BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of decorating a pine decoration by an optical method, and more particularly to a method of decorating a pine decoration using an optical fiber.

2. Description of the Related Art Matsuzaka has been established in Japanese culture since ancient times as a decorative item used in the New Year, and has been used for many years. The most common type of pine decoration is the so-called Kadomatsu, which has a structure in which pine and bamboo are inserted into a pot-shaped container. In some cases, other trees, such as plums, may be added to the tree, or words celebrating the New Year, such as "Yukishin", may be used. A popular pine decoration alongside “Kadomatsu” is the so-called “Shimenawa”, which combines rope and pine. In addition, you can also see pine decorations on Gosho cars, fans, etc., which are used as New Year decorations.

[0002]

[Problems to be solved by the present invention] By the way, Matsudecoration is a traditional Japanese decoration, so the electric decoration method was not originally used. Therefore, they cannot be seen when the light is not illuminated, such as at night, so there was an aspect unsatisfactory for modern decoration. Therefore, in order to use it as a decoration even at night, it is necessary to illuminate it with some kind of light. However, it is cumbersome to prepare a separate light, so it is rarely used except in special cases. Therefore, when considering pine decorations as ornaments, the current situation is that the use environment is limited to bright places.

[0003] In the past, Christmas trees and the like were very simple compared to current ones. However, with the spread of electric decorations in the world, Christmas trees have gradually become more and more electric. Decoration has come to be given. In view of this, the current pine decorations are still very decorative in nature, and it is difficult to say that they meet the needs of today's lifestyles. . Furthermore, considering the environment of use such as housing conditions, it is desirable not only to have such a high degree of decorativeness but also not to require a very large space for use. In addition, it is desirable that the storage space does not require a large space. Considering ease of use, an energy-saving design that can be driven by batteries rather than relying on AC power is desirable for easy placement on a desk or the like. Accordingly, the problem to be solved by the present invention is to provide a pine decoration ornament that optically decorates a main part of a pine decoration such as a trunk or a branch and can easily obtain various products, large and small, at low cost.

The above objects of the present invention can be achieved by the following inventions.

(1) Each of the optical fibers extending from the converging portion of the optical fibers bundled below has a pine decoration composed of pine and bamboo applied at least along the trunk, branches and leaves of a pine, and a light source device below the pine decoration.

(4) The pine decoration according to any one of (1) to (3), wherein the light source has a spare light source. (5) The ornament according to any one of (1) to (4), wherein the light source is a light emitting diode.

[0005] The pine decoration according to the invention described in the above (1) is composed of pine and bamboo in which each optical fiber extending from the converging portion of the optical fibers bundled below is applied at least along the pine trunk, branches and leaves. What is claimed is: 1. A garland decoration comprising a pine decoration and a light source device disposed below the pine decoration, wherein the light source device is disposed such that a light source having a reflecting mirror is located below the optical fiber converging portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the specification of the present application, the scope of Kadomatsu means not only general Kadomatsu but also Kadomatsu with trees such as plums and celebrating the New Year, such as "Yukiharu". Including words, or "shimenawa" that combines rope and pine, and also includes New Year decorations such as Gosho cars and fans.

In the following, taking the case of using a kadomatsu as an example of a general pine decoration, its structure will be described in detail with reference to the drawings, together with the principle of the present invention and which part of the structure. State if the idea is implemented in minutes. In the present invention, an optical fiber 5 having a diameter of 0.4 to 0.5 mm is distributed to a main part constituting a pine decoration in a portion corresponding to a pot 2 of a kadomatsu 1. Preferably, the optical fiber has an outer diameter of 0.1 to 3 mm. At this time, the number of optical fibers varies depending on the main part, and is not particularly limited, but is 10 to 30,000, preferably 100 to 30,000, more preferably 100 to 20,000. The optical fiber is laid along the pine trunk 20 and the branches 21 from there, and the optical fiber is placed so that the tip of the optical fiber can be seen through the pine needles. At this time, it is preferable that a plurality of optical fibers be seen from the pine needles. Also, if the size of the kadomatsu is very large, it is convenient to divide the kadomatsu itself into several parts, which is convenient for storage etc. It is convenient to provide a joint part (not shown) for the optical fiber 5 so that it can be separated and connected at the divided part so that the connection part can be removed at the time of storage. .

