[0002] LED streetlights are road lighting fixtures that use LEDs (light-emitting diodes) as light-emitting devices. They have significant advantages such as energy saving, environmental protection, and long lifespan. Compared with traditional lighting equipment such as high-pressure sodium lamps, LED streetlights can provide superior light quality and higher operational reliability. Their light directionality is also more precise, which helps control glare and reduce light pollution.

[0003] However, existing LED streetlights typically consist of a lamp housing, an LED light source, and a driver. The LED light source is bolted to the lamp housing, which is divided into an upper and lower housing. The driver and other components are housed within the cavity formed by these two housings. Currently, bolts are commonly used to connect and secure the upper and lower housings, as well as the driver and other components. This structure means that during maintenance and repair, operators often need to disassemble the entire light and then loosen the bolts connecting the upper and lower housings one by one to inspect or replace internal components such as the driver. Therefore, this process is cumbersome, time-consuming, labor-intensive, costly, and complex. Utility Model Content

[0022] This utility model proposes an easy-to-maintain LED street light.

[0023] like Figures 1 to 6As shown in Embodiment 1 of this utility model, the easy-to-maintain LED street light includes an upper housing 1, a lower housing 2, an LED light source 3, and a driver 4. Specifically, the LED light source 3 is bolted to the outer end of the upper housing 1, and the upper housing 1 serves to accommodate, install, and protect the LED light source 3. An installation handle 25 is provided at the inner end of the lower housing 2, allowing the easy-to-maintain LED street light to be installed as a whole. Further, the lower housing 2 is located at the inner end of the upper housing 1, and a hinge structure is provided on one side between the upper housing 1 and the lower housing 2. A locking structure is provided on the opposite side of the hinge structure, with the hinge structure and locking structure respectively connecting the opposite sides of the upper housing 1 and the lower housing 2.

[0024] Additionally, an annular upper partition 11 is provided on the inner side of the upper housing 1, and an annular lower partition 21 is provided on the inner side of the lower housing 2. A mounting groove is provided at the bottom of the upper partition 11, and a softer mounting ring 15 is provided within the mounting groove. A mating groove is provided at the bottom of the mounting ring 15, and the lower partition 21 is inserted into the mating groove. The driver 4 and other components are then housed inside the annular upper partition 11 and lower partition 21. In this embodiment, the upper partition 11 and lower partition 21, together with the upper housing 1 and lower housing 2, form an independent, enclosed mounting space for installing the driver 4 components, thus isolating the driver 4 and other components from the heat sink area where the LED light source 3 is located. The mounting ring 15 is provided to improve the sealing performance after the upper partition 11 and lower partition 21 are connected, and to increase buffering and stress compensation effects. In other embodiments, the mounting ring 15 may not be provided within the mounting groove of the upper partition 11.

[0025] It is worth noting that the width of the mounting groove is 2 to 3 times the width of the lower partition 21, and the vertical cross-section of the mating groove is trumpet-shaped. When maintaining the LED street light, this design facilitates the smooth alignment of the upper partition 11 (mounting ring 15) and the lower partition 21, so that the two can be accurately mated to perform their functions.

[0026] This utility model connects the upper housing 1 and the lower housing 2 on opposite sides through a hinge structure and a locking structure, allowing the upper housing 1 and the lower housing 2 to rotate and open around the hinge axis 6 of the hinge structure. This facilitates maintenance of internal components such as the drive unit 4 by the staff. Before or after maintenance, the upper housing 1 and the lower housing 2 can be opened or closed by opening or closing the locking structure, eliminating the need to unscrew the bolts connecting the upper and lower housing 2 one by one. This makes the operation more convenient, reduces time and manpower consumption, and lowers maintenance costs and operational complexity.

[0027] like Figure 2 , 3As shown in Figures 4 and 6, the hinge structure includes an upper hinge seat 12, a pressure plate 13, a hinge shaft 6, and a lower hinge seat 22. The upper hinge seat 12 and the lower hinge seat 22 are connected by the hinge shaft 6 after being inserted into each other. Specifically, both the upper hinge seat 12 and the pressure plate 13 have corresponding grooves, which together form an upper hinge hole for installing the pin. The lower hinge seat 22 has a lower hinge hole 221, the width of which is 1.5 to 3 times the diameter of the hinge shaft 6. This design allows the hinge shaft to slide back and forth a small distance within the lower hinge hole 221, thus providing the necessary "movement margin" for the upper housing 1 and the lower housing 2. When the locking structure is locked or unlocked, the upper housing 1 needs to have a slight back and forth displacement relative to the lower housing 2. This sliding space is precisely to accommodate this action and prevent hard interference between the two structures, which could lead to failure to lock or damage. It is worth noting that the lower hinge seat 22 has two connecting plates, both of which are provided with lower hinge holes 221. The upper hinge seat 12 and the pressure plate 13 extend between the two connecting plates and are connected by the hinge shaft 6.

