Description

  The present invention relates to a figurine with an illumination light source and a method of manufacturing the same, for example, an invention is applied to a figurine with an illumination light source in which an image is formed by laser processing inside a figurine made of crystal glass and the image can be illuminated It is suitable.

  Conventionally, a technique for forming an image in a crystal glass by laser processing is known, and an ornament is manufactured using this technique. In particular, Patent Document 1 has an inclined side surface which has an image formed by laser processing inside a transparent or translucent material, is processed to have a back surface black or dark, and extends from the back surface to the front surface And figurines having a top surface are described.

  Heretofore, as a light source for illuminating the interior of such a crystal glass figurine, an LED illuminating device has been used, and this LED illuminating device has been attached to the back or bottom of the figurine.

Patent No. 5305203 specification

  However, for example, when the LED lighting device is attached to the back surface of the ornament described in Patent Document 1 and illumination is performed, even if the image is extremely high definition and high accuracy, the image can be sufficiently highlighted. It was not always easy to get a modestly high rendering effect.

  Therefore, the problem to be solved by the present invention is an illumination that can sufficiently stand out an extremely high definition and high precision image formed by laser processing inside a transparent or translucent material, and obtain an excellent stage effect. It can be done, yet the observer can not know the position of the light source, and it can produce a unique strange feeling, and a manufacturing method by which such a decoration with a light source can be easily manufactured. To provide.

  The present inventors have intensively studied to solve the above-mentioned problems, and as an illumination light source, they are fabricated to be ultra-thin as compared with a conventional general inorganic EL sheet having a thickness of 0.2 to 1 mm. Focusing on the use of the special flexible inorganic EL sheet, the inorganic EL sheet is closely attached to the top surface of the figurine of Patent Document 1 so that its thickness can not be recognized at all, and illumination is performed using this inorganic EL sheet. An extremely high-definition and high-precision image formed inside a figurine can be made to stand out sufficiently well in an unexpected manner, and a high rendering effect can be obtained, yet the position of the light source can not be determined by looking at the figurine It came to devise this invention.

That is, to solve the above problems, the present invention is
A decoration having an image formed by laser processing inside a transparent or translucent material, a back surface treated to be black or dark, and an inclined side surface and a top surface formed to extend from the back surface to the front surface;
An inorganic EL sheet having a thickness of 50 μm or less in close contact with the top surface of the above-mentioned figurine,
It is a figurine with an illumination light source characterized by having.

  In this figurine equipped with the illumination light source, the inorganic EL sheet in close contact with the top surface of the figurine serves as the illumination light source of the image. The size, shape, position, and the like of the inorganic EL sheet are selected so as to illuminate the image formed in the interior of the ornament by the light emitted in a plane from the inorganic EL sheet. The thickness of the inorganic EL sheet is preferably 30 μm or less, more preferably 20 μm or less, and further preferably 15 μm or less. The lower limit of the thickness of the inorganic EL sheet is not particularly present as long as light emission is possible, but is generally 5 μm or more, and more generally 8 μm or more. Power supply to the inorganic EL sheet can be performed by a commercial power source or a battery, and is selected as necessary. Inorganic EL sheets are generally made of a transparent substrate such as polyethylene terephthalate (PET) on which a luminescent layer containing a phosphor obtained by doping zinc sulfide (ZnS) with copper (Cu), an electrode or the like is laminated by a flexible transparent film. The outermost layer is made of a transparent film. Therefore, in this case, in detail, the transparent film of the inorganic EL sheet is in close contact with the top surface of the figurine.

