According to the 2020 national survey on myopia among children and adolescents released by the National Health Commission, the overall myopia rate of children and adolescents in China is 52.7%, ranking first in the world, including 14.3% for children aged 6, 35.6% for primary school students, 71.1% for junior high school students, and 80.5% for senior high school students.
Some experts said that "although there are many causes of myopia, according to the investigation of the National Center for Disease Control and Prevention, poor classroom lighting environment is one of the main reasons for the decline of students' vision." In fact, China has formulated relevant regulations, which put forward mandatory requirements for the technical indicators such as the illuminance and uniformity of illuminance on the classroom desktop, the average illuminance and uniformity of illuminance on the classroom blackboard, the color temperature and display index of classroom lights, and the unified glare index of the classroom.
With the attention of relevant national policies, the transformation of classroom lighting is in full swing throughout the country. However, the lighting professionals of Huahui Education found that the lighting quality of some classrooms was not qualified even if the special lamps for the classroom were replaced.
The transformation of classroom lighting should not be understood as "replacing old lights with new ones", but as an overall solution to the light environment. This includes professional lighting design based on real space scenes and the needs of different people, photobiology theory, and the refinement of intelligent control.
In view of the existing problems in classroom lighting, Huahui Education Lighting implements the "9+3" eye protection lighting solution, namely, 9 sets of LED eye protection classroom lights+3 sets of LED eye protection blackboard lights. The classroom adopts 9 sets of LED eye protection classroom lights, which are arranged vertically on the blackboard, to fully meet the requirements of the standard light distribution direction and reduce the glare reflected by the blackboard. The blackboard adopts three sets of LED eye protection blackboard lights arranged parallel to the blackboard. The layout of the lights is reasonable and uniform, improving the uniformity of the classroom illumination, effectively preventing glare, and meeting the national standards for classroom lighting.
The transformation of classroom lighting has made the classroom lighting more soft. 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, and educational institutions), classroom lighting OEMs, and licensors choose the "Huahui Lighting" brand!
As a health promoter of campus lighting, Huahui Lighting has been deeply involved in the lighting industry for 27 years. It is one of the first units to reach the standard of high-quality lighting environment in classrooms in South China, and also one of the "top ten educational lighting brands" in China's lighting industry in 2021. It strictly controls the color temperature, glare, blue light, illuminance and other problems in educational lighting to avoid harmful effects of bad lighting on students' vision 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 that the average (constant) illuminance of desks is more than 300lx, and the illuminance uniformity is 0.7; The average (constant) illumination of the blackboard is 500lx, and the illumination uniformity is 0.8; The color rendering index is greater than 90, and the color reversibility is high; The grid anti glare design is adopted, and the glare value is less than 16 without 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 lights and LED eye protection blackboard lights can be matched with the overall solution of Huahui Education Lighting AIoT intelligent education lighting. Through the self-developed intelligent lighting products, the self-developed smart boxes (such as intelligent distribution boxes or intelligent air switches) can be loaded, and the intelligent full touch screen scene switch, remote controller or mobile phone APP can be used to easily switch the lighting mode that meets the teaching needs, so as to achieve constant illumination, one button scene control Intelligent demands such as curtain linkage and ultraviolet sterilization.
