To improve the lighting environment of the classroom, these parameters and indicators are crucial!


In recent years, the problem of myopia among children and adolescents in China is serious, and the rate of myopia remains high. In addition to holidays, primary and secondary school students spend about 5 to 8 hours in the classroom every day.

The light environment in classrooms has an important impact on the visual development of children and adolescents.

Improving the classroom light environment is an effective means to reduce students' visual fatigue and thereby reduce their myopia rate.

The "Implementation Plan for Comprehensive Prevention and Control of Myopia in Children and Adolescents" jointly issued by 8 ministries and commissions, including the National Health Commission, clearly states that "it is necessary to improve the visual environment, implement classroom lighting and lighting requirements, and use lighting equipment conducive to visual health.".

Relevant research has shown that poor classroom lighting environment is one of the main reasons for students' visual impairment. According to a survey, primary and secondary school students in China spend about 60% of their time in the classroom every day and are exposed to unhealthy lighting conditions for a long time: low light can bring visual fatigue; Excessive glare can cause the book in your hand to reflect light; Inefficient light sources cause low illumination on the desktop. Over time, changes in the refractive system of the eye will naturally occur, leading to myopia. The lighting environment in classrooms directly determines the eye hygiene and the incidence of myopia among adolescents.

Currently, some school classrooms maintain an average illuminance of 100-200lx on their desks, with an illuminance uniformity of around 0.5, which is far below the lower limit requirements of the national standard: 300lx and 0.7. Problems such as dim classrooms, uneven illumination, and severe glare still exist.

In view of this, the Ministry of Education and other 15 departments jointly formulated the "Action Plan for Preventing and Controlling Myopia in Children and Adolescents (2021-2025).". The plan clearly proposes to improve the visual environment of students and implement lighting and lighting requirements for classrooms, dormitories, libraries, etc.

1. Introduction to Lighting Environmental Standards for Classroom Lighting

What are the standards for classroom lighting now? What parameters and indicators need to be met?

According to the requirements for classroom lighting, the current national standards mainly include the following four:

-GB 7793-2010 Hygienic Standard for Lighting and Lighting of Classrooms in Primary and Secondary Schools

-GB 50034-2013 Standard for Lighting Design of Buildings

-GB/T 36876-2018 Hygienic Requirements for Lighting Design and Installation of General Classrooms in Primary and Secondary Schools

-GB 40070-2021 Health Requirements for Myopia Prevention and Control of Children and Adolescent Learning Goods (for products)

2. Requirements for key technical indicators

<Comparison of eight key technical indicators>

Through comprehensive comparison, the key technical indicators can be summarized as follows:

1. The class desktop maintains illumination ≥ 300lx,

2. The uniformity of illumination on the desk is ≥ 0.7,

3. Blackboard maintenance illumination ≥ 500lx,

4. Blackboard illumination uniformity ≥ 0.8,

5. Power density ≤ 9W/m ²,

6. Color rendering index Ra ≥ 80, R9>0,

7. Color temperature 3300-5300K,

8. Uniform glare value ≤ 19.

Indicators 1-4 can be detected by an illuminometer, while indicators 5-8 require professional equipment testing.
