Description

  The present invention relates to a luminous ornament applied to a wristwatch, a portable electronic device, various instruments, and the like, and relates to a luminous ornament capable of visually recognizing a display portion in a dark place at night using a luminous member.

  For example, in a wristwatch that uses a pointer, a luminous member (hereinafter referred to as a “nocturnal member”) is used on a dial and part of the pointer so that the time can be visually recognized even in a dark place at night (hereinafter referred to as “dark place”). The phosphorescent part is formed by a method such as printing or affixing in a sheet form, and energy is stored in the phosphorescent part by external light in a bright place in the daytime (hereinafter referred to as “light place”) It is known that it can store and recognize the time by causing the phosphorescent part to emit light in the dark at night.

  In such a wristwatch, the time can be known by the light emission of the phosphorescent part in the dark place, but in the bright place, the luminous member formed on the dial or the pointer looks like a specific white-green color, and the decorative property This problem is lacking, and this improvement has been desired. This is because the wristwatch not only serves as a device for notifying the time but also serves as a decorative item.

  Conventionally, for example, a pointer-type wristwatch is used as an example to devise the area and arrangement of the luminous member so that the time is known so that the luminous member is not conspicuous in a bright place. Then, a proposal has been made in which a light-emitting element is used to emit light from a luminous member to illuminate a display unit so as to know the time. (For example, refer to Patent Document 1).

  In the prior art disclosed in Patent Document 1, a dial plate made of a metal plate in which a large number of fine through holes are formed, a luminous member filled in the through holes, and a luminous member on the back side of the dial plate are made to emit light. In the dark, the luminous member emits light by illuminating the dial plate to illuminate the dial so that the time can be read.

  By adopting such a configuration, the entire dial can emit light at a desired time in a dark place, and the time can be read. I am doing so.

Japanese Patent Laid-Open No. 2003-248445 (first page, FIG. 1)

  In the prior art shown in Patent Document 1, a large number of fine through holes with steps are formed in a dial using a metal plate such as stainless steel, and a luminous member is filled in each through hole, and on the back side of the dial A light guide plate is arranged, and ultraviolet light emitted from the light emitting element emits a number of luminous members formed in each through-hole as a backlight via the light guide plate, so that the display portion side of the dial plate The whole is lit to know the time.

However, in the prior art disclosed in Patent Document 1, a large number of through holes are arranged in a wide area of the dial plate, and the diameter of each through hole is smaller than the thickness of the metal plate (for example, about 0.1 mm) so as not to stand out. However, it is not easy to make the entire thin dial plate having a large number of through holes a high-grade decorative surface having a gloss like a mirror surface. For example, it is possible to obtain a gloss like a mirror surface by providing a process such as polishing, but it is expensive due to the increase in the number of processes, and the glossy surface in the assembly process until the windshield glass of the watch is incorporated and the display part is protected There is also a problem that it is easily scratched.

  In addition, the prior art uses the electrical energy of a wristwatch battery or the like to illuminate the light emitting element for illumination to illuminate the entire display portion side of the dial so that the time is known. It does not use external light. Therefore, it is not related to the effective arrangement of the luminous member for efficiently taking in external light and storing it.

  In addition, a nocturnal member is incorporated into a decorative member made of precious metal, etc., and has a high-class metallic feeling in a bright place, and a nocturnal member in which a part of a pointer or a time letter or a part of a dial is stored in a dark place It is not related to nocturnal decorations that let you know the time by emitting light.

  As described above, the prior art disclosed in Patent Document 1 has a structure in which a large number of through holes are formed in the dial plate and the through holes are filled with the luminous member, so that the time can be set by light emission of the luminous member in a dark place. As you know, in the bright place, it is a technique to secure the metallic feeling by making the through-hole (opening) of the dial inconspicuous, but in the bright place, it has a high-grade metallic feeling with specular gloss. However, in a dark place, it is not possible to recognize the time by displaying with a luminous member that effectively uses external light.

  Accordingly, an object of the present invention is to solve the above-described problems, and is a luminescent ornament that displays using a luminescent member that effectively uses external light, and is a decorative member provided in a display unit. It is intended to provide a nocturnal decoration that can easily obtain and protect a high-quality mirror-like gloss.

  Another object of the present invention is to provide a nocturnal ornament capable of efficiently storing the nocturnal member using external light effectively.

The composition of the luminous ornament in the present invention is as follows.
A nocturnal ornament that has been provided with visibility and decoration in a dark place, a nocturnal member for imparting visibility in the dark, and a decoration member having visibility and decoration in a bright place The luminescent member and the decorative member are mixedly arranged in the same region, the decorative member has an opening that exposes the luminescent member, and has a transparent member on the viewing side of the luminescent member. And

  As a result, the luminous member and the decorative member are mixedly arranged in the same region, and the transparent member is arranged on the decorative member having the opening that exposes the luminous member, so that a predetermined metal film is formed on the transparent member. In this case, a metal film can be formed taking advantage of the surface smoothness of the transparent member. Therefore, it is possible to easily pattern the decorative member having a mirror-like gloss. As a result, the light emission of the nocturnal member can be visually recognized in a dark place, and a decorative member having a specular gloss and a metallic feeling can be obtained in a bright place.

  Moreover, it is good to arrange | position the transparent member on a luminous member and a decoration member.

  Thereby, since a decorative member having an opening can be formed on the transparent member, a decorative member having a mirror surface utilizing the surface smoothness of the transparent member can be obtained, and a smoothing step such as polishing of the surface of the decorative member Can be omitted. Further, since the transparent member can be used as a protective layer for the decorative member, it is difficult to be scratched and the corrosion resistance can be improved.

Moreover, the transparent member is good to arrange | position so that the surface which does not provide the decorative member, and the luminous member may oppose.

  As a result, the decorative member is patterned by utilizing the surface smoothness of the transparent member, and the surface of the transparent member on which the decorative member is not provided is arranged to face the luminous member, so that the decorative member having a specular gloss Can be obtained. The transparent member is disposed between the decorative member and the luminous member and functions as a light guide plate. As a result, external light is taken in through the opening of the decorative member, diffuses in the transparent member and is absorbed by the luminous member, so that the luminous efficiency is improved and the light emission time can be extended.

  Moreover, it is good for a decoration member to have a recessed part for arrange | positioning a luminous member.

  Accordingly, since the luminous member can be formed by directly providing the decorative member with the concave portion, it is possible to form the luminous member on a relatively small part or part thereof, and to provide a luminous ornament that is easy to manufacture. be able to.

  Moreover, the decorative member is a convex part provided on the base material, and a concave part for arranging the luminous member may be formed by the convex part.

