Turn off or flicker the lamp when we are doing something special is an annoying thing. Some lamps can be repaired and can be used again at a low cost. This will prevent extra costs. In this article, you will learn how to repair the lamp and you will be able to reuse them.
What are the common causes of lamp failure?
Lamps, regardless of their type (whether traditional, low -consumption or LED) may have problems after a while that disrupt their function. Finding the main cause of these failures can be the first step to their successful repair. The reasons that cause the lamps to break down are:
1. Power voltage fluctuations
One of the main reasons for the lamp failure is voltage fluctuations in the power grid. When the voltage is too high or reduced, the internal components of the lamp are under pressure. In LED lamps, this can burn the internal driver. In incandescent lamps, voltage fluctuations cause the tungsten strand to be too hot and eventually cut.
If a few lamps in your home have problems at the same time, it is probably a problem with electricity fluctuations. The use of voltage shielding can prevent this type of failure.
2. Excess heat
Lamps require proper ventilation for proper operation. The accumulation of heat around the lamp, especially in LED lamps, can damage its electronic circuits. Unlike incandescent lamps that better tolerate heat, LEDs are very sensitive to heat. Symptoms of heat -induced failure are:
- Reduce the light intensity of the lamp
- Sudden shutdown after a few minutes is on
- Change the color of the light to yellow or blue
1. The faint fittings or loosening of the lamp
Sometimes the problem is not the lamp itself, but it is from the head or socket. If the lamp is not properly placed or the internal fittings are loose, the power current will not be completely transmitted and the lamp begins to fold or turn off.
You can rotate the lamp slightly to find out this problem; If it is turned on or the situation changes, the problem is of connections. Also, checking the scalp for burns or melting can also give you important clues.
1. Low quality parts
You may be tempted to buy cheap lamps, but this choice can cost more in the long run. Bowler lamps are usually made from weak raw materials and non -standard technologies that do not have good durability and performance. Signs of low -quality lamps:
- Non -uniform light or flickering from the very first days
- Hot -over -the -body hot
- Shutting down the lamp after a short time working
1. Moisture and dust penetration
Wet environments such as a bath or kitchen can penetrate the lamp’s interior. The dust can also disrupt the electrical connections and cause the short circuit or overheating. To prevent this problem, you can use moisture -resistant lamps in humid spaces and periodically clean the dust around the screws and sockets.
Tools required to repair lamps at home
Home lamp repair may seem a challenge at first glance, but with the right tools and how to use them, you can solve many common problems. The tools needed to repair the lamp include:
- Hove (40 to 60 watts) to solder
- Solder wire to connect electronic components to the board
- Multimeter to measure voltage, current and resistance
- Tongs or pens to keep and move small parts
- LED chip strip to replace light diodes
- Solder oil to facilitate the soldering process
- Heater or industrial hairdryer to separate sensitive parts without damaging the range
- Insulation gloves and safety glasses for personal protection against electric shock and preventing possible damage
- Different screws to open and close the lamp frame and access the internal parts
How to troubleshoot the burnt lamp
When your lamp is turned off suddenly and no longer turned on, you may feel you have to go for replacement, but in many cases, this problem can be resolved with a simple and simple troubleshooting. You need to do the following to troubleshoot the burnt lamps:
Step One: Check the power source
First of all, you need to make sure that the problem is not the lamp itself. One of the first things to consider is the power source. Many of the problems with the lamps are caused by a power outage or voltage fluctuations. To do this:
- Check if other electrical devices work in the same location. If other devices are off, it is probably a problem with the power source.
- If you are using low -powered lamps or LEDs, check if the socket or the power socket works properly.
Step Two: Check the Lamp Connections
Incorrect or loose fittings of the lamp can be the main cause of the lamp shutdown. To examine this subject should:
- Remove the lamp from the screw.
- Check the scalp for any damage or corrosion.
- If you have no problems in the head, reinstall the lamp and make sure it is properly in the head.
- Sometimes, you just have to rotate the lamp slightly to make the connection.
Step Three: Check the fuse or internal driver of the lamp
In LED and low -use lamps, fuses or internal drivers may burn and prevent the lamp from turning on. You must do the following to check this section:
- Open the lamp and carefully check the internal circuit.
- You should replace it if you see a driver’s injury or burns.
- If you are using internal driver lamps, remember that you should use similar parts to replace to fix the problem completely.
Step Four: Testing lamp with multimeter
One of the most accurate ways to diagnose the burnt lamp problem is to use multimeters. You can measure the resistance of the lamp using a multimeter. If the lamp is burnt, its resistance will increase dramatically or change.
How to fix the problem with the LED lamp?
LED lamps are one of the common problems that many people face when using these types of lamps. This problem can be for a variety of reasons, including voltage fluctuations, driver failure, or even problems with the lamp circuit. The reasons for the lamps of the LED lamps and the solutions are:
1. Checking the voltage fluctuations
One of the main reasons for lding LED lamps is voltage fluctuations. Sudden changes in power voltage can cause problems with the performance of LED lamps. These fluctuations can be due to internal problems in the building’s electrical system or problems with power supply from the public network. You can fix this problem:
- Use the power protector: One of the easiest ways to deal with voltage fluctuations is to use a power shield. These devices can control power fluctuations and prevent damage to LED lamps.
- Check the cables and connections: Loose joints or damaged cables can lead to electrical fluctuations. A careful examination of wiring and ensuring the health of the cables can help a great deal.
2. Checking the LED lamp driver
Drivers of LED lamps are responsible for converting the voltage and current to the frequency and intensity for the lamps. Driver failure can make the lamps flicker. Poor or broken drivers may cause problems for the lamp uniformity. To solve this problem should:
- Replace the drivers: If the problem is from the lamp driver, it is best to replace it with the new driver. Standard drivers have specific specifications for each type of LED lamp they must match.
- Do test with another driver: If you have a doubt that the problem is from the driver, you can test the lamp with another driver. This can help to accurately identify the problem.
1. Use appropriate transformer
In LED lamps that require a transformer, the use of incorrect transformer can make the lamp flicker. Transformers that do not produce proper voltage may cause irregular performance of the lamps. You can fix this problem:
- Use quality transformer: Make sure you use transformers that are compatible with your LED lamps. Checking the technical specifications of the lamp and the transformer can help you make a better choice.
- Check the capacity of the transformer: Sometimes the transformer capacity is less than the lamp requirement, which can cause problems. Investigating the capacity of the transformer and its compliance with the lamp needs can be a good solution.
1. Check the quality of the LED lamp
In many cases, lodging LED lamps is due to their poor quality lamps. Bowler lamps usually have poor circuits and inappropriate internal components that cause this problem.
