High-voltage LED string light and method of manufacturing thereof
A light assembly of a string light is disclosed. The light assembly includes a first wire and a second wire, each of the first wire and the second wire comprising an end exposing copper strands; a first light-emitting diode (LED) chip soldered to the exposed copper strands of the first wire and the second wire; a colloid encapsulating the first LED chip soldered to the first wire and the second wire; a light head securing the colloid and a part of the first wire and the second wire; and a decorative shell secured onto the light head and enclosing the colloid encapsulating the first LED chip.
1. A method of making a light assembly of a string light, the method comprising:
providing a first wire and a second wire;
stripping an end of each of the first wire and the second wire of insulation to expose a portion of copper strands of each of the first wire and the second wire;
encapsulating the first LED chip with a colloid;
attaching a light head to the first wire and the second wire after the first LED chip is encapsulated with the colloid; and
securing a decorative shell on the light head after the light head is attached to the first wire and second wire,
wherein the decorative shell and the light head enclose the colloid encapsulating the first LED chip.
2. The method of claim 1 , further comprises placing a rear plug in a space between the first wire and the second wire where the first wire and the second wire diverge.
3. The method of claim 1 , wherein soldering the first LED chip to the first wire and the second wire comprises soldering an anode of the first LED chip to the exposed copper strands of the first wire and soldering a cathode of the first LED chip to the exposed copper strands of the second wire.
4. The method of claim 1 , wherein the light head is assembled or made by foam injection.
5. The method of claim 1 , wherein the colloid is formed over the first LED chip using injection molding, casting, or foam injection.
6. The method of claim 1 , further comprises soldering a second LED chip to the exposed copper strands of the first wire and the second wire.