  As a result, the decorative member can be patterned in a predetermined area on the rigid base material and the concave portion can be formed, and the luminous member can be arranged in the concave portion formed in the decorative member, so that both rigidity and decorative properties can be achieved. it can. Moreover, the usage-amount of an expensive decoration member can be suppressed.

  Moreover, the shape of the area | region where the luminous member is arrange | positioned is good to differ from the shape of a luminous ornament.

  Thereby, since a luminescent member can be light-emitted in the dark place in the shape different from the shape of a luminescent ornament, a character, a mark, etc. can be light-emitted arbitrarily. Moreover, since it is not necessary to form a luminous member on the whole surface, the usage-amount of a luminous member can be suppressed.

  The transparent member may be a color adjustment layer that adjusts the emission color of the luminous member.

  Thereby, a transparent member can be made into a color adjustment layer by using the transparent member containing dye, a pigment, fluorescent substance, etc. As a result, the color of the luminescent color of the luminous member can be arbitrarily changed.

According to the present invention, a decorative member is formed by taking advantage of the surface smoothness of the transparent member on the luminous decoration provided in the display unit, so that a high-quality specular gloss can be easily obtained and protected. Can provide a luminous decoration.
In addition, since the transparent member acts as a light guide plate, it is possible to provide a nocturnal ornament that can effectively store the nocturnal member by effectively using external light.

[Description of First Embodiment (Four Configuration Examples): FIGS. 1A to 1D]
First, with reference to FIG. 1A to FIG. 1D, a description will be given of the luminescent decoration 50, the luminescent decoration 55, the luminescent decoration 60, and the luminescent decoration 65, which are four configuration examples of the first embodiment. 1A to 1D are cross-sectional views showing main parts of four configuration examples.

  The features of the four configuration examples of the first embodiment are that the luminous member 3 and the decorative member 2 are mixedly arranged in the same region when the luminous ornament is visually recognized, and the luminous member 3 It is the point which has the transparent member 5 in the visual recognition side.

  First, in FIG. 1A, the luminous ornament 50 is arranged so that the decorative member 2 is sandwiched between the luminous member 3 and the transparent member 5, and is joined by a transparent adhesive 5s. The decorative member 2 is made of a decorative metal layer formed on the glossy surface of the transparent member 5 to have a predetermined thickness, for example, gold or platinum by a method such as vacuum deposition or sputtering. For example, the slit-like opening 1 is patterned by a method such as photolithography. The width of the opening 1 of the opening 1 is t, and the width of the decorative member 2 between the openings 1 is w. Specific examples of the width t of the opening 1 and the width w of the decorative member, and the visual recognition and metal feeling will be described later. Although the thickness of the decorative member 2 is exaggerated, the actual thickness is not particularly limited. For example, the metallic feeling and light transmission when visually observed at about 0.1 μm to several μm are used. It is determined appropriately considering the degree.

  Next, in FIG. 1B, the luminescent decoration 55 is arranged so that the decorative member 2 is sandwiched between the luminescent member 3 and the transparent member 5, and is joined by the luminescent adhesive 3s. As the luminous adhesive 3s, a so-called phosphorescent paint in which a known phosphorescent material particle is contained in a transparent adhesive can be used. The thickness and pattern shape of the decorative member 2 are the same as those of the luminous decoration 50.

  Next, in FIG. 1C, the luminous object 60 is such that the decorative member 2 is on the upper surface side of the transparent member 5, and the surface of the transparent member 5 not provided with the decorative member 2 faces the luminous member 3. And are joined by a luminous adhesive 3s or a transparent adhesive 5s. The thickness and pattern shape of the decorative member 2 are the same as those of the luminous decoration 50.

  Next, in FIG. 1D, the nocturnal ornament 65 is coated with the nocturnal adhesive 3 s on the surface of the transparent member 5 on which the decoration member 2 is not provided so that the decoration member 2 is on the upper surface side of the transparent member 5. And solidified. The thickness and pattern shape of the decorative member 2 are the same as those of the luminous decoration 50.

[Description of Light-Emitting Operation: FIGS. 1A to 1D]
In the luminous decorations 50 and 55, the external light incident from the upper surface side of the transparent member 5 is transmitted through the transparent member 5 and has an opening pattern (opening width t, decorative member width w) provided on the decorative member 2. The light enters the luminous member 3 from the opening 1 and is absorbed. And the luminous member 3 which absorbed the light energy of external light will be in an excitation state, and if external light is interrupted | blocked, it will light-emit slowly in the process which returns to a ground state. In this way, the nocturnal decorations 50 and 55 are provided, for example, on the timepieces and hands of a wristwatch, and emit light in a predetermined area at a predetermined position of the display unit. The metallic luster is visually recognized, and the light emission of the luminous member 3 passing through the opening 1 can be visually recognized in a dark place, and the time can be known.

  Next, in the nocturnal decorations 60 and 65, the external light incident from the upper surface side of the decoration member 2 passes through the openings 1 of the opening pattern (opening width t, decoration member width w) provided in the decoration member 2. Then, the light enters the transparent member 5. The light incident on the transparent member 5 is diffused in the transparent member 5 and incident on the luminous member 3 and absorbed. 1A and 1B is different from the luminescent decorations 50 and 55 in that the luminescent member 3 or the luminescent adhesive 3s and the decorative member 2 are arranged via the transparent member 5, so that the external light Is diffused in the transparent member 5, and the entire surface of the luminous member 3 or the luminous adhesive 3s in contact with the transparent member 5 is irradiated with external light. The light emitting operation is basically the same as that of the above-described luminous ornaments 50 and 55, but the luminous property which is in contact with the transparent member 5 also when the luminous member 3 or the luminous adhesive 3s emits light in a dark place. Since the entire surface of the member 3 or the luminous adhesive 3s emits light, the luminous efficiency can be improved and the light emission time can be extended.

[Description of Manufacturing Method: FIGS. 2A to 2F]
Next, a manufacturing method of the four configuration examples of the first embodiment described above will be briefly described. 2A to 2D are cross-sectional views showing the main first half steps S1 to S4 of the method for manufacturing the luminous ornaments 50, 55, 60, and 65, and FIGS. 2E to 2F show the second half manufacturing steps S5-a. , S5-b is a cross-sectional view.

[Description of Manufacturing Steps S1 to S5-b: FIGS. 2A to 2F]
In the manufacturing process S1 shown in FIG. 2A, the transparent member 5 is made of, for example, a transparent resin such as acrylic or polycarbonate, or glass having a specular gloss on the surface. The decorative member 2 is formed to a predetermined thickness on the entire surface of the transparent member 5 by using a method such as sputtering or vapor deposition.

  Next, in the manufacturing process S2 shown in FIG. 2B, a resist 11 is formed in a predetermined pattern on the decorative member 2 formed on the transparent member 5 using a photolithography method or the like.

