Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] A desk lamp is a lighting device placed on a table for reading, studying, working, and other activities. To meet the need for adjustable illumination angles, existing desk lamps generally include a base, a support rod, and a lamp head. The lamp head is pivotally hinged to the top of the support rod, allowing for initial vertical adjustment of the lamp head's illumination angle. The bottom of the support rod is pivotally hinged to the base, enabling further adjustment of the overall illumination angle. However, because the pivotal hinge at the bottom of the support rod only allows for vertical adjustment, it limits the adjustable angle of the support rod and fails to meet the need for multi-angle adjustment.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a desk lamp with adjustable illumination angle, comprising: a lamp head assembly 10, a support rod 20, a first double-ended screw 30, an angle adjustment ball 40, and a base 50. The top of the base 50 is recessed inward to form an angle adjustment ball groove 51. A magnet 52 is provided in the base 50 at a position corresponding to the angle adjustment ball groove 51. One side of the angle adjustment ball 40 is fixed to one end of the support rod 20 by the first double-ended screw 30. The other side of the angle adjustment ball 40 is embedded in the angle adjustment ball groove 51 and is magnetically attracted and slidably connected to the magnet 52, so that the angle adjustment ball 40 can rotate along the angle adjustment ball groove 51. The lamp head assembly 10 is installed at the other end of the support rod 20 and moves together with the support rod 20.

[0031] In this utility model, the above-mentioned solution is adopted so that the support rod 20 is magnetically and slidably connected to the base 50 through the angle adjustment ball 40, thereby supporting the 360° horizontal rotation and 80° conical deflection of the support rod 20. This overcomes the problem that in traditional table lamps, the support rod 20 can only rotate vertically after its bottom is pivotally hinged to the base 50, and cannot be adjusted in multiple angles. This improves the range of adjustment angle of the support rod 20 in the product of this application, meeting people's needs for multi-angle adjustment of the support rod 20.

[0032] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in order to assemble the base 50, the base 50 includes: a base body 53, a base cover 54, and a plurality of magnets 52; the top of the base body 53 is recessed inward to form the angle adjustment ball groove 51, the angle adjustment ball groove 51 is recessed inward to form a plurality of mounting grooves 511, the plurality of magnets 52 are embedded in the corresponding mounting grooves 511, and the base cover 54 is attached to the surface of the angle adjustment ball groove 51 to seal the plurality of magnets 52 in the corresponding mounting grooves 511.

[0033] To increase the magnetic attraction stability of the angle adjustment ball 40, the bottom surfaces of the multiple mounting slots 511 are parallel to the corresponding positions of the base cover 54. This ensures that after the multiple magnets 52 are installed in the corresponding mounting slots 511, the upper surfaces of the multiple magnets 52 are parallel to the corresponding positions of the base cover 54. This reduces the distance between the magnets 52 and the base cover 54, and further reduces the distance between the magnets 52 and the angle adjustment ball 40, thereby increasing the magnetic attraction stability between the magnets 52 and the angle adjustment ball 40.

[0034] To fix the angle adjustment ball 40, one end of the first double-ended screw 30 is inserted into one side of the angle adjustment ball 40 for fixation, and the other end of the first double-ended screw 30 is inserted into one end of the support rod 20 for fixation, thereby fixing one side of the angle adjustment ball 40 to one end of the support rod 20.

[0035] To assemble the support rod 20, the support rod 20 includes: a support rod body 21 and a handle 22; the handle 22 includes: two free ends 221 and a grip portion 222 connecting the two free ends 221. The two free ends 221 are respectively fixed to the support rod body 21. The grip portion 222 is used to manually lift the table lamp with multi-angle adjustable illumination angle. In this utility model, the handle 22 is "U" shaped, which increases the aesthetics of the table lamp and makes it convenient for the user to hold. It is not limited to this utility model. The handle 22 can also be semi-circular, S-shaped, etc. The handle 22 only needs to be convenient for the user to hold. This utility model does not limit it in this way.

The light-transmitting panel 13 is installed at the light outlet 111. The light emitted by the LED light source board 12 passes through the light-transmitting panel 13 and is emitted to the outside.

[0037] To install the LED light source board 12, the lamp head assembly 10 further includes: a second double-ended screw 14 and a light source mounting bracket 15; the second double-ended screw 14 passes through one end of the light source mounting bracket 15 and extends into the inner wall of the lamp cover 11, and fixing bolts 16 are screwed into both ends of the second double-ended screw 14, thereby fixing the light source mounting bracket 15 inside the lamp cover 11; the LED light source board 12 is installed at the other end of the light source mounting bracket 15, thereby installing the LED light source board 12 inside the lamp cover 11 through the light source mounting bracket 15.

[0038] In order to supply power to the LED light source board 12, the second double-headed screw 14 is provided with a through hole 141, which connects the support rod 20 and the inner space of the lamp cover 11; the power line from the support rod 20 passes through the through hole 141 and extends into the lamp cover 11 to be electrically connected to the LED light source board 12, thereby supplying power to the LED light source board 12.

[0039] In order to install the light-transmitting panel 13, the lampshade 11 is bent inward at the light outlet 111 to form a fixed rolled edge 112. The outer edge of the light-transmitting panel 13 is directly fixed to the fixed rolled edge 112, thereby fixing the light-transmitting panel 13 at the light outlet 111. The installation of the light-transmitting panel 13 has the advantages of simple structure, convenient installation, low cost, uniform brightness and good light efficiency.

[0040] In this utility model, the lampshade 11 is preferably trumpet-shaped, but it is not limited to this utility model. The lampshade 11 can also be hemispherical, cuboid, cube or cone-shaped. The shape of the lampshade 11 can serve to fix the LED light source board 12 and improve the aesthetics of the lamp head assembly 10. This utility model does not limit this.

[0041] The present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments can be made without departing from the principles and spirit of the present invention, and these changes still fall within the protection scope of the present invention.
