Description

Technical Field

[0001] The invention relates to the technical field of outdoor lighting, and in particular to a rainproof box suitable for outdoor lighting projects. Background Art

[0002] Based on the requirements of the "Architectural Lighting Design Standard" (GB / T 50034-2024), outdoor lighting projects must be used in conjunction with independent isolated drive power supplies when LEDs are used as lighting sources, and DC overload and short-circuit protection devices should be installed at the beginning of each DC distribution circuit as overcurrent protection measures. This improvement not only improves the level of installation technology, but also puts higher requirements on the layout of the drive power supply.

[0003] In the past lighting projects, the early stages of the project often resulted in the driver power supply being arranged along with the lights due to poor planning of the power distribution route. Rainproof boxes or waterproof power supplies were often used as outdoor rainproof solutions. Although this approach simplified the installation process, it increased the cost burden invisibly. What’s more serious is that when the driver power supply has dual outputs, it is difficult to meet the requirements of the new specifications. In addition, although this decentralized layout shows installation flexibility, it also brings a heavy burden to subsequent maintenance and management. Summary of the invention

[0004] In view of this, an embodiment of the present invention provides a rainproof box suitable for outdoor lighting projects to solve the technical problems that commonly used rainproof boxes or waterproof power supplies are difficult to meet the requirements of new specifications, are costly, and are inconvenient to maintain and manage.

[0005] An embodiment of the present invention provides a rainproof box suitable for outdoor lighting projects, comprising a waterproof cabinet, the front of which is provided with inner and outer double-layer protective doors, and a mounting frame is provided inside the waterproof cabinet;

[0006] The mounting frame is provided with a plurality of LED driving power supplies and a DC circuit breaker and a wiring terminal matching the output current of the LED driving power supplies;

[0007] Alternatively, a plurality of LED controllers are mounted on the mounting frame.

[0008] Optionally, a wire trough is provided in the middle of the mounting frame, the LED driving power supply is arranged above the wire trough, and the DC circuit breaker and the wiring terminals are arranged side by side below the wire trough.

[0009] Optionally, the number of the LED driving power supplies does not exceed 3.

[0010] Optionally, a rainproof cap is provided on the top of the waterproof cabinet.

[0011] Optionally, the waterproof cabinet is made of stainless steel, and the dimensions of the waterproof cabinet are 500 mm in height, 400 mm in length, and 200 mm in width.

[0012] Optionally, the number of the LED controllers does not exceed 2.

[0013] Optionally, a fixing frame is installed on the back of the waterproof cabinet, and the fixing frame is welded and fixed to the steel frame body of the building.

[0014] Optionally, the waterproof cabinet is fixed to a solid wall of a building by means of expansion bolts.

[0015] The embodiments of the present invention have the following beneficial effects: a larger waterproof cabinet is used to replace scattered rainproof boxes or waterproof power supplies, scientifically grouped LED drive power supplies and wiring terminals are arranged in the waterproof cabinet, and a DC circuit breaker is embedded in the waterproof cabinet for protection, which can not only fully meet all regulatory requirements, but also effectively control costs and facilitate subsequent maintenance and management; similarly, LED controllers used in outdoor lighting projects can also be grouped and placed in a waterproof cabinet for rainproof installation.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0024] See also Figure 1 As shown, the embodiment of the present invention provides a rainproof box suitable for outdoor lighting projects, including a waterproof cabinet 1, the front of the waterproof cabinet 1 is equipped with an inner and outer double-layer protective door 2 (protection level IP55), and the top of the waterproof cabinet 1 is provided with a rainproof cap 3 to prevent the waterproof cabinet 1 from being exposed to the sun and rain. Specifically, the waterproof cabinet 1 in the embodiment of the present invention can be a stainless steel cabinet with a size of 500mm (height) x 400mm (length) x 200mm (width).

[0025] A mounting frame 4 is provided in the waterproof cabinet 1, and a plurality of LED driving power supplies 5 and a DC circuit breaker 6 and a wiring terminal 7 matching the output current of the LED driving power supply 5 are installed on the mounting frame 4. The number of LED driving power supplies 5 and the corresponding DC circuit breakers 6 and wiring terminals 7 in each waterproof cabinet 1 can be reasonably allocated according to the specific power distribution conditions of the lighting project, but the number of LED driving power supplies 5 is preferably not more than 3 to avoid complicated wiring in the cabinet.
