Hereinafter, some embodiments according to the present invention will be described with reference to the accompanying drawings.
[First Embodiment]
As shown in FIG. 1, the linear illuminant 100 according to the first embodiment includes a linear light source 10A, a coating layer 20 that covers the periphery of the light source 10A, and a holder that is attached to both ends of the coating layer 20. 30 is provided as a component. The linear illuminant 100 includes a curl portion 3 in which a predetermined range of the light source 10A and the coating layer 20 is spirally wound, and straight portions 5 following both ends of the curl portion 3. The holder 30 is attached to each straight portion 5.

As shown in FIGS. 2A and 2B, the curl portion 3 of the linear illuminant 100 extends linearly when an external force, for example, a tensile external force T1 is applied to the axis C1 of the curl portion 3, and the external force T1 If you release, it will return to its original spiral shape. That is, the curl portion 3 represents a form in which no external force is applied to the linear light emitting body 100. The same applies to the straight portion 5. For example, when an external force T2 is applied to the axis C2, the straight portion 5 is bent, but the straight portion 5 is linear unless an external force is applied.

[Light source 10A]
The light source 10A according to the present embodiment is composed of a linear inorganic EL (Inorganic ELectro-Luminescence: IEL) light source as an example. Inorganic EL is true electroluminescence that occurs when a voltage is applied to a phosphor of an inorganic compound.
Although not shown, the light source 10A includes, as an example, a cylindrical core electrode, a reflective layer laminated on the outer peripheral surface of the core electrode, a light emitting layer laminated on the outer peripheral surface of the reflective layer, and a light emitting layer. A transparent electrode laminated on the outer peripheral surface is provided. When electric power is supplied from the AC power source between the core electrode and the transparent electrode, light is emitted from the entire length and the entire circumference of the transparent electrode, which is the outermost layer of the light source 10A. This power is supplied via an inverter.

The light source 10A described here shows an example composed of an inorganic EL having a linear shape by itself, but the present invention is not limited to this form. For example, as the light source 10A, a linear organic EL, a linear LED (light emitting diode), or the like can be used. Further, the light source 10A can also be configured by wrapping a band-shaped light emitter, for example, an inorganic EL, around a linear member that does not emit light by itself. This form will be described later.

Further, the light source 10A belongs to the curl portion 3 which is expanded and contracted and the straight portion 5 which is bent. Therefore, the light source 10A is required to have at least flexibility to withstand deformation such as bending and twisting. Some linear inorganic ELs, organic ELs and LEDs on the market meet this requirement.
The cross-sectional shape of the light source 10A is not limited, and an ellipse including a perfect circle, a polygon, or the like is arbitrary. However, assuming that the curl portion 3 and the straight portion 5 are bent, the cross section of the light source 10A is most preferably a perfect circle having no directionality.
The diameter of the light source 10A is arbitrary, and may be selected according to the application of the linear light emitter 100. As an example, the diameter of the light source 10A is selected from the range of 1 to 10 mm so that deformation such as bending and twisting occurs reasonably.
The emission color of the light source 10A is also arbitrary, and emission colors such as blue, yellow, green, and red are widely adopted.
Further, the light source 10A can adopt a form in which light is constantly emitted and a form in which light is blinking. The inorganic EL emits light by receiving power supplied from the inverter, but the inverter may have a function of selecting constant light emission or blinking light emission.

[Coating layer 20]
Next, the coating layer 20 will be described.
The coating layer 20 covers the light source 10A from the surroundings and holds the light source 10A.
The coating layer 20 causes the linear illuminant 100 to exhibit elasticity and springiness. This is called the first requirement of the coating layer 20. Further, the coating layer 20 has the transparency necessary for transmitting the light emitted from the light source 10A and visually recognizing it from the outside. This is called the second requirement of the coating layer 20. This second requirement is a requirement that is not required for a so-called curl cord that functions as an electric wire.

In order to satisfy the first requirement, the coating layer 20 is made of a resin material. The resin material is selected from a thermoplastic resin and a thermosetting resin according to the intended use.

Examples of thermoplastic resins include vinyl chloride-based and polyester-based resins. All of these resins have electrical insulation and transparency. Here, the term "transparent" refers to the property of transmitting light, and can be classified into colorless transparent having no color and colored transparent having a color. These resins can also be made colored and transparent by containing a colorant.
To give an example of a thermosetting resin, there are urethane-based resins and synthetic rubber-based resins other than urethane-based resins. These resins can also have electrical insulation and transparency. These resins can also be made colorless and transparent, or can be made colored and transparent by containing a colorant.
Thermoplastic resins and thermosetting resins lose their transparency depending on the content of the colorant.

