仓库照明的通病是『货架亮、通道暗』：点位照度够，但巷道与货架间的照度落差太大，叉车司机看错货位、拣货效率低。
一般件库 100lx、精细件库 200lx、货架垂直照度不低于 50lx（GB50034 仓库），显色指数 Ra≥80 区分包装颜色，高天棚灯配防眩格栅把 UGR 控制在≤25 以下。
曦韵做仓库照明先算『货架面照度』而非地面照度，用高天棚灯加巷道专用配光，让每层货位的垂直照度都达标，拣货差错率与叉车作业时间同步下降。
The classic warehouse flaw is bright racks, dark aisles: point readings pass but the contrast between rack and aisle is so steep that forklift drivers misread locations and picking slows.
General storage 100 lx, fine-parts storage 200 lx, rack vertical illuminance not below 50 lx (GB50034), Ra>=80 for package colour coding, and anti-glare high-bay luminaires keeping UGR<=25.
Xiyun designs to rack-face illuminance, not the floor: high-bays with aisle-specific optics bring every shelf level up to standard, cutting picking errors and forklift cycle time together.