  Next, in the manufacturing step S3 shown in FIG. 2C, unnecessary portions of the decorative member 2 are removed by an etching method or the like to form a predetermined opening pattern.

  Next, in the manufacturing process S4 shown in FIG. 2D, the resist 11 is removed. Thereby, the decorative member 2 having a predetermined opening pattern is formed on the surface of the transparent member 5. Here, the width of the opening 1 of the opening 1 of the opening pattern provided in the decorative member 2 is t, and the width of the decorative member 2 between the openings 1 is w.

  Then, in the manufacturing process S5-a shown in FIG. 2E, the decorative member 2 of the transparent member 5 is formed by reversing the upper and lower sides of the transparent member 5 on which the decorative member 2 is patterned as shown in FIG. 2D. The surface and the luminous member 3 are adhered to each other using the transparent adhesive 5s or the luminous adhesive 3s. Thereby, the luminous decoration 50 or 55 shown to FIG. 1A and FIG. 1B is formed.

On the other hand, in the manufacturing step S5-b shown in FIG. 2F, the decorative member 2 of the transparent member 5 is formed with the upper and lower sides of the transparent member 5 on which the decorative member 2 is patterned being left in the state shown in FIG. 2D. It adhere | attaches using the transparent adhesive 5s or the luminescent adhesive 3s in the state which made the surface and the luminescent member 3 face each other. Thereby, the luminous decoration 60 shown in FIG. 1C is formed. 1D is formed by disposing only the luminous adhesive 3s on the surface of the transparent member 5 on which the decorative member 2 is patterned, on which the decorative member 2 is not formed.

  In addition, the manufacturing process shown to S1-S4 utilizes the glossiness of the surface of the transparent member 5, and forms the decoration member 2 in a pattern. On the other hand, there is a method of forming the decorative member 2 on the surface of the luminous member 3. In that case, since the surface gloss of the luminous member cannot be expected, it is difficult to obtain a mirror-like gloss. Therefore, it is preferable to select the manufacturing method by examining the necessity of specular gloss depending on the application.

  Further, in the manufacturing process S5-a or S5-b, the transparent adhesive 5s or the luminescent adhesive 3s was used, but in order to avoid adverse effects on the visual recognition such as refraction or interface reflection at the joint surface, the luminescent adhesive For the 3s binder or the transparent adhesive 5s, it is desirable to select a material having a refractive index close to that of the transparent member 5.

[Description of effects]
Since all of the nocturnal decorations 50, 55, 60, and 65 of the four configuration examples of the first embodiment make use of the surface smoothness of the transparent member 5 and form a metal film as the decoration member 2, the bright place Then, it is possible to easily obtain a high-quality mirror-like metallic luster and to provide a nocturnal decoration in which the opening 1 is not conspicuous. Moreover, the luminous member 3 which absorbed external light can perform a predetermined | prescribed light emission display in a dark place.

  In addition, the luminous decorations 50 and 55 are effective in preventing scratches and corrosion resistance because the transparent member 5 functions as a protective layer in the manufacturing process or after commercialization. In addition, since the transparent member 5 acts as a light guide plate and the light that has passed through the opening 1 of the decorative member 2 spreads radially and diffuses, the nocturnal ornaments 60 and 65 are uniformly distributed over the entire nocturnal member 3. Can be irradiated. Therefore, the luminous efficiency of the luminous member 3 can be improved and the light emission time can be extended.

  Since the decorative member 2 is exposed on the outermost surface of the nocturnal ornaments 60 and 65, another transparent member formed to a predetermined thickness is used as the second transparent member 5 as necessary. A protective layer may be provided by adhesion or the like on the surface. On the other hand, the luminous ornaments 50 and 55 may be provided with the second transparent member 5 as a light guide plate between the decorative member 2 and the luminous member 3.

  The luminous ornaments 50, 55, 60, and 65 are basic luminous ornaments in which the transparent member 5 having the decorative member 2 formed on the upper surface of the luminous member 3 is laminated. Taking the display unit as an example, it can be applied to dials, time letters, pointers, logos, parting members, etc., and may be configured as a part of each member or may be configured as a whole.

Although not particularly limited, main metal materials used for the decorative member 2 are listed. For example, gold, silver, platinum and chrome. Further, although not particularly limited, a material used for the transparent member is, for example, a transparent resin such as acrylic or polycarbonate, or glass. Further, although not particularly limited, the material used for the luminous member 3 is, for example, a ZnS-based or SrAl ₂ O _4- based pigment, and the emission color is not particularly limited, but is blue-green, yellow-green, yellow-based. , Orange and the like. Moreover, although not specifically limited, the material of the base material which incorporates the nocturnal decorations 50, 55, 60, 65 is mentioned. For example, metal such as stainless steel, ceramic, resin, glass and the like.

[Explanation of Second Embodiment: FIG. 3A]
Next, the luminous decoration 70 which is 2nd Embodiment is demonstrated using FIG. 3A. FIG. 3A shows a cross-sectional view of the luminous decoration 70.

The feature of the luminous decoration 70 of the second embodiment is that the concave portion 12 for arranging the luminous member 3 is provided in the base material 4, the luminous member 3 is formed in the concave portion 12, and the decoration is provided on the base material 4. This is the point where the member 2 is formed. Since the other basic configuration of the luminous ornament 70 is the same as that of the luminous ornament 50, the same elements are denoted by the same reference numerals, and redundant description is omitted. Only the main points of the manufacturing method will be described.

  In FIG. 3A, for example, a plurality of recesses 12 are formed at predetermined intervals on a base material 4 made of stainless steel or the like, and the luminous member 3 is filled and formed. In addition, the decorative member 2 is formed with a predetermined thickness on the upper surface of the base material 4 and the luminous member 3, and the opening 1 is patterned. The decorative member 2 is formed using the surface of the transparent member 5 in the same manner as the above-mentioned luminous decoration 50. The pitch of the concave portions 12 in which the luminous member 3 is formed is the same as the pitch of the opening portions 1 of the decorative member 2, and the opening portions 1 of the decorative member 2 overlap the luminous member 3. . Moreover, the opening width of the recessed part 12 provided in the decorative member 2 is t, and the width of the decorative member 2 is w, which is the same as that of the above-described luminous decoration 50.

  Next, the manufacturing method of the luminous decoration 70 is demonstrated. First, a recess having a predetermined opening 1 width is formed on the substrate 4 by, for example, etching, and the luminous member 3 is filled and formed in the recess 12 of the substrate 4 with a squeegee or the like and dried and solidified. Next, the transparent member on which the decorative member is patterned is adhered to the upper surfaces of the base member 4 and the luminous member 3 in the same manner as in the above-described step S5-a (see FIG. 2E).

