Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and more specifically, to a high-strength military-grade die-cast aluminum LED lamp housing. Background Technology

[0002] In the military field, LED lights, as important lighting equipment, need to maintain stable operation in various extreme environments. This places extremely high demands on the performance of their housings. High strength, good heat dissipation, reliable protection, and convenient assembly are indispensable characteristics of military LED light housings.

[0003] The invention patent with authorization announcement number CN117553258B discloses an LED lighting power supply housing structure, including several LED power supply light groups and a container power distribution unit. The LED power supply light groups are arranged in a ring at equal intervals. The LED power supply light groups are installed in a mounting cavity at the bottom of the container power distribution unit. The side of the mounting cavity is also magnetically connected to a protective cover. The container power distribution unit is also provided with a power distribution assembly structure, which is installed at the bottom of the container power distribution unit and connected by several bolts. This invention, while providing illumination through the LED power supply light groups, also attracts mosquitoes in the room and other environments, drawing them into the interior of the arc insect-killing component to eliminate and kill the mosquitoes, reducing the probability of mosquitoes disturbing the user's rest. The LED power supply light groups for illumination and the battery pack for power supply are located in two separate cavities, which facilitates heat dissipation.

[0004] While the aforementioned technical solutions offer corresponding advantages, existing LED lamp housings have some shortcomings in military applications. For example, some housings employ a split, spliced ​​structure, resulting in weak joints that are prone to cracking and deformation under impact, vibration, or other external forces, making them unable to withstand the high-intensity forces of a military environment. Furthermore, gaps in the joints allow moisture and dust to penetrate, compromising protective performance and affecting the normal operation of the internal LED components. Additionally, the heat dissipation structure is poorly designed, with limited heat dissipation area and low efficiency, preventing timely dissipation of heat generated during LED operation, accelerating the aging of internal components, and shortening the lamp's lifespan. Therefore, we propose a high-strength military-grade die-cast aluminum LED lamp housing. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength military-grade die-cast aluminum LED lamp housing to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength military-grade die-cast aluminum LED light housing includes an integrated die-cast aluminum housing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a high-strength military-grade die-cast aluminum LED lamp housing, including an integrated die-cast aluminum housing 1. A transparent protective plate 11 is detachably installed on the bottom surface of the integrated die-cast aluminum housing 1. An upper frame 14 is integrally formed on the top of the integrated die-cast aluminum housing 1. A die-cast top cover 17 is detachably installed on the top surface of the upper frame 14. Multiple heat dissipation fins 19 are fixedly installed on the side plates of the integrated die-cast aluminum housing 1, the upper frame 14, and the die-cast top cover 17. Two symmetrical internal accessory fixing plates 15 are fixedly installed on the inner wall of the upper frame 14. The integrated die-cast aluminum housing 1 and the upper frame 14 are integrally formed to improve the overall strength. The heat dissipation fins 19 enhance heat dissipation. The internal accessory fixing plates 15 facilitate the installation of accessories, thereby improving the overall performance of the housing and achieving the requirements of high strength and easy assembly for military LED lamp housings, thus meeting the requirements for use in military environments.

[0031] In this embodiment, the integrated die-cast aluminum shell 1 can be made of die-cast aluminum alloy material to improve its strength. This aluminum alloy material contains a specific proportion of alloying elements, including 6%–9% silicon, 0.8%–1.5% magnesium, 0.5%–1.2% copper, and iron content controlled below 0.3%. The remainder is aluminum and a small amount of unavoidable impurities. This alloy composition design gives the die-cast aluminum material high strength, good corrosion resistance, and thermal conductivity. By optimizing the alloy ratio, the yield strength and tensile strength of the material are improved, enabling it to withstand greater external impacts and extrusions without easily deforming or cracking. Simultaneously, the interaction of elements in the alloy forms a dense oxide film, effectively improving the material's corrosion resistance and allowing for long-term use in harsh environments such as humid conditions and corrosive gases.

