Abstract:

LED strip compared to traditional lighting, or a new product under development, so many consumers do not know much about how to install LED strip,

so what are the considerations in the installation and use of LED strips?

In the installation, be sure to follow the instructions, use the correct method to install, if excessive distortion,

or the use of incorrect installation methods is prone to damage to the strip.

At the same time, the LED strip should be a high-temperature, short-circuit-proof, if not waterproof strip, but also pay attention to moisture.

A, LED strip installation precautions

1, the power supply connection method: LED strip lights are generally DC 12V voltage, so you need to use a switching power supply,

the size of the power supply according to the power of the LED strip lights and connection length to determine.

If you do not want to use a power supply to control each LED strip, you can buy a relatively large power switching power supply to do the total power supply,

and then all the LED strip input power all in parallel (wire size is not enough to extend), unified by the total switching power supply.

The advantage of this is to centralize control, the inconvenience is not to achieve the effect of individual LED strip lighting and switch control,

which can be measured in their own specific way.

2, each meter has a “scissors” mark, can only be cut in the mark, cut the wrong or cut off will lead to a meter not light!

It is best to look carefully at the location of the mark before, according to the middle of the place not connected to cut off.

3, pay attention to the LED strip connection distance: in general, the 3528 series of LED strips,the longest connection distance of 20 meters, 5050 series of LED strip, the longest connection distance of 15 meters.

If beyond this connection distance, the LED strip is easy to heat up, the use of the process will affect the service life of the LED strip.

Therefore, the installation must be installed in accordance with the requirements of the manufacturer, do not let the LED strip overload operation.

4, each strip must be equipped with a special plug (a plug with a transformer), when connected must be removed from the transparent plastic cover,

connected to the test light, and then cover. Do not connect directly with the cover, so easy to short circuit!

5, outdoor installation: outdoor installation will be subject to wind and rain, if the 3M adhesive fixed words,

time will cause 3M adhesive to reduce the adhesion of the LED strip off, so the outdoor installation is often used slot fixed way,

the need to cut and connect the place, the same method and indoor installation, just need to be equipped with an additional waterproof adhesive

to consolidate the waterproof effect of the connection point.

6, indoor installation: LED strip for indoor decoration, because it does not have to withstand the wind and rain, so the installation is very simple.

To ordinary LED strip, for example, each LED strip has a self-adhesive 3M double-sided tape on the back, you can directly tear off the 3M double-sided tape surface stickers,

and then the strip is fixed in the place where it needs to be installed, and press the flat by hand. As for some places need to turn the corner or long how to do?

Very simple, LED a strip is a group of 3 LEDs as a series-parallel way to form a circuit structure, every 3 LEDs that can be cut off for individual use.

7, the controller connection: LED running strip and RGB full-color strip need to use the controller to achieve the changing effect, and each controller control distance is different,

in general, the simple controller control distance of 10 to 15 meters, the remote controller control distance of 15 to 20 meters, the longest can be controlled to 30 meters distance.

If the LED strip is connected to a long-distance, and the controller can not control that long strip, then you need to use a power amplifier to tap.

8, the light strip installation, generally placed in the light slot, swings straight on it, you can also use a thin rope or thin wire fixed.

For external or vertical installation, you need to configure another “card” and “tail plug”.

It is best to play waterproof glass glue in the tail plug and plug after installation so that the waterproof performance is better.

B, the LED strip in the maintenance knowledge1, anti-static

Because led is electrostatic-sensitive components if, in the maintenance of led strip without good anti-static measures, it will burn led,

resulting in waste. Here you need to pay attention to the soldering iron must use an anti-static soldering iron,

while maintenance personnel must also do a good job of anti-static measures (such as wearing static rings and anti-static gloves, etc.)

2, continuous high temperature

The two important components of the led strip led and FPC, are not sustainable high-temperature products.

FPC if the sustained high temperature or more than its withstand temperature, it will make the FPC cover film blistering, directly causing the led strip scrapped.

At the same time, led can not be sustained high-temperature resistance, in the high temperature for a long time,

its chip will be burned by high temperature. Therefore, the maintenance of led strip soldering iron used must be used to control the temperature of the iron,

the temperature is limited to a range, prohibit casual changes and settings.

In addition, even so, you need to pay attention to the maintenance of the iron do not stay

in the led feet for more than 10 seconds, if more than this time, it is likely to burn led chips.

3, short circuit

Many led strip bad, because there is a short circuit at the foot position before the repair must identify the real cause of the bad.

Otherwise, after the rash replacement of bad led, again when the power will continue to cause the led chip is short-circuited current breakdown.

Therefore, before replacing the new led, one must first find out the real cause of the bad, the right medicine to get twice the result with half the effort.