In the present invention, the focusing unit 6 needs to receive the light from the light source 9 of the pot 2, so that the focusing unit 6 is close to, close to, or fitted to the top surface of the pot 2. Engaged. In order for light from the light source 9 to enter from the converging portion 6 of the optical fiber 5, at least the upper surface portion of the pot 2 where the converging portion 6 is disposed on the upper surface of the pot 2 is made of a transparent material. Preferably, it is formed of a transparent lid that covers the upper surface of the bowl 2. The bowl 2 is a lid having a height that covers components such as the light source 9, the rotating plate 7, and the motor 11 installed on the bottom plate 13, and the upper surface thereof is configured using a transparent lid. You may. As a material constituting the transparent portion, glass, an acrylic resin, or the like is preferable. When the pot 2 is used indoors, there is no particular need to consider waterproofing means. However, when the pot 2 is used outdoors, internal parts or devices such as the light source of the pot 2 are protected from water such as rain. Waterproofing measures should be taken to protect them. Further, the pot 2 needs to dissipate heat generated from components such as a light source housed inside, so that holes or slits penetrate the side walls and bottom, or a gap between the main body of the pot and the lid. It is advisable to take measures such as providing When a hole is provided in the side wall, the hole may be provided so as to penetrate the side wall at a right angle, or a hole inclined downward from the inside to the outside may be provided.

On the other hand, a light source in which a reflecting mirror 8 is adjusted so that light is incident on the converging portion 6 of the optical fiber 5 is installed in a portion corresponding to the bowl 2. At this time, a rotating plate 7 in which one or more types of light transmitting colors are disposed between the light source 9 and the converging portion 6 of the optical fiber 5. To arrange the colors, a method of fitting a colored acrylic plate or glass into an opaque disk such as a metal, or using the rotating plate itself by bonding several kinds of colored transparent materials, etc. Good. At this time, the rotating plate 7 should be installed with a sufficient space so as not to hinder the rotation of itself. The rotating plate 7 is connected to a motor 11 that rotates around the center of the rotating plate 7, and the rotating plate 7 rotates at a constant speed. When a plurality of colors are arranged on the rotating plate 7, the color of light incident on the converging portion 6 of the optical fiber 5 changes with rotation, and the color of light leaking from the tip of the optical fiber 5 can be changed with time.

Further, the positional relationship between the light source 9 and the converging portion 6 of the optical fiber 5 is as shown in FIG. 2, so that the light from the light source 9 is also incident on the lower end of the bamboo tube 3 of the kadomatsu 1. . If the bamboo tube 3 is a natural bamboo, remove the knots in advance or use an artificial bamboo tube 3 with no nodes so that light passes through the bamboo tube 3 and leaks from the tip of the bamboo tube 3. be able to. The artificial bamboo cylinder 3 may be made of transparent or non-transparent plastics. In the case of the transparent artificial bamboo cylinder 3, a coloring agent, for example, a green coloring agent is applied to the surface around the bamboo cylinder 3. Alternatively, the bamboo cylinder may be formed of transparent plastics mixed with a coloring agent. By doing so, the light source light is emitted from the upper part of the bamboo tube 3 and the light of the colorant leaks from the side surface of the bamboo tube 3, and the decorative effect can be improved.

When the lamp 91 is used as the light source 9, the lamp is used in a range of 0.1 w to 5 kW. However, since the lamp 91 has a life, there is a possibility that the ball may be broken when it is not expected. Matsushita 1 is originally “lucky”, so it is desirable that it can be quickly restored in the event of a broken ball. Therefore, as shown in FIG. 2, the spare lamp 10 of the light source 9 is arranged, and the lamp 91 can be replaced with one touch by sliding it. At this time, the reflecting mirror 8 of the light source 9 is provided with a hole 17 on the side surface thereof, and the lamp 91 or 10 is used with the hole 17 inserted therein. If only 91 can be replaced, the cost can be reduced.

