In the present embodiment, the lamp holder 100 may be detachably connected to the rotating base 221, or the lamp holder 100 may be detachably connected to the fixing member 230.

In an alternative embodiment, the outer peripheral surface of the fixing member 230 is provided with a first plugging portion 231, the inner peripheral surface of the lamp post 220 is provided with a second plugging portion, the first plugging portion 231 and the second plugging portion are plugged and matched in the axial direction of the lamp post 220, and the first plugging portion 231 and the second plugging portion extend along the plugging direction. Of course, the fixing member 230 may also be disposed in the lamp post 220 by a threaded connection, a clamping connection, or the like. Alternatively, the first plugging portion 231 may be a plugging protrusion or a plugging groove, and the second plugging portion may be a plugging groove or a plugging protrusion.

In this embodiment, the outer peripheral surface of the fixing member 230 is provided with a first plugging portion 231, the inner peripheral surface of the lamp post 220 is provided with a second plugging portion, the first plugging portion 231 and the second plugging portion extend along the axial direction of the lamp post 220, the fixing member 230 is inserted into the lamp post 220 along the axial direction of the lamp post 220 to connect the fixing member 230 with the lamp post 220, and the fixing member 230 is pulled along the axial direction of the lamp post 220 to separate the fixing member 230 from the lamp post 220. It can be seen that, with the structure of this embodiment, the fixing member 230 can be connected to or separated from the lamp post 220 by a simple plugging operation.

In an alternative embodiment, the lamp socket 100 is provided with the protrusion 120, and when the lamp body 200 is connected to the lamp socket 100, a portion of the lamp body 200 is sleeved outside the protrusion 120, and a portion of the inner circumferential surface of the lamp body 200 is fitted to the outer circumferential surface of the protrusion 120. If the lamp holder 100 is not provided with the protruding portion 120, the lamp body 200 is easy to topple over along the direction perpendicular to the axial direction of the lamp body 200 under the action of external force, but the lamp holder 100 of this embodiment is provided with the protruding portion 120, after the lamp body 200 is mounted on the lamp holder 100, a part of the lamp body 200 is sleeved outside the protruding portion 120 and is attached to the protruding portion 120, so that the protruding portion 120 can limit the lamp body 200 along the direction perpendicular to the axial direction of the lamp body 200, thereby preventing the lamp body 200 from toppling over along the direction perpendicular to the axial direction of the lamp body 200, and further improving the stability of the desk lamp.

Further, the boss 120 is in a limit fit with the lamp body 200 in the circumferential direction of the boss 120. Thus, the lamp body 200 is prevented from rotating around the axis thereof after being sleeved outside the protruding portion 120, and the first electrical connection portion 210 is prevented from moving relative to the second electrical connection portion 110 after being electrically contacted with the second electrical connection portion 110, so as to be out of contact with the second electrical connection portion 110.

Optionally, the protruding portion 120 may be in a form of a limit fit with the light body 200, for example: the cross section of the boss 120 is polygonal, such as triangular, rectangular, pentagonal, etc. In this embodiment, taking the cross section of the protruding portion 120 as an example, part of the inner peripheral surface of the lamp body 200 is attached to the protruding portion 120, so that the cross section of the inner cavity of the lamp body 200 and the protruding portion 120 is also rectangular, and thus the protruding portion 120 can limit the circumference of the lamp body 200. In addition, a limit structure can be additionally added between the protruding portion 120 and the lamp body 200 to realize limit fit between the protruding portion 120 and the lamp body 200 in the circumferential direction of the protruding portion 120.

