Description

  The present invention relates to a rope light body of a rope light as a decoration light used for decoration on a store decoration, a Christmas tree, and the like, and a manufacturing method thereof.

There is a decoration light called a rope light among the decoration lights that can be displayed in stores and Christmas trees.
As shown in FIG. 6, the rope light main body 1 constituting this rope light is configured such that the miniature light bulb 4 is spaced from the hollow portion 3 of the long transparent tube 2 formed of a synthetic resin material such as vinyl chloride. A large number of them are arranged continuously, and the lead wire 5 connected to the miniature light bulb 4 is embedded in the back side 2A of the tube 2.
By the way, since the rope light is mainly used for decoration, the long rope light main body 1 is often used by being bent into a desired motif for convenience of decoration.
However, since the tube 2 is formed of a synthetic resin material even if the rope light body 1 is bent into a desired motif shape, the bent motif shape cannot be maintained by itself.
Therefore, as shown in FIG. 7, for example, when the rope light body 1 is to be bent into a star shape, a star-shaped frame 6 is prepared separately, and the rope light body 1 is attached to the frame 6. The rope light body 1 is bent along the outer peripheral surface 6A into a star shape, and the rope light body 1 is connected to the frame 6 with a thin string 7 or the like so that the rope light body 1 maintains the star shape.
For this reason, when it is desired to make the rope light main body 1 into a desired shape, it is necessary to prepare a frame 6 having that shape separately, and the rope light main body 1 is arranged along the frame 6 to provide the rope light main body. Since it is necessary to connect 1 and the frame 6 with the string 7 etc., the decoration work of the rope light main body 1 becomes complicated.
In addition, when the rope light main body 1 is decorated using the frame 6, the frame 6 is also visible, so that the appearance quality is deteriorated such as poor appearance.
Furthermore, the conventional rope light main body 1 has a problem that it is weak against an external force that is pulled or twisted from the structure.
Therefore, when the rope light body 1 is bent into a certain shape by inserting a flexible plastic core (wire, etc.) into the hollow portion 3 of the tube 2 of the rope light body 1, the rope light body 1 is bent. It is possible to maintain the shape of the rope light body 1 and increase the strength of the rope light body 1, but a plurality of miniature light bulbs 4 are disposed in the hollow portion 3 of the conventional rope light body 1 at intervals. Therefore, it is difficult to insert the plastic core material.
Furthermore, when the hollow portion 3 is made large in diameter so that a plastic core material can be inserted, the rope light main body 1 also becomes large in diameter, which deteriorates the appearance and decreases the decorative value.

  The present invention has been made in view of the above facts, and can maintain the state when the rope light body is bent and can improve the strength of the rope light body, and further the appearance quality of the rope light body does not deteriorate. And a manufacturing method thereof.

The invention according to claim 1 is a tube comprising an inner tube formed of a synthetic resin material and having an inner tube formed of a synthetic resin material, and an outer tube formed of the synthetic resin material. A hollow portion formed in the tube along the longitudinal direction of the tube, a lead wire embedded in the outer tube on the back side of the tube along the longitudinal direction of the tube, and a longitudinal portion of the tube in the hollow portion. An LED light arranged continuously with a gap along the direction and connected to the lead wire, and the hollow portion between the LED light and the back side of the tube in the longitudinal direction of the tube And a plastic core material inserted along.
According to a second aspect of the present invention, there are provided a plurality of LED lights continuously arranged at intervals, a plastic core material arranged along the LED lights arranged continuously, and the LED light and the plastic core material. Is inserted into the cylindrical inner tube and a lead wire is disposed outside the inner tube, and the LED light and the lead wire are connected through a connection through hole formed in the inner tube, and this state The LED light, the plastic core material, the inner tube, and the lead wire are inserted into a tubular tube-forming mold, and the heated synthetic resin material is injected between the inner tube and the tube-forming mold. The rope light main body is manufactured by forming the outer tube integrally with the outer side of the inner tube to form the tube.
The invention of claim 3 is characterized in that the LED light is a chip-type LED light.

The rope light main body of the present invention has an excellent effect that the bent shape can be maintained even when the rope light main body is bent and the strength of the rope light main body can be improved.
In addition, the rope light main body of the present invention has the appearance quality of the rope light main body because the light of the LED light is not obstructed by the plastic core material when the rope light main body is turned on, or the plastic core material does not appear in the shadow. It has the outstanding effect that the fall of can be prevented.
The method for manufacturing a rope light body of the present invention has an excellent effect that the rope light body can be manufactured.