  Typically, the inorganic EL sheet is attached to the top surface of the figurine so as to cover the inorganic EL sheet in a stretched state in which an electrically insulating stretchable tape or sheet is stretched. Is pressed against. The adhesive is typically applied to the surface of the tape or sheet on the inorganic EL sheet side, but not to the tape or sheet, but to the top surface of the ornament of the peripheral portion of the inorganic EL sheet You may do so. As described above, when the inorganic EL sheet is pressed against the top surface of the figurine by the tape or sheet, the flexible inorganic EL sheet adheres closely to the top surface of the figurine without any intervening air layer. The tape or sheet typically consists of rubber. The rubber may be natural rubber or synthetic rubber. As a synthetic rubber, silicone rubber is preferably used. The figurine typically consists of glass. The glass may be basically anything, for example, soda glass, crystal glass (lead glass), borosilicate glass, quartz glass and the like, but is preferably crystal glass.

Also, this invention is
A ceiling of a figurine having an image formed by laser processing inside a transparent or translucent material, a back surface processed to be black or dark, and an inclined side surface and a top surface formed to extend from the back surface to the front surface It is a manufacturing method of the object with illumination light source which has the process of making the surface adhere an inorganic EL sheet whose thickness is 50 μm or less.

  In the manufacturing method of the object with illumination light source, typically, after placing the inorganic EL sheet on the top surface of the object, the inorganic EL sheet is covered in a stretched state of the electrically insulating stretchable tape or sheet. In this way, the inorganic EL sheet is pressed against the top surface of the figurine by adhering to the top surface of the figurine. By doing this, the inorganic EL sheet can be brought into close contact with the top surface of the figurine.

  In the invention of the manufacturing method of the figurine with illumination light source, what has been described in relation to the invention of the figurine with illumination light source described above holds as long as it does not violate the nature thereof.

  According to the present invention, light emitted from the inorganic EL sheet in close contact with the top surface of the figurine in a plane and incident on the top surface of the figurine directly enters the interior of the figurine and illuminates the image formed in the interior of the figurine Do. At this time, the incident light on the surface around the figurine inside the figurine and the reflected light also contribute to the illumination of the image. For this reason, the extremely high definition and high precision image formed inside the figurine can be sufficiently highlighted, and a high stage effect can be easily obtained. Moreover, since the inorganic EL sheet as the illumination light source can not be recognized even when observing the top surface of the figurine from the outside, the observer does not know the position of the light source, and a unique strange feeling is generated. it can.

  Hereinafter, modes for carrying out the invention (hereinafter referred to as “embodiments”) will be described.

<One embodiment>
[Figurine with illumination light source]
Fig. 1 shows a figurine with an illumination light source. As shown in FIG. 1, the object with illumination light source has an image 11 formed by laser processing inside of an object 10 made of glass such as crystal glass, for example. The image 11 may be basically anything, but a star is illustrated in FIG. 1 as an example. The ornament 10 is basically the same as that disclosed in Patent Document 1. That is, the back surface of the figurine 10 is a background surface which is darkened by adhering a black member to UV (ultraviolet light), and both side surfaces and the top surface are inclined so as to spread from the back surface toward the front.

  The top surface of the figurine 10 comprises a front portion parallel to the bottom surface and a rear portion inclined with respect to the bottom surface so as to be lower from the front surface to the back surface. A rectangular inorganic EL sheet 20 having a thickness of 50 μm or less is in close contact with the top surface front portion of the figurine 10 without an air layer interposed therebetween. More specifically, the tape 30 is electrically insulating and wider than the inorganic EL sheet 20 and is adhered to the top surface of the object 10 so as to cover the entire inorganic EL sheet 20 in a stretched state. ing. Thus, since the tape 30 covers the whole of the inorganic EL sheet 20 in a stretched state, a force for shrinking constantly acts on the surface of the tape 30. For this reason, on the inorganic EL sheet 20 covered by the tape 30, a force is exerted to press the top face front of the object 10. As a result, the inorganic EL sheet 20 is in close contact with the front surface of the top surface of the object 10 without an air layer interposed therebetween. In FIG. 2, the inorganic electroluminescent sheet 20 and the tape 30 which closely_contact | adhered to the top surface front part of the ornament 10 are expanded and shown. In FIG. 2, the thicknesses of the inorganic EL sheet 20 and the tape 30 are exaggerated. The tape 30 is typically formed of rubber, such as silicone rubber.

