In recent years, the nearsightedness of students is widespread and has even become one of the main health problems affecting young people. The General Office of the National Health and Family Planning Commission, the General Office of the Ministry of Education and the National Health Office for Women and Children issued the Guiding Opinions on Strengthening the Prevention and Control of Myopia in children and Adolescents on October 19, 2016. The "Opinions" put forward the implementation of scientific education and create a good eye environment guidance. The aim is to effectively control the incidence of myopia in children and adolescents. According to the document, all primary and secondary schools should ensure that all teaching facilities and conditions (lighting and lighting in classrooms and dormitories, desks and chairs, blackboards, etc.) comply with relevant national documents and standards in accordance with the requirements of the prevention and control work Plan, and provide students with a learning environment that meets the requirements of eye hygiene.

At present, the use of fluorescent lamps in domestic primary and secondary school classrooms is generally low lighting, serious light failure, illuminance and illuminance uniformity can not reach the national standards, and even direct exposure to students' eyes, resulting in dazzling phenomenon in students' eyes, fluorescent lamp installation of inductor ballast generally has serious light strobe phenomenon, a long time will inevitably cause visual fatigue leading to myopia. And fluorescent lamps contain mercury, which will pollute the environment.

In contrast, LED lights can completely avoid the above problems, and has the characteristics of energy saving and environmental protection, beautiful appearance, eye protection, power saving, long life, safer, low maintenance costs. Specifically, it is as follows:

1. The appearance is simple and the classroom is matched with a more simple, clean and bright space, and the lighting material is selected with high-quality materials, high-quality reflective materials, and the reflective rate reaches 85%;

2. Advanced diffuse reflection material and design based on optical principle, so that the light is soft and bright, the beam distribution is uniform, so that there is no dark corner in the classroom;

3. Good power saving effect, power saving up to 60%, power density up to 8.5w/ square meter, reduce school lighting pressure;

4. Blue light hazard is exempt level, which fully protects students' eyes from the negative effects of long-term light;

5.LED lights are high voltage resistant to ensure the safety of the entire school power system.