  Thereby, the luminous decoration 70 can be formed by limiting the luminous member 3 to a partial region of the base material, so that the amount of the luminous member 3 used can be reduced and it is economical. In addition, since the width of the recess 12 is wider than the width t of the opening 1 of the decorative member 2, the luminous member 3 can be filled in a relatively large amount. As a result, the light emission time can be extended for a small filling amount of the luminous member 3. The depth of the recess 12 is preferably 200 μm to 300 μm when a general luminescent member 3 is used, but may be appropriately set depending on the light emission time of the luminescent member 3. In addition, the base material 4 can also form a recessed part with the method of deepening by RIE (a kind of dry etching), for example using a silicon substrate.

  As described above, the luminous decoration 70 can obtain a metallic feeling with a specular gloss that the opening 1 of the decorative member 2 is not conspicuous in a bright place, and can perform a predetermined light emitting display in a dark place. It can be a luminous decoration. In addition, although the one recessed part 12 was formed with respect to one opening part of the decoration member 2, it is not limited to it, It is good also as a structure which provides the recessed part 12 ranging over the several opening part of the decoration member 2. FIG.

[Description of Third Embodiment: FIG. 3B]
Next, the luminous decoration 75 which is 3rd Embodiment is demonstrated using FIG. 3B. FIG. 3B shows a cross-sectional view of the luminous decoration 75.

  The feature of the luminous ornament 75 of the third embodiment is that the decorative member 2 is patterned using the concave portion 12 for arranging the luminous member 3 and the luminous member 3 is formed in the concave portion 12. .

  In FIG. 3B, a plurality of recesses 12 are formed on the upper surface of the decorative member 2 at a predetermined interval. The recess 12 provided in the decorative member 2 has the opening width 1 of the opening 1 and the width of the decorative member 2 is w, and is the same as the above-described luminous decoration 50. The recess 12 is filled with the luminous member 3. A transparent member 5 is bonded to the upper surfaces of the decorative member 2 and the luminous member 3.

Next, the manufacturing method of the luminous decoration 75 is demonstrated.
First, the recesses 12 are patterned on the decorative member 2 by etching or the like as the opening width t and the decorative member width w. Next, the luminous member 3 is filled and formed in the recess 12 with a squeegee or the like and dried and solidified. And the transparent member 5 is adhere | attached on the upper surface of the base material 4 and the luminous member 3 using the transparent adhesive 5s.

  As described above, the nocturnal ornament 75 is a nocturnal ornament that can obtain a metallic feeling that the opening pattern of the decoration member 2 is not conspicuous in a bright place and can perform a predetermined light emission display in a dark place. Can do. In addition, since the luminous member 75 can form the luminous member 3 by providing the recess 12 directly on the decorative member 2, the luminous ornament 75 is suitable for a small decorative portion using an expensive decorative member, for example. The depth of the recess 12 is preferably 200 μm to 300 μm when a general luminescent member 3 is used, but may be set in consideration of the light emission time of the luminescent member 3.

[Explanation of Fourth Embodiment: FIG. 3C]
Next, the luminous decoration 80 which is 4th Embodiment is demonstrated using FIG. 3C. FIG. 3C shows a cross-sectional view of the luminous decoration 80.

  The feature of the luminous ornament 80 of the fourth embodiment is that the convex portion by the decorative member 2 is formed on the base material 4 and at the same time, the concave portion 12 for arranging the luminous member 3 is patterned, and the concave portion 12 is luminous. This is the point at which the sexual member 3 is formed.

  In FIG. 3C, decorative members 2 are formed on the upper surface of the base material 4 at a predetermined interval in a convex shape. The recess 12 provided in the decorative member 2 has an opening width t, and the decorative member 2 has a width w, which is the same as the above-described luminous decoration 50. The recess 12 is filled with the luminous member 3. And the transparent member 5 is adhere | attached on the upper surface of the decorative member 2 and the luminous member 3 using the transparent adhesive 5s.

Next, a method for manufacturing the luminous decoration 80 will be described.
First, the decorative member 2 is patterned on the base material 4 with an opening width t and a decorative member width w by electroforming to a predetermined thickness. After removing the resist, the luminous member 3 is filled and formed in the recess 12 and dried and solidified. And the transparent member 5 is adhere | attached on the upper surface of the decoration member 2 and the luminous member 3 using the transparent adhesive 5s.

  As described above, the nocturnal ornament 80 is a nocturnal ornament that can obtain a metallic feeling that the opening pattern of the decorative member 2 is not conspicuous in a bright place and can perform a predetermined light emitting display in a dark place. Can do. In addition, since the nocturnal ornament 80 is a structure which comprises the nocturnal member 3 and the decorating member 2 directly on the upper surface of the base material 4, it can be compatible in both rigidity and decorativeness. For example, the use of the expensive decorative member 2 can be suppressed by forming the luminous decoration 80 in a limited area on the substrate 4, which is economical.

[Explanation of Fifth Embodiment and Three Modifications: FIGS. 4A to 4E]
Next, the luminescent ornament 150 of the fifth embodiment and the luminescent ornament 155, the luminescent ornament 160, and the luminescent ornament 165 of three variations of the cross-sectional configuration will be described with reference to FIGS. 4A to 4E. To do.

  The characteristic of the luminous ornament 150, 155, 160, 165 is that by arranging the luminous member 3 in a shape different from the luminous ornament on the lower surface side of the decorative member 2 having a slit-like opening pattern, In a bright place, a metallic feeling having a specular gloss with an inconspicuous opening pattern of the decorative member 2 can be obtained, and in a dark place, a light emitting display having a shape different from that of the decorative member 2 can be performed. The four luminous objects 150, 155, 160, and 165 have different configurations of the luminous member 3 and the filling member between the decorative member 2 and the luminous member 3, respectively.

In the said 1st Embodiment-4th Embodiment, the luminous property in the dark place by light emission of the luminous member 3 is formed so that the luminous member 3 may be exposed on the side of the luminous ornament. It becomes possible to make it easy to visually recognize the outline of the ornament.

[Explanation of Fifth Embodiment: FIGS. 4A and 4B]
First, the luminous decoration 150 will be described with reference to FIGS. 4A and 4B.
4A shows a plan view of the luminous decoration 150, and FIG. 4B shows a cross-sectional view taken along the cutting line FF ′ shown in FIG. 4A. 4A, the decorative member 2 constituting the luminous ornament 150 has a plurality of slit-like openings 1 formed at substantially equal intervals and patterned (the opening pattern of the decorative member 2 is the same as that of the transparent member 5). Because it is the bottom side, it is indicated by a broken line). Each opening 1 is set to an opening width t and a width w of the decorative member.

