The reason and maintenance of led Lamp not working
The common faults and maintenance of the led lamp are as follows: the solder joint of the LED lamp strip has the phenomenon of virtual welding, and the vibration in the transportation process causes the solder joint to fall off and the lamp belt is not bright. The quality of solder is not good, and the solder joint of LED lamp strip is easy to crack and fall off in the process of bending.
Lamp is not bright this fault generally has two reasons, one is the lamp aluminum substrate LED lamp T beads damage (LED lamp beads are connected in series, according to the law of physics, once a damage, the entire circuit will be interrupted), another reason is the lamp constant current drive power damage, resulting in lamp beads can not get the working voltage.
The phenomenon of virtual welding exists in the solder joint: this situation is generally caused by excessive vibration of the lamp in the process of transportation, and the protective measures are not achieved, and its solder joint falls off with the vibration, resulting in no light.
What are the maintenance methods? The reason why the LED energy-saving lamp is not lit needs to ensure that there is no problem with the installation of the power supply. You can reseat the other lights to see if they are bright. If this lamp is bright, you should eliminate the power failure and consider the problem of the LED energy-saving lamp.
What is the reason why the led light is not on? How to repair it? Let’s take a look.
The reasons why the LED is not bright are as follows: the packaging protection of the LED lamp strip is not perfect, which causes the lamp beads to be damaged by impact during transportation. The solder joint of the LED lamp strip has the phenomenon of virtual welding, and the vibration in the process of transportation will cause the solder joint to fall off and cause the lamp belt to be not bright. The solder content of LED lamp strip is small, and the solder joint is easy to fall off.
Bad switch contact: if the contact of the switch is not touched, it will cause the light to flicker. At this time, we can turn on the switch and touch it with our hands to see if there is any bad contact. If so, we can use a fine needle or toothpick, gently pick some up, and then plug it back in, and then we can solve it.
The possible reasons are as follows. The power supply system is unstable. A part in the power supply circuit for the LED lamp is damaged. The power switch that controls the LED lamp is not in contact with reality. Solution: restart the power supply system again to see if the LED light is normal. Send the lamp to the repair station to repair or replace the LED lamp.
How to fix the LED lamp if it is broken? There are two reasons why LED lights are not lit: first, the excessive leakage current of LED causes PN junction failure, so that LED lights are not lit, which generally does not affect the work of other LED lights; second, the internal connection leads of LED lights are disconnected, resulting in dead lights caused by no current passing through LED.
How to repair if the led light is not on
The common faults and maintenance of the led lamp are as follows: the solder joint of the LED lamp strip has the phenomenon of virtual welding, and the vibration in the transportation process causes the solder joint to fall off and the lamp belt is not bright. The quality of solder is not good, and the solder joint of LED lamp strip is easy to crack and fall off in the process of bending.
Therefore, if the LED light does not light up suddenly in use, it is recommended to cut off the power supply and carry out maintenance. Science Popularization of related knowledge: at present, the more common light sources of led lights are white light and yellow light, the lighting effect of white light is better, and yellow light is mostly used as an auxiliary light source.
The revision of the led lamp is as follows: first remove the lampshade and turn on the electricity to see which lights are not on. Mark it with a pen. After finding the unlit lamp beads, pull out the unlit lamp beads with pliers and be careful not to scratch the circuit board. Replace lamp beads with wires and prepare wire 4-5cm. Connect the soldering iron to the power and heat it.
If the LED light is off, here are some possible repair methods: replace the LED lamp beads: the burnout or aging of the LED lamp beads may cause the lamp not to shine, you can try to replace the new LED lamp beads. When replacing LED lamp beads, be sure to choose the correct specification and model, and pay attention to using the correct installation method.
What if the LED light is off? how to fix it if the LED light is broken?
The main results are as follows: 1. The common faults and maintenance of the led lamp are as follows: the solder joint of the LED lamp strip has the phenomenon of virtual welding, and the vibration in the transportation process causes the solder joint to fall off and the lamp belt is not bright. The quality of solder is not good, and the solder joint of LED lamp strip is easy to crack and fall off in the process of bending.
2. When the led lamp is off, the revision is as follows: first, remove the lampshade and turn on the electricity to see which lights are not on. Mark it with a pen. After finding the unlit lamp beads, pull out the unlit lamp beads with pliers and be careful not to scratch the circuit board. Replace lamp beads with wires and prepare wire 4-5cm. Connect the soldering iron to the power and heat it.
3. If the LED light is not lit, here are some possible maintenance methods: replace the LED lamp beads: LED lamp beads burn out or aging may cause the lamps and lanterns not to shine, you can try to replace the new LED lamp beads. When replacing LED lamp beads, be sure to choose the correct specification and model, and pay attention to using the correct installation method.
4. If the LED bulb is not lit, here are some of the easiest ways to fix it: check that the bulb is installed correctly: make sure the bulb rotates into place and inserts the lamp holder correctly. Replace the bulb: if the bulb is burnt out or damaged, you need to replace a new bulb.
