[0002] In the field of LED floodlights, a good heat dissipation structure is often required to ensure the stable operation of the luminaires. During long-term lighting, heat dissipation design is often a key consideration to prevent LED lights from overheating and degrading. However, traditional LED floodlight heat dissipation structures often suffer from poor heat dissipation performance due to the materials used and rough manufacturing processes. This results in the LED lights' lifespan being shortened because heat cannot dissipate quickly during operation. This not only affects the stability of the lighting, causing flickering or reduced brightness, but also increases costs due to frequent luminaire replacements, thus reducing the overall cost-effectiveness of the floodlights. Utility Model Content

This solves the technical problem that traditional LED floodlight heat dissipation structures have poor heat dissipation performance and rough processing technology.

[0004] The purpose and function of this utility model's cold-forged pure aluminum heat dissipation LED floodlight structure are achieved through the following specific technical means:

[0005] A cold-forged pure aluminum heat dissipation LED floodlight structure includes a base, a heat dissipation shell on the base, a heat dissipation plate inside the heat dissipation shell, a lampshade mounted on the heat dissipation shell, the lampshade communicating with the heat dissipation shell, a retaining ring at the bottom of the lampshade, a retaining groove on the heat dissipation shell, the retaining ring being engaged in the retaining groove; a lamp disk inside the lampshade, a reflector on the lamp disk, the reflector being trumpet-shaped with its opening facing upwards, a cover plate mounted on the lampshade, a mounting groove at the bottom of the cover plate, a protective plate being engaged in the mounting groove, the protective plate being located between the cover plate and the lampshade.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 6 As shown, this utility model provides an LED floodlight structure with heat dissipation using cold-forged pure aluminum, including a base 11 for basic support. A heat dissipation shell 12 is mounted on the base 11, which not only protects the internal heat dissipation components but also assists in heat dissipation. A heat dissipation plate 13 is installed inside the heat dissipation shell 12, serving as the main heat dissipation element responsible for conducting away the heat generated by the lamp. A lampshade 14 is mounted on top of the heat dissipation shell 12, communicating with it to protect the internal lamp panel 16 and other components, and guiding the light outwards. A retaining ring 15 is provided at the bottom of the lampshade 14, and a retaining groove is formed on the heat dissipation shell 12. The retaining ring 15 engages with the groove, ensuring the lampshade 14 is securely mounted on the heat dissipation shell 12. The lamp panel 16, the core component for light emission, is placed inside the lampshade 14. A reflector 17 is provided on the lamp panel 16. The reflector 17 is trumpet-shaped with its opening facing upward, which can reflect and focus the light emitted by the lamp panel 16 to enhance the lighting effect. A cover plate 18 is installed on the top of the lamp shade 14. The bottom of the cover plate 18 has a mounting groove, in which a protective plate 19 is installed. The protective plate 19 is located between the cover plate 18 and the lamp shade 14, which protects the internal components without affecting the light transmission.

[0026] like Figure 2 , Figure 4As shown, the bottom of the heat sink 13 is provided with multiple sets of heat dissipation fins 21. The heat dissipation fins 21 increase the heat dissipation area, which helps heat to be dissipated into the surrounding air more quickly. Multiple sets of ventilation slots 22 are formed on the heat dissipation fins 21. The ventilation slots 22 are wavy and the multiple sets of ventilation slots 22 are arranged at equal intervals. This wavy design can disrupt the airflow, increase the contact time between the air and the heat dissipation fins 21, improve the heat dissipation efficiency, and allow the air to carry away heat more effectively during the flow.

[0027] The top of the heat sink 13 is connected to the bottom of the lamp panel 16, providing a direct path for heat conduction. A square groove 23 is formed on the top of the heat sink 13, and this groove is filled with thermal grease. The thermal grease fills the tiny gaps between the heat sink 13 and the lamp panel 16, reducing thermal resistance and allowing the heat generated by the lamp panel 16 to be transferred to the heat sink 13 more efficiently, and then dissipated through the heat dissipation fins 21.

[0028] Four sets of locking blocks 24 are provided inside the heat dissipation housing 12. Each pair of locking blocks 24 is located on both sides of the inner wall of the heat dissipation housing 12, and the locking blocks 24 are L-shaped. A mounting plate 25 is installed between the two sets of locking blocks 24. This structure provides mounting positions for other components and also enhances the stability of the internal structure of the heat dissipation housing 12.

[0029] like Figure 2 , Figure 6 As shown, a mounting slot 26 is provided on the top of the mounting plate 25 for mounting a cooling fan. Cooling grilles are provided on both sides of the mounting plate 25 and around the perimeter of the heat sink housing 12. When the cooling fan rotates, air enters the interior of the heat sink housing 12 through the cooling grilles, accelerating airflow, carrying away heat, improving heat dissipation, and ensuring the lamp maintains a suitable temperature during operation.

[0030] like Figures 2 to 6 As shown, the lampshade 14, heat dissipation housing 12, and base 11 are all made of pure aluminum and are processed by cold forging. During the cold forging process, the grain structure inside the pure aluminum changes, and the grains are refined and arranged more densely. This significantly improves the strength and hardness of the pure aluminum material, allowing it to better withstand external forces compared to its original state. For components such as the heat dissipation housing 12 and base 11 of the LED floodlight, the enhanced strength and hardness can effectively resist collisions and friction during daily use, extending the lifespan of the lamp. Pure aluminum has good thermal conductivity, which helps the lamp dissipate heat, and its relatively light weight makes it easy to install and use. The protective plate 19 is made of glass. Glass has good transparency, which can effectively protect the internal components while ensuring that light can pass through smoothly without affecting the lighting quality.

[0031] Multiple sets of support blocks 27 are provided on the inner wall of the lampshade 14. Two sets of support blocks 27 have multiple sets of mounting holes, and magnets 28 are installed in the mounting holes. These magnets 28 can help fix the reflector 17 inside the lampshade 14, making it convenient for users to adjust and use the lamp according to actual needs.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this cold-forged pure aluminum heat sink LED floodlight, the lamp panel 16 emits light upon power-up. The generated heat is transferred to the heat sink 13 via thermal grease, and then conducted from the heat sink 13 to the heat sink fins 21 at the bottom. The wavy ventilation slots 22 on the heat sink fins 21 allow air to carry away heat more effectively. At the same time, the cooling fan rotates, accelerating airflow within the heat sink housing 12 through the heat dissipation grille, enhancing the heat dissipation effect. The reflector 17 reflects and focuses the light emitted from the lamp panel 16, and the light is emitted through the protective plate 19 and the lampshade 14. The entire luminaire achieves efficient heat dissipation and good lighting effect through the coordinated work of its components, meeting the lighting needs of different scenarios.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
