教室照明是政府督办项目：课桌面照度不达标、黑板反光、频闪，直接对应青少年近视率——这不是美学问题，是民生指标。
执行GB7793-2010：课桌面维持300lx、黑板面500lx且黑板灯不产生直接眩光；RG0无蓝光危害、波动深度达标防频闪；教室统一3000-4000K可调。
我们承接的教室改造全部按'检前基线-改造-检后复测'三步走，复测报告直接交付教育部门备案。
Classroom lighting is a government-supervised item: desk illuminance, blackboard glare and flicker map directly to youth myopia rates — not aesthetics but a public-health metric.
Per GB7793-2010: desks 300 lx maintained, blackboards 500 lx without direct glare; RG0 blue-hazard-free, flicker-compliant drivers; unified 3000-4000K tunable.
Every classroom retrofit we deliver follows baseline test, upgrade, then re-test — final reports filed directly with education authorities.
