A lamp holder includes a frame seat (1), a rotatable seat (2), a lens unit (3) and a watertight elastic unit (4). The frame seat (1) includes a barrel wall (11) surrounding a first axis (L1) and defining a rotating space (111). The rotatable seat (2) is disposed in the rotating space (111), and has an outer surrounding surface (211), a connecting end (216) cooperating with an installing end (13) of the barrel wall (11) to define a gap (217) therebetween, and two rotating studs (218) extending from the outer surrounding surface (211) to the barrel wall (11) such that the rotatable seat (2) is rotatable about a second axis (L2) relative to the frame seat (1). The lens unit (3) is in watertight connection with the rotatable seat (2) . The watertight elastic unit (4) is made of an elastic material, and interconnects the installing end (13) and the connecting end (216) to completely block the gap (217). |
