There are 60cm, 80cm and so on, different users have different specifications. And can be arbitrarily cut off the light can not affect any extension. The FPC flexible material can be bent, folded,LED sign, winding,display boards, three-dimensional space can be moved around and stretch without breaking. Irregular areas for small places and space, but also because any bending and winding can be suitable for any combination of advertising in a variety of decorative motifs.
, LED light bar is made with the PCB board assembly circuit board hardware, LED useful for the assembly of SMD LED, LED-line is also useful for assembly, depending on the different needs of different components. Light bar has the advantage of easier fixation,LED open sign, processing and installation are relatively easy; disadvantage is not free to bend, not suitable for irregularities. SMD LED light bar have used 18 LED, 24 颗 LED, 30 颗 LED, 36 颗 LED, 40 颗 LED such a good variety of specifications; with line LED's are 18, 24, 36, 48 different specifications, there is also a positive side, the side known as the Great Wall Light shining.
LED lights with the production because the threshold into the low, so many people who launched this project. But those who have experience or a way to identify, regular producers and the production of LED lights with LED lights with cottage version (ie within the rental depends on the products produced by manual operation) is a glance from the appearance out. Mainly in the following areas: 1, see spot. LED lamp with a regular manufacturer of LED lights with the production of SMT chip technology is used.
with solder paste and reflow process production. Therefore, LED lights to bring the volume of solder joints with smooth and not many joints cylindrical arc from the FPC pad at the extension to the LED electrodes. The LED lights with cottage version of the volume of solder joints is uneven,vinyl banner, mostly a dot wrap welding foot, while there will be varying degrees of tin tip appeared, which is a typical phenomenon of manual welding.