A transparent resin is used to satisfy the second requirement. Therefore, among the above-mentioned thermoplastic resins and thermosetting resins, colorless transparent and colored transparent materials are selected.

The coating layer 20 covers the light source 10A from the surroundings and holds the light source 10A, but it is desired to have a wall thickness corresponding to this function. This wall thickness is typically in the range of 1.0 to 3.0 mm. Depending on the application and the like, it is possible to have a wall thickness outside this range.

[Manufacturing method of linear illuminant 100]
The linear illuminant 100 can be manufactured by the same manufacturing method as the so-called curl cord. An example of the schematic process is as follows.
First, a softened resin material is supplied around the continuously traveling light source 10A to form a coating layer 20 to obtain a precursor of the linear illuminant 100. This precursor has a spiral curl. For curl, the precursor is wrapped around a straight bar and treated according to the resin material. For example, if the coating layer 20 is a thermoplastic resin, the precursor wound around the bar is heated to a predetermined temperature at which a plastic state can be obtained and then cooled. This gives the linear illuminant 100 spirally wound, but by reversing the winding direction after cooling, the linear illuminant 100 can be imparted with springiness.
The winding range is determined according to the application and the specification state. The linear illuminant 100 shown in FIG. 1 is wound except for both ends, but one of the straight portions may be cut off and used, or the straight portions at both ends may be cut off and used. can.

[Expansion and contraction of the linear illuminant 100]
As shown in FIGS. 2A and 2B, the linear illuminant 100 provided with the curl portion 3 is brought into a state of being extended from a state of being contracted in the direction of the axis C1 and returned from a state of being expanded to a state of being contracted. Can be done. Typically, the unused linear illuminant 100 is in a contracted state and the used linear illuminant 100 is in an elongated state. Here, when used, electric power is supplied to the light source 10A, and the light source 10A emits light. However, depending on the application and the state of use, it is possible to supply electric power to the linear light emitter 100 in both the contracted state and the stretched state to cause the light source 10A to emit light.

[effect]
Next, according to the linear light emitting body 100, where the following effects are exhibited, the utility value of the linear body having a decorative effect can be enhanced.
As described above, the linear illuminant 100 can easily obtain a contracted state (FIG. 2A) and an extended state. Therefore, since the linear illuminant 100 stored in a shrunk and compact state can be stretched at the time of use, it is easy to handle the shrunk unused state and the stretched used state alternately. .. On the other hand, in a straight linear illuminant, it is necessary to wind it around a reel or bundle it in some way when not in use, and it is necessary to untie it to make it in an extended state, so it has not shrunk. Alternating handling between the state of use and the state of extended use is complicated.

Next, the linear illuminant 100 can select the length in the direction of the extended axis C1 from the range of, for example, 3 to 5 times the length in the original contracted state. Moreover, since the curl portion 3 has a spring property, if both ends are properly supported, the curl portion 3 does not need to be provided with a special support means in the range of the original length to 5 times the original length. 3 can prevent it from hanging down. Therefore, according to the linear light emitting body 100, the light emitting region can be maintained at substantially the same height from the ground in both the contracted state and the stretched state.

Next, in the linear illuminant 100, the distance between the linear illuminants 100 spirally wound is different between the contracted state and the expanded state. That is, if the light source 10A is made to emit light in both the contracted state and the extended state, the one that visually recognizes the light emission is expanded to the contracted state by recognizing the distance between the wound linear light emitters 100. The states can be distinguished. Therefore, this difference in light emission interval can be used as some means of information transmission.

Further, the linear illuminant 100 is provided with holders 30 and 30 at the straight portions 5 at both ends, respectively. Since the holders 30 and 30 have higher strength than the coating layer 20, if the portions of the holders 30 and 30 are supported by a separately provided support, it is possible to avoid applying an excessive load to the straight portion 5. Can be done. As a result, the life of the linear light emitter 100 can be extended.

The strength of the spring can be changed depending on the coating material used, the thickness of the coating material, and the winding diameter.
The strength of the spring force differs depending on the intended use, but the product can be processed accordingly.

[Second embodiment: light reflector 25 on the coating layer 20]
Next, the linear illuminant 200 according to the second embodiment of the present invention will be described with reference to FIG. In the following, the linear illuminant 200 will be described focusing on the differences from the linear illuminant 100, and the same components as the linear illuminant 100 are designated by the same reference numerals as those of the linear illuminant 100. It is attached to 3.

