1. A waterproof LED chain comprising:
- a plurality of link units;
a plurality of wire pairs connecting the link units in electrical series;
at least one wire pair connected to a link unit to form external power supply wires;
each link unit comprising at least;
a tray housing;
a PCB securely received in the housing;
a plurality of light emitting diode elements mounted on the PCB in electrical connection with the wire pairs at a wire pair connection point; and
cured waterproof resin inside the tray housing encasing the printed circuit board, the wire pair connection point to the PCB and a lower half of the light emitting diode elements;
wherein the cured waterproof resin inside the tray housing encasing the lower half of the light emitting diode elements forms a surface defining an outer cover sealing an opening of the tray housing to enclose the PCB, wherein the outer cover has a plurality of apertures corresponding to the number of said LED elements and the external power wires at a location where the LED elements and the external power wires protrude from the cured waterproof resin.

Abstract
A chain of LEDs is formed from link units connected by wire pairs in electrical circuit. At least one wire pair is connected to a link unit to form external power supply wires. Each link unit is made of a tray housing a PCB in the housing, and LEDs mounted on the PCB in electrical connection with the wire pairs. Cured waterproof resin inside the tray housing encases the printed circuit board, the wire pair connection point to the PCB and the lower half of the light emitting diode elements.
