In daily life, because the LED lamps have the advantages of rich colors, small volume, environmental protection, energy conservation, long service life and the like, the LED lamps become a common illumination mode at present, and along with the continuous deepening of LED application, LED manufacturers usually weld a plurality of LED light-emitting elements on a printed circuit board to form an LED lamp strip so as to improve the illumination brightness and the integration degree.

There are two main types of light bars in the prior art: flexible LED lamp strip and the hard lamp strip of LED. The flexible LED light bar is assembled by using an FPC (flexible printed circuit) as an assembly circuit board and using a paster, so that the thickness of the product is only the thickness of one coin without space; the common specification comprises 18 LEDs and 24 LEDs which are 30cm long, 15 LEDs, 24 LEDs, 30 LEDs and the like which are 50cm long, the Flexible Printed Circuit (FPC) can be cut off at will and can be extended at will without influencing light emission, and the FPC is soft, can be bent, folded and wound at will, and can move and stretch at will in a three-dimensional space without being broken. The LED hard lamp strip is suitable for being used in irregular places and places with narrow space, can be bent and wound at will, is suitable for being used in advertisement decoration, can be combined with various patterns at will, is assembled by using a PCB (printed circuit board) hard lamp strip and a surface mounted LED (light-emitting diode), is also assembled by using a direct-insert LED, and adopts different elements according to different requirements. The hard lamp strip has the advantages of being easy to fix and having the defects of being incapable of being bent randomly and not suitable for irregular places.

Because flexible LED lamp strip can be crooked and convolute, generally the priority in the hard lamp strip of LED in practical application, but because flexible LED lamp strip material is weak, when satisfying crooked and convolute in order to save area, can't add luminance or other light control inside the lamp strip, can't satisfy present day lighting needs.
