Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a waterproof structure for an LED lamp. Background Art

[0002] LED lamps used outdoors are often exposed to various harsh weather conditions, especially rain erosion. If rainwater enters the interior of the lamp, it may cause problems such as circuit short circuit and light source damage, which seriously affect the service life and performance of the lamp. Although the existing waterproof structures for LED lamps can prevent rainwater from entering to a certain extent, there are still some deficiencies. For example, the waterproof effect at the connection between the mounting plate and the housing of some lamps is poor, and rainwater is easy to seep through these gaps; at the same time, the waterproof design around the transparent plate is not perfect, and rainwater may accumulate around the transparent plate and gradually seep into the interior of the lamp; in addition, some lamps ignore the heat dissipation problem in the waterproof design, resulting in the performance of the lamp being affected due to poor heat dissipation during long-term use. Therefore, a more effective waterproof structure for LED lamps is needed to solve these problems. Contents of the Utility Model

[0003] The utility model provides a waterproof structure for an LED lamp, which solves the problems in the background art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions: A waterproof structure for an LED lamp includes an LED light source disposed inside a housing, a rotatable bracket with a "U"-shaped cross section is arranged on the surface of the housing, a mounting plate connected by bolts is arranged in front of the housing, and a transparent plate is mounted on the inner wall of the mounting plate; The surface of the mounting plate is connected with a protective plate having an inverted "U"-shaped cross section through bolts, and the inner wall of the protective plate is connected with a guide plate connected to the inner wall of the mounting plate; The inner wall of the guide plate is arranged in an inclined manner.

[0005] Preferably, the protective plate wraps and shields the top end and the left and right sides of the connection part between the housing and the mounting plate.

[0006] Preferably, the guide plate and the inner wall of the mounting plate are connected by waterproof adhesive.

[0007] Preferably, the front side of the housing is connected with a positioning plate through bolts, a protective plate with a square-shaped cross section is integrally formed on the rear side of the positioning plate, the inner wall of the positioning plate is provided with a mounting groove connected with the transparent plate through waterproof adhesive, and heat dissipation fins are respectively arranged on the four peripheral sides of the inner wall of the protective plate.

[0008] Preferably, the heat dissipation fins are arranged in a staggered manner on the inner wall of the protective plate.

[0009] Preferably, the inner wall of the mounting groove is inclined around its perimeter, and the minimum cross-sectional area inside the mounting groove is the same as the cross-sectional area of ​​the transparent plate.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, a protective plate shields the connection between the mounting plate and the housing, effectively preventing rainwater from entering the housing through this connection and improving the lamp's waterproof capability. Simultaneously, a guide plate directs rainwater onto the transparent plate, preventing rainwater accumulation around the transparent plate and further ensuring a dry environment inside the lamp.

[0011] In this invention, a positioning plate and a mounting groove are used to install the transparent plate. The inclined design of the inner wall of the positioning plate facilitates the drainage of rainwater, reducing the time rainwater stays around the transparent plate. Moreover, the positioning plate and the protective plate are integrally molded, which can shield the connection between the positioning plate and the shell, effectively preventing rainwater from entering from these parts and enhancing the overall waterproof effect.

[0012] In this invention, heat dissipation fins are provided around the inner wall of the protective plate, which can effectively solve the heat dissipation problem of the lamp while ensuring waterproof performance. The staggered arrangement of the heat dissipation fins increases the heat dissipation area and improves the heat dissipation efficiency, ensuring that the LED light source works at a suitable temperature, extending the service life of the lamp, and to a certain extent preventing rainwater from entering the interior of the housing through the gap between the protective plate and the housing.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Reference Figures 1-3 A waterproof structure for an LED lamp includes an LED light source housed inside a housing 1. A rotatable bracket 2 with a U-shaped cross-section is mounted on the surface of the housing 1. A mounting plate 3, bolted to the front of the housing 1, has a transparent plate 4 mounted on its inner wall. A protective plate 5 with an inverted U-shaped cross-section is bolted to the surface of the mounting plate 3, and a guide plate 6 connected to the inner wall of the mounting plate 3 is attached to the inner wall of the protective plate 5. The guide plate 6 has an inclined inner wall, and the inverted U-shaped cross-section of the protective plate 5 wraps and shields the top and sides of the connection between the housing 1 and the mounting plate 3, structurally blocking the intrusion path of rainwater. The inclined inner wall of the guide plate 6 is connected to the inner wall of the mounting plate 3 with waterproof adhesive. When rainwater falls onto the transparent plate 4, the inclined structure of the guide plate 6 guides the rainwater to flow down quickly, preventing rainwater accumulation on the transparent plate 4 and the mounting area, effectively preventing rainwater from seeping into the housing 1.

[0017] Furthermore, the protective plate 5 covers and shields the top and left and right sides of the connection between the housing 1 and the mounting plate 3, in order to prevent rainwater from entering the interior of the housing 1 through the top and left and right sides of the connection between the housing 1 and the protective plate 5.

[0018] Furthermore, the guide plate 6 and the inner wall of the mounting plate 3 are connected by waterproof adhesive to prevent rainwater from falling into the gap between the guide plate 6 and the mounting plate 3.

[0019] Example 2 The difference from Example 1 is as follows: See Figure 4 , Figure 5The positioning plate 7 is bolted to the front of the housing 1. The mounting groove 9 on its inner wall is connected to the transparent plate 4 with waterproof adhesive, achieving a stable installation of the transparent plate 4. The inner wall of the mounting groove 9 is inclined around its perimeter, and the minimum cross-sectional area inside is the same as the cross-sectional area of ​​the transparent plate 4. This design not only facilitates the installation of the transparent plate 4, but also allows rainwater to flow out smoothly, reducing the amount of rainwater remaining in the mounting groove 9. The positioning plate 7 and the protective plate 8 are integrally formed. The protective plate 8 can cover the connection between the positioning plate 7 and the housing 1, preventing rainwater from entering the lamp through these connection points, further improving the waterproof performance. At the same time, the heat dissipation fins 10 on the inner wall of the protective plate 8 provide good heat dissipation conditions for the lamp, ensuring the normal operation of the lamp.

[0020] Furthermore, the heat dissipation fins 10 are staggered on the inner wall of the protective plate 8. The heat dissipation fins 10 can effectively solve the heat dissipation problem of the lamp while ensuring waterproof performance. The staggered arrangement of the heat dissipation fins 10 increases the heat dissipation area, improves the heat dissipation efficiency, ensures that the LED light source works at a suitable temperature, and extends the service life of the lamp.

[0021] Furthermore, the inner wall of the mounting groove 9 is inclined around its perimeter, and the minimum cross-sectional area of ​​the mounting groove 9 is the same as the cross-sectional area of ​​the transparent plate 4. The inclined inner wall of the mounting groove 9 facilitates the drainage of rainwater falling on the transparent plate 4. The fact that the minimum cross-sectional area of ​​the mounting groove 9 is the same as the cross-sectional area of ​​the transparent plate 4 prevents large gaps at the connection between the transparent plate 4 and the mounting groove 9, which would cause rainwater to accumulate there and prevent it from seeping into the interior of the housing 1 over a long period of time.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
