[0058] In the first embodiment, if Figure 5As shown, the upper end of the lamp holder 100 is provided with a support assembly 500. When the present invention is installed for lighting, the support assembly 500 is connected to the outside to achieve installation. When adjusting the lighting angle, the lamp holder 100 and the support assembly 500 are relatively rotated to achieve the change of the lighting angle. In actual application, the support assembly 500 has a variety of specific structural forms, such as a mounting ring hinged to the outer wall of the lamp holder 100, a mounting support spherically hinged to the outer wall of the lamp holder 100, etc. Its specific structural form can be set accordingly according to actual use needs, and those skilled in the art can understand that it is not limited here. The specific structural form of the support assembly 500 is not described in detail here, and will be described in detail below.

[0059] In some embodiments, the support assembly 500 includes a connecting ring 510 and a face ring 520. The connecting ring 510 is sleeved on the upper end of the lamp holder 100 and is hinged to the lamp holder 100. The face ring 520 is sleeved on the connecting ring 510. The outer wall of the connecting ring 510 is provided with a second hook 511. The inner wall of the face ring 520 is provided with a second annular groove 521 for the second hook 511 to be engaged. By providing a hinge connection between the connecting ring 510 and the lamp holder 100, and a rotatable engagement between the connecting ring 510 and the face ring 520, the lighting angle of the present invention has two different degrees of freedom for adjustment, which can enhance the adjustability of the lighting angle and improve its applicability.

[0060] In the first embodiment, if Figure 5 , Figure 6 and Figure 8 As shown, the support assembly 500 includes a face ring 520 and a connecting ring 510. The connecting ring 510 is sleeved on the upper end of the lamp holder 100, and the symmetrical two sides are hinged to the upper end of the lamp holder 100 by bolts, so that the connecting ring 510 can rotate perpendicular to the axis of the lamp holder 100. Figure 3 and Figure 4 As shown, the outer wall of the connecting ring 510 is provided with a second hook 511, and the inner wall of the face ring 520 is correspondingly provided with a second annular groove 521. The face ring 520 is connected to the connecting ring 510 through the cooperation of the second hook 511 and the second annular groove 521, so that the face ring 520 can rotate around the axis of the connecting ring 510, so that the lamp holder 100 can have two different degrees of rotational freedom relative to the face ring 520, and can achieve better lighting angle adjustment. In actual application, the face ring 520 and the connecting ring 510 can also be hinged, and the specific structural form of the support assembly 500 is not limited thereto, and it can be changed accordingly according to actual use needs, which can be understood by those skilled in the art.

[0061] In some embodiments, the connecting ring 510 is provided with a first rotation-limiting protrusion 512, and the face ring 520 is correspondingly provided with a second rotation-limiting protrusion 522 that can abut against the first rotation-limiting protrusion 512. By providing the first rotation-limiting protrusion 512 and the second rotation-limiting protrusion 522, when the connecting ring 510 rotates relative to the face ring 520, the first rotation-limiting protrusion 512 can abut against the second rotation-limiting protrusion 522 to limit the range of rotation of the connecting ring 510 relative to the face ring 520, thereby preventing the connecting ring 510 from continuously rotating in one direction at an excessively large angle and causing the wires on the lamp holder 100 to be entangled, thereby improving the safety of use.

[0062] In the first embodiment, if Figure 2 , Figure 3 and Figure 8 As shown, a first rotation-limiting protrusion 512 is provided on the outer wall of the connecting ring 510, and the first rotation-limiting protrusion 512 is located at the upper step of the connecting ring 510. A second rotation-limiting protrusion 522 is correspondingly provided on the upper end of the inner wall of the face ring 520. When the face ring 520 rotates to a certain angle relative to the connecting ring 510, the first rotation-limiting protrusion 512 abuts against the second rotation-limiting protrusion 522, and the face ring 520 is restricted from continuing to rotate relative to the connecting ring 510, so as to avoid the occurrence of wire entanglement. In actual application, the number and position of the first rotation-limiting protrusion 512 and the second rotation-limiting protrusion 522 can be set according to actual use needs. For example, two are set and symmetrically distributed. The specific structural form can be understood by those skilled in the art and is not limited here.

[0063] In some embodiments, the support assembly 500 further includes a mounting member 530, on which a plug-in end 531 is provided, on which a clamping portion 532 is provided, and on which an outer wall of the face ring 520 is provided a clamping slot 523 for inserting the plug-in end 531, on which a clamping hole 524 is provided, and in which the clamping portion 532 can be clamped. By inserting the plug-in end 531 into the clamping slot 523 and clamping the clamping portion 532 in the clamping hole 524, a detachable connection between the mounting member 530 and the face ring 520 is achieved, and the connection structure is easy to disassemble and assemble, and the mounting member 530 can be easily repaired and replaced.

[0064] In the first embodiment, if Figure 5 , Figure 6 and Figure 8As shown, an abutment protrusion 525 is provided in the groove of the snap-in slot 523. When the mounting member 530 is inserted into the snap-in slot 523 through the plug-in end 531, the clamping portion 532 is clamped in the clamping hole 524 to realize the connection between the mounting member 530 and the face ring 520. At the same time, the abutment protrusion 525 abuts against the end of the plug-in end 531, so that the plug-in end 531 is pressed against the inner wall of the snap-in slot 523, thereby improving the stability of the connection and avoiding looseness between the mounting member 530 and the face ring 520. The mounting member 530 used in this embodiment is a retaining spring clip, which can clamp the face ring 520 to the ceiling, thereby realizing the use and installation of the present invention. In actual application, there are many ways to connect the mounting member 530 and the face ring 520, such as connection by bolts, etc., and the specific structure of the mounting member 530 can also be set accordingly according to actual use needs, such as using snap fasteners, threaded connectors or other clamps, etc. The specific setting form of the mounting member 530 is not limited here, and can be understood by those skilled in the art.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
