Hello everyone, I am a beautiful lanterns. Today, let ’s introduce the question of how much power is the power of LED lamp beads 300 lamp beads. The following is the summary of this problem and related issues. Let’ s take a look. Catalog of the article:1. How to change LED lamp beads 2. How to change LED lamp beads 300x300 3, LED lamp bead test instrument evaluation 4. How to replace LED lamp beads in the living room lamp LED lamp bead replacement operation steps are as follows: First of all, after 25-30 seconds of the power-on switch, the constant temperature heating table can be warmed to 250 ± 10 ° C. The light source lamp will not damage the LED lamp beads Then, the maintenance site of the LED lamp tablet is about 10 seconds of heating platform. Take off the bad lamp beads one by one, and then replace the prepared lamp beads (you can remove the lamp beads from some abandoned LED light sources in advance to turn the lamp beads into Baodang as a spare lamp bead) one by one. When the lamp beads, pay attention to the+-positive and negative electrode direction of LED lamp beads, and the lamps are not bright. Among them, the skills to avoid similar problems are compared to how the adjacent lamp beads are arranged. Finally, after changing the lamp beads, remove the maintenance site and remove the heating platform for 3-5 seconds. After the LED aluminum substrate or glass fiber plate is cooled and cools down, the tin paste solidified and automatically welded the lamp bead. Precautions 1. The heating platform and the parts of the part of the contact during the maintenance process are high temperature. Do not touch it to avoid burns. Pay attention to the operation of operation. 3. Double -sided available on the heating table can be selected according to the actual situation of the LED lamp board.How to change the LED lamp bead 300x300 is the most convenient to have hot air guns. It is not called to use the welding table, put the board on the welding platform, adjust the temperature of 280 degrees, and gently move it with a mule to win the bad. By the way, you can put the good lamp beads.LED lamp bead test instrument evaluation 1. If there is a multimeter in the home, then the multimeter is convenient to detect LED patch lamp beads. test tools. We can test the lamp beads by using the diode gears of the universal meter. How to use the red table pens, and the black table pens are connected to the negative pole. If there is a bee, the LED patch is broken when it is connected. Therefore, using a multimeter to test low -voltage LED patch lamp beads is a commonly used method for judging LED lamp beads. Second, if LED lamp beads are often developed or tested, you can buy a LED test pen. This LED lamp bead test pen can be more intuitive testing and lighting up LED lamp beads to determine the quality of LED, and the price is not expensive. You can buy one in tens of yuan. 3, LED lamp bead tester, is also a relatively easy -going LED patch lamp bead detection tool. How to replace the LED lamp beads in the living room lamp The living room light is broken. 2. Prepare the new LED lamp, unscrew the lampshade, and twist the test lamp with a screwdriver. 3.

The installation holes of the lights are aligned with the screws on the ceiling, and the card is tightened in place to ensure that the lights are firmly installed. 5. Finally, insert the wires on the top into the wire interface of the lights, tighten it, and install the lampshade back. The above is the answer to the question of how much power and related issues of the LED lamp beads 300 lamp beads, I hope it will be useful to you [Responsible editor: beautiful lamp] |
