Description

Technical Field

[0001] This utility model relates to the field of LED street light technology, specifically to a double-sided air convection heat dissipation LED street light. Background Technology

[0002] With the acceleration of urbanization, LED streetlights have been widely used in urban road lighting due to their high efficiency, energy saving, and long lifespan.

[0003] For example, Chinese Patent Publication No. CN202040708U discloses an LED street light with heat dissipation function. This existing device utilizes the working thermal effect of the LED and the chimney effect formed by the hollow channel in the center of the light pole to automatically generate gas flow, enhancing the heat dissipation capacity of the LED street light and ensuring the working life of the LED. However, this existing device mainly relies on the working thermal effect of the LED and the chimney effect formed by the hollow channel in the center of the light pole for heat dissipation. However, this heat dissipation method may be limited by environmental conditions, such as wind speed and temperature, resulting in unstable heat dissipation effect. Especially in high temperature, windless, or low wind speed environments, the heat dissipation effect may be greatly reduced, thus affecting the working life of the LED. Moreover, in this existing device, the assembly process of the LED street light is relatively complex, requiring precise operation by professional personnel. This not only increases installation costs but may also affect installation efficiency. In addition, because the installation and adjustment of the LED street light in this existing device are relatively fixed, it lacks flexibility. This may lead to the street light not achieving optimal lighting or heat dissipation effects in certain installation scenarios. Utility Model Content

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0031] Example 1:

[0032] like Figures 1-6 As shown, the dual-sided air convection heat dissipation LED street light of this embodiment includes a fixing base 1, a supporting light pole 2 is provided at the top of the fixing base 1, a light pole head 3 is provided at the top of the supporting light pole 2, and a lighting component 4 is provided at the top of the light pole head 3.

[0033] The lighting assembly 4 includes a power supply box 41 mounted outside the mounting base 1. A base box 42 and a waterproof wiring harness 47 are mounted outside the power supply box 41. A driver power supply 45 is housed within the power supply box 41, and an LED light panel 43 and a lens 44 for lighting are housed within the base box 42. By integrating components such as the power supply box 41, base box 42, waterproof wiring harness 47, driver power supply 45, LED light panel 43, and lens 44, the lighting function is completed, improving the overall integrity and stability of the streetlight. The waterproof wiring harness 47 effectively prevents internal components from getting damp, ensuring reliable operation of the streetlight.

[0034] The base box 42 is equipped with convection heat dissipation fins 5 to cool the driving power supply 45 in the power supply box 41 and the LED light board 43 and lens 44 in the base box 42. The convection heat dissipation fins 5 can quickly dissipate the heat generated during lighting, effectively preventing the components from being damaged due to overheating and extending the service life of the street light.

[0035] An auxiliary assembly mechanism 7 is provided between the power supply box 41 and the base box 42 to facilitate their assembly. The auxiliary assembly mechanism 7 includes a connecting frame 71 slidably disposed outside the power supply box 41, a rack 77 slidably disposed within the connecting frame 71, a connecting plate 78 fixedly disposed outside the rack 77, and a insertion slot in the base box 42 for inserting the connecting plate 78. Through its internal components such as the connecting frame 71, rack 77, and connecting plate 78, the assembly process of the power supply box 41 and the base box 42 is simplified, installation efficiency is improved, and a stable connection between the two is ensured.

[0036] Furthermore, the lighting assembly 4 also includes a control device 46 disposed in the base box 42 for controlling the LED light panel 43 to be turned on and off.

[0037] Furthermore, the auxiliary assembly mechanism 7 includes a connecting column 72 rotatably disposed in the connecting frame 71, with a gear 74 fixed to the outside of the connecting column 72, and the gear 74 meshing with a rack 77. The sliding of the connecting plate 78 is achieved through the meshing of the gear 74 and the rack 77.

[0038] Furthermore, the auxiliary assembly mechanism 7 also includes a worm gear 73 disposed outside the connecting column 72 and a worm 75 rotatably disposed in the connecting frame 71, the worm 75 meshing with the worm gear 73. The addition of the worm gear 73 and the worm 75 makes the rotation of the connecting column 72 more stable and reliable, improving the assembly accuracy. A connecting handle 76 for rotating the worm 75 is fixed outside the worm 75.

[0039] Example 2:

[0040] Compared to Example 1, such as Figure 7 As shown, and in conjunction with Embodiment 1, a mounting adjustment mechanism 6 is further provided between the power supply box 41 and the lamp post head 3 for their installation. The mounting adjustment mechanism 6 includes a fixed toothed plate 61 disposed outside the power supply box 41 and a movable toothed plate 62 disposed outside the lamp post head 3. The movable toothed plate 62 has a connecting groove 63 for adjusting the installation. The fixed toothed plate 61 and the movable toothed plate 62 engage. Through the engagement of the fixed toothed plate 61 and the movable toothed plate 62, and the adjustment function of the connecting groove 63, the mounting adjustment mechanism 6 makes the installation between the power supply box 41 and the lamp post head 3 more flexible and diverse.

[0041] The mounting and adjusting mechanism 6 also includes at least two sets of mounting bolts 64. Each mounting bolt 64 has a connector 65 on its exterior, allowing it to slide within a connecting groove 63. The mounting bolts 64 and connectors 65 within the connecting groove 63 further ensure a stable connection between the power supply box 41 and the lamp post head 3. The fixing tooth plate 61 has mounting grooves for threaded connection of the mounting bolts 64, enabling the mounting bolts 64 to be securely fixed to the fixing tooth plate 61.

[0042] In actual operation, when installing this street light, the following steps should be taken first:

[0043] Insert the power supply box 41 into the base box 42, merging the two together. To ensure a stable connection, rotate the connecting handle 76, causing the worm gear 75 to rotate. The worm gear 75 then drives the meshing worm wheel 73 to rotate, causing the connecting post 72 to rotate accordingly. This action simultaneously rotates the gear 74, causing the two sets of racks 77 meshing with the gear 74 to slide in opposite directions within the connecting frame 71. Finally, the connecting plate 78 engages with the insertion slot in the base box 42, quickly completing the assembly of the connecting frame 71 and the connecting post 72.

[0044] Next, adjust the assembly method of the lamp post head 3 and the power supply box 41 according to the usage requirements. If parallel installation is required, engage the movable toothed plate 62 and the fixed toothed plate 61 in parallel, and fine-tune the installation angle of the power supply box 41. After adjustment, rotate the connector 65 so that the mounting bolt 64 passes through the connecting groove 63 and is threaded into the mounting groove in the fixed toothed plate 61 to complete the assembly. If vertical installation is required, place the lamp post head 3 and the power supply box 41 vertically so that the movable toothed plate 62 engages with the fixed toothed plate 61, and make fine adjustments as well.

[0045] After assembly, the lamp post head 3 is installed onto the outside of the supporting lamp post 2 and propped up. Once the power is connected, the streetlight begins to illuminate under the coordinated action of the driver power supply 45, LED light panel 43, and lens 44. Simultaneously, the waterproof wiring harness 47 effectively prevents moisture damage to the internal components of the power supply box 41 and the base box 42.

[0046] Furthermore, the convection heat dissipation fins 5 can quickly dissipate the heat generated during lighting, preventing the LED light panel 43, lens 44, and driver power supply 45 from burning out due to overheating.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
