What is the cause of light decay of Led street light

In many cases, we will encounter this problem, that is, the brightness of the street lamp is relatively low when the street light is used, and the overall effect is not very good. There is a situation of street LED light decay, so what is the reasons causing that?

Regarding led street lights, under normal operating conditions, they will declare a certain amount of heat. For LED street lamp housings, they need to emit heat. Assuming that the heat dissipation module cannot achieve good heat dissipation, it will lead to the life of the led street lighting fixture. And luminous performance. Nowadays, the serious light decay of LED street lamps is caused by these elements. Another problem is that LED street lighting lamps are used outdoors. Regarding the disturbing elements of the environment and climate, many led lights street manufacturers have done certain treatments on street LED lamp housings, for example. Anodize protection, or spray paint to avoid corrosion of acid and alkali substances.

The two methods also have certain defects. The life span of anodizing treatment is not long. If the time is long, 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 varnish is lower, and the protection function is also better, but the general baking varnish has no heat dissipation function. This situation not only does not help, but because the heat energy is blocked in the radiator, the LED luminous power is reduced, and the thermal conductive film cannot really adhere to the substrate, and the bonding surface will exist. Now that there is a certain open space, the power of heat dissipation is also reduced.

There are certain reasons for the light decay of LED road lamps, mainly because of the heat dissipation problem. As long as the whole problem is dealt with, we can ensure that the use of LED street/road llights lasts longer and the light decay problem will also be dealt with in a certain way. Therefore, in the process of buying street lighting LED lamps, pay attention to the heat dissipation of street lights to ensure that the product has a longer service life.
