[0029] The outside of the base 10 can be designed with mounting holes or fixing devices to facilitate the installation of the downlight 100 on the ceiling or other mounting surfaces. At the same time, the fixing methods of the power supply module 20 and the light-emitting module 30 in their respective cavities are also stable and reliable, preventing loosening or damage due to vibration or external force.

[0030] Based on the above technical solution, the downlight 100 in this embodiment adopts an in-built power supply design. By directly integrating the power module 20 into the base 10 of the downlight 100, the overall space occupation and installation area of the downlight 100 are reduced, the installation steps are simplified, and the aesthetics are improved.

[0031] In some embodiments, as Figure 1 and Figure 2 shown, the base 10 includes a first housing 13 and a second housing 14. The bottom plate of the first housing 13 forms a gap with the bottom plate of the second housing 14. A first cavity 11 is provided in the first housing 13, and a second cavity 12 is provided in the second housing 14.

[0032] Specifically, the internal space of the first housing 13 constitutes the first cavity 11, and the internal space of the second housing 14 constitutes the second cavity 12. The first housing 13 and the second housing 14 are of a semi-closed structure. The upper edge of the second housing 14 is provided with a connection structure matching the first housing 13, such as a buckle, a threaded hole or a slot, etc., to achieve a tight docking between the two. In addition, the bottom surface of the first housing 13 can also serve as the installation surface of the entire downlight 100, and installation holes or fixing devices can be designed thereon to be fixed to the ceiling or other installation surfaces.

[0033] During the assembly process, first, the power module 20 is installed in the first cavity 11 of the first housing 13 and ensured to be firmly fixed. Subsequently, the second housing 14 is aligned with the first housing 13, and the two are combined together through the corresponding connection structure. At this time, a gap is formed between the bottom plate of the first housing 13 and the bottom plate of the second housing 14 to respectively accommodate the power module 20 and the light-emitting module 30.

[0034] In some embodiments, the first housing 13 is provided with a first fastener, and the power module 20 is provided with a second fastener. The first fastener and the second fastener are detachably connected.

[0035] Specifically, a first fastener (not shown in the figure) is provided on the inner wall or the bottom plate of the first housing 13, and a second fastener matching it is provided at the corresponding position of the power module 20. The first fastener and the second fastener adopt a threaded connection, a snap connection, a magnetic attraction connection or other detachable connection methods to ensure that the power module 20 can be firmly installed in the first cavity 11 and can be disassembled when needed.

[0036] Exemplarily, four threaded holes are evenly distributed on the bottom plate of the first housing 13 as the first fasteners. These four threaded holes are arranged at intervals around the installation position of the power module 20 to ensure that the power module 20 can be kept horizontal and stable after installation. Four threaded holes corresponding to the threaded holes on the first housing 13 are designed on the edge of the power module 20 as the second fasteners.

[0037] In some embodiments, guide grooves or positioning holes (not shown in the figures) are further provided around the power supply module 20 to facilitate matching with the guiding structure in the first housing 13 during the installation process, ensuring the accuracy and convenience of installation.

[0038] In some embodiments, such as Figure 4 shown, fixing posts 15 are provided at the bottom of the first housing 13. The fixing posts 15 are provided with first mounting holes 16, and the power supply module 20 is provided with second mounting holes 17. The first mounting holes 16 and the second mounting holes 17 are fastened by screws.

[0039] Specifically, one or more fixing posts 15 are provided at the bottom of the first housing 13. The fixing posts 15 are arranged perpendicular or approximately perpendicular to the bottom plane of the first housing 13. Each fixing post 15 is provided with a first mounting hole 16. The first mounting holes 16 are used to correspond to the second mounting holes 17 on the power supply module 20 one by one. The first mounting holes 16 and the second mounting holes 17 are internal threaded holes for cooperating with screws to achieve a fastening connection.

[0040] In some embodiments, slots or mounting positions matching the fixing posts 15 are provided at the bottom or side of the power supply module 20 to be able to position the power supply module 20 on the first housing 13.

[0041] In some embodiments, such as Figure 4 shown, the first housing 13 includes an upper housing 131 and a lower housing 132. The upper housing 131 covers the opening of the lower housing 132 to form a first cavity 11.

[0042] Specifically, the first housing 13 is a detachable housing structure. The power supply module 20 is fixed inside the lower housing 132, and the upper housing 131 is covered on the opening of the lower housing 132.

[0043] In some embodiments, the light-emitting module 30 can rotate relative to the second housing 14.

