Description

Technical Field

[0001] This application belongs to the technical field of LED lights, and particularly relates to a flexible three-dimensional light effect type LED neon light. Background Art

[0002] The LED neon lights on the market include a plurality of LED light-emitting components arranged in sequence. Each light-emitting component is provided with a plurality of LED patches arranged at equal intervals along the length direction of the light strip. Both ends of the light-emitting component need to be connected to a positive wire and a negative wire respectively.

[0003] The patent with the publication number CN218819741 U discloses a neon light strip, which includes: a light source component, including a strip-shaped circuit board and a light-emitting chip arranged on the strip-shaped circuit board; a sleeve body, which is transparently arranged and has a receiving cavity. The receiving cavity has a first side wall and a light-transmitting wall opposite to the first side wall. The first side wall is provided with a first card slot, and the strip-shaped circuit board is received in the first card slot, and the light-emitting chip faces the light-transmitting wall; wherein, the sleeve body further has a refractive cavity, the refractive cavity extends side by side with the receiving cavity, the refractive cavity is arranged on the side of the light-transmitting wall facing away from the first side wall, and in the connection direction of the refractive cavity and the receiving cavity, the width of the refractive cavity is greater than the width of the receiving cavity.

[0004] The above patent achieves a three-dimensional lighting effect by setting a refractive cavity, so that when the light emits outward, it will enter the refractive cavity and undergo multiple reflections and refractions. However, in the actual use process, due to its hollow interior, the waterproof performance is poor, which easily causes external rainwater to enter the interior. In the light case, it will affect the irradiation, and in the severe case, it will cause damage, so improvement is needed. Utility Model Content

[0005] The purpose of this application is to provide a flexible three-dimensional light effect type LED neon light, which can solve the above problems.

[0006] The purpose of this application is to provide a flexible three-dimensional light effect type LED neon light, including:

[0007] A flexible circuit board, on which LED lamp beads are welded, and a wire is connected to the flexible circuit board;

[0008] A housing, including a lamp housing and an end cover. The flexible circuit board is arranged in the lamp housing, and the wire passes through the lamp housing and extends outside the lamp housing;

[0009] A waterproof mechanism, arranged between the end cover and the housing;

[0010] Wherein, the end cover is provided with a wire passing hole for the wire to pass through. The wire passes through the waterproof mechanism and the end cover and then extends to the outside.

[0011] Adopting the above-mentioned flexible three-dimensional light effect type LED neon light, the LED lamp beads are welded on the flexible circuit board, which can produce a bright, vivid, continuous and uniform light-emitting effect. The design of the flexible circuit board enables the LED neon light to be bent, twisted and installed on the surfaces of various curves, angles and shapes to meet different decoration requirements. The waterproof mechanism is arranged between the end cover and the shell to ensure that when the wire extends to the outside after passing through the waterproof mechanism and the end cover, it still has waterproof performance, and is suitable for outdoor lighting environments and facilities.

[0012] Further, the waterproof mechanism includes:

[0013] A support shell, one end of which is provided with a mounting groove adapted to the lamp shell, and the other end is connected to the end cover;

[0014] A support ring, arranged inside the support shell;

[0015] A first sealing ring, arranged in the mounting groove;

[0016] Among them, threaded holes corresponding to each other are provided on the support shell, the support ring and the lamp shell, and the support shell, the support ring and the lamp shell are connected by bolts.

[0017] The support shell: As the main framework of the waterproof mechanism, one end of it is provided with a mounting groove adapted to the lamp shell to ensure the stable installation of the lamp shell, and the other end is connected to the end cover, thus forming a closed waterproof environment. The support ring is arranged inside the support shell to form an internal support framework, which enhances the stability of the overall structure and provides support for the installation of subsequent structures at the same time. The first sealing ring is installed in the mounting groove. When the support shell is combined with the lamp shell, the sealing ring plays a sealing role to prevent moisture from seeping in from the mounting groove.

[0018] In this application, the support shell, the support ring and the lamp shell are connected by bolts and are provided with corresponding threaded holes, which can ensure a tight connection and is also convenient for installation and disassembly. When the support shell is tightly combined with the lamp shell, the sealing ring can also fill the possible tiny gaps, effectively preventing moisture from seeping through the gaps.

[0019] Further: The waterproof mechanism further includes:

[0020] A second sealing ring, arranged on the support ring;

[0021] A positioning plate, arranged on the second sealing ring, and a first through hole for the wire to pass through is provided on the positioning plate;

[0022] Among them, the positioning plate and the support ring are connected by bolts.

[0023] The second sealing ring is placed on the support ring, which can form an additional sealing structure, thus improving the waterproof performance of the entire waterproof mechanism. The positioning plate is arranged on the second sealing ring, and a first through hole for the wire to pass through is arranged thereon, enabling the wire to pass through the waterproof mechanism stably. The positioning plate and the support ring are connected by bolts, and this connection method ensures the stability of the positioning plate. Through the arrangement of the first sealing ring and the second sealing ring, a double sealing layer is formed between the lamp housing, the support housing and the support ring, greatly enhancing the waterproof effect of the waterproof mechanism, enabling the LED neon lamp to work in a more severe environment, such as outdoor high-brightness environments and facilities.

