Description

  The present invention relates to a light emitting body used for, for example, marking during charging of a high voltage part.

In the cubicle (high voltage receiving / transforming equipment), there is a portion where a high voltage charging part is exposed. A skilled engineer can immediately determine the position of a dangerous charging unit, but a general person or a young engineer has a low awareness of the charging unit, so there is a risk of accidental approach to the charging unit and an electric shock.
JP 2004-164855 A

  Even if it is a general person or a young engineer who has no experience or technical ability, if the charged part is marked at a high voltage or in the immediate vicinity of the charged part, it is possible to visually recognize the sign. It is considered that the charging part is not intentionally approached. However, there is no means for directly acquiring information from the charging unit and indicating information during charging / power failure of the exposed charging unit. Note that Patent Document 1 discloses an electroluminescent element having increased light emission sensitivity.

  The present invention has been made in view of the above problems, and its main purpose is to easily confirm the state of charge of the high voltage section.

Invention for solving the previous SL problem, an inorganic EL material forming a plurality of light-emitting particles, a first dielectric material dispersed supporting the plurality of light emitting particles, to facilitate emitting the plurality of light emitting particles A second dielectric material having a dielectric constant greater than the dielectric constant of the first dielectric material, and the plurality of dielectric particles are dispersedly supported around the first dielectric material. A third dielectric material having a dielectric constant smaller than the dielectric constant of the second dielectric material; a light-transmitting conductive layer laminated on the dielectric material; and a conductive antenna connected to the conductive layer; And a light emitter provided adjacent to an object that generates the induction electric field so as to emit light under the induction electric field.

According to this light emitter, the induced electric field in the place where it is installed and the polarization charge generated in the first dielectric material, the plurality of dielectric particles made of the second dielectric material, and the third dielectric material by this induced electric field. A plurality of light-emitting particles made of an inorganic EL material emit light under an electric field that is combined with an electric field that is further formed at the place where the device is installed. This light is transmitted through the first dielectric material and the third dielectric material and is emitted to the outside of the light emitter. Since this luminous body uses the induction electric field generated by the object as the only source of electric energy, it is not necessary to prepare a separate power source. In addition, the first dielectric material and the third dielectric material have a dielectric constant smaller than that of the second dielectric material, but may have higher light transmittance than the second dielectric material. On the other hand, since the second dielectric material has a higher dielectric constant than the first dielectric material and the third dielectric material, the electric field formed by the polarization charge can be higher. Therefore, if the light transmission function is mainly given to the first dielectric material and the third dielectric material, and the electric field concentration function at the place where the light is installed is mainly given to the second dielectric material, the transparency to the visible light and the electric field The first dielectric material, the second dielectric material, and the third dielectric material can be selected so as to increase the degree of concentration. Therefore, the light emitter can maintain a predetermined light amount. As described above, the light emitter does not require a power source, but can maintain a predetermined light amount. Further, the structure of this luminescent material is such that the first dielectric material that supports and disperses a plurality of luminescent particles is mainly coated with the third dielectric material, so that these luminescent particles are missing from the luminescent material. In addition to being suppressed, it also has a function of moisture-proofing these luminescent particles. Therefore, the predetermined light amount maintenance period becomes longer.
Further, according to this light emitter, when installed in a place where an induction electric field is generated, the conductive antenna effectively collects the induction electric field, and the electric field guided to the connected conductive layer is a dielectric material. A high electric field can be applied. In addition, light emission of the inorganic EL material can be visually recognized from the light-transmitting conductive layer, and the spread of the sign and the meaning of the message can be easily recognized.

In the light emitter, the first dielectric material and the third dielectric material are preferably the same type of material.
The same species has the same chemical structure, or is basically similar, for example, as in the relationship between a homopolymer and a copolymer containing a small amount of a copolymer component. means. According to this light emitter, since the third dielectric material around the first dielectric material is difficult to peel off, the light emitting particles are hardly exposed to the outside. Therefore, the maintenance period of the predetermined light amount becomes longer and the durability period of the light emitter becomes longer.

