[0002] In the current lighting equipment manufacturing industry, downlights, as a widely used lighting product, are gradually moving towards a high degree of automation and intelligence in their production process. However, although automation technology has been widely applied in the assembly and testing of downlights, many challenges remain in the wire threading and soldering steps. In particular, the separation and guiding of the wires is especially difficult due to the flexibility of the wires and the small size of the threading holes, making automated wire threading and soldering particularly challenging.

[0003] Traditional downlight wiring methods mostly rely on manual operation. Workers need to manually thread the wires through the holes and accurately place them on the corresponding pads before soldering. This method is not only inefficient but also carries significant quality risks. It is difficult to maintain the stability and accuracy of the wires during the wiring process, leading to problems such as wire misalignment and poor soldering, which increases the difficulty of automated production.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0041] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0042] Example 1:

[0043] Please see Figures 1-2 As shown, the lamp 100 of this utility model includes a housing assembly 200 and a light source assembly 400 disposed inside the housing assembly 200. The lamp 100 has a branching structure 220 designed inside the housing assembly 200. After the main conductor 300 enters the housing assembly 200, it is automatically separated by the branching structure 220 and guided to the corresponding welding point 4102, achieving automated welding without the need for manual wire threading, effectively improving work efficiency.

[0044] Please see Figure 3 As shown, the housing assembly 200 includes a main body 210 and a branch structure 220.

[0045] The main body 210 includes a bottom wall 2101 and a side wall 2102. The side wall 2102 surrounds the bottom wall 2101, and the bottom wall 2101 and side wall 2102 together form a mounting cavity 2103. In this embodiment, the bottom wall 2101 and side wall 2102 are integrally formed. This increases the overall strength of the main body 210 and reduces assembly steps.

[0046] The main body 210 includes a wire-passing port 2104 that communicates with the mounting cavity 2103. The wire-passing port 2104 can be located on either the side wall 2102 or the bottom wall 2101. It only serves to facilitate the introduction and management of wires, and its specific location is not limited.

[0047] In this embodiment, please refer to Figure 6 As shown, both the bottom wall and the side wall can be provided with abutment portions 2105 extending towards the wire passage opening. Specifically, the side wall 2102 is provided with a first abutment portion 2151 extending towards the wire passage opening 2104, and the bottom wall 2101 is provided with a second abutment portion 2152 extending towards the wire passage opening 2104. After the main conductor 300 enters the mounting cavity 2103 through the wire passage opening 2104, it simultaneously abuts against the first abutment portion 2151 and the second abutment portion 2152, which provides a preliminary fixing effect on the main conductor 300, preventing it from sliding or falling off during installation and ensuring a stable and reliable conductor connection. Of course, in other embodiments, only the first abutment portion 2151 or only the second abutment portion 2152 can be provided, which can also provide a certain fixing effect.

[0048] Furthermore, both the bottom wall 2101 and the side wall 2102 can be provided with anti-pull teeth 2106 extending towards the wire insertion port 2104. In this embodiment, the anti-pull teeth 2106 are not shown, but they can be provided on the first abutment portion 2151 and the second abutment portion 2152. The provision of the anti-pull teeth 2106 further enhances the fixing effect and anti-pull performance between the main conductor 300 and the housing assembly 200.

[0049] The branch structure 220 is disposed in the mounting cavity 2103 and is disposed corresponding to the wire insertion port 2104.

[0050] Please see Figure 4 As shown, the branching structure 220 includes a head 2201 facing the wire inlet 2104 and several guide portions 2202 connected to the head 2201. The branching structure 220 can effectively separate the main conductor 300 into several branch conductors 310 through the head 2201, and guide the separated branch conductors 310 through the guide portions 2202. This simplifies conductor management and improves the neatness and efficiency of conductor layout.

[0051] The branching structure 220 includes a head 2201 and two supporting arms 2203 extending from the head 2201 at an included angle. In this embodiment, the guide portion 2202 is a guide surface. Specifically, the branching structure 220 has a triangular structure, with the head 2201 set at an acute angle and the two supporting arms 2203 also set at acute angles. Each supporting arm 2203 includes a guide surface. The main conductor 300 contacts the acute-angled head 2201 and is separated into two branch conductors 310, which are then guided along the guide surface. This design is simple and can effectively separate the main conductor 300 into two branch conductors 310 and guide them. In other embodiments, the two supporting arms 2203 can also be set at an obtuse angle, in which case a pointed tip is provided at the head 2201 to separate the main conductor 300 into two branch conductors 310.

