[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figure 1-Figure 3 As shown, a lamp holder connection structure includes a connector disposed on a lamp body 2 and a connector 3 disposed on a lamp holder 1. The connector 3 has a spherical recess structure 31. The connector is a sphere 4 adapted to the spherical recess structure 311. The inner diameter of the spherical recess structure 311 is larger than the diameter of the sphere 4, and the opening diameter of the spherical recess structure 311 is smaller than the diameter of the sphere 4. The connector is embedded in the spherical recess structure 311, and the lamp holder 1 rotates 360° relative to the lamp body 2. In this embodiment, the inner diameter of the spherical recess structure 311 is 20.5 mm, the diameter of the sphere 4 is 20 mm, and the opening diameter of the spherical recess structure 311 is 19 mm. Of course, in other embodiments, the dimensions of the three can be set to other values, as long as it ensures that the sphere 4 can enter the spherical recess structure 311 without falling off on its own. With this design, the sphere 4 can rotate 360° within the spherical recess structure 31 without detaching itself, and the lamp body 2 and lamp head 1 can be detachably connected, saving space and facilitating transportation.

[0023] In this embodiment, the connecting seat 3 is embedded in the lamp holder 1, and the shape of the outer side of the connecting seat 3 is the same as the shape of the outer side of the lamp holder 1 housing at its location. This arrangement ensures that the outer side of the connecting seat 3 fits the outer side of the lamp holder housing, guaranteeing the overall aesthetics of the lamp holder 1. In other embodiments, the outer side of the connecting seat 3 may protrude from the lamp holder 1 housing or be recessed relative to the lamp holder housing.

[0024] The connecting seat 3 includes a snap-fit ​​part 31 with a spherical recess structure 311. The snap-fit ​​part 31 is cylindrical in shape, and the spherical recess structure 311 extends from the upper end of the cylinder into its interior. A through hole 11 with the same outer peripheral contour as the open end of the spherical recess structure 31 is provided on the housing of the lamp head 1. The diameter of the through hole 11 is larger than the diameter of the open end of the spherical recess structure 31. A limiting part is provided on the outer peripheral side of the open end of the spherical recess structure 31. A support platform is provided on the inner side wall of the through hole 11. When the snap-fit ​​part 31 is inserted into the through hole 11, the limiting part is placed on the support platform, and the upper end face of the limiting part is located inside the outer side of the housing of the lamp head 1. The limiting part is an irregularly shaped limiting ring, and the limiting part and the snap-fit ​​part 31 are integrally formed. With this configuration, the lamp head 1 is first connected through the snap-fit ​​part 31, and then the ball 4 is inserted into the snap-fit ​​part 31, ultimately achieving a 360° rotatable connection between the lamp body 2 and the lamp head 1.

[0025] Multiple downward-extending notches (I) are provided circumferentially at intervals on the side wall of the latching part 31, and multiple sets of notches (II) are provided opposite to each other on the limiting part, dividing the limiting part into multiple arc-shaped blocks 32. The notches (I) on the limiting part and the notches (II) on the latching part 31 are opposite to and connected to each other. With this configuration, when the ball 4 is inserted into the spherical recess structure 311, the arc-shaped blocks 32 move outward due to the presence of the notches, making it easier for the ball 4 to be embedded into the spherical recess structure 311 and also easier to remove the ball 4 from the spherical recess structure 311.

[0026] The support platform includes multiple arc-shaped platforms 12, which are equally spaced circumferentially. The length of the arc-shaped strip 32 is greater than the interval between two adjacent arc-shaped platforms 12. A locking member 33 is provided on the outer wall of each arc-shaped strip 32. The locking member 33 has an L-shaped longitudinal section, with its vertical portion parallel to the central axis of the locking portion 31 and its horizontal portion extending away from the locking portion 31. The locking member 33 enters the lamp holder 1 from between two adjacent arc-shaped platforms 12 and engages with the inside of the lamp holder 1 housing. This arrangement, with the horizontal portion of the locking member 33 engaging with the inside of the lamp holder 1 housing, connects the connecting seat 3 to the lamp holder 1.

[0027] A lamp holder 1 includes a lamp holder housing, a lamp base, and a light source module disposed on the lamp base. The lamp base and the light source module are disposed inside the lamp holder housing. The lamp holder 1 also includes a connecting seat 3 disposed on the lamp holder housing. The connecting seat 3 is the connecting seat 3 in the lamp holder 1 connection structure described in this embodiment. The connecting seat 3 is connected to the lamp holder 1 using the lamp holder connection structure described in this embodiment.

[0028] A lighting fixture is a tree lamp with multiple lamp heads 1. The tree lamp includes a lamp body 2 and multiple lamp heads 1. The lamp body 2 has a main lamp post and multiple branch lamp posts. Connectors in the lamp head 1 connection structure described in this embodiment are provided at the ends of the multiple branch lamp posts. The lamp head 1 is the lamp head 1 described in this embodiment. The lamp body 2 and the lamp head 1 are connected by the lamp head connection structure described in this embodiment.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
