Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0035] In the present application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a system, product or device including a series of units does not have to be limited to those clearly listed, but can include other units not clearly listed or inherent to these products or devices.

[0036] An embodiment of the present application provides a splicing structure of a lamp, which comprises at least two lamp bodies 100 and a coupler 200. After splicing of the plurality of lamp bodies, the lamp can be installed on a support such as a ceiling or a wall.

[0037] Referring to Figures 1-6 , two lamp bodies are taken as an example in the illustration, specifically a first lamp body 101 and a second lamp body 102. The lamp body 100 comprises a lamp shell 110 and a light-emitting assembly arranged in the lamp shell 110. The light-emitting assembly comprises a substrate and a light-emitting element arranged on the substrate. The lamp shell 110 has an opposite light-emitting side 103 and a back-light side 104. The position of the light-emitting assembly is the light-emitting side 103. The back-light side 104 is provided with a sink 111. The sink 111 is fixedly installed with a coupling seat 130. The coupling seat 130 is provided with a contact terminal 131 electrically connected with the light-emitting assembly. The lamp shell 110 has a matching part 120 abutting against an adjacent lamp body 100 in a splicing state.

[0038] The coupler 200 is used for connecting two adjacent lamp bodies 100. The coupler 200 comprises a base 210, two plug-in parts 220 and two clamping parts 230 protruding from the same side of the base 210. The two plug-in parts 220 are provided with a conductive part 240 therebetween.

[0039] In the splicing state, the matching parts 120 of the two adjacent lamp bodies 100 abut against each other. The base 210 spans the two matching parts 120. The two clamping parts 230 extend into the sink 111 of the corresponding lamp body 100 to clamp the two matching parts 120 from both sides. The two plug-in parts 220 are plug-in matched with the corresponding coupling seat 130, so that the contact terminal 131 and the conductive part 240 are electrically connected.

[0040] The coupling device 200 of the application has a plug-in part 220 and a clamping part 230. The plug-in part 220 is plugged into the coupling seat 130 in the corresponding lamp body 100 to achieve electrical connection. The clamping part 230 can be inserted into the sink groove 111 of the corresponding lamp body 100 to clamp the two matching parts 120 from both sides, so that the two lamp bodies 100 can be tightly attached. Therefore, the application can avoid the problem of difficult plugging of the plug-in part 220 due to the failure of the two lamp bodies 100 to be attached in place, improve the fault tolerance, and make it easier to install.

[0041] In the embodiment, the number of contact terminals 131 and the corresponding conductive parts 240 is three respectively, which are used to connect the zero line, the live line and the ground line 105. The setting of the ground line 105 avoids the risk of electric shock when the voltage is too high, making the lamp body safer as a whole.

[0042] Referring to Figures 5-6 The two clamping parts 230 are arranged between the two plug-in parts 220 and are spaced apart. The clamping part 230 is a plate structure as a whole, has a first surface 233 that acts on the matching part 120 and a second surface 234 that faces away from the matching part 120. In order to avoid the problem that the clamping part 230 is easily deformed and causes poor clamping effect when the thickness of the clamping part 230 is relatively thin, preferably, the thickness of the clamping part 230 is 2.0mm-3.1mm. Of course, considering the problem of easy insertion, the shape of the clamping part 230 is a round square.

[0043] It can be understood that when the lamp is spliced, the two lamp bodies 100 need to be attached in place before plugging. Therefore, the clamping part 230 of the application is higher than the plug-in part 220, so that the clamping part 230 can clamp the two matching parts 120 from both sides before plugging to make the two lamp bodies 100 tightly attached. This design is more convenient for subsequent plugging operation.

[0044] Preferably, the clamping part 230 has a guide slope 231 that guides the two matching parts 120 into the gap between the two clamping parts 230, that is, the guide slope 231 is arranged on the first surface 233 of the clamping part 230, and the guide slopes 231 of the two clamping parts 230 are oppositely arranged. Further, the clamping part 230 has a protruding rib 232 extending in the height direction with the guide slope 231. Of course, the number of protruding ribs 232 can be adaptively selected according to the needs. Considering the stability of the structure, preferably, the number of protruding ribs 232 is at least 2, for example, in the figure, there are 3 protruding ribs 232 distributed at intervals.

