AI Technical Summary
Technical Problem
When the existing FPC flexible circuit board is twisted, the LED chip is susceptible to large torque concentration, causing damage or desoldering, causing failure.
Method used
A reinforced flexible light strip was designed. By adding an auxiliary metal layer to the circuit board and optimizing the structure of the copper circuit layer, including the arrangement of main lines, branch lines, soldering pads and reinforcement disks, the strength of the circuit board was increased. and bending resistance, and improved protection of LED chips.
Benefits of technology
It improves the strength and bending and torsion resistance of the circuit board, protects the LED chip, and improves the uniformity of the light strip by changing the arrangement direction of the LED chip.

Abstract
The invention discloses a reinforced lamp strip which is characterized in that the reinforced lamp strip comprises a circuit board and LED chips welded on the circuit board, the LED chips are packaged through fluorescent glue, the circuit board comprises a top covering film or a top white oil layer, a copper circuit layer and a bottom covering film or a bottom white oil layer, the top covering film and the bottom covering film are both combined with the copper circuit layer through glue layers, and the top white oil layer and the bottom white oil layer are bonded together. An auxiliary metal layer is fixed on the outer surface of the bottom covering film or the bottom white oil layer, a reinforcing covering film or a reinforcing white oil layer covers the auxiliary metal layer, the reinforcing covering film is combined with the auxiliary metal layer through an adhesive layer, and the copper circuit layer comprises a first main circuit and a second main circuit. A plurality of branch lines are arranged between the main line I and the main line II, each branch line comprises an upper conducting bar and a lower conducting bar which are parallel to the main line I, the bottom end of each upper conducting bar is connected with the top end of the corresponding lower conducting bar through a transverse conducting bar, a bonding pad I is arranged on each upper conducting bar, a bonding pad II is arranged on each lower conducting bar, and a bonding pad II is arranged on each transverse conducting bar. The lower conducting bar of the previous branch circuit and the upper conducting bar of the adjacent next branch circuit are oppositely arranged, and the second bonding pad on the lower conducting bar and the first bonding pad on the upper conducting bar are arranged side by side up and down.
