The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 3 The road lighting lamp of this utility model embodiment includes a base frame 100, a heat sink 200, a wire cover 300, a lamp board 400, and wires. A heat sink 200 is disposed on a base frame 100. The heat sink 200 includes a heat-conducting plate 210 and at least three heat dissipation fins 220. The heat dissipation fins 220 are disposed on one side of the heat-conducting plate 210 and are spaced apart along their thickness direction. Each heat dissipation fin 220 includes two adjacent first heat dissipation fins 221 and at least one second heat dissipation fin 222. The heat-conducting plate 210 and the two first heat dissipation fins 221 form a wire receiving groove 201, which extends along the length of the heat dissipation fins 220. A wire cover 300 is detachably disposed on the heat sink 200 and covers the opening of the wire receiving groove 201. A lamp plate 400 is disposed on the other side of the heat-conducting plate 210. A wire is disposed on the heat sink 200 and located in the wire receiving groove 201, and the wire is in communication with the lamp plate 400.

[0023] The two first heat dissipation fins 221 and the heat dissipation plate on the heat sink 200 form a wire receiving groove 201. The wire cover 300 is detachably installed on the heat sink 200 to cover the opening of the wire receiving groove 201. The structure of the heat sink 200 itself, together with the wire cover 300, realizes the accommodation and waterproof protection of the wire, reducing the number of parts and lowering the production cost. The detachable wire cover 300 also facilitates the laying of wires and subsequent inspection and maintenance by construction personnel, making installation and maintenance more convenient.

[0024] Specifically, the lamp panel 400 is connected to the heat sink, so that the heat generated by the lamp panel 400 can be directly transferred to the heat sink for air cooling, thereby improving the heat dissipation efficiency of the lamp panel 400 and simplifying the structure of the road lighting lamp.

[0025] Specifically, there are two first heat dissipation fins 221 and fourteen second heat dissipation fins 222. It is conceivable that the number of second heat dissipation fins 222 could also be one, two, or more, and those skilled in the art can choose according to actual needs.

[0026] Reference Figure 3 In this embodiment, the two ends of the wire cover 300 are detachably connected to two first heat dissipation fins 221 in a one-to-one correspondence, and the wire cover 300 is offset from the second heat dissipation fins 222. The wire cover 300 is detachably connected to the two first heat dissipation fins 221, without needing to be connected to the second heat dissipation fins 222. This allows the wire cover 300 to have a smaller width. The wire cover 300 is detachably mounted using the two first heat dissipation fins 221, resulting in a simple structure that is easy to implement.

[0027] Reference Figure 2In this embodiment, the first heat dissipation fin 221 is provided with a slot 2211, which extends along the length of the heat dissipation fin 220. The wire cover 300 is provided with a protrusion 310, which is engaged with the slot 2211. The slot 2211 is located at the end of the first heat dissipation fin 221 away from the heat conduction plate 210.

[0028] The wire cover 300 is detachably mounted to the two first heat dissipation fins 221 using a snap-fit ​​method, thus achieving good fixation and simple assembly / disassembly. Alternatively, a slot 2211 could be provided in the wire cover 300, and a protrusion could be provided in the first heat dissipation fins 221 for a snap-fit ​​connection; or a magnet could be provided in the wire cover 300, and an iron block could be provided in the first heat dissipation fins 221, with the magnet and iron block magnetically attracting each other for a detachable connection.

[0029] Reference Figure 3 In the implementation example, the wire cover 300 has a U-shaped cross-section along the length of the heat dissipation fin 220. The wire cover 300 is provided with limiting ribs 320, which extend along the length of the heat dissipation fin 220 and are opposite to the first heat dissipation fin 221. The limiting ribs 320 and the locking protrusions 310 are spaced apart along the depth direction of the wire receiving groove 201. When the wire cover 300 is inserted into the first heat dissipation fin 221 along the depth direction of the wire receiving groove 201, the limiting ribs 320 can limit the locking position, reducing the risk of the locking protrusions 310 and the locking groove 2211 becoming misaligned due to excessive insertion of the wire cover 300.

[0030] It should be understood that both the heat sink 200 and the wire cover 300 are made of metal, such as aluminum alloy or stainless steel.

[0031] Specifically, since the cross-section of the wire cover 300 is U-shaped, that is, the two ends of the wire cover 300 have a certain elastic deformation capability, it is convenient for the wire cover 300 to be detachably connected to the first heat dissipation fin 221.

[0032] Specifically, the end of the first heat dissipation fin 221 away from the heat conduction plate 210 is a free end with a certain degree of elasticity. Since the slot 2211 is located at the end of the first heat dissipation fin 221 away from the heat conduction plate 210, it is convenient for the wire cover 300 to be detachably connected to the first heat dissipation fin 221.

[0033] Reference Figure 3In this embodiment, the heat-conducting plate 210 is provided with a first thickness region 211 and a second thickness region 212. A first heat dissipation fin 221 is connected to the first thickness region 211, and a second heat dissipation fin 222 is connected to the second thickness region 212. The bottom wall of the wire receiving groove 201 is located in the first thickness region 211. The thickness of the heat-conducting plate 210 in the first thickness region 211 is greater than its thickness in the second thickness region 212. The heat-conducting plate 210 has a connector mounting hole on the bottom wall of the wire receiving groove 201. The thicker bottom wall of the wire receiving groove 201 provides sufficient thickness for installing the waterproof connector 500 and improves the waterproof effect.

