Embodiment 1.
Hereinafter, Embodiment 1 of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the spiral tube jig 10 is attached to the straight tube type LED 20 at the time of use. One end of the LED 20 is the first LED end 21, and the other end is the second LED end 22. The spiral tube jig 10 is attached to the first LED end 21. The spiral tube jig 10 is made of resin. Further, the LED 20 constitutes an elongated member.

A spiral tube 30 is attached to the LED 20. The spiral tube 30 is a transparent spiral tube in which a transparent resin formed in an elongated and thin shape is spirally wound. The spiral tube 30 is inserted into an insertion hole 12 provided in the guide portion 11 of the spiral tube jig 10. Further, the spiral tube 30 contains a phosphorescent agent that absorbs and phosphorescents the light emitted by the LED 20. The spiral tube 30 shown in FIG. 1 is wound from the first LED end 21 to the second LED end 22 in the left-handed direction, but may be wound in the right-handed direction.

Since the spiral tube 30 containing the phosphorescent agent is attached to the LED 20, the spiral tube that phosphorescents the light of the LED 20 when the LED 20 is turned off due to a power failure or the like when the LED 20 is used as lighting. Thirty phosphorescent agents emit light to obtain a lighting effect. Further, the surface of the LED 20 can be protected by the spiral tube 30.

As shown in FIG. 2, the spiral tube jig 10 extends along the longitudinal direction of the LED 20 (see FIG. 1) and is connected to the semi-cylindrical fitting portion 13 that can be fitted to the LED 20 and the fitting portion 13. It has a guide portion 11 provided and an insertion hole 12 provided in the guide portion 11. Since the fitting portion 13 has a semi-cylindrical shape, two end portions 14 are formed in the circumferential direction. That is, the end portions 14 are separated from each other, and the fitting portion 13 is not formed. In the first embodiment, the diameter of the LED 20 is 32 mm, and the fitting portion 13 is formed in a shape and size that can be fitted to the LED having a diameter of 32 mm. Further, at the two end portions 14 of the fitting portion 13, protrusions 15 formed parallel to the extending direction of the fitting portion 13 are formed inward in the radial direction, respectively. The insertion hole 12 constitutes an insertion portion, and the fitting portion 13 constitutes a mounting portion. The diameter of the LED 20 may be any diameter other than 32 mm, and the fitting portion 13 may be formed in any shape and size that can be fitted to the LED 20 other than the diameter 32 mm.

FIG. 3 is a plan view of the spiral tube jig 10. The fitting portion 13 extends in the longitudinal direction A of the LED 20 (see FIG. 1). Further, the insertion hole 12 extends in the circumferential direction of the LED 20 and in the B direction having an angle difference θ with respect to the direction C perpendicular to the longitudinal direction A. That is, the guide portion 11 is not parallel to the longitudinal direction A, but is formed so as to have an angle difference corresponding to the angle difference θ in the direction B of the insertion hole 12. The direction B of the insertion hole 12 is formed so as to be in the same direction as the direction in which the spiral tube 30 (see FIG. 1) extends spirally with respect to the longitudinal direction A of the LED 20. Further, the insertion hole 12 is formed to be slightly wider than the width of the spiral tube 30.

Next, a method of attaching the spiral tube 30 to the LED 20 will be described using the spiral tube jig 10 of the first embodiment.
As shown in FIGS. 4 and 5, the operator inserts the LED 20 into the separation portion between the ends 14 of the fitting portion 13 of the spiral tube jig 10 with respect to the LED 20 installed on the ceiling or the like. Then, the spiral tube jig 10 is attached to the LED 20. As a result, the fitting portion 13 fits into the LED 20. At this time, a groove 23 is formed on the surface of the half-circumferential portion of the LED 20 in the circumferential direction. Therefore, the spiral tube jig 10 is attached to the LED 20 so that the protrusion 15 of the end portion 14 of the spiral tube jig 10 fits into the groove portion 23. As a result, the spiral tube jig 10 is fixed to the LED 20, and the spiral tube jig 10 is prevented from rotating in the circumferential direction.

Next, as shown in FIG. 6, the operator inserts the tip of the spiral tube 30 into the insertion hole 12 of the guide portion 11. Since the direction E extending spirally of the spiral tube 30 and the direction B of the insertion hole 12 are the same, the spiral tube 30 is inserted along the insertion hole 12. Next, as shown in FIG. 7, the operator rotates the spiral tube 30 in the direction D of the spiral in front of the insertion hole 12, so that the spiral tube 30 is further inserted into the insertion hole 12 and passes through the insertion hole 12. It is wound around the surface of the LED 20 while advancing in the direction E extending in a rear spiral shape. That is, the spiral tube 30 is wound around the surface of the LED 20 by the operator inserting the spiral tube 30 into the insertion hole 12 while rotating the spiral tube 30 in the spiral direction D on the spot.

Next, when the spiral tube 30 is continuously inserted along the insertion hole 12, the tip of the spiral tube 30 reaches the second LED end 22 as shown in FIG. As a result, the spiral tube 30 is held in a state of being spirally wound around the surface of the LED 20. In this state, the spiral tube 30 not wound around the LED 20 is cut at the position on the first LED end 21 side before being inserted into the insertion hole 12, and the spiral tube jig 10 is removed to the LED 20. The installation of the spiral tube 30 is completed.

When the spiral tube 30 is attached to the LED 20 by using the spiral tube jig 10 as described above, it is not necessary to rotate the spiral tube jig 10 with respect to the LED 20 due to the winding of the spiral tube 30. It is not necessary to orbit the spiral tube 30 around the LED 20. Therefore, when the space around the LED 20 is narrow and the space required for the rotation of the spiral tube jig 10 and the rotation of the spiral tube 30 cannot be secured, or the rotation of the spiral tube jig 10 and the rotation work of the spiral tube 30 Therefore, even if the space for inserting the operator's hand cannot be secured, the spiral tube 30 can be wound around the LED 20 simply by inserting the spiral tube 30 into the insertion hole 12 while rotating it in the direction D of the spiral. Can be done.

