Hello everyone, I am Xiaobian Rong Sister today, let ’s introduce the LED lamp to the whole lamp bead LED lamp beads, which need to be replaced with a new question. The following is the summary of this issue and related issues. Let's take a look together. Catalog of the article:1. How to change the lamp beads of LED waterproof lamp 2. Is the lamp bead of LED lamps broken one? 3, LED lamp bead replacement skills 4. How to change lamp beads with three -color LED light 5, LED lamp beads disassemble the new method LED waterproof lamp to change the lamp beads First of all, we remove the shell of the LED lamp, and you can see the lamp beadboard. Lighting beads are inserted and patch type. If the lamp beads of LED lamps are inserted , we use electricity to heat the damaged lamp beads and remove it. The lamp beads are welded and fixed. If the lamp beads belong to the patch, we use the hot wind of the hair dryer to blow the damaged lamp beads. Essence LED lamp lamp beads are broken? Do you need to change all?LED lamp bar is broken. Everyone changes the whole bar or the lamp bead is changed. The patch lamp beads carefully look at a small black spots on the top, cut it with an oblique pliers, and then connect it at the weld welding gap so that it can be used. The LED is generally durable. Under normal circumstances, at least 35 years depending on the use time and conditions, the use time is longer. Generally, there are more than a dozen to dozens of composition of a certain length. If a group of current limit resistance is damaged It will lead to a set of not bright. If there are bad in the middle, you can cut off the new docking of the group from the cut line LED lamp bead replacement skillsLED lamp beads are divided into patch type and inserting type, The new ceiling lamp or LED bulb is used in pieces. If it is a single light, such as an electrical indicator, and the older ceiling lamp, they are used to insert a foot. Put -of -footed lamp beads are installed by welding. When installing, first use the electric iron to heat the old lamp beads. Put the new lamp beads and welded with tin strips. The lamp beads are stuck through special glue. The hot air fans are used during installation. If not, use the hottest iron or hair dryer to heat the back of the old lamp beads to easily remove it. Put the new lamp beads and wait for cooling. No matter what kind of lamp beads, you must pay attention to two points when installing: 1, the lamp beads need to distinguish the positive and negative electrodes, whether it is inserted or patch type, one end with a small hole is the negative electrode. There will be a positive and negative mark on the lamp board. Keep the beads the same as the polarity of the lamp beads during installation. 2. The use of electric iron or hot fans will make the lamp beads hot, so disassembling lamp beads, be sure to use mules. The replacement of the whole row of lamp beads: The whole row of lamp beads are usually installed on the end of the electric lamp.LED lamp modified by the sunlight, the lamp board is sucking on the electric light base through the magnet, and it can be suck directly. How to change the lamp beads for three -color LED lamp First of all, we remove the shell of the LED light and see the lamp bead plate. The lamp beads are inserted and patch. If the lamp beads of the LED lamp are inserted, we use electricity to heat the damaged lamp beads and remove it, and then welded the new lamp beads with tin strips. If the lamp beads belong to the patch, we use the hot wind of the hair dryer to blow the damaged lamp beads. The glue sticky of the lamp beads can be torn off, and then the new lamp bead is posted. LED lamp beads disassemble the new method 1, the disassembly and replacement method of general aluminum substrate LED lamp beads needs to be determined according to different circumstances. The plate will also be in the bright place, so it will be easier to replace. First, use the soldering iron to heat the two welding joints to remove the bad lamp beads, and then use the soldering iron to flatten two pads. Do not remain too much welded so that the lamp beads can be closely attached to the aluminum base plate. Then put the new lamp beads in the original positive and negative electrode in the original place, then order a little welding at the pins, and hold the lamp bead with your fingers to weld it. In addition, it is best to apply some heat -conducting silicon grease on the circular pad in the middle to reduce its thermal resistance. 2. For watch stickers such as 5730, the disassembly method will look more troublesome. You can remove the hot air gun and the electric soldering iron down, as long as it does not destroy the aluminum substrate. Then use the soldering iron to remove the excessive welding, leaving only a thin layer, and then click the welding to put the lamp beads in the original direction. The next step of welding must be started from the back, because the front pad is too hidden, the soldering iron will not be able to start, and it will easily scorch the gels of the lamp with a hot air gun. Find the position of the lamp beads on the back of the aluminum substrate, and then heat it with a large tile or hot air gun until the front weld melts the lamp beads to welded. The above is the editor of Tiancheng who has broken one of the LED lights to change the lamp beads. |
