Description

  The present invention relates to a luminous ornament applied to a wristwatch, a portable electronic device, various instruments, and the like, and imparts visibility and decoration in a bright place during the day and visibility and decoration in a dark place at night. Related to luminescent decorations.

  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 printing or sticking it in the form of a sheet, and in a bright place in the daytime (hereinafter referred to as “light place”), energy is stored in the phosphorescent part by external light. In a dark place at night, a phosphorescent part is made to emit light so that the time can be visually recognized.

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

  In response to such a demand, conventionally, for example, a pointer-type wristwatch is taken as an example, and the structure of the member constituting the dial and the luminous member is devised so that the luminous member is not conspicuous in a bright place. The time display scale printed on the dial is visually recognized to know the time, and in the dark, the time display scale is illuminated as a black shadow by using the light emitted from the luminous material stored in the light as a backlight. Proposals have been made to know the time by visual recognition. (For example, refer to Patent Document 1).

  The prior art shown in Patent Document 1 is composed of a metallic lower surface plate and an upper surface member disposed thereabove as a structure of a dial plate, and a metal oxide based on ceramics on the entire upper surface or a part of the lower surface plate. A structure in which a luminous member made of a material is applied, a clear lacquer is further applied to the surface of the luminous member, and the upper surface of the clear lacquer is polished and planarized so that the upper surface member is adhered and fixed with an adhesive or the like It has become. The top member is made of a very thin transparent material such as a mineral such as sapphire glass or quartz, or a synthetic resin. By making the watch dial like this, it is possible to know the time by visually checking the time display scale formed by printing or bonding a metal wire on the upper surface member in the light place, and in the light place in the dark place. Illumination (backlight) from behind the upper surface member by the stored luminous member allows the time display scale to be visually recognized as a black shadow to know the time. As a result, different dials can be displayed in light and dark places.

Japanese Unexamined Patent Publication No. 7-43477 (first page, FIG. 2)

However, the prior art disclosed in Patent Document 1 knows the time because the time display scale is visually recognized as a black shadow by illuminating with a luminous member from behind the upper surface member on which the time display scale is printed. However, since there is no difference between the shape of the time display scale in the bright place and the shape of the time display scale in the dark place, and it is visually recognized as a black shadow, there is a problem that it is difficult to obtain an attractive decoration. There is also a proposal to obtain a decorative effect such that a nocturnal member divided in a lattice shape is arranged on the upper surface of the bottom plate, and the moonlight passing through a shoji of the full moon is seen through the translucent ground glass-like upper surface member. However, the white-green color peculiar to the luminous member can be seen through the translucent ground glass-like upper surface member. Although proposals have been made to embed ultra-thin Japanese paper or fabric in the upper surface member to maintain the decorativeness, there is a new problem that the brightness of transmitted light is impaired.

  As described above, the prior art disclosed in Patent Document 1 is a method in which the light emitted from the luminous member is used as a backlight from behind the upper surface member, so that it is difficult to obtain a decorative appearance that is different from the bright place in a dark place. . On the other hand, there are restrictions on the decorativeness because a metal member (for example, an indicator or the like) that blocks illumination from behind cannot be used frequently. Moreover, the white-green color characteristic peculiar to a luminescent member can be seen through the upper surface member, and the problem of lack of decorativeness cannot be solved.

  Accordingly, an object of the present invention is to solve the above-described problems, and is a luminescent ornament that effectively uses external light, and in a dark place, a gradation pattern, characters, and patterns are emitted by light emission of the luminescent member. It is to provide a nocturnal decoration that has been given a gorgeous visibility and decoration.

  Another object of the present invention is to provide visibility and decorativeness capable of drawing letters and designs having a desired metallic feeling and desired color in a bright place, and to provide a white-green color peculiar to a luminous member. The object is to provide a nocturnal decoration that makes the color of the system inconspicuous.

The composition of the luminous ornament in the present invention is as follows.
A luminous ornament that has been provided with visibility and decoration in a dark place, a luminous member for imparting visibility in the dark, and a decoration member having visibility and decoration in a bright place, The nocturnal member and the decorative member are arranged in the same region, and the same region has regions having different light transmittances.

  As a result, the luminous object can be arranged in the same region with the luminous member and the decorative member arranged in the same area so that it can have the function as the luminous member and the function as the decorative member at the same time. A region having different light transmittance can be formed in the region to create a light / dark difference in light emission. Moreover, it can have a metallic feeling in a bright place. As a result, in the dark place, it is possible to provide a nocturnal ornament that is provided with a graceful visibility and decorativeness by drawing a gradation pattern, characters and the like due to the difference in brightness of the luminous member. Further, in a bright place, it is possible to impart visibility and decorativeness with a metallic feeling and make the white-green color characteristic of the nocturnal member inconspicuous.

  In addition, the regions having different light transmittances are preferably strip-shaped or dot-shaped regions.

  Thereby, a band-like or dot-like region can be formed in the same region, and the light transmittance of each region can be changed. As a result, in a dark place, it is possible to draw a gradation pattern, a character, a picture, or the like due to the difference in brightness of light emission. In a bright place, characters or shapes having a metallic feeling can be formed.

  Further, the decorative member may have regions having different thicknesses.

Thereby, the transmittance | permeability of light can be changed by forming the area | region where thickness differs in a decoration member. As a result, in the dark place, it is possible to draw more various gradation patterns, characters, pictures, and the like due to the difference in brightness of light emission. In a bright place, characters or shapes having a metallic feeling can be formed.

  The decorative member may be a colored layer containing colored particles in a metal film or resin.

  Thereby, the decoration member can form a colored layer containing colored particles in a metal film or resin in a desired region. As a result, in a dark place, it is possible to draw a gradation pattern, a character, a picture, or the like due to a difference in brightness of light emission by changing the light transmittance. Further, by using predetermined colored particles in the colored layer, it is possible to draw a gradation pattern, a character, a pattern, or the like having a desired color. In a bright place, it is possible to draw characters and designs having a desired metallic feeling or a desired color.

  In addition, the colored layer may have a region where the content of the colored particles is different.

