1. A light emitting diode (LED) lamp with an adjustable space illumination angle, comprising:
two movable light sources, and
a lamp head assembly, wherein:
the two movable light sources are disposed on two sides of the lamp head assembly and spaced apart from each other in a length direction of the lamp head assembly,
the two movable light sources are rotatably connected to the lamp head assembly,
the two movable light sources are configured to be rotated about an X-axis and a Y-axis to change an included angle between the two movable light sources,
the lamp head assembly comprises a first part connected with the two movable light sources and a second part connected with a lamp holder,
the first part is rotatably connected to the second part so as to enable the two movable light sources and the first part to rotate relative to the second part about a Z-axis
the first part comprises a pushable piece,
a side wall of a first rotating shaft of each of the two movable light sources comprises buckle teeth along a rotating direction of the first rotating shaft about the Y-axis,
when the two movable light sources rotate about the Y-axis, the pushable piece is separated from the buckle teeth, and
when the two movable light sources stop rotating about the Y-axis, the pushable piece is automatically buckled to any one of the buckle teeth to restrict rotation of the two movable light sources to be limited to a position corresponding to the any one of the buckle teeth due to a spring connected to the pushable piece.
