[0021] Furthermore, the adapter 2 has a first connecting contact point 7 at one end embedded in the power mounting slot 5, and a second connecting contact point 8 electrically connected to the power module 4 is provided in the power mounting slot 5. When the adapter 2 is embedded in the power mounting slot 5, the external thread 31 and the internal thread 32 are threadedly connected to fix the power module 4 and the adapter 2, and the first connecting contact point 7 and the second connecting contact point 8 abut against each other to conduct electricity. When the power module 4 is installed on the adapter 2 on the lamp housing 1, electricity is conducted through the abutment of the first connecting contact point 7 and the second connecting contact point 8, directly realizing the electrical connection between the power module 4 and the adapter 2 without the need for external wires, making it more convenient to use and more aesthetically pleasing.

[0022] Furthermore, a detachable connection mechanism 9 is provided between the lamp housing 1 and the adapter 2 to detachably connect the adapter 2 and the lamp housing 1. The detachable connection mechanism 9 includes: an adapter positioning groove 91 recessed on the back of the lamp housing 1; an adapter positioning protrusion 92 disposed on the adapter 2 and matching the adapter positioning groove 91; a first connecting hole 93, with multiple first connecting holes 93 disposed around the adapter positioning groove 91; and a second connecting hole 94, with multiple second connecting holes 94 disposed circumferentially on the adapter 2 and corresponding to the first connecting holes 93. The adapter positioning protrusion 92, in conjunction with the adapter positioning groove 91, facilitates positioning and installation, and the bolts used to secure the connection to the first connecting holes 93 and the second connecting holes 94 ensure a stable connection.

[0023] In addition, the adapter 2 is provided with an adapter connection groove 10 at one end away from the adapter positioning protrusion 92, and a plurality of second connection holes 94 are provided on the adapter connection groove 10 in the circumferential direction.

[0024] Furthermore, it also includes a circuit board 11 located on the front of the lamp housing 1. The lamp housing 1 has a wiring hole 12 that communicates with the adapter positioning groove 91, and the adapter positioning protrusion 92 has a third contact point 13 corresponding to the wiring hole 12. One end of a wire is connected to the circuit board 11, and the other end passes through the wiring hole 12 and connects to the third contact point 13, realizing a concealed electrical connection, which is more aesthetically pleasing.

[0025] In addition, to improve the heat dissipation performance of the product, the back of the lamp housing 1 is provided with a plurality of heat dissipation fins 17 arranged circumferentially.

[0026] Specifically, the circuit board 11 is provided with a plurality of LED beads 18 arranged in a diffused manner, and the front of the lamp housing 1 is provided with a lamp cover 19 covering the LED beads 18.

[0027] More specifically, the connecting accessory 6 includes: a lower connecting cylinder 621 for connecting to the lamp housing 1; a connecting ring 622 disposed at the upper end of the lower connecting cylinder 621; a connecting rod 623, one end of which is detachably inserted into the connecting ring 622; a rod connecting mechanism 624 disposed between the connecting ring 622 and the connecting rod 623 for detachably connecting the connecting ring 622 and the connecting rod 623; an upper connecting cylinder 625, one end of which is detachably connected to the lower connecting cylinder 621, and the other end of which is used to connect to the ceiling, wherein the lower end of the upper connecting cylinder 625 is provided with a clearance hole 626 for the connecting ring 622 to pass through; and a cylinder connecting mechanism 627 disposed between the lower connecting cylinder 621 and the upper connecting cylinder 625 for detachably connecting the lower connecting cylinder 621 and the upper connecting cylinder 625. Consumers can choose to insert the connecting rod into the connecting protrusion ring and connect it to the ceiling-mounted wire to achieve a ceiling-mounted installation of the ceiling light, depending on their actual usage. Alternatively, they can disassemble the connecting rod and detachably connect the upper and lower connecting tubes, connecting the upper connecting tube to the ceiling to achieve a ceiling-mounted installation of the ceiling light, thus meeting their usage needs.

[0028] Further, the cylinder connecting mechanism 627 includes: a first extending protrusion 6271, at least two first extending protrusions 6271 arranged circumferentially on the periphery of the connecting ring 622; a first retaining groove 6272, which is disposed circumferentially on the first extending protrusion 6271 along the connecting ring 622; a first slot 6273, at least two first slots 6273 arranged circumferentially on the periphery of the clearance hole 626 and corresponding to the first extending protrusion 6271; and a first retaining protrusion 6274, which extends along the groove wall of the first slot 6273. When the first extending protrusion 6271 extends into the first slot 6273, the lower connecting cylinder 621 can rotate relative to the upper connecting cylinder 625 until the first retaining protrusion 6274 enters the first retaining groove 6272, thereby restricting the lower connecting cylinder 621 from moving axially relative to the upper connecting cylinder 625 along the connecting ring 622. The rotational retaining mechanism facilitates easy assembly and disassembly.