  Thereby, in the colored layer of the desired region of the decorative member, the light transmittance can be variously changed by changing the content (density) of the colored particles contained in the resin. As a result, it is possible to draw gradation patterns, characters, designs, and the like using various light emission contrasts in a dark place. In the bright place, letters and designs with various colors can be drawn.

  In addition, the decorative member may have a plurality of openings that expose the luminous member, and may have regions having different ratios of the luminous member and the decorative member in the same region.

  Thereby, the decorative member has a plurality of band-shaped or dot-shaped openings that expose the luminous member, and the luminous component is arranged so that the luminous member and the decorative member are mixed in the same region. And, it can have a function as a decorative member and a function as a luminous member at the same time. In addition, since the ratio where the luminous member and the decorative member are mixed can be different in the same region, the light transmittance can be changed in a dark place to create a light-dark difference. In a bright place, it can have a metallic feeling. As a result, it is possible to provide a nocturnal ornament that has a gradual visibility and decoration by drawing gradation patterns, characters, patterns, and the like due to the difference in brightness of light emission in a dark place. Visibility and decorativeness having a metallic feeling can be imparted, and the white-greenish color characteristic of the luminous member can be made inconspicuous.

  In addition, the plurality of openings may be different from each other in the width of adjacent openings in the same region.

  Thus, the luminous decoration can change the ratio of the luminous member and the decorative member mixed in the same region by changing the widths of the adjacent openings of the decorative member. As a result, in a dark place, the light transmittance can be changed to form a bright region and a dark region of light emission, so that a gradation pattern, a character, a pattern, etc. can be drawn due to a difference in brightness. Further, in a bright place, it is possible to impart visibility and decorativeness having a desired metallic feeling and to make the white-green color characteristic of the nocturnal member inconspicuous.

  The plurality of openings may have different arrangement densities of the plurality of openings in the same region.

  Thereby, the luminous decoration can change the ratio in which the luminous member and the decorative member coexist in the same region by changing the arrangement density of the openings of the decorative member. As a result, in a dark place, the light transmittance can be changed to form a bright region and a dark region of light emission, so that a gradation pattern, a character, a pattern, or the like can be drawn due to a light / dark difference. Further, in a bright place, it is possible to impart visibility and decorativeness having a desired metallic feeling and to make the white-green color characteristic of the nocturnal member inconspicuous.

  In addition, at least one of the plurality of openings may have a portion where the widths of the openings are different.

  As a result, the luminous ornament has a portion where the width of at least one opening is different, thereby changing the light transmittance in a dark place to form a bright region and a dark region of light emission, thereby reducing the difference in brightness. Can be made. As a result, it is possible to draw a gradation pattern, a character, a pattern, or the like due to a light / dark difference in a dark place. Further, in a bright place, it is possible to impart visibility and decorativeness having a desired metallic feeling and to make the white-green color characteristic of the nocturnal member inconspicuous.

  According to the present invention, it is a nocturnal ornament that effectively uses external light, and the nocturnal member and the ornamental member are arranged in the same area, and have areas with different light transmittances in the same area. In a dark place, a bright region and a dark region of the luminous member can be formed. Thereby, since a gradation pattern, a character, a pattern, etc. by the brightness difference of light emission and a color can be drawn, the nocturnal ornament which provided quaint visibility and decoration nature can be provided. In addition, in the bright place, visibility and decoration that can draw letters, shapes, patterns, etc. with the desired metallic feeling and desired color are given, and the white-green color characteristic of the luminous member is conspicuous Lost luminescent decoration can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiment described below exemplifies a luminous ornament for embodying the idea of the present invention, and the present invention is not limited to the configuration described below. In particular, the materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are merely illustrative examples, and are not intended to limit the scope of the present invention unless otherwise specified. In addition, the size and positional relationship of the members shown in each drawing may be exaggerated for easy understanding.

  The present invention is a nocturnal ornament that is provided in a display unit and effectively uses external light, and the nocturnal member and the ornamental member are arranged in the same region, and regions having different light transmittances are arranged in the same region. By having it, it is possible to draw a gradation pattern, a character, a picture or the like due to a difference in brightness of light emission in a dark place. In a bright place, visibility and decorativeness having a desired metallic feeling and desired color can be imparted. Thus, it is possible to provide a luminescent decoration that imparts graceful visibility and decorativeness, and that makes the white-green color characteristic of the luminescent member inconspicuous.

  In order to realize such a nocturnal ornament, there are roughly three methods for changing the light transmittance in the same region. The first is a method in which a decorative member made of a metal film is formed on a luminous member and a band-like or dot-like opening is provided in the metal film to change the width, size, arrangement density, or the like of the opening. The second is a method of changing the light transmittance by forming a decorative member made of a resin containing a metal film or colored particles on the luminous member and changing the thickness of the metal film or resin. The third is a method of changing the content (density) of colored particles contained in a band-shaped or dot-shaped colored layer made of a resin formed on a luminous member.

  Hereinafter, the luminous decoration will be described in detail with reference to the drawings. First, a method of forming an opening in the first metal film will be described using the first to fifth embodiments. Next, a method of changing the thickness of the colored layer or the content (density) of the colored particles by forming the second and third colored layers is used in the sixth to eighth embodiments (including modifications). I will explain. Next, a method by combination will be described using the ninth and tenth embodiments. In the description, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted. Further, parts not related to the invention are omitted.

  First, the first embodiment will be described with reference to FIGS. 1A and 1B. 2A and 2B, the third embodiment using FIGS. 3A and 3B, and the fourth embodiment (deformation using FIGS. 4A, 4B, and 4C). The fifth embodiment will be described with reference to FIGS. 5A and 5B. Next, the manufacturing process of the first embodiment will be described with reference to FIGS. 6A to 6D, and then another configuration example (three examples) in the first embodiment will be described with reference to FIGS. 7A to 7C. explain. Next, the sixth and seventh embodiments (including modifications) will be described with reference to FIGS. 8A to 8C, and display examples based on a band-like or dot-like brightness difference will be described with reference to FIGS. 9A and 9B. . Moreover, the application example to the pointer type wristwatch of the present invention will be described with reference to FIGS.