[0032] In this embodiment, a bottom fixing frame 10 is fixedly installed at the bottom end of the integrated die-cast aluminum shell 1, and a side frame 12 is fixedly installed on the side of the transparent protective plate 11. The side frame 12 is detachably installed on the bottom surface of the bottom fixing frame 10 by multiple fastening screws, making the installation and removal of the transparent protective plate 11 more convenient, facilitating the maintenance or replacement of the transparent protective plate 11 of the internal components in the future, thereby improving the convenience of equipment maintenance; and the transparent protective plate 11 is made of transparent material for normal light transmission operation.

[0033] like Figure 2As shown, a first sealing ring 13 is provided between the side frame 12 and the bottom fixing frame 10. The first sealing ring 13 is embedded in both the side frame 12 and the bottom fixing frame 10, which enhances the sealing performance at the connection between the transparent protective plate 11 and the integrated die-cast aluminum shell 1, effectively preventing moisture and dust from entering, making the shell more protective and achieving the effect of protecting the internal components.

[0034] like Figure 2 As shown, the inner component fixing plate 15 is provided with multiple screw holes for component installation, and a central gap hole 151 is provided between the two inner component fixing plates 15. The screw holes facilitate the secure installation of components, and the central gap hole 151 provides installation space and facilitates internal air circulation, making the component installation more secure and promoting heat dissipation, thereby improving the stability and heat dissipation of the equipment.

[0035] like Figure 2 As shown, a lower flange 16 is fixedly installed at the top of the upper frame 14, and an upper flange 171 is fixedly installed at the bottom of the die-cast top cover 17. The upper flange 171 and the lower flange 16 are detachably connected, making it easier to install and remove the die-cast top cover 17, facilitating internal maintenance and improving the convenience of equipment maintenance.

[0036] like Figure 2 As shown, a second sealing ring 18 is embedded between the lower flange 16 and the upper flange 171. The distance between two adjacent heat dissipation fins 19 is between 0.5cm and 1.5cm. The second sealing ring 18 enhances the sealing performance, and the reasonably spaced heat dissipation fins 19 ensure heat dissipation efficiency, making the sealing and heat dissipation effects of the outer shell better, thereby improving the protection and heat dissipation performance of the equipment.

[0037] like Figure 1 and Figure 3 As shown, a wiring conduit 2 is fixedly installed on the side plate of the upper frame 14. The wiring conduit 2 is set at a downward inclination of 45° to 60°. The inclination angle can reduce the entry of rainwater and make it difficult for rainwater to flow into the inside of the outer casing along the wiring conduit 2, thereby enhancing the waterproof performance of the outer casing and achieving the effect of protecting the internal components.

[0038] like Figure 3 As shown, an inner rubber sleeve 20 is fixedly installed on the inner wall of the wiring conduit 2, and a wiring hole 22 is fixedly installed on the inner wall of the inner rubber sleeve 20. A conical chamber 21 is provided on the cavity wall of the wiring hole 22 near the opening of the upper frame 14. The conical chamber 21 is funnel-shaped, which makes it easier for the cable to be inserted and pass through the end of the wiring hole 22. The inner rubber sleeve 20 and the wiring hole 22 can be sealed with waterproof glue to the cable, making the wiring operation more convenient and the sealing effect better, thereby improving the convenience and sealing of wiring.

[0039] When using the high-strength military-grade die-cast aluminum LED lamp housing of this utility model, firstly, through the screw holes on the inner accessory fixing plate 15, install the LED lamp related accessories on the inner accessory fixing plate 15 inside the upper frame 14 of the integrated die-cast aluminum housing 1. The central gap hole 151 is used to reserve space and promote air circulation. Then, the side frame 12 of the transparent protective plate 11 is installed on the bottom fixing frame 10 at the bottom end of the integrated die-cast aluminum housing 1 with fastening screws to ensure that the first sealing ring 13 is tightly fitted and sealed.

[0040] Subsequently, the cable is passed through the conical cavity 21 of the wiring conduit 2 from the inside to the outside, and sealed with waterproof glue inside the wiring conduit 2. Then, the upper flange 171 of the die-cast top cover 17 is connected to the lower flange 16 of the upper frame 14, and the second sealing ring 18 is fitted. During use, the heat dissipation fins 19 dissipate heat.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
