The tips mentioned will help you to narrow down the faults and, in the best case, to solve them.A short two to three years ago, LEDs were considered unfit for many lighting applications. In this article you got a good overview of common LED problems. There are many reasons for defective LED luminaires and broken LED lamps. If you find strong voltage fluctuations as a cause for your LED defects, you should definitely consult an electrician or the energy supplier. On the other hand, power fluctuations can be caused by large industrial machines in the neighbourhood. Fluctuations in current often occur in older or incorrectly dimensioned electrical installations. When these devices are switched on, strong voltage fluctuations occur, causing the light in the home to flicker briefly or certain appliances to switch off briefly. Power fluctuations can be caused by large electrical devices such as boilers or fan heaters. Here the effort for disconnecting and connecting is naturally greater. Permanently installed lights can also be connected to a different circuit if problems occur. If the light source works properly here, you have already limited the error to the original place of use and can further investigate there. In the best case, this lamp should be connected to another circuit. If your LED light source does not work properly, you can remove it from the lamp and try it out in another lamp with the same socket. For your own safety you should hire an electrician to solve the problem. Troubleshooting and modifications may only be carried out by qualified persons. If the LED strip is still dark, the controller is probably broken.ДangerAll changes to the electrical installation pose a risk to life. To avoid a defect of the power supply, you may be able to use another power supply with the same voltage (usually 12V) for testing. Most controllers are supplied via a plug-in power supply. If no error can be detected here, the most likely cause is the LED Stripe Controller. There must be a solid electrical connection to the contact surfaces of the strip. Especially the connector between cable and LED strip has to be checked, because this connector is very sensitive. You should check the connection from the controller to the LED strip. On the one hand this can be due to the wiring. This is usually the cause of a defect.ДЄ broken LED strip usually doesnвЂ™t glow at all. Most LED strips have a controller with a remote control. Even if individual LEDs fail here, this is hardly noticeable, because the majority of the LEDs still glow. LED Stripes have a variety of LEDs, which are all connected in parallel on most stripes. If your LED strip doesnвЂ™t work anymore, itвЂ™s rarely the LED Stripe itself.

All/several LEDs defective? вЂ“ This is what you can do in case of a defect of fixed LEDs.

Only one of many LEDs defective? вЂ“ No problem.

Then it is recommended to replace them with a lamp from a brand manufacturer. In the second case you should check if you have used cheap no-name lamps so far. Your LED lamps are constantly breaking down? You replace them and after a short time they are defective again? You should first check whether your LED lamps break down due to an external influence or burn out for no reason. This way you can analyze your own LED defects more precisely and find out whatвЂ™s wrong. Some errors occurred however frequently, which are described in detail in the following sections. Of course I canвЂ™t judge every defect from a distance. I occasionally receive questions from readers why their LED light sources have broken down in this or that situation.

Unsuitable transformer for low voltage lamps.

Very often external factors are the cause. The error does not necessarily have to come from the LED lamp itself. One reason for this could be that the unknown manufacturers from the Far East use cheaper components and skip certain tests for light duration and switching resistance. According to that no-name LED lamps often break already after a short time rather than the lamps of brand manufacturers.

Defects occur much more frequently in the power unit or LED driver.ДЄccording to my own observations and the messages of many readers a certain trend can be recognized. Due to the relatively complex structure of an LED light, there are many sources of error. On the one hand, this can be due to the lamp itself. Nevertheless, LED lamps can also break down.

Current LED light sources and luminaires are very durable and normally last between 15,000 and 50,000 hours.
