In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0035] Referring to Figures 1 to 6 , the spliceable linear lamp 101 provided by the present invention includes a housing 102, a wiring harness 103, a wiring harness base 104, and a splicing and snapping member 105. The interior of the housing 102 has an installation cavity 106, and the installation cavity 106 is in a long strip shape. The housing 102 has a splicing port 204. The housing 102 has a variety of rib-like structures, and these rib-like structures or the grooves defined by the rib-like structures can be used to install other components of the spliceable linear lamp 101 or position other components. Figure 2 And Figure 6 The shown splicing port 204 is a notch on the rib-like structure. In some other embodiments, the splicing port 204 can also be set as a hole or a groove on the rib. Referring to Figure 1 And Figure 2 , the wiring harness 103 is connected to the housing 102. The wiring harness 103 includes a first connection terminal 201 and a second connection terminal 107. The first connection terminal 201 and the second connection terminal 107 are respectively located at both ends of the wiring harness 103. The first connection terminals 201 and the second connection terminals 107 of different spliceable linear lamps 101 can be inserted into each other. A part of the wiring harness 103 is accommodated in the installation cavity 106. The first connection terminal 201 is located inside the installation cavity 106, and the second connection terminal 107 extends out of the installation cavity 106. The second connection terminal 107 of one spliceable linear lamp 101 can extend into the installation cavity 106 of another spliceable linear lamp 101, so as to be connected to the first connection terminal 201 of another spliceable linear lamp 101. The wiring harness base 104 is connected to the housing 102, and at least a part of the wiring harness base 104 extends out of the installation cavity 106. The second connection terminal 107 is connected to the wiring harness base 104. The splicing and snapping member 105 is installed on the wiring harness base 104. The splicing and snapping member 105 protrudes relative to the wiring harness base 104 (taking Figure 1 And Figure 5 as an example, the wiring harness base 104 protrudes backward), and the splicing and snapping member 105 can be snapped into the splicing port 204.

[0036] The second connection terminal 107 and the flexible cable socket 104 extend out of the housing 102. Therefore, the second connection terminal 107 and the flexible cable socket 104 of a certain spliceable linear lamp 101 can easily extend into the installation cavity 106 of another spliceable linear lamp 101. When it is necessary to splice two spliceable linear lamps 101, the second connection terminal 107 and the flexible cable socket 104 of one of the spliceable linear lamps 101 can be inserted into the installation cavity 106 of the other spliceable linear lamp 101, so that the splicing clamping member 105 of one of the spliceable linear lamps 101 is clamped into the splicing interface 204 of the other spliceable linear lamp 101. After the splicing clamping member 105 is clamped into the splicing interface 204, the side wall of the splicing interface 204 can abut against the splicing clamping member 105 to prevent the splicing clamping member 105 from separating from the splicing interface 204, thereby preventing the two spliceable linear lamps 101 from separating from each other. That is, the splicing of the two spliceable linear lamps 101 can be realized by clamping the splicing clamping member 105 into the splicing interface 204. In addition, as the second connection terminal 107 and the flexible cable socket 104 of one of the spliceable linear lamps 101 extend into the installation cavity 106 of the other spliceable linear lamp 101, the second connection terminal 107 will be plugged into the first connection terminal 201, thereby realizing the connection of the power supply or communication cables of the two spliceable linear lamps 101, and there is no need to perform additional wiring, connection and other operations. Therefore, by extending the second connection terminal 107 and the flexible cable socket 104 of a certain spliceable linear lamp 101 into the interior of another spliceable linear lamp 101, the splicing of the structures of the two spliceable linear lamps 101 and the connection of the cables can be realized simultaneously. The splicing method of the spliceable linear lamp 101 provided by the present invention is simple, and the splicing of the spliceable linear lamp 101 is convenient.

[0037] Referring to Figure 1 、 Figure 2 and Figure 6 , in some embodiments, the housing 102 further includes an insertion guide groove 205. The insertion guide groove 205 extends along the length direction of the spliceable linear lamp 101. The flexible cable socket 104 is in a groove shape, and the side wall of the flexible cable socket 104 can slide into the insertion guide groove 205. When splicing two spliceable linear lamps 101, the flexible cable socket 104 of one spliceable linear lamp 101 can be first slid into the insertion guide groove 205 from one end of the insertion guide groove 205 of the other spliceable linear lamp 101, and then either spliceable linear lamp 101 is pushed to make the flexible cable socket 104 slide along the insertion guide groove 205 until the splicing clamping member 105 is clamped into the splicing interface 204. The wall surface of the insertion guide groove 205 has a limiting effect on the flexible cable socket 104. The setting of the insertion guide groove 205 can prevent the two spliceable linear lamps 101 from shifting during splicing, thereby avoiding the splicing clamping member 105 and the second connection terminal 107 from failing to move to the correct positions and improving the splicing efficiency.