  Next, in FIG. 4B, the transparent member 5 is disposed on the uppermost surface, and the decorative member 2 is formed on the lower surface side of the transparent member 5. On the lower surface side of the decorative member 2, a luminous member 3 is formed in a predetermined thickness, for example, in the shape of the numeral “4” in plan view. A base material 4 is disposed on the lower surface side of the luminous member 3. Further, the space around the luminous member 3 sandwiched between the decorative member 2 and the base material 4 is filled with a filling member 6 having the same color as the luminous member 3. The luminous member 3 and the filling member 6 are bonded to the base material 4 using a transparent adhesive 5s.

Next, a method for manufacturing the luminous decoration 150 will be described.
As shown in the manufacturing step S4 (see FIG. 2D) described above, the luminous member 3 is used as the decorative member 2 in the state where the decorative member 2 formed on the transparent member 5 is on the upper surface side. To form. Although not particularly limited, for example, a method such as silk printing may be used. After the luminous member 3 is formed and solidified, the filling member 6 is applied (or filled) around the surface and flattened. Then, the decorative member 2 side is made to oppose the base material 4, and it joins to the base material 4 using the transparent adhesive material 5s. Here, the filling member 6 uses, for example, a paint or resin containing a pigment having the same color as that of the luminescent member 3, so that the luminescent member 3 can be visually recognized from above the opening pattern of the decorative member 2. It can be made inconspicuous. If the color of the luminous member 3 visually recognized from the upper side of the opening pattern of the decorative member 2 is not so noticeable, the filling member 6 may not be used.

[Description of flash operation]
The luminous member 3 is formed, for example, in the area of the number “4” on the lower surface side of the slit-shaped opening pattern formed in the decorative member 2. In a bright place, external light passes through the slit-shaped opening from the upper surface of the transparent member 5, accumulates in the luminous member 3, and emits light in the dark place. And as shown to FIG. 4A, the light emission part 9 (hatching part) light-emits in slit shape. Actually, the width and pitch of the slit cannot be visually recognized, but can be visually recognized as “4” by human eyes (the figure is exaggerated for the sake of explanation). On the other hand, in a bright place, the slit-shaped opening pattern formed in the decorative member 2 can provide a metallic feeling having a specular gloss that the opening 1 of the decorative member 2 is not conspicuous.

  Thereby, the luminous ornament 150 can emit light in a shape (for example, numeral 4) different from the outer shape of the luminous ornament 150 in a dark place, and a mirror-like gloss with an inconspicuous opening pattern in a bright place. The outer shape of the nocturnal ornament 150 having a metallic feeling having a rectangular shape can be made into a square. In the bright place, the surrounding of the luminous member 3 is filled with the filling member 6 having the same color as the luminous member, so that the white-green color characteristic of the luminous member can be made inconspicuous. Moreover, although the luminous member was formed as the number “4”, the present invention is not limited to this, and other numbers, characters, marks, and logos may be formed.

[Description of Luminous Decoration 155 (First Modification of Fifth Embodiment): FIG. 4C]
Next, the luminous ornament 155 (first modification in the fifth embodiment) will be described with reference to FIG. 4C. FIG. 4C shows a cross-sectional view of the luminous ornament 155 of the first modified example along the same cutting line as FIG. 4A. The place where the luminescent decoration 155 differs from the structure of the luminescent member 150 is that the lower surface side of the luminescent member 3 and the surrounding space are filled with the filling member 6 of the same color as the luminescent member. Since the other basic configuration is the same as the configuration of the luminous decoration 150, the same elements are denoted by the same numbers or the same reference numerals, and redundant description is omitted.

  By setting it as such a structure, the process of planarizing the luminous member 3 and the filling member 6 becomes unnecessary, and manufacture is easy. Moreover, it is easy to change the thickness of the luminous member 3. The luminous operation and effect of the luminous ornament 155 are the same as those of the luminous ornament 150.

[Description of Luminous Decoration 160 (Second Modification of Fifth Embodiment): FIG. 4D]
Next, the luminous decoration 160 (the 2nd modification in 5th Embodiment) is demonstrated using FIG. 4D. FIG. 4D shows a cross-sectional view of the luminous ornament 160 of the second modified example along the same cutting line as FIG. 4A. The place where the luminescent decoration 160 differs from the structure of the luminescent member 150 is that the transparent member 5 and the decorative member 2 and the filling member 6 provided on the base material 4 are bonded together by a transparent adhesive 5s. In the lower surface side of the luminous member 3, a layer of the filling member 6 having the same color as the luminous member 3 is formed between the luminous member 3 and the base material 4. Since the basic configuration is the same as the configuration of the luminous ornament 150, the same elements are denoted by the same numbers or the same reference numerals, and redundant description is omitted.

  By setting it as such a structure, the layer of the luminous member 2 and the filling member 6 can be easily adhere | attached using the transparent adhesive 5S. The formation of the layer of the filling member 6 is not particularly limited, but may be a method of applying a resin or a method of bonding in the form of a film. The luminous operation and effect of the luminous ornament 160 are the same as those of the luminous ornament 150.

[Description of Luminous Decoration 165 (Third Modification of Fifth Embodiment): FIG. 4E]
Next, the luminous decoration 165 (third modified example in the fifth embodiment) will be described with reference to FIG. 4E. FIG. 4E shows a cross-sectional view of the luminous ornament 165 of the third modification along the same cutting line as FIG. 4A. The place where the luminous ornament 165 is different from the configuration of the luminous member 150 is that the decorative member 2 is formed on the upper surface side of the transparent member 5 and the layer of the filling member 6 is formed on the lower surface side of the transparent member 5. is there. Although the decorative member 2 and the transparent member 5 are upside down with respect to the configuration of the luminous ornament 150, the other components are the same. Is omitted.

  By setting it as such a structure, the shape of the luminous member 3 can be formed easily and correctly. The space around the portion where the luminous member 3 protrudes from the hollow portion of the filling member 6 may be filled and bonded with the transparent adhesive 5s, or the luminous adhesive 3s may be bonded to the hollow portion of the filling member 6. In addition, the luminous adhesive 3s may serve as an adhesive layer with the substrate 4 without using the transparent adhesive 5s. The filling member 6 is not particularly limited. For example, a metal film may be formed on the surface of the transparent member 7 by a sputtering method or the like, or a paint or a resin containing a pigment or the like may be formed by silk printing or the like. Good. Preferably, the color of the luminescent member is made inconspicuous as the same color as the luminescent member 3. Further, as described in the luminous ornaments 60 and 65 of the first embodiment, the second transparent member 5 may be provided as a protective layer of the decorative member 2. The luminous operation and effect of the luminous ornament 165 are the same as those of the luminous ornament 150.