Moreover, it is preferable that this light-emitting body further includes a moisture-proof material that covers the periphery of each of the light-emitting particles.
According to this luminescent material, the inorganic EL material forming the luminescent particles is hardly exposed to moisture, so that it is difficult to be altered. Therefore, the maintenance period of the predetermined light amount becomes longer and the durability period of the light emitter becomes longer.

Further, in the light emitter, the plurality of light emitting particles may be made of the inorganic EL material that emits light at a plurality of wavelengths.
According to this illuminant, if a plurality of luminescent particles are formed from an inorganic EL material containing, for example, three types of inorganic EL materials that emit red (R), green (G), and blue (B) in a predetermined ratio. The illuminant can emit light in any luminescent color. Alternatively, for example, if light emitting particles made of a single inorganic EL material that emits light for each of the RGB are mixed and dispersed at a predetermined ratio, the light emitter can emit light in any light emission color. Also, various light emission colors can be realized by combining any two of the RGB at a predetermined ratio.

Moreover, it is preferable that this light-emitting body is processed into a sheet shape.
According to this light emitter, it is possible to install an object that generates an induction electric field such that a part of the object is colored with a plurality of light emitting particles. Therefore, a part of the object on which the light emitter is installed appears to emit light while maintaining a predetermined amount of light.

Further, in this light emitter, the object may be a bus of a cubicle on which the light emitter is installed.
According to this light-emitting body, the light-emitting body emits light by using an induction electric field generated around the cubicle bus, for example, by an alternating current. In this way, the light emitter can use an induction electric field accompanying the power originally supplied by the cubicle as a power source, and therefore does not require a separate power source. If this illuminant is installed on the bus bar of a cubicle and used, for example, as an indicator lamp in a charged state, this indicator lamp does not require a power source, while maintaining a predetermined amount of light around the cubicle. It will emit light. Therefore, for example, the installation cost and maintenance cost of the indicator lamp can be reduced.

  In addition, the problems disclosed in the present application and the solutions thereof will be clarified by the column of the best mode for carrying out the invention and the drawings.

  According to the present invention, the state of charge of the high voltage unit can be easily confirmed.

=== Outline of luminous body ===
The luminous body of the present embodiment includes an inorganic EL material and a dielectric material that disperses and supports the inorganic EL material therein, and is provided, for example, adjacent to a bus bar of a cubicle. The outline of the inorganic EL material and dielectric material of the present embodiment will be described below.

<<< Inorganic EL material >>>
The inorganic EL material of the present embodiment is a so-called intrinsic EL material, and emits light by applying an alternating electric field or the like (electroluminescence). The principle of this electroluminescence is as follows.

First, electrons in the interface between the dielectric material and the inorganic EL material or in the inorganic EL material in the vicinity of the dielectric material are accelerated by an electric field (hot electrons) to excite the electrons at the emission center in the inorganic EL material. This mechanism is as disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-116503 or International Application Publication No. 02/080626.
Next, this emission center emits as light the difference in energy when electrons in the excited state return to the ground state.

  This inorganic EL material is, for example, a substance in which copper and chlorine are added as luminescent centers to zinc sulfide (ZnS: Cu, Cl), and a substance in which copper and aluminum are added as luminescent centers to zinc sulfide (ZnS: Cu). , Al), a material made of zinc sulfide (ZnS: Cu, Mn, Cl) and the like with zinc, manganese, and chlorine added as a luminescent center.

Alternatively, the inorganic EL material of the present embodiment includes, for example, (1) as a red light emitter, (Zn, Mg) S: Mn, CaS: Eu, ZnS: Sm, F, Ga ₂ O ₃ : Cr, MgGa ₂ O ₄ : Eu, (2) As a green light emitter, (Zn, Mg) S: Mn, ZnS: Tb, F, Ga ₂ O ₃ : Mn, Zn ₂ SiO ₄ : Mn, (3) Blue The light emitter may be BaAl ₂ S ₄ : Eu, CaS: Pb, SrS: Ce, SrS: Cu, CaGa ₂ S ₄ : Ce, CaAl ₂ O ₄ : Eu, or the like.

