Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a modular splicing lighting fixture for LED full-screen displays. Background Technology

[0002] With the rapid development of LED lighting technology, it has been widely used in various scenarios such as indoor and outdoor lighting, commercial displays, large venue lighting, and outdoor advertising screens due to its advantages such as low energy consumption, long lifespan, high luminous efficiency, and fast response speed. Full-screen design to reduce bezel obstruction and improve the integrity and aesthetics of lighting or display, as well as modular splicing to flexibly combine lighting units of different sizes according to scenario requirements, have become important development trends for LED lighting fixtures. However, traditional modules often have obvious bezels, which can easily create dark areas or visual breaks between adjacent modules after splicing, making it difficult to achieve a true "full-screen" effect and affecting the continuity and aesthetics of lighting or display. In addition, the large amount of heat generated by LED light sources during operation can easily accumulate in high-power or multi-module splicing scenarios, and existing heat sinks mostly use a single fin structure with limited heat dissipation area. Utility Model Content

[0014] 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.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a modular splicing light fixture for a full-screen LED display.

[0016] Example 1: Combination Figures 1-5 As shown, the present invention provides an LED full-screen modular splicing lamp, including a power supply box 1, a heat sink 2 and a light source module. The full screen emits light, which is softer. Unlike traditional modules, it has no frame and has a beautiful appearance. It is easy to splice and there is no dark area in the middle after splicing multiple modules. A connecting wire 10 is also connected to the radiator 2. A waterproof connector 11 is installed at the connection between the radiator 2 and the connecting wire 10. A breather valve 12 is also threaded onto the radiator 2. A wire hole 9 is opened on the outside of the power box 1. The connecting wire 10 is inserted into the power box 1 through the wire hole 9 and connected to its internal electrical components. The breather valve 12 prevents the sealing failure caused by air pressure difference. The double protection improves the waterproof performance of the lamp and is suitable for humid environments.

[0017] Specifically, both sides of the power box 1 are connected to the connecting bracket 5 by bolts. The connecting bracket 5 has an adjustable installation angle slot 7, which allows the installation angle of the lamp to be flexibly adjusted to adapt to different lighting angle requirements and make it more practical. The two connecting brackets 5 are connected to the mounting bracket 4 by bolts. The mounting bracket 4 has an installation slot 6.

[0018] Furthermore, the light source module includes a light source plate 13 installed at the bottom of the heat sink 2 by screws 14. A lens 3 is installed on the heat sink 2 by clips 15. The light source plate 13 is located inside the lens 3. The light source plate 13 is fixed to the bottom of the heat sink 2 by screws 14 to ensure that the light source is installed stably and fits tightly against the heat sink 2, which facilitates heat conduction. The lens 3 is connected to the heat sink 2 by clips 15 and wraps the light source plate 13 inside, which serves to focus the light and protect the light source plate 13.

[0019] As can be seen from the embodiment, by setting heat dissipation fins 16 on the radiator 2 to expand the heat dissipation contact area, the heat of the light source can be dissipated quickly when it is working; the waterproof connector 11 seals the connection between the connecting wire 10 and the radiator 2, the breather valve 12 balances the air pressure inside and outside the lamp, and the wire hole 9 provides a passage for the connecting wire 10 to pass through, so that the connecting wire 10 can be stably connected to the electrical components inside the power supply box 1 to form a complete electrical circuit.

[0020] Example 2: Combination Figures 1-3As shown, based on Embodiment 1, multiple heat dissipation fins 16 are fixedly connected to the radiator 2. By increasing the number of heat dissipation fins 16, the contact area between the radiator 2 and the air is further expanded, accelerating heat conduction and convection heat dissipation. A reinforcing column 18 is fixedly connected at the connection between the heat dissipation fins 16 and the radiator 2. The structural support of the reinforcing column 18 is used to strengthen the connection strength between the fins and the radiator 2, and to prevent the fins from deforming or falling off due to stress or thermal expansion and contraction.

[0021] Specifically, the heat sink 2 has multiple module splicing holes 17 on its outer side. The module splicing holes 17 provide standardized connection points for the modular splicing of the lamps, making it easy to flexibly combine and splice them into lighting arrays of different sizes according to the lighting scene requirements, and adapt to diverse lighting needs.

[0022] Furthermore, the power supply box 1 has multiple heat dissipation holes 8. The heat generated by the electrical components inside the power supply box 1 can be exchanged with the outside air through the heat dissipation holes, so as to achieve natural heat dissipation. The distribution design of multiple heat dissipation holes can optimize the air circulation path and improve the uniformity of heat dissipation.

[0023] As can be seen from the above embodiments: First, prepare the light source module assembly, fix the light source board 13 to the bottom of the heat sink 2 with screws 14, ensuring that the light source board 13 and the heat sink 2 are tightly fitted to facilitate heat conduction. Then, install the lens 3 on the heat sink 2 with clips 15, so that the light source board 13 is located inside the lens 3, using the lens 3 to focus light and protect the light source board 13. Next, connect the connecting wire 10 to the heat sink 2, and install a waterproof connector 11 at the connection between the connecting wire 10 and the heat sink 2 to achieve sealing protection. At the same time, thread a breather valve 12 is connected to the heat sink 2 to balance the internal and external air pressure. After that, process the power supply box 1, insert the connecting wire 10 on the heat sink 2 into the box through the wire hole 9 on the outside of the power supply box 1, and connect it to the power supply box. The internal electrical components of box 1 are connected to form a complete electrical circuit. Multiple power heat dissipation holes 8 are pre-fabricated on the power box 1 to promote internal heat dissipation. Then, the mounting bracket 4 is assembled. The connecting bracket 5 is fixed to both sides of the power box 1 with bolts. After adjusting the angle using the adjustable mounting angle slot 7 on the connecting bracket 5, the mounting bracket 4 is connected to the two connecting brackets 5 with bolts, so that the mounting slot 6 on the mounting bracket 4 can be used to fix it to the mounting surface. Finally, if multiple modules need to be spliced, multiple lamps are precisely connected and fixed through the module splicing hole 17 on the outside of the heat sink 2 using connectors to form a frameless, dark-zone-free full-screen lighting unit, completing the assembly and installation of the LED full-screen modular splicing lamps.
