Most of the lamp beads on the existing market emit fixed light, and users cannot adjust the brightness of the lamp bead according to functional requirements during use, which is rather inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide an LED lamp bead with a direction adjustment structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an LED lamp bead with a direction adjustment structure, including a base, a rotation mechanism is arranged at the upper end of the base, and a light-emitting mechanism is arranged inside the rotation mechanism;

[0006] The rotation mechanism includes a circular groove, which is opened at the center of the upper surface of the base. A transparent rotating block is rotatably connected inside the circular groove. Two sliding grooves are opened on the outer circular side wall of the transparent rotating block. Sliders are slidably connected inside both sliding grooves. Two arc-shaped plates are symmetrically and fixedly connected to the upper surface of the base, and a light-shielding plate is fixedly connected to the upper end of each of the two arc-shaped plates;

[0007] The light-emitting mechanism includes a circular cavity, which is opened inside the transparent rotating block. A circuit board is embedded inside the circular cavity. A power cord is fixedly connected to the lower surface of the circuit board, and the lower end of the power cord is inserted into the inside of a rotating groove, which is opened on the lower outer wall of the base. A plurality of wires are fixedly connected to the upper end of the circuit board. The upper ends of the plurality of wires pass through the upper inner wall of the circular cavity and extend into two arc-shaped cavities. The upper ends of the plurality of wires are fixedly connected with light-emitting diodes, and the plurality of light-emitting diodes are respectively clamped inside the two arc-shaped cavities. The two arc-shaped cavities are symmetrically opened inside the upper end of the transparent rotating block.

[0008] Preferably, the two light-shielding plates are respectively clamped on the upper surfaces of both ends of the transparent rotating block.

[0009] Preferably, the two sliding grooves are staggeredly arranged on the outer circumferential side wall of the transparent rotating block, and the length of the two sliding grooves is one-fourth of the circumference of the transparent rotating block.

[0010] Preferably, the two arc-shaped cavities are both arranged around the center of the transparent rotating block, and the two arc-shaped cavities respectively correspond to the two light-shielding plates.

[0011] Preferably, the distance between the arc-shaped cavity and the center of the transparent rotating block is longer than the distance between the light-shielding plate and the center of the transparent rotating block.

[0021] The rotation mechanism 2 includes a circular groove 21, the circular groove 21 is opened at the center of the upper surface of the base 1, a transparent rotating block 22 is rotatably connected inside the circular groove 21, two sliding grooves 23 are opened on the outer circumferential side wall of the transparent rotating block 22, and two sliding blocks 24 are slidably connected inside the two sliding grooves 23. Two arc plates 25 are symmetrically and fixedly connected to the upper surface of the base 1, and a light shielding plate 26 is fixedly connected to the upper end of each of the two arc plates 25. The rotation trajectory of the transparent rotating block 22 is restricted by the sliding groove 23 on the surface of the transparent rotating block 22 and the sliding block 24 on the inner wall of the circular groove 21, preventing the transparent rotating block 22 from rotating too much and damaging the power cord 33;

[0022] The light emitting mechanism 3 includes a circular cavity 31, the circular cavity 31 is opened inside the transparent rotating block 22, a circuit board 32 is embedded inside the circular cavity 31, a power cord 33 is fixedly connected to the lower surface of the circuit board 32, the lower end of the power cord 33 is inserted into the inside of the rotating groove 34, and the rotating groove 34 is opened on the outer wall of the lower end of the base 1. The upper end of the circuit board 32 is fixedly connected with a plurality of conducting wires 35, the upper ends of the plurality of conducting wires 35 pass through the upper inner wall of the circular cavity 31 and extend into two arc-shaped cavities 37, the upper ends of the plurality of conducting wires 35 are fixedly connected with light emitting diodes 36, and the plurality of light emitting diodes 36 are respectively clamped inside the two arc-shaped cavities 37. The two arc-shaped cavities 37 are symmetrically opened inside the upper end of the transparent rotating block 22. When the light emitting diode 36 rotates, it rotates to the lower end of the light shielding plate 26, and the light emitting diode 36 is blocked by the light shielding plate 26, thereby reducing the brightness of the light emitted by the light emitting diode 36. Rotate the transparent rotating block 22 according to the needs to adjust the direction of the light emitting diode 36, so that the redundant light emitting diodes 36 are blocked by the light shielding plate 26, and thus the light emitted by the 36 without the light brightness adjustment function can be adjusted according to the needs.

[0023] The two light shielding plates 26 are respectively clamped on the upper surfaces of both ends of the transparent rotating block 22, and thus the transparent rotating block 22 is clamped by the light shielding plates 26.

[0024] The two sliding grooves 23 are staggeredly opened on the outer circumferential side wall of the transparent rotating block 22, and the length of the two sliding grooves 23 is one-fourth of the circumference of the transparent rotating block 22, thereby fixing the rotation angle of the transparent rotating block 22 and preventing the transparent rotating block 22 from rotating too much and damaging the power cord 33.

[0026] The distance between the arc-shaped cavity 37 and the center of the transparent rotating block 22 is longer than the distance between the light-shielding plate 26 and the center of the transparent rotating block 22, so that the light-shielding plate 26 can block the light emitted by the light-emitting diode 36 inside the arc-shaped cavity 37.

[0027] The upper and lower ends of the power cord 33 are arranged staggeredly, so that the power cord 33 can rotate at a certain angle.

When the arc-shaped cavity 37 rotates, drive the light-emitting diode 36 to rotate. When the light-emitting diode 36 rotates, it rotates to the lower end of the light-shielding plate 26. Block the light-emitting diode 36 through the light-shielding plate 26, so that the brightness of the light emitted by the light-emitting diode 36 is reduced. Rotate the transparent rotating block 22 according to the needs to adjust the direction of the light-emitting diode 36, so that the redundant light-emitting diodes 36 are blocked by the light-shielding plate 26, so that the light emitted by the 36 without the light brightness adjustment function can be adjusted according to the needs. Limit the rotation trajectory of the transparent rotating block 22 through the sliding groove 23 on the surface of the transparent rotating block 22 and the sliding block 24 on the inner wall of the circular groove 21 to prevent the transparent rotating block 22 from rotating too much and damaging the power cord 33.
