As a display device that is a decorative product using light, Patent Document 1 describes a 3D image printed on the back surface of an acrylic plate by illuminating the 3D image printed on the back surface of the acrylic plate with an LED to obtain a three-dimensional image on the front surface of the acrylic plate. A display device that emerges is disclosed.

Japanese Unexamined Patent Publication No. 2013-120340

However, as a technical idea relating to the light illumination method of the display device described in Patent Document 1, what is printed on the back surface of the acrylic plate is simply illuminated from the back surface side of the acrylic plate. It was to make it emerge. Therefore, if the 3D image is not printed on the acrylic plate, the image on the back surface side (decorative portion) is simply projected on the front surface side, and the design effect is low.
On the other hand, in the field of painted products using lacquer, which is a traditional Japanese craft, it was required to create a new design appeal.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a decorative product having a decorative portion by painting with enhanced design effect by light, and a method for manufacturing the decorative product.
Another object of the present invention is to provide a decorative item which can be improved in appearance by having a decorative portion even in a state where it is not irradiated with light.

According to the decorative product according to the present invention, the subject is a decorative product that emits light from a light source radiated from the back surface side to the front surface side, and is a transparent base material having translucency provided on the back surface side. A first decorative portion painted on the surface side of the transparent base material, a light guide layer having translucency formed on the surface side of the first decorative portion, and the surface of the light guide layer. The light guide layer comprises a surface layer having a second decorative portion formed on the side, and the light guide layer emits light emitted from the light source through the transparent substrate at a position facing the transparent substrate. The surface layer has a light guide portion having a light-transmitting property that guides the light guide to the surface side, and the surface layer has a light emitting portion that emits light that has passed through the light guide layer from the light guide portion to the surface side. The decorative portion is formed at a position where it overlaps at least a part of the light guide portion in the front and back directions, and in the front and back directions, the boundary between the first decorative portion and the light guide portion in the direction perpendicular to the front and back directions. It is solved by being formed in the vicinity of.

According to the above configuration, the second decorative portion is formed at a position where it overlaps at least a part of the light guide portion in the front and back directions, and is perpendicular to the front and back directions of the first decorative portion and the light guide portion in the front and back directions. Since it is formed near the boundary of the direction, the light emitted from the light source is emitted from the emission portion avoiding the second decorative portion, so that the amount of light emitted from the surface layer and the emission location are limited. .. Then, when a part of the second decorative portion is irradiated with light, it becomes three-dimensionally raised, and it is possible to provide a decorative product having an enhanced design effect.

Further, it is preferable that a part of the second decorative portion is formed at a position overlapping at least a part of the boundary in the front-back direction.
According to the above configuration, a part of the second decorative portion is formed so as to overlap at least a part of the boundary, so that direct light is directed to the surface side from the light guide portion inside the boundary in that portion. It is possible to prevent the radiation from being emitted, and by indirectly illuminating the second decorative portion, the design effect due to the indirect light can be enhanced.

Further, the boundary may be formed inside the outer periphery of the second decorative portion.
According to the above configuration, it is possible to enhance the three-dimensional visual effect by suppressing the irradiation light from the light source from coming into direct contact with the eyes from the surface side and using indirect illumination. Further, when the light is not emitted from the light source, the boundary between the first decorative portion and the light guide portion can be prevented from being exposed on the surface side, and the appearance can be improved.

Further, it is preferable that the emission unit or the light guide layer is made of UV paint.
According to the above configuration, since the emission portion or the light guide layer is made of UV paint, the drying time can be shortened and the emission portion can be thickly coated, so that the emission portion or the light guide layer can be formed. The number of intermediate coatings can be reduced. Further, since the UV coating material can shorten the drying time by irradiating with ultraviolet rays, it is possible to suppress the occurrence of unevenness in the thickness of the emitting portion or the light guide layer, and it is possible to form these thinly.

