LED flexible circuit board

Abstract

The invention discloses an LED flexible circuit board, which comprises a metal foil layer and a covering layer. The covering layer is provided with a window for welding an LED element, the metal foil layer forms an LED circuit, and a positive electrode pin and a negative electrode pin of the LED circuit extend out of the end part of the metal foil layer. Through the above scheme, as the positive electrode pins and the negative electrode pins extend out of the end parts of the LED flexible circuit boards, when the LED flexible circuit boards are used for assembling the flexible LED lamp strip, the positive electrode pins and the negative electrode pins can be respectively fixed on the corresponding wires of the wire array through the connecting conductors, and two adjacent LED flexible circuit boards can also be connected through the connecting conductors. The LED flexible circuit board is simple in structure, electric connection of the LED flexible circuit board, the connecting conductor and the wire array in the flexible LED lamp strip can be achieved without welding, the situation that the LED flexible circuit board is prone to being affected by high temperature and damaged due to the fact that high-temperature operation is needed in the welding process is avoided, the connecting mode is simple and convenient, and the production efficiency of assembling the flexible LED lamp strip can be improved.
