[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 7 As shown, the present invention discloses a lamp 100 comprising a lamp base assembly 10 and a lamp housing assembly 20 that are assembled and fixed to each other. The lamp base assembly 10 is typically provided with a light source module 11 for illuminating the entire lamp 100. The lamp housing assembly 20 is typically mounted on a wall to support or suspend the entire lamp base assembly 10, thereby securing the lamp 100. In this embodiment, the lamp 100 is a ceiling lamp, preferably a square ceiling lamp. Of course, in other embodiments, the lamp 100 may also have other shapes or types, and this is not a limitation here.

[0035] The lamp assembly 10 also includes an assembly 12 electrically connected to the light source module 11, and a locking member 13 mounted on the assembly 12. The assembly 12 extends a certain distance in the height direction and separates the lamp assembly 10 from the lamp housing assembly 20. Preferably, the assembly 12 is cylindrical and positioned at the center of the lamp assembly 10. The outer wall of the assembly 12 is provided with external threads 120. The locking member 13 is mounted on the outer side of the assembly 12 and has internal threads 130 corresponding to the external threads 120. The internal threads 130 and the external threads 120 cooperate to lock the assembly 12 to the lamp housing assembly 20. In this embodiment, the locking member 13 is a screw cap, but this is not intended to be limiting.

[0036] The lamp housing assembly 20 includes a fixing box 21 and a power module 22 and a fixing base assembly 23 housed in the fixing box 21. The power module 22 is electrically connected to the fixing base assembly 23. In the present invention, since the lamp 100 is preferably a square ceiling lamp, the shape of the fixing box 21 is preferably square, and the power module 22 is preferably fixed to one of the side edges of the fixing box 21. Since the assembly 12 is arranged at the center of the lamp head assembly 10, the fixing base assembly 23 is also roughly arranged at the center of the fixing box 21. This ensures that the lamp head assembly 10 and the lamp housing assembly 20 remain balanced when assembled. Of course, in other embodiments, the lamp 100 can also be circular, polygonal, or irregularly shaped. In this case, the positions of the fixing base assembly 23 and the power module 22 in the fixing box 21 can be arranged according to the specific lamp configuration, and are not limited to the above description.

[0037] During assembly, the assembly 12 is first assembled and fixed with the fixing seat component 23 through the fixing box 21 and electrically connected, and then the locking member 13 is used to cooperate with the thread of the assembly 12 to lock the assembly 12 and the fixing seat component 23. At this time, the power module 22, the fixing seat component 23, the assembly 12 and the light source module 11 can be electrically connected to each other, so that the lamp 100 is lit.

[0038] The following description will focus on the detailed description of the electrical connections between the power module 22 , the fixing base assembly 23 , the assembly 12 and the light source module 11 .

[0039] like Figures 7 to 9 Combined with Figure 4 As shown, a stopper 14 is provided at one end of the assembly 12 near the fixing base assembly 23. A through-hole 211 is formed on the fixing box 21 for the stopper 14 to pass through. The fixing base assembly 23 is provided with a receiving groove 231 recessed along the height direction for receiving the stopper 14. During assembly, the stopper 14 passes through the through-hole 211 and is at least partially received in the receiving groove 231 along its circumference. Preferably, the receiving groove 231 is recessed downward from the upper wall surface of the fixing base assembly 23. The stopper 14 is provided with a stopper groove 141 recessed inward from the edge. A corresponding stopper protrusion 232 is provided on the fixing base assembly 23, and the stopper protrusion 232 is located beside the receiving groove 231. Therefore, when assembling the lamp cap assembly 10, the mutual accommodation between the stopper 14 and the receiving groove 231, as well as the mutual restraint between the stopper protrusion 232 and the stopper groove 141, can ensure that the installation method and installation position between the lamp cap assembly 10 and the lamp housing assembly 20 are unique.

[0040] Of course, in other embodiments, the positions of the limiting groove 141 and the limiting protrusion 232 can also be interchanged, that is, the limiting groove 141 is set on the fixing seat assembly 23, and the limiting protrusion 232 is correspondingly set on the limiting portion 14; or, the fixed connection method between the limiting portion 14 and the fixing seat assembly 23 can also be other, as long as the assembly and fixation of the assembly 12 and the fixing seat assembly 23 can be achieved, and there is no limitation here.

[0041] In order to ensure that the limiting portion 14 can be smoothly inserted into the receiving groove 231, an insertion portion 230 connected to the receiving groove 231 is also provided on one side of the fixing seat assembly 23. The insertion portion 230 is preferably recessed inward from one side of the fixing seat assembly 23 and can accommodate the insertion groove of the assembly 12. The receiving groove 231 is located above the insertion portion 230, so that after the assembly 12 is inserted from the insertion portion 230, the limiting portion 14 can be exactly accommodated in the receiving groove 231.