As shown in FIG. 3A, in the linear illuminant 200, a plurality of particulate light reflectors 25 are dispersed and held inside the coating layer 20. Lame is mentioned as a specific example of the light reflector 25. Here, lame meant gold thread and silver thread for woven fabrics, but is now widely recognized as an expression that broadly includes substances that have been processed to reflect light, and the same applies to the present invention. Be treated. Further, in addition to lame, for example, a metal such as aluminum or nickel can be used as the light reflector 25.

When the light reflector 25 in which the coating layer 20 is dispersed is held like the linear illuminant 200, the decorativeness of the linear illuminant 200 can be improved. That is, even if the light source 10A of the linear light emitting body 200 is not emitting light, the light from the surrounding light source is reflected by the light reflecting body 25, so that the existence of the linear light emitting body 200 can be recognized. If the light source 10A emits light, a fantastic aesthetic can be obtained including the reflection of light from the light reflector 25.
As shown in FIG. 3B, the fibrous light reflector 26 can be dispersed in the coating layer 20 instead of the particulate light reflector 25.

[Third Embodiment: two linear light sources]
Next, the linear illuminant 300 according to the third embodiment of the present invention will be described with reference to FIG. In the following, the linear illuminant 300 will be described focusing on the differences from the linear illuminant 100, and the same components as the linear illuminant 100 are designated by the same reference numerals as those of the linear illuminant 100. It is attached to 4.

As shown in FIG. 4, the linear illuminant 300 is provided with two light sources 10A1 and a light source 10A2 inside the coating layer 20. The light source 10A1 and the light source 10A2 are spirally wound around each other and are wound around each other on the other side.

Both the light source 10A1 and the light source 10A2 can be turned on at the same time, or can be turned on alternately. Alternate lighting means that when the lighting time of the light source 10A1 reaches T, the lighting of the light source 10A1 is stopped and the light source 10A2 which has not been lit until then is turned on. Then, when the lighting time of the light source 10A2 reaches T, the lighting of the light source 10A2 is stopped and the light source 10A1 which has not been lit until then is turned on. By repeating the above operation, the life of the linear light emitter 100 can be extended as compared with lighting the light source 10A1 and the light source 10A2 at the same time.

It is also possible to turn on only the light source 10A1 and turn on the light source 10A2 which has not been turned on until the end of the life of the light source 10A1. This also makes it possible to extend the life of the linear light emitter 100 as compared with turning on the light source 10A1 and the light source 10A2 at the same time.

When the light reflector 25 in which the coating layer 20 is dispersed is held like the linear illuminant 300, the decorativeness of the linear illuminant 300 can be improved. That is, even if the light source 10 of the linear illuminant 300 is not emitting light, the light from the surrounding light source is reflected by the light reflector 25, so that the existence of the linear illuminant 300 can be recognized. If the light source 10 emits light, a fantastic aesthetic can be obtained including the reflection of light from the light reflector 25.

The light source 10A1 and the light source 10A2 of the linear illuminant 300 are spirally wound around each other and are wound around each other on the other side. Therefore, the light source 10A1 and the light source 10A2 are not hidden behind each other and cannot be seen, and can be recognized from the entire periphery of the curl portion 3.

[Fourth Embodiment: Band-shaped light source]
Next, the linear illuminant 400 according to the fourth embodiment of the present invention will be described with reference to FIG.
The light sources 10, 10A and 10A2 of the first to third embodiments are linear in themselves, but the linear illuminant 400 is different from this. That is, as the linear illuminant 400, a light source 10B having a planar shape is used. In the following, the linear illuminant 400 will be described focusing on the differences from the linear illuminant 100, and the same components as the linear illuminant 100 are designated by the same reference numerals as those of the linear illuminant 100 in FIG. It is attached.

As shown in FIGS. 5A and 5B, the linear illuminant 400 includes a core material 7 from the center side, a band-shaped or tape-shaped light source 10B spirally wound around the core material 7. A coating layer 20 that covers the periphery of the light source 10B is provided. The wound light source 10B constitutes the light emitting layer 11. In the linear light emitter 400, the light source 10B is a planar light source, but by being wound around the core material 7, it constitutes a linear light source in appearance. That is, if it is linear in appearance, it constitutes the linear light source in the present invention.

As the core material 7, high-tensile fibers, metal wires, and the like that can impart particularly tensile strength to the linear illuminant 400 can be used. As the high-strength fiber, a wire rod made of an aromatic polyamide-based resin can be used.
The core material 7 can be composed of a single wire rod as shown in FIG. 5 (b), and can also be composed of a plurality of wire rods having a small wire diameter as shown in FIG. 5 (c).

