LED strips and the causes of their burnout

Content of

Recently LED products are very popular in the domestic marketdemand. The highest demand for this is using LED strips. Despite the abundance of offers on the market, the problem associated with the fact that the LED tape has ceased to burn, is relevant for many users.

Causes of partial burnout of the LED strip

Unfortunately, tough competition does not always provoke an increase in product quality. Therefore many sellers traditionally quite successfully increase sales volumes by lowering prices. Buyers, not being specialists in the field of LED technology, buy cheap sellers on the advice of sellers, install them and enjoy the result. True, this joy lasts a very short time. Very soon the question arises before the users, why the LED ribbon burned out. But even in the event that the ribbon for the joy of the customer continues to function, after some time it will lose the luminescence brightness by about 30-40% of the initial values. And the user will again be disappointed.

In principle, the life of LED strips is long enough. But only in the case when it comes to high-quality lighting equipment made with full compliance with the technological process. Unfortunately, about 99% of LED products are produced in China. Of course, in China they produce high-quality LED ribbons, but it is unlikely to find them for 100 rubles with a small amount.

Many consumers of LED products do not think about whether a LED tape with such a low market value can burn out. As a result, they become the owners of a product with a minimum content of copper or even on foil, with poor-quality diodes and resistors and a drop-off adhesive layer that was manufactured by hard-working inhabitants of the Middle Kingdom in some basement shop.

Consequences of savings on the purchase of LED strips

If you made a choice in favor of cheap and knowingly low-quality LED products, you should not be surprised by the fact that after a small amount of time, the LED tape stopped giving signs of life. Moreover, you should be prepared morally and to the following unpleasant surprises:

• a variety of glow;
• loss of brightness of luminescence;
• uneven glow from the beginning to the end of the tape;
• low quality glue.

In this case, all claims to the seller will be useless. At best, he will visit the Chinese quality, and at worst will simply refuse to talk.

Why LED stripes can burn out

However, the acquisition of a fairly expensive tape is not always a guarantee of a long work. Breakage can happen with expensive and potentially high-quality goods. And the problem is often not in the use of cheap components or factory marriage. Often the problem is connected with the fact that the ribbon chosen by the buyer does not match the technical conditions of the conditions in which it will be used.

So often do not take into account the current of the tape and the source of energy, from which it will work or do not comply with the thermal regime, installing LED tapes intended for indoor use on the street.
Often the reason that a part of the LED tape has burnt out or the equipment is completely out of order is due to an error in the installation. Often, users simply incorrectly install the LED strip. In particular, they do not provide it with reliable mechanical protection. As a result, even the most insignificant damage leads to the ingress of moisture or water into the device, and then individual sections or entire LED strips burn out.
Sometimes the cause of the failure of the tape LED equipment is the error made in the design of the wiring diagram. Since the majority of the LED strips are a chain consisting of parallel segments, the current at the ends of the entire chain is passed through all the individual sections, summed. And in the case when it comes to a sufficiently large segment, the total current can be rather large. This usually leads to the fact that the tracks of the tape are subjected to overheating, and therefore very quickly partially or completely out of order. To prevent such a problem, it is necessary to break long sections of the tape into smaller segments.

How to properly operate the LED tape to extend the life of its

If you do not want the LED lamp to burn out, you should follow a number of rules that will significantly increase the period of trouble-free operation of the LED equipment:
Do not connect in seriesLED strip, the length of which exceeds five meters. In this case, only parallel connection of segments is allowed. Otherwise, it is possible to avoid significant voltage drops and an increase in current on the tracks. And this in turn will cause the tape to cause serious damage, up to the failure of it.
Do not use tape LED equipment in environments where the ambient temperature exceeds + 40 ° C.
Do not allow moisture to enter the exposed tape.
Under no circumstances should LED tapes be immersed in water, even partially.

It is equally important and correctly to mount the LED strip. Correct installation in conjunction with proper operation will significantly increase the service life of LED strips.
Before proceeding with the installation of the equipment, it is strongly recommended that you turn it on and check the specified color. Unfortunately, practice shows that tapes from different parties can differ substantially in shade.
When connecting, pay close attention to the correct polarity. This is especially important if you do not want the LED strip to stop burning after a couple of months.
If the LED equipment is mounted on a metal or other conductive surface, it must be isolated. If this is not done, a short circuit will occur, which can lead to the most tragic consequences.
In no case should even the slightest damage to the tape track be allowed during installation. Cutting of tapes is allowed only between special areas for soldering. If you cut the equipment in other places, non-working segments will appear.

LED tapes often burn out because users connect them directly to household power supplies, which is completely unacceptable. The LED strip is designed to operate only from DC 12 volts or 24 volts.

The voltage is usually indicated on the entire length of the tape. A voltage switching power supply is required to convert the voltage. This device is responsible for converting the AC mains voltage of 220 V AC.in the direct current of the required value. The correct calculating current will help the online calculator.

Accordingly, when selecting a power supply unit, it is very important not only what DC voltage produces at the output, but also how much it can give out to the load. In order not to make a mistake with the choice, it is necessary to make careful calculations of the total amount of current consumed by the installed LED strips. And depending on the result obtained, choose the power supply.

LED tapes in recent years are very often used to decorate both the interior and exterior of buildings. And every consumer who makes a choice in favor of this equipment, is interested in ensuring that it has served, not delivering problems, for as long as possible. It is quite possible, the main thing is to purchase products only from a reliable manufacturer and not to make mistakes when installing and operating the equipment.