[0052] In another embodiment, the guide portion 2202 is a guide channel (not shown). Specifically, the branch structure 220 includes a head 2201 and several guide channels arranged at an angle to the center extension line of the head 2201. The head 2201 can be configured to protrude from the tip of the guide channel. After the main conductor 300 contacts the tip, it is separated into two branch conductors 310, and the branch conductors 310 enter their respective guide channels. The guide channel, as the guide portion 2202, guides the branch conductors 310. The diameter of the guide channel is greater than or equal to the diameter of the branch conductor 310, ensuring that the conductors can enter smoothly and be guided. This design provides greater flexibility and adaptability, allowing for the setting of different numbers and directions of guide channels as needed.

[0053] In other embodiments, the main conductor 300 may also include three branch conductors 310, with the guide portion 2202 guiding the three branch conductors 310. The head 2201 is designed as two close, acute-angled tips, forming a wire passage between the two tips. After the main conductor 300 contacts the two tips, it is separated into three branch conductors 310, which enter from the middle wire passage and from both sides of the wire passage. The middle branch conductor 310 passes through the wire passage between the two tips. When the guide portion 2202 is a guide surface, the other two branch conductors 310 are guided along the guide surfaces on both sides. When the guide portion 2202 is a guide channel, the other two branch conductors 310 enter the guide channels on both sides. Of course, the branching structure can also divide the main conductor 300 into four or more branch conductors 310, which will not be elaborated here.

[0054] The branch structure 220 also includes a tail portion 2204 disposed opposite to the head portion 2201. The tail portion 2204 is provided with a groove 2241. The groove 2241 helps to disperse stress, enhance the strength and stability of the branch structure 220, and prevent damage caused by wire pulling or thermal expansion and contraction of the material itself.

[0055] Please see Figure 5 As shown, the light source assembly 400 is disposed within the mounting cavity 2103 of the housing assembly 200.

[0056] The light source assembly 400 includes a light source plate 410. The light source plate 410 has a positioning groove 4101 at the position corresponding to the wiring structure 220. The positioning groove 4101 ensures the precise positioning of the light source plate 410 and the wiring structure 220, improving the overall performance and stability of the lamp 100.

[0057] Furthermore, there are several hot melt pillars 2111 on the bottom wall 2101. The light source plate 410 has openings (not shown) corresponding to the positions of the hot melt pillars 2111. After the light source plate 410 is placed into the mounting cavity 2103, the openings are aligned with the hot melt pillars 2111. The hot melt pillars 2111 are melted by hot pressing to firmly fix the light source plate 410 on the bottom wall 2101.

[0058] The light source board 410 has several solder points 4102. These solder points 4102 are all located near the positioning groove 4101 and on the extension lines of the guide portion 2202, facilitating rapid connection between the wires and the light source assembly 400, thus improving assembly efficiency and reliability. In this embodiment, the light source board 410 has two solder points 4102. The main wire 300 is separated into two branch wires 310 by the branch structure 220, and then guided by the guide surface to the corresponding two solder points 4102 for soldering.

[0059] The luminaire 100 also includes a lampshade 500. The main body 210 is designed with ultrasonic welding lines, and the lampshade 500 is ultrasonically welded to the main body 210 to cover the mounting cavity 2103.

[0060] Please see Figures 6-7 As shown, the lamp 100 also includes a wire clamp 600 that covers the wire insertion port 2104. The main body 210 has a locking edge 2107 at the wire insertion port 2104. The wire clamp 600 includes a flexible locking arm 610 and a locking part 6101 disposed on the flexible locking arm 610. When the wire clamp 600 is closed, the flexible locking arm 610 moves along the locking edge 2107 until the locking part 6101 engages with the locking edge 2107, indicating that the wire clamp 600 is installed in place. Furthermore, the wire clamp 600 also has a protruding rib 620. The main body 210 has a corresponding groove (not shown) at the position of the protruding rib 620. When the wire clamp 600 is closed, the protruding rib 620 extends into the groove 2108, which on the one hand makes the positioning and installation of the wire clamp 600 and the wire insertion port 2104 more accurate, and on the other hand strengthens the connection between the wire clamp 600 and the main body 210.