[Description of transparent member having color adjustment function]
In the luminous ornaments in the embodiments, configuration examples, and modifications described so far, the transparent member 5 used to obtain a specular gloss on the decorative member 2 is on the viewing side of the luminous member 3. Since it is provided, by coloring the transparent member 5, it is possible to change the color of the specific emission color emitted from the luminous member 3. For example, by using a transparent resin such as acrylic, polycarbonate, or other transparent resin, or glass containing dyes, pigments, phosphors, or composites thereof, the luminous property of emitting light in the dark The color of light emitted from the member 3 can be changed.

For example, when a phosphor (Ca _1.2 Eu _0.8 SiO ₄ ) is used, a color adjustment layer having an excitation band in the wavelength range of 350 nm to 500 nm and an emission peak at 650 nm (orange red) is obtained. it can. Further, although not particularly limited, other phosphors, dyes, and pigments may be used. Alternatively, a dielectric film or the like may be formed on the surface of the transparent member 5 to change the color of the emitted color using light interference.

  Thus, in each embodiment, the transparent member 5 can be used as a color adjustment layer. In the description of the luminous ornaments 60 and 65 according to the first embodiment and the luminous ornament 165 according to the fifth embodiment, an example in which the second transparent member 5 is provided to serve as a protective layer of the decorative member 2. However, the color adjustment layer can be applied to the second transparent member 5 as well.

[Description of Pattern of Opening and Metallic Feeling According to Each Embodiment: FIGS. 5A to 7B]
Next, the relationship between the visual recognition of the opening pattern of the decorative member according to each embodiment and the metal feeling will be described with reference to FIGS. 5A to 7B.

  Here, although it demonstrates in detail using the opening pattern of the nocturnal decoration 50 demonstrated in FIG. 1A of 1st Embodiment, three opening which changed the width | variety t of the opening part 1 and the width | variety w of the decoration member was changed. Examples of patterns (first to third opening patterns) are illustrated and described as a luminous ornament 50a, a luminous ornament 50b, and a luminous ornament 50c, respectively.

[First Opening Pattern Example: FIGS. 5A and 5B]
FIG. 5A shows a plan view of the luminous ornament 50a, and FIG. 5B shows a cross-sectional view taken along a cutting line AA ′ in FIG. 5A. In FIG. 5A, the slit-shaped openings 1 formed in the decorative member 2 are aligned at substantially equal intervals, the width of the openings 1 is t, and the distance between the openings is w. 5B shows an example in which the decorative member 2 is formed on the upper surface of the luminous member 3, and the transparent member 5 is indicated by a one-dot chain line.

  The luminous decoration 50a is illustrated assuming that the width t of the opening 1 is about 3 μm and the width w of the decoration member 2 is about 15.5 μm.

[Second Opening Pattern Example: FIGS. 6A and 6B]
6A shows a plan view of the luminous ornament 50b, and FIG. 6B shows a cross-sectional view taken along the cutting line BB ′ of FIG. 6A. The luminous decoration 50b is illustrated assuming that the width t of the opening 1 is about 15.5 μm and the width w of the decorative member 2 is about 3 μm.

[Third opening pattern example: FIGS. 7A and 7B]
FIG. 7A shows a plan view of the luminous ornament 50c, and FIG. 7B shows a cross-sectional view taken along the section line CC ′ of FIG. 7A. The luminous decoration 50c is illustrated assuming that the width t of the opening 1 is about 3 μm and the width w of the decorative member 2 is about 3 μm.

  Here, in a bright place, the smaller the width t of the opening 1 is, the more difficult it is to visually recognize the pattern, and the larger the width t, the easier it is to visually recognize the pattern. Further, in a dark place, the smaller the opening width t of the opening 1 is, the more difficult it is to visually recognize the emission of the luminous member 3, and the larger the opening width t, the easier it is to visually recognize the emission. Detailed description regarding the visual recognition of the opening pattern in such a bright place and the visual recognition of the emission of the luminous member 3 in the dark place will be described later.

On the other hand, in the bright place, the smaller the width w of the decorative member 2 is, the thinner the metal feeling is, and the larger the width w is, the more the metal feeling is increased. It was confirmed that the feeling of metal increased as the occupied area of 2 increased. Based on this, the area of the decorative member 2 in the three opening pattern examples is compared, and the luminous decoration 50a> the luminous decoration 5
0c> Luminous decoration 50b.

  That is, it can be seen that the metallic feeling of the luminous decoration 50a is the largest, and then the metallic feeling is smaller in the order of the luminous decoration 50c and the luminous decoration 50b. Therefore, it is important for the metal feeling of the decorative member 2 to consider the area ratio of the decorative member 2 in addition to the width w of the decorative member 2.

[Explanation of relationship between opening width t, viewing distance L, and visual acuity: FIGS. 8, 9A, and 9B]
Next, the relationship between the width t of the opening 1 and the visual recognition will be described.

  FIG. 8 is a graph showing the relationship between the width t of the opening 1, the viewing distance L (m), and the human eyesight when a human visually recognizes the opening 1 of the decorative member 2. FIG. 9A is a table showing the relationship between age (years), diopters (D), and near points (cm), and FIG. 9B is a graph showing the relationship between age and near points. . The diopter (D) is a reciprocal of the focal length of the human eye expressed in meters.

[Explanation of visual acuity: FIG. 8]
In FIG. 8, the horizontal axis of the graph indicates the visual recognition distance L (m) between the visual recognition object and the human eye, and the vertical axis indicates the width t (μm) of the opening 1 of the decorative member 2. Reference sign S1 indicates the visual recognition characteristic when the human eyesight is 1.5. Reference sign S1 is represented by a straight line related to the viewing distance L and the width t of the visible opening 1 and is indicated by a thick solid line in the figure.

  The region above the solid line S1 is a region where the width t of the opening 1 can be visually recognized. The region below the solid line S1 is a region where the width t of the opening 1 cannot be visually recognized.

  The solid line S <b> 1 indicates that the width t of the opening 1 can be visually recognized better as the viewing distance L is smaller, and the width t of the opening 1 is less visible as the viewing distance L is larger.

  For reference, reference sign S2 indicates the visual characteristics when the visual acuity is 2.0, and is indicated by a broken line in the drawing. The broken line S2 is a straight line that indicates that the width t of the opening 1 is better visible as the viewing distance L is smaller as in the case of the solid line S1, and the width t of the opening 1 is less visible as the viewing distance L is larger. S2 is below the graph than the solid line S1, and indicates that the ability to visually recognize the width t of the opening 1 is high because the upper region of the straight line is wider than the solid line S1.

  Here, the visual acuity is generally defined by the following mathematical formula 1. L indicates the distance (m) from the human eye to the target, and t indicates the minimum size (mm) that can be visually recognized.