[0034] Reference Figure 3 In this embodiment, the heat-conducting plate 210 has a thickening rib 213 extending along the length of the heat dissipation fins 220. A portion of the second heat dissipation fins 222 are connected to the thickening rib 213, which has screw holes. The second thickness region 212 is relatively thin; if screw holes were directly provided, the heat dissipation plate could easily be punctured, affecting the waterproofing effect of the heat sink 200. Therefore, the thickening rib 213 can be provided where screws are needed to prevent punctures in the exposed areas of the heat-conducting plate 210. Some of the second heat dissipation fins 222 are connected to the thickening rib 213, making the structure of the heat sink 200 relatively compact.

[0035] Reference Figure 2 In this embodiment, a waterproof connector 500 is also included. The waterproof connector 500 is disposed in the connector mounting hole, and the wire is connected to the lamp board 400 through the waterproof connector 500. By providing the waterproof connector 500, even if water accidentally enters the wire receiving groove 201, the risk of water flowing to the lamp board 400 can be reduced, thereby improving the waterproof performance.

[0036] Specifically, the lamp board 400 is electrically connected to the waterproof connector 500 to enable the wires to conduct electricity between the lamp board 400 and the conductor.

[0037] Reference Figure 1 In this embodiment, the base frame 100 includes a mounting base 110 and an end cap 120. One end of the heat sink 200 along the length of the heat sink fins 220 is mounted on the mounting base 110, and the mounting base 110 covers the wire receiving groove 201 near one end of the mounting base 110. The end cap 120 is mounted on the other end of the heat sink 200 along the length of the heat sink fins 220, and the end cap 120 covers the wire receiving groove 201 near one end of the end cap 120.

[0038] Both the base frame 100 and the end cap 120 provide some protection and water-blocking for the wire receiving groove 201. The aforementioned road lighting fixtures, namely the mounting base 110 and the end cap 120, are respectively connected to the opposite ends of the heat sink 200. When the heat sink 200 is made of different lengths along the length of the heat sink fins 220, the mounting base 110 and the end cap 120 can be used interchangeably to form road lighting fixtures of different specifications. This allows the base frame 100 to be used with various specifications of road lighting fixtures, resulting in good component interchangeability.

[0039] Specifically, the mounting base 110 is attached to one end of the heat sink 200 by screws, and the end cover 120 is attached to the other end of the heat sink 200 by screws. The heat sink 200 is used to form the connection structure between the mounting base 110 and the end cover 120. The heat sink 200 also serves as the mounting structure for the lamp panel 400. The structure of the road lighting lamp is relatively compact and has fewer parts.

[0040] In this embodiment, a power supply box is detachably mounted on the side of the heat sink 200 facing away from the lamp panel 400. In this embodiment of the road lighting lamp, the power supply box can be optionally mounted on the back of the heat sink 200, or the power supply can be optionally installed inside the lamp post. When the power supply box is optionally mounted on the back of the heat sink 200, it is installed to the back of the heat sink 200 by screws; when the power supply is installed inside the lamp post, the power supply box does not need to be installed on the back of the heat sink 200, and the power supply is electrically connected to the wires.

[0041] It is conceivable that the power supply box can also be detachably mounted to the heat sink 200 via, for example, bolt and nut assembly.

[0042] Specifically, the mounting base 110 is provided with a wire through hole so that the wire in the wire receiving groove 201 can pass through, so that the wire can be inserted into the lamp post.

[0043] Reference Figure 2 In this embodiment, the heat sink 200 is a one-piece molded structure, which reduces the number of parts of the road lighting lamp, thereby reducing assembly difficulty and manufacturing costs.

[0044] Reference Figure 3 In this embodiment, the thickness of the first heat dissipation fin 221 is greater than the thickness of the second heat dissipation fin 222. This can save material on the heat sink 200, ensure that the first heat dissipation fin 221 has sufficient structural strength to secure the mounting cover 300, and enable the second heat dissipation fin 222 to have better heat dissipation performance.

[0045] Specifically, the thickness of the heat dissipation fins 220 gradually decreases along the direction away from the heat conduction plate 210, which facilitates processing.

[0046] Specifically, a lens is installed on the side of the lamp panel 400 away from the heat sink 200 to facilitate adjustment of the light output range.

[0047] Specifically, the base frame 100 also includes legs, which are rotatably connected to the heat sink 200. The legs can be used to support and install street lighting lamps. The legs and the heat sink 200 have rotation positions for easy adjustment of the leg angle.

[0048] Optionally, in some embodiments, the second heat dissipation fin 222 extends in a wavy shape away from the heat-conducting plate 210, while the first heat dissipation fin 221 extends in a straight shape away from the heat-conducting plate 210. The aforementioned heat dissipation fin 220 structure, with the second heat dissipation fin 222 extending in a wavy shape (i.e., the cross-section of the second heat dissipation fin 222 is wavy), significantly increases the air contact area of ​​the second heat dissipation fin 222 while maintaining a constant height, thereby improving heat dissipation efficiency. The first heat dissipation fin 221 extends in a straight shape, facilitating a detachable connection with the wire cover 300.

[0049] Specifically, the heat sink 200 is a profile structure that extends along the length of the heat sink fins, so that even when the cross-section of the second heat sink fin 222 is wavy, the processing difficulty of the heat sink 200 will not be increased.

[0050] Optionally, in other embodiments, the second heat dissipation fin 222 is provided with ventilation holes along its thickness direction, which facilitates increasing the air contact area of ​​the second heat dissipation fin 222 without affecting the structure of the first heat dissipation fin 221.
