Description

A type of light strip with secure cable connection Technical Field

[0001] This invention relates to the field of LED strip technology, and more particularly to an LED strip with a secure cable connection. Background Technology

[0002] Existing LED strip external connections are generally made by directly soldering electrical wires to the LED board. This method of soldering is inconvenient. The solder pads are prone to falling off and delamination due to repeated high-temperature soldering. Furthermore, the connection is not firm after soldering. Excessive pulling force can easily cause the solder joints to break or even tear the LED board. Technical issues

[0003] In view of the above situation, it is necessary to propose a light strip with a more robust cable connection that improves tensile strength and overcurrent protection.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a light strip with a secure cable connection, comprising:

[0005] Light panel;

[0006] LED beads, a plurality of the LED beads are spaced apart on the lamp board;

[0007] An adapter board includes a substrate layer and at least two circuit layers disposed within the substrate layer. The adapter board is provided with a plurality of first connecting portions and a plurality of second connecting portions. The first connecting portions and the second connecting portions are electrically connected through the circuit layers. The lamp board is welded to the first connecting portions and the lamp board has an overlapping portion with the substrate layer.

[0008] The external wiring is welded to the second connection part.

[0009] Furthermore, the external wiring is connected to the adapter plate laterally or vertically.

[0010] Furthermore, the substrate layer is provided with a circuit through hole, and the circuit through hole is filled with a conductor for electrically connecting the circuit layers at different heights.

[0011] Furthermore, the first connecting part is one of the following: a U-shaped hole opening to the end, a vertically penetrating through hole, an exposed solder joint groove, a welding protrusion, or a plane exposing the solder joint.

[0012] Furthermore, the second connecting part is a U-shaped hole opening to the end or a vertically penetrating through hole.

[0013] Furthermore, an insulating safety gap is provided on both sides of each of the first connecting portions and / or on both sides of each of the second connecting portions.

[0014] Furthermore, the adapter plate is connected to the end of the lamp panel.

[0015] Furthermore, the second connecting portion of the adapter plate extends out of the lamp plate, while the remaining portion overlaps with the lamp plate.

[0016] Furthermore, each of the first connection portions has at least one second connection portion electrically connected to it via the line layer.

[0017] The beneficial effects of this invention are as follows: An adapter plate is provided between the lamp board and the external wiring. The adapter plate and the lamp board have an overlapping portion, which strengthens the connection area and connection strength, and enhances the tensile force between the external wiring and the lamp board in the lateral, longitudinal, and various angle directions. This avoids the problem of LED strip solder pads detaching and delaminating due to repeated high-temperature soldering. Furthermore, the adapter plate allows cables to extend more easily from the side or vertical direction, instead of being limited to traditional axial wiring, facilitating installation in different scenarios. The adapter plate has at least two circuit layers, increasing current carrying capacity. Moreover, by designing different numbers of circuit layers, the conductive material, thickness, and width of each layer can be flexibly adjusted to meet the different power requirements of the LED strip.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the following detailed description of a cable-connected LED strip is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0031] Please refer to Figures 1-8. A light strip with a secure cable connection includes:

[0032] Light panel 100;

[0033] LED beads 200, a number of LED beads 200 are spaced apart on the lamp board 100;

[0034] The adapter board 300 includes a substrate layer 310 and at least two side circuit layers 320 disposed within the substrate layer 310. The adapter board 300 is provided with a plurality of first connecting portions 330 and a plurality of second connecting portions 340. The first connecting portions 330 and the second connecting portions 340 are electrically connected through the circuit layers 320. The lamp board 100 is welded to the first connecting portions 330 and the lamp board 100 has an overlapping portion with the substrate layer 310.

[0035] External wiring 400 is welded to the second connection part 340.