[0045] In the height direction, the thickness of the guide slope 231 is thick at the top and narrow at the bottom, so that in the process of plugging, the matching part 120 is in interference fit, making the two matching parts 120 more and more tightly attached. The plug-in part 220 can be easily aligned with the coupling seat 130 to achieve the plug-in fit of the two.

[0046] Of course, in order to avoid the coupling 200 from falling off the lamp, the base 210 and the matching part 120 are provided with anti-falling structure. Referring to Figures 5-9 , the top of the end cover 150 is provided with a notch 123 avoiding the base 210, in the splicing state, the coupling 200 is basically hidden in the sink 111, which can make the lamp more beautiful on the one hand, and can avoid the coupling 200 exposed to interfere with the installation of the lamp on the other hand. For example Figure 2 , the base 210 is in abutment with the bottom of the notch 123, and the upper surface of the coupling 200 is flush with the outer surface of the lamp shell 110.

[0047] The anti-falling structure specifically includes a positioning groove 124 provided on the side wall of the notch 123 and a positioning block 211 provided on the outer circumferential surface of the base 210. Of course, considering the stability of the structure, the number of positioning grooves 124 and positioning blocks 211 is multiple, for example, the number is 2 in the illustration, and they are symmetrically arranged. In order to facilitate installation and disassembly, the top and bottom positions of the positioning block 211 are arranged with guide inclined surfaces.

[0048] Referring to Figures 8-9 , in order to keep the coupling seat 130 in a given position, the inner side of the end cover 150 is provided with a mounting part 121 fixing the coupling seat 130, the mounting part 121 is arranged around the coupling seat 130, the shape is adapted to the outer contour of the coupling seat 130, the mounting part 121 has a positioning hole 122 passing through the upper and lower positions and adapting to the coupling seat 130, and the coupling seat 130 abuts against the bottom surface of the sink 111.

[0049] Referring to Figure 7 , the lamp shell 110 includes a base 140 with an open end and an end cover 150 cooperating with the base 140 to close the open end, the base 140 is a profile, and the end cover 150 is configured as the matching part 120. The profile includes two oppositely arranged side wall plates 142 and a partition plate 141 between the two side wall plates 142. In the height direction, the lower part of the partition plate 141 is the light emitting side 103, and the upper part is the backlight side 104. Part of the light emitting side 103 is provided with a lamp shade plate 143, and the light emitting assembly is installed on the lower surface of the partition plate 141. On the backlight side 104, the upper surface of the partition plate 141 and the side wall plate 142 form the sink 111 described above, and the coupling seat 130 is installed on the upper surface.

[0050] After splicing, the position of the splicing will have a dark area due to the presence of the end cover 150 (cannot transmit light), in order to solve this problem, the end cover 150 of the present application is provided with a detachably connected light-transmitting part 151, the light-transmitting part 151 is made of transparent material, and the light can be transmitted from the light-transmitting part 151 without being removed during splicing.

[0051] The splicing structure of the lamp provided by the embodiments of the present application can be coupled by the coupler 200 to realize mutual series connection, thereby realizing the series connection of multiple single lamps, including the order series connection of the first lamp body 100 and the second lamp body 100 as described above. Of course, the shape and length of the lamp of the present application can be adaptively set according to requirements, for example Figure 10 As shown, some lamp bodies have multiple end covers 150 (for example, the lamp body 100 is in the shape of a cross, and has four end covers 150), and the coupling seat 130 is installed in the mounting portion 121 of each end cover 150. By inserting and fitting the coupler 200 with the coupling seat 130, the lamp with various shapes and lengths can be spliced, and the flexibility is higher.

[0052] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure. When the technical features in different embodiments are embodied in the same figure, it can be considered that the figure also discloses the combination of each embodiment involved.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