In the above method, the lamp 91 is used as the light source 9, but the light emitting diode 16 can be used instead of the lamp 91 as shown in FIG. The three types of light emitting diodes, red light emitting diode 16a, yellow green light emitting diode 16b, and blue light emitting diode 16c, are combined as a set, and light emitted from these light emitting diodes 16a, 16b, 16c is directly transmitted from the focusing section 6 of the optical fiber 5. It is arranged so as to be incident on the optical fiber 5. Thus, unlike the case where the lamp 91 is used, it is not necessary to provide the rotating plate 7 between the light source 9 and the converging section 6 of the optical fiber 5. The light source using the light emitting diode includes a light emitting diode 16, an electric resistor (not shown), a controller 14, and a power supply 15, as shown in the circuit diagram of FIG. Here, the controller 14 is for changing the power supplied to the light emitting diode 16 with time, and in the case where the light emitting diodes of a plurality of colors are used as described above, the controller 14 changes the power to the focusing portion of the optical fiber with time. The color of the incident light can be changed.

Since the power consumption of a light emitting diode is usually about 5 to 30 mw per light emitting diode, there is a limit in increasing the brightness per light source as a light source. Therefore, it is necessary to increase the number of light emitting diodes in order to increase the brightness of the light emitting diodes. When the number of light emitting diodes is increased, the power consumption also increases. Therefore, the electric power may require 5 mW to 50 W, and sometimes several kW or more depending on the size of the pine decoration. According to the above configuration, the color of the light incident on the optical fiber can be changed without using the rotating plate and the motor for rotating the rotating plate, so that the space for installing the entire light source can be reduced. Further, since the light emitting diode has a very long life, there is no fear of breaking the ball, and there is no need to provide a spare light source as described above, so that the entire light source can be arranged in a narrower space. You. Further, the light emitting diode has extremely high luminous efficiency and can obtain strong light with a small amount of power, so that power consumption can be reduced and driving with a battery is facilitated. Therefore, when a light emitting diode is used as a light source, it is most suitable for producing a high-fashion, power-saving, small-sized kadomatsu that can be easily displayed on a desk.

[0017]

The present invention will be described below in more detail with reference to examples, but the present invention is not limited to these examples.

Embodiment 1 Here, a detailed description will be given of a kadomatsu in which light is emitted from the tip of bamboo using the same light source while decorating the kadomatsu with an optical fiber. As shown in FIG. 1, a focusing portion 6 of an optical fiber 5 is provided in a portion corresponding to the bowl 2 of the kadomatsu 1, and the optical fiber 5 is crawled along a trunk 20 and a branch 21 of the pine. Is set up so that it can be seen through the pine flock. At this time, as a material of the optical fiber 5, a plastic material is used in order to enhance safety, but a glass material can also be used, and the material is not particularly limited. About 10,000 optical fibers having a diameter of 0.5 mm were used as plastic optical fibers.

On the other hand, a lamp 91 or a lamp light source 9 adjusted by the reflecting mirror 8 so that light is incident on the converging portion 6 of the optical fiber 5 is installed directly below. It is necessary to select an appropriate output for the light source 9 depending on conditions such as the size of the kadomatsu 1 and the required brightness or thermal design. In this embodiment, the lamp light source 9 having an output of 30 W was used. Then, between the light source 9 and the converging portion 6 of the optical fiber 5, a rotating plate 7 on which a red, yellow, blue, and green heat-resistant plastic plate 12 that transmits light is interposed, so that the plastic is provided. The light passing through the plate 12 is colored. Of course, there is no need to use four types of colors, and a glass plate can be used instead of a heat-resistant plastic, and the material is not particularly limited. The rotating plate 7 is connected to a rotary driving machine composed of a motor and a gear through an axis provided at the center thereof perpendicular to the rotating surface so that the color of light incident on the optical fiber 5 changes with time. It is designed to rotate. The rotation speed can be arbitrarily selected depending on the gear ratio, but the rotation speed often used is usually about 3 to 60 rotations / minute.

