1. A deformable light emitting diode (LED) lamp configured to change a light emitting angle by folding, comprising:
a fixed light source,
one or more movable light sources, and
an end cover, wherein:
the one or more movable light sources are rotatably connected to the end cover through a rotating shaft,
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,
each of the fixed light source and the one or more movable light sources comprises an LED light source board and a heat sink,
one side of the LED light source board facing away from a light emitting surface of the LED light source board is connected with the 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,
the end cover comprises a first end cover and a second end cover, and
the first end cover and the second end cover are fixedly connected together through a buckle structure and a first bolt to enable a switch for controlling the fixed light source and the one or more movable light sources to be clamped therebetween.
