Abstract: A reversible LED lamp has a fixed support including first and second plate bodies. One side of the first body is connected to the second; the other is connected to a first limiting member. A rotating support includes a third plate body and rotating support member. One side of the third body is connected to a first rotating portion; the other side is connected to the rotating support member, below the second and third bodies. A side of the rotating support member close to the second body is flush therewith. The plate bodies and rotating support member form a power supply installation space. A light-emitting assembly is in a light source installation space in the rotating support member. When a power supply in the power supply installation space is repaired/replaced, the rotating support is unfolded. The rotating support is rotatable in the fixed support, which has an avoidance groove.