Further, in this case, it is not necessary to move the spiral tube jig 10 from the first LED end 21 during the work. Therefore, even in a place where the movement of the worker is restricted, the spiral tube 30 is simply inserted into the insertion hole 12 of the spiral tube jig 10 at hand without the worker moving. The spiral tube 30 can be wound over the entire length of the LED 20.

Further, since the direction E extending spirally of the spiral tube 30 and the direction B of the insertion hole 12 are the same, the spiral tube 30 is smoothly wound around the LED 20 along the insertion hole 12, and the spiral tube 30 is wound. Looseness is less likely to occur and winding workability is improved.

In this way, the spiral tube jig 10 for attaching or detaching the spiral tube 30 to the columnar LED 20 is connected to the fitting portion 13 that can be attached to the LED 20 and the fitting portion 13 to guide the spiral tube 30. The guide portion 11 and the insertion hole 12 provided in the guide portion 11 into which the spiral tube 30 can be inserted are provided. The direction B of the insertion hole 12 is the circumferential direction of the LED 20 and is perpendicular to the longitudinal direction A of the LED 20. Since the direction has an angle difference θ with respect to the direction C, the spiral tube can be attached to the elongated member without rotating the jig around the elongated member.

Further, it is a spiral tube mounting method in which a spiral tube is attached to a cylindrical elongated member, and is a fitting portion 13 that can be attached to the cylindrical LED 20 and a guide portion that is connected to the fitting portion 13 and guides the spiral tube 30. 11 and an insertion hole 12 provided in the guide portion 11 into which the spiral tube 30 can be inserted are provided, and the direction B of the insertion hole 12 is the circumferential direction of the LED 20 and the direction C perpendicular to the longitudinal direction A of the LED 20. On the other hand, since the spiral tube jig 10 having an angle difference is attached to the LED 20, the spiral tube 30 is inserted into the insertion hole 12 and attached to the LED 20, the jig is not rotated around the elongated member. The spiral tube can be attached to an elongated member.

In the first embodiment, as shown in FIG. 3, the direction B of the insertion hole 12 of the spiral tube jig 10 is a direction having a constant angle difference θ predetermined with respect to the longitudinal direction A of the LED 20. However, for example, the direction B of the insertion hole 12 can be adjusted with respect to the longitudinal direction A by configuring the guide portion 11 to be rotatable around the radial direction of the semi-cylindrical fitting portion 13. It may be configured.

Since the guide portion 11 is rotatably provided about the radial direction of the LED 20 in this way, the direction B of the insertion hole 12 can be adjusted with respect to the longitudinal direction A of the LED 20, and different spiral angles can be obtained. It can correspond to the attachment of the spiral tube 30 to have.

Further, since the fitting portion 13 has a protrusion 15 that can be fitted into the groove portion 23 formed on the surface of the LED 20, it is possible to prevent the spiral tube jig 10 from rotating in the circumferential direction of the LED 20.

Further, since the operator inserts the spiral tube 30 into the insertion hole 12 while rotating it in the spiral direction D of the spiral tube 30, the operator simply inserts the spiral tube 30 at hand without moving and spirals over the entire length of the LED 20. The tube 30 can be wound.

In the first embodiment, the direction B of the insertion hole 12 is the same as the direction E extending spirally of the spiral tube 30, but the insertion hole 12 can be inserted as long as it does not interfere with the insertion of the spiral tube 30. The direction B and the spirally extending direction of the spiral tube 30 may be different. Further, although the insertion hole 12 is formed to be slightly larger than the width of the spiral tube 30, the shape and size of the insertion hole 12 can be any shape and size as long as the insertion of the spiral tube 30 is not hindered. May be formed in. Furthermore, the insertion hole 12 was defined by the guide portion 11 and penetrated through the guide portion 11, but if there was no problem in guiding the spiral tube 30, for example, it was opened in the radial direction of the fitting portion 13. It may have any shape such as having a portion.

Further, in the first embodiment, a groove 23 is formed on the surface of the half circumference portion of the LED 20, and the protrusion 15 of the end portion 14 of the spiral tube jig 10 is fitted into the groove 23 with respect to the LED 20. By fixing the spiral tube jig 10 to the spiral tube jig 10, the spiral tube jig 10 is prevented from rotating in the circumferential direction, but the groove portion 23 may be formed on the entire circumference of the LED 20. Further, the spiral tube jig 10 is rotated in the circumferential direction by fixing the spiral tube jig 10 to the LED 20 by the force of the end portion 14 pressing the LED 20 without forming the groove 23 on the surface of the LED 20. You may prevent it from doing so.

Further, in the first embodiment, the spiral tube jig 10 is attached to the LED 20 by fitting the semi-cylindrical fitting portion 13 to the LED 20, but the spiral tube jig 10 is, for example, a clamp or the like. The spiral tube jig 10 may be attached to the LED 20 by holding the gripping member of the above in place of the fitting portion 13 and gripping the LED 20 by the gripping member.

Further, in the first embodiment, the spiral tube 30 containing the phosphorescent agent that absorbs and phosphorescents the light emitted by the LED 20 is used, but the spiral tube 30 in which the phosphorescent agent is coated on the surface instead of containing the phosphorescent agent is used. The same effect can be obtained by using 30. Further, although the spiral tube 30 is a spiral tube using a transparent resin, it may be a spiral tube using an opaque or translucent resin.
