Abstract

A method of producing a light-emitting-diode (LED) rope light includes the steps of preparing a plurality of light seats defining a recess therein and a plurality of metal wires having two conductive plates connected to two ends thereof; positioning two conductive plates from two different metal wires in each light seat; forming the light seats into light-emitting diodes; serially connecting the light seats to provide an LED light string; positioning the LED light string into a hollow power cord holder with two electrodes of the LED light string connected to two power cords embedded in the power cord holder; and quickly enclosing said power cord holder with a transparent outer tube by way of injection molding to form an LED rope light.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a method of quickly producing a light-emitting-diode (LED) rope light, and more particularly to a method of producing an LED rope light at largely reduced manufacturing cost and shortened time. BACKGROUND OF THE INVENTION

[0002] A conventional rope light includes a plurality of bulbs as its light sources. These bulbs are serially connected to one another to form one or two bulb strings, which are then set in a long core tube. The core tube is cut at an outer surface to provide a longitudinal opening, via which the bulb string or strings are positioned into the core tube. Two power cords having different polarities are embedded in two opposite sides of a wall of the core tube. The two embedded power cords are cut at staggered positions to expose bare wires, to which lead wires of the first and the last bulb in the bulb strings are separately electrically connected to emit light. The core tube with bulbs is then drawn into...
