the LED street lamp is widely used because of its energy conservation and environmental protection. With the increase of its usage, the LED street light, more or less, there are some faults, such as the LED street lamp bead piece blackened, what reason is caused? The following leds lamps manufacturers will take you to understand simple reason. One, light emitting diode chip electrode black may have two reasons: 1. Large current. For example, in the process of test, due to their high power instability caused by transient voltage or incorrect operation caused by the large current, electrostatic will only somewhere on a chip. 2. Oxidation. If the electrode is aluminum electrode, it is easy to oxidation and the black. Gold electrode can also be vulcanization and black. Two reasons for this is the main culprit of a led street lamp chips combustion. When installing the led street lamp, we must strictly follow the installation instructions of led street lamp manufacturers.
