Light emitting diode (LED) lamp with adjustable space illumination angle

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.

2. The LED lamp with the adjustable space illumination angle according to claim 1 , wherein:

each of the two movable light sources comprises a light source assembly, a lamp shade, a first end cover, and a second end cover,

the first end cover and the second end cover are disposed on two sides of the lamp shade in a length direction of the lamp shade, and

the second end cover is rotatably connected to the lamp head assembly.

3. The LED lamp with the adjustable space illumination angle according to claim 2 , wherein:

the second end cover is rotatably connected with the first rotating shaft through a first pressed cover, and

the first rotating shaft is configured to drive the first pressed cover to rotate about the X-axis.

4. The LED lamp with the adjustable space illumination angle according to claim 3 , wherein:

one side of the first rotating shaft away from the second end cover is disposed in a slot of the first part and is rotatably connected with the slot of the first part through a second rotating shaft, and

the second rotating shaft is configured to drive the first pressed cover to rotate about the Y-axis.

5. The LED lamp with the adjustable space illumination angle according to claim 4 , wherein:

the second rotating shaft is a rotating shaft threaded rod passing through the slot of the first part to be fixedly connected to a rotating shaft nut.

6. The LED lamp with the adjustable space illumination angle according to claim 2 , wherein:

the light source assembly comprises one or more lamp beads and an aluminum substrate, and

the aluminum substrate is attached to an inner portion of the lamp shade through an inner clamping groove of the lamp shade.

7. The LED lamp with the adjustable space illumination angle according to claim 2 , wherein an end of the first rotating shaft away from the second end cover comprises the buckle teeth.

8. The LED lamp with the adjustable space illumination angle according to claim 1 , wherein:

an infrared sensing module is disposed on the first part.

9. The LED lamp with the adjustable space illumination angle according to claim 1 , wherein the pushable piece is independently disposed on the first part.
