Talking about LED light strip
First, what is the LED light strip?
The lamp strip refers to the LED lamp is soldered on the copper wire or the strip flexible circuit board by a special processing technology, and then connected to the power source for illumination, and is named after a light band when it emits light. The earliest process is to solder the LED on the copper wire, and then put it on the PVC pipe or directly form it by using equipment. There are two kinds of round and flat. The title is distinguished by the number of copper wires and the shape of the lamp strip. It is called the second line, and the circle is added with a circle in front, that is, a circle of two lines; the flat shape is preceded by a flat word, that is, a flat two line. Later, it developed into a flexible circuit board or FPC as a carrier. Because of its simpler processing technology, easier control of quality, longer life, higher color and brightness, it gradually replaced the earlier processing technology and gradually became a trend.
Conventional round two lines, round three lines, flat three lines, flat four lines, etc.; colors are red, green, blue, yellow, white, colorful and so on. Diameter: 10mm---16mm is widely used in building contours, bridges, guardrails, hotels, forest gardens, dance halls, and advertising decoration.
Second, the main features and advantages of the light belt?
1, soft, can curl like a wire.
2, able to cut and extend.
3. The bulb and circuit are completely covered in flexible plastic, which has good insulation and waterproof performance and is safe to use.
4. Strong weather resistance.
5, not easy to break, long service life.
6, easy to produce graphics, text and other shapes; has been widely used in buildings, bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertising, signs, signs, etc. illumination.
Third, how long is the life of the LED light strip?
Since the LED is a constant current component, the LED lamps produced by different manufacturers have different constant current effects, and the life expectancy is different. Of course, if the copper wire of the lamp strip or the flexible circuit board has poor toughness, it will affect the life of the LED strip.
Fourth, what are the precautions for LED lamp belts during maintenance?
1. Anti-static: Because LED is a static-sensitive component, if you do not take anti-static measures when repairing LED strips, it will burn out the LED and cause waste. It should be noted here that the soldering iron must use an anti-static soldering iron, and maintenance personnel must also take anti-static measures (such as wearing static rings and anti-static gloves).
2, continuous high temperature: LED light strip two important components of LED and FPC, are products that can not continue to withstand high temperatures. If the FPC continues to heat up or exceeds its temperature, it will cause the FPC's cover film to foam, which will directly cause the LED lamp to be scrapped. At the same time, the LED can not continue to withstand high temperatures, and the chip will be burned at a high temperature for a long time under high temperature. Therefore, the soldering iron used in the maintenance of the LED strip must use a temperature-controlled soldering iron to limit the temperature to a range, and it is forbidden to change and set it. In addition, even if this is the case, it should be noted that the soldering iron should not stay in the LED pin for more than 10 seconds during maintenance. If this time is exceeded, the LED chip is likely to burn out.
3, short circuit: Many LED lights are bad because there is a short circuit at the foot, you must find out the real bad cause before maintenance. Otherwise, after rushing to replace the defective LED, the chip of the LED will continue to be broken by the short-circuit current when the power is turned on again. Therefore, before replacing a new LED, we must first find out the real cause of the problem, and the right medicine can do more with less.
