Description

Technical Field

[0001] The present invention relates to the technical field of LED strip lights, and particularly to a strip light end cap assembly and an LED strip light structure using the end cap. Background Art

[0002] An LED strip light is a multi - section continuous long strip structure, usually flexible, and is commonly used for indoor and outdoor lighting. Users can cut it at a predetermined cutting point according to the length they need, and insert a power - supply end cap assembly corresponding to the cut position to supply power to the LED strip light, thereby lighting up the LED strip light. One end of the power - supply end cap assembly is connected to alternating current through a plug, and the other end is connected to the strip light.

[0003] In use, the flexible strip light is often bent into a suitable shape by the user according to the specific use environment. However, after a period of use, the LED strip light often has intermittent problems, which are often caused by poor electrical connection at the connection between the end cap assembly and the strip light. The currently common electrical connection method is to set a contact surface on one side surface of the strip light to achieve conductive connection, and this method belongs to hard contact, which has high requirements for the production and manufacturing process. If there is a slight deviation during manufacturing and assembly, it is easy to form an open circuit. In addition, due to the different use environments and installation position structures of users, if the connection between the end cap and the strip light is bent, it is also very easy to form poor contact and an open circuit. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a strip light end cap assembly, in which the end cap assembly clamps the strip light through a spring piece, so that the strip light and the end cap assembly maintain an effective conductive connection and are not easily open - circuited.

[0005] Another technical problem to be solved by the present invention is to provide an LED strip light structure in which the strip light and the end cap assembly maintain an effective conductive connection and are not easily open - circuited.

[0006] Another technical problem to be solved by the present invention is to provide an LED strip light structure that can be bent into a ring structure without open - circuiting.

[0007] Another technical problem to be solved by the present invention is to provide an LED strip light structure in which the installation of the strip light and the end cap is convenient.

[0008] To solve the above - mentioned technical problems, the present invention provides an end cap assembly for an LED strip light structure. The LED strip light structure includes a strip light and an end cap assembly. The strip light includes a housing and a conductive member. The end cap assembly includes:

[0009] An end cap that can be hermetically connected to the housing;

[0010] A shrapnel is disposed inside the end cap and can be electrically connected to the conductive member.

[0011] A wire passes through the end cap and is electrically connected to the shrapnel.

[0012] There are two shrapnels, which include a first clamping portion and a second clamping portion, and both the first clamping portion and the second clamping portion are electrically connected to the conductive member.

[0013] As an improvement of the above solution, the shrapnel includes a connecting portion. The first clamping portion includes a first connecting section, a first elastic section, and a first clamping section connected in sequence. The second clamping portion includes a second connecting section, a second elastic section, and a second clamping section connected in sequence. The connecting portion is connected to the first connecting section and the second connecting section.

[0014] As an improvement of the above solution, the distance between the first elastic section and the second elastic section is less than the distance between the first clamping section and the second clamping section.

[0015] As an improvement of the above solution, the end cap includes an outer housing and an inner housing. The front end of the outer housing is provided with a first opening end for inserting the light strip. The inner housing is disposed at the rear end corresponding to the first opening. Wherein, the front end of the inner housing is provided with a second opening end for inserting the first connecting section and the second connecting section. The rear end of the inner housing corresponding to the second opening end is a wire fixing end, and one end of the wire is fixed to the wire fixing end.

[0016] As an improvement of the above solution, the end cap assembly is further provided with a spring, and the spring is disposed between the shrapnel and the end cap.

[0017] As an improvement of the above solution, bumps or recessed pits are provided on the first clamping section and / or the second clamping section.

[0018] Correspondingly, the present invention also provides a light strip end cap assembly, which includes an end cap, a shrapnel, and a wire. The end cap is used to support the shrapnel. The shrapnel includes a first clamping portion and a second clamping portion and is disposed inside the end cap. The wire passes through the end cap and is electrically connected to the shrapnel.

