Abstract
A deformable LED lamp configured to change a light emitting angle by folding comprises a fixed light source, one or more movable light sources, and an end cover. The one or more movable light sources are rotatably connected to the end cover through a rotating shaft, and the one or more movable light sources are configured to rotate about the rotating shaft to change an included angle between the fixed light source and the one or more movable light sources. One side of a LED light source board facing away from a light emitting surface of the LED light source board is connected with a heat sink to enable heat conduction between the LED light source board and the heat sink. The heat sink of the fixed light source and the heat sink of the one or more movable light sources are rotatably connected together through a hinge.