[0061] The wire clamp 600 is provided with a wire-clamping part 630. The wire-clamping part 630 is disposed opposite to the second abutment part 2152. After the wire enters the mounting cavity 2103, it is clamped by both the wire-clamping part 630 and the second abutment part 2152. Furthermore, both the wire-clamping part 630 and the second abutment part 2152 are provided with anti-pull teeth 2106, which enhances the fixing effect and anti-pull performance of the wire 300.

[0062] When assembling the lamp 100, the automated equipment picks up the main body 210 and places it onto the fixed carrier. Then, it places the light source board 410 into the mounting cavity 2103, aligning the clearance portion with the wiring divider structure 220. The hot-pressing column 2111 on the bottom wall 2101 fixes the light source board 410 to the bottom wall 2101. The coiled wire, after being cut and stripped by a wire stripper, passes through the wire insertion port 2104 on the main body 210 and enters the interior of the main body 210. Upon encountering the wiring divider structure 220, it automatically separates and is guided to the corresponding soldering point 4102 on the light source board 410, where soldering is completed. The lamp cover 500 is then placed on top and ultrasonically welded to the main body 210. The main body 210 is then flipped over, and the wire clamp 600 and torsion spring 700 are installed, completing the lamp assembly.

[0063] Example 2:

[0064] Please see Figures 8-9 As shown, the lamp 100' includes a lampshade 500, a lamp body 230, a main conductor 300, and a light source board 410. In this embodiment, the lamp body 230 includes a base plate 2301 and a side plate 2302. The base plate 2301 and the side plate 2302 are separately arranged, which is equivalent to the bottom wall 2101 and the side wall 2102 being separately arranged in Embodiment 1.

[0065] When assembling the lamp 100', since the base plate 2301 and the side plate 2302 are set separately, there is no need for a wiring step. Simply stack and fix the base plate 2301, the light source plate 410, the main wire 300, the side plate 2302 and the lamp cover 500 from bottom to top in sequence, making the entire automated equipment process simpler and more efficient.

[0066] For details, please refer to Figures 10-11 As shown, the base plate 2301 has several clips 2311 and hot-melt pillars 2111. The light source plate 410 has openings corresponding to the positions of the hot-melt pillars 2111. The light source plate 410 is placed on the base plate 2301, and the hot-melt pillars 2111 are melted and fixed to the light source plate 410 by hot pressing. The base plate 2301 has a wire inlet groove 2312 corresponding to the wire position, and there is also a wire inlet groove 2312 on the side plate 2302. The wire inlet groove 2312 on the base plate 2301 and the wire inlet groove 2312 on the side plate 2302 are combined to form the wire insertion port 2104 in Embodiment 1, which is used to place the main wire 300. The main wire 300 is placed into the wire inlet groove 2312 and welded to the welding point 4102 on the light source plate 410. Next, install the side plate 2302. The base plate 2301 or side plate 2302 is designed with ultrasonic welding lines, which are connected by both clips 2311 and ultrasonic welding to ensure the connection strength between the base plate 2301 and side plate 2302. The base plate 2301 and side plate 2302 clamp and fix the main conductor 300. The cable inlet grooves 2312 of the base plate 2301 and side plate 2302 are respectively provided with anti-pull teeth 2106 to facilitate pressing the main conductor 300 and prevent it from being pulled out. Finally, the lampshade 500 is ultrasonically welded to the lamp body 230, completing the lamp assembly.

[0067] In summary, the lamp 100 of this utility model, by setting a wire-splitting structure 220, automatically separates the main conductor 300 to the corresponding welding point 4102 during wire threading, and then completes automatic welding. Due to the precise guidance of the wire-splitting structure 220, the conductor can maintain a stable position during welding, thereby improving the accuracy and reliability of welding. Finally, the excess wire opening 2104 is covered by the external wire clamp 600, which not only ensures the aesthetics of the product, but also prevents the conductor from loosening and falling off.

[0068] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
