[0039] Embodiment 1

[0040] Please refer to Figures 1 to 3 , Embodiment 1 of the present invention is: An LED street lamp, including a fixing frame 1, a main housing 2 and a controller 3. The fixing frame 1 is connected to the main housing 2. Optionally, the fixing frame 1 and the main housing 2 are an integrally formed integral structure;

[0041] A light source cavity 21 is provided in the main housing 2. An light outlet communicating the light source cavity 21 with the outside is provided on the bottom surface of the main housing 2.

An external thread section 51 is provided on the peripheral wall of the installation table 5. A plurality of jacks 52 are provided on the top surface of the installation table 5. A first conductive member 61 electrically connected to the LED lamp board 41 is provided in a part of the jacks 52, and a second conductive member 62 for electrically connecting to an external power supply is provided in another part of the jacks 52. A part of the second conductive member 62 extends into the light source cavity 21; Specifically, the fixing frame 1 is located at one end of the main housing 2. The fixing frame 1 is a hollow structural member with both ends penetrating. The hollow area of the fixing frame 1 communicates with the light source cavity 21. An external cable (not shown in the figure) passes through the hollow area of the fixing frame 1 and penetrates into the light source cavity 21 and is electrically connected to the second conductive member 62.

[0042] The controller 3 includes a housing 31, a locking ring 32, and a driving board (not shown in the figure). The driving board is provided with a control chip (IC), a rectifying circuit, a filtering circuit, a feedback circuit, a protection circuit, etc. The driving board is a commonly used component in the technical field of LED lamps and belongs to the existing mature technology, so it will not be elaborated here. The locking ring 32 is rotatably connected to the bottom of the housing 31. The locking ring 32 has an internal thread section 321 for cooperating with the external thread section 51. The driving board is disposed inside the housing 31. The bottom of the housing 31 is provided with a plurality of conductive pins 33 electrically connected to the driving board. At least part of the conductive pins 33 is located in the hollow area of the locking ring 32. When the controller 3 is connected to the main housing 2 through the cooperation of the internal thread section 321 and the external thread section 51, a part of the conductive pins 33 is inserted into the jack 52 to contact and conduct with the first conductive member 61, and another part of the conductive pins 33 is inserted into the jack 52 to contact and conduct with the second conductive member 62.

[0043] To improve the waterproof ability of the LED street lamp, a first sealing ring 71 is provided between the housing 31 and the mounting table 5. The top of the first sealing ring 71 abuts against the bottom surface of the housing 31, and the bottom of the first sealing ring 71 abuts against the top surface of the mounting table 5. In this embodiment, the bottom surface of the housing 31 has a convex ring 311 protruding downward. The cross section of the first sealing ring 71 is concave-shaped, and the first sealing ring 71 is installed on the convex ring 311.

[0044] To facilitate the processing and manufacturing of the main housing 2 and simplify the design of the production mold of the main housing 2, optionally, the mounting table 5 includes a mounting block 53 and a boss 54. The main housing 2 and the boss 54 are an integrally formed structure. The mounting block 53 is located above the boss 54 and is fixedly connected to the boss 54. The external thread section 51 is provided on the peripheral wall of the mounting block 53. A ring groove 531 is provided on the bottom peripheral wall of the mounting block 53. The ring groove 531 is located below the external thread section 51. The diameter of the inner wall of the ring groove 531 is smaller than the outer diameter of the external thread section 51. The jack 52 is provided on the mounting block 53. A window 541 communicating the light source cavity 21 with the jack 52 is provided on the top of the boss 54. The first conductive member 61 and the second conductive member 62 respectively penetrate into the light source cavity 21 through the window 541.

[0045] In this embodiment, the mounting block 53 and the boss 54 are tightly connected by screws. The mounting block 53 is provided with mounting holes 532 for mounting the screws. A second sealing ring 72 is provided at the connection between the mounting block 53 and the boss 54. The setting of the second sealing ring 72 can prevent external moisture and dust from reaching the window 541 through the gap between the mounting block 53 and the boss 54 and invading the light source cavity 21, which is beneficial to ensuring the waterproof performance of the LED street lamp.

[0046] In one or more embodiments, the first conductive member 61 includes a contact member and a wire connected to each other. The contact member is fixed on the mounting block 53. One end of the contact member is located in the jack 52, the other end of the contact member is welded to the wire, and the wire is welded and conducted with the LED lamp board 41. The contact member can be a metal structural member, a spring pin, etc. Similarly, the specific structure of the second conductive member 62 can be the same as that of the second conductive member 62, except that the wire of the second conductive member 62 is connected to an external cable.

