[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Figure 1 This paper illustrates an implementation scenario of the interconnected lighting system according to an embodiment of this application. Figure One ; Figure 2 An exploded view of the input device according to an embodiment of this application is shown. Figure One ; Figure 3 An exploded view of the input device according to an embodiment of this application is shown. Figure Two .

[0029] See Figure 1 , Figure 2 and Figure 3 The first aspect of this application provides an input device 100 for an interconnected lighting system, comprising: an input body 1, a power-collecting component 2, a first light source assembly 3, and a first connector 4. Wherein, The input body 1 has a first mounting cavity 11. The first mounting cavity 11 is a mounting cavity that extends from the first end to the second end of the input body 1. An opening is formed on one side of the first mounting cavity 11. A first light-transmitting element 5 is snapped into the opening of the first mounting cavity 11. The first light-transmitting element 5 is made of plastic and is a lampshade. The color of the lampshade can be selected according to the actual situation, such as a milky white lampshade or a transparent lampshade. An optical microstructure 51 can be formed on the surface of the lampshade to adjust the light emission effect of the first light source assembly 3. Specifically, the optical microstructure 51 can be an array of elongated structures with an arc-shaped cross-section. The elongated structures are integrally formed with the lampshade, and the extension direction of the elongated structures is perpendicular to the length direction of the input body 1.

[0030] In one specific implementation scenario, the input body 1 has a protrusion along its length at the opening of the first mounting cavity 11, and the lampshade has a groove that cooperates with the protrusion. The installation of the first light-transmitting element 5 is achieved through the snap-fit ​​cooperation between the protrusion and the groove.

[0031] The power-receiving component 2 includes a power-receiving end cover 21 and a power-receiving element 22. The power-receiving end cover 21 is connected to the first end of the input body 1 to close the first end of the first mounting cavity 11. The power-receiving element 22 is used to receive power and transmit electrical energy to the first light source assembly 3. The power-receiving element 22 has wires, and the power-receiving end cover 21 has a connection hole for wire insertion. The wires located outside the first mounting cavity 11 are used to connect to a device capable of supplying power to the input device 100, forming a power receiving end. The power receiving end can be provided with a corresponding power receiving interface. The wires located inside the first mounting cavity 11 are connected to the first light source assembly 3 to form a connection end 322, so as to transmit electrical energy to the first light source assembly 3, enabling the first light source assembly 3 to provide illumination.

[0032] The first light source assembly 3 is disposed within the first mounting cavity 11 along the length of the input body 1, and includes multiple first light sources 31 and a first circuit board 32. The first circuit board 32 is embedded in the first mounting cavity 11 and pressed onto the connecting end 322. Along the direction from the first end to the second end of the first mounting cavity 11, the multiple first light sources 31 are arranged at equal intervals on the first surface of the first circuit board 32. The first surface is the surface facing the first light-transmitting element 5, and is used to provide uniform illumination for the input device 100. A power-taking end 321 is provided on the second surface of the first circuit board 32, and the power-taking end 321 is electrically connected to the connecting end 322.

[0033] The first connector 4 can be a molded plastic part, with its first end connected to the second end of the input body 1, and its second end forming a first interconnection structure 42 for connecting the extension device 200 or the end device 300. Furthermore, the first connector 4 has a connecting channel 41 extending through it along its length. The connecting channel 41 communicates with the first mounting cavity 11, making the input device 100 an overall illuminated structure with an opening at one end. When connecting the extension device 200 and / or the end device 300, the mounting cavities corresponding to the extension device 200 and / or the end device 300 can be fully connected to the first mounting cavity 11, avoiding uneven lighting caused by obstruction structures between light source components, and making the light output of the interconnected lighting system more uniform and stable.

[0034] The first end of the first circuit board 32 abuts against the power supply end cover 21, the second end of the first circuit board 32 is located at the second end of the connection channel 41, and the second surface of the first circuit board 32 is provided with a connection end 322 for electrical connection of the extension device 200 or the end device 300, and the connection end 322 corresponds to the first interconnection structure 42.

[0035] With this design, the circuit board can fill the first mounting cavity 11 and the connection channel 41. The power taking component 22, the connection end 322 and other components will not obstruct the lighting effect of the first light source assembly 3. The first light source 31 can be completely oriented towards the first light-transmitting component 5 without being obstructed, so that the layout length of the first light source 31 can reach the longest possible layout length of the input device 100, thereby realizing the input device 100 without dark areas. That is, from the first end to the second end of the input device 100, it belongs to the light-emitting surface of the input device 100. The edge of the light-emitting surface starts from the location of the power taking end cover 21, and the light-emitting surface is uniform and continuous.