[0019] Correspondingly, the present invention also provides an LED light strip structure, which includes a light strip and an end cap assembly. The light strip includes a housing, a substrate provided with an LED light source, and a conductive member. The end cap assembly is the above-mentioned end cap assembly.

[0020] As an improvement of the above solution, the conductive member includes a bottom conductive member disposed parallel to the substrate along the length direction of the light strip and a double-sided conductive member disposed at the shearing point. The double-sided conductive member is electrically connected to the bottom conductive member, and the first clamping portion and the second clamping portion are respectively electrically connected to the bottom conductive member and the double-sided conductive member, or both the first clamping portion and the second clamping portion are electrically connected to the double-sided conductive member.

[0021] As an improvement of the above solution, the substrate is a flexible aluminum substrate, the bottom conductive member is a copper sheet, and an insulating layer is provided between the substrate and the bottom conductive member.

[0022] Implementing the present invention has the following beneficial effects:

[0023] The LED light strip structure provided by the present invention clamps the double-sided conductive member through the elastic piece, and then fastens the elastic piece in the end cover, which not only effectively prevents the double-sided conductive member from loosening, but also ensures the firm connection between the substrate and the wire, preventing poor contact between the light strip and the wire.

[0024] The distance between the first elastic section and the second elastic section of the present invention is greater than the distance between the first clamping section and the second clamping section. In this way, when installing and disassembling the end cover, the elastic piece can be quickly and conveniently clamped on the double-sided conductive member and the conductive member, and disassembled from the substrate; in addition, the distance between the first connecting section and the second connecting section of the present invention is less than the distance between the first elastic section and the second elastic section, effectively ensuring the elasticity of the elastic piece and ensuring that the first clamping section and the second clamping section can be clamped on the double-sided conductive member and the conductive member.

[0025] The end cover of the present invention realizes the firm connection with the outer shell and the elastic piece through the cooperation of the outer shell body and the inner shell body. Among them, the front end of the inner shell body is provided with a second opening end into which the first connecting section and the second connecting section are inserted. In addition, the wire fixing end corresponding to the second opening end fixes the end of the wire in the inner shell body, thereby realizing an effective electrical connection between the elastic piece and the wire.

[0026] The double-sided conductive member in another embodiment of the present invention includes a bottom plate and an extension portion. The bottom plate is disposed on the substrate, and the extension portion is folded upward along the bottom plate and extends outward toward the end of the substrate. The bottom plate ensures that the substrate can obtain electrical energy from the underlying conductive member. The extension portion is provided with a bending structure, and the bending structure has a preset width to increase the contact area between the extension portion and the end cover assembly. The elastic piece is clamped on the bending structure of the double-sided conductive member, that is, the elastic piece is clamped in the left-right direction of the substrate. The LED light strip structure of this embodiment is more suitable for being bent into a ring structure, and the connection and conduction effect of the LED light strip structure of this embodiment is better, and the contact adaptability is better.

[0027] In another embodiment of the present invention, a spring is further provided between the shrapnel and the wire, so that the shrapnel can move a short distance within the inner housing of the end cap, enabling better electrical connection between the shrapnel and the wire.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] Refer to Figure 1 , a kind of LED strip structure provided by the present invention includes a strip and an end cap assembly. The strip includes a housing 11, a substrate 12, and an LED light source 13. The end cap assembly includes an end cap 21, a shrapnel 22, and a wire 23.