Further, the first decorative portion may have a light-shielding property.
According to the above configuration, the first decorative portion suppresses the transmission of light, so that the second decorative portion can be further raised.

Further, the second decorative portion may have a lacquer work on the surface side thereof.
According to the above configuration, since the second decorative portion is provided with the lacquer treatment on the surface side, the lacquer treatment can be made conspicuous by the light emitted from the emission portion, and the design can be further enhanced.

Further, the second decorative portion may have a light-shielding property.
According to the above configuration, by suppressing the transmission of light in the second decorative portion, the lacquer work or the like applied to the surface side of the decorative item can be further highlighted.

Further, the second decorative portion may have light reflectivity.
According to the above configuration, since the second decorative portion has light reflectivity, the amount of light emitted from the emitting portion, which is another portion of the second decorative portion, can be increased.

Further, according to the method for manufacturing a decorative product according to the present invention, the subject is a method for manufacturing a decorative product that emits light from a light source irradiated from the back surface side to the front surface side, and is provided on the back surface side. A transparent base material having translucency is prepared, a first decorative portion is applied to the surface side of the transparent base material, and a light guide layer having translucency is formed on the surface side of the first decorative portion. Then, a second decorative portion is applied to the surface side of the light guide layer to form a surface layer, and when the light guide layer is formed, the light source is placed at a position facing the transparent base material. When the light guide portion that guides the light emitted through the transparent substrate to the surface side is formed and the surface layer is formed, the light guide portion in the first decorative portion and the light guide portion is formed in the front and back directions. The problem is solved by applying the second decorative portion to a position near the boundary in the direction perpendicular to the front and back directions and overlapping at least a part of the light guide portion in the front and back directions.

According to the above configuration, when the surface layer is formed, it is in the vicinity of the boundary between the first decorative portion and the light guide portion in the direction perpendicular to the front and back directions in the front and back directions, and is at least a part of the light guide portion. By manufacturing the decorative product by applying the second decorative portion to the overlapping positions in the front and back directions, it is possible to limit the amount of light emitted from the surface layer and the emission location in the manufactured decorative product. Then, when the second decorative portion is irradiated with light, it becomes three-dimensionally raised, and it is possible to provide a method for manufacturing a decorative product with an enhanced design effect.

According to the present invention, it is possible to provide a decorative product having a decorative portion by painting with enhanced design effect by light.
Further, according to the present invention, it is possible to enhance the three-dimensional visual effect while thinning the decorative item, and further, in a state where the light source does not irradiate the decorative item, the first decorative portion is provided on the surface side of the decorative item. It is possible to prevent the boundary with the light guide portion from being exposed and improve the appearance.
Further, according to the present invention, the number of times of intermediate coating for forming the emission portion or the light guide layer can be suppressed.
Further, according to the present invention, the second decorative portion can be further raised.
Further, according to the present invention, the designability can be changed more effectively depending on the presence or absence of light.
Further, according to the present invention, the lacquer work can be made conspicuous by the light emitted from the emitting portion, and the design can be further enhanced.
Further, according to the present invention, it is possible to increase the amount of light emitted from the emitting portion, which is another portion of the second decorative portion.
Further, according to the present invention, it is possible to provide a method for manufacturing a decorative product having a decorative portion by painting with enhanced design effect by light.

The present invention relates to a decorative item and a method for manufacturing the decorative item, and more particularly to a decorative item using light and a method for manufacturing the decorative item.
Hereinafter, the decorative products 1, 1a according to the embodiment of the present invention will be described.
In the embodiment described below, the side with the lacquer portion 5b and the top clear portion 5c (upper side in FIG. 2) is the surface side of the decorative items 1, 1a, and the side with the transparent base material 2 (lower side in FIG. 2). ) Will be described as the back surface side of the decorative items 1, 1a.
Further, the embodiments described below are merely examples for facilitating the understanding of the present invention, and do not limit the present invention. That is, the shapes, dimensions, arrangements, and the like of the members described below can be changed and improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.