[Description of First Embodiment: FIGS. 1A and 1B]
First, the luminescent decoration 150 of the 1st Embodiment of this invention is demonstrated using FIG. 1A and FIG. 1B. FIG. 1A shows a plan view of the luminous decoration 150, and FIG. 1B shows a cross section taken along the line AA ′.

The feature of the first embodiment is that the luminous member 3 and the decorative member 2 are mixedly arranged in the same region by the opening pattern formed in the decorative member 2 when the luminous ornament 150 is viewed from the viewing side. ,
By changing the ratio in which the luminous member 3 and the decorative member 2 are mixed by changing the opening width t of the opening 1 and the width w of the decorative member 2, and having regions having different light transmittances in the same region The point is that a gradation pattern can be drawn by providing a difference in brightness in the light emission of the opening.

[Description of configuration]
In FIG. 1A and FIG. 1B, the luminous ornament 150 has an opening pattern on the upper surface (viewing side) of the rectangular luminous member 3 and is formed of a resin or the like containing a metal film or colored particles. Are laminated with a predetermined thickness. The decorative member 2 has the same outer shape as that of the luminous member 3, and the opening pattern includes a plurality of strip-shaped openings 1, and the opening 1 has the narrowest opening width t at both ends, and from both ends. The width gradually increases toward the center, and the center has the widest opening width t ′. Similarly, the width w (distance between the openings) of the decorative member 2 is appropriately changed from w to w ′. By setting it as such an opening pattern, as for the luminous decoration 150, each opening part 1 has formed the light emission part 9 as a whole. The outer shape and size of the light emitting unit 9 are substantially the same as those of the luminous ornament 150.

Next, in FIG. 1B, the luminous member 3 uses a phosphorescent material made of ceramic or plastic containing ZnS-based or SrAl ₂ O ₄ -based phosphorescent particles, for example, in a plate shape with a predetermined thickness. As will be described later, a phosphorescent layer may be formed by applying or filling a metal, ceramic, or the like serving as a base material with a paint containing phosphorescent particles in a resin binder and drying the coating (FIG. 12B). reference). In addition, the structural example using a base material is mentioned later (refer FIG. 2B).

  The above is an example of the luminous member 3, and the luminous member 3 having a necessary luminescent color can be selected as appropriate according to the application. Further, it is possible to arrange a plurality of luminous members 3 of light emitting colors in one luminous member 150 to emit multicolor light.

  The decorative member 2 laminated on the luminous member 3 is formed by depositing, for example, gold, platinum, chromium, aluminum or the like on the surface of the luminous member 3 by a method such as vacuum deposition or sputtering, and using a photolithography method to form a predetermined member. An opening pattern and a predetermined thickness can be formed. When the decorative member 2 is formed of a resin containing colored particles, the resin containing the colored particles is applied by screen printing, an ink jet printer, or the like to form a predetermined opening pattern and a predetermined thickness. Although the thickness of the decorative member 2 is exaggerated, the actual thickness is not particularly limited. For example, the thickness is about 0.1 μm to several tens of μm, and is appropriately determined in consideration of the metal feeling when visually recognized. It is good to decide. In addition, a thin metallic decorative member 2 having the same opening pattern is formed separately, and a luminescent property is obtained using a transparent adhesive or a transparent adhesive containing phosphorescent particles (hereinafter referred to as “nocturnal adhesive”). A method of joining to the member 3 may be used.

  Further, the surface of the luminous member 3 formed by forming a metal film layer having a predetermined thickness with a predetermined opening pattern by a method such as vacuum deposition or sputtering on the surface of the thin plate-shaped transparent member is used. A method of bonding using an adhesive may also be used. Thus, in the structure using a transparent member, there are a method of adhering the transparent member side to the luminous member 3 and a method of adhering the decorative member 2 side to the luminous member 3, which can be appropriately selected depending on the application. By setting it as such a structure, the decorative member 2 which has the specular gloss which utilized the surface smoothness of the transparent member can be pattern-formed easily. In addition, the specific example of the nocturnal decoration using a transparent member is mentioned later (refer FIG. 12B).

Further, as shown in FIG. 1B, the nocturnal ornament 150 has a structure in which the side surface of the nocturnal member 3 is exposed, so that the outline is emphasized by light leakage from the side surface of the nocturnal ornament 150 in the dark place. It is possible to obtain a light emitting pattern. On the other hand, only a light emitting display on the viewing surface side of the luminescent ornament 150 may be used so as to cover a side surface of the luminescent member 3 using a part of the film layer of the decorative member 2. These can be selected according to the purpose. In addition, the specific example of the structure which covers a side surface is mentioned later (refer FIG. 12B).

[Explanation of visibility and decoration in a light place]
Here, the visibility and decorativeness of the luminous decoration 150 in a bright place will be described. In the configuration like the luminous object 150, when the opening in the opening pattern formed in the decorative member 2 can be visually recognized, the metallic feeling is faded and a white-greenish color peculiar to the luminous member 3 is visible. Problem arises.

  The smaller the opening width t of the opening 1 provided in the decorative member 2 is, the more difficult it is to visually recognize the opening pattern, and the larger the opening width t is, the easier it is to visually recognize the opening pattern. This is related to the visual ability of human eyes, and it is known that visual acuity and focus adjustment ability are related. For example, it has been found that an opening width t that a human with a visual acuity of 1.5 (generally good visual acuity) and a near point of 0.08 m cannot visually recognize in a bright place is less than about 15.5 μm. Here, the near point indicates the ability to adjust the focus, and is a value that changes depending on the age. It is said that the peak is around 10 years old (the ability to adjust is high), and the shortest distance that can be adjusted for that age is 0.08 m. is there. Based on such data, it is desirable that the opening width of the opening pattern provided in the luminous decoration is less than about 15.5 μm. Further, it is known that the width w (distance between the openings) of the decorative member 2 affects the metal feeling, and the metal feeling increases as w increases. By utilizing these characteristics, it is difficult to visually recognize the opening pattern, and visibility and decoration with a metallic feeling can be obtained. At the same time, the white greenish color characteristic of the luminous member can be made inconspicuous.