  The inorganic EL particles 20 described later may be particles made of an inorganic EL material containing, for example, three types of inorganic EL materials that emit red (R), green (G), and blue (B) at a predetermined ratio. . Alternatively, the inorganic EL particles 20 to be described later include, for example, inorganic EL particles that emit red (R), inorganic EL particles that emit green (G), and inorganic EL particles that emit blue (B). Particles mixed at a ratio may be used. Further, in the above two cases, any two of RGB may be combined at a predetermined ratio. By adjusting this predetermined ratio, various emission colors can be realized.

<<< Dielectric material >>>
The dielectric material of the present embodiment is, for example, an organic polymer material. The organic polymer material is preferably a resin that easily transmits the light emitted from the inorganic EL material, that is, transparent to visible light. Examples thereof include polyamide resins, polyester resins, fluorine resins, and polyolefin resins. The organic polymer material is preferably a material having moisture resistance (for example, a fluorine-based resin) against an inorganic EL material that may be altered by moisture. The organic polymer material preferably has a higher dielectric constant so that a higher electric field can be applied. The higher the electric field applied to the inorganic EL material dispersed and supported by the organic polymer material, the higher the amount of light of the inorganic EL material, for example, because the energy of hot electrons described above increases.

  Examples of the polyamide-based resin include half polyamides formed from aliphatic polyamides such as nylon 6 (registered trademark), nylon 66 (registered trademark), nylon 12 (registered trademark), copolymers thereof, aromatic diamines, and dicarboxylic acids. Aromatic polyamides and copolymers thereof are mentioned.

  Examples of polyester resins include terephthalic acid, isophthalic acid, naphthalene 2,6 dicarboxylic acid, phthalic acid, α, β- (4-carboxyphenoxy) ethane, 4,4′-dicarboxyphenyl, 5-sodium sulfoisophthalate. Aromatic dicarboxylic acids such as acids can be mentioned. Examples of the polyester resin include aliphatic dicarboxylic acids such as adipic acid and sebacic acid or esters thereof, ethylene glycol, diethylene glycol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, Examples thereof include polyesters obtained by polycondensation with diol compounds such as cyclohexane-1,4-dimethanol, polyethylene glycol, and tetramethylene glycol, and copolymers thereof.

  Examples of the fluororesin include polyvinylidene fluoride (PVDF), polytetrafluoroethylene, polymonochlorotrifluoroethylene, polyhexafluoropropylene, and copolymers thereof.

  Examples of the polyolefin resin include polyethylene, polypropylene, poly-4-methyl-1-pentene, and the like.

=== Configuration Example of Luminescent Body ===
Hereinafter, a configuration example of the light emitter of the present embodiment will be described with reference to the drawings. In addition, the light-emitting body of this Embodiment shall be fiber form or sheet form.

<<<< first embodiment >>>>
As illustrated in FIG. 1A, the light emitter 10 of the first embodiment is a dielectric fiber (dielectric material) 30 made of, for example, polyvinylidene fluoride (PVDF), for example, having a width of 8 mm and a thickness of 2 mm. However, for example, inorganic EL particles (inorganic EL material, luminescent particles) 20 having a central particle diameter of 20 μm made of zinc sulfide (ZnS: Cu) to which copper is added are uniformly dispersed and supported at a weight ratio of 20 wt%.

  FIG. 1A is a cross-sectional view taken along a plane (XY plane) perpendicular to the fiber axis (Z axis) direction of the light emitter 10 according to the first embodiment. Further, the surface of the inorganic EL particles 20 of the first embodiment is provided with a boehmite (AlO (OH)) coating (moisture-proof material) 20a for moisture-proofing the surface. Thereby, since the inorganic EL particles 20 are not easily exposed to moisture, the inorganic EL particles 20 are hardly deteriorated. Therefore, the sustaining period of the predetermined light amount from the light emitter 10 becomes longer, and the durability period of the light emitter 10 becomes longer.

  The weight ratio of the inorganic EL particles 20 described above is not limited to 20% by weight, and may be, for example, 5% by weight to 50% by weight. If the weight ratio is smaller than 5% by weight, the light from the light emitter 10 does not reach a predetermined light amount. Therefore, the light emitted from the marker lamp when the light emitter 10 is, for example, a high-voltage charged lamp. The brightness cannot reach a level that is visible from a long distance. On the other hand, if the weight ratio is greater than 50% by weight, the fiber strength of the light emitter 10 may be reduced. In general, since the inorganic EL material is expensive, the manufacturing cost of the light emitter 10 increases as the weight ratio of the inorganic EL particles 20 increases. Therefore, by setting the weight ratio of the inorganic EL particles 20 to 5% by weight to 50% by weight, for example, a marker lamp having high emission luminance and durability and low manufacturing cost can be realized.