(About the composition of decorations)
First, the configuration of the decorative item 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. It should be noted that FIG. 1 is a view showing the surface of the decoration product 1 according to the embodiment of the present invention, and is a plan view showing a state in which light is not irradiated, and FIG. 2 shows a cross section of II-II of FIG. It is a sectional view.
The decorative item 1 according to the present embodiment is decorated with a goldfish as shown in FIG. 1 by the lacquer work portion 5b described later. The goldfish-decorated lacquer lacquer portion 5b is formed so as to emerge from the background coating portion 3a as shown in FIG. 3 by the light emitted from the LED 8 described later on the back surface side.

The decorative item 1 according to the present embodiment has a laminated structure, and as shown in FIG. 2 in detail, a transparent base material 2, a background coating portion 3a coated on the transparent base material 2, and a background coating portion. It is mainly composed of a light guide layer 4 coated on 3a and a surface layer 5 coated on the light guide layer 4.

The transparent base material 2 is a plate material made of translucent polycarbonate and having a thickness of about 3 mm, and is a base member to be coated with the background coating portion 3a. In particular, if the transparent base material 2 is made too thin, the rigidity becomes low. Then, when the transparent base material 2 is bent, it is necessary to suppress the occurrence of cracks or the like in the background coating portion 3a and the lacquer portion 5b, which will be described later. Therefore, the transparent substrate 2 preferably has a thickness of about 3 mm or more.
On the other hand, if the transparent base material 2 is adhered or fixed to other members so as to limit the deformation of the transparent base material 2 so as not to affect the background coating portion 3a and the lacquer work portion 5b, the transparent base material 2 is used. It is also possible to thin the material 2 into a film.

The transparent base material 2 is not limited to one made of polycarbonate as long as it has translucency. For example, the transparent base material 2 may be a resin film such as acrylic, AES (Acrylonitrile Ethylene Styrene), PVC (Poly Vinyl Chloride), or a glass plate.

On the surface side of the transparent base material 2, a colored background coating portion 3a applied to the surface side of the transparent base material 2 and a portion facing the transparent base material 2 but not coated with the background coating portion 3a. A light guide layer 4 having a light guide portion 4x and having translucency is formed. The background coating portion 3a corresponds to the first decorative portion according to the present invention, is a portion painted with a colored paint, and has a film thickness of about 1 mm or less.

The light guide layer 4 emits light from the LED 8 on the back surface side while forming a space having translucency between the light-shielding / reflective layer 5a (and the lacquer portion 5b) described later and the background coating portion 3a in the thickness direction. It has a function of guiding light so that the emitted light is emitted from the surface. The light guide layer 4 is an intermediate coating layer formed of a translucent polyester-based clear paint or the like. In particular, the light guide layer 4 has a light guide portion 4x formed in a portion facing the transparent base material 2 and in a portion where the background coating portion 3a is not formed. Since the light guide layer 4 has the light guide portion 4x and is formed so as to cover the background coating portion 3a from the surface side, it is suitable for painting the surface layer 5 above the uneven portion by the background coating portion 3a. A smooth surface will be formed.
Similar to the top clear portion 5c described later, the material of the light guide layer 4 may be a UV paint whose coating film is cured by irradiating with ultraviolet rays instead of a polyester-based paint. In this way, by irradiating ultraviolet rays with the UV paint, the drying time can be reduced and thick coating can be performed. Therefore, the number of intermediate coatings of the light guide layer 4 can be reduced to reduce the manufacturing man-hours. Further, since the UV coating material can shorten the drying time by irradiating it with ultraviolet rays, it is possible to suppress the occurrence of unevenness in the thickness of the light guide layer 4 or the top clear portion 5c, and it is possible to form these thinly.