The light source 10B is composed of a strip-shaped inorganic EL. Since the structure of this inorganic EL is well known, to briefly show it, a sealing layer, a transparent electrode layer, a light emitting layer, an insulating layer, and a back surface provided from the front surface side to the back surface side. It includes an electrode layer and a sealing layer. Further, like the linear inorganic EL, the light source 10B is also connected to the inverter and emits light under the control of the inverter.
The width of the band-shaped light source 10B is arbitrary, but if it is too wide, it becomes difficult to wind it, and if it is too narrow, the number of times of winding increases. Therefore, it is advisable to determine the width of the light source 10B in consideration of this point.

Since the linear light source 400 has a planar light source 10B wound around the core material 7, the core material 7 can bear the tensile strength of the linear light emitter 400. Therefore, as shown in FIG. 6, when the linear illuminant 400 is stretched in a straight line and used, the heavy object 40 can be suspended.

[Fifth Embodiment: Including a plurality of conductive wires]
Next, the linear illuminant 500 according to the fifth embodiment of the present invention will be described with reference to FIG. 7.
The linear illuminant 500 according to the fifth embodiment is common to the linear illuminant 400 in that a planar light source 10B is used, but the linear illuminant 500 has a plurality of linear illuminants 500 instead of the high-strength core material 7. Here, four conductive wires 8 are provided. In the following, the linear illuminant 500 will be described focusing on the differences from the linear illuminant 400, and the same components as the linear illuminant 400 are designated by the same reference numerals as those of the linear illuminant 400 in FIG. It is attached.

As shown in FIG. 7, the linear light source 500 includes four conductive wires 8 from the center side, an insulating band 9 spirally wound around the four conductive wires 8, and a periphery of the insulating band 9. A light source 10B that is spirally wound and a coating layer 20 that covers the periphery of the light source 10B are provided.

Each of the conductive wires 8 includes a core wire 8A made of a copper alloy or the like, and an insulating coating 8B provided around the core wire 8A. Insulation here means electrical insulation. The conductive wire 8 is used to transmit an electric signal, but can also be used to transmit electric power. The four conductive wires 8 may be spirally wound and wound around each other, or may be wired in parallel with each other.

The insulating band 9 is used to bundle the four conductive wires 8. For the insulating band 9, for example, an insulating material such as strip-shaped paper or resin can be used.

According to the linear illuminant 500, the light source 10B is wound around the plurality of conductive wires 8 and further covered with a transparent coating layer 20 around the light source 10B. As a result, even if the linear light emitter 500 includes four or more conductive wires 8, if the light source 10B is made to emit light, the light emission is not blocked and the aesthetic appearance due to the light emission is not impaired.

[Sixth Embodiment: Multi-layered light source]
Next, the linear illuminant 600 according to the sixth embodiment of the present invention will be described with reference to FIGS. 8 and 9.
The linear illuminant 600 according to the sixth embodiment is common to the linear illuminants 400 and 600 in that a planar light source 10B is used, but the linear illuminant 600 has a light emitting layer around which the light source 10B is wound inside. And are provided over the outer two layers. In the following, the linear illuminant 600 will be described focusing on the differences from the linear illuminant 500, and the same components as the linear illuminant 500 are designated by the same reference numerals as those of the linear illuminant 500 in FIG. It is attached to FIG.

As shown in FIG. 8, the linear light emitting body 600 includes four conductive wires 8 from the center side, an insulating band 9 spirally wound around the four conductive wires 8, and a periphery of the insulating band 9. A first light emitting layer 13 composed of a light source 10B wound in a spiral shape and a first coating layer 20A covering the periphery of the first light emitting layer 13 are provided. The configuration up to this point is the same as that of the linear light emitting body 500, but the linear light emitting body 600 has a second light emitting layer 15 composed of a light source 10C spirally wound around the first coating layer 20A and a second light emitting layer. A second coating layer 20B that covers the periphery of the 15 is further provided. The thickness of the second coating layer 20B is preferably set to be thinner than that of the first coating layer 20A.

The linear light emitting body 600 includes a second light emitting layer 15 arranged on the outer side in the radial direction and a first light emitting layer 13 arranged on the inner side in the radial direction, and emits light from the second light emitting layer 15 until the end of its life. Let me. When the life of the second light emitting layer 15 has expired, the first light emitting layer 13 is then made to emit light. However, if the second light emitting layer 15 exists as it is, the light emitted from the first light emitting layer 13 leaks to the outside and is hindered from being visually recognized. Therefore, when the life of the second light emitting layer 15 has expired, the second light emitting layer 15 and the second coating layer 20B are peeled off. The means for peeling the second coating layer 20B is arbitrary, and for example, there is a peeling string 27 described below.