  The center particle diameter of the inorganic EL particles 20 described above is not limited to 20 μm, and may be, for example, 0.01 μm to several hundred μm. However, the smaller the central particle size of the inorganic EL particles 20 is, the smaller the amount of light emitted from the light emitter 10 is. On the other hand, the larger the center particle size is, the more difficult it is to process the light emitter 10 into a fiber. The center particle size is preferably 0.1 μm to several hundred μm.

<<< Second Embodiment >>>
As illustrated in FIG. 1B, the light emitter 11 according to the second embodiment includes, for example, zinc sulfide (ZnS: Cu) in which a dielectric fiber 31 having a width of 8 mm and a thickness of 2 mm is added with, for example, copper. The inorganic EL particles (inorganic EL material, luminescent particles) 20 having a central particle diameter of 20 μm are uniformly dispersed and supported at a weight ratio of 20% by weight. The dielectric fiber 31 is made of, for example, a dielectric fiber (second dielectric material) 30 made of polyvinylidene fluoride (PVDF) and a high dielectric particle (center diameter of 1 μm, for example) made of barium titanate (BaTiO ₃ ) ( (First dielectric material, dielectric particles) 40 is dispersed and supported at a weight ratio of 20% by weight.

  FIG. 1B is a cross-sectional view taken along a plane (XY plane) perpendicular to the fiber axis (Z-axis) direction of the light emitter 11 according to the second embodiment. Further, a boehmite (AlO (OH)) coating 20a is applied to the surface of the inorganic EL particles 20 of the second embodiment to prevent moisture on the surface.

  If the dielectric constant of the high dielectric particle 40 is ε1 and the dielectric constant of the dielectric fiber 30 is ε2, the average dielectric constant of the dielectric fiber 31 can take a value between ε1 and ε2 (provided that ε1> ε2). Accordingly, the dielectric fiber 30 is made of a material having a relatively high light transmittance even if the dielectric constant is relatively small, while the high dielectric particle 40 is made to have a relatively low light transmittance even if the dielectric constant is relatively small. However, if a material having a relatively large dielectric constant is used, the combined dielectric fiber 31 can have a predetermined transparency with respect to visible light and a material having a predetermined dielectric constant. As the transparency of the dielectric fiber 31 is higher, visible light from the inorganic EL particles 20 dispersed and supported by the dielectric fiber 31 is more easily transmitted. On the other hand, the higher the dielectric constant of the dielectric fiber 31, the higher the concentration of the electric field with respect to the inorganic EL particles 20 that are dispersed and supported by the dielectric fiber 31, and thus the amount of light from the inorganic EL particles 20 under this electric field increases.

  The weight ratio of the inorganic EL particles 20 described above is not limited to 20% by weight, and may be, for example, 5% by weight to 50% by weight for the same reason as in the first embodiment.

  The weight ratio of the high dielectric particles 40 described above is not limited to 20% by weight, and may be, for example, 5% by weight to 50% by weight. If the weight ratio is smaller than 5% by weight, the concentration of the electric field on the inorganic EL particles 20 does not increase, and thus the light from the light emitter 11 may not reach a predetermined light amount. On the other hand, if the weight ratio is larger than 50% by weight, the fiber strength of the illuminant 11 is decreased and the ratio of the high dielectric particles 40 that are opaque to visible light is increased. May become opaque. In general, since a high dielectric material is expensive, the manufacturing cost of the light emitter 11 increases as the weight ratio of the high dielectric particles 40 increases.

  From the above, by setting the weight ratio of the inorganic EL particles 20 and the high dielectric particles 40 to 5% by weight to 50% by weight, for example, it is possible to realize a marker lamp with high emission luminance and durability and low manufacturing cost. Furthermore, the total weight ratio of the inorganic EL particles 20 and the high dielectric particles 40 is preferably 10% by weight to 50% by weight. Thereby, it is possible to realize a marker lamp having higher emission luminance and durability and lower manufacturing cost.