[0036] An adapter plate 300 is installed between the lamp board 100 and the external wiring 400. The adapter plate 300 has an overlapping portion with the lamp board 100, strengthening the connection area and connection strength. This enhances the lateral, longitudinal, and angular tensile forces between the external wiring 400 and the lamp board 100, preventing the LED strip solder pads from detaching and delaminating due to repeated high-temperature soldering. Furthermore, the adapter plate 300 allows cables to extend more easily from the side or vertical direction, rather than being limited to traditional axial wiring, facilitating installation in different scenarios. The adapter plate 300 has at least two circuit layers 320, increasing current carrying capacity. Through different numbers of circuit layers, the conductive material, thickness, and width of each layer can be flexibly adjusted to meet the varying power requirements of the LED strip.

[0037] Please refer to Figures 1-3. The external wiring 400 connects to the adapter plate 300 laterally or vertically. Lateral and vertical wiring reduces the overall length of the light strip, making it suitable for scenarios with limited installation space. As you can understand, please refer to Figure 4; axial wiring can also be used as needed.

[0038] Referring to Figures 5-8, the substrate layer 310 has a through-hole 360, which is filled with a conductor 361 for electrically connecting the circuit layers 320 at different heights. The conductor 361 can be filled with conductive materials such as copper paste or silver paste and solidified as needed.

[0039] Please refer to Figures 5-6. The first connecting part 330 is one of the following: a U-shaped hole opening to the end, a vertically penetrating through hole, an exposed solder joint groove, a welding protrusion, or a plane exposing the solder joint.

[0040] Referring to Figures 5-6, the second connecting part 340 is a U-shaped hole opening towards the end or a vertically penetrating through hole. This design method of using an open U-shaped hole or through hole can enhance the tensile strength during welding and improve the stability after welding.

[0041] Referring to Figures 5-8, an insulating safety interval 350 is provided on both sides of each first connecting portion 330 and / or on both sides of each second connecting portion 340. Providing the insulating safety interval 350 improves safety and prevents short circuits caused by excessively large weld points during welding. Preferably, the insulating safety interval 350 is directly formed from the outer substrate layer 310, and the forming method can be injection molding, cutting, compression molding, etc. In particular, the insulating safety interval 350 is a raised rib.

[0042] Please refer to Figures 1-4. The adapter plate 300 is connected to the end of the lamp panel 100. Alternatively, the wire can exit from the middle of the lamp panel 100 as needed.

[0043] Referring to Figures 1-4, the second connecting portion 340 of the adapter plate 300 extends out of the lamp plate 100, and the remaining portion overlaps with the lamp plate 100. Increasing the area of ​​the overlapping portion improves stability. Preferably, the overlapping portion of the adapter plate 300 and the lamp plate 100 can be reinforced and fixed by welding, gluing, or riveting.

[0044] Preferably, each first connection portion 330 has at least one second connection portion 340 electrically connected to it via the line layer 320. That is, each first connection portion 330 has at least one corresponding second connection portion 340. Preferably, there is a one-to-one correspondence between the first connection portion 330 and the second connection portion 340.

[0045] Understandably, the adapter board 300 can be designed with a regular or irregular shape according to the requirements of the LED light strip. The substrate layer 310 can be made of rigid or flexible materials, such as FPC, FR4, or aluminum, and the material of the welding adapter board 300 can be flexibly adjusted according to the requirements. Similarly, the light board 100 can also be made of rigid or flexible materials as needed to meet different requirements, such as commonly used FPC or aluminum.

[0046] Understandably, please refer to Figure 7. The substrate layer 310 can be a single layer wrapping the circuit layer 320, or, please refer to Figure 8, it can be a multi-layer composite circuit layer 320, depending on the selected material and requirements.

[0047] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0049] In summary, the present invention provides a light strip with a robust cable connection, enhancing the connection area and strength with the light panel, and increasing the tensile force between the external wiring and the light panel in the lateral, longitudinal, and various angles. This avoids the problems of detachment and delamination of LED light strip solder pads caused by repeated high-temperature soldering. Furthermore, the adapter plate allows the cable to extend more easily from the side or vertical direction, rather than being limited to the traditional axial cable exit, facilitating installation in different scenarios. Moreover, it is flexible and versatile; by designing different numbers of circuit layers, different materials, thicknesses, and widths of the circuit layers, and designing the shape and material of the substrate layer, it can meet different situations and adapt to various construction environment requirements.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
