Hubei finds out the lighting quality of classrooms in primary and secondary schools
Vision health is related to the growth and future of every child. In order to do a good job in the prevention and control of myopia in children and adolescents, from January 9 to February 20, 2023, 10 technical experts from the Mechanical and Electrical Products Testing Institute of Hubei Provincial Quality Inspection Institute The lighting research team traveled to 12 prefecture-level cities, 1 autonomous prefecture, and 4 provincial counties in Hubei Province to carry out targeted inspections on the lighting quality of 33 primary and secondary classrooms.
Strictly formulate evaluation indicators to find out the quality of classroom lighting
The classroom lighting quality evaluation aims to further standardize the market order of the classroom lighting renovation industry in Hubei Province, comprehensively evaluate the overall quality of classroom lighting environment in primary and secondary schools in Hubei Province, and provide data support for the introduction of regulations in related fields.
When the working group formulates the lighting quality evaluation indicators, it gives priority to the inspection items stipulated in the mandatory national standards. For items with inconsistent limit values in the standard, refer to the local standard limit values of advanced provinces and cities in China, and combine the characteristics of our province to formulate an evaluation guide that is in line with the actual situation of our province, and make a reasonable evaluation of the overall quality of classroom lighting in primary and secondary schools.
The evaluation indicators of the classroom lighting quality mainly include the average illuminance and illuminance uniformity of the classroom desktop, the average illuminance and illuminance uniformity of the blackboard surface, correlated color temperature, uniform glare value, and the fluctuating depth of the classroom and blackboard surface. Among them, if the correlated color temperature is too low, it will reduce attention and concentration, and if it is too high, it will easily cause visual fatigue; the fluctuation depth is an index to measure the stroboscopic size of the light source. Reading under the stroboscopic light source for a long time will cause eye fatigue, Soreness and even damage to the optic nerve.
Carefully analyze quality data and actively improve relevant field specifications
Monitoring data show that the myopia rate of young students in my country is gradually showing a trend of younger and more severe myopia, seriously affecting the physical and mental health of young students. The classroom is the main place for students to learn, and the lighting environment is an important factor affecting students' vision. The Ministry of Education of the People's Republic of China has repeatedly issued a request to strengthen the supervision and inspection of schools to implement relevant standards for myopia prevention and control, organize random sampling inspections of lighting and lighting, and strive to achieve a 100% compliance rate of school classroom lighting hygiene standards.
As a major province of education, Hubei Province actively responded to the call of the country. In 2019, it issued the "Implementation Plan for Comprehensive Prevention and Control of Myopia in Children and Adolescents in Hubei Province" to guide primary and secondary schools in Hubei Province in the prevention and control of myopia in children and adolescents. In 2022, in order to solve the dilemma that there is no guiding technical document for classroom lighting renovation in our province, it will be under the jurisdiction of the Hubei Provincial Health and Health Commission, compiled by the Hubei Provincial Quality Inspection Institute, and jointly with the Hubei Provincial Center for Disease Control and Prevention, Hubei Provincial Educational Equipment Department, etc. The local standard project "Lighting Management Specifications for Primary and Secondary Schools, Kindergarten Classrooms and Off-campus Teaching Places" declared by many units has been approved for project approval, which will provide unified specifications for the design, purchase, installation and acceptance of educational institutions and construction units.
In the next step, the Hubei Quality Inspection Institute will further analyze and explore the lighting quality data of 33 primary and secondary schools. Data support enables inspection and testing to serve the focus of people's livelihood, strengthens the prevention and control of myopia, and protects the bright future of the flowers of the motherland.