In order to further improve the stability of the desk lamp, in an alternative embodiment, the lamp socket 100 is further provided with a mounting groove 130, at least a portion of the boss 120 is disposed in the mounting groove 130, an annular groove is formed between the outer peripheral surface of the boss 120 and the inner wall of the mounting groove 130, and when the lamp body 200 is connected to the lamp socket 100, a portion of the lamp body 200 is not disposed in the annular groove, that is, the lamp body 200 is disposed between the inner wall of the mounting groove 130 and the outer peripheral surface of the boss 120, and a portion of the outer peripheral surface of the lamp body 200 is attached to the inner wall of the mounting groove 130. In this embodiment, the lamp holder 100 is further provided with a mounting groove 130, at least a portion of the protruding portion 120 is disposed in an annular groove formed between the mounting groove 130 and the protruding portion 120, and a portion of the outer circumferential surface of the lamp body 200 is attached to an inner wall of the mounting groove 130, so that the inner wall of the mounting groove 130 can limit the lamp body 200 in a direction perpendicular to the axial direction of the lamp body 200, thereby further preventing the lamp body 200 from tilting in the direction perpendicular to the axial direction of the lamp body 200, and further improving the stability of the desk lamp.

Alternatively, the lamp body 200 and the lamp holder 100 may be connected by plugging, clamping, or the like, but the plugging and clamping have low connection strength, so that the lamp body 200 and the lamp holder 100 are easily separated. In an alternative embodiment, the desk lamp further includes a first screw coupling member 300, wherein a first coupling protrusion is provided in the lamp body 200, and one end of the first screw coupling member 300 passes through a surface of the lamp base 100 facing away from the protrusion 120 and is screw-coupled with the first coupling protrusion in order to fix the lamp body 200 to the lamp base 100 when the lamp body 200 is coupled with the lamp base 100. In this embodiment, the first connecting protrusion in the lamp body 200 is connected with the lamp socket 100 through the first threaded connection member 300, that is, the lamp body 200 is connected with the lamp socket 100 by adopting a threaded connection manner, and compared with plugging and clamping, the connecting strength of the threaded connection is higher, so that the risk of separating the lamp body 200 from the lamp socket 100 can be reduced.

Optionally, a gold plating layer is provided on the contacts to prevent oxidation of the contacts and affect the contact effect.

In this embodiment, the contact points of the electrical contact plate face the opening 122 of the accommodating space 121 and are opposite to the opening 122, and in the case that the lamp socket 100 is connected with the lamp body 200, one end of the first electrical connection part 210 may pass through the opening 122 and electrically contact the contact points of the electrical contact plate, thereby achieving the electrical connection of the lamp socket 100 with the lamp body 200. And the electrical contact plate is located in the receiving space 121 of the boss 120, that is, the electrical contact plate is wrapped by the boss 120, so that the boss 120 can protect the electrical contact plate from being damaged; in addition, the electrical contact plate disposed within the boss 120 may also reduce the electrical contact plate occupying installation space outside of the boss 120 as compared to an electrical contact plate disposed outside of the boss 120.

The electrical contact plate may be connected to the boss 120 by a clamping connection or a mode, but the connection strength of the clamping connection is not high, so that the electrical contact plate is easy to separate from the boss 120, and therefore, in an alternative embodiment, the desk lamp further includes a second threaded connection member 400, a second connection protrusion 123 is further disposed on a surface of the boss 120 facing away from the lamp socket 100, and one end of the second threaded connection member 400 penetrates the electrical contact plate and is in threaded connection with the second connection protrusion 123, so as to fix the electrical contact plate to the second connection protrusion 123. In this embodiment, the electrical contact plate is connected to the protruding portion 120 by the second threaded connection 400, that is, the electrical contact plate is connected to the protruding portion 120 by threaded connection, so that the risk of separating the electrical contact plate from the protruding portion 120 can be reduced due to higher connection strength of the threaded connection compared to the clamping connection; in addition, the boss 120 is further provided with a second connection protrusion 123, and one end of the second threaded connection member 400 passes through the electrical contact plate and a portion of the boss 120 except for the second connection protrusion 123 is in threaded connection with the second connection protrusion 123, so that the screwing length between the second threaded connection member 400 and the boss 120 can be increased, the connection strength between the second threaded connection member 400 and the boss 120 can be increased, and the risk of separating the electrical contact plate from the boss 120 can be further reduced.