The surface layer 5 includes a light-shielding / reflective layer 5a adhered to the surface side of the light guide layer 4, a lacquer portion 5b formed on the surface side of the light-shielding / reflective layer 5a, and a light-shielding / reflective layer 5a and a lacquer portion 5b. It is composed of a top clear portion 5c coated so as to cover it. Here, the light-shielding / reflective layer 5a and the lacquer work portion 5b are portions corresponding to the second decorative portion according to the present invention.

The light-shielding / reflective layer 5a is a painted portion coated with white urethane coating or the like having light-shielding property and light-reflecting property, and among the light emitted to the surface side of the decoration product 1 through the light guide section 4x. This is for blocking and reflecting the light passing through the lacquer portion 5b. The light-shielding / reflective layer 5a has a light-shielding property, and by blocking light toward the lacquer work portion 5b, it is possible to increase the contrast with respect to the light passing through the emission part 5x described later around the lacquer work part 5b. It is possible to make 5b stand out.
Further, the light-shielding / reflective layer 5a has light reflectivity, and by reflecting light toward the lacquer portion 5b, the amount of light passing through the emission portion 5x described later around the lacquer portion 5b can be increased. It is possible to make the lacquer work part 5b stand out.

The light-shielding / reflective layer 5a is formed so as to cover the light guide portion 4x of the light guide layer 4 from the surface side which is the exposed surface side of the surface layer 5 which is not the transparent base material 2 side. Strictly speaking, the light-shielding / reflective layer 5a is formed so as to protrude outside the boundary 10 in the direction perpendicular to the front and back directions of the background coating portion 3a and the light guide portion 4x. In other words, the boundary 10 between the background coating portion 3a and the light guide portion 4x is located inside the outer periphery of the light-shielding / reflective layer 5a (lacquer portion 5b), so that the light-shielding / reflective layer 5a is located in the front-back direction of the decoration product 1. It is formed at a position that overlaps with.

In the present embodiment, the lacquer portion 5b forms a decoration for a goldfish, and is a portion coated on the light-shielding / reflective layer 5a, for example, a natural lacquer portion is lacquered with gold leaf or the like. , Has a film thickness of about 1 mm or less.
The top clear portion 5c is made of a translucent resin material containing, for example, a UV paint. The top clear portion 5c covers and protects surfaces other than the peripheral surface of the light-shielding / reflective layer 5a and the bottom surface of the lacquer portion 5b, and smoothes the surface. The portion of the top clear portion 5c that does not intersect the light-shielding / reflective layer 5a and the lacquer portion 5b in the front-back direction functions as a emission portion 5x that emits light passing through the light guide portion 4x to the surface side.

The present invention relates to the present invention for shining light on a portion of the decorative item 1 facing the back surface of the transparent base material 2 so that the lacquer portion 5b emerges from the background coating portion 3a via the transparent base material 2 or the like. A plurality of LEDs 8 as a light source are attached. The LED 8 according to the present embodiment is a member arranged in a layer shape extending in parallel with the transparent base material 2.
In FIG. 2, a space is formed between the transparent base material 2 and the LED 8. Whether to form this space or not to form a space by directly contacting the transparent base material 2 and the LED 8 can be arbitrarily changed according to the mounting method of the transparent base material 2 and the LED 8 in the decorative item 1. Can be done.

Further, the light source may be any member as long as it is a member that emits light, and is not limited to the LEDs 8 arranged in layers. The light source is, for example, a light source that is located at a position facing the transparent base material 2 and is not formed in a layer shape extending in parallel with the transparent base material 2, but emits light from an arbitrary position as a reflective material such as a mirror. The transparent base material 2 may be irradiated via a light guide member made of a light-transmitting material and a light-transmitting material. Further, the present invention is not limited to LEDs, and may be light bulbs, liquid crystals, LDs (Laser Diodes), organic EL (Organic Electro Luminescence) elements, and other solid-state light emitting elements.

Then, while supplying electric power to the LED 8, a control unit C for turning on / off the light emission of the LED 8 and selectively enabling only a part of the LED 8 to emit light, which will be described in detail later, is connected to the LED 8. Has been done.

