Feng Zhaoyang, member of the Guangzhou CPPCC: "Reinforcement" of indoor lighting in school classrooms to provide greater support for myopia prevention and control

At this year's two sessions in Guangzhou, Feng Zhaoyang, a member of the Guangzhou Municipal People's Political Consultative Conference, submitted a proposal to help students prevent and control myopia by "reinforcing" school classroom lighting. He said that in recent years, Guangzhou has issued a number of working documents such as the "Guangzhou Comprehensive Prevention and Control of Myopia in Children and Adolescents" and other working documents to ensure students' daily outdoor activity time, comprehensively improve indoor lighting and lighting conditions in classrooms and other places, and has been at the forefront of the country in helping myopia prevention and control by improving classroom lighting levels. "But the situation of student myopia prevention and control is serious."

Feng Zhaoyang explained that between 2018 and 2019, with the support of urban financial investment, Guangzhou upgraded the lighting of tens of thousands of classrooms in primary and secondary schools across the city. Few people know that the core of this is to use lamps with a ratio of upward luminous flux accounting for 50% of the total luminous flux, improving ceiling illumination and effectively increasing the brightness of the peripheral area of ​​​​the work surface. However, over the years, the light source of the classroom lighting system has declined, and after-sales services have been interrupted. The existing lighting may not necessarily meet the original core standards. He suggested carrying out a lighting census and increasing double random inspections.

In addition to the conventional desktop illumination and uniformity, blackboard illumination and uniformity, glare, color temperature and other general lighting indicators, Feng Zhaoyang suggested focusing on testing whether the upward light flux reaches the standard requirement of 30% to 50% of the total light flux to ensure that the ceiling, wall and desktop lighting are consistent. and maintain the classroom lighting equipment that was installed between 2018 and 2019 and before and is still in normal use today. The original suppliers are urged to provide or extend after-sales maintenance services to further ensure that the lighting system operation maintains the original execution standards.

As for the newly installed classroom lighting equipment, Feng Zhaoyang believes that its upward luminous flux should be consistent with the standard of 50% of the total luminous flux of other classroom lighting, in order to maximize the lighting effect and help with myopia prevention and control.