[0036] In one possible implementation, the input body 1 is a first profile. The first profile can be obtained by profile extrusion. Profile extrusion is low-cost and structurally stable, and can be cut to the target length as needed, facilitating low-cost control of the length of the input body 1. Specifically, along the length direction of the extruded first profile, its two ends correspond to the first end and the second end of the input body 1, respectively. The first profile is formed with a first sliding groove 12, which is located inside the first mounting cavity 11, and the length direction of the first sliding groove 12 is consistent with the length direction of the first profile. The first sliding groove 12 includes an upper groove body 121 and a corresponding lower groove body 122, which protrude relative to the inner sidewall of the first profile. The first circuit board 32 can be slidably connected to the first sliding groove 12 to realize the installation of the first light source assembly 3 relative to the input body 1.

[0037] Figure 4 A schematic diagram of the structure of the first profile of the input device according to an embodiment of this application is shown.

[0038] Combination Figure 4 In one possible implementation, the first profile is further formed with a first limiting member 13 and a second limiting member 14. The first limiting member 13 is located inside the first mounting cavity 11 and is a limiting strip extending along the length direction of the extrusion of the first profile. Further, the limiting strip can be connected to the upper groove 121 and / or the lower groove 122 of the first sliding groove 12, thereby improving the limiting effect. The limiting direction of the limiting strip is not consistent with the protrusion direction of the first sliding groove 12. Specifically, when the limiting strip is a rectangular strip, it can be vertically connected to the upper groove 121. Moreover, during automated manufacturing, the relative positions of the input body 1, the power-taking component 2, the first light source assembly 3, and the first connecting member 4 can remain consistent, improving the consistency of the input device 100.

[0039] The second limiting member 14 is located outside the first mounting cavity 11. The second limiting member 14 can also be a limiting strip extending along the length direction of the first profile extrusion. To improve the stability of the connection between the first connector 4 and the first profile, the limiting angles and / or limiting shapes of the first limiting member 13 and the second limiting member 14 are different. For example, if the limiting angle of the first limiting member 13 is towards the first light-transmitting member 5, then the limiting angle of the second limiting member 14 can be inclined relative to the first light-transmitting member 5. In terms of shape, the cross-sectional shape of the first limiting member 13 and the second limiting member 14 can be any one or a combination of triangle, rectangle, trapezoid, arc, polygon, etc., as long as the cross-sectional shapes of the first limiting member 13 and the second limiting member 14 are different.

[0040] A first connecting cavity 15 is also formed on the outside of the first mounting cavity 11. The first connecting cavity 15 is disposed away from the first mounting cavity 11, and its opening position is opposite to the first mounting cavity 11. To simplify the structure, the first connecting cavity 11 can be formed between two symmetrically arranged second limiting members 14. For convenient installation, mounting components can be provided in the first connecting cavity to install the device in the target position. The mounting components include, but are not limited to, magnets, adhesives, bolts, and clips.

[0041] Figure 5 A schematic diagram of the structure of the first connector of the input device according to an embodiment of this application is shown.

[0042] Combination Figure 5 The first end of the first connector 4 includes a second insert 43. The second insert 43 is used to embed into the second end of the first profile. The second insert 43 includes a first mating part 431 and a second mating part 432. The first mating part 431 is a mating groove that is adapted to the shape and angle of the first limiting part 13 to be fitted around the first limiting part 13. In a specific implementation scenario, the first limiting part 13 and the upper groove are connected in an L-shape, and the first mating part is an L-shaped groove fitted around the outer periphery of the first limiting part 13 and the upper groove. The groove surface of the first mating part 431 forms an inclined first guide surface 433 to facilitate installation. The second mating part 432 is a protrusion embedded inside the second limiting part 14, adapted to the shape and angle of the second limiting part 14. The second mating part 432 forms an inclined second guide surface 434 to facilitate installation.

[0043] In one specific implementation scenario, the first end of the first connector 4 is located at its end face. The slots of the first mating parts 431 and 432 are slightly larger than the dimensions of the first limiting member 13 and 14, or the slots of the first mating parts 431 and 432 can be the same size as the first limiting member 13 and 14. As the first mating parts 431 and 432 extend towards the second end of the first connector 4, the cross-sectional area within the slots of the first mating parts 431 and 432 gradually decreases. The grooves of the first mating parts 431 and 432 are smaller than the bottom of the grooves of the first mating parts 431 and 432. The grooves of the first mating parts 431 and 432 can be the same size as the first limiting part 13 and the second limiting part 14, or the grooves of the first mating parts 431 and 432 can be slightly smaller than the size of the first limiting part 13 and the second limiting part 14, so that the first connecting part 4 can be firmly snapped onto the first profile. When the groove at the first end is slightly larger than the size of the first limiting part 13 and the second limiting part 14, it also has the effect of facilitating installation.

