Abstract

A method of making a string light is disclosed. The method includes providing a flat cable comprising at least 4 wires; soldering one or more light chips to at least 2 of the 4 wires of the flat cable; cutting the at least 2 of the 4 wires at a plurality of locations; and connecting a voltage reducing box to the wires.

Claims (35)

1. A method of making a string light comprising:

providing a flat cable comprising at least 4 wires;

soldering one or more light chips to at least 2 of the at least 4 wires of the flat cable;

cutting the at least 2 of the at least 4 wires at a plurality of locations; and

connecting a voltage reducing box to the wires.

2. The method of claim 1 , wherein the voltage reducing box comprises a resistor.

3. The method of claim 1 , wherein the voltage reducing box comprises a combination of at least one resistor and at least one capacitor.

4. The method of claim 1 ,

wherein the at least 4 wires comprise 2 outer wires and 2 inner wires, the 2 outer wires thicker than the 2 inner wires;

wherein each of the one or more light chips comprises 2 poles; and

wherein soldering the one or more light chips to at least 2 of the at least 4 wires of the flat cable comprises soldering one of the poles to one of the inner wires and the other pole to the other inner wire of the flat cable.

5. The method of claim 1 ,

wherein the at least 4 wires comprise 2 wires on a first side of the flat cable and 2 wires on a second side of the flat cable, the 2 wires on the first side thicker than the 2 wires on the second side;

wherein each of the one or more light chips comprises 2 poles; and

wherein soldering the one or more light chips to at least 2 of the at least 4 wires of the flat cable comprises soldering one of the poles to one of the 2 wires on the second side and the other pole to the other wire on the second side of the flat cable.

6. The method of claim 5 , wherein each of the one or more light chips comprises a two-pole LED chip.

7. The method of claim 1 ,

wherein the at least 4 wires comprise 2 outer wires and 3 inner wires, the 2 outer wires thicker than the 3 inner wires;

wherein each of the one or more light chips comprises a ground, a 5 volt power, and a data input; and

wherein soldering the one or more light chips to at least 2 of the 4 wires of the flat cable comprises soldering the ground, the 5 volt power, and the data input of each of the light chips on a respective inner wire of the flat cable.

8. The method of claim 1 ,

wherein the at least 4 wires comprise 2 wires on a first side of the flat cable and 3 wires on a second side of the flat cable, the 2 wires on the first side thicker than the 3 wires on the second side;

wherein each of the one or more light chips comprises a ground, a 5 volt power, and a data input; and

wherein soldering the one or more light chips to at least 2 of the at least 4 wires of the flat cable comprises soldering the ground, the 5 volt power, and the data input of each of the one or more light chips on a respective wire on the second side of the flat cable.

9. The method of claim 1 , further comprising connecting a function controller to the flat cable, the function controller configured to control an operation of the string light.

10. The method of claim 1 , further comprising connecting a dual color function controller to the flat cable, the dual color function controller configured to control dual color polarless LEDs for multifunctional use.

11. The method of claim 1 , further comprising connecting an RGB function controller to the flat cable, the RGB function controller configured to control RGB sync flash LEDs for multifunctional use.

12. The method of claim 1 , wherein the voltage reducing box reduces the voltage of the string light to between 100V and 230V.

13. The method of claim 1 , wherein the one or more light chips comprise at least 2 light chips; and wherein at least 2 of the at least 2 light chips are connected in parallel.

14. The method of claim 13 , wherein flat cable comprises at least 5 wires; and wherein the voltage reducing box comprises a reduce voltage and Code 0 RGB LED function control box.

15. The method of claim 1 , further comprising encapsulating each of the one or more light chips with a light head.

16. The method of claim 1 , wherein the one or more light chips comprise at least 2 light chips; and the method further comprises grouping the at least 2 light chips into at least one light source.

17. The method of claim 16 , wherein each of the plurality of light sources comprises a same number of light chips.

18. The method of claim 16 , wherein at least two of the plurality of light sources comprise a different number of light chips.

19. The method of claim 1 , further comprising clamping the at least 4 wires with fasteners to form light sources.
