LED light is not on the repair method
1. First, we can check whether the led bulb is not on due to part of the power supply of the power supply system. If so, we can check the power supply route. If everything is normal, the led bulb is connected. Come up here. The indicator value above is lit.
2. Below, in addition to clearing the power supply, if it is still not bright, we must also check the positive and negative feet of the led bulbs. Let's see if the led bulbs used by everyone are properly connected in actual operation., If there is any wrong operation. If the light bulb is not lit, the led light bulb can be welded again-it can be handled normally.
3. Check the current flow of the led light bulb and inquire about the current flow on both sides of the led light bulb. Whether the whole meter of the led light belt is not on or not can be divided into two situations. One is that all the strips will not light up, while the other is that only one section will not light up. The former factor may be caused by the power plug falling off and turning off the power supply. In other words, the power socket of the connector is broken. It is good to check whether the power plug is firmly plugged or not. Exceeding the amount of current in the work of the led bulb, if so, this kind of situation is also very easy to cause the led bulb to not shine, the solution is to select the appropriate constant current power supply, as far as possible can not buy some cheap power supply. In this way, it can be avoided that the light bulb does not light up due to the penetration of the general led light bulb due to the power supply current.
4. The product quality problem of ledLED lamp beads itself can also cause ledLED lamp beads not to turn on. As some LedLED lamp beads integrated ic have power supply, this kind of situation is also very easy to cause ledLED lamp beads to die after being applied for a period of time. The solution is to avoid the inventory of LED lamp beads under wet and cold conditions for a long time as possible, so as to avoid the LED lamp beads not turning on due to leakage caused by internal chip moisture.
5. The short circuit of the led bulb may also cause the led bulb to be off. This situation may be caused by the virtual welding of some small companies in the production process of the led bulb, and the open circuit caused by the extrusion of the gold wire by the thermal expansion and cold contraction colloid of the led bulb. The other kind of problem is relatively common and may lead to many kinds of problems;
1. Broken plate of lamp strip
2. Resistance deselding
3. The resistor is burnt out, the chip is burnt out and the LED lamp strip is lit for a long time, causing overheating. There is also a possibility that the led lamp is burnt out due to voltage. Due to excessive current or voltage, the resistor is broken down and the resistor is seriously damaged. Therefore, the whole meter of the lamp is not lit. These are very obvious. Generally, there will be traces of burning out. You can check them carefully.
