Hello everyone, I am a dream. Today, let ’s introduce the problem of circular LED lamp bead repair. The following is a dream of summarizing this problem and related issues. Let’ s take a look. Catalog of the article: 1. How to repair the LED ring lamp. 2. How to repair the disk LED lights. 3. How to repair the LED circular lamp beads. How to repair the lamp beads when it is not lit LED ring lamp is broken.2. Replace the new driver power. 3. Replace the new LED light. The method of trying to turn the LED lights on the fastest and most secure way is: to directly replace the new LED light, which saves time and effort. The flames that were illuminated in the night before the night were flames. Nowadays, the tools that people use for lighting are mostly electric lights, and they are still various lights. They are white, yellow, and red. In short, it is colorful. The LED light is a more light light, because it has a good lighting effect and is green and environmentally friendly. However, after a long period of use, it is also easy to occur, and it often occurs.
Disc LED light is broken 1, using a multimeter (the output current of the multimeter must be large) Diode gear to measure whether the LED lamp bead is glowing and a single measurement. Use the lamp bead test instrument to measure a piece of lamp beads. Take a look at that light (good eye protection). Do not buy it too expensive to buy the lamp bead tester. It can be used. Generally, we ca n’t use it a few times. 2, use the heating board (cheap) or preheating platform (more factories), remove lamp beads. Generally set at about 200 ° C. The temperature with lead will be lower. 3, pay attention to the voltage of the lamp beads when changing the lamp beads. When measured with a lamp bead tester, we measured the voltage of a string of lamp beads. Except for the number of lamp beads is the voltage of the lamp beads. Then select the right lamp bead to replace. If the lamp beads are broken, some people will be able to use this light bead directly, so it can also be used, but it is not recommended to do this. This will reduce the service life of LED lights.
LED circular lamp beads are bad. How to repair LED lamp generally do not repair it. When you really want to repair it, you only need to connect the joints on both sides of the lamp bead. LED lamp beads are not broken. How to repair 1. Before the LED light is turned on, measure the voltage of the power supply, and the current flowing through the LED, then remove it, check all the key parts one by one , LED lamp beads, the broken lamp beads replace. 3, the cause of the damage to the LED lamp beads, if the current is over, reduce the driving current immediately. Check whether there is a failure of the driver, and you must also find out the reasons. 4. If the LED power is damaged, buy the power supply of the same parameters such as voltage and current for replacement. /5. If the LED light is more damaged, and the damaged LED patch lamp is concentrated in the same area, the damaged section can be cut off and welded.
LED lamp beads are not lit, how to repair 1, first remove the lampshade of the LED lamp, then connect the power, observe the position where the LED light is not bright, and mark it in advance. 2. After the mark is made, disconnect the power (pay attention to safety), remove the non -bright lamp beads with pliers, but be careful not to scratch the LED circuit board. 3. Prepare 4 to 5cm wires in advance (then use the wire as a lamp bead) to heat it on the electric iron. 4. At this time, welded the two ends of the connected wires to the two contacts of the electrode iron, and then the brightness of the LED could be restored to the previous level. Did you learn? The lamp beads used on the top are series, so when one of the lamps or several lamp beads in the LED lamp is not bright, the overall resistance of the bulb is very large, so it can only emit weak light after connecting. The editor of Tiancheng has answered the maintenance question and related issues of the circular LED lamp beads. I hope it will be useful to you [Editor in charge: a dream] |
