What is the material of LED lamp belt?
The basic concept of LED: LED (Light, Emitting, Diode), LED is a solid state semiconductor device, which can directly convert electricity into light. The heart of LED is a semiconductor wafer with one end attached to the LED lamp strain on one bracket, one end with the negative electrode, and the other end connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a "P-N" junction". When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence.
LED lamp belt refers to the LED assembly in FPC band (FPC) or PCB hard, because of the shape of the product as a band name. Because of long service life (normal life expectancy of 8~10 hours), green and gradually emerging in all kinds of decoration industry. The light belt is the abbreviation of the LED light belt. Most people are not accustomed to the noun when they say it is too long, so the LED in front is omitted. It is called the light belt directly. In this way, the band with the name also includes a lot of big, second line, big three lines, round, second line and so on, the direct use of wire to connect LED, instead of FPC or PCB old band, of course, also includes flexible light band and hard light belt.
Sort:LED lights are divided into two types of flexible LED lamp band and LED hard light strip, but they also contain the old band with wire connecting LED, such as flat three wire, flat four wire band and so on.Difference：1, flexible LED light strip is done using FPC assembly line board, with patch LED assembly, the thickness of only one coin thickness, Mitutoyo LED lamp with space; general specifications 30cm 18 LED, 24 LED and 15 LED 50cm long, 24 LED, 30 a LED. There are 60cm, 80cm and so on, different users have different specifications. The utility model can be cut at will, and can be extended at any time, and the luminous effect is not affected. The FPC material is flexible and can be bent, folded and wound freely. It can be moved and stretched freely in three-dimensional space without breaking. The utility model is suitable for irregular places and space narrow places, and can also be arbitrarily bent and winding, and is suitable for arbitrarily combining various patterns in advertisement decoration.2, LED light bar is PCB hard to do assembly circuit board, LED SMD LED assembly useful, but also useful in line LED assembly, as required by different components and different. The advantage of hard light bar is easier to fix, and the processing and installation are more convenient. The disadvantage is that it can not bend freely and is not suitable for irregular place. Light bar with patch LED with 18 LED, 24 LED, 30 LED, 36 LED, 40 LED and so on many kinds of specifications; used in line LED 18 star, 24 star, 36 star, 48 stars of different specifications, also have a positive side, and side light called the Great Wall lights.