[Description of visibility and decoration in the dark]
Next, the visibility and decorativeness of the luminous decoration 150 in the dark will be described. In a configuration such as the luminous ornament 150, the brightness of the luminous member 3 is affected by the opening width of the opening pattern formed on the decorative member 2.

  In a dark place, the opening width t in which the luminous member 3 can visually recognize light emission is found to be about 3 μm or more by experiment. Further, it is known that when the opening width t is in a range of about 3 μm or more, the narrower the light emission, the brighter the light emission. Further, the width w (distance between the openings) of the decorative member 2 is also related to the brightness of light emission. The larger the w is, the darker light is emitted, and the smaller w is, the light is emitted brighter. By utilizing these characteristics and forming regions having different light transmittances within the same region, it is possible to obtain a pleasing visibility and decorative property such as drawing a pattern by forming a difference in brightness of light emission.

  In the characteristics in the bright place and the dark place described above, the opening width t of the decorative member 2 is set to a range of about 3 μm to 15.5 μm, and the decorative member width w is appropriately adjusted. In addition, it is difficult for human beings who have good visual acuity and focus adjustment ability to visually recognize the opening widths t and t ′, and it is possible to obtain visibility and decoration with a metallic feeling. Further, in a dark place, it is possible to obtain attractive visibility and decoration such as gradation patterns and characters drawn by the difference in brightness of light produced by different opening widths t and t '.

  Preferably, for the opening widths t to t ′ and the decorative member widths w to w ′, a trial experiment is performed on a desired opening pattern, and the visibility and decoration of light emission in the dark place and the opening pattern in the bright place are determined. It is desirable to check the visibility and decorativeness (metal feeling) and adjust accordingly. The same applies to other embodiments and modifications described below. In addition, although the range of the opening width t has been described as about 3 μm to 15.5 μm, it is not limited to this and may be set to 3 μm to 15.5 μm as a guide.

[Description of operation]
In a bright place, external light incident from the upper surface side of the decorative member 2 is incident on each opening 1 (opening width is t to t ′) provided in the decorative member 2 and exposing the luminous member 3 and absorbed. Is done. And the luminous member 3 which absorbed the optical energy of external light will be in an excited state. In the dark where the external light is blocked, the luminous member 3 emits light slowly in the process of returning from the excited state to the ground state. Such a nocturnal ornament 150 has areas having different light transmittances in the same area by setting the opening width t to about 3 μm to 15.5 μm. Displays a vertically striped gradation pattern in which light is emitted darkly, light is emitted brightly in the opening 1 having a wide opening width t ′, and light is emitted in the center and brightly at both ends.

[Description of effects]
The luminous ornament 150 of the first embodiment described above can be applied to a wristwatch, a portable electronic device, various instruments, and the like. For example, if the display part of a wristwatch is taken as an example, it can be applied to a dial, time letters, hands, a symbol logo, a symbol mark, and the like. Since the decorative member 2 and the luminous member 3 are mixedly arranged in the same region and the ratio in which the decorative member 2 and the luminous member 3 are mixed can be changed by the strip-shaped opening 1, the narrow opening 1 in the dark place can be changed. Emits light darkly, and the wide opening 1 can emit light brightly. Thereby, a gradation pattern etc. can be drawn using a light-dark difference. In a bright place, the opening pattern formed in the decorative member 2 is difficult to visually recognize, so that it is recognized as a decorative object having a square metallic feeling, and the white-green color characteristic peculiar to the luminous member can be made inconspicuous. As a result, the white greenish color characteristic of the luminous member 3 is not conspicuous in the bright place and is recognized as a decorative object with a metallic feeling, and the ratio of the decorative member 2 and the opening 1 mixed is changed in the dark place. Thus, it is possible to provide a luminous decoration 150 that creates a light / dark difference in light emission of the luminous member 3 and imparts graceful visibility and decorativeness.

  The opening pattern of the luminous ornament 150 has been described as a bright gradation pattern at the center, but is not limited to this, and may be a gradation pattern with bright ends or a gradation pattern that changes freely. The opening pattern has been described as a band-shaped opening, but is not limited thereto, and for example, a circular gradation pattern using the ring-shaped opening 1 may be used. Moreover, although the external shape of the nocturnal decoration 150 was demonstrated with the rectangular shape, it is not limited to this, A triangle, a polygon, a circle | round | yen, etc. may be sufficient. Further, the light / dark difference may be controlled by changing the light transmission amount in the same region by controlling the thickness of the decorative member 2.

  Further, the luminous decoration 150 can be applied to a dial plate, a time character, a pointer, a symbol logo, a symbol mark, and the like by taking a display part of a wristwatch as an example. It can also be applied to. Moreover, although the example which makes the external shape of the nocturnal ornament 150 and the shape of the light emission part 9 the substantially same magnitude | size was demonstrated, it is not limited to this, You may make it a different magnitude | size according to the objective.

Here, although not particularly limited, main metal materials used for the decorative member 2 are listed. For example, gold, silver, platinum, chromium, and aluminum. Moreover, although it does not specifically limit, the material used for the luminous member 3 is mention | raise | lifted. For example, it is a ZnS-based or SrAl ₂ O _4- based pigment, and the emission color is not particularly limited, but may be blue-green, yellow-green, yellow, or orange.

[Description of Second Embodiment: FIGS. 2A and 2B]
Next, the luminous ornament 155 which is 2nd Embodiment is demonstrated using FIG. 2A and FIG. 2B. 2A shows a plan view of the luminous ornament 155, and FIG. 2B shows a BB ′ cross section of the main part thereof.

