Waterproof performance of LED street lights

Because the working environment of LED street lights is outdoors, with wind and rain, the material of LED street lights is best to be waterproof and corrosive. The anti-corrosion of the LED light pole adopts the surface hot-dip galvanizing and then spraying. The quality of the anti-corrosion meets the requirements. The average thickness of the hot-dip galvanizing layer is not less than 85μm. The spraying of the LED light pole should be made of high-quality outdoor pure polyester plastic powder, with an average thickness of ≥100μm. , The spray layer is uniform, complete, and has a smooth surface, and its adhesion meets the requirements of relevant standards.

The access door under the LED light pole is parallel to the axis of the light pole, 400mm from the ground and a 320mm×120mm access door with a welded ground terminal inside the door; the edges of the door hole and door cover are smooth and flat, and there is a gap between the door cover and door hole after assembly Not more than 2mm, the door cover is interchangeable, and has effective and reliable anti-theft measures. Street lights are an inaccessible part of our lives, but street lights also have many shortcomings. If it involves power outages in the entire area, it will be very inconvenient at that time. Street lights are not only electrical pollution equipment, but also high electricity and maintenance costs. And sometimes if it is not properly protected, it may be stolen, so we must pay special attention to these things when we produce street lights.

Street lights are closely related to our lives. In addition to ordinary street lights, more and more LED street lights have entered our lives. We must pay attention to some details in the installation of LED street lights. Disassembly and assembly of solar LED street lights and selection of assembly locations. The disassembly site should be near the installation site to facilitate transportation after assembly. Try to avoid working on rainy days.

Count the lamps according to the delivery list. Disassemble and check the parts one by one with reference to the packing list and check for damage such as bumps, wear, deformation, and scratches. Light pole components and wearable accessories (such as solar cell modules, lamp caps, etc.) must be placed with soft cushions that are soft to avoid unnecessary damage such as scratches during installation. When the lower light pole assembly is placed, an iron frame is required at its upper end to facilitate the installation of the light pole assembly. Street lights are closely related to our lives.

Through practical applications, it is demonstrated that high-power LED street lights have the advantages of energy saving, environmental protection, long life, adjustable brightness and color temperature, and high color rendering. With the maturity of LED technology and the continuous improvement of efficiency, LED solid-state lighting is the trend and the best solution for energy saving. The energy-saving characteristics of the LED street lamp lighting system are mainly determined by the LED chip and power supply. However, the LED chip and the power supply module are integrated together, and the space is generally small and the heat dissipation is poor. The LED chip and the power supply are heating elements, which makes the ambient temperature higher. Therefore, this article reduces the ambient temperature by improving the heat dissipation conditions of the LED street lamp system, increasing the luminous efficiency of the LED and the efficiency of the power supply, so that the LED power supply and the life of the LED chip can be matched, and real energy saving, environmental protection and long life can be realized.

Let's talk about the main three aspects of research content:

1. Experimental research on thermoelectric relationship of high-power LED street lamps. Taking the high-power LED street lamp with the connection mode first in series and then parallel as the object, the experiment researches the relationship between the power distribution and the temperature distribution under the two power supply modes of constant current and constant voltage. Build an experimental platform for the research on the thermoelectric relationship of LED street lamps and analyze the experimental results. From the results, it is known that under constant current conditions, there is an obvious linear relationship between the LED junction temperature and the forward voltage, which verifies the voltage drop characteristics of the LED, and you can try to measure the junction temperature of the LED with a large current, which is different from the traditional small current measurement. . Compared with constant voltage drive, the total output power of the power supply is more stable in constant current drive. However, due to uneven temperature distribution among multiple LEDs, the corresponding power distribution is constrained by each other. Form a vicious circle. Therefore, the design of heat dissipation balance is of great significance to the improvement of the overall quality of high-power LED street lights.

2. Optimized design of high-power LED street lamp radiator. Taking a company’s 150W high-power LED street lamp as the research object, the thermal resistance network model of the profile radiator is established, and the radiator meeting the heat dissipation requirement is theoretically designed. On this basis, the Icepak thermal analysis software is used to optimize the design. The rationality of the existing radiator design is verified, and the theoretical calculation results are relatively consistent with the optimized results, indicating that theoretical calculations are an important part of the radiator design. Combining software optimization can reduce R&D costs, shorten R&D cycles, and improve R&D efficiency.

3. High-power LED street lamp power module heat dissipation design. Based on the design of the high-power LED power supply circuit, the heat flow path and related thermal resistance are analyzed, and the shortest heat flow path is taken as the goal, two power cooling devices are designed structurally. Aiming at the narrow space for heat dissipation of the power supply, the miniature heat pipe is tried to be used for the heat dissipation of the LED power module. The results show that the two schemes can meet the thermal design requirements of electronic equipment, and the heat dissipation performance of the device using micro heat pipes is about 5℃ better than the other scheme.