[0024] Furthermore, a lower limit ring is arranged on the positioning plate, an upper limit ring corresponding to the lower limit ring is arranged on the end cover, a rubber sleeve is arranged between the upper limit ring and the lower limit ring, and a guiding hole for the wire to pass through is arranged at the center of the rubber sleeve, and the guiding hole is communicated with the through hole and the wire passing hole.

[0025] A lower limit ring is arranged on the positioning plate, and this limit ring provides a fixed bottom support for the rubber sleeve. An upper limit ring corresponding to the lower limit ring is arranged on the end cover, and the two limit rings jointly ensure the stable position of the rubber sleeve in the vertical direction. The rubber sleeve is arranged between the upper limit ring and the lower limit ring, forming a tight waterproof barrier, which has good elasticity and waterproof performance and can effectively prevent water penetration. A guiding hole for the wire to pass through is arranged at the center of the rubber sleeve, and this guiding hole is communicated with the through hole on the positioning plate and the wire passing hole on the end cover, forming a complete wire channel.

[0026] Through the above design, when the wire passes through the waterproof mechanism, it first passes through the through hole on the positioning plate, then enters the guiding hole of the rubber sleeve, and finally extends to the outside through the wire passing hole on the end cover. During the whole process, the wire is tightly wrapped by the rubber sleeve, thus ensuring the isolation between the wire and the external environment. The design of the lower limit ring and the upper limit ring avoids the displacement or deformation of the rubber sleeve caused by reasons such as wire pulling or vibration. The elasticity and waterproof performance of the rubber sleeve itself, as well as its tight fit with the limit rings, jointly form a reliable waterproof barrier, effectively preventing water from seeping into the lamp housing through the wire channel.

[0027] Furthermore, a plurality of guide posts are arranged on the support ring, and positioning holes adapted to the guide posts are arranged on both the second sealing ring and the positioning plate.

[0028] By providing a number of guide posts on the support ring, it can ensure that the second sealing ring and the positioning plate can be accurately aligned and fixed during assembly, thereby enhancing the stability and sealing performance of the entire waterproof mechanism. The second sealing ring and the positioning plate are provided with positioning holes adapted to the guide posts on the support ring, ensuring that the second sealing ring and the positioning plate can be accurately installed on the support ring, and through the guidance of the guide posts, a tight fit with the support ring is achieved.

[0029] Furthermore, a third sealing ring is provided between the end cap and the support shell, and the end cap and the support shell are connected by threads.

[0030] To further enhance the waterproof effect, a third sealing ring is added between the end cap and the support shell and fixed by threaded connection, ensuring a tight connection between the end cap and the support shell and providing an additional waterproof barrier. The third sealing ring is made of an elastic material such as rubber or silica gel, having good sealing performance and weather resistance. When the end cap and the support shell are tightly fitted by threaded connection, the third sealing ring is compressed and fills the tiny gaps between them, thereby effectively preventing moisture from seeping in through these gaps.

[0031] The beneficial effects of this application are as follows:

[0032] 1. The LED lamp beads are welded on the flexible circuit board, capable of producing bright, vivid, continuous and uniform light-emitting effects. The design of the flexible circuit board enables the LED neon lights to be bent, twisted and installed on surfaces of various curves, angles and shapes, adapting to different decoration needs;

[0033] 2. The waterproof mechanism is arranged between the end cap and the housing, ensuring that when the wire extends to the outside after passing through the waterproof mechanism and the end cap, it still has waterproof performance, suitable for outdoor lighting environments and facilities;

[0034] 3. Through the arrangement of the first sealing ring and the second sealing ring, the waterproof mechanism forms a double sealing layer between the lamp housing, the support shell and the support ring, greatly enhancing the waterproof effect of the waterproof mechanism, enabling the LED neon lights to work in more severe environments, such as outdoor high-lighting environments and facilities.

[0060] As Figure 3 shown, the waterproof mechanism 300 further includes:

[0061] A second sealing ring 340, disposed on the support ring 320;

[0062] A positioning plate 350, disposed on the second sealing ring 340, and a first through hole 351 for the wire 120 to pass through is provided on the positioning plate 350;

[0063] Wherein, the positioning plate 350 and the support ring 320 are connected by bolts.

[0064] In the embodiment of the present application, the second sealing ring 340 is placed on the support ring 320, which can form an additional sealing structure, thereby improving the waterproof performance of the entire waterproof mechanism 300. The positioning plate 350 is arranged on the second sealing ring 340, and a first through hole 351 for the wire 120 to pass through is provided thereon, so that the wire 120 can stably pass through the waterproof mechanism 300. The positioning plate 350 and the support ring 320 are connected by bolts, and this connection method ensures the stability of the positioning plate 350. Through the arrangement of the first sealing ring 330 and the second sealing ring 340, the waterproof mechanism 300 forms a double sealing layer between the lamp housing 210, the support housing 310 and the support ring 320, greatly enhancing the waterproof effect of the waterproof mechanism 300, enabling the LED neon light to work in a more severe environment, such as outdoor high-brightness environments and facilities.