[0040] Figure 2is a sectional view of the outer shell cut along a direction perpendicular to its length. Refer to Figure 2 , the outer shell 11 is a tubular structure, provided with a card slot 112 for placing the substrate 12 and a hollow cavity 111 for accommodating the light source 13. Preferably, the outer shell 11 is made of a flexible light-transmitting insulating material, and the substrate 12 is an aluminum flexible substrate. The outer shell 11 is provided with a card slot 112 for clamping the substrate 12. When the light strip is assembled, the substrate 12 is clamped into the card slot 112. Among them, the card slot 112 communicates with the hollow cavity 111, so that the light source 13 arranged on the substrate 12 can extend into the hollow cavity 111. The card slot 112 of the present invention is not only used for installing the substrate 12, but also can limit the position of the substrate 12, and further limit the distance between the light source 13 and the light-emitting surface of the outer shell 11 (that is, Figure 2 the upper surface of the outer shell 11 in

[0041] Figure 3 is a sectional view of the light strip cut along a direction perpendicular to its length. For the convenience of display and description, the cutting plane is selected at the predetermined cutting point position of the light strip, and Figure 3 the outer shell 11 is hidden in Figure 3 . When the user uses the light strip, the light strip will be cut at the predetermined cutting point. The front surface of the substrate 12 is provided with a plurality of the LED light sources 13 and cutting points along its length direction. Refer to

[0042] , at least two bottom conductive members 121 are arranged on the back surface of the substrate 12 along its length direction. Among them, a double-sided conductive member 122 is correspondingly arranged at each cutting point, and each double-sided conductive member 122 is electrically connected to each bottom conductive member 121 respectively. The double-sided conductive member 122 and the bottom conductive member 121 are both conductive members. The bottom conductive member 121 can be a columnar long wire, a plate or other shapes, and the material is a conductive member or other conductive materials. Preferably, the bottom conductive member 121 is a copper strip-shaped thin plate, having the same length as the substrate 12 and a width less than half of the width of the substrate 12. After the assembly of the light strip is completed, the bottom conductive member 121 is arranged parallel to the substrate 12, and there is an insulating structure (such as an insulating layer or insulating paint) between the bottom conductive member 121 and the substrate 12. The bottom conductive member 121 can be fixed on the back surface of the substrate 12 by means of evaporation plating, welding, etc., and the bottom conductive member 121 and the substrate 12 form a double-layer structure.

[0042] Among them, the substrate 12 of the present invention is a flexible substrate 12, which can be bent, folded and wound to a certain extent; the LED light sources 13 are uniformly arranged on the substrate 12, and the light emitted by the LED light sources 13 is emitted from the light-emitting surface of the outer shell 11.

[0043] In order to achieve electrical connection between the bottom conductive member 121 and the substrate 12 in the upper and lower layers, the present invention provides a double-sided conductive member 122 on the front surface of the substrate 12, which can form an electrical connection with the bottom conductive member 121 by means of soldering, PIN pins or terminals. Preferably, the double-sided conductive member 122 of the present invention is a pad, which enables the upper circuit board to obtain electrical energy from the bottom conductive member 121 in the lower layer by spot soldering.

[0044] To ensure that the light strip can still form an electrical connection with the end cap after being cut short, the double-sided conductive member 122 is provided at the cutting points of the substrate 12, that is, a double-sided conductive member 122 is provided at each cutting point.

[0045] In the existing technology, the end cap is directly covered on the end of the light strip. A wire is provided inside the end cap. When the end cap is covered on the end of the light strip, one end of the wire or the protruding part connected to the wire directly makes hard contact with the single-sided conductive member. The other end is connected to alternating current through a plug to supply power to the light strip. If the connection between the end cap and the light strip is bent, the single-sided conductive member on the substrate 12 is likely to have poor contact with the wire inside the end cap, easily causing an open circuit. In the present application, in addition to changing the original single-sided conductive member in the light strip to a double-sided conductive member 122, the internal structure of the end cap is redesigned to better perform connection and conduction.

[0046] Specifically, the present invention connects the light strip and external alternating current through an end cap assembly. Refer to Figure 4 , the end cap 21 is covered on the end of the housing 11 and forms a sealed connection with the housing 11. The elastic piece 22 is used to clamp on the double-sided conductive member 122 and the bottom conductive member 121 and is fixed inside the end cap 21. The elastic piece 22 can form an electrical connection with the double-sided conductive member 122 and the bottom conductive member 121. The wire passes through the end cap 21 and forms an electrical connection with the elastic piece 22.

