钢结构厂房的特点是『高、大、空的金属空间』，光在钢构件与屋面之间来回反射，既难做均匀照明，又容易产生刺眼反光。
一般生产区 200-300lx、组装与检验区不低于 300lx，高天棚灯具 UGR≤25 控制金属面眩光、Ra≥80，灯具需适应钢构振动与高粉尘环境。
曦韵做钢结构厂房照明先做光线追踪模拟，用精准配光减少无效散射，让同样照度下灯具数量更少、能耗更低；高天棚灯配防震支架适应钢结构振动。
Steel sheds are tall, vast metal voids where light bounces between members and roof, making even illumination hard and glare easy.
General production 200-300 lx, assembly and inspection >=300 lx, high-bays UGR<=25 against metal glare, Ra>=80, built for structural vibration and heavy dust.
Xiyun ray-traces steel-shed projects first, using precision optics to cut wasted scatter so fewer fixtures hit the same illuminance, with anti-vibration mounts for structural sway.
