Why does LED street light fail?
LED light attenuation refers to that the light intensity of LED street light will be lower than the original light intensity after being lit for some time, and the lower part is led light attenuation. In other words, the light decay of led directly affects the life of LED street lights, and products with fast light decay will darken quickly. Therefore, in many cases, the brightness of the LED street light we installed is relatively low, and the overall function is not very good, resulting in the light failure of street lights.
For LED street lights, it must consume a certain amount of heat under normal operation, so the street lamp shell needs to emit heat. Assuming that the heat dissipation module cannot achieve good heat dissipation, it will lead to the application life and luminous performance of LED street lights. Another problem is that led street lights are used outdoors, which is a disturbing factor for the environment and climate. So now many LED street light manufacturers have done certain treatments on the street light shell, such as anodic treatment protection, or spraying baking paint to avoid the corrosion of acid and alkali substances.
However, there are certain defects. The service life of anodic treatment is not long, and the time is long, and it will oxidize and change color. If it is removed and reinstalled, it will not only take time but also increase the protection cost. The protection cost of baking paint is low, and the protection function is also good. But generally, baking paint has no heat dissipation function. This situation not only does not help, but also reduces the LED luminous power because the heat is blocked in the radiator, and the thermally conductive film cannot be close to the substrate, There will be a certain space on the bonding surface, resulting in a reduction in the power of heat dissipation.
There are certain reasons for the light failure of LED street lights, mainly because of the heat dissipation problem. As long as the whole problem is solved, it can be ensured that the application time of LED street lights is longer, and the light failure problem will also be dealt with. Therefore, in the process of purchasing street lamps, pay attention to the heat dissipation of street lamps to ensure a longer service life of products.
