Description

Technical Field

[0001] The present application relates to the field of lighting technology, and more specifically to the field of fireworks lamp technology. Background Art

[0002] Fireworks lights, as a special lighting device, are popular among people for their unique visual effects and dynamic changes. However, traditional firework lights mostly use rigid circuit boards and fixed structures, which not only limits their design flexibility but also brings many inconveniences during transportation, storage, and use.

[0003] Plug-in designs are a potential solution to this problem, but they can easily lead to poor contact, affecting circuit stability. Furthermore, waterproofing the plug-in area is difficult. Utility Model Content

[0004] In response to the above problems, the present application proposes a firework lamp, which aims to apply flexible FPC (Flexible Printed Circuit) to achieve a foldable firework lamp with good waterproof performance.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] A firework lamp comprises a positioning plate, a fixing cover engaged with the positioning plate, a plurality of transparent lamp tubes distributed in a ring shape on the positioning plate, and a flexible FPC passing through both ends of the transparent lamp tubes;

[0007] The transparent lamp is connected to the positioning plate via a rotating cover on one side of the positioning plate, and the rotating cover rotates in the opposite direction of the fixed cover;

[0008] A lamp board is provided in the middle of the positioning plate, the lamp board is connected to one end of the flexible FPC, and a sealing ring is provided on the outer periphery of the lamp board.

[0009] This application utilizes a flexible FPC, combined with a rotating cover that allows the transparent light tube to rotate relative to the positioning plate, allowing the firework lamp to fold into a compact shape when not in use, significantly saving space. Furthermore, the flexible FPC's flex resistance ensures the circuit remains functional even after multiple folds, extending the lifespan of the firework lamp. Furthermore, the circular mounting structure, combined with a sealing ring around the outer perimeter of the light panel, achieves waterproofing with a simple structure.

[0010] In some possible implementations, an upper cover with a threaded structure is provided on one side of the rotating cover of the positioning plate in the rotation direction.

[0011] In a preferred embodiment, the upper cover is provided with a sealing ring capable of covering the folded transparent lamp tube.

[0012] In some possible embodiments, the rotating cover is provided with a rotating shaft, and the positioning plate and the fixed cover engage to form an axis hole for the rotating shaft. Thus, when installing the entire rotating cover and the transparent lamp, simply place them neatly and then snap on the fixed cover to complete the installation. This makes the installation and removal of the firework lamp simpler and faster, reducing the time and cost of manual operation.

[0013] In some possible implementations, the invention further includes a plug installed on a side of the transparent light tube away from the positioning plate.

[0014] In some possible implementations, the flexible FPC is provided with an outward folded portion on one side of the plug, and the plug covers the folded portion to form a sealing portion.

[0015] In some possible implementations, at least one of the transparent tubes is equipped with an extension tube on the side away from the positioning plate. The transparent tube and the extension tube are connected by a connecting hose. This design allows the extension tube to be relatively long, creating a rising effect for the fireworks. Furthermore, the hose connection allows the extension tube to rotate 180° relative to the transparent tube, allowing for simultaneous folding.

[0016] In some preferred embodiments, a fastening cover for fixing the transparent light tube at the connecting hose is further included, and the transparent light tube can be fixed by covering the fastening cover during use.

[0017] In some possible implementations, at least one of the transparent light tubes is provided with a hook on a side away from the positioning plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following examples further illustrate the features of the present application and other related features to facilitate understanding by those skilled in the art:

[0032] In this description, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediary, or internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this case.

[0033] It should be further explained that the terms "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] Please refer to Figure 1 , is a schematic diagram of the fireworks light of the present application. Transparent light tubes 2 are evenly arranged around the periphery of a central hub 1. Each transparent light tube 2 is equipped with an LED light strip, simulating the effect of exploding fireworks. Because the fireworks light of the present application is a foldable design, the LED light strip preferably utilizes a flexible FPC (Flexible Printed Circuit), which runs through both ends of the transparent light tubes 2, with one end connected to the central hub 1.

[0035] Flexible FPC is thin, light, flexible, and bend-resistant, enabling the foldable design of firework lights, which not only facilitates transportation and storage, but also significantly improves their reliability and durability during use.

[0036] Further, if Figure 1The transparent light tube 2 at the lower end is connected to an extension light tube 3. The connection design of the extension light tube 3 and the transparent light tube 2 can form a relatively long light tube, which can achieve the effect of fireworks rising. Preferably, the extension light tube 3 and the transparent light tube 2 are foldable.