The feature of the luminous ornament 155 of the second embodiment is that the luminous member 3 having an outer shape different from that of the decorative member 2 is laminated on the base material 4 together with the filling member 6 to form a gradation pattern in a free shape. It is a point that can draw. Since the other basic configuration of the luminescent ornament 155 is the same as that of the luminescent ornament 150, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 2A and FIG. 2B, as for the luminous ornament 155, the decorative member 2 similar to the above-mentioned luminous ornament 150 is formed in the visual recognition side. Moreover, the luminous member 3 is formed in the space sandwiched between the decorative member 2 and the base material 4 with a predetermined thickness by taking a donut shape as an example, for example, by screen printing. For example, in order for the luminous member 3 to emit light sufficiently brightly in a dark place, it may be formed with a thickness of about 200 μm to 300 μm. Further, the space around the luminous member 3 (including the central portion) sandwiched between the decorative member 2 and the base material 4 is a filling member made of a resin or paint containing a pigment of the same color as the luminous member 3 6 is filled. This is to make the color of the luminous member 2 less noticeable by disposing the similar-colored filling member 6 around the white-green color characteristic of the luminous member 2. Here, although not particularly limited, materials used for the filling member 6 are listed. For example, epoxy resin, urethane resin, acrylic resin and the like.

  The luminous member 3 exposed in each opening 1 of the decorative member 2 forms a donut-shaped light emitting portion 9 so that the opening widths t to t ′ narrow from the center of the luminous ornament 155 toward the left and right. It is set to about 3 μm to 15.5 μm. As a result, the light emitting section 9 emits light in a donut shape in a dark place, emits light brightly at the wide opening 1 near the center, and emits light darkly at the narrow opening 1 near both ends, thereby forming a light / dark difference. Further, since it is difficult to visually recognize the opening pattern in a bright place, a metallic feeling can be obtained, and the white-green color characteristic peculiar to the luminous member 3 can be made inconspicuous.

  As described above, the luminous ornament 155 of the second embodiment forms a light / dark difference of light emission by changing the opening width t of the band-like opening 1 having a shape different from the shape of the pattern that emits light in a dark place. At the same time, the luminous shape can be changed to an arbitrary shape by forming the luminous member 3 in a shape different from the outer shape of the luminous ornament 155. Thereby, the nocturnal ornament 155 which provided the pattern which made the gradation light emission to arbitrary shapes in the dark place, and provided the attractive visibility and decorating property can be provided. Further, in the bright place, it is possible to provide a luminescent ornament 155 that has a metallic vividness and a decorative property, and in which the white-green color characteristic of the luminescent member 3 is inconspicuous.

  The luminous decoration 155 has a desired light emission shape by making the luminous member 3 a predetermined shape. However, in the luminous decoration 150 described above, the opening pattern of the decoration member 2 has a desired light emission. The same effect can be obtained by adopting a shape. Moreover, although the light emission part 9 provided in the luminous ornament 155 demonstrated the example light-emitted in donut shape, it is not limited to this, A character, a symbol, and other arbitrary shapes may be sufficient. Moreover, although the external shape of the nocturnal ornament 155 demonstrated rectangular shape, it is not limited to this, A polygon, circular, etc. may be sufficient. Here, although not particularly limited, materials used for the substrate 4 are listed. For example, metal such as stainless steel, ceramic, resin, glass and the like.

  As described above, the luminous ornament 160 is provided with a wide opening part in each band-like narrow opening, so that the narrow opening t1 emits light in the dark and the wide opening t2 emits light brightly. Therefore, a light / dark difference can be formed in the light emitting portion 9. In the bright place, the opening pattern formed in the decorative member 2 is difficult to visually recognize, so that a metallic feeling can be obtained, and the white-green color characteristic of the luminescent member can be made inconspicuous. Thereby, since a character, a symbol, a shape, etc. can be drawn in a dark place, the nocturnal decoration which provided the attractive visibility and decoration which differ from a bright place can be provided. Further, in a bright place, it is possible to provide a luminescent ornament that has a visibility and decoration with a metallic feeling, and that does not make the white-green color characteristic of the luminescent member inconspicuous.

  In addition, although the example in which the nocturnal decoration 160 light-emits number "4" was demonstrated, it is not limited to this, Another character, a symbol, and another free shape may be sufficient. Moreover, although the external shape of the nocturnal ornament 160 was demonstrated with the rectangular shape, it is not limited to this, A polygon, a circle | round | yen, etc. may be sufficient. Further, in the opening pattern of the decorative member 2, the opening pattern can be averaged by regularly mixing the narrow opening with the wide opening forming the character or the like, so that it is more difficult to visually recognize the opening pattern in a bright place. It is effective in doing. Further, by making the narrow opening width t1 smaller than about 3 μm, it is possible to further increase the contrast between light and dark and make the characters stand out. These effects can be similarly obtained in other embodiments described below.

To do. The luminous member 3 emits light that passes through the decorative member 2 from the lower surface side of the decorative member 2 and scatters by colliding with the colored particles. In the decorative member 2, the thick part where the number of collisions with the colored particles is large has low light transmittance and thus emits light darkly, and the thin part where the number of collisions is small has high light transmittance and emits brightly. As a result, in a dark place, when viewed from the upper surface side of the decorative member 2, it is possible to create a light-dark difference in which the central portion is bright and gradually darkens toward both ends when viewed from the top (see FIG. 9A described later). Further, by using a resin in which predetermined colored particles are blended, it is possible to have a desired metal feeling or color in characters, shapes, patterns, etc. in a bright place. For example, when aluminum particles of metal particles are used, a silver metal feeling can be obtained, and when titanium dioxide of pigment is used, white can be obtained. Further, the texture may be changed by changing the size of the colored particles.

[Description of effects]
The luminescent ornament 200 is a luminescent ornament that effectively uses external light, and in the dark place, a bright region and a dark region of light emission of the luminescent member are formed in the same region in a band shape or a dot shape. Can do. Thereby, since a gradation pattern, a character, a pattern, etc. by the light-emission brightness difference can be drawn, the nocturnal decoration which provided the glaring visibility and decoration property can be provided. Also, in a bright place, it is possible to draw letters, shapes, designs, etc. having a desired metallic feeling and color, and to provide a luminescent decoration that makes the white-green color characteristic of a luminescent member inconspicuous Can do. Further, since the transparent member 5 acts as a light guide plate, it can efficiently receive external light in a bright place and can efficiently emit a nocturnal member in a dark place.

