DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0026] Referring to Figures 1 to 6 As shown, to achieve the above object, the present utility model provides the following technical solution: A table lamp includes a lamp base 1, a lamp post 2 and a light source assembly 3. The lamp post 2 is installed on the lamp base 1, the light source assembly 3 is installed inside the lamp post 2, a light-emitting hole 21 is provided on the lamp post 2, and a light-shielding assembly 4 is provided at the light-emitting hole 21.

[0027] The light-shielding assembly 4 includes a light-shielding disc 41, a light-shielding plate 42 and a rotating ring 43. The light-shielding disc 41 is fixedly installed inside the lamp post 2, and a light-emitting groove 411 corresponding to the light-emitting hole 21 is provided on the light-shielding disc 41. A plurality of groups of light-shielding plates 42 are provided and are arranged in a circumferential pattern on the light-shielding disc 41. One end of the light-shielding plate 42 is rotatably connected to the light-shielding disc 41, and the other end is connected to the rotating ring 43.

[0028] The rotating ring 43 is rotatably connected inside the lamp post 2.

[0029] With the design of the present utility model, by rotating the rotating ring 43, the rotating ring 43 can drive a plurality of groups of light-shielding plates 42 to move, thereby blocking the light-emitting groove 411, controlling the effective light-emitting area, and achieving the effect of adjusting the irradiation range.

[0030] The present utility model is further provided as: an installation hole 412 is provided on the light-shielding disc 41, a rotating block 421 is provided on one side of the light-shielding plate 42, and the light-shielding plate 42 is rotatably connected inside the installation hole 412 through the rotating block 421.

[0031] As Figure 4 shown, with the design of this structure, during the rotation of the rotating ring 43, one end of the light-shielding plate 42 can perform a circular motion with the installation hole 412 as the fulcrum. And since a plurality of groups of light-shielding plates 42 are installed staggeredly, during the rotation, the light-shielding plates 42 will not collide with each other.

[0032] The present utility model is further provided as: a guiding groove 431 is provided on the rotating ring 43, a guiding block 422 is provided on the other side of the light-shielding plate 42, and the light-shielding plate 42 is connected inside the guiding groove 431 through the guiding block 422.

[0033] As Figure 5As shown, when the rotating ring 43 rotates, one end of the light-shielding plate 42 is driven by the guiding groove 431 to move in an arc, thereby achieving the function of adjusting the size of the central position hole.

[0034] The present utility model is further configured such that one end of the lamp post 2 is hingedly disposed on the lamp base 1. The lamp post 2 is rotationally connected to the lamp base 1 through a hinge shaft. This structure is a commonly used lamp body structure and can achieve the orientation of the lamp post 2.

[0035] The present utility model is further configured such that the upper end of the lamp post 2 is provided with a through groove, and the upper end of the rotating ring 43 extends out from above through the through groove. As Figure 1 shown, the design of this structure enables the user to rotate the rotating ring 43 externally, thereby playing a role in adjusting the size of the light-emitting groove 411.

[0036] The present utility model is further configured such that a limiting member 5 is provided on the rotating ring 43. The design of this structure can prevent the rotating ring 43 from rotating non-artificially.

[0037] The present utility model is further configured such that the limiting member 5 includes a limiting bead 51, a limiting groove 52, and a limiting spring 53. The limiting groove 52 is provided on the rotating ring 43. One end of the limiting spring 53 is connected to the bottom of the limiting groove 52, and the other end abuts against the limiting bead 51;

[0038] A clamping groove is provided on the groove wall of the through groove. The limiting member 5 and the clamping groove are both provided with multiple groups at equal intervals along the circumferential direction of the rotating ring 43.

[0039] As Figure 2 and Figure 6 shown, through the cooperation of the limiting bead 51 and the clamping groove, the rotating ring 43 is initially limited. During the rotation of the rotating ring 43, a certain amount of torsional force needs to be applied to the rotating ring 43 to separate the limiting bead 51 from the clamping groove.

[0040] The present utility model is further configured such that multiple groups of friction blocks 6 are provided on the outer wall of the rotating ring 43. The design of this structure can increase the friction during rotation and facilitate the operator to rotate the rotating ring 43.

[0041] The present utility model is further configured such that multiple groups of light source assemblies 3 and light-shielding assemblies 4 are provided and are arranged in sequence along the length direction of the lamp post 2.

[0042] The light source assembly 3 includes a lamp board, lamp beads, etc.

[0043] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
