Hello everyone, I am the beautiful lanterns. Today, let ’s introduce the problem of the black core LED lamp beads of LED lamp beads. The following is the summary of this problem and related issues. Let’ s take a look. Catalog Navigation:1. LED street lamp bead chip burn black. What are the causes of LED lamps? What causes the cause of black 5. What is going on with the black inside of the LED particles LED street light bead chip burn black is a chip penetration. For high power, voltage and current, there is a range. The main reason is that the heat dissipation is insufficient, the heat dissipation is not enough to cause the epoxy resin to turn black, the fluorescent powder is too fast, so the chip looks dark. There may be two reasons for chip electrodes: 1. Large current. For example, during testing, the instantaneous high voltage caused by the unstable of the power supply, or the large current caused by the accidental operation, the static electricity generally only produces black somewhere on the chip. 2. Oxidation. If the electrode is an aluminum electrode, it is easy to be oxidized and black. The gold electrode may also be vulcated and turned black.LED lamp beads are dark This is caused by poor heat dissipation of LED lamps. LED lights will generate a certain amount of heat when working. The greater the power generates, the more calories generate. You can touch the shell after lighting for a period of time. If the temperature is too high, you can take some measures appropriately, such as opening a few ventilation holes. If there is a heat sink, increase the area of \u200b\u200bthe heat sink) to reduce the temperature.LED lamp bead's light core is normal for black? Lighting beads are definitely black, indicating that the quality of the lamp beads is unstable. The lamp beads burned out and the current was too large. Replace the lamp beads in time to check whether the lamp plate and the radiator have heat -conducting glue and whether the connection is complete. Drive is broken. Replace the beads. If it is a lamp bead, change the lamp plate. The situation of the situation is severely delayed. chip's hacking, that is because the LED lamp lamps are poorly dissipated or the LED lamp bead super power is used to cause the LED collagen carbonization. , Increasing the heat dissipation effect, limit the flow resistance and reduce power can solve this problem. LED particles are black in the particles That is the heat dissipation of the LED light, which causes the LED light temperature to be too high, and the lamp beads have been burned out. The most important thing to pay attention to LED lights is heat dissipation. If the heat dissipation problem is done, the LED lights can be used for tens of thousands of hours and there will be no problem. Your lamp bead is dark, I think the LED is too high, causing the silicone burning on the lamp bead. The above is the answering answer to the question and related questions about the LED lamp bead black core LED lamp beads. I hope it will be useful to you [Responsible editor: beautiful lamp] |
