Regular lighting problems that occur in the home require self-troubleshooting. And it is easy to agree that the systematic call of a specialist to repair an LED device is a rather costly service for today. Therefore, in order to avoid some discomfort, it is recommended to repair the LED spotlight with your own hands.
A modern LED spotlight is considered to be a popular and quite popular device that is used to illuminate the local area. Such a lighting tool is very convenient to use, however, of course, there comes a time when it fails and requires timely repair. Therefore, it is definitely necessary to have the skills of competently identifying faults, eliminating dysfunction, as well as restoring the previous state of the equipment. It should be noted that the basic LED floodlights do not provide for the replacement of light sources with another with excellent power.
Main causes of failurespotlights
Often the reason for the breakdown of the LED flashlight is overheating of the matrix, resulting in the burning of all fuses. Indirect causes that lead to dysfunction of the spotlight are considered to be:
- short circuit;
- overvoltage;
- wrong network connection;
- overcurrent connection;
- non-compliance with the device connection diagram.
Before you start repairing the LED spotlight with your own hands, it is recommended to thoroughly consider the formation of a matrix defect. As a rule, a matrix is a device that works with the help of crystals. Basically there are dozens of them, but if 5-7 crystals fail, the device continues to function in the same mode. Only complete combustion of the matrix requires intervention. But according to experts, in such situations it is desirable to make a complete replacement of the matrix. It should be noted that during repair work it is strongly recommended to insulate the conductors of the spotlight.
Often, the failure of LED sources occurs due to malfunctions of the drivers that feed the crystal surface of the spotlight. In the event that the device has become unusable before the expiration of the warranty period, then the place where the device was purchased should provide assistance or replace it. Otherwise, you will have to think about how to make an LED spotlight with your own hands, or pay for repairs.specialists.
Features of do-it-yourself LED spotlight repair
Before proceeding with the repair, it is recommended to prepare the necessary set of tools and clarify the cause of the device malfunction. Any breakdown must be properly repaired to avoid the problem from occurring again.
The main contenders for repairs are LED spotlights made in China, with an average power of 10 watts. It is on this example that we can consider the solution to the problem associated with a breakdown.
Algorithm of actions during repair
So, the algorithm of actions will be as follows:
- First, you need to unfasten the cover of the instrument case to allow yourself to work with the internal mechanism.
- Then you need to remove the glass protection and light diffuser.
- After that, unsolder the LED source from the matrix.
- And finally, solder it to a new, already working crystal panel.
After carrying out the above steps, securely fasten each bolt and check the spotlight with a multimeter. If the dialing shows the working position, then the lamp can be mounted in its original place and enjoy its work. It is important to note that polarity must be observed when installing a new matrix.
Similarly, you cando-it-yourself repair of a 220 volt LED spotlight. Beginners should also be aware that upon completion of the troubleshooting, it is necessary to proceed in reverse order. By the way, it is possible to identify problems during operation by the following signs:
- light bulb flashing;
- isolation breach;
- wire deformation;
- changing LED shades;
- dim burning.
The working principle of LED spotlight
Often, during a breakdown, there is a desire to independently repair the LED spotlight with your own hands. However, first you need to know the nuances of the device. As a rule, the operation of the device is carried out due to the joint functioning of certain installed systems - optics, power supply, drivers and heat sinks. Inside the case are LEDs and small electronic elements. The voltage to the LED element converts the current into light beams. As a result, the spotlight glows.
In closing
After making sure that the device is working and that all its elements are functioning properly, you can improve it with your own hands. A 12 volt LED spotlight, for example, does not have a rectifier and stabilizer. Therefore, repairing it yourself, it is not so difficult to install such devices. To do this, it is enough to connect pairs of LED sources in series, which are switched on in the opposite way. Then apply ballast to themcapacitor. As you can see, repairing LED spotlights is not such a difficult task if you know the basic theory of their design.