また、数式１についてｔを求める式に変形すると以下の数式２となる。

Further, when Equation 1 is transformed into an equation for obtaining t, Equation 2 below is obtained.

数式２において、ｔは、Ｌに比例することを表しているので、視力Ｓ１及び視力Ｓ２は、図８に示す様な直線となることを示している。

In Formula 2, since t represents that it is proportional to L, it has shown that visual acuity S1 and visual acuity S2 become a straight line as shown in FIG.

Here, in general, in human visual acuity, visual acuity 1.5 is considered to be well visible, and it is considered that there are considerably few humans with visual acuity 2.0 that are considered to have good visual acuity. Therefore, in the following description, human vision with a visual acuity of 1.5 is considered as a reference.

[Explanation of age, diopters and near points: Fig. 9A, Fig. 9B]
The human eye can adjust the focus, and a unit called diopter (D) is used as a unit for expressing the adjusting power. Diopter is the reciprocal of the focal length of the human eye in meters. The diopter indicates that the focus adjustment can be performed at a close distance when the value is large, and the distance at which the focus adjustment can be performed increases as the value decreases. The diopter is defined by the following well-known formula 3. D indicates the diopter value, and the near point indicates the closest distance at which the human eye can focus.

また、数式３について近点を求める式に変形すると以下の数式４になる。

Further, when Equation 3 is transformed into an equation for obtaining a near point, Equation 4 below is obtained.

図９Ａに示す表において、ディオプトリ（Ｄ）は年齢とともに変化することを示している。また、数式４を用いて近点（ｃｍ）を計算することができる。これにより、年齢と、ディオプトリ（Ｄ）、近点（ｃｍ）の相関がわかり、年齢が増すにつれて近点が遠くなることがわかる。図９Ｂは、この近点（ｃｍ）と年齢の相関をグラフに現したものである。

In the table shown in FIG. 9A, diopter (D) indicates that it changes with age. Further, the near point (cm) can be calculated using Equation 4. As a result, the correlation between age, diopter (D), and near point (cm) is known, and it can be seen that the near point becomes farther as the age increases. FIG. 9B is a graph showing the correlation between this near point (cm) and age.

  According to the graph shown in FIG. 9B, the near point is the shortest 8 cm with a peak at about 10 to 15 years of age, and 100 cm at the age of 60. That is, the peak value of the near point is about 8 cm, which indicates that humans around 10 to 15 years old have the highest focus adjustment power.

  Here, the peak value of a human near point seen around 10 to 15 years old is shown in the graph of FIG. 8 as Lm1 (dashed line). Lm1 is shown at a position parallel to the vertical axis and 0.08 m on the horizontal axis. The area on the right side of Lm1 is an area that can be focused, and the area on the left side of Lm1 is an area that cannot be focused even by a human of an age (around 10 to 15 years old) who has the most ability to adjust focus. . The left region of this Lm1 is referred to as Ar1.

[Explanation regarding visual recognition of light emission of luminous member: FIG. 8]
Next, the visual recognition of the light emission of the luminous member 3 below the decorative member 2 in a dark place will be described. In a dark place, the light emission of the luminous member 3 depends on the width of the opening 1 formed in the decorative member 2, and there is a limit that the light cannot be visually recognized as the width of the opening 1 becomes narrower.

  The inventors changed the value of the width t of the opening 1 formed in the decorative member 2 and the type of the opening pattern and performed a prototype experiment. As a result of repeated experiments in a dark place, it was found that it is difficult to visually recognize the light emission of the luminous member when the width t of the opening 1 is less than 3 μm.

  The lower limit value of the width t of the opening 1 where the light emission of the luminous member 3 can be visually recognized is shown in the graph of FIG. 8 as Lm2 (dashed line). Lm2 is parallel to the horizontal axis and indicated at a position of 3 μm on the vertical axis. The region above Lm2 is a region where light emission of the luminous member 3 can be visually recognized in a dark place, and the region below Lm2 is a region where light emission is difficult to visually recognize. The lower region of Lm2 is referred to as Ar2.

[Explanation of the width t of the opening visible in the light: FIG. 8]
In FIG. 8, as described above, the region above the straight line S1 is a region where the width t of the opening 1 can be visually recognized. The area on the right side of Lm1 is an area where focus adjustment is possible.

  Here, the coordinates of the intersection between the straight line S1 and the focus adjustment limit line Lm1 are obtained. When the intersection is calculated using Expression 2, when L = 0.08 m, the width t of the opening 1 is about 15.5 μm. Here, the limit line indicating t = 15.5 μm is shown in the graph of FIG. 8 as Lm3 (dashed line).

  In FIG. 8, if the upper region of the solid line S1 and the region on the right side of Lm1 (the hatching region above the intersection of the visual acuity S1 and Lm1) is Ar3, Ar3 is in focus and the width t of the opening 1 Is 15.5 μm, and the opening 1 can be visually recognized.

  On the other hand, the region above the solid line S1 and the region below Lm3 is a region where the width t of the opening 1 can be visually recognized in calculation, but exceeds the limit of the focus adjustment capability. Since it cannot be visually recognized as a clear image, it cannot be visually recognized as a result. In addition, as described above, the region below the solid line S1 is a region where the width t of the opening 1 cannot be visually recognized even if focus is achieved.

[Explanation of the width t of the opening that can be seen in the dark, but not visible in the light: FIG. 8]
As described above, the width of the opening 1 where the light emission of the luminous member 3 can be visually recognized in a dark place is 3 μm or more, and the width t of the opening 1 which cannot be seen in a bright place is less than 15.5 μm. That is, in the graph shown in FIG. 8, in the region between the vertical axes Lm2 and Lm3, the light emission of the luminous member 3 can be visually recognized in the dark place, and the opening 1 of the decorative member 2 cannot be visually recognized in the bright place.

  In this way, by setting the width t of the opening 1 of the opening pattern formed in the decorative member 2 to 3 μm or more and less than 15.5 μm, a human with a visual acuity of 1.5 can emit light from the nocturnal member 3 in the dark. Can be seen, and it can be set as the nocturnal decoration which cannot see the width | variety t of the opening part 1 of the decoration member 2 in a bright place.

  Here, as described above, the relationship between the pattern of the opening 1 (the width t of the opening 1 and the width w of the decorative member 2) and the metal feeling (see FIGS. 5A to 7B) needs to be considered. The width t of the opening 1 that can visually recognize light emission and cannot be visually recognized in a bright place is set to 3 μm or more and less than 15.5 μm as a guideline, and at the same time, the metal feel takes into account the width w and area ratio of the decorative member It is necessary to confirm by trial manufacture.

