用切割面板做的壁灯基本走两条路：一种是木质或亚克力的壁灯罩，把小灯泡或 LED 灯饼藏在镂空图案后面；另一种是分层光板，几片薄板中间留缝叠起来，光就在墙上散得不均匀，形成层次。几何和植物镂空纹样最常见，因为塑造光形的是留白本身，不是油漆或额外装饰。前层常选亚克力，让光扩散得更匀；背后用木头或密度板做块体安放电气件，也让灯具贴墙不留缝。
What is the difference between a wall sconce and a wall lamp?
A wall sconce is typically fixed in place, hardwired or plugged into a nearby outlet, and often used in pairs to flank a mirror or hallway. A wall lamp usually refers to a more adjustable fixture, sometimes with a swing arm, meant for reading or task lighting beside a bed or chair. The two terms often overlap in casual use.
