The earliest process is to weld the LED on the copper wire, and then put on the PVC pipe or the use of equipment directly molded, there are two types of round and flat, its title according to the number of copper wire and the shape of the lamp belt to distinguish, two lines called the second line, the circle in front of the round, that is, round second line;

Later developed into the use of flexible circuit boards, that is, FPC to do the carrier, because of its easier processing technology, easier quality control, longer life, higher color and brightness, and gradually replaced the earlier processing technology, a gradual trend. Because the lamp belt above is generally welded led, so there are many called LED light belt, but because the noun is too long and simplified into a lamp belt.