In the present embodiment, furthermore, the light is leaked from the tip of the bamboo tube 3 of the kadomatsu 1. For this purpose, there is a method in which a light source different from the light source 9 is used immediately below the bamboo tube 3, but in this embodiment, the lamp light source 9 and the converging section 6 of the optical fiber 5 are used in order to use the light source 9 together. By arranging the lower end of the bamboo tube 3 and the rotating plate 7 as shown in FIG. 2, a part of the light from the light source passes through the plastic plate 12 provided on the rotating plate 7 and a part of the light comes from the bamboo tube. I tried to leak to 3 Further, a convex lens can be arranged on the path of the light source light entering the converging portion 6 of the rotating plate 7, and preferably, the colored transparent material 12 of the rotating plate 7 is fitted with a convex lens to improve the light intensity. It can also be done. Further, the surface of each convex lens can be colored in a desired color. In the bamboo tube 3, it is necessary that light incident from the end leaks out from the end. In the present embodiment, an artificial bamboo tube 3 having no nodes was used. However, when a real bamboo tube 3 was used, a node from which the nodes were removed in advance was used. The inner surface of the bamboo cylinder was painted silver to allow as much light as possible from the lower end to reach the tip.

In this embodiment, a spare lamp 10 light source is provided when the lamp 91 of the light source 9 is cut off. As shown in FIG. 3, the lamp used was a system in which the light reflecting mirror 8 of the lamp was fixed and only the inner lamp 9 was replaced, thereby reducing costs. For this purpose, as shown in FIG. 3, a hole 17 as shown in the figure was formed in the side surface of the reflecting mirror 8 so that the lamp could enter and exit therefrom. Also, the lamp can be slid with one touch so that the lamp can be replaced quickly. In this method, a long hole or a penetrating slit is provided in the bottom plate 18, and the bolt and the nut are fixed through the long hole or the penetrating slit, and when the position of the light source is to be moved, the bolt and the nut are loosened. Alternatively, the bottom plate 18 may be provided with an engagement groove, and the groove or the light source support may be slidably engaged with the groove, and the groove may be moved as a rail. The pot 2 used in the present invention is configured in consideration of heat dissipation from the light source during use and waterproofness. In this example, the pot 2 has such a small penetration that the rain does not enter the side wall of the pot. Many holes are provided.

Example 2 A kadomatsu was manufactured in the same manner as in Example 1 except that a light-emitting diode was used as the light source described in Example 1, and a small-sized (decorated indoor) miniature Kadomatsu was used as the kadomatsu. did. That is, here, a small-sized kadomatsu driven by the battery 15 using the light emitting diode 16 as a light source will be described in detail. In this example, a miniature kadomatsu having a height of about 200 mm was manufactured. The light source using the light emitting diode (LED) 16 is composed of three parts: an LED 16, a controller 14, and a power supply (battery) 15. As the LED light source, one light emitting diode 16 of each of three colors of red 16a, yellow green 16b, and blue 16c is used. The controller 14 is for changing the current flowing to the LED with time, and uses a module that can be easily programmed by a personal computer or the like. Nearly infinite combinations of colors are possible with the above three color combinations, and very complex color changes can be created. Dry batteries were used for the power supply. The power supply was designed to cover both the light emission of the LED and the drive of the controller, and a voltage of about 3 volts was required to drive the blue LED. Therefore, the power supply voltage was 4.5 volts. Power consumption is about 100 mW. If the size of the kadomatsu increases and the number of optical fibers increases, or if it is desired to increase the brightness of the light emitted from the end of the optical fiber, it is possible to respond by increasing the number of LEDs.