  The decorative member 2 can be formed by printing a resin layer a predetermined number of times on the upper surface of the luminous member 3 formed in a step shape by using, for example, a screen printing method or a tampo printing method. In this example, the decorative member 2 has a thin central portion and is formed thick in a stepped shape toward both end portions. However, the present invention is not particularly limited. For example, the decorative member 2 may have a structure in which the central portion is thick and both end portions are thin. Further, although it is stepped, it may be formed in a slope shape. Here, main resins used for the decorative member 2 are listed. Although not specifically limited, it is an epoxy resin, a urethane resin, an acrylic resin, or the like. In addition, main colored particles to be blended in the decorative member 2 are listed. Although not particularly limited, when metal particles are used, for example, aluminum, brass, zinc sulfide and the like are used. Moreover, when using a pigment, they are carbon black, titanium dioxide, iron oxide, chrome lead, etc. In addition, by using a predetermined pigment for the colored particles, a desired color can be obtained in a dark place in addition to the difference in brightness of light emission.

[Explanation of Modification in Sixth Embodiment: FIG. 8B]
Next, the luminous decoration 205 of the modification in 6th Embodiment is demonstrated using FIG. 8B. FIG. 8B shows a cross-sectional view of the luminous decoration 205.

  The feature of the luminous ornament 205, which is a modified example of the sixth embodiment, consists of a colored layer containing colored particles in the resin on the surface of the luminous member 3, like the luminous ornament 200 described above. The decorative member 2 is formed, and regions having different light transmittances are provided in the same region, but the luminous member 3 is different from the luminous ornament 200 in the space corresponding to the transparent member 5 where the luminous member 3 is a staircase. It is the point formed and filled in the shape. Since the other basic configuration of the luminescent ornament 205 is the same as that of the luminescent ornament 200, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 8B, the luminous member 205 has the decorative member 2 made of resin on the upper surface (viewing side) of the luminous member 3. In addition, the lower surface side of the decorative member 2 has a step-like recess inside, and the thickness of the resin layer changes for each step. The thickness of each stepped part of the resin layer is a predetermined thickness, but since the colored particles are uniformly dispersed in the resin, the thick part has low light transmittance, and the thin part The light transmittance is high. Further, since the luminous member 3 is filled and formed in the concave portion on the lower surface side of the decorative member 2, the luminous member 3 can increase the light emission amount near the center. Thereby, compared with the nocturnal ornament 200, the central portion emits light more brightly in a dark place, so that the difference in light intensity can be increased.

[Description of seventh embodiment (example of changing content of colored particles): FIG. 8C]
Next, the luminous decoration 210 of 7th Embodiment is demonstrated using FIG. 8C. FIG. 8C shows a cross-sectional view of the luminous decoration 210.

However, the colored layer is formed of a plurality of strip-shaped colored layers with a uniform thickness, and the colored layer has different light transmittance by changing the content (density) of colored particles for each strip. This is the point where the region is formed. Since the other basic configuration of the luminescent ornament 210 is the same as that of the luminescent ornament 200, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 8C, the luminous decoration 210 has a plurality of strip-shaped decorative members 2 made of resin formed in parallel on the upper surface (viewing side) of the luminous member 3 to have the same thickness. Here, the colored particles in the resin of the plurality of strip-shaped decorative members 2 are respectively mixed at a predetermined content rate. For example, the content rate of the central decorative member 2 is the lowest (low density), and the decorative members 2 on both ends are provided. It is compounded so that the content rate becomes higher (high density) step by step. As a result, the light transmittance decreases stepwise from the central portion toward both ends, and a brightness difference can be created (see FIG. 9A described later). In addition, it can have a desired color in a bright place by performing predetermined coloring to each strip | belt-shaped decoration member 2 using the characteristic color which a colored particle has.

Next, the information display unit 120a of the wristwatch 500 will be described with reference to FIG. 11A. The information display unit 120a shows how the display unit looks in a bright place. The information display unit 120a is provided with the luminous decorations of the present invention at important points, and the time letters 115a, 116a, and 117a are arranged on the dial plate 106 (for example, white) so that the time can be displayed. ing. A symbol logo 118a, a symbol mark 119a, and a picture 211a are also arranged.

  In the information display unit 120a, the time characters 115a, 116a, and 117a are outer peripheral portions of the dial plate 106, and are arranged at predetermined angular intervals in the circumferential direction inside the parting member 108 (see FIG. 10). . Here, two time letters 116a indicating 12 o'clock are arranged so that they can be distinguished from other time letters. For example, by applying the structure of the luminous ornament 160, 165 or 170 described above, Is formed. The time character 116a is a substantially rectangular parallelepiped having the decorative member 2 on the surface and having a metallic feeling, and is fixed to a predetermined position on the upper surface of the dial 106 by a method such as caulking or bonding. Next, the time letters 115a indicating 1 o'clock, 2 o'clock, 4 o'clock, 5 o'clock, 7 o'clock, 8 o'clock, 10 o'clock, and 11 o'clock are formed by applying, for example, the configuration of the above-mentioned luminous decoration 150. . The time character 115a is provided with a decorative member 2 on the surface, has a metallic feeling and is a substantially rectangular parallelepiped having substantially the same size as the time character 116a, and is fixed to a predetermined position on the upper surface of the dial 106 by a method such as caulking or bonding. Has been. Next, the time letters 117a at 3 o'clock, 6 o'clock, and 9 o'clock are formed, for example, by applying the configuration of the above-described nocturnal ornament 160, 165, or 170. The time character 117a is provided with a decorative member 2 on the surface, has a metallic feeling, and can be visually distinguished from other time characters by making it a substantially rectangular parallelepiped having a slightly different shape from the time character 116a or 115a. It is fixed to the upper surface of the dial 106 by, for example, caulking or bonding.