[0037] Correspondingly, in Figure 1 The upper end of the transparent light tube 2 is provided with a hook 4, which can be hung on the wall. In other words, the hook 4 and the extension light tube 3 are both arranged on the side of the transparent light tube 2 away from the central hub 1. Of course, the entire firework light can also be directly set up upright or attached to the wall for use.

[0038] The following is a detailed description of its specific implementation method combined with local details. Figure 2 and Figure 3 The central hub 1 includes a positioning plate 11 and a fixed cover 12 that is engaged with the positioning plate 11. The transparent light tube 2 is actually installed on the positioning plate 11. When connected, the transparent light tube 2 is connected to the positioning plate 11 on one side through the rotating cover 21. The rotating cover 21 and the transparent light tube 2 are fixedly connected. The rotating cover 21 can rotate in the opposite direction of the fixed cover 12, that is, it can drive the transparent light tube 2 to gather in the opposite direction of the fixed cover 12. The rotating angle of the rotating cover 21 is 90 degrees. Please refer to the effect diagram after rotation. Figure 11 and Figure 12 .

[0039] Please continue to refer to Figure 2 On the side of the rotation direction of the rotating cover 21 of the positioning plate 11, there is an upper cover 5, which is installed on the positioning plate 11 by a threaded structure. When used as a fireworks light, the upper cover 5 can prevent the rotating cover 21 from rotating. Please refer to Figure 11 and Figure 13 When folded, the sealing ring 51 provided inside the upper cover 5 can cover the folded transparent lamp tube 2 and can also be used as a cover for storage.

[0040] Please refer to Figure 4 、 Figure 5 、 Figure 6 .in Figure 5 is the viewing angle after the fixed cover 12 is hidden, and Figure 6 This is the opposite viewing angle after the positioning plate 11 is hidden. Figure 5 In the middle of the positioning plate 11, a light board 6, i.e., a control and power supply part, is provided. A microphone 61 is provided in the middle of the light board 6 to simulate the sound effect of fireworks. Correspondingly, a sound outlet 121 is provided in the middle of the fixing cover 12.

[0041] The light board 6 is connected to one end of the flexible FPC 22 by welding, and a sealing ring 7 is provided on the periphery of the light board 6. When the fixing cover 12 and the positioning plate 11 are buckled together, the sealing ring 7 can be squeezed to achieve a waterproof effect, which can achieve IP4* waterproof.

[0042] The rotating cover 21 is provided with a rotating shaft 211, and the axial hole of the rotating shaft 211 is formed when the positioning plate 11 and the fixed cover 12 are buckled together. Figure 4 Specifically, a groove 122 can be formed in the fixed cover 12 at a position corresponding to the rotating shaft 211, and a corresponding groove can be formed in the positioning plate 11, which engages to form an axis hole. In this way, after the entire rotating cover 21 and transparent lamp 2 are neatly arranged, the fixed cover 12 is snapped on to complete the installation. This makes the installation and removal of the firework lamp simpler and faster, reducing the time and cost of manual operation.

[0043] Please refer to Figure 7 and Figure 8 A plug 23 is provided on the side of the transparent lamp tube 2 away from the positioning plate 11. Specifically, the flexible FPC 22 has a folded portion 221 extending outward on one side of the plug 23. This portion extends outward from the outside of the transparent lamp tube 2 and folds back. The plug 23 covers the folded portion 221 and forms a sealing portion 231 on its exterior for gluing and securing.

[0044] Please refer to Figure 9 and Figure 10 The transparent lamp tube 2 and the extension lamp tube 3 are connected by a flexible connection. Specifically, a connecting hose 8 connects one end of the transparent lamp tube 2 to one end of the extension lamp tube 3. The connecting hose 8 allows the extension lamp tube 3 to rotate 180 degrees relative to the transparent lamp tube 2, allowing for synchronous folding.

[0045] Furthermore, a fastening cover 81 is provided at the connecting hose 8. The fastening cover 81 may be made of a hard material and may fix the transparent lamp tube 2 and the extension lamp tube 3 at the connecting hose 8 so as to maintain a straight state.

[0046] As mentioned above, this case protects a type of firework lamp, and all technical solutions that are the same or similar to those in this case should be deemed to fall within the scope of protection of this case.