[0044] Specifically, the light-emitting module 30 can be connected to the second housing 14 through a rotating shaft. The rotating shaft is arranged at the connection between the light-emitting module 30 and the second housing 14 to enable the light-emitting module 30 to rotate around the rotating shaft. In order to limit the rotation angle of the light-emitting module 30, a limiting structure, such as a limiting block, can be arranged on the rotating shaft. In addition, for easy operation, control components, such as an adjusting handle or a knob, can also be arranged on the light-emitting module 30 to manually adjust the rotation angle of the light-emitting module 30 to achieve directional lighting.

[0045] Exemplarily, the light-emitting module 30 can be rotated integrally to 60 degrees and 38 degrees, so that the lens of the light-emitting module 30 emits light outward from these two light-emitting angles of 60 degrees and 38 degrees.

[0046] In some embodiments, a ring cover 40 is provided on one side of the second shell 14 away from the first shell 13 . The ring cover 40 covers the lens of the light emitting module 30 . The ring cover 40 can be replaced with multiple colors so that the light emitting module 30 can present different colors of light.

[0047] Second, as Figure 5 and Figure 6 As shown, an embodiment of the utility model provides a lighting system, which includes a junction box 200 and a downlight 100. The junction box 200 is provided with a connection terminal 21. The power module 20 in the downlight 100 is connected to the connection terminal 21 in the junction box 200 through an electrical connection line 22.

[0048] Specifically, the junction box 200 is also called a quick-connect junction box, which is made of fireproof and waterproof materials and has sufficient strength and durability. In order to save the steps of applying glue, the junction box 200 is usually used to achieve quick wiring. Three wiring terminals 21 are provided inside the box body of the junction box 200, which are respectively used to connect the live wire, the neutral wire and the ground wire. Each wiring terminal 21 is provided with a screw hole for fixing the terminal of the electrical connection wire 22.

[0049] The electrical connection line 22 is used to transmit power from the junction box 200 to the downlight power module 20. The junction box 200 serves as a centralized point for power input and receives power from an external power source through the connection terminals 21 inside it. The light-emitting module 30 of the downlight 100 requires a stable power supply to operate normally, and this power supply is provided by the power module 20. Therefore, the electrical connection line 22 enables power to be transmitted from the junction box 200 to the inside of the downlight 100. During installation, one end of the electrical connection line 22 is connected to the connection terminal 21 of the junction box 200, and the other end is connected to the power module 20 of the downlight 100 to complete the electrical connection.

[0050] In some embodiments, Figure 5 and Figure 6 As shown, the junction box 200 is provided with a wire outlet 23 connected to an external wire, and the size of the wire outlet 23 is adjustable to clamp the external wire.

[0051] Specifically, the junction box 200 mainly includes a box body and a terminal block 21. The box body is used to accommodate and protect the internal electrical components; the terminal block 21 is arranged in the box body for electrically connecting with the external wires; and the wire outlet 23 is arranged on the side wall of the box body for guiding the external wires into the box body and connecting with the terminal block 21. During the installation process, the size of the wire outlet 23 is adjusted according to the size of the external wires, so that the wire outlet 23 tightly clamps the wires to achieve a stable connection.

[0052] In some embodiments, Figure 6As shown, the junction box 200 includes an upper cover 24 and a lower cover 25. Part of the wire outlet 23 is provided on the upper cover 24, and the remaining part of the wire outlet 23 is provided on the lower cover 25. The upper cover 24 is covered on the lower cover 25.

[0053] Specifically, the box body of the junction box 200 includes an upper cover 24 and a lower cover 25. The upper cover 24 and the lower cover 25 can be connected together by snap fasteners, screws or other fastening means to form a sealed box body. The terminal block 21 is arranged inside the lower cover 25 and is used for electrical connection with external wires. The wire outlet 23 is partially located on the upper cover 24 and partially located on the lower cover 25, and the two cooperate with each other to form a complete wire outlet channel.

[0054] In some embodiments, one of the upper cover 24 and the lower cover 25 is provided with a clamping member 26, and the other of the upper cover 24 and the lower cover 25 is provided with a clamping port 27. The clamping member 26 is snapped into the clamping port 27 to adjust the size of the wire outlet 23.

[0055] Exemplarily, as Figure 6 shown, a clamping member 26 is provided on each side of the upper cover 24, and clamping teeth are provided on its clamping surface. Correspondingly, clamping ports 27 matching the clamping members 26 are provided on each side of the lower cover 25. The shape and size of the clamping ports 27 are designed such that the clamping members 26 can be snapped into and fixed. As the clamping teeth of the clamping member 26 move within the clamping port 27, a part of the lower cover 25 undergoes a slight displacement accordingly, thereby changing the opening size of the wire outlet 23 and further clamping the external wire.
