Constant lighting problems that occur at 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 expensive service for today. Therefore, in order to avoid certain 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 in operation, however, of course, there comes a time when it fails and requires timely repair. Therefore, it is definitely necessary to have the skills to correctly identify malfunctions, eliminate dysfunctions, and also restore the previous condition of the equipment. It should be noted that the basic LED spotlights do not provide for the replacement of light sources with another with excellent power.
The main causes of a spotlight malfunction
Often, the cause of the breakdown of the LED lamp is the overheating of the matrix, as a result of which all fuses are burned. Indirect causes that lead to dysfunction of the searchlight are considered to be:
- short circuit;
- overvoltage;
- Incorrect network connection
- overcurrent connection;
- non-compliance with the device connection diagram.
Before you start repairing the LED spotlight yourself, it is recommended that you carefully consider the formation of a matrix defect. Typically, a matrix is a device that works with crystals. Basically, there are dozens of them, but with a malfunction of 5-7 crystals, the device continues to function in the previous 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 searchlight conductors.
Often the malfunctioning of LED sources occurs due to malfunctions of drivers supplying the crystal surface of the spotlight. In the event that the device has become unusable before the expiration of the warranty period, they should provide assistance or replace them at the place where the device was purchased. Otherwise, you will have to think about how to make an LED spotlight yourself, or pay for repairs to specialists.
DIY repair LED spotlight features
Before proceeding with the repair, it is recommended to prepare the necessary set of tools and clarify the cause of the malfunction of the device. Any damage must be repaired properly in order to avoid another problem.
The main candidates for repairs are LED spotlights made in China, the average power of which is 10 watts. It is on this example that we can consider the solution to the problem associated with breakdown.
Repair procedure
So, the algorithm of actions will be as follows:
- First you need to unfasten the cover of the device to ensure that you can work with the internal mechanism.
- Then you need to remove the glass shield and the light diffuser.
- Then you should unsolder the LED source from the matrix.
- And finally, solder it to a new, already working crystal panel.
After carrying out the above steps, each bolt should be securely fastened and the spotlight should be checked with a multimeter. If the proverbial will show the working position, then the lantern can be mounted in its original place and enjoy its work. It is important to note that the polarity must be observed when installing a new matrix.
In the same way, you can repair a 220-volt LED spotlight with your own hands. Beginners should also be aware that when troubleshooting is complete, proceed in the reverse order. By the way, it is possible to identify problems during operation by the following signs:
- light flashing;
- violation of isolation;
- wire deformation;
- change of LED shades;
- dull burning.
The principle of operation of the LED spotlight
Often during a breakdown, there is a desire to repair the LED spotlight yourself. However, first you need to know the nuances of the device. Typically, the operation of the device is due to the joint functioning of certain installed systems - optics, power supply, drivers and heat sink elements. Inside the case there are LEDs and small electronic elements. The voltage to the LED element converts the current into light rays. As a result, a spotlight glows.
Finally
Having convinced of the operability of the device and the normal functioning of all its elements, it can be improved with your own hands. A 12 volt LED spotlight, for example, does not have a rectifier and stabilizer. Therefore, repairing on their own, such devices are not so difficult to install. To do this, it is enough to connect pairs of LED sources in a sequential action, which are turned on in the opposite way. Then apply a ballast capacitor to them. As you can see, repairing LED spotlights is not such a difficult task, if you know the basics of the theory of their arrangement.
