In May 2021, the Ministry of Education and other 15 departments jointly issued the "Bright Action Work Plan for the Prevention and Control of Myopia in Children and Adolescents (2021-2025)" (hereinafter referred to as "Bright Action"), proposing to take targeted measures for the prevention and control of myopia in different school stages, different types of schools, and different regions, to reduce the incidence of new myopia, slow the progress of myopia, and reduce the rate of severe myopia. The "Bright Action" proposes to unite the efforts of the government, schools, medical and health institutions, students, families, society, and other parties, take multiple measures simultaneously, divide responsibilities, and act in concert to jointly promote the prevention and control of myopia among children and adolescents.

The "Bright Action" plan explicitly requires improving the visual environment of students. Guide local areas to improve teaching facilities and conditions, implement lighting and lighting requirements for classrooms, dormitories, libraries (reading rooms), and encourage the purchase of standard adjustable desks, chairs, and posture correctors to provide students with a learning environment that meets eye hygiene requirements. Strictly comply with the Hygienic Requirements for the Prevention and Control of Myopia in Children and Adolescents' Learning Goods to ensure that children and adolescents use classroom lighting fixtures, reading and writing desk lamps, teaching multimedia, and other children and adolescents' learning goods that meet the hygiene requirements.

Classroom lighting is closely related to myopia prevention and control. Too strong or too weak light can have a negative impact on students' eyesight, increasing the risk of myopia. If the lighting in the classroom is too weak, students need to use more eyesight to see the text on the blackboard and books, which can easily lead to eye fatigue, decreased vision, and even myopia over time; Excessive illumination can produce strong light reflections and glare, which can also harm students' eyesight. Therefore, moderate and balanced lighting is very important.

In addition, when conducting myopia prevention and control, it is also necessary to pay attention to the color temperature selection of classroom lighting. Higher color temperatures (such as above 6000K) are prone to blue light, and prolonged exposure to this light can have a negative impact on the eyes. Therefore, selecting a lower color temperature (such as 4000-5000K) can effectively reduce the damage of blue light to the eyes.

Educational lighting products mainly include LED lamps, intelligent control systems, sensor equipment, etc. LED lamps adopt high-efficiency and energy-saving LED light sources, which have the characteristics of good color restoration, long service life, and good seismic performance; The intelligent control system can automatically adjust the light according to different time periods and scenarios to achieve energy saving and consumption reduction. In terms of educational lighting technology, artificial intelligence technology is gradually being applied to lighting control, such as real-time collection of environmental data through sensors, intelligent decision-making, and achieving more intelligent and accurate control of lighting.

According to the results of the "National Myopia Survey of Children and Adolescents" conducted by the National Health Commission in 2022, currently, China has nearly 700 million myopia patients, and the adolescent myopia rate ranks first in the world. The prevalence of myopia among junior and senior high school students has exceeded 70% and is increasing year by year. The myopia rate among primary school students is also approaching 40%. In China, primary and secondary school students spend an average of 60% of their time in the classroom every day, and substandard and unhealthy classroom light environment is one of the main reasons for the decline in eyesight of primary and secondary school students.

As a promoter of campus lighting and light health, Huahui Lighting has been deeply involved in the lighting industry for 28 years, and is one of the first units to meet the standards for high-quality lighting and light environment in classrooms in South China. It is also one of the "Top Ten Educational Lighting Brands" in the lighting industry in 2022 in China. It strictly controls color temperature, glare, blue light, illuminance, and other issues in educational lighting, to avoid harmful lighting effects on students' visual health.

Huahui Lighting has designed special lighting fixtures for classroom lighting - led eye protection classroom lights and led eye protection blackboard lights, which meet national standards and maintain an average (constant) illumination of more than 300lx for desks, with an illumination uniformity of 0.7; The blackboard maintains an average (constant) illumination of 500lx and an illumination uniformity of 0.8; The color rendering index is greater than 90, and the color reversibility is high; Adopt grille anti glare design, with glare value less than 16, not dazzling; The color temperature is 5000K, comfortable and soft; The illumination of the entire classroom is uniform, without stroboscopic flashes or blue light hazards.

Huahui LED eye protection classroom lamp and LED eye protection blackboard lamp meet and exceed the provisions of the "Hygienic Standards for Lighting and Lighting in Primary and Secondary School Classrooms". The lamp technology is mature and meets national certification requirements such as CCC and CE. The entire lamp uses RG0 classroom dedicated anti blue light beads, with a glare value of<16, a color temperature of 5000K, and Ra>95, to ensure uniform classroom illumination, effectively protect eyesight, and prevent myopia.

In order to improve the poor classroom lighting environment, in addition to selecting high-quality and healthy classroom eye protection lamps, it is also necessary to have classroom lighting solutions suitable for local school lighting transformation. Huahui Lighting's independently developed intelligent educational lighting products (Huahui LED intelligent classroom lights and Huahui LED intelligent blackboard lights), coupled with Huahui AIoT intelligent educational lighting overall solution, can be used for different school transformation standards and different classroom lighting types, Use intelligent full touch screen scene switches, remote controls, or mobile phone apps to easily switch various lighting modes required for teaching, achieving multiple intelligent requirements such as constant illumination throughout the classroom, one-touch scene control, curtain linkage, and ultraviolet disinfection!
