What caused the blackening of the solar led lights bead?

          Solar led lights have been strongly promoted by the state because of energy conservation and environmental protection, and have gradually replaced traditional street lamps. As it is used more and more, there will be some failures more or less. For example, many people ask online why the lampposts of solar led lights are burnt black?

        First of all, the two main reasons for the blackening of led street lights bead are: high current, oxidation, and possibly the quality of the lamp bead or poor heat dissipation. Let us talk about this big current problem first. Many led street lights manufacturers are pursuing the high brightness of solar panel lights and increasing the current to increase the brightness, thereby increasing orders. However, this will cause great trouble to consumers, because as the current increases, the heat of the lamppost of the solar panel lights will increase dramatically. When the current exceeds a certain value, the led street lights bead is likely to be damaged. Even if the led street lights bead is not burnt, it is likely to directly reduce its service life.

         Then another reason for the blackening of the solar panel lights bead may be due to oxidation. If the electrode is an aluminum electrode, it is easily oxidized and blackened. Gold electrodes may also be vulcanized and blackened. Of course, in addition to these two main reasons, there are also some secondary reasons, such as the quality of the solar pole lights beads is not good or the heat is not good. The things that are cheap and good are still in the minority, the solar pole lights beads are also a penny, and the quality of the lamps with too low price will be worse.

        There is also a heat dissipation problem. The heat dissipation of solar pole lights is very important. If the heat dissipation is not good, it will not only bring damage to the lamp beads, but also have a very influential effect on the whole solar street light price head.