[0047] The present invention clamps the double-sided conductive member 122 by the elastic piece 22 and then fixes the elastic piece 22 inside the end cap 21, which not only effectively prevents the double-sided conductive member 122 from loosening, but also ensures the firm connection between the substrate 12 and the wire 23, preventing poor contact between the double-sided conductive member 122 and the wire 23.

[0048] To ensure that the elastic piece 22 can effectively clamp the double-sided conductive member 122, refer to Figure 5, the shrapnel 22 of the present invention includes a first clamping portion 221 and a second clamping portion 222 symmetrically arranged, and a connecting portion 223 connecting the first clamping portion 221 and the second clamping portion 222. The first clamping portion 221 includes a first connecting segment 2211, a first elastic segment 2212, and a first clamping segment 2213 connected in sequence. The second clamping portion 222 includes a second connecting segment 2221, a second elastic segment 2222, and a second clamping segment 2223 connected in sequence. The connecting portion 223 is connected to the first connecting segment 2211 and the second connecting segment 2221, and the first clamping segment 2213 and the second clamping segment 2223 are respectively clamped on the double-sided conductive member 122 and the bottom conductive member 121.

[0049] The shrapnel 22 of the present invention not only needs to clamp the double-sided conductive member 122 and the bottom conductive member 121 tightly, but also needs to be convenient for installation and disassembly, and can be fastened inside the end cap 21. Therefore, the distance between the first connecting segment 2211 and the second connecting segment 2221, the distance between the first elastic segment 2212 and the second elastic segment 2222, and the distance between the first clamping segment 2213 and the second clamping segment 2223 of the shrapnel 22 of the present invention need to be specifically limited to achieve the above functions simultaneously.

[0050] Among them, the distance between the first connecting segment 2211 and the second connecting segment 2221 is a, the distance between the first elastic segment 2212 and the second elastic segment 2222 is b, and the shortest distance between the first clamping segment 2213 and the second clamping segment 2223 is c. Then, it is necessary to satisfy c < b. Preferably, a < c < b.

[0051] Specifically, the distance c between the first clamping segment 2213 and the second clamping segment 2223 needs to be designed according to the total thickness of the substrate 12, the double-sided conductive member 122, and the bottom conductive member 121. However, the distance b between the first elastic segment 2212 and the second elastic segment 2222 must be greater than the distance c between the first clamping segment 2213 and the second clamping segment 2223. Only in this way can the shrapnel 22 be quickly and conveniently clamped on the double-sided conductive member 122 and the bottom conductive member 121 and disassembled from the substrate 12 when installing and disassembling the end cap 21. In addition, the distance a between the first connecting segment 2211 and the second connecting segment 2221 is less than the distance b between the first elastic segment 2212 and the second elastic segment 2222, which can better ensure the elasticity of the shrapnel 22 and ensure that the first clamping segment 2213 and the second clamping segment 2223 can be tightly clamped on the double-sided conductive member 122 and the bottom conductive member 121.

[0052] Preferably, in order to further ensure the connection between the elastic piece 22 and the double-sided conductive piece 122 and the bottom conductive piece 121, a concave pit may also be provided at the positions where the first clamping section 2213 and the second clamping section 2223 of the elastic piece 22 contact the double-sided conductive piece 122 and the bottom conductive piece 121, and a raised point is provided at the positions where the double-sided conductive piece 122 and the bottom conductive piece 121 contact the elastic piece 22. The raised point and the concave pit are in conformity, so as to better clamp the lamp strip and the end cover.

[0053] Furthermore, in order to ensure that the end cover 21 can be tightly closed on the outer shell 11 and ensure that the elastic piece 22 can be fastened in the end cover 21, see Figure 6 , the end cover 21 includes an outer shell body 211 and an inner shell body 212. A first opening 2111 for inserting the lamp strip is provided at the front end of the outer shell body 211; the inner shell body 212 is arranged at the rear end 2112 corresponding to the first opening end 2111. Among them, a second opening end 2121 for inserting the first connecting section 2211 and the second connecting section 2221 is provided at the front end of the inner shell body 212, and the rear end of the inner shell body 212 corresponding to the second opening end 2121 is a wire fixing end 2122, and one end of the wire 23 is fixed on the wire fixing end 2122.