(About the decoration effect of decorations)
Under the control of the control unit C, the light emitted from the LED 8 passes through the transparent base material 2, the light guide unit 4x to the light guide layer 4, and the gap between the background coating portion 3a and the light-shielding / reflection layer 5a. It is discharged from the discharging portion 5x to the surface side of the decoration product 1 through the discharging portion 5. As shown in FIG. 3, the light emitted from the emission portion 5x brightens the surroundings so as to make the lacquer portion 5b stand out.

In particular, as described above, the boundary 10 between the background coating portion 3a and the light guide portion 4x is formed inside the outer periphery of the light-shielding / reflective layer 5a (lacquer portion 5b). Therefore, even when the light is not emitted from the LED 8, the gap between the background coating portion 3a and the lacquer portion 5b (light-shielding / reflection layer 5a) (in other words, the background coating portion 3a and the light guide portion 4x) The boundary 10) can be made difficult to see from the surface side, and the appearance can be improved. Further, when the light is emitted from the LED 8, it is possible to suppress the direct light incident on the eyes of the user and impart a high design effect as indirect lighting.

Further, when the thickness of the background coating portion 3a and the lacquer portion 5b has a predetermined relationship, even if the emission portion 5x and the LED 8 are not linearly communicated with each other, the background coating is performed due to the light diffraction effect. Light can be emitted to the emitting portion 5x from between the portion 3a and the lacquer portion 5b (light-shielding / reflective layer 5a). That is, when the user looks at the surface of the surface layer 5 of the decorative item 1 from an angle, the gap between the background coating portion 3a and the lacquer painting portion 5b (light-shielding / reflective layer 5a) cannot be seen at all. Even with the configuration, light can be emitted from the emission unit 5x.

(About the manufacturing method of decorative products)
As a method for manufacturing the above-mentioned decorative item 1, first, a transparent base material 2 is prepared. The background coating portion 3a is applied to the surface side of the prepared transparent base material 2. At this time, the background coating portion 3a is applied to the transparent base material 2 with the portion to be the light guide portion 4x masked.
Then, the light guide layer 4 is applied to the surface side of the background coating portion 3a to form the light guide layer 4, and the light shielding / reflection layer 5a and the lacquer work portion 5b are applied to the surface side of the light guide layer 4.
At this time, the light-shielding / reflective layer 5a and the lacquer portion 5b are sequentially applied to the light guide layer 4 with the portion to be the emission portion 5x masked, and further, the light guide layer 4 and the lacquer portion 5b are covered from the surface side. The top clear portion 5c is applied to form the surface layer 5. When the light-shielding / reflective layer 5a and the lacquer portion 5b are applied to the light guide layer 4, they are overlapped with at least a part of the boundary 10 between the background coating portion 3a and the light guide portion 4x in the front and back directions. ..
In this way, the decorative item 1 capable of emitting light from a part around the lacquer work portion 5b can be manufactured.

<First modification>
Next, the decorative item 1a according to the first modification will be described with reference to FIGS. 4 to 6. 4A and 4B are views showing the surface of the decorative item 1a according to the first modification, and FIG. 4 is a plan view showing a state in which light is not irradiated, and FIG. 5 is a sectional view showing a VV cross section of FIG. FIG. 6 is a view corresponding to FIG. 4, and is a plan view showing a state in which light is irradiated.

