[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-4 , the utility model provides the following technical solutions:

[0030] Low-power and high-efficiency street lamp driver power pack, including:

[0031] Shell 1;

[0032] The cover plate 2 is threadably connected to the upper end of the housing 1 by bolts;

[0033] A connecting seat 3, the connecting seat 3 is fixedly connected to the lower end of the shell 1;

[0034] The frame 6 is connected to the connection seat 3 , a notch 7 is provided on the frame 6 , a power supply group 8 is connected to the frame 6 , a protrusion 9 is fixedly connected to the side end of the power supply group 8 , and the protrusion 9 matches the notch 7 .

[0035] In a specific embodiment of the utility model, the housing 1 provides a protective physical barrier for the power pack 8, which can prevent the external environment such as moisture, dust, chemicals, etc. from damaging the internal electronic components. This helps to improve the life and stability of the power pack 8. The cover 2 is used to close the housing, further protect the internal power pack 8 from the external environment, and provide a heat dissipation platform for the power pack 8. Heat dissipation is a key factor in improving the efficiency and life of the power pack 8, because poor heat dissipation will cause the internal temperature to rise, affecting the performance of electronic components. The connection seat 3 is used to fix and connect the power pack 8 stably to ensure the stability and safety of the electrical connection. The frame 6 is used to support and fix the power pack 8 to keep its position stable. At the same time, the notch 7 and the protrusion 9 on the frame 6 are designed to match each other, which can further fix the power pack 8 and improve its stability. The power pack 8 is the core of the entire LED street light system, responsible for converting AC power into DC power suitable for LED lamp beads, while performing power factor correction and current control. An efficient power pack 8 can improve the energy utilization of the entire system, reduce energy consumption and heat generation. These components together form a low-power and high-efficiency LED street light driver power pack, which can not only improve the performance and stability of the street light system, but also reduce energy consumption, extend service life and reduce maintenance costs.

[0036] For details, please refer to Figure 2 and Figure 3 A frame plate 10 is connected to the frame 6 , and a heat dissipation fin 11 is connected to the upper end of the frame plate 10 .

[0037] In this embodiment: the frame plate 10 is a planar structure used to further fix and support the electronic components inside the power pack 8. It helps to maintain the shape and stability of the power pack 8, while providing a certain space for internal heat dissipation. The heat sink fins 11 are common heat dissipation elements, which improve the heat dissipation efficiency by increasing the surface area. In this embodiment, the heat sink fins 11 are connected to the upper end of the frame plate 10, which can effectively conduct the heat generated inside the power pack 8 to the external environment, thereby keeping the temperature of the power pack 8 within a reasonable range and improving its working efficiency and life. In this way, the heat sink fins 11 can enhance the heat dissipation capacity of the power pack 8, help reduce the internal temperature, and thus improve the efficiency and reliability of the power pack 8. This is crucial to ensure the long-term stable operation of the LED street light system.

[0038] For details, please refer to Figure 3 The frame 6 , the frame plate 10 , the threaded bolt 12 and the connecting seat 3 are threadedly connected with the threaded bolt 12 .

[0039] In the present embodiment, the threaded bolt 12 is a threaded bolt for connecting parts, which cooperates with a nut or a preset threaded hole through its thread to provide a secure connection mode. In this embodiment, the threaded bolt is used to connect the frame 6, the frame plate 10 and the connecting seat 3, ensuring the stability and durability of the connection.

[0040] For details, please refer to Figure 3 A vent 4 is provided at the lower end of the shell 1.

[0041] In this embodiment, the design of the vent 4 allows air to circulate, which helps to dissipate heat. Through the vent 4, external air can enter the housing 1 to help dissipate heat, while taking the internal heat out to keep the operating temperature of the power pack 8 within a suitable range.

[0042] For details, please refer to Figure 1 A heat dissipation port 13 is provided at the upper end of the cover plate 2 .

[0043] In this embodiment: the heat dissipation vents 13 provide an additional path so that heat can be dissipated from the inside of the power pack 8 to the external environment more efficiently. This helps to reduce the internal temperature of the power pack, thereby improving its operating efficiency and life. Through the heat dissipation vents 13, air can circulate, promoting heat convection, which means that hot air rises and cold air falls, forming a natural cycle that helps to evenly distribute heat.

[0044] For details, please refer to Figure 1-3 A connector 5 is provided in the housing 1 .

[0045] In this embodiment: the connector 5 is a device for electrical connection, which allows connection points between different circuit components and ensures that the electrical connection between the power pack 8 and other system components such as LED lamp beads, control system, etc. is stable and reliable.

[0046] It should be noted that the specific type of connector 5, power pack 8 and heat sink fins 11 to be used is selected by relevant technical personnel familiar with the field, and the above connector 5, power pack 8 and heat sink fins 11 are all existing technologies and will not be elaborated in this solution.

[0047] The working principle and use process of the utility model: First, assemble the shell 1 and the cover plate 2 together and connect them by bolts. Make sure that the frame 6 is connected to the connecting seat 3 and the power pack 8 is installed in the frame 6. The protrusion 9 should match the recess 7 to ensure the correct installation of the structure. Use the threaded bolt 12 to thread the frame 6, the frame plate 10 and the connecting seat 3 to ensure a stable connection. The air vent 4 at the lower end of the shell 1 and the heat dissipation port 13 at the upper end of the cover plate 2 are designed to dissipate heat to keep the operating temperature of the power pack within an appropriate range. A connector 5 is provided in the shell 1 to connect the output end of the power pack 8 to the LED lamp beads or other electrical equipment. After completing all the assembly and connection steps, the power pack can be started to convert the electrical energy into current and voltage suitable for the LED lamp beads. Check the operating status of the power pack regularly to ensure the normal operation of the connector 5 and other components.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
