The general classroom area of the school is generally 50-60 square meters. According to national regulations: for standardized schools, the area of each classroom needs to be no less than 54 square meters. Conditional schools should also set up students' personal belongings cabinets in the classroom. Of course, there will be great differences due to different school areas and areas.

In Huahui, the staff investigated and visited some old classrooms, covering an area of about 60 square meters. Some classrooms are equipped with 8 fluorescent lamps, some with 8 fluorescent lamps, and some with 12 fluorescent lamps. The installation positions have not been professionally planned, and the installation directions are also different, and some are parallel to the blackboard. Another problem is that because of the long years of fluorescent lamps, some are not on, some are flickering, both ends of the lamp become black, and the lamp consumes a lot of power.

Nine led eye protection classroom lamps developed and produced by Huahui education lighting are used in the classroom area to realize the uniform lighting of ordinary classrooms. The eye protection lamp has the characteristics of no stroboscopic, no blue light, no glare, etc. It adopts full-spectrum light source, which is close to natural light. The light environment of the whole classroom is comfortable and conducive to students' learning.

Three LED eye protection blackboard lamps developed and produced by Huahui education lighting are installed in the blackboard area. By adjusting the irradiation angle of the blackboard lamp, the blackboard lighting is uniform, which is conducive to students to see the words on the blackboard. Therefore, the configuration of "9 + 3" can meet the requirements of national educational lighting standards, reduce energy consumption and save school costs.

According to the classroom lighting design of "9 + 3" mode in line with the national standard, 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 the brand of "Huahui lighting"!
