In many cases, we will encounter this problem, that is, the street lamp is used, the brightness is relatively low, the overall effect is not very good, there is a situation of road light decay, then what causes the road light to decline? Today, let's take a look at the lighting editor.

For the LED street lamp, it will emit a certain amount of heat under normal operating conditions. Therefore, for the street lamp housing, it is necessary to dissipate heat. If the heat dissipation module cannot achieve good heat dissipation, it will lead to the service life of the LED street lamp and Luminous performance. At present, the serious light decay of led street lights is caused by these factors. Another problem is that led street lights are used outdoors. For the interference factors of the environment and climate, many manufacturers have done some processing on the street lamp shells, for example. Anode treatment protection, or spray paint to avoid acid and alkali erosion. There are certain disadvantages in the two ways. The anode treatment has a short life span. It takes a long time to oxidize and discolor. If it is removed and reinstalled, it will not only take time to increase the maintenance cost, but also the protection cost of the paint is low, and the protection function is also Better, but the general baking paint does not have a heat-dissipating function. This situation will not help, but it will be blocked by heat in the heat sink, so that the LED light power is reduced, and the heat-conducting film can not really be in close contact with the substrate, and the bonding surface will exist. A certain gap, resulting in reduced heat dissipation efficiency.

There are also some reasons for the light decay of LED street lamps. The main reason is the heat dissipation problem. Only when the whole problem is solved can the LED street lamp be used for a longer period of time, and the light decay problem will be solved. Therefore, in the process of purchasing street lamps, pay attention to the heat dissipation of street lamps to ensure the longevity of the products.