[0044] During insertion, the first mating member 431 engages with the first limiting member 13, and the second mating member 432 engages with the second limiting member 14. A second positioning groove 44 is also formed on the connecting channel 41, which communicates with the first sliding groove 12, and the width of the second positioning groove 44 is smaller than that of the first sliding groove 12. Correspondingly, the second end of the first circuit board 32 has a protruding structure, allowing the protrusion to slide into the second positioning groove 44, while the shoulder of the second end abuts against the second insert 43 located at the end of the first sliding groove 12, thereby positioning the first circuit board 32. For ease of installation, both the first mating member 431 and the second mating member 432 can form guide slopes. To ensure the uniformity of illumination at the second end of the input device 100, the second positioning groove 44 extends towards the groove surface of the first light-transmitting member 5 to form a second light-guiding slope 45, so as to avoid the first connecting member 4 from blocking the light and to achieve uniform illumination without dark areas.

[0045] In one possible implementation, the second end of the first connector 4 is a first interconnection structure 42, which includes an interconnection groove 421 for matching the interconnection block 81 of the extension device 200 or the end device 300. The interconnection block 81 has a spring 82. The connecting end 322 faces the opening of the interconnection groove 421, thereby achieving electrical connection between the connecting end 322 and the spring 82 while the interconnection block 81 is engaged with the interconnection groove 421.

[0046] Figure 6 A schematic diagram of the power-taking end cover of the input device according to an embodiment of this application is shown.

[0047] Combination Figure 6In one possible implementation, the power-collecting end cover 21 includes an integrally formed connecting cover plate 211, a first insert 212, and a connecting base plate 213. The first insert 212 and the connecting base plate 213 are respectively vertically formed on the surface of the connecting cover plate 211 facing the input body 1. The connecting cover plate 211 covers the first end of the first profile to close the opening at the first end of the first profile. The first insert 212 is embedded in the first mounting cavity 11 of the first profile, and the connecting base plate 213 is inserted into the first connecting cavity 15, thereby achieving a snap-fit ​​fixation between the power-collecting end cover 21 and the first profile and enhancing the fixation effect.

[0048] The first insert 212 is provided with a first positioning element 2121 and a first positioning groove 2122. The first positioning element 2121 is a protruding strip that protrudes towards the first sliding groove 12. Its end is slightly smaller than the opening of the first sliding groove 12, and its tail gradually increases to facilitate installation and achieve insertion into the first sliding groove 12 for the first circuit board 32 to abut. The first positioning groove 2122 communicates with the first sliding groove 12. The groove width of the first positioning groove 2122 is smaller than the groove width of the first sliding groove 12. The first circuit board 32 has a protruding structure at its first end that matches the shape of the first positioning groove 2122, so that the end of the first circuit board 32 can be inserted into the first positioning groove 2122, and the non-protruding part of the first circuit board 32 abuts against the first positioning element 2121 to achieve positioning of the first circuit board 32.

[0049] Furthermore, the end face of the protrusion of the first circuit board 32 also abuts against the connecting cover plate 211, so that the illumination brightness of the light source assembly located on the first circuit board 32 can uniformly fill the entire first mounting cavity 11, realizing uniform illumination of the entire input device 100 without dark areas.

[0050] In one possible implementation, the first positioning groove 2122 extends towards the groove surface of the first light-transmitting element 5 to form a first light-guiding inclined surface 214, making the light output more uniform and preventing the first positioning groove 2122 from affecting the lighting effect. It should be added that, to improve lighting efficiency and adjust lighting uniformity, reflective paper can be placed at any position on the inner wall of the first profile, the first light-guiding inclined surface, and the second light-guiding inclined surface, thereby further ensuring its lighting uniformity.

[0051] Figure 7 A cross-sectional schematic diagram of the input device according to an embodiment of this application is shown.

[0052] Combination Figure 7In one possible implementation, the first end of the first profile also has a recessed half-hole 16 connecting the first mounting cavity 11 and the first connecting cavity 15. A wiring cavity 17 for the connecting end 322 to be embedded is formed between the connecting base plate 213, the recessed half-hole 16 and the first light source assembly 3. The thickness of the wiring cavity 17 is less than the thickness of the connecting end 322. By cutting the recessed half-hole 16 on the first profile, the wiring cavity 17 for the connecting end 322 to be embedded is formed. Since the thickness of the wiring cavity 17 is less than the thickness of the connecting end 322, the connecting base plate 213 and the first light source assembly 3 can compress the wire. Furthermore, the connecting base plate 213 can also have a wire-clamping hole 215, which allows part of the wire to be bent towards the wire-clamping hole 215. The wire is clamped by the wire-clamping hole 215, further improving the structural stability.

