Colorful flexible lamp strip with inverted structure

Abstract

The invention discloses a colorful flexible lamp strip with an inverted structure. A head is connected to a signal controller, the colorful flexible lamp strip comprises a plurality of flexible circuit board units and a plurality of LED light-emitting chips, the flexible circuit board units and the LED light-emitting chips extend in the length direction of the lamp strip, IC chips are arranged onthe flexible circuit board units, the IC chips are used for controlling the LED light-emitting chips to generate colorful light, the flexible circuit board unit comprises a circuit layer and a supporting layer, the LED light-emitting chip is covered with thixotropic silica gel, and the light-emitting angle of the LED light-emitting chip is changed by changing the colloid shape of the thixotropic silica gel, the supporting structure plays a role in supporting the flexible circuit board unit, so that the flexibility of the flexible circuit board unit is improved, and the bending angle of the flexible circuit board unit is controlled, and thus the LED light-emitting chip and the IC chip cannot fall off due to excessive bending of the flexible circuit board unit.

Description

technical field [0001] The invention relates to the technical field of light strips, in particular to a magic color flexible light strip with an inverted structure. Background technique [0002] In the existing illusion flexible light strips, LED light-emitting chips with built-in IC chips are generally used. Due to the complex internal structure of the LED light-emitting chips with built-in IC chips, multiple gold wires are required to be welded. Excessive bending can easily cause the gold wire to break or desolder. The patch-type LED lamp beads on the flexible light strip are welded on the long flexible circuit board, and then processed in different ways such as threading the sleeve and dripping glue. Glue and other series of processes, light strips also need to mount, wear sleeves and other processes, the production process is complicated and the cost is high; excessive bending or improper bending may cause the problem of lamp bead welding to break off and break the circ...

[0002] In the existing illusion flexible light strips, LED light-emitting chips with built-in IC chips are generally used. Due to the complex internal structure of the LED light-emitting chips with built-in IC chips, multiple gold wires are required to be welded. When excessively bent, it is easy to cause the gold wire to break or desolder

The patch-type LED lamp beads on the flexible light strip are welded on the long flexible circuit board, and then processed in different ways such as threading the sleeve and dripping glue. Glue and other series of processes, light strips also need to mount, wear sleeves and other processes, the production process is complicated and the cost is high; excessive bending or improper bending may cause the problem of lamp bead welding to break off and break the circuit, because the LED lamp bead It is a hard body, and the circuit board is a flexible body. The force point of the lamp bead is relatively large. Bending the circuit board many times may cause the lamp bead's soldering foot to break off the pad due to the large force.

Moreover, the luminous angle of the SMD LED lamp bead is small, usually only 120 degrees
