Bedlamp → It is formed from "bed" (from Old English *bedd*, meaning a place for sleeping) and "lamp" (from Old French *lampe*, meaning a device that produces light). The word "bedlamp" refers to a lamp designed specifically for use beside a bed, providing light for reading or other activities in bed.
Think of a 'place for sleeping' ('bed') and a 'device that produces light' ('lamp') — together, they create a lamp meant for use next to your bed.
