Abstract
An LED lamp with an adjustable space illumination angle comprises two movable light sources and a lamp head assembly. 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 or 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, and 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.