One of the differences between the decorative product 1a and the decorative product 1 is that the decorative product 1a has a light-shielding / reflective layer 5a in the surface layer 15 as shown in FIG. 5, unlike the decorative product 1 according to the above embodiment. Not prepared.
In the decorative item 1 according to the above embodiment, the configuration in which the light-shielding / reflective layer 5a is provided on the back surface of the lacquer work portion 5b has been described. Since the light-shielding / reflective layer 5a has a light-shielding property, it is possible to suppress the emission of light from the lacquer portion 5b to the surface side, and the contrast between the light and darkness with the emitted light 9 emitted from the emission portion 5x is enhanced. Therefore, the design effect of the decorative item 1 can be enhanced. Further, since the light-shielding / reflective layer 5a has light reflectivity, the amount of light emitted from the emitted portion 5x can be increased.
However, in order to obtain the effect of making the lacquer portion 5b stand out, it is sufficient that the lacquer portion 5b has a lower translucency than the translucency of the top clear portion 5c constituting the emission portion 5x according to the above embodiment. Further, if sufficient light is emitted from the emission unit 5x, the light-shielding / reflective layer 5a having light reflectivity has an arbitrary configuration.

Further, in the decorative product 1a, unlike the decorative product 1 according to the above embodiment, the top clear portion 5c is not formed in the surface layer 15. It is desirable to provide the top clear portion 5c on the surface side of the decorative product 1 according to the above embodiment because the lacquer portion 5b can be protected and the surface of the decorative product 1 can be smoothed.
However, when the importance of smoothing the surface side of the decorative item 1 is low and the need for protection of the lacquer portion 5b is low, for example, by providing a cover member (not shown) on the surface side, the decorative item 1a is used. As described above, the top clear portion 5c may not be provided. As described above, in the case of the decorative item 1a not provided with the top clear portion 5c, the man-hours for applying the top clear portion 5c to the light guide layer 4 can be reduced, and the space around the lacquer portion 5b as a discharge portion can be reduced. Since the light can be emitted directly, the design effect can be enhanced.

Further, the background coating portion 3b applied on the transparent base material 2 according to the decoration product 1a is different from the background coating portion 3a of the decoration product 1 according to the above embodiment. Specifically, the boundary 10a in the direction perpendicular to the front and back directions between the background coating portion 3b and the light guide portion 4x on the left side in FIG. 5 is outside so as to form a gap G between the lacquer portion 5b in the surface direction. It is in.

By forming the background coating portion 3b in this way, the light emitted from the LED 8 can be linearly emitted only partially through the gap G between the background coating portion 3b and the lacquer portion 5b. Therefore, as shown in FIG. 6, the amount of light emitted from only a part of the emitted light 9a on the surface side of the gap G can be increased, and the design effect can be enhanced.

Further, the boundary 10b of the background coating portion 3c and the light guide portion 4x on the right side in FIG. 5 in the direction perpendicular to the front and back directions is at a position corresponding to the outer periphery of the lacquer portion 5b in the front and back directions. Even in such a positional relationship, the lacquer portion 5b limits at least a part of the linear emission of the light emitted from the LED 8. Therefore, even in such a case, the decorative item 1a can obtain a design effect as indirect lighting.

That is, if the lacquer portion 5b is formed at a position where it overlaps at least a part of the light guide portion 4x in the front-back direction, the amount of light emitted from the LED 8 and the location where the light is emitted can be limited. Further, a part of the lacquer portion 5b is formed at a position where it overlaps at least a part of the boundary 10b between the background coating portion 3c and the light guide portion 4x in the front-back direction, thereby exhibiting a design effect as indirect lighting. be able to.
In other words, the decorative article according to the present invention only needs to be able to exert a design effect as indirect lighting in at least a part thereof, and the boundary 10 is formed inside in the plane direction over the entire circumference of the lacquer work portion 5b. You don't have to be.

(About light production)
Next, with reference to FIG. 7, the light effect of the decorative item 1 will be described. Regarding the light effect described below, the same effect can be achieved with the decorative item 1a. Here, FIG. 7 is a plan view showing the light effect of the decorative item 1.
The decorative item 1 is designed by simply irradiating the periphery of the lacquer work portion 5b to make the lacquer work part 5b appear to stand out from the background painting part 3a, and also to produce various light effects under the control of the control unit C. The effect may be enhanced.