Further, a symbol logo 118a is arranged below the 12 o'clock hour character 116a of the dial 106. The symbol logo 118a uses, for example, the configuration and the opening pattern of the above-mentioned nocturnal ornament 150, and is exemplified here as a convex “ABC”, for example. Further, a symbol mark 119a is arranged above the 6 o'clock time character 117a. The symbol mark 119a uses, for example, the configuration of the luminous ornament 185 and the opening pattern of the luminous ornament 150 described above, and is exemplified here as a convex “vertical stripe pattern having a circular outer shape”, for example. . In addition, the pattern 211a is a reproduction of the “cube” described in the luminous ornament 211 in FIG. 9B using, for example, the configuration of the luminous ornament 211. Here, for example, the pattern 211a is displayed with a broken line because it is difficult to visually recognize the colored particles in a bright place by making the colored particles the same color as the dial (for example, white). Note that the luminous ornament 211 described above has different light transmittances of the decorative member 2 in the region corresponding to each surface of the cube and the periphery thereof, so that the three-dimensional shape of the cube can be easily seen. The difference in brightness of the luminous member 3 is given by the difference.

[Description of Information Display Unit 120b in the Dark: FIG. 11B]
Next, the information display unit 120b in the dark place of the wristwatch 500 will be described with reference to FIG. 11B. The information display unit 120b shows how the information display unit 120a in the above-mentioned bright place looks in a state where external light such as nighttime is blocked. In each nocturnal ornament arranged in the information display unit 120b, the nocturnal member 3 absorbs the light energy of external light in a bright place and is in an excited state. In the dark where the external light is blocked, the luminous member 3 emits light slowly in the process of returning from the excited state to the ground state.

  In the information display unit 120b, the two hour letters 116b at 12 o'clock were visually recognized as two substantially rectangular parallelepipeds having a metallic feeling in a bright place, but in the dark place, the width of the opening 1 was changed to be different. “1” and “2” are displayed by creating the light / dark difference of light emission. Further, the outer shape of the two time letters 116b is visually recognized as “12” because it is difficult to visually recognize as indicated by a broken line in a dark place. Similarly, the time letters 117b at 3 o'clock, 6 o'clock, and 9 o'clock are displayed as “3”, “6”, and “9” and are visually recognized. Next, the time letters 115b at 1 o'clock, 2 o'clock, 4 o'clock, 5 o'clock, 7 o'clock, 8 o'clock, 10 o'clock and 11 o'clock were similarly recognized as a substantially rectangular parallelepiped having a metallic feeling in the light, but the light emission Is displayed in a “small rectangle” and is visually recognized. As described above, each time character was visually recognized as a substantially rectangular parallelepiped with a metallic feeling in a bright place, but changed into a number or a small rectangle in a dark place, and thus emitted light, giving a graceful visibility and decorativeness. be able to. In particular, the time at 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock are displayed as numbers by light emission, so that the time can be accurately and instantly recognized together with the hands. Further, the symbol logo 118a is visually recognized as a convex character “ABC” having a metallic feeling in a bright place, but is changed to a gradation character “ABC” due to light emission and is visually recognized as a tasteful display. Further, the symbol mark 119b was visually recognized as a “vertical vertical striped pattern with a circular outer shape” in a bright place, but changed to a “vertical vertical striped pattern with a circular outer shape” by light emission as a quaint display. Visible. In addition, the pattern 211b is assimilated to a dial plate in a bright place and is difficult to visually recognize, but it can be visually recognized as a “cube” by a display using the difference in brightness of light emission. In the light place, the pattern 211a is illustrated in a similar color to the dial (for example, white) to make it difficult to visually recognize, but other colors that can be visually recognized may be provided.

In this way, by applying the luminous decoration of the present invention to time points, pointers, symbol logos, symbol marks, designs, etc., and placing them at key points, the watch 500 can only notify the time in the dark. In addition, the luminous member 3 emits numbers, letters, gradation patterns, shapes, patterns, and the like having desired colors, and can be provided with attractive visibility and decoration. In addition, in the bright place, visibility and decoration that can draw letters, shapes, patterns, etc. with the desired metallic feeling and desired color are given, and the white-green color characteristic of the luminous member is conspicuous Lost luminescent decoration can be provided. Note that the design 211b employs the luminous decoration 211 having a configuration in which the light transmittance of each surface of the cube and its surroundings is different, but adopts the configuration of the luminous decoration 200 or the luminous decoration 210. Or you may employ | adopt the nocturnal decoration 166 using the opening part. Moreover, although the example which employ | adopted "cube" as the dial was demonstrated, for example, it can employ | adopt as a symbol logo, a symbol mark, and any other pictures.

[Explanation of Symbol Logo 118: FIGS. 12A and 12B]
Next, the symbol logo 118 will be described with reference to FIGS. 12A and 12B. 12A shows a perspective view of the symbol logo 118, and FIG. 12B shows a GG ′ cross section of the main part thereof.

  The feature of the symbol logo 118 is that the symbol logo is formed on the base material 4. For example, a convex character “ABC” is shown as an example. In addition, by applying the configuration and opening pattern of the luminous decoration 150 described above and using the transparent member 5 between the luminous member and the decorative member, it is possible to adjust the gradation pattern and emission color in a dark place. It is what.

  In FIG. 12A, the symbol logo 118 forms convex characters on the base material 4 and is exemplified here as “ABC”. The character is not particularly limited, and a free character or the like can be formed as a symbol logo. The symbol logo 118 is fixed to a predetermined position on the dial 106 (see FIG. 11A) by a method such as caulking or bonding. Next, in FIG. 12B, a convex part is formed on the base material 4, and a concave part 12 is formed on the upper surface thereof. In the concave portion 12, for example, a paint containing phosphorescent particles in a resin binder is filled and formed, and dried to form the luminous member 3 flat. A transparent member 5 is bonded to the surface of the luminous member 3 with a transparent adhesive or a luminous adhesive. The decorative member 2 is laminated on the surface of the transparent member 5 by vapor deposition or sputtering. Here, the opening pattern formed in the decorative member 2 changes from t to t ′ from the both end sides where the width of the opening 1 is the narrowest, so that the central portion is the widest opening t ′. Further, the width of the decorative member 2 changes from w to w ′ from both ends.