[0028] like Figure 2 , 3 As shown in Figures 4 and 5, the locking structure includes a slot 14, a locking piece 5, and a locking groove. The locking piece 5 is connected to the slot 14, and a locking bar 52 is hinged to the side of the locking piece 5 facing the lower housing 2. The locking bar 52 is detachably inserted into the locking groove. Specifically, an insert block 51 is provided at the upper end of the locking piece 5. The insert block 51 is inserted into the slot 14, forming a receiving space between the insert block 51 and the locking piece 5. The edge of the upper housing 1 extends into the receiving space to improve the stability of the connection between the locking piece 5 and the upper housing 1.

[0029] Furthermore, a circular boss 23 and a protrusion 24 are provided on the outer side of the lower housing 2, forming a slot 14 between the circular boss 23 and the protrusion 24. The aforementioned locking bar 52 is U-shaped, and the bottom two ends of the U-shaped locking bar 52 are rotatably installed on the lower part of the locking plate 5, while the upper horizontal section of the U-shaped locking bar is inserted into the locking groove. The locking bar 52 is installed by a torsion spring. When the locking bar 52 is inserted into the locking groove, it tends to rotate deeper into the locking groove under the action of the torsion spring. When the locking bar 52 of the locking plate 5 is inserted into the locking groove, the circular boss 23 is located in the hollow part of the U-shaped locking bar 52.

[0030] When maintenance is required on components such as the drive unit 4, pressing the locking plate 5 unlocks the mechanism, allowing the upper housing 1 and lower housing 2 to be opened around the hinge shaft 6 for maintenance. After maintenance, the upper housing 1 and lower housing 2 can be closed around the hinge shaft 6, and pressing the locking plate 5 again inserts the locking bar 52 into the locking groove for locking. Therefore, the technical solution of this invention eliminates the need to unscrew the bolts connecting the upper and lower housings 2 one by one, making operation more convenient, reducing time and manpower consumption, and lowering maintenance costs and complexity. In other embodiments, the side of the round boss 23 closest to the protrusion 24 is a vertical surface, and the side away from the protrusion 24 is an inclined surface. This design facilitates the round boss 23 to clamp the locking bar 52 through the vertical surface and facilitates the locking bar 52 to slide upwards through the inclined surface into the locking groove between the vertical surface and the protrusion 24.

[0031] In this embodiment, a buckle plate 53 is provided at the bottom of the lock plate 5. The buckle plate 53 and the outer side of the lower housing 2 form an unlocking port. After the worker presses the lock plate 5 to make the lock bar 52 disengage from the lock groove, the lock plate 5 can be opened through the unlocking port, thereby further opening the upper housing 1 and the lower housing 2, which is simple and convenient.

[0032] It is worth noting that the width of the aforementioned slot 14 is 1.5 to 3 times the width of the insert 51. This design facilitates the sliding of the insert 51 within the slot 14, thereby enabling the locking plate 5 to perform locking and unlocking actions.

[0033] Specifically, the working principle and process of this utility model are as follows: After the upper housing 1 and the lower housing 2 are closed, the operator can lock them using the locking plate 5. Specifically, the operator makes the locking plate 5 cover the round boss 23 and the protrusion 24 of the lower housing 2. At this time, the upper horizontal section of the Z-shaped locking bar 52 is inserted into the slot 14 between the round boss 23 and the protrusion 24 after rotation. The round boss 23 extends into the hollow part of the Z-shaped locking bar 52 to limit the locking bar 52, thereby achieving the locking function.

[0034] When it is necessary to open the upper housing 1 and the lower housing 2, the relative position of the lock bar 52 and the round boss 23 is changed by pressing the lock plate 5, so that the limiting effect of the round boss 23 on the lock bar 52 disappears, thereby allowing the lock bar 52 to smoothly disengage from the lock groove and achieve unlocking.

[0035] After the unlocking operation is completed, the lock plate 5 can be opened through the unlocking port, which will further open the upper housing 1 and the lower housing 2. When the upper housing 1 and the lower housing 2 are opened, they rotate around the hinge axis 6. At the same time, the hinge axis 6 can slide in the lower hinge hole 221, thereby accommodating the relative rotation of the upper housing 1 and the lower housing 2 and preventing hard interference between them, which could lead to failure to lock or damage.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