The peeling string 27 is held by the second covering layer 20B over the entire area in the axial direction thereof. The peeling string 27 is preferably provided so as to be in contact with the outer peripheral surface of the first coating layer 20A. The peeling string 27 may be exposed from the outer peripheral surface of the second coating layer 20B, or may be embedded inside in the radial direction from the outer peripheral surface.

When the life of the second light emitting layer 15 has expired, as shown in FIGS. 9A and 9B, the peeling string 27 is pulled so as to come out of the second covering layer 20B. Subsequent to FIG. 9B, if the peeling string 27 is pulled to the end, the second covering layer 20B is provided with a notch at the position where the peeling string 27 is held. The second coating layer 20B is peeled off from the linear illuminant 600 using this notch as a trigger. If the second coating layer 20B is peeled off, the second light emitting layer 15 is exposed. Therefore, the winding is unwound to peel off the light source 10B constituting the second light emitting layer 15. Now that the first coating layer 20A is exposed, the light source 10B constituting the first coating layer 20A is made to emit light. In this way, the linear illuminant 600 can have twice the life.

The peeling string 27 needs to have the strength and dimensions necessary for cutting the second coating layer 20B. As a material that can withstand this, the high-strength material used for the core material 7 can be used.

[Application example]
Next, specific uses of the linear illuminants 100 to 600 according to the present embodiment will be illustrated.
As shown in FIG. 10A, the linear illuminant 100 can be attached between the pair of partition poles 31, 31. In the conventional products currently on the market, the ratio of the ropes and chains attached between the partition poles 31 and 31 that can widen the distance between the partition poles 31 and 31 is small. On the other hand, if the linear illuminants 100 to 600 are used, they can be stretched about 3 to 5 times as much as in the no-load state, so that the intervals between the partition poles 31 and 31 can be widened to the same extent. can.

Further, in the conventional product, the tape and rope provided between the partition poles 31 and 31 are difficult to see in a dark area such as at night. On the other hand, if the linear illuminants 100 to 600 are emitted, they can be easily visually recognized even from a certain distance by emitting light at night.
Although the light emission can be performed manually, it is possible to call for more attention by emitting the linear light emitters 100 to 600 in conjunction with a motion sensor or the like in an off-limits place.

Further, by combining electric wires, for example, it is possible to combine a lamp, a neon sign, etc. on the upper part of the pole, and it can be used for a wide range of purposes.
Further, as shown in FIG. 10B, for example, a solar cell 32 can be mounted on one of the partition poles 31, and the power source of the linear illuminants 100 to 600 can be obtained from the solar cell 32. Then, the equipment will be environmentally friendly. In addition, since it does not require a power cable, etc., it can be installed anywhere.

In the following application example, as shown in FIG. 11, if the linear illuminants 100 to 600 are used as the leads of the luminaire 33, the lead portion can also emit light. Then, the decorativeness of the lighting fixture 33 can be improved.
At this time, if a cord reel wire or an elastic rubber-like string is passed through the center of the curl portion 3, the curl portion 3 will stop at a certain length. If they are attached to a heavy object, the curl cord will not stretch completely and no load will be applied to the illuminant.

The partition pole 31 and the lighting fixture 33 are examples of applications of the linear illuminants 100 to 600, and other than this, a door opening / closing part, a hanging playset, a radio microphone, a teaching pendant, various remote controls, a vocal microphone, a musical instrument shield, and an interior. Linear illuminants 100 to 600 can be used as elements such as decoration.

Further, as shown in FIG. 12A, by attaching the connectors 35 and 35 to both terminals of the linear illuminants 100 to 600, the linear illuminants 100 to 600 can be connected to each other or to other devices. It can be easily attached and detached. If the inverter and other boards are stored in the connectors 35 and 35, the appearance can be maintained. As shown in FIG. 12B, if one high-power inverter can be secured by attaching the connectors 35 and 35 to both terminals, a plurality of linear light emitters 100 to 600 can be connected.
If you pass a cord reel wire or elastic rubber string through the center of the curl cord, it will stop at a certain length. If they are attached to a heavy object, the curl cord will not stretch completely and no load will be applied to the illuminant.
In addition to the above, as long as the gist of the present invention is not deviated, the configurations listed in the above embodiments can be selected or changed to other configurations as appropriate.
