[0035] The street lamp structure of the application separates the light source module 200 and the power module, and realizes the electrical connection of the two through the detachable electric connection, which not only simplifies the installation and disassembly process, reduces the maintenance cost, but also improves the reliability and flexibility of the street lamp.

[0036] According to some embodiments of the application, in order to enhance the heat dissipation effect, the inner wall or outer wall of the first cavity 110 can be designed with heat dissipation fins, heat dissipation grooves or heat dissipation holes, which can increase the contact area with air and promote the convection and radiation heat dissipation of heat.

[0037] Specifically, the inner wall of the first cavity 110 of the lamp shell 100 of the application is provided with heat dissipation fins.

[0038] According to some embodiments of the application, the external power supply shell includes a first shell 320 and a second shell, the second cavity 321 is arranged on the first shell 320, and the second shell is connected to the opening of the second cavity 321, and the second electric connection 310 is fixed on the second shell.

[0039] Further, the second shell is provided with a third cavity 332, and the second electrical connecting member 310 is installed in the third cavity 332, and the second electrical connecting end extends to the outside of the third cavity 332. The first ring plate 311 is arranged at one end of the second electrical connecting end towards the lamp shell 100, and the first ring plate 311 is matched and inserted with the first connecting hole. Wherein, the first ring plate 311 can play a guiding and positioning role when the power module is connected with the lamp shell 100.

[0040] Specifically, the second shell includes an upper cover 330, a middle cover 340 and a lower cover 350 connected in sequence in the vertical direction, the middle cover 340 and the lower cover 350 are both provided with coaxial through holes, the second shell 330 is provided with a second ring plate 331 on the side close to the middle cover 340, the inner wall of the second ring plate 331 forms a third cavity 332, one end of the second electrical connecting member 310 is connected in the third cavity 332, and the other end of the second electrical connecting member 310 is connected to the first connecting hole after sequentially passing through the through holes of the middle cover 340 and the lower cover 350.

[0041] As a further improvement of the scheme, the outer wall of the middle cover 340 is provided with an arc-shaped connecting groove 341, and the inner wall of the upper cover 330 is provided with a wedge-shaped connecting block 333, the wedge-shaped connecting block 333 is connected with the arc-shaped connecting groove 341, and rotating the upper cover 330 can make the wedge-shaped connecting block 333 move along the arc-shaped connecting groove 341, so as to realize the disassembly and assembly of the upper cover 330 and the middle cover 340. Specifically, two arc-shaped connecting grooves 341 are circumferentially arranged on the outer wall of the middle cover 340 around the axis of the middle cover 340. At the same time, correspondingly, the wedge-shaped connecting block 333 is matched with two arc-shaped connecting grooves 341.

[0042] It can be understood that the wedge-shaped connecting block 333 and the arc-shaped connecting groove 341 form a rotating fixing structure. The opening direction of the arc-shaped connecting groove 341 is generally consistent with the rotating direction of the wedge-shaped connecting block 333, so that the wedge-shaped connecting block 333 can smoothly enter and rotate along its track. When the street lamp needs to be assembled, first, the upper cover 330 is aligned with the middle cover 340, and the wedge-shaped connecting block 333 is aligned with the opening of the arc-shaped connecting groove 341. Then, by rotating the upper cover 330, the wedge-shaped connecting block 333 gradually penetrates along the track of the arc-shaped connecting groove 341. Due to the design of the wedge-shaped connecting block 333 that is wide at the top and narrow at the bottom, when it is rotated to a certain angle, the narrower end will be firmly clamped in the arc-shaped connecting groove 341, thereby realizing the fixed connection of the upper cover 330 and the middle cover 340.

[0043] The rotating fixing structure of the wedge-shaped connecting block 333 and the arc-shaped connecting groove 341 makes the assembly and disassembly of the street lamp very simple and fast, without the need to use additional tools or fasteners. Moreover, due to the design of the wedge-shaped connecting block 333 being wide at the top and narrow at the bottom, when rotated to a certain angle, it will be automatically locked in the arc-shaped connecting groove 341 and is not easy to loosen or fall off. The rotating fixing structure of the wedge-shaped connecting block 333 and the arc-shaped connecting groove 341 is not only practical, but also has a certain degree of aesthetics, which can improve the overall appearance of the street lamp.

[0044] According to some embodiments of the present application, the second power connection 310 is a male aviation socket, and the first power connection is a female aviation socket matched therewith. This connection method not only facilitates plugging and unplugging, but also has good electrical performance and waterproof performance, which can meet the requirements of the street lamp structure for connection reliability, waterproof and dustproof performance, and easy maintenance, etc.

[0045] According to some embodiments of the present application, the light source module 200 includes a main substrate 210 and independent light source assemblies arranged on the main substrate 210. The independent light source assemblies are arranged in a matrix. Further, the independent light source assemblies include a sub-substrate 220 and light emitting pieces 230 arranged on the sub-substrate 220. The sub-substrate 220 is fixed on the main substrate 210, and the light emitting pieces 230 are arranged in a matrix. This arrangement not only improves the lighting effect and coverage range of the light source module 200, but also enhances the lighting intensity and uniformity of the street lamp through the superposition effect of multiple light sources. At the same time, the matrix arrangement is also helpful for heat dissipation of the light source module 200, because there is enough space around each light emitting piece 230 for heat dissipation, thereby reducing the overall temperature of the light source module 200.

[0046] According to some embodiments of the present application, the lamp shell 100 is also connected with an angle adjusting mechanism 400. Through the angle adjusting mechanism 400, the user can adjust the inclination angle or rotation direction of the lamp shell 100 (and the light source module 200) without changing the overall installation position of the street lamp. In this way, the lighting range of the street lamp can be more flexibly adapted to different environments and needs, such as illuminating sidewalks, roads, or specific areas.