[0054] In order to realize an effective conductive connection between the wire 23 and the elastic piece 22, see Figure 5 , a conductive piece 231 is provided at one end of the wire 23, and the conductive piece 231 is arranged on the wire fixing end 2122. When the first connecting section 2211 and the second connecting section 2221 are inserted into the inner shell body 212, the connecting parts connected to the first connecting section 2211 and the second connecting section 2221 abut against the conductive piece 231 to realize conductive connection. Among them, the conductive piece 231 is preferably a conductive metal piece.

[0055] The outer shell body 211 and the inner shell body 212 are of an integral structure and can be integrally formed by injection molding. The end of the wire 23 can be fixed in the end cover 21 by means of in-mold injection, caulking, snap melting or screw fastening.

[0056] Embodiment 2

[0057] Embodiment 1 has a very good effect on the bending method in one case, that is, if the lamp strip is bent into a ring shape, and Figure 2In the above-mentioned upper housing and lower housing are respectively used as the outer edge and inner edge of the ring structure, and the left housing and right housing are used as the bending methods on the sides. However, if the bending direction is rotated by 90°, that is, when the left housing and right housing are respectively used as the outer edge and inner edge of the ring structure, and the upper housing and lower housing are used as the sides for bending, the design purpose may not be achieved. Therefore, in this embodiment, the double-sided conductive member 122 and the elastic piece 22 are both rotated by 90° on the basis of Embodiment 1, so as to match different bending environments of the light strip. For the parts not introduced in this embodiment, they are the same as those in Embodiment 1.

[0058] See Figure 7 and Figure 8 , another LED light strip structure provided by the present invention includes a light strip and an end cap assembly. The light strip includes a housing 11, a substrate 12, and an LED light source 13. The end cap assembly includes an end cap 21, an elastic piece 22, and a wire 23.

[0059] Different from Embodiment 1, the double-sided conductive member 122 in this embodiment includes a bottom plate 1221 and an extension portion 1222. The bottom plate 1221 is disposed on the substrate 12. The extension portion 1222 is turned up along the bottom plate 1221 and extends outward toward the end of the substrate 12. The bottom plate 1221 is used to ensure that the substrate 12 can obtain electrical energy from the bottom conductive member 121 at the lower layer. Among them, the bottom plate 1221 forms a conductive connection with the bottom conductive member 121 by means of PIN pins or terminals, etc.; the extension portion 1222 is used to achieve a conductive connection with the end cap assembly. In order to ensure that the extension portion 1222 can achieve a tight conductive connection with the end cap assembly, the extension portion 1222 is provided with a bending structure, and the bending structure has a preset width to increase the contact area between the extension portion 1222 and the end cap assembly.

[0060] Specifically, the elastic piece 22 is clamped on the bending structure of the double-sided conductive member 122 and fastened in the end cap 21. The wire 23 passes through the end cap 21 and forms a conductive connection with the elastic piece 22. In the present invention, the elastic piece 22 is used to clamp the double-sided conductive member 122, and then the elastic piece 22 is fastened in the end cap 21, which not only effectively prevents the double-sided conductive member 122 from loosening, but also ensures the tight connection between the substrate 12 and the wire 23, and prevents poor contact between the double-sided conductive member 122 and the wire 23.

