[0002] In the field of road lighting, LED streetlights are widely used due to their advantages such as energy saving and long lifespan. Currently, LED streetlights typically integrate multiple lamp modules in their lamp heads to achieve wide-area illumination, and the installation stability and ease of maintenance of these lamp modules are key factors affecting streetlight performance.

[0003] In existing technologies, the connection between the lighting module and the lamp holder housing is mostly achieved through bolt fixing or rigid snap-fit ​​connections. Bolt fixing requires tools for installation and disassembly, making the process cumbersome, especially when working at heights, significantly increasing the difficulty and time cost for maintenance personnel. While rigid snap-fit ​​connections require no tools, they are prone to loosening over time, resulting in a loose fit between the lighting module and the lamp holder housing. This not only affects lighting performance but may also create safety hazards. Furthermore, traditional connection structures struggle to simultaneously lock and release multiple lighting modules, further reducing maintenance efficiency. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide an LED street light.

[0005] An LED street light includes a lamp head housing and a sleeve portion disposed at one end of the lamp head housing for engaging with a lamp pole. The lower side of the lamp head housing is provided with several lamp modules. Each lamp module has a plug-in on one side. The lamp head housing has several slots spaced along the same axis on one side. Each plug-in is inserted into a corresponding slot, and a recessed groove is formed on one side of the plug-in. A movable rod is movably disposed on the upper side of the lamp head housing. Several pressure rods are disposed along the length of the movable rod, and each pressure rod presses against a corresponding groove. A locking member is provided on the lamp head housing to lock the movable rod from displacement, thereby keeping the pressure rods pressed against the grooves.

[0006] In one embodiment, the locking member includes a spring and a limiting block. The limiting block is movably disposed on the lamp head housing. The spring abuts between the limiting block and the lamp head housing. The movable rod is provided with a limiting flange. The limiting block is held in place by the elastic force of the spring and is located near the side of the pressure rod.

[0007] In one embodiment, the locking member further includes an adjustment structure for driving the limiting block to make threaded adjustment displacement along the axial direction of the movable rod.

[0008] In one embodiment, the adjustment structure includes a screw and a guide shaft respectively disposed coaxially with the movable rod on the lamp head housing, and the screw and the lamp head housing are rotatably connected by a bearing.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 5 The present invention preferably provides an LED street light, including a lamp head housing 1 and a sleeve portion 2 disposed at one end of the lamp head housing 1 for engaging with a lamp pole. The lamp head housing 1 has a plurality of lamp modules 3 on its lower side. The lamp modules 3 have inserts 4 on one side, and the lamp head housing 1 has a plurality of slots 5 spaced along the same axis on one side. The inserts 4 are inserted into the slots 5 in a corresponding manner, and a groove 6 is recessed on one side of the inserts 4. A movable rod 7 is movably disposed on the upper side of the lamp head housing 1. The movable rod 7 has a plurality of pressure rods 8 along its length direction. The pressure rods 8 are pressed against the grooves 6 in a corresponding manner. The lamp head housing 1 has a locking member 9, which can lock the movable rod 7 to prevent displacement so that the pressure rods 8 remain pressed against the grooves 6.

[0024] Specifically, the initial positioning of the lamp module and the lamp holder housing is achieved through the insertion and mating of the plug-in with the slot. Then, by pushing the movable rod, the pressure rod is moved to press against the slot. The displacement of the movable rod is then locked by the locking component, ensuring that the pressure rod remains pressed against the slot, thus fixing the lamp module. When disassembly is required, the locking component is released from the movable rod, and the movable rod is moved to disengage the pressure rod from the slot, allowing the plug-in to be pulled out of the slot and the lamp module to be removed.

[0025] Furthermore, the locking member 9 includes a spring and a limiting block 92. The limiting block 92 is movably disposed on the lamp head housing 1. The spring abuts against the limiting block 92 and the lamp head housing 1. The movable rod 7 is provided with a limiting flange 93. The limiting block 92 is held in abutting against the limiting flange 93 by the elastic force of the spring and is located near the side of the pressure rod 8.

[0026] Specifically, a guide structure, such as a guide groove, is provided on the lamp head housing to allow the limiting block to move up and down. A spring is installed between the limiting block and the lamp head housing. In its natural state, the spring is compressed, and its elastic force drives the limiting block to move upward. The limiting flange on the movable rod is located near one side of the pressure rod. When the movable rod moves until the pressure rod presses against the slot, the limiting block, under the action of the spring, abuts against the side of the limiting flange near the pressure rod, preventing the movable rod from displacing from the pressure rod in the slot, thus achieving locking. When unlocking is required, the limiting block is pressed down, compressing the spring and causing the limiting block to disengage from the limiting flange, allowing the movable rod to move. This combination of spring and limiting block utilizes the spring's elastic force to keep the limiting block abutting against the limiting flange of the movable rod, thereby achieving automatic locking of the movable rod. This structure is simple and reliable, effectively preventing the movable rod from displacing under external forces such as vibration, ensuring stable pressure of the pressure rod against the slot, and further improving the installation firmness of the lamp module.