  The center particle diameter of the inorganic EL particles 20 described above is not limited to 20 μm, and may be, for example, 0.01 μm to several hundred μm for the same reason as in the first embodiment.

The high dielectric particles 40 described above are not limited to barium titanate (BaTiO ₃ ), and may be any organic material or inorganic material as long as the dielectric constant is relatively high. As the organic material, for example, cyanoethyl cellulose is preferable, and as the other inorganic material, for example, SrTiO ₃ , TiO ₂ , Al ₂ O ₃ , and Si ₃ N ₄ are preferable.

<<< Third Embodiment >>>
As illustrated in FIG. 2, the light emitter 12 of the third embodiment includes a core portion and a sheath portion. This figure is a cross-sectional view taken along a plane (XY plane) perpendicular to the fiber axis (Z-axis) direction of the light emitter 12 of the third embodiment.

  The core is made of, for example, polyvinylidene fluoride (PVDF), for example, 6 mm wide and 1 mm thick dielectric fiber (first dielectric material) 30a, for example, a central grain made of zinc sulfide (ZnS: Cu) to which copper is added. Inorganic EL particles (inorganic EL material, luminescent particles) 20 having a diameter of 20 μm are uniformly dispersed and supported at a weight ratio of 20% by weight.

The sheath part forms a coating layer on the outer peripheral surface of the core part, and has a width of 8 mm and a thickness of 2 mm. For example, a dielectric fiber (third dielectric material) 30b made of polyvinylidene fluoride (PVDF) is titanic acid. For example, high dielectric particles (second dielectric material, dielectric particles) 40 made of barium (BaTiO ₃ ) and having a center particle diameter of 1 μm are dispersed and supported at a weight ratio of 20% by weight.

  In the third embodiment, the dielectric fibers 30a and 30b forming the core portion and the sheath portion are the same type of polyvinylidene fluoride (PVDF). Homogeneous means that the chemical structure is exactly the same, or is basically similar, such as the relationship between a homopolymer and a copolymer containing a small amount of a copolymer component. To do. By being the same kind, the separation at the interface between the core and the sheath is suppressed, and the dielectric fiber 30b around the dielectric fiber 30a is difficult to peel off. It is difficult to expose to the outside (see, for example, JP-A-2001-131829). Therefore, the maintenance period of the predetermined light amount becomes longer and the durability period of the light emitter 12 becomes longer. However, it is not limited to the same type, and the dielectric fibers 30a and 30b forming the core portion and the sheath portion may be made of different organic polymer materials. In this case, for example, if a dielectric fiber having higher transparency than the core is used for the sheath, the amount of light from the light emitter 12 is increased.

  Note that a boehmite (AlO (OH)) coating 20a is applied to the surface of the inorganic EL particles 20 of the third embodiment to prevent moisture on the surface.

  If the dielectric constant of the high dielectric particle 40 is ε1 and the dielectric constant of the dielectric fibers 30a and 30b is ε2, the average dielectric constant of the dielectric fiber 32 can take a value between ε1 and ε2 (however, ε1> ε2). Accordingly, the dielectric fibers 30a and 30b are made of a material having a relatively high light transmittance even if the dielectric constant is relatively small, while the high dielectric particles 40 are relatively light-transmissive. If the material has a relatively large dielectric constant even if it is low, the combined dielectric fiber 32 can have a predetermined transparency with respect to visible light and a material having a predetermined dielectric constant. As the transparency of the dielectric fiber 32 is higher, visible light from the inorganic EL particles 20 dispersed and supported by the dielectric fiber 32 is more easily transmitted. On the other hand, the greater the dielectric constant of the dielectric fiber 32, the higher the concentration of the electric field with respect to the inorganic EL particles 20 that are dispersed and supported by the dielectric fiber 32, and thus the amount of light from the inorganic EL particles 20 under this electric field increases.

  The structure of the luminous body 12 of the third embodiment is such that the dielectric fiber 30a that disperses and supports the inorganic EL particles 20 is mainly covered with the dielectric fiber 30b. In addition to suppressing the loss, the inorganic EL particles 20 have a function of preventing moisture. Therefore, the predetermined light amount maintenance period becomes longer.