[0061] To ensure that the elastic piece 22 can effectively clamp the double-sided conductive piece 122, the elastic piece 22 of the present invention also includes a first clamping portion 221 and a second clamping portion 222 symmetrically arranged, and a connecting portion 223 connecting the first clamping portion 221 and the second clamping portion 222. The first clamping portion 221 includes a first connecting segment 2211, a first elastic segment 2212, and a first clamping segment 2213 connected in sequence. The second clamping portion 222 includes a second connecting segment 2221, a second elastic segment 2222, and a second clamping segment 2223 connected in sequence. The first clamping segment 2213 and the second clamping segment 2223 are respectively clamped on the bending structure of the double-sided conductive piece 122.

[0062] Among them, the elastic piece 22 in Embodiment 1 is clamped in the up-down direction of the substrate 12, and the elastic piece 22 in this embodiment is clamped in the left-right direction of the substrate 12. Due to the different clamping position directions, for the corresponding bending situation of the light strip, the connection and conduction effect of the LED light strip structure in this embodiment is better, and the contact adaptability is better.

[0063] Similarly, the elastic piece 22 of the present invention not only needs to clamp the double-sided conductive piece 122 tightly, but also needs to be convenient for installation and disassembly, and can be fastened inside the end cover 21. Therefore, the distance between the first connecting segment 2211 and the second connecting segment 2221, the distance between the first elastic segment 2212 and the second elastic segment 2222, and the distance between the first clamping segment 2213 and the second clamping segment 2223 of the elastic piece 22 of the present invention need to be specifically limited to simultaneously achieve the above functions.

[0064] Among them, the distance between the first connecting segment 2211 and the second connecting segment 2221 is a, the distance between the first elastic segment 2212 and the second elastic segment 2222 is b, and the distance between the first clamping segment 2213 and the second clamping segment 2223 is c, and c < b. Preferably, a < c < b.

[0065] Specifically, the distance c between the first clamping segment 2213 and the second clamping segment 2223 needs to be designed according to the width of the bending structure, but the distance b between the first elastic segment 2212 and the second elastic segment 2222 must be greater than the distance c between the first clamping segment 2213 and the second clamping segment 2223, so that when installing and disassembling the end cover 21, the elastic piece 22 can be quickly and conveniently clamped on the double-sided conductive piece 122 and disassembled from the double-sided conductive piece 122. Preferably, the distance a between the first connecting segment 2211 and the second connecting segment 2221 is less than the distance b between the first elastic segment 2212 and the second elastic segment 2222, which can better ensure the elasticity of the elastic piece 22 and ensure that the first clamping segment 2213 and the second clamping segment 2223 can clamp the bending structure of the double-sided conductive piece 122.

[0066] Preferably, in order to further ensure the connection between the elastic piece 22 and the double-sided conductive piece 122 and the bottom conductive piece 121, recessed pits may also be provided at the positions where the first clamping section 2213 and the second clamping section 2223 of the elastic piece 22 are in contact with the double-sided conductive piece 122 and the bottom conductive piece 121, and raised points are provided at the positions where the double-sided conductive piece 122 and the bottom conductive piece 121 are in contact with the elastic piece 22. The raised points and the recessed pits match, so as to better clamp the lamp strip and the end cover.

[0067] Embodiment III

[0068] In order to optimize the structure of the end cover in Embodiment I and Embodiment II and achieve the purpose of better contact between the end cover and the lamp strip, further optimization is carried out in this embodiment. For the sake of simple demonstration, only the improvement of the solution in Embodiment I is shown, and the same improvement can also be applied to the solution in Embodiment II.

[0069] See Figure 9 , an LED lamp strip structure provided by the present invention includes a lamp strip and an end cover assembly. The lamp strip includes a housing 11, a substrate 12, and an LED light source 13. The end cover assembly includes an end cover 21, an elastic piece 22, and a wire 23.

[0070] Different from Embodiment 1, the end cover assembly of this embodiment further includes a spring 24, so that the elastic piece 22 can move a short distance within the inner housing 212 of the end cover 21, or the elastic piece 22 has a certain swing clearance. During this movement or swing process, the elastic piece 22 is always electrically connected to the wire 23. Such a design can enable the elastic piece 22 to have a better conductive connection with the lamp strip.

[0071] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