  As described above, the symbol logo 118 has the decorative member 2 and the luminous member 3 mixedly disposed in the same region, and the opening width t of the opening pattern formed on the decorative member 2 is about 3 μm to 15.5 μm. Since it is set, in a dark place, light is emitted darkly with a narrow aperture width, and light is emitted brightly with a wide aperture width. Thereby, in a dark place, it is possible to draw a gradation pattern in which the central portion of the letter “A” emits bright light in vertical stripes and both ends of “A” emit light dark in vertical stripes. The same applies to the characters “B” and “C”. In a bright place, the opening pattern formed in the decorative member 2 is difficult to visually recognize, so that it has a metallic feeling and can make the white-green color characteristic of the luminescent member inconspicuous. As a result, the symbol logo 118 has a quaint visibility and decoration by a gradation pattern in a dark place, and has a visibility and decoration with a metallic feeling in a light place and a white-green color characteristic of a luminous member. The color can be made inconspicuous.

Note that, by coloring the transparent member 5 in the symbol logo 118, the emission color peculiar to the luminous member 3 can be adjusted. For example, the luminous color of the luminous member 3 that emits light can be obtained by using a transparent member such as acrylic or polycarbonate, or a transparent member containing glass containing a dye, pigment, phosphor, or a composite thereof. Can be changed. For example, when a phosphor (Ca _1.2 Eu _0.8 SiO ₄ ) is used for the transparent member 5, 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). It can be. Further, although not particularly limited, light may be emitted in other colors using other phosphors, dyes, and pigments. In addition, a dielectric film or the like may be formed in multiple layers on the surface of the transparent member 5 to change the emission color using light interference.

  Further, the symbol logo 118 can easily form a mirror-like glossy metal film by making use of the surface smoothness of the transparent member 5, and the polishing process of the decorative member can be omitted. Moreover, since the transparent member 5 acts as a light guide plate, external light taken from each opening in a bright place can be uniformly absorbed by the entire luminous member, and the luminous efficiency is improved and the light emission time can be extended. Further, the symbol logo 118 has a structure in which the side surface of the transparent member 5 is covered with a part of the decorative member 2 in the cross-sectional view shown in FIG. 12B, but light leakage from the side surface of the transparent member 5 is used without covering the side surface. The outline of the character may be emphasized.

[Explanation of Symbol Mark 119: FIGS. 13A and 13B]
Next, the symbol mark 118 will be described with reference to FIGS. 13A and 13B. FIG. 13A shows a perspective view of the symbol mark 119, and FIG. 13B shows a HH ′ cross section of the main part thereof.

  The feature of the symbol mark 119 is that the plate-shaped decorative member 2 is provided with a convex “symbol mark shape”, and for example, a “vertical stripe pattern” composed of a plurality of striped portions is exemplified. A stepwise gradation pattern is made possible by changing the width of the band-like opening stepwise.

  In FIG. 13A, the symbol mark 119 includes a plurality of vertical stripes (n to n ′) arranged on the decorative member 2 made of a metal such as gold, silver, and chrome so that the outer shape is circular using an etching method or the like. ) In a convex shape. In FIG. 13B, an opening pattern is formed on the upper surface of each vertical stripe, and each opening 1 has a belt-like groove having an opening width (t1 to t4) and a decorative member width (w1 to w4). Moreover, the luminous member 3 is filled and formed in each opening 1 with a squeegee or the like and dried and solidified. Here, the opening width formed in the vertical stripe k in the central portion is the widest t1, and the opening width is t1 to t2 in the order of l, m, n (or l ′, m ′, n ′). It becomes narrower sequentially with t4. Similarly, the decorative member width w is appropriately changed from w1 to w4.

  As described above, the symbol mark 119 is arranged such that the decorative member 2 and the luminous member 3 are mixed in the same region, and the opening pattern formed in the decorative member 2 is set to about 3 μm to 15.5 μm. Therefore, in a dark place, the vertical stripe k having a wide opening emits the brightest light, and the light emits darker as it approaches the vertical stripe n at both ends having a narrow opening. Accordingly, it is possible to draw a gradation pattern in which the vertical stripe (k) in the central portion emits the brightest light and gradually darkens toward both end sides (n, n ′). Also, in the bright place, the opening pattern formed in the decorative member 2 is difficult to visually recognize, so that it has a high-grade metallic feeling such as gold, silver, chrome, etc., and the white greenish color peculiar to the luminous member is inconspicuous can do. As a result, the symbol mark 119 has a graceful visibility and decoration by a gradation pattern in a dark place, and has a visibility and decoration with a desired metallic feeling in a bright place and a white-green color peculiar to a luminous member. The color of the system can be made inconspicuous.

  The symbol mark 119 can be displayed in a stepwise brightness by forming the band-like opening 1 stepwise in the opening width (t1 to t4). For example, the above-described nocturnal decorative member 165 ( By applying (see FIG. 4A) and increasing the size of the square hole from, for example, two types to four types, it is possible to express gradation display with four levels of brightness. Thus, by applying the opening pattern of the luminous decoration member 165 and increasing the number of gradations, a more complicated and elegant pattern can be expressed. Such a luminous decoration capable of gradation display is not limited to the wristwatch symbol mark, and can be provided anywhere on the display portion.

  The symbol logo and the symbol mark may be formed as a separate member from the dial and fixed at a predetermined position by caulking or bonding, but may be integrated with the dial at a predetermined position of the dial. Or the entire dial may be used as the luminous ornament of the present invention.

  As described above, in the luminous ornament, there are roughly three methods for forming regions having different light transmittances in the same region, and each method has been described based on the embodiment. Thereby, in a dark place, since it is possible to draw a gradation pattern, a character, a pattern, and the like having light emission contrast and color, it is possible to provide a nocturnal decoration with a graceful visibility and decorativeness. In addition, in the bright place, visibility and decoration that can draw letters, shapes, patterns, etc. with the desired metallic feeling and desired color are given, and the white-green color characteristic of the luminous member is conspicuous Lost luminescent decoration can be provided.

  Although various embodiments and configuration examples and application examples of the luminous ornament are described in detail, the present invention is not limited to such embodiments, configuration examples or 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. In particular, it finds value in reading beauty and information correctly, it requires visibility and decoration with a desired metallic feeling and desired color in bright places, and changes light transmittance and darkness by changing light transmittance in dark places.