[0042] The fixing base assembly 23 houses a first circuit board 24 and wiring terminals 25 and electrical connectors 26 integrated on the first circuit board 24. The power module 22 is electrically connected to the wiring terminals 25. Specifically, the fixing base assembly 23 includes a first cover 233 and a second cover 234 that are assembled and fixed to each other. The first circuit board 24 is fixed in the second cover 234. The electrical connectors 26 and the wiring terminals 25 are housed in a receiving space (not numbered) formed by the combination of the first cover 233 and the second cover 234. The receiving groove 231 is formed on the first cover 233 and is recessed downward from the upper wall surface of the first cover 233. In this embodiment, the first cover 233 and the second cover 234 are assembled and fixed in an upper and lower manner, and the second cover 234 is fixedly connected to the fixing box 21. After the first cover 233 is clamped and fixed to the second cover 234, it is locked and fixed to the fixing box 21 by bolts 27, thereby achieving a fixed connection between the fixing base assembly 23 and the fixing box 21. Of course, the connection method between the first cover 233 and the fixing box 21 can also be snap-on, adhesive, plug-in, etc., as long as the fixed connection between the fixing seat assembly 23 and the fixing box 21 can be achieved, no examples will be given here one by one, and no limitation will be made.

[0043] The first cover 233 also defines a clearance space 235 for the connection terminals 25. This clearance space 235 is spaced from and opposite the insertion portion 230. Within the clearance space 235, the connection terminals 25 are electrically connected to the power module 22 via the power cord 30. In other words, the power module 22 is positioned adjacent to the mounting assembly 23 and adjacent to the connection terminals 25. This allows the power cord 30 to electrically connect the power module 22 to the connection terminals 25, allowing power from the power module 22 to be transmitted to the connection terminals 25 and then to the first circuit board 24. In this configuration, the length of the power cord 30 is also relatively short, minimizing cost.

[0044] It can be understood that the fixing box 21 also houses the mains terminal 28 connected to the power module 22. The mains terminal 28 serves as a connection medium between the power module 22 and the external power supply. It is arranged at the edge of the fixing box 21 to facilitate the power cord 30 connected to the mains terminal 28 to pass through the fixing box 21 and connect to the mains.

[0045] A second circuit board 15 is provided at the bottom of the retaining portion 14. When the assembly 12 is assembled to the mounting assembly 23, the lower surface of the second circuit board 15 abuts against the electrical connector 26 to achieve electrical connection. A power cord 30 is mounted on the retaining portion 14. One end of the power cord 30 is welded to the second circuit board 15 and the other end is connected to the light source module 11. As a result, the power module 22 can provide power to the light source module 11 through the wiring terminals 25, the first circuit board 24, the electrical connector 26, the second circuit board 15, and the power cord 30, illuminating the light source module 11.

[0046] Because the second circuit board 15 is disposed at the bottom of the position-limiting portion 14, a corresponding notch 151 is formed on the edge of the second circuit board 15. This notch 151 corresponds to the position-limiting groove 141 on the position-limiting portion 14 and is used to secure and position the position-limiting portion 14 and the second circuit board 15 via the position-limiting protrusion 232 when assembling the lamp head assembly 10. Preferably, the second circuit board 15 is fastened to the position-limiting portion 14 via screws 16, but this is not intended to be limiting.

[0047] In this embodiment, the assembly 12 is hollow, allowing the power cord 30 to pass through the assembly 12 to electrically connect the second circuit board 15 to the light source module 11. The power cord 30 is not exposed, improving the aesthetics. To facilitate the management of the power cord 30, nuts 31 are provided at the top of the retaining portion 14 and the bottom of the assembly 12, respectively, to prevent the power cord 30 from becoming tangled.

[0048] like Figures 9 to 12 As shown, the electrical connector 26 includes an elastic member 261 fixed on the first circuit board 24 and an electrical contact 262 covered on the outside of the elastic member 261. The first cover 233 is also provided with a receiving hole 236 for accommodating the electrical contact 262. The receiving hole 236 is arranged throughout the entire first cover 233 to facilitate the top end of the electrical contact 262 to exceed the receiving hole 236. When the limiting portion 14 is accommodated in the receiving groove 231, the second circuit board 15 can be abutted against the electrical contact 262 and compress the elastic member 261, so that the light source module 11 and the power module 22 are electrically connected; and when the limiting portion 14 is separated from the receiving groove 231, the electrical contact 262 can be reset under the action of the restoring force of the elastic member 261, so that the light source module 11 and the power module 22 are disconnected.

