Description

Technical Field

[0001] This utility model belongs to the field of solar street light technology, specifically, it relates to a lamp arm type sheet metal solar street light. Background Technology

[0002] Solar streetlights are lighting devices that utilize solar energy as their primary energy source. They convert sunlight into electricity through solar panels, store the electricity, and provide lighting services at night or when sunlight is insufficient. Due to their environmental friendliness, economic efficiency, and sustainability, solar streetlights are being widely used globally.

[0003] Existing solar streetlights are basically composed of a cylindrical lamp post, a die-cast lamp body, and a solar panel. Because the lamp body is made using a die-casting process, the overall weight of the lamp body is relatively large, which is wasteful of materials and makes installation difficult, time-consuming, and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a lamp arm type sheet metal solar street light that is manufactured using sheet metal technology, which greatly reduces the amount of street light material used.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] A sheet metal solar street light with a lamp arm includes a lamp post, a lamp body, and a solar module. The solar module is fixed to the top of the lamp post. The lamp body is fixed to the lamp post and located at the bottom of the solar module via a lamp arm that is fixedly connected to the lamp body. The lamp body includes a lamp housing, a lamp cover, and a light-emitting module placed inside the lamp housing. The lamp arm, the lamp housing, and the lamp cover are all made using sheet metal technology. The rear end of the lamp housing has an installation hole for the front end of the lamp arm to enter. The lamp housing has a locking mechanism that is fixed to the lamp housing. The locking mechanism locks the front end of the lamp arm. The lamp cover completely covers and seals the lamp housing.

[0007] Specifically, the locking mechanism includes a mounting plate welded to the inner wall of the lamp housing, and the front end of the lamp arm is fixed to the mounting plate by bolts.

[0008] Preferably, the mounting plate includes an upper mounting plate and a lower mounting plate, the distance between the upper mounting plate and the lower mounting plate matches the front end of the lamp arm, and the upper mounting plate and the lower mounting plate are distributed vertically and fixed to the front end of the lamp arm by bolts respectively.

[0009] Specifically, it also includes a battery pack, the length of which matches the length of the mounting plate, and the battery pack is placed on the mounting plate and adjacent to the front end of the lamp arm.

[0010] Preferably, the rear end of the lamp arm is provided with a connecting sleeve, which is nested at the top of the lamp post and fixed by bolts.

[0011] Specifically, the solar module includes a solar panel, an angle adjustment mechanism, and a rotating column. The angle adjustment mechanism connects the solar panel and the rotating column, and the bottom of the rotating column is embedded in the connecting sleeve and fixed by bolts.

[0012] Preferably, the lower surface of the front end of the lamp housing is inclined.

[0013] This invention offers the following advantages: By employing sheet metal processing to manufacture the lamp arm and lamp housing, and using a lightweight lamp housing to support the light-emitting module, the material usage for the lamp body and lamp arm is significantly reduced, thereby decreasing the overall weight of the streetlight. Furthermore, the use of mounting plates for the lamp arm, particularly the double-layer mounting plate method, improves the fixing effect. This structure also concentrates and compacts the stress points, allowing most of the lamp body's weight to be directly applied to the lamp arm, reducing stress on other parts of the lamp body and effectively improving the lamp's safety.

[0024] An embodiment of this utility model provides a lamp arm type sheet metal solar street light, such as... Figure 1-4 As shown, the lamp includes a lamp post 1, a lamp body 3, and a solar module 4. The solar module 4 is fixed to the top of the lamp post 1. The lamp body 3 is fixed to the lamp post 1 and located at the bottom of the solar module 4 via a lamp arm 2 fixedly connected to the lamp body 3. The lamp body 3 includes a lamp housing 31, a lamp cover 34, and a light-emitting module 35 placed inside the lamp housing 31. The lamp arm 2, the lamp housing 31, and the lamp cover 34 are all made using sheet metal technology. The rear end of the lamp housing 31 has an installation hole for the front end of the lamp arm 2 to enter. The lamp housing 31 has a locking mechanism that is fixed to the lamp housing 31. The locking mechanism locks the front end of the lamp arm 2. The lamp cover 34 completely covers and seals the lamp housing 31. The lamp arm 2, the lamp housing 31, and the lamp cover 34 are all made using sheet metal technology, resulting in a stable and lightweight structure after molding, which greatly reduces the amount of material used in the street light and greatly facilitates the production, installation, and transportation of the street light.

[0025] Specifically, the locking mechanism includes a mounting plate welded to the inner wall of the lamp housing 31, and the front end of the lamp arm 2 is fixed to the mounting plate with bolts. The mounting plate connects the lamp arm 2 to the lamp housing 31, so that the weight of the lamp housing 31 is mainly borne by the lamp arm 2. Specifically, it also includes a battery pack 36, the length of which matches the length of the mounting plate. The battery pack 36 is placed on the mounting plate and adjacent to the front end of the lamp arm 2. That is, the weight of the battery is also borne by the lamp arm 2, thus concentrating and compacting the support points, and ensuring that the main weight of the lamp body 3 is completely supported by the lamp arm 2, effectively improving the service life of the lamp body 3.

[0026] Preferably, the mounting plate includes an upper mounting plate 32 and a lower mounting plate 33. The distance between the upper mounting plate 32 and the lower mounting plate 33 matches the front end of the lamp arm 2. The upper mounting plate 32 and the lower mounting plate 33 are distributed vertically and are respectively fixed to the front end of the lamp arm 2 by bolts. Using the upper and lower mounting plates 33 makes the connection between the lamp housing 31 and the lamp arm 2 more stable and fixed, while ensuring the stability of the lamp body 3 in use.

[0027] Preferably, the rear end of the lamp arm 2 is provided with a connecting sleeve 21, which is nested in the top of the lamp post 1 and fixed with bolts. Specifically, the solar module 4 includes a solar panel, an angle adjustment mechanism, and a rotating column. The angle adjustment mechanism connects the solar panel and the rotating column, and the bottom of the rotating column is embedded in the connecting sleeve 21 and fixed with bolts. The connecting sleeve 21 connects the lamp post 1, the solar module 4, and the lamp arm 2, ensuring the stability of the three components. The presence of the connecting sleeve 21 also ensures the horizontal adjustment capability of the solar module 4.

[0028] Preferably, the lower surface of the front end of the lamp housing 31 is inclined. By tilting the lamp housing 31, the light source of the light-emitting module 35 is designed with an inclined angle, which can provide a better lighting angle and does not require later adjustment. Only an additional sheet metal process is needed during the manufacturing of the lamp housing 31 to set the inclined bottom surface, which is convenient and labor-saving.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
