1. 吊顶支架制作
测量天花板与混凝土距离，焊接上盘与下盘
Measure distance between ceiling and concrete, weld upper and lower plates
1
测量天花板与混凝土顶之间的高度，选用钢筋/钢管等材料将上盘（9孔）与下盘（4孔）焊接牢固。
Measure distance between finished ceiling and concrete structure. Weld upper plate (9 holes) and lower plate (4 holes) using rebar/steel pipe.
Measure distance between finished ceiling and concrete structure. Weld upper plate (9 holes) and lower plate (4 holes) using rebar/steel pipe.
2
使用膨胀螺栓将上板固定于混凝土顶部，下板与手术灯底座用螺丝连接。
Fix upper plate to concrete ceiling with expansion bolts. Connect lower plate to lamp base with screws.

最佳安装高度 2700mm – 3000mm
Optimal ceiling height: 2700–3000 mm
1
测量已完成装修的地面至天花板的垂直距离。
Measure vertical distance from finished floor to finished ceiling.

若高度在2700-3000mm之间，手术灯可正常安装并达到最佳照明效果。
If measured height is between 2700 mm and 3000 mm, lamp can be installed normally with best lighting effect.