[0049] Preferably, in this embodiment, the limiting portion 14 is a limiting plate, the electrical contact 262 is a copper contact, and the elastic member 261 is a spring. At least two, preferably three, copper contacts 262 and springs 261 are provided, thereby ensuring normal electrical conduction between the first circuit board 24 and the second circuit board 15. Of course, in other embodiments, the specific materials, configurations, and corresponding quantities of the electrical contacts 262 and the elastic member 261 can be varied according to actual circumstances, as long as the combined action of the electrical contacts 262 and the elastic member 261 ensures that the first circuit board 24 and the second circuit board 15 can maintain normal conduction or disconnection, and this is not a limitation herein.

[0050] Since the elastic member 261 in this embodiment is a spring, a corresponding copper contact 241 is provided on the first circuit board 24 , and the spring 261 is fixed at the copper contact 241 so that the power on the first circuit board 24 is transmitted to the spring 261 through the copper contact 241 and then to the copper contact 262 .

[0051] When assembling and fixing the lamp holder assembly 10 and the lamp housing assembly 20, first, pass the assembly part 12 through the through hole 211 on the fixing box 21 and move toward the side of the fixing seat assembly 23, so that the limiting portion 14 and the second circuit board 15 are limitedly accommodated in the receiving groove 231, and the limiting protrusion 232 is just embedded in the limiting groove 141; then, the locking part 13 and the assembly part 12 are tightened and fixed through the mutual cooperation of the external thread 120 and the internal thread 130. At this time, the connection and fixation of the lamp holder assembly 10 and the lamp housing assembly 20 are realized.

[0052] After assembly is completed, the power conduction path of the lamp 100 is as follows: after power is turned on, the power in the power module 22 reaches the terminal 25 through the power cord 30, and is transmitted from the terminal 25 to the first circuit board 24, the spring 261 and the copper contact 262, and then is transmitted to the second circuit board 15 by the copper contact 262. Finally, the power is transmitted to the light source module 11 through the power cord 30 inside the assembly 12, so that the light source module 11 is turned on and the lamp 100 is lit.

[0053] When the lamp holder assembly 10 needs to be disassembled from the lamp housing assembly 20 , the locking member 13 is directly rotated to loosen the locking member 13 , and then the assembly 12 is completely removed from the through hole 211 , thereby achieving disassembly of the lamp holder assembly 10 and the lamp housing assembly 20 .

[0054] like Figures 13 to 16 FIG. 1 is another preferred embodiment of the lamp of the present invention. In this embodiment, the lamp 100' also includes a lamp holder assembly 10' and a lamp housing assembly 20', and the structure of the lamp holder assembly 10' is the same as that of the lamp housing assembly 20'. Figure 1 The structure of the lamp holder assembly 10 is the same as that of the lamp housing assembly 20'. Figure 1 The structure of the lamp housing assembly 20 is basically the same, and the assembly method between the lamp head assembly 10' and the lamp housing assembly 20' is the same as Figure 1 The assembly method between the middle lamp holder assembly 10 and the lamp housing assembly 20 is also the same, that is, “first snap-fit ​​and then lock and secure”.

[0055] The main difference between lamp 100' and lamp 100 is that: only one lamp head assembly 10 is connected to the lamp housing assembly 20 of lamp 100, while five lamp head assemblies 10' are connected to the lamp housing assembly 20' of lamp 100'. The five lamp head assemblies 10' are evenly hung at the bottom of the lamp housing assembly 20' to achieve uniform lighting. At this time, five fixing seat assemblies 23' and five groups of power cords 30' are provided in the fixing box 21' to assemble and fix the five lamp head assemblies 10' respectively. The power supply module 22' can be provided with only one or more, as long as it can supply power to the five groups of power cords 30' at the same time.

[0056] In other words, the lamps 100, 100' of the present invention can be single-head ceiling lamps or multi-head ceiling lamps, and the number of lamp head assemblies of the multi-head ceiling lamp is not limited, and can be two, three, four or more, as long as they can be stably installed on the lamp housing assembly for lighting.

[0057] To sum up, after the lamps 100, 100' of the present invention are assembled by using the assembly parts 12, 12' to pass through the fixing boxes 21, 21' and the fixing seat components 23, 23', the locking parts 13, 13' and the assembly parts 12, 12' cooperate with each other to lock and fix the assembly parts 12, 12' and the fixing seat components 23, 23', so as to realize the electrical connection between the power modules 22, 22', the fixing seat components 23, 23', the assembly parts 12, 12' and the light source module 11, so that the lamps 100, 100' are lit; and when disassembling, the locking parts 13, 13' can be directly loosened to realize the separation of the locking parts 13, 13' from the assembly parts 12, 12', so that the light source module 11 is powered off, thereby realizing quick installation / disassembly, and after the installation is completed, the circuit conduction is safer and more stable, firm and reliable.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
