Hello everyone, I am a beautiful lantern. Today, let ’s introduce the problem of the black black lamp beads LED lamp beads. The following is the summary of this problem and related issues. Let’ s take a look. Catalog of the article: 1. What is the cause of the dark inside of the lamp on the LED module? 2. What is going on with LED lamp beads? What 5. The LED lamp does not light up the black beads and turn black What is the cause of the black beads on the lamp on the LED module, which causes the darkness of the area of \u200b\u200bthe chip area, it is because the LED lamp lamps are poorly dissipated or the LED lamp bead is super power The use of LED collagen carbonized hair black, replace LED lamp beads, improve the heat dissipation effect, and reduce the flow resistance and reduce power to solve this problem.
LED lamp beads are dark This is caused by poor heat dissipation of LED lights. 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 is normal?
Lighting beads are black, it is definitely not normal, 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.
Black lamp beads Black LED lamp LED display screen uses red, green, and blue -haired light to express images. For the electronic display, it is black , then his办法是不发光(因为自然界中没有黑色的光)所以所有的电子显示屏表面被设计成黑色的。 For example, TVs, plasma displays, computer display screens and other surfaces are black. LED light does not light up the lamp beads black That is the heat dissipation of the LED light, which causes the LED light to be too high, and the lamp beads have 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. Without the power supply, it was directly connected to 220V to burn the lamp beads. The above is the answering answer to the problem and related issues of LED dumb black beads LED lamp beads. I hope it will be useful to you [Responsible editor: beautiful lamp] |
