First, what is the LED light belt
The lamp belt refers to the LED lamp with a special processing technology to weld on the copper wire or banded flexible circuit board, and then connected to the power supply light; It gets its name because it looks like a strip of light when it glows.
The earliest process is to weld the LED on the copper wire, and then cover the PVC pipe or use the equipment directly forming, there are two kinds of round and flat, its name according to the number of copper wire and the shape of the lamp belt to distinguish; Two lines are called the second line, the circle is in front of the circle plus the circle, that is, the circle second line; Flat in front of the flat word, that is, flat line.
Later developed into the use of flexible circuit board FPC to do the carrier, because its processing technology is more simple, quality is easier to control, longer life, color and brightness is higher and gradually replaced the earlier processing technology, gradually into the trend.
Conventional round two wire, round three wire, flat three wire, flat four lines, etc.
The colors are red, green, blue, yellow, white, colorful and so on.
Diameter: 10mm~16mm, it is widely used in building outline, bridge, guardrail, hotel, garden, ballroom, advertising decoration places, etc.
Two, the main characteristics and advantages of the lamp belt
1, soft, can curl like a wire.
2, can cut and extend.
3, the light source and circuit are completely covered in flexible plastic, insulation, waterproof performance is good, safe use.
4, strong weather resistance.
5, not easy to break, long service life.
6, easy to make graphics, text and other shapes; At present, it has been widely used in the decoration and lighting of buildings, Bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertising, signs, signs and so on.
Three, LED lamp belt life
Because LED is a constant current element, so different manufacturers of LED lights with constant current effect is not the same, of course, the life is therefore different. Of course, if the toughness of the copper wire or flexible circuit board of the lamp belt is not good, it will affect the life of the LED lamp belt.
Four, LED light belt in the maintenance of matters needing attention
1, anti-static: because LED is electrostatic sensitive element, if you do not do a good job of anti-static measures in the maintenance of LED light belt, it will burn out LED, resulting in waste. It is important to note that the soldering iron must be used with anti-static iron, and the maintenance personnel must also take anti-static measures (such as wearing electrostatic rings and anti-static gloves, etc.).
2. Continuous high temperature: LED and FPC, two important components of the LED lamp belt, are not sustainable high temperature resistant products. If the FPC in the continuous high temperature or is more than its withstand temperature, it will make the FPC covering film foam, directly resulting in the LED lamp scrap. At the same time, LED can not continue to withstand high temperature, in high temperature for a long time, its chip will be burned out by high temperature. Therefore, the soldering iron used in the maintenance of the LED lamp belt must be controlled by the temperature iron, the temperature is limited in a range, and it is forbidden to arbitrarily change and set. In addition, even so, it is also necessary to pay attention to the maintenance, the iron should not stay at the foot of the LED for more than 10 seconds, if more than this time, it is likely to burn out the LED chip.
3. Short circuit: many LED lights are bad because there is a short circuit at the foot. We must find out the real bad cause before maintenance. Otherwise, after hastily replacing the bad LED, it will continue to cause the chip of the LED to be broken down by the short circuit current when it is powered on again. Therefore, before replacing the new LED, we must first find out the real cause of the bad, the right medicine can get twice the result with half the effort.