[0047] Embodiment Two

[0048] Please refer to Figure 4 and Figure 5 As shown in [figures], Embodiment Two of the present invention is a further improvement based on Embodiment One. Specifically: The mounting block 53 has a drain hole 533 disposed obliquely. One end of the drain hole 533 communicates with the jack 52 to form a first communication port, and the other end of the drain hole 533 communicates with the annular groove 531 to form a second communication port. The first communication port is higher than the second communication port; for the drain hole 533 communicating with the jack 52 provided with the first conductive member 61, the lower edge of the first communication port is flush with the top edge of the first conductive member 61; for the drain hole 533 communicating with the jack 52 provided with the second conductive member 62, the lower edge of the first communication port is flush with the top edge of the second conductive member 62. Since the mounting block 53 is independent of the main housing 2, the jack 52, the drain hole 533, and the external thread section 51 on the mounting block 53 can all be conveniently processed and formed.

[0049] LED street lamps are generally installed outdoors. When the controller 3 fails and the user removes the damaged controller 3, if the controller 3 cannot be reinstalled on the main housing 2 in time (for example, it takes a certain amount of time to repair the controller 3, and it takes additional waiting time to purchase a new controller 3, etc.), during this period, if it rains, external moisture and dust will enter the jack 52. When the controller 3 is reinstalled later, the accumulated water and dust in the jack 52 will undoubtedly affect the electrical connection and even easily cause safety accidents. The setting of the drain hole 533 can prevent rainwater from accumulating in the jack 52, and the rainwater entering the jack 52 is directly discharged from the jack 52 through the drain hole 533.

[0050] However, due to factors such as the surface tension, adsorption force, and van der Waals force of water droplets, sometimes some small water masses remain in the socket 52. In order to clean these residual water masses and dust in the socket 52, as a preferred embodiment, the LED street lamp also includes a water-absorbing wiper 8 for cleaning the socket 52. The water-absorbing wiper 8 includes a support body and a cotton product disposed on the support body, and the cotton product includes but is not limited to cotton balls, cotton fabrics, etc. It is easy to understand that after the controller 3 is disassembled from the main housing 2, during the period before the repaired controller 3 is reassembled on the main housing 2, when the ambient weather is relatively clear and it is not raining, the user does not need to use the water-absorbing wiper 8 to clean the socket 52. At this time, the user can directly install the controller 3 on the main housing 2 without any other operation, which is convenient for the user to operate.

[0051] The cotton product covers a partial area or the entire area of ​​the support body. When the cotton product covers a partial area of ​​the support body, it is preferably located at the end of the support body. In actual application, a cotton swab can be directly used as a water-absorbing wiper 8.

[0052] In order to store the water-absorbing wiper 8, the optional LED street lamp also includes a limit cover 9, which is buckled on the top of the shell 31, and the water-absorbing wiper 8 is placed in the placement space formed by the limit cover 9 and the shell 31. Specifically, the limit cover 9 includes a top plate 91 and a surrounding wall 92 arranged along the edge of the top plate 91, and the surrounding wall 92 has a protrusion 93 protruding inward, and the surrounding wall of the shell 31 is provided with a pit that cooperates with the protrusion 93. When the user replaces the new controller 3, the water-absorbing wiper 8 can be taken out by opening the limit cover 9. In order to control costs and facilitate the user to open the limit cover 9, the limit cover 9 is preferably a blow-molded structural part.

[0053] In this embodiment, the conductive pin 33 is a spring pin, the first conductive member 61 and the second conductive member 62 are metal columns respectively, the first conductive member 61 and the mounting block 53 are insert-molded into an integral structure, thereby ensuring the sealing effect between the first conductive member 61 and the mounting block 53, and the second conductive member 62 and the mounting block 53 are insert-molded into an integral structure, thereby ensuring the sealing effect between the second conductive member 62 and the mounting block 53.

[0054] In order to enable the water-absorbing wiping member 8 to clean the drain hole 533, in one or more embodiments, the top surface of the metal post has a guiding inclined surface, and the inclination direction of the guiding inclined surface is the same as the inclination direction of the drain hole 533. The support body in the water-absorbing wiping member 8 is a rubber rod or a wire. The rubber rod can be a silicone rubber rod or the like. The rubber rod and the wire can be deformed. Under the guidance of the guiding inclined surface, the support body will deform, and at least part of the cotton product will extend into the drain hole 533. Optionally, in the actual operation process, the water-absorbing wiping member 8 enters from the insertion hole 52 and exits from the drain hole 533.

[0055] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present invention.
