Abstract
Description
Technical Field
[0001] This utility model belongs to the field of linkage door technology, and in particular relates to a simple and reasonable waterproof floodlight body structure. Background Technology
[0002] Floodlights are lighting fixtures that provide higher illuminance to the illuminated surface than the surrounding environment; also known as spotlights, they are primarily used in locations requiring long-term, large-area operation, such as building outlines, stadiums, overpasses, monuments, parks, and flower beds. As these application scenarios indicate, floodlights typically operate at high power for extended periods. During continuous operation, they inevitably generate high heat, which continuously increases the lamp body's temperature. Prolonged exposure to high temperatures leads to increased resistance in electrical components, resulting in greater energy loss. Furthermore, the high temperature degrades the performance of the electrical components, reducing their lifespan. While externalizing the driver to the housing can reduce its impact on the light source module's temperature, this design compromises protection, and the separate design is inconvenient for packaging and transportation.
[0003] Therefore, it is necessary to develop a floodlight that not only has the basic waterproof function required for outdoor lighting, but also has advantages in terms of simplified structure, such as ease of production, assembly, use, and heat dissipation. Utility Model Content
[0004] This utility model provides a simple and reasonable waterproof floodlight body structure to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A simple and reasonable waterproof floodlight body structure includes a solar panel housing and a lampshade. The solar panel housing is characterized by having a cavity and a first auxiliary support arm. The cavity has a cable outlet for a battery to be placed and a power cable to be led out. Multiple heat dissipation ridges are integrally formed on the back of the solar panel housing. The front of the solar panel housing is a recessed plane to accommodate the solar panel. The solar panel is electrically connected to the battery in the cavity. Multiple independent lenses are integrally formed on the inner side of the lampshade. The inner edge of the lampshade is surrounded by a mounting groove for a sealing ring and a protective groove for waterproof adhesive filling. An LED-embedded lamp plate is mounted on the lampshade with the aid of screws and waterproof adhesive. A second auxiliary support arm is integrally formed on the lampshade. The solar panel housing and the lampshade are movably assembled together via their respective auxiliary supports and connecting parts.
[0007] Preferably, the lampshade has a molded cavity.
[0008] Preferably, the protective groove is also designed with auxiliary guide posts to cooperate with screws for positioning and assembling to reinforce the lamp panel.
[0009] Preferably, the outlet hole is equipped with a waterproof plug.
[0010] Compared to existing technologies, the advantages of this utility model are as follows: This utility model simplifies the structure of the floodlight body, making it not only thin and light after assembly but also providing basic waterproofing. It is lightweight, portable, easy to assemble and disassemble, and angle adjustable. This is mainly reflected in simplifying the solar floodlight into two parts: a solar panel with a battery and a lampshade with a light panel. The lampshade is integrally molded with multiple independent lenses. Furthermore, the light panel is directly integrated with the lampshade, eliminating the need for an external lamp housing as in traditional designs. The bottom layer of the light panel is a flat, heat-conducting substrate, with a heat-conducting insulating layer on top, followed by a conductive layer and an LED substrate. Therefore, the direct assembly of the light panel with the lampshade, along with the sealing ring and waterproof adhesive, provides a certain degree of waterproofing, sealing, heat dissipation, and protection. This reduces the need for a lamp housing and its weight while ensuring normal outdoor operation. This utility model not only saves costs, processes, and assembly steps but also achieves the research and development goal of structural optimization. Attached Figure Description

[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] like Figures 1 to 3 As shown, this utility model is a simple and reasonable waterproof floodlight body structure, which mainly consists of a solar panel shell 1 and a lampshade 2.
[0016] The solar panel housing 1 is designed with a receiving cavity 10 and a first auxiliary support arm 11. The receiving cavity 10 is for positioning and limiting the installation of the battery. Therefore, the receiving cavity 10 also has a wire outlet hole 12 to lead out the power cord. Of course, the wire outlet hole 12 needs to be used with a waterproof plug to maximize practicality and waterproof effect. The first auxiliary support arm 11 is matched with the second auxiliary support arm 25 designed on the lamp cover 2 for mutual assembly. The two can not only be connected by a connector, but also have their relative angles adjusted to adjust the angle at which the solar panel receives sunlight or the emission angle after the lamp panel is installed. This design ensures the flexibility and practicality of this utility model as a floodlight.
[0017] The back of the solar panel housing 1 is integrally formed with multiple heat dissipation protrusions 13, while the front is designed as a recessed plane 14. The design of the heat dissipation protrusions 13 can increase heat dissipation performance.
[0018] Compared to the design of some outdoor lights with a housing, this invention not only saves costs, processes, and assembly steps, but also achieves the research and development goal of structural optimization. This is mainly reflected in the simplification of the solar floodlight into two parts: a solar panel with a battery and a lampshade 2 with a light panel. The front of the solar panel housing 1 has a recessed flat surface 14 to accommodate the solar panel, while the lampshade 2 is integrally formed with multiple independent lenses 20. Furthermore, the light panel is directly integrated with the lampshade 2, thus differentiating this invention from traditional designs and achieving a thinner profile. While traditional lights have an external housing, the bottom layer of the light panel is a flat, heat-conducting substrate, with a heat-conducting insulating layer on top, followed by a conductive layer and an LED substrate. Therefore, the light panel can be directly fitted to the lampshade 2. Simultaneously, this invention incorporates a sealing ring and waterproof adhesive, providing waterproofing, sealing, heat dissipation, and protection, reducing the need for a housing while ensuring normal outdoor operation.
[0019] Regarding the lampshade 2, it is worth noting that its inner surface is integrally molded with multiple independent lenses 20 as needed, and the edge of the inner surface is also surrounded by a mounting groove 21 for fixing and embedding a sealing ring and a protective groove 22 for filling with waterproof adhesive. The number and position of the lenses 20 are determined according to the LED beads on the lamp board to achieve better light emission from the LED beads. More importantly, this is part of optimizing the lamp body structure, ensuring the lighting effect while reducing the need for additional lens assembly and corresponding structural designs. All of this can be integrally molded onto the lampshade 2 based on existing technology. The mounting groove 21 and the protective groove 22 are two layers of waterproof structure designed around the lamp board in this invention. Since this invention is an outdoor lamp that needs to be effectively waterproof, this design achieves the research and development objective, extends the service life, improves safety, and does not negatively impact the optimized structure. Furthermore, the lampshade 2 is molded with a cavity 23, which is designed to reserve assembly space for components and other modules on the lamp board, preventing them from colliding with the lampshade due to insufficient space.
[0020] During assembly, the mounting groove 21 and protective groove 22 of the lampshade 2 are pre-fitted with sealing rings and waterproof adhesive. Then, the lamp panel is fixed to the inside of the lampshade 2 using screws and auxiliary guide posts 24. At this point, the lamp panel is secured by both the screws and the waterproof adhesive. The lampshade 2 is then assembled with the solar panel housing 1 containing the battery via connectors. Finally, the battery is electrically connected to the lamp panel. This invention features a reasonable and simple structure, is waterproof, lightweight, and provides guaranteed light output.
