How to protect the health of school lighting

When we were young, the lights in the classroom could only be "bright enough" and "not twinkling and flickering". We never thought that lights need to be "exquisite" and "required". Today, education continues to advance and technology continues to develop. Modern school lighting needs more than just lighting standards, and it should also pay attention to protecting vision, energy conservation, and environmental protection, so that we can really love our students’ vision and improve school lighting.

How school lighting is eye-catching gradually attracts attention

According to surveys, primary and secondary school students in China spend about 60% of their time in the classroom each day. In the National Natural Science Foundation of China's "Light-biological effects of classroom health lighting research," experiments show that school classroom lighting directly affects student learning efficiency and visual health. When the classroom lighting and lighting conditions are insufficient and the light is too dark, students will instinctively approach the book. As time passes, it will naturally cause changes in the eye's refractive system, resulting in myopia.

China's first white paper on the study of visual health, National Vision Health, shows that myopia has become China’s “national disease”: among people over 5 years of age, the proportion of nearsightedness is 35.16% to 39.21%, and there are 1 person for every 3 people. It is myopia. The total number of patients suffering from myopia is between 437 million and 487 million. The high level of adolescents’ myopia not only affects the contemporary, but also harms the health quality of future citizens. It will have a major impact on the country’s social, economic, and even security.

In recent years, the prevention and treatment of students' myopia has become more and more concerned by students, parents and the society. In 2007, the education department formulated the “Work Plan for Prevention and Control of Myopia among Primary and Secondary School Students.” The program proposed “intensify the investment, effectively improve classroom lighting and lighting, desk and chair configuration, blackboard lighting and other teaching conditions in primary and secondary schools, and actively coordinate the health The administrative department regularly supervises and monitors the health status of school teaching, and guarantees that the teaching facilities and conditions are in line with the requirements of the "National Basic Standard for School Sports Hygiene Conditions and Related Hygiene Standards, and establish a good visual environment for students."

The relevant departments found during the visit that the school has gradually realized the importance of school lighting influencing students’ eyesight, and started to carry out lighting renovation projects, upgraded the original lighting methods, and illuminated the classrooms, corridors, playgrounds, dormitories and canteens. Change to LED lighting. As a new type of green light source product, LED is the trend of future development. However, the national standard for the use of school LED lighting products is currently vacant, and there is no basis for schools to purchase and use. The lack of market standards, the increasingly serious and young age of myopia, has aroused widespread concern in society. Therefore, how to choose the classroom lighting that is conducive to students' use of eye health, and how to provide the logistical support for the school's healthy green light environment are issues that schools and education departments are currently considering.

Carry out research on the school's healthy lighting environment

In order to fully implement the spirit of the “13th Five-Year Plan”, we have a comprehensive understanding of the classroom lighting environment of the country’s schools and students’ vision, and effectively strengthened the protection of students’ vision. In 2016, the Education Department’s Education Equipment Research and Development Center and Xiamen Lidaxin Lighting Co., Ltd. The "School Lighting Environment Research Center" was established.

The "School Lighting Environment Research Center" is committed to the study of the school's healthy lighting environment. It is obliged to shoulder the task, to provide knowledge of the school's popular science classroom lighting, to provide professional lighting inspection and design services for schools, and to establish a good environment for teachers and students. The visual environment provides data support and reference opinions for the development of school lighting standards by relevant national authorities.

At present, the center has established the "School Health Classroom Lighting Standardization and Product Realization Study" as a research topic. We will conduct research on the lighting environment of school classrooms across the country, and conduct in-depth investigations and study of the school's lighting environment through on-site visits, seminars, questionnaires, on-site interviews, and data measurements. Based on a large amount of research data, with the aim of “protecting eyesight, energy saving and environmental protection, and excellent quality”, we will use a new generation of LED optoelectronic technology to develop dedicated lighting fixtures that are suitable for use in classrooms and chalkboards. The products will meet eye protection indicators. It is better than the parameters of the classroom and blackboard lights that are currently available on the market.

At the same time, the center will conduct popular science propaganda, training, and seminars in the country according to the needs of the project, so as to popularize the knowledge and importance of the lighting environment in the school classroom. In order to provide schools with a more intuitive experience of healthy light environment classrooms, schools will be selected from the schools that were previously investigated for lighting transformation, and the lighting indicators of the school classrooms before and after the renovation will be compared to ensure that they are better than the national standards. At the end, the research report on “School Health Classroom Lighting Standardization and Product Realization Research” was published.

Promote the construction of school lighting standardization

The center researches and arranges more than 20 provinces and cities nationwide to ensure the rigor and authenticity of the data. At present, the first station of research work in Fujian Xiamen has also officially started. At the symposium, the person-in-charge explained the background, significance, and importance of the investigation to the school-related personnel involved in the survey. And conduct field visits, in-depth understanding of each school's lighting status, face-to-face communication, collecting "first-hand" information. Classroom lighting data measurement, simultaneous development.

At the same time, the center will organize seminars throughout the country this year to exchange ideas and discuss the status quo of the school classroom lighting environment, the implementation of the standardization of the lighting environment in the health classrooms, and the sharing of experiences. It advocates paying attention to and attaching importance to the school's lighting renovation project, the science popularization and health light environmental standards, and how to jointly promote school lighting standardization construction with the efforts of the whole society.

At present, LED lighting fixtures on the market are uneven, and some products that advertise energy-saving are at the expense of students' vision health. In view of this situation, the "School Lighting Environment Center" will carry out the research and development of full eye protection lighting work to protect students' eyesight, and comprehensively upgrade and optimize the six core parameters such as illumination, glare, strobe light, color rendering index, color temperature and blue light. And further consider how to scientifically and rationally arrange the installation location of lamps and lanterns, and effectively solve problems such as uneven uniformity of school classroom illumination and hazards of glare. It also provides data support and reference opinions for the follow-up countries in the development of school lighting standards including products and lighting fixtures.

At present, the people's demands and voices for "favoring study" are becoming more and more intense. One of the important ways to solve "favoring study" is to realize the standardization of educational equipment. The establishment of the "School Lighting Environment Research Center" is a step in the construction of practical education equipment standardization and is a meaningful measure for students to "get ready to learn." In the follow-up, the center will effectively strengthen the standardized construction and use of lighting environments in school health classrooms, and lay the foundation for truly popularizing the lighting environment of school healthy classrooms. Allow students to feel at ease in a healthy light environment, grow healthy and have good vision!