  The weight ratio of the inorganic EL particles 20 described above is not limited to 20% by weight, and may be, for example, 5% by weight to 50% by weight for the same reason as in the first and second embodiments. Further, the weight ratio of the high dielectric particles 40 described above is not limited to 20% by weight, and may be, for example, 5% by weight to 50% by weight for the same reason as in the second embodiment. . Thereby, for example, a marker lamp having high emission luminance and durability and low manufacturing cost can be realized.

  The center particle diameter of the inorganic EL particles 20 described above is not limited to 20 μm, and may be, for example, 0.01 μm to several hundred μm for the same reason as in the first and second embodiments.

The above-described high dielectric particles 40 are not limited to barium titanate (BaTiO ₃ ), and may be, for example, cyanoethyl cellulose (organic material), SrTiO ₃ , TiO as long as the dielectric constant is relatively high. ₂ , Al ₂ O ₃ , Si ₃ N ₄ (above, inorganic material) or the like may be used.

<<< Fourth embodiment >>>>
As illustrated in FIG. 3, the light emitter 100 according to the fourth embodiment includes a light emitter 15 described below, for example, two polypropylenes having a thickness of 50 μm (Y-axis direction) and a width of 20 mm (X-axis direction). It is sandwiched between sheets (dielectric material) 60 to form a sheet shape. This figure is a cross-sectional view taken along a plane (XY plane) perpendicular to the length (Z-axis) direction of the light emitter 100 according to the fourth embodiment.

  The light emitter 15 is made of, for example, zinc sulfide (ZnS: Cu) to which copper is added, for example, a binder (dielectric material) 35 made of acrylic resin and having a thickness of 40 μm (Y-axis direction) and a width of 10 mm (X-axis direction). The inorganic EL particles (inorganic EL material, luminescent particles) 20 having a center particle diameter of 20 μm are uniformly dispersed and supported at a weight ratio of 50% by weight.

  The weight ratio of the inorganic EL particles 20 to the luminous body 15 described above is not limited to 50% by weight, and may be, for example, 5% by weight to 80% by weight. If the weight ratio is less than 5% by weight, the light from the light emitter 15 does not reach a predetermined light amount, and therefore the light emitted from the indicator lamp when the light emitter 100 is, for example, a high-voltage charging indicator lamp. The brightness cannot reach a level that is visible from a long distance. On the other hand, if the weight ratio is larger than 80% by weight, it is difficult to uniformly disperse the inorganic EL particles 20 in the binder 35, and the viscosity becomes too high and the coating property is lowered. Moreover, there exists a possibility that the intensity | strength of the light-emitting body 15 may fall. In general, since the inorganic EL material is expensive, the manufacturing cost of the light emitter 100 increases as the weight ratio of the inorganic EL particles 20 increases. Therefore, by setting the weight ratio of the inorganic EL particles 20 to 5% by weight to 80% by weight, for example, an indicator lamp having high emission luminance and durability and low manufacturing cost can be realized.

  The thickness of the polypropylene sheet 60 described above is not limited to 50 μm, and may be, for example, 20 μm to 500 μm. If it is thinner than 20 μm, the polypropylene sheet 60 tends to be damaged, whereas if it is thicker than 500 μm, the light emitter 100 tends to lose its flexibility and become difficult to process.

The light emitter 101 is attached to each conductor with an adhesive or a double-sided adhesive tape. Further, in the light emitting body 101, a transparent conductor sheet bent in an L shape (for example, made of indium tin oxide (ITO) or the like) is a front polypropylene sheet 60 (with one attached to each facility) Is provided in front of the opposite polypropylene sheet 60). The portion protruding forward of the conductor sheet is called a conductive antenna and is connected to the conductive layer, and has the effect of enhancing the electroluminescence of the inorganic EL material.

  If it is narrow like a switchgear and the charging part and the power outage part are complicated, the power outage part and the charging part may be mistaken at the time of work. By sticking the sheet-like light-emitting body 101 to such a location (conductor), the charged state of the conductor can be visually recognized, so that the charged portion and the power failure portion can be easily and reliably confirmed. According to this, it is possible to ensure and improve safety during work on the cubicle.