[0038] In some embodiments, the splicing snap-in member 105 can be set as an elastic shrapnel. Relatively speaking, the shrapnel with a certain elasticity can reduce the resistance when two spliceable linear lights 101 are spliced or separated, facilitating the disassembly and assembly between the spliceable linear lights 101. During the splicing process, the splicing snap-in member 105 gradually approaches the splicing port 204. Before the splicing snap-in member 105 snaps into the splicing port 204, the splicing snap-in member 105 moves in a state of abutting against the rib where the splicing port 204 is located; due to the elasticity of the splicing snap-in member 105, the splicing snap-in member 105 will undergo a certain deformation, thereby reducing the interaction force between the splicing snap-in member 105 and the rib, thus reducing the friction of the movement of the splicing snap-in member 105 and the resistance during splicing. In addition, when the splicing snap-in member 105 is elastic, separating two spliced spliceable linear lights 101 is relatively simple. Just slightly force one spliceable linear light 101 to pull it away from the other spliceable linear light 101. When the acting force of the side wall of the splicing port 204 on the splicing snap-in member 105 increases to a certain extent, the splicing snap-in member 105 deforms and disengages from the splicing port 204. Since the second connection terminal 107 is fixed to the cable seat 104 by screws and the first connection terminal 201 is fixed to the housing 102, when the splicing snap-in member 105 disengages from the splicing port 204, the second connection terminal 107 will be separated from the first connection terminal 201.

[0039] Figure 1 and Figure 5 Fig. shows a relatively simple setting method of the splicing snap-in member 105. The splicing snap-in member 105 includes a first connecting portion 501, a second connecting portion 502, and a third connecting portion 503 that are connected in sequence. The first connecting portion 501 is connected to the cable seat 104. The connection between the second connecting portion 502 and the third connecting portion 503 protrudes relative to the cable seat 104, and the second connecting portion 502 can be bent relative to the first connecting portion 501. In some embodiments, the cable seat 104 is provided with an avoidance hole 504, and the splicing snap-in member 105 passes through the avoidance hole 504 and protrudes. The setting of the avoidance hole 504 provides sufficient space for the deformation of the splicing snap-in member 105.

[0040] Refer to Figure 2 and Figure 4, the housing 102 includes a radiator 202 and a side cover 203. The radiator 202 is detachably connected to the side cover 203. The side of the radiator 202 has an opening, and the side cover 203 covers the opening side of the radiator 202 to form an installation cavity 106. The detachable connection between the side cover 203 and the radiator 202 improves the maintenance convenience of the spliceable linear lamp 101. When maintenance of the spliceable linear lamp 101 is required, the side cover 203 can be directly removed to expose the components in the installation cavity 106 and then relevant maintenance operations can be carried out. In some embodiments, a snap connection method can be adopted between the radiator 202 and the side cover 203. Adopting the snap connection method can reduce the use of connecting parts such as screws. During the disassembly and assembly process, maintenance personnel do not need to use tools such as screwdrivers to disassemble and assemble the side cover 203, which is beneficial to improving the maintenance efficiency. Specifically, the radiator 202 includes a covering snap body 401, and the side cover 203 includes a covering snap groove 402. The covering snap body 401 can be snapped into the covering snap groove 402. Refer to Figure 2 and Figure 4 , when the side cover 203 needs to be removed, the maintenance personnel can first squeeze the side cover 203 in the up and down direction to slightly deform the side cover 203; after the side cover 203 is deformed, the upper covering snap body 401 is disengaged from the upper covering snap groove 402. Then the maintenance personnel use the lower covering snap body 401 as a fulcrum to turn over the side cover 203 until the lower covering snap body 401 is disengaged from the lower covering snap groove 402, and then the entire side cover 203 is removed.