In addition, the human eyesight characteristic with a visual acuity of 1.5 has been described as a reference. For example, a human with a visual acuity of 2.0 makes the width of the opening 1 slightly easier to see. For example, when the visual acuity 2.0 is calculated using Formula 2, the width t of the opening 1 that cannot be visually recognized is about 11.6 μm (see Lm3 in FIG. 8). Therefore, depending on the product, the width t of the opening 1 may be adjusted in consideration of this.
[Description of Variation of Opening Pattern: FIG. 10]
FIG. 10 shows modified examples (1a to 1d) of the opening pattern provided in the decorative member 2. In addition to the slit-like pattern shown in each of the above-described embodiments or configuration examples, 1a is a lattice-like pattern, 1b is a honeycomb-like pattern, 1c is a pattern in which square holes are arranged in a lattice-like shape, and 1d is a round hole. It is a pattern arranged in a grid pattern.

The opening pattern shown in FIG. 10 is formed with a width t of the opening 1 of 3 μm or more and less than 15.5 μm, but the detailed shape of the pattern and the width and area ratio of the opening 1 are prototyped for visibility. It is desirable to confirm and determine the metal feeling. In this way, the width and pattern of the opening 1 are determined and formed, whereby the light emission of the luminous member 3 can be visually recognized in a dark place, and the opening 1 cannot be visually recognized (or is not conspicuous) in a bright place. It can be set as the nocturnal decoration which has.

  The opening pattern is not limited to the above-described pattern, and may be another pattern having the same purpose. Further, the present invention can be applied to all the embodiments, configuration examples, and modifications already described.

[Explanation of Application Examples Using Luminous Decoration for Pointer-type Wristwatch: FIGS. 11A to 11C]
Next, an application example in which a luminous ornament is used for a pointer type wristwatch will be described with reference to FIGS. 11A to 11C. FIG. 11A is a cross-sectional view of a wrist watch 500 to which a luminous ornament is applied, FIG. 11B is a plan view of the information display unit 120, and FIG. 11C is a perspective view of a B portion shown in FIG. 11B.

  A feature of the wristwatch 500 is that a configuration example of a luminous ornament is applied to the configuration using the luminous pointer 107 and the luminous time character 105a in the information display unit 120.

  First, in FIG. 11A, the wristwatch 500 has the information display unit 120 and the movement 109 mounted inside the outer case 101, and press-fits the windshield member 102 together with the packing 103 from one side of the outer case 101 (above FIG. 11A). The back cover 111 is fitted from the other side (the lower side of FIG. 11A).

  Next, the information display unit 120 includes a dial 106 on which a luminous time character 105a to which the luminous decoration of the present invention is applied is arranged, a luminous indicator 107, a parting member 108, and the like, and can display the time. Yes.

  The movement 109 includes an electronic circuit and a mechanical drive mechanism that drives the luminous pointer 107 and a battery.

  After the information display unit 120 and the movement 109 are mounted on the exterior case 101, the back cover 111 is fitted and fixed by press-fitting or the like from the back side of the exterior case (downward in FIG. 11A) via the back cover spacer 110.

  Next, in FIG. 11B, the luminous hour letters 105a are arranged on the outer peripheral portion of the dial plate 106 at predetermined angular intervals in the circumferential direction inside the parting member 108. The 12 o'clock time character can be distinguished from other time characters. The luminous hour hand 107b, the luminous minute hand 107a, and the luminous hour character 105a are in a positional relationship such that the luminous portions do not overlap with each other in the radial direction in a plan view, thereby facilitating reading of the time in a dark place.

  Here, in the luminous pointer 107, a luminous ornament is formed on the luminous hour hand 107b and the luminous minute hand 107a. For example, it is incorporated in a base material (for example, stainless steel) that forms a pointer with the same configuration as that of the above-mentioned luminous decoration 50 (see FIG. 1A). In addition, a plurality of slit-like openings 1 are formed and patterned in predetermined areas of the night hour hand 107b and the night minute hand 107a, respectively. Here, the illustration of the transparent member 5 is omitted.

  Moreover, the luminous time character 105a has the same configuration as that of the luminous decoration 50, for example. The luminous hour letter 105a is formed by patterning a plurality of slit-like openings 1 formed in the decorative member 2 by covering the periphery of the rectangular luminous member 3 with the decorative member 2. Similarly, the transparent member 5 is not shown.

Next, in FIG. 11C, the width t of the slit-shaped opening 1 provided in the luminous minute hand 107a and the luminous hour character 105a is in the range of t = 3 μm or more and less than 15.5 μm. The width w of the decorative member is determined in consideration of the metal feeling. For ease of explanation, the width t of the opening 1 and the width w of the decorative member 2 are exaggerated to be larger than actual.

  As described above, the luminous indicator 107 (107a, 107b) and the luminous hour character 105a have a mirror-like glossy metallic feeling by using the glossy surface of the transparent member for the decorative member 2, and the opening pattern is an opening. The width t of the portion 1 is formed in the range of 3 μm or more and less than 15.5 μm, and the width w of the decorative member 2 determines the area ratio in consideration of the metallic feeling.

  Thereby, the wristwatch 500 can visually recognize the light emission of the luminous member 3 in a dark place and can know the time. Further, in a bright place, the opening pattern of the decorative member 2 cannot be visually recognized (or is inconspicuous) and has a specular gloss, and can be a wristwatch with a metallic feeling. Further, for example, by incorporating the luminous ornament 150, it is possible to perform display in which light is emitted in a shape different from that of the luminous ornament in a dark place. Moreover, it can also be set as the wristwatch which makes the transparent member 5 contain dye, a pigment, etc., and performs the display etc. which change the color of luminescent color.

  In addition, in the other structural member of the information display part 120 which comprises the wristwatch 500, all the structure and opening pattern of all the luminous decorations mentioned above are applicable. Although not particularly limited, for example, there are a second hand, a logo, a parting member, a calendar, an exterior case, and the like.

  As described above, various embodiments and configuration examples and application examples of the luminous ornament have been described in detail. However, the present invention is not limited to such embodiments, configuration examples, and application examples, and detailed configurations. The material, quantity, etc., can be arbitrarily changed, added, or deleted without departing from the spirit of the present invention. That is, the present invention is not limited to the above-described embodiments, configuration examples, and application examples of the nocturnal ornament, and it is not necessary to perform all of them, and various modifications can be made within the scope of the contents described in the claims. Can be changed or omitted.

  INDUSTRIAL APPLICABILITY The present invention can be applied to an application for correctly reading information even in a dark place at night using a luminous member having a luminous property, such as a watch, an electronic device, a display board, and the like. It is particularly suitable for decorative products that find value in beauty and products that require visibility to read information correctly and excellent decorative properties.
