阅览区照明的专业线是'纸面 vs 屏幕'：纸质阅读要均匀无影，电子屏阅读要防反光，现在读者两样都用，桌面照明必须两头兼顾。
桌面维持300lx（GB50034图书馆阅览）、均匀度≥0.7；灯具采用格栅防眩UGR≤19；屏幕区桌面亮度与屏幕亮度比控制在1:3内防止视觉疲劳。
我们的阅览区方案做了桌面照度九宫格实测，任何座位起身换桌前后亮度差不超过10%，选座焦虑减少。
Reading-room lighting now straddles paper and screen: paper wants uniform shadow-free light, screens hate reflections — readers use both, so desktops must serve both.
Desks 300 lx maintained (GB50034 libraries) with uniformity ≥0.7; louvred luminaires at UGR≤19; desk-to-screen luminance ratio held within 1:3 to fight visual fatigue.
Our reading-room design is verified by a nine-point desk grid: moving to any seat changes illuminance under 10% — seat-selection anxiety gone.
