Problems solved by technology

This method realizes a simplified manufacturing process, and has a certain degree of bendability, but this kind of bending will make the stress of the metal wire larger and the deformation obvious, so that the welding point of the welding wire on the metal wire will not be correct. If it is firm, it will also cause the offset of the fixed position of the LED chip, which is not conducive to the reliability of the electrical connection and the stability of the LED fixation

Embodiment Construction

[0028] The LED light string structure of the present invention has the characteristics of flexibility and bendability. Its main body is plastic packaging material, and the interconnection structure is metal wire. The part can avoid the problem of weak soldering point and offset of fixed position of LED chip.

[0029] see Figure 1-3 , the LED light string of the present invention is a parallel packaging structure of a plurality of LED chips 60, which includes two metal wires 30 arranged in parallel, and the metal wires 30 should have a certain rigidity and be able to support the multiple LED chip 60 and make the LED chip 60 not be subjected to bending force. Preferably, the metal wire 30 is made of copper, which can be doped with various metals to form a copper alloy metal wire. In addition, the arrangement of the two metal wires 30 should match the spacing between the electrodes of the plurality of LED chips 60 .

[0030] The two metal wires 30 are bent to form a wave shap...

Abstract

The invention provides a manufacturing method of a flexible LED lamp string. The LED lamp string manufactured through the method has certain flexibility and can be bent. LED chips are connected in parallel by using a lead which is taken as a carrier, and the lead is arranged in a wave shape, and the wave-shaped lead is provided with a spread inclined section so that problems that welding points are not firm and fixing positions of the LED chips are deviated are solved. In a manufacturing process, only four dies need to be used, and the four dies are combined into three sets of dies so that packaging universality is realized, and cost can be saved.

Description

technical field [0001] The invention relates to the field of LED packaging, in particular to a method for manufacturing a flexible LED lamp string. Background technique [0002] The light string structure is widely used in the fields of outdoor lighting and decorative lighting because of its flexibility and flexibility. An existing light string method is to directly arrange LED chips on two linear metal wires, and then use welding wires to weld the LED chips to the metal wires. This method realizes a simplified manufacturing process, and has a certain degree of bendability, but this kind of bending will make the stress of the metal wire larger and the deformation obvious, so that the welding point of the welding wire on the metal wire will not be correct. If it is firm, it will also make the fixed position of the LED chip shift, which is not conducive to the reliability of the electrical connection and the stability of the LED fixation Contents of the invention [0003] ...