[0041] Refer to Figure 3 , the spliceable linear lamp 101 further includes a light source assembly, a power supply 304, a power supply mounting bracket 305 and a lens 303. The light source assembly can emit light. The power supply mounting bracket 305 is connected to the radiator 202. The power supply mounting bracket 305 straddles the front side of the cable 103. The power supply 304 is connected to the front side of the power supply mounting bracket 305. The lens 303 for changing the light angle covers the light-emitting side of the light source assembly. In some embodiments, the light source assembly includes a first light source 301 and a second light source 302. Both the first light source 301 and the second light source 302 can be set as LED lamp boards. Both the first light source 301 and the second light source 302 are connected to the radiator 202. The light-emitting side of the first light source 301 faces upward, and the light-emitting side of the second light source 302 faces downward. The spliceable linear lamp 101 is usually suspended on the ceiling. Therefore, the second light source 302 that irradiates downward is mainly used for main lighting, while the first light source 301 that irradiates upward is mainly used for ambient lighting. Correspondingly, two lenses 303 can be provided. One lens 303 covers the upper side of the first light source 301, and the other lens 303 covers the lower side of the second light source 302. The brightness required for ambient lighting is low but the required irradiation range is wide. The upper and lower lenses 303 can be set to different shapes, and the light refraction angles of the two lenses 303 are different.

[0042] Next, the connection relationship between the flexible cable 103, the light source assembly, and the power supply 304 will be briefly described. Refer to Figure 7 , a section of the flexible cable 103 has a short exposed part (the copper wire 704 inside the flexible cable 103 is exposed). The spliceable linear lamp 101 further includes a female terminal 701, a male terminal 702, and a terminal mounting bracket 703. The terminal mounting bracket 703 is connected to the radiator 202, the female terminal 701 is connected to the terminal mounting bracket 703, and the copper wire 704 is threaded through the inside of the female terminal 701 in the left-right direction. The male terminal 702 is connected to the input end of the power supply 304 through a wire (the corresponding wire is not specifically shown). After the male terminal 702 and the female terminal 701 are inserted into each other, the contact 705 of the male terminal 702 can pass through the front side wall surface of the female terminal 701 from front to back and extend into the inside of the female terminal 701, and the contact 705 of the male terminal 702 contacts the copper wire 704. External high-voltage electricity is input through the first connection terminal 201 of the flexible cable 103 (after multiple spliceable linear lamps 101 are spliced, the high-voltage electricity will be transmitted to multiple spliceable linear lamps 101 through the flexible cable), and is transmitted to the power supply 304. The output end of the power supply 304 is connected to the light source assembly through a wire (the corresponding wire is not specifically shown). The power supply 304 converts the high-voltage electricity and outputs the converted voltage or current to the light source assembly.

[0043] Refer to Figure 8 , the spliceable linear lamp 101 further includes a wire fixing member 801. The wire fixing member 801 has a wire fixing groove 802. The cable part of the flexible cable 103 can be snapped into the wire fixing groove 802 to be fixed, and the wire fixing member 801 is connected to the radiator 202. The wire fixing member 801 includes a first wire fixing connection body 803, and the radiator 202 includes a second wire fixing connection body 403 (combining Figure 2 and Figure 4 , the splicing interface 204 is opened on the second wire fixing connection body 403). Both the first wire fixing connection body 803 and the second wire fixing connection body 403 are hook-shaped, and the first wire fixing connection body 803 and the second wire fixing connection body 403 can be hooked together. Generally speaking, the flexible cable 103 is relatively long, and the wire fixing member 801 can fix the middle part of the flexible cable 103 on the radiator 202, thereby preventing the middle part of the flexible cable 103 from being coiled or wound. The spliceable linear lamp 101 further includes a suspension rope 306 and a hook 307. The upper end of the suspension rope 306 is connected to the ceiling, the lower end of the suspension rope 306 is connected to the hook 307, and the radiator 202 further includes a hanging groove 404. The hook 307 can be hooked into the hanging groove 404, and the hook 307 can slide along the hanging groove 404. The suspension rope 306 and the hook 307 are used to hang the spliceable linear lamp 101. By adjusting the relative position of the hook 307 and the housing 102, the hanging posture or position of the spliceable linear lamp 101 can be flexibly adjusted.

[0044] Refer to Figure 9 andFigure 10 , the present invention also provides a lamp group, which includes the spliceable linear lamp 101 described in the above embodiments, and the lamp group is convenient to splice and assemble.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