[0029] Specifically, the cylinder connecting mechanism 627 further includes: a first latch 6275, at least two first latches 6275 arranged circumferentially around the connecting protrusion 622; and a first latch groove 6276, at least two first latch grooves 6276 arranged circumferentially around the clearance hole 626 and corresponding to the first latches 6275. When the lower connecting cylinder 621 rotates relative to the upper connecting cylinder 625 until the first latching protrusion 6274 enters the first latch groove 6272, the first latches 6275 latch and the corresponding first latch groove 6276 engage to restrict the rotation of the lower connecting cylinder 621 relative to the upper connecting cylinder 625. This makes the connection between the lower connecting cylinder 621 and the upper connecting cylinder 625 more stable. When it is necessary to separate the lower connecting cylinder 621 and the upper connecting cylinder 625, it is only necessary to apply a force to the upper connecting cylinder 625 relative to the lower connecting cylinder 621 to rotate it, causing the first latches 6275 to deform and disengage from the first latch grooves 6276.

[0030] More specifically, the cylinder connecting mechanism 627 further includes: a lower cylinder connecting hole 6277, at least two of which are circumferentially arranged around the connecting protrusion 622; and an upper cylinder connecting hole 6278, at least two of which are circumferentially arranged around the clearance hole 626 and correspond to the lower cylinder connecting hole 6277. When the lower connecting cylinder 621 rotates relative to the upper connecting cylinder 625 until the first locking protrusion 6274 enters the first locking groove 6272, the upper cylinder connecting hole 6278 aligns with the lower cylinder connecting hole 6277. A pin then passes through the upper cylinder connecting hole 6278 and the lower cylinder connecting hole 6277 to further secure the connection.

[0031] In addition, the boom connecting mechanism 624 includes a first boom connecting hole 6241 that passes through the connecting protrusion 622 radially, and a second boom connecting hole 6242 that passes through the boom 623 radially. When the boom 623 is inserted into the connecting protrusion 622, the boom 623 can rotate relative to the connecting protrusion 622 until the first boom connecting hole 6241 is opposite to the second boom connecting hole 6242.

[0032] Furthermore, the upper connecting cylinder 625 includes a cylinder body 6251, a top connecting plate 6252 detachably disposed at the upper end of the cylinder body 6251 for connection with the ceiling, and a top plate connecting mechanism 6253 for detachably connecting the cylinder body 6251 and the top connecting plate 6252. The connecting protrusion 622 extends into the cylinder body 6251 through the clearance hole 626. When hoisting installation is required, the entire upper connecting cylinder 625 can be disassembled, or only the top connecting plate 6252 can be disassembled, and the connecting rod 623 can be inserted into the cylinder body 6251 and inserted into the connecting protrusion 622 without disassembling the connecting cylinder 621 and the cylinder body 6251, making it more convenient to use.

[0033] Furthermore, the top plate connecting mechanism 6253 includes: a second extending protrusion 62531, at least two of which are circumferentially disposed on the edge of the top connecting plate 6252; a second slot 62532, which is circumferentially disposed on the second extending protrusion 62531; and a second locking protrusion 62533, which extends radially along the inner wall of the cylinder 6251. When the top connecting plate 6252 is embedded in the cylinder 6251, the top connecting plate 6252 can rotate relative to the cylinder 6251 until the second locking protrusion 62533 enters the second slot 62532, thereby restricting the axial movement of the top connecting plate 6252 relative to the cylinder 6251. The rotational locking connection method is convenient to operate.

[0034] Specifically, the top plate connecting mechanism 6253 further includes: a third extending protrusion 62534, which is located on the side of the second extending protrusion 62531 away from the top connecting plate 6252; a first top plate connecting hole 62535, which radially penetrates the third extending protrusion 62534; and a second top plate connecting hole 62536, which radially penetrates the cylinder 6251. When the top connecting plate 6252 rotates relative to the cylinder 6251 until the second locking protrusion 62533 enters the second locking groove 62532, the first top plate connecting hole 62535 and the second top plate connecting hole 62536 are opposite each other, and a pin or other pin is used to pass through the first top plate connecting hole 62535 and the second top plate connecting hole 62536, so that the cylinder 6251 and the top connecting plate 6252 are firmly connected.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