  The wiring for feeding to the inorganic EL sheet 20 preferably uses, for example, an ultrathin flat electrode wire having a thickness of about 10 μm so as not to recognize its thickness or thickness. The power source of the inorganic EL sheet 20 can be a conventionally known one.

[Method of manufacturing figurine with illumination light source]
FIGS. 3A to 3E show an example of a method of manufacturing the figurine with illumination light source.

  As shown to FIG. 3A, the inorganic electroluminescent sheet 20 is mounted in the top-surface front part of the figurine 10. FIG. At this point of time, an air layer is usually interposed between the top surface front of the figurine 10 and the inorganic EL sheet 20.

  Next, as shown in FIG. 3B, one end of the tape 30 is adhered to a portion immediately next to one end of the inorganic EL sheet 20 at the front surface of the top surface of the ornament 10, and the tape 30 against the front surface of the top surface 10 While holding at a constant angle, a force is applied as shown by the arrows to sufficiently stretch in the longitudinal direction.

  Next, as shown in FIG. 3C, while the tape 30 is sufficiently stretched in the longitudinal direction, the inclination angle of the object 10 with respect to the top front portion of the object 10 is reduced and brought close to the top front portion. Bond to

  Next, while the tape 30 is continuously stretched in the longitudinal direction, the inclination angle of the object 10 with respect to the top front of the object 10 is further reduced, and the adhesion of the tape 30 is advanced from one end to the other. Thus, as shown in FIG. 3D, only the other end of the tape 30 is not adhered.

  Thereafter, as shown in FIG. 3F, the other end of the tape 30 is adhered to a portion immediately adjacent to the other end of the inorganic EL sheet 20.

  By the above, the object with illumination light source shown in FIG. 1 is manufactured.

As a figurine 10, a crystal glass figurine having a size of 10 cm cube is used to form an image of Himeji Castle by laser processing, and a figurine with a light source is manufactured according to the method of manufacturing a figurine with a light source described above. did. The inorganic EL sheet 20 used had a thickness of 12 μm. The tape 30 used was made of silicone rubber. This ultra-thin flat electrode wire is formed to reach the bottom via the side of the object 10, using an ultra-thin flat electrode wire with a thickness of about 10 μm as a wire for feeding to the inorganic EL sheet 20, Connected to the power supply.

  When the electricity was turned on in the room where the illumination was provided to the figurine with illumination light source thus obtained and the inorganic EL sheet 20 was made to emit light, the Himeji Castle inside the figurine 10 was illuminated and floated up clearly. From the point of view, the presence and position of the illumination light source were completely unknown.

  As described above, according to this embodiment, the inorganic EL sheet 20 having a thickness of 50 μm or less is in close contact with the front surface of the top surface of the object 10, so that the inorganic EL sheet 20 emits in a planar shape, The light incident on the front of the top surface 10 is directly incident on the interior of the figurine 10 and illuminates the image 11 formed on the interior of the figurine 10. Under the present circumstances, it injects into the surface of the periphery of the figurine 10 in the inside of the figurine 10, and the reflected light also contributes to illumination of an image. For this reason, the light emitted from the inorganic EL sheet 20 in the form of a plane is extremely high in efficiency for illumination of the image 11. By this, the extremely high definition and high precision image 11 formed inside the object 10 by laser processing can be sufficiently highlighted, and a high rendering effect can be easily obtained. Moreover, since the inorganic EL sheet 20 as the illumination light source can not be recognized even if the top surface of the figurine 10 is observed from the outside, the observer does not know the position of the light source and causes a unique strange feeling. be able to. From the above, the value of the figurine 10 can be dramatically increased.

  As mentioned above, although one embodiment of this invention was described concretely, this invention is not limited to the above-mentioned embodiment, A various deformation | transformation based on the technical idea of this invention is possible.

  For example, the numerical values, configurations, shapes, materials, methods, and the like described in the above embodiments are merely examples, and different numerical values, configurations, shapes, materials, methods, and the like may be used as necessary.