[0027] Furthermore, the locking member 9 also includes an adjustment structure for driving the limiting block 92 to make threaded adjustments along the axial direction of the movable rod 7. Further, the adjustment structure includes a screw 94 and a guide shaft 95, which are coaxially arranged on the lamp holder housing 1. The screw 94 is rotatably connected to the lamp holder housing 1 via a bearing. A movable seat 96 is movably sleeved on the guide shaft 95, and the movable seat 96 is threadedly connected to the screw 94. The limiting block 92 is movably disposed on the movable seat 96, and a spring abuts between the limiting block 92 and the movable seat 96.

[0028] Specifically, the adjustment structure drives the limiting block to make threaded adjustments along the axial direction of the movable rod, allowing the contact position of the limiting block with the limiting flange to be adjustable. This not only adapts to the locking requirements of movable rods or limiting flanges of different specifications, but also, after long-term use, compensates for the clearance caused by wear of parts by adjusting the position of the limiting block, ensuring the stability of the locking effect and extending the service life of the structure. The adjustment structure consists of a screw, a guide shaft, and a movable seat. The screw and the movable seat are threaded together, and the guide shaft guides the movable seat, enabling it to move stably along the axial direction of the movable rod, thereby driving the limiting block to move synchronously. This structure offers precise and reliable adjustment. The position of the limiting block can be finely adjusted by rotating the screw, making it easy to operate and precisely controlling the contact force of the limiting block with the limiting flange to ensure the optimal locking effect.

[0029] Furthermore, the upper side of the slot 6 is a guide slope 97. When the pressure rod 8 moves against the guide slope 97, the lamp module 3 remains in a tightly fitted state with the lamp head housing 1. Specifically, the upper side of the slot is designed as a guide slope. When the pressure rod moves against the guide slope, the guide effect of the slope can generate a pushing force on the plug-in towards the lamp head housing during the movement of the pressure rod, making the lamp module and the lamp head housing fit more tightly, reducing the gap between them, avoiding vibration or loosening caused by the gap, and further improving the stability of the installation.

[0030] Furthermore, the lighting module 3 includes a lamp housing 31 with an upper opening, an LED light panel 32 disposed within the lamp housing 31, and a light-transmitting plate 33 detachably covering the opening of the lamp housing 31. The plug-in 4 is disposed on one side of the lamp housing 31. Specifically, the lamp housing is made of weather-resistant material, with an upper opening for mounting the LED light panel, which is fixed inside the lamp housing by bolts or clips. The light-transmitting plate is made of a high-transmittance material, such as tempered glass or acrylic sheet, and is detachably connected to the opening of the lamp housing by clips, bolts, or other means, sealing the LED light panel inside the lamp housing to provide dust and water protection. The plug-in is integrally formed or fixed to one side of the lamp housing by welding, bolts, or other methods.

[0031] Furthermore, the lamp housing 31 can be magnetically attached to one side of the lamp head housing 1. Specifically, the lamp housing is magnetically attached to one side of the lamp head housing, further enhancing the tightness of the fit between the lamp module and the lamp head housing based on the cooperation between the plug and the slot, and the pressure rod and the slot. The magnetic attraction can effectively buffer the impact force caused by vibration, reduce the wear of parts, and at the same time, during the installation process, the attraction force of the magnet can assist in positioning, making it easier for the plug to be inserted into the slot and improving installation efficiency.

[0032] Furthermore, a guide hole 34 is provided on one side of the lamp head housing 1, and the movable rod 7 is movably inserted into the guide hole 34 and moves axially along the guide hole 34. The movable rod is movably inserted into the guide hole of the lamp head housing, and the guide hole guides and limits the displacement of the movable rod, ensuring that the movable rod moves stably along the preset axial direction and avoiding deviation or shaking of the movable rod during movement. This ensures that the pressure rod can be accurately aligned with the slot and press against it, improving the stability and reliability of the entire structure.

[0033] Furthermore, the lamp head housing 1 is equipped with a built-in power supply 10, which is electrically connected to each lamp module 3 via terminal wires. The mating surface between the lamp housing 31 and the lamp head housing 1 has a recessed wire groove 11, within which the terminal wires can be accommodated. The built-in power supply is installed inside the lamp head housing and fixed by a bracket. The LED board of each lamp module is connected to the built-in power supply via terminal wires made of weather-resistant and insulating materials. A wire groove matching the specifications of the terminal wires is machined within the mating surface between the lamp housing and the lamp head housing; the depth and width of the wire groove are sufficient to accommodate the terminal wires. When the lamp module is installed on the lamp head housing, the terminal wires are placed within the wire groove, preventing damage from compression between the lamp module and the lamp head housing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
