Technical area

The present invention relates to a fairy lights, and more particularly to an LED fairy lights having a series structure.

background

Due to manufacturing process limitations, the existing copper wire SMD LED string lights generally have a parallel structure, but rarely a row structure. At present, the row-pattern SMD LED string is usually formed by cutting the copper wire (enamel-insulated wire) to a length corresponding to the manufacturing requirements and then welding to the SMD LED. However, the enamel insulated wire is thinner for the copper wire SMD LED string, and the SMD LED for a pleasant appearance is usually very small, so that it is not easy to handle and difficulties for the automatic production occur.

Step 2: welding a positive electrode and a negative electrode of the SMD LED to two ends of the corresponding conductive platform in an extending direction of the conductive wire;

Step 3: then severing the conductive wire in the center of the back of the SMD LED; and

Step 4: Form a protective cover in a part of each SMD LED by dispensing and curing an adhesive.

Another production method for a row-structured LED light string comprising the following production steps:

Step 1: Prepare a long conductive wire with an insulating layer and press a crimp fold onto the conductive wire according to a predetermined distance and polish off conductive platforms to two ends of the crimp fold;

Step 2: welding a positive electrode and a negative electrode of the SMD LED to the conductive platforms at both ends of the squish in an extending direction of the conductive wire;

Step 3: then severing the crimp fold from the conductive wire; and

Step 4: Form a protective cover in a part of each SMD LED by dispensing and curing an adhesive.

As an improvement of the above two technical solutions, the conductive wire is hinged by a plurality of thin enamel-insulated wires or a plurality of thin enamel-insulated wires with at least one thin nylon thread.

As an improvement of the above two technical solutions, the method further comprises the following fifth manufacturing step: preparing a flexible, transparent and plastic inner protective tube, wherein the interior of the inner protective tube is hollow and the tube wall is internally provided with two mutually insulated power supply wires, which are arranged axially; Inserting the string of lights made in step 4 into the inner sleeve and electrically connecting the conductive wires to the two ends of the string of lights with the two leads and placing the at least one set of strings in the inner sleeve.

Furthermore, the method comprises the following sixth production step: wrapping the light chain produced in step 5 with an insulating sheath ( 6 ).

As an improvement of the above technical solution, the method further comprises the following sixth manufacturing step: wrapping the string of lights made in step 4 with an insulating sheath.

A row-structured LED string light comprises a conductive wire and SMD LEDs, characterized in that conductive platforms are evenly spaced on the conductive wire, a positive electrode and a negative electrode of each SMD LED at two ends of the respective conductive ones Platform in the direction of extension of the conductive wire are welded, a break in the middle of the conductive platform is formed to separate the two ends of the conductive platform; and a protective sheath formed by dispensing and curing an adhesive outside the SMD LED envelops the same.

As an improvement of the above technical solution, the fairy lights further include that the interior of the inner protective tube is hollow and the tube wall is provided internally with two mutually insulated power supply wires, which are arranged axially; in that the fairy light chain produced in step 4 is arranged in the inner protective tube and that the conductive wires at the two ends of the fairy lights are connected to the two current supply wires and that the at least one group of fairy lights is placed in the inner protective tube.

Furthermore, the inner tube is made of flexible and translucent plastic.

Next, the lights are outside surrounded by an insulating sheath.

The invention has the advantageous effects that the SMD LEDs are first welded to the long conductive wire, then the conductive wire is severed to form the series structure, and then the LED string is relatively comfortable with an automatic Process can be produced; In addition, the production efficiency and structural stability in the manufacturing process are superior to those in the existing manufacturing process in which the wires are first severed and then the welding is performed. Moreover, by means of the protective cover formed by dispensing an adhesive and curing in the fourth step, the SMD LEDs can be efficiently protected against breakage by the conductive wire.
