Description

Technical Field

[0001] The utility model relates to the field of street lamps, in particular to a module assembled street lamp. Background Art

[0002] Most urban roads and rural roads in residential areas are equipped with street lamps. The upper shell and the bottom shell of the existing street lamp housing are both one-piece molding designs. When installing, the upper shell is snapped onto the bottom shell, and the street lamp LED module of this structure is installed in the bottom shell. However, the lamp shell of this street lamp is large in size, which requires high production resource investment. In addition, the LED module of this street lamp has special requirements for road lighting brightness or cannot respond flexibly when it changes. The entire lamp head needs to be replaced, which will increase the purchase and installation costs of the replacement lamp head. At the same time, it is difficult to find a suitable application site for the replaced lamp head, resulting in a waste of resources. Utility Model Content

[0006] The LED module includes a radiator, a lamp board, a lens and a cover plate. Through holes are processed on both sides of the radiator, and positioning screws are provided on the radiator perpendicular to the through holes. The lamp board is installed at the bottom of the radiator, a waterproof strip is processed in the middle of the radiator, and the cover plate is installed on the waterproof strip.

[0007] The modular assembled street lamp provided by the utility model has the following beneficial effects:

[0008] (1) By providing a support arm and installing LED modules on the support arm, the number of LED modules can be increased or decreased according to the demand for high / low road lighting brightness during use, without having to replace the entire lamp head, effectively reducing the material and production costs of the product, thereby reducing resource waste;

[0009] (2) The LED module integrates a heat sink, and the heat sink and the lamp holder shell form a whole, moving the traditional lamp holder to the outside, thereby ensuring the heat dissipation effect and effectively increasing the service life of the product;

[0010] (3) Easy to replace and repair, effectively reducing subsequent maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example

[0018] like Figure 1 to Figure 4As shown, the module-assembled street lamp provided in this embodiment includes a lamp pole bracket 1, a rear end upper cover 2, a rear end lower cover 3, an LED module 5 and a front end cover 4, wherein the rear end lower cover 3 is connected to the lamp pole bracket 1, and a parallel support arm 31 is installed at one end of the rear end lower cover 3 away from the lamp pole bracket 1, and the cross-section of the support arm 31 is square, and the front end cover 4 is connected to the end of the support arm 31 away from the rear end lower cover 3, and locking screws matching the support arm 31 are installed on the side walls on both sides of the front end cover 4, and through holes for the support arm 31 to pass through are processed on both sides of the LED module 5, and at least one group of LED modules 5 is mounted on the support arm 31 between the front end cover 4 and the rear end lower cover 3. The number of LED modules 5 can be increased according to lighting needs, and multiple groups of LED modules 5 can improve the brightness of lighting. The rear end upper cover 2 is installed above the rear end lower cover 3. For the convenience of maintenance, the LED module 5 includes a radiator 51, a lamp board 52, a lens and a cover plate 53, through holes are processed on both sides of the radiator 51, and positioning screws are provided on the radiator 51 perpendicular to the through holes, and the position of the radiator 51 on the support arm 31 can be locked by the positioning screws. The lamp board 52 is installed at the bottom of the radiator 51, and a waterproof strip is processed in the middle of the radiator 51. The power cord interface of the lamp board 52 is between the waterproof strips. The cover plate 53 is installed on the waterproof strip. The power cord interface on the radiator 51 can be blocked by the cover plate 53, thereby ensuring the working state of the LED module 5. The openings at both ends of the radiator 51 are closed by the rear end upper cover 2 and the rear end lower cover 3, as well as the front end cover 4. This structure is used to move the radiator 51 traditionally installed in the lamp holder to the outside, thereby improving the heat dissipation effect, thereby effectively extending the service life of the LED module 5. At the same time, the external placement of the radiator 51 effectively reduces the volume of the street lamp, thereby reducing the material used in the product and reducing the waste of resources.

[0019] The method of using the utility model is:

[0020] During maintenance, the front cover 4 is removed to expose the support arm 31, and then the positioning screws are loosened to remove the LED module 5. After replacing the new LED module 5, the front cover 4 is reinstalled to complete the maintenance of the street lamp.

[0021] When adjusting the brightness, remove the rear end upper cover 2, replace the support arm 31 of corresponding length according to the number of LED modules 5, then install the LED module 5 on the replaced support arm 31, then install the front end cover 4 on the support arm 31, and finally cover the rear end upper cover 2 to complete the brightness adjustment.

[0022] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
