What problems should be paid attention to when choosing LED street lights?
With the development of urbanization in my country, more and more attention has been paid to road lighting, which has driven the development of LED street lamps. Some problems need to be paid attention to in structural design, lighting creativity, modeling design, etc., so pay attention when choosing LED street lamps. What are the problems? Let's take a look with the LED panel light manufacturers now!
At present, the prominent problems in the structure and appearance design of LED street lamps:
1. The surface treatment of the material is difficult to handle the erosion of the harsh environment for a long time: the so-called naked LED street light is generally a street light with the radiator directly exposed to the outside. Some owners think that the design of bare lamps is more conducive to heat dissipation, but the premise of such lamps and lanterns longevity is that the lamps must be installed in a relatively clean environment that is not affected by external harsh conditions. In practical applications, LED street lamps are all If it is directly installed outdoors, it may encounter various harsh environments such as acid rain, sandstorm, blizzard and snow, and the service life of the lamp will be greatly reduced, and the lamp must be replaced frequently.
In addition, the naked street lamp is very easy to accumulate dust and snow due to the structural nature of the radiator itself. The dust covering the radiator will greatly reduce the three-color performance of the aluminum alloy, and the surface of the snow appears to be more conducive to heat dissipation. In fact, the heat dissipation of the lamps is sufficient in a cold environment, but a large amount of snow Causes huge pressure on the light pole and reduces damage to the lamp material.
2. The rectangular design does not meet the windproof requirements: The rectangle mentioned here means that the LED street light is in a nearly square shape, and each surface is a large-area plane. Such a plane is better to bear the force. When the wind blows vertically from a certain plane, the plane cannot divide the wind force, thereby causing pressure on the lamp pole and the fixed structure of the lamp.
The performance characteristics of LED street lights developed by famous LED panel light manufacturers:
1. Using 1-3w high-power LED chips, using reduced power to ensure that the life of the entire LED lamp is more than 50,000 hours and the luminous flux maintenance rate.
2. The secondary light distribution lens adopts imported PMMA plus pc material lens, which is UV-resistant and not easy to be broken. The lamp head does not turn yellow after working for a long time. At the same time, the light output rate reaches 92 percent , so that the whole light efficiency can reach 90-120Lm/w or more.
3. Human function light distribution, uniform road lighting.
4. The whole lamp adopts a modular structure to form convection with the air. The power supply cover has holes for air circulation to ensure the service life of the power supply.