For example, the control unit C controls so that the emission and emission of the light by the LED 8 are gradually repeated at predetermined intervals, so that the emitted light 9 shown in FIG. 3 is extinguished and turned on like the light of a firefly. You may do it. Further, as shown in FIG. 7, the control unit C emits light only from a part of the plurality of arranged LEDs 8 so as to sequentially turn on the emitted light 9b at a plurality of locally scattered locations. It may be controlled to. Further, in the control unit C, among the plurality of arranged LEDs 8, the adjacent LEDs 8 are sequentially turned on and off, and the emitted light 9b is continuously moving so as to connect the plurality of locally scattered locations. It is also possible to make it look like.
It should be noted that the decorative item 1 does not require the above-mentioned effect, and does not need to include the control unit C when only the on / off of the light emission is operated.

<Second modification>
Next, the decorative item 1e according to the second modification will be described with reference to FIG. Here, FIG. 8 is a view showing the surface of the decorative item 1e according to the second modification, and is a plan view showing a state in which light is not irradiated.
In the decorative items 1 and 1a according to the above embodiment, an example in which at least a part of the lacquer work portion 5b is formed at a position overlapping with at least a part of the boundaries 10 and 10b in the front and back directions has been described. With such a configuration, at least a part of the lacquer work portion 5b can be indirectly illuminated by the emitted light 9, so that the design effect can be enhanced. However, the invention of the present application is not limited to such a form.

The decorative item 1e according to the second modification is, for example, about 1 mm to 5 mm between the boundary perpendicular to the front and back directions of the background coating portion 3b and the light guide portion 4x and the edge in the surface direction of the lacquer portion 5b. It is configured so that the gap G1 is formed. The gap G1 has a gap G between the lacquer portion 5b and the background coating portion 3b described with reference to FIGS. 4 and 5 in the first modification with respect to the edge of the lacquer portion 5b over the entire circumference in the surface direction. It is formed.
In this way, even if the gap G1 is formed in the decorative item 1e, the lacquer portion 5b is formed in the vicinity of the boundary perpendicular to the front and back directions between the background coating portion 3b and the light guide portion 4x, so that the lacquer portion is formed. It is possible to obtain a visual effect (design effect) in which 5b appears to appear three-dimensionally with respect to the background coating portion 3b.

The method for manufacturing the decorative item 1e is the same as the method for manufacturing the decorative item 1. The specific difference is that when the light-shielding / reflective layer 5a and the lacquer portion 5b are applied to the light guide layer 4, they are located near the inside in the surface direction of the boundary between the background coating portion 3a and the light guide portion 4x. It is a point to apply so that it is located.

In the above embodiment, it has been described that the second decorative portion painted so as to cover the light guide portion 4x from the surface side is the lacquer portion 5b. When the second decorative portion is the lacquer portion 5b in this way, the three-dimensional decoration reflects the light emitted from the surroundings to the lacquer portion 5b, so that the shadow of the lacquer portion 5b can be emphasized. High design effect.
However, the second decorative portion is not limited to the one that has been lacquered and may be coated with a colored paint. For example, assuming that the second decorative portion is a portion to which a paint of the same color as the background coating portion 3a is applied, no pattern is identified in the state where the light is not emitted from the LED 8, and the light is emitted from the LED 8. For the first time, the second decorative part may be made to emerge.

Further, in the decorative item 1, the light-shielding / reflective layer 5a is provided on the back surface of the lacquer work portion 5b, but the light-shielding / reflective layer 5a may be provided on the back surface of the background coating portion 3a. By doing so, the light transmitted from the background coating portion 3a can be suppressed, and the contrast between the emitted light 9 and the background coating portion 3a can be emphasized. Therefore, the emitted light 9 can make the lacquer work portion 5b appear to stand out more, and the design effect of the decorative item 1 can be enhanced.

The decorative item according to the present invention can be used indoors or outdoors, such as a lantern, a shade of a lighting fixture, a switch panel of a vehicle, a foot light, a garnish, etc., and when used in a dark place, light from a light source is used. The production of is effective.
