Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor lighting, in particular to a high-power LED street lamp module with high heat conductivity. Background Art

[0002] Semiconductor lighting is an emerging lighting technology. Its basic device is the light-emitting diode (LED), which is a semiconductor solid light-emitting device. It uses solid semiconductor chips as light-emitting materials. In the semiconductor, the excess energy is released by the recombination of carriers, causing photon emission, and directly emitting red, yellow, blue, green, cyan, orange, purple, and white light. Semiconductor lighting products are lighting fixtures made using LED as a light source. Semiconductor lighting has the remarkable characteristics of high efficiency, energy saving, environmental protection, and easy maintenance. It is an effective way to achieve energy conservation and emission reduction. It has gradually become another revolution in lighting sources after incandescent lamps and fluorescent lamps in the history of lighting.

[0003] The LED itself is composed of a combination of lamp beads. If one or part of them is not lit, the entire lamp will inevitably become dim. LED street lamps that work in high-temperature environments for a long time are more likely to have LED lamp bead burnout accidents. Therefore, there is a need for a street lamp module that improves the heat dissipation structure of high-power LED lighting modules to reduce the operating temperature and prevent LED burnout and light decay. Utility Model Content

[0004] The utility model aims to provide a high-power LED street lamp module with high heat conduction.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a mounting base, a mounting lamp pole is fixedly provided on the top wall of the mounting base, a cylindrical lamp mounting shell is fixedly provided on the outer wall at the end of the mounting lamp pole, a high-power lighting module is fixedly provided on the bottom wall of the lamp mounting shell, a metal heat-saturating cylinder that fits the lighting module is fixedly provided on the inner wall of the lamp mounting shell, a metal heat-conducting pipe is buried inside the metal heat-saturating cylinder, the metal heat-conducting pipe is connected to a liquid storage tank with a liquid pump, the liquid storage tank is installed against the inner wall of the mounting lamp pole, the mounting lamp pole is made of metal heat-conducting material, and a plurality of cooling fins are fixedly provided on the outer wall of the mounting lamp pole.

[0007] By adopting the above technical scheme, in actual use, an elastic heat-conducting layer can be set between the lighting module and the metal heat-diffusion tube or thermal grease can be applied to keep the two in close contact. The heat accumulated inside the lighting module can be discharged through the effect of heat exchange, which can effectively reduce the working temperature of the lighting module. The liquid pump can cyclically transport the coolant in the liquid storage tank to the metal heat-conducting pipe and then return it to the liquid storage tank. The heat of the metal heat-diffusion tube is transferred to the liquid storage tank through heat exchange. The liquid storage tank is tightly connected to the installation lamp pole and combined with the heat dissipation fins to effectively dissipate heat into the surrounding environment, which has a good cooling effect and effectively avoids the burning of LED lamp beads. The heat dissipation fins are arranged at a position far away from the lighting module to ensure high-efficiency heat dissipation of the lighting module while avoiding blocking the illumination range of the lighting module.

[0008] Furthermore, the heat dissipation fins are vertically arranged along the gravity direction, the heat dissipation fins are parallel to each other and arranged around the lamp pole at equal intervals, a fan mounting plate is connected between adjacent heat dissipation fins, and a heat dissipation fan is fixedly arranged on the outer wall of the fan mounting plate.

[0009] By adopting the above technical solution, the cooling fan is installed between adjacent cooling fins. When the cooling fan rotates, a flowing airflow can be formed between the cooling fins. Through the effect of thermal convection, the heat on the surface of the cooling fins can be quickly taken away and discharged into the surrounding environment, thereby effectively improving the heat dissipation efficiency of the cooling fins and further reducing the operating temperature of the lighting module.

[0010] Furthermore, an open rainwater collecting cover is fixedly provided on the top wall of the lamp pole installation, a rainwater opening connected to the lamp pole installation is formed on the bottom wall of the rainwater collecting cover, a liquid receiving funnel is extended from one side of the inner wall of the liquid storage tank close to the rainwater collecting cover and abuts against the inner wall of the lamp pole installation, and the bottom end of the liquid receiving funnel is connected to the internal cavity of the liquid storage tank.

[0011] By adopting the above technical solution, the rainwater collection cover can collect rainwater, which flows smoothly from the rainwater opening into the liquid receiving funnel and then into the liquid storage tank for collection and storage, thereby playing the effect of additionally replenishing cooling water for the liquid storage tank, further ensuring the normal operation of the water cooling system.

[0012] Furthermore, a magnetic cover plate covering the rainwater opening is hingedly provided on the inner wall of the mounting lamp pole, and a limiting block is spaced and positioned on a side of the magnetic cover plate away from the rainwater opening, and the limiting block is fixedly provided on the inner wall of the mounting lamp pole.

[0013] By adopting the above technical solution, the magnetic cover can effectively absorb and close the rainwater opening through magnetic attraction, thereby preventing the evaporation loss of cooling water in the liquid storage tank. Only when the rainwater in the rainwater collection cover accumulates to a sufficient amount of water will the magnetic cover be pushed open under the action of gravity and then flow into the liquid storage tank. The limit block can effectively block the opening angle of the magnetic cover, preventing the magnetic cover from rotating too far away from the rainwater opening and unable to be magnetically reset, thereby ensuring the stable and normal operation of the equipment.

[0014] Furthermore, a rainwater collection port is provided at the top of the rainwater collection cover, and a porous filter plate covering the rainwater collection port is fixedly provided on the top wall of the rainwater collection cover.

[0015] By adopting the above technical solution, the setting of the porous filter plate has a good filtering effect. While not hindering the rainwater collection cover from collecting rainwater, it prevents debris from entering the rainwater collection cover and the liquid storage tank, thereby ensuring the stability of the liquid cooling system.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] 1. Metal heat sink, metal heat pipe, liquid storage tank and heat dissipation fins are used to effectively prevent the LED lamp beads from burning and have a good cooling effect;

[0018] 2. The fan mounting plate and cooling fan are used to effectively improve the heat dissipation efficiency of the cooling fins and further reduce the working temperature of the lighting module;

[0019] 3. A rainwater collection cover, a limit block and a magnetic cover are used to effectively collect rainwater while avoiding evaporation loss of cooling water in the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS
