The support rod 2 is rotatably connected to the middle of the top of the base 1, and the connecting rod 3 is rotatably connected to one end of the support rod 2 away from the base 1;

[0029] One end of the connecting rod 3 away from the support rod 2 is provided with an adjusting structure. The adjusting structure is provided with a protective cover 10, and a reflecting disc 11 is fixedly connected inside the protective cover 10. And an LED lamp 12 is fixedly connected to the middle of the reflecting disc 11. A plurality of connecting rotating shafts 13 distributed in a ring are fixedly connected to the side of the reflecting disc 11, and each connecting rotating shaft 13 is rotatably connected with a reflecting plate 14;

[0030] The connecting rotating shaft 13 is set as an elastic rotating shaft, and the connecting rotating shaft 13 drives each reflecting plate 14 to rotate towards the inner side of the reflecting disc 11. The plurality of reflecting plates 14 distributed in a ring are distributed on the side of the reflecting disc 11 in a ring, and both sides of each reflecting plate 14 are in contact with other reflecting plates 14, and the plurality of reflecting plates 14 form an interconnected whole.

[0031] The support rod 2 and the connecting rod 3 are vertically distributed at the connection, and an installation groove 4 is arranged inside one end of the connecting rod 3 away from the support rod 2. And a positioning screw 5 is threadedly connected to the inner side of the lower end of the installation groove 4 close to one side of the connecting rod 3.

[0032] The inner side of the lower end of the installation groove 4 is rotatably connected with a connecting block 6, and a positioning groove 7 is arranged along the middle of the outer side of the connecting block 6. And one end of the positioning screw 5 located inside the installation groove 4 is engaged with the inside of the positioning groove 7.

[0033] One end of the connecting block 6 away from the installation groove 4 is fixedly connected with an adjusting frame 8, and one end of the adjusting frame 8 away from the connecting block 6 is fixedly connected with a support frame 9. And one end of the support frame 9 away from the adjusting frame 8 is fixedly connected with the protective cover 10.

[0034] Inside the protective cover 10, an adjusting ring 15 is provided, and the inner sides of the adjusting ring 15 are in mutual contact with the outer sides of each reflector 14. Moreover, four annularly distributed control frames 16 are fixedly connected to the bottom of the adjusting ring 15 away from the reflector 14, and the four annularly distributed control frames 16 penetrate through the bottom of the protective cover 10.

[0035] The four control frames 16 are bent towards the inner side of the bottom of the protective cover 10, and a driving ring is fixedly connected to the intersection of the bent ends of the four control frames 16. Moreover, a lead screw 17 is threadedly connected inside the driving ring. The lead screw 17 is rotatably connected to the middle of the support frame 9, and the lead screw 17 extends towards the protective cover 10.

[0036] Embodiment 2:

[0037] On the basis of Embodiment 1, its specific working principle is as follows:

[0038] This LED reflector with a rotating light-condensing adjusting structure is provided with an adjusting structure. A plurality of annularly distributed reflectors 14 and a reflecting disc 11 together form an integral reflector structure. Since the connecting rotating shaft 13 always drives the reflector 14 to rotate around the connecting rotating shaft 13 towards the outside of the reflecting disc 11, when the reflector 14 rotates towards the outside of the reflecting disc 11, it will come into contact with the inner side of the adjusting ring 15. The rotating angle of the plurality of reflectors 14 is restricted by the adjusting ring 15, thereby restricting the angle between the reflector 14 and the reflecting disc 11;

[0039] Furthermore, when the adjusting ring 15 contacts the reflector 14, the position of the adjusting ring 15 on the outside of the reflector 14 is controlled by the control frame 16, and the position of the control frame 16 inside the protective cover 10 is controlled by the driving ring at the intersection of the bent ends of the four control frames 16. Therefore, when the lead screw 17 is rotated, the lead screw 17 will drive the driving ring to move on its outside, thereby adjusting the position of the adjusting ring 15 on the reflector 14. When the adjusting ring 15 is away from the reflector 14, at this time, the reflector 14 will be driven by the connecting rotating shaft 13 to approach the inner side of the protective cover 10, so that the inner diameter of the annular structure formed between the plurality of reflectors 14 increases, and further, the reflector 14 and the reflecting disc 11 together form a reflector to increase the reflection angle of the light, increasing the reflection range of the light. On the contrary, when the adjusting ring 15 approaches the reflector 14 and contacts the outside of the reflector 14, at this time, the reflector 14 will rotate around the connecting rotating shaft 13, so that the inner diameter of the annular structure formed between the plurality of reflectors 14 decreases, and further, the reflector 14 and the reflecting disc 11 together form a reflector to reduce the reflection angle of the light, reducing the light reflection range, and achieving the light-converging effect;

[0040] Furthermore, by rotating the connecting block 6 inside the installation groove 4 and controlling the angle of the connecting block 6 on the inner wall of the installation groove 4 through the engagement of the positioning screw 5 with the positioning groove 7, the angle between the adjusting frame 8 and the connecting rod 3 can be adjusted and fixed, so as to adjust the reflection angle of the light. The support rod 2 and the connecting rod 3 can rotate independently of each other, and the connecting rod 3 and the support rod 2 can rotate independently of each other. Therefore, by adjusting the rotation angles of the connecting rod 3 and the support rod 2, the position of the light irradiation can be adjusted.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