[0053] In one possible implementation, the first profile is made of metal, and the first light-transmitting element 5 is shorter than the first profile. When multiple devices are interconnected to form an interconnected lighting system, during use, due to the different materials of the first light-transmitting element 5 and the first profile, their materials will undergo different deformation coefficients under the same usage environment, especially during lighting. Based on this, the first light-transmitting element 5 of this application is shorter than the first profile to avoid structural damage and improve the stability of the interconnected lighting system. Correspondingly, by providing optical microstructures 51 on the first light-transmitting element 5, it is also possible to hide gaps.

[0054] Figure 8 A schematic diagram of the end device according to an embodiment of this application is shown.

[0055] See Figure 8 The second aspect of this application provides an end device 300 for an interconnected lighting system, comprising: an end body 6 having a second mounting cavity 61, the opening of the second mounting cavity 61 being connected to a second light-transmitting element 7; a first connector 4 including a connecting channel 41 passing through the first connector 4, the connecting channel 41 communicating with the second mounting cavity 61, a first end of the first connector 4 being connected to a second end of the end body 6, and a second end of the first connector 4 being connected to a closed end cap 62; a second connector 8, inserted into the other end of the second mounting cavity 61, including a second interconnection structure 811; and a second light source assembly 9 including a plurality of second light sources 91 and a second circuit board 92, the plurality of second light sources 91 being arranged at equal intervals on a first surface of the second circuit board 92 and facing the second light-transmitting element 7; a first end of the second circuit board 92 abutting against the inner wall of the closed end cap, and a second end of the second circuit board 92 abutting against the second connector 8.

[0056] The design of the end device 300 is similar to that of the input device 100. The difference is that the closed end cover does not require a power supply component, the shape of the embedded part of the closed end cover matches the first connector 4, and in order to facilitate the interconnection between devices, the second connector 8 of the end body 6 is provided with a second interconnection structure 811. The second interconnection structure 811 is used to adapt to the first interconnection structure 42. The second interconnection structure 811 includes an interconnection block 81, on which a spring 82 is provided. The interconnection block 81 is used to match the interconnection slot 421 of the expansion device 200 or the input device 100. One end of the spring 82 is electrically connected to the second circuit board 92, and the other end of the spring 82 is connected to the connection end 322 of the expansion device 200 or the input device 100.

[0057] In one possible implementation, the closed end cap is fitted with a wire for connecting to the power receiving terminal of the input device 100.

[0058] In another implementation scenario, when the interconnected scene has a corner, it is necessary to first use the end device 300 to close it, and then connect it to the next interconnected device via a wire. Furthermore, the closed end cap can be connected to a wire for connecting to the power receiving terminal of the next input device 100. In different interconnected lighting scenarios, there is a need for corner lighting. To improve the ease of installation of corner lighting structures, this application can achieve corner-free lighting by connecting the end device 300 and the input device 100 via a wire.

[0059] The third aspect of this application provides an extension device 200 for an interconnected lighting system, wherein a first end of the extension device 200 is connected to a second interconnection structure 811 adapted to the input device 100 of the first aspect of this application; and / or, a second end of the extension device 200 is connected to a first interconnection structure 42 adapted to the end device 300 of the second aspect of this application.

[0060] The design of the extension device 200 is similar to that of the input device 100 and the terminal device 300. The difference is that one end of the extension device 200 is a first interconnection structure 42 and the other end is a second interconnection structure 811, so as to achieve one-to-one interconnection.

[0063] In an interconnected scenario with input device 100, end device 300 and extension device 200, the number of input device 100, end device 300 and extension device 200 can be determined according to the actual needs of the scenario, and the devices can be interconnected along a specified lighting path to obtain an interconnected lighting system that meets the specified lighting path.

[0064] In one possible implementation, the spacing between adjacent light sources of any adjacent device is the same as the spacing between adjacent light sources on the same circuit board.

[0065] In the circuit board design process, by setting the spacing between adjacent light sources of any adjacent device to be consistent with the spacing between adjacent light sources on the same circuit board, it is possible to make the entire interconnected lighting system uniformly illuminated.

[0066] In one possible implementation, the main bodies of the input device 100, the terminal device 300, and the extension device 200 are made of the same profile.

[0067] With the design of the first connector 4, the input device 100, the end device 300 and the extension device 200 of this application embodiment do not need to be designed with additional profiles. Through the cooperation of the profiles and the first connector 4, input devices 100, end devices 300 and extension devices 200 with various target lengths and numbers can be obtained, which facilitates personalized customization, reduces costs and meets the personalized matching of various usage scenarios.
