Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, specifically relating to a modular, splicable LED light strip. Background Technology

[0002] LED light strips have been widely used in decorative lighting, advertising displays, home lighting, and landscape lighting due to their advantages such as energy saving, long lifespan, rich colors, and ease of shaping. Traditional LED light strips are usually supplied in fixed lengths (such as 1 meter or 5 meters per roll). Users need to cut and weld them according to the actual installation length, which is cumbersome, requires high technical skills, and can easily lead to damage to the entire strip or sections if the cutting or welding is incorrect.

[0003] To solve the problems of cutting and welding, some splicable LED light strips have appeared on the market. These light strips are typically spliced ​​in the following ways: Soldered wire connection: A wire is pre-installed, and the connection is achieved through soldering or screwing. However, this method still involves the inconvenience of soldering, and the connection points are fragile, requiring additional insulation and waterproofing.

[0004] Pin-and-socket type: Male and female plugs are installed at both ends of the light strip, and the connection is made by physical plugging and unplugging. The disadvantages are that the pins are prone to oxidation and bending, poor contact after repeated plugging and unplugging, and poor waterproof performance.

[0005] Existing splicing methods include snap-on modular light strips: connected by physical snaps, but this usually only solves the mechanical connection and does not fundamentally improve reliability, such as the modular LED light strip, system and construction process system disclosed in patent application CN221222422U.

[0006] Therefore, existing LED light strip technologies have significant shortcomings in terms of ease of splicing and reliability, and an innovative solution is urgently needed. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, please refer to Figures 1-2 The invention showcases a modular, splicable LED light strip, comprising a substrate 1, which is composed of multiple module substrates 101. Each module substrate 101 has a built-in microcircuit and LED beads 2 are mounted on it. The circuits of adjacent module substrates 101 are connected in series, so that after power is supplied through the line connection at the end, all the series-connected LED beads 2 will light up and be used.

[0028] The adjacent module substrates 101 are connected by a detachable splicing mechanism, which makes it convenient to flexibly splice the length according to different needs.

[0029] Specifically, this includes electrical connection mechanisms and mechanical connection mechanisms; The electrical connection mechanism includes "male" and "female" interfaces designed at both ends of each module, including electrical connection plug 102 and electrical connection interface 103. Any conventional connection can be selected from the market and will not be described in detail. This enables bidirectional splicing between any two modules, and electrical connection is achieved after plugging in.

[0030] The mechanical connection mechanism includes a first connection joint 104 and a second connection joint 105 distributed at the left and right ends of each module. The left and right ends are respectively designed with "male" and "female" interfaces, and the mechanical connection mechanism achieves stable connection.

[0031] Please see Figure 1 As a further embodiment, the substrate 1 is a flexible circuit board, which can be arranged according to needs. This is a conventional technology and will not be described in detail. The head end of the substrate 1 is connected to the connector 3 in the same way as the connection mechanism between the adjacent module substrate 101. The connector 3 is connected to the power line 4. The circuit design of the last module substrate 101 forms a loop. The power line 4 and the power supply are used to power the LED beads 2 of each module on the substrate 1 to emit light.

[0032] See Figure 2As a further embodiment, the mechanical connection mechanism is provided with two first connection joints 104 and two second connection joints 105 on the same side. The connection joints are preferably made of hard plastic or metal. In order to achieve stable connection and integral injection molding connection with the module substrate 101, they are preferably provided at the four corners of the module substrate 101, that is, two first connection joints 104 are provided on one side of a module substrate 101 and two second connection structures 105 are provided on the other side, so as to make the connection more stable.

[0033] See Figure 3 As a further embodiment, the specific connection method of the first connecting joint 104 and the second connecting joint 105 includes: a first connecting groove 106 provided on the first connecting joint 104; a retractable positioning member 107 provided in the first connecting groove 106; the positioning member 107 has a retractable structure; the second connecting joint 105 is provided with a groove into which the first connecting joint 104 can be inserted; after the first connecting joint 104 is inserted into the groove of the second connecting joint 105, the second connecting groove 108 in the second connecting joint 105 corresponds to the first connecting groove 106; and the positioning member 107 can partially extend into the second connecting groove 108, so that the positioning member 107 can lock the first connecting groove 106 and the second connecting groove 108, thereby realizing a mechanical connection.

[0034] See Figure 3 As a further embodiment, a compression spring 5 is also provided in the first connecting groove 106. The compression spring 5 realizes the squeezing force of the positioning member 107 after the second connecting groove 108 and the first connecting groove 106 are in place, so that the positioning member 107 is stuck between the first connecting groove 106 and the second connecting groove 108, and cannot be reset under the spring squeezing force, thus achieving a stable connection.

[0035] See Figure 2 As a further embodiment, both first connecting grooves 106 on the same side of the module substrate 101 are arranged outward, that is, the upper first connecting groove 106 faces upward and the lower first connecting groove 106 faces downward. In this way, even when the external shaking occurs, the positioning members 107 on both sides are squeezed in different directions by the spring and will not disengage from the second connecting groove 108 at the same time, thus achieving a locking connection.

[0036] See Figure 3 As a further embodiment, the second connecting joint 105 is also provided with a small hole 6, which is connected to the second connecting groove 108. This makes it very convenient to separate the parts when disassembly is required, simply insert an external needle rod into the small hole 6 to push the positioning member 107 back.

[0037] See Figures 3-4 As a further embodiment, a sealing plug 7 is installed on the small hole 6. The sealing plug 7 is made of silicone anti-slip material to achieve waterproof and dustproof sealing, and the anti-slip sealing is stable.

[0038] Usage process: According to the lighting length and functional requirements, the user selects the corresponding number of module substrates 101, 1 connector 3 and power cord 4, and assembles all the modules in sequence through standardized electrical and mechanical connection mechanisms, like building blocks. The front end of the substrate 1 is connected to the connector 3 and power cord 4 in the same way as the connection mechanism between adjacent module substrates 101. The circuit design of the last module substrate 101 forms a loop, and the power cord 4 and power supply are used to make the LED beads 2 of each module on the substrate 1 light up.
