduction is high; Grid anti glare design, glare value is less than 16, no glare; Color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.

Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be used together with Huahui lighting aiot intelligent education lighting overall solution. Through self-developed intelligent lighting products, equipped with self-developed intelligent box (such as intelligent power distribution box or intelligent air switch), intelligent full touch screen scene switch, remote control or mobile app can be used to easily switch the lighting mode that meets the needs of teaching, Realize the constant illumination of the whole classroom, one button scene control, curtain linkage, UV sterilization and other intelligent needs!
