  The decorative member 301 is a glass, a gem or the like, and the gem is not particularly limited, and examples thereof include quartz, diamond, sapphire, ruby and the like. Further, the decorative member 301 is preferably a glass or a gem cut such as a single cut or a brilliant cut. Glass or gem has light transmission, and cut glass or gem such as single cut or brilliant cut makes light from a certain direction incident and reflects it in a certain direction, and a combination of light and reflection effect You can get the brightness with

  Also, as shown in FIGS. 4 (a) and 4 (b), the cut glass or gem (decorative member) has a crown 401 at the top and a pavilion at the bottom. In other words, the decorative member comprises a crown 401 and a pavilion 402. The crown 401 is an upper part of a gem (or glass), that is, an upper part of a girdle, a polyhedron having a substantially truncated cone shape or a truncated pyramid shape, and is flat at the upper center Table 403 is provided. When single cutting is performed, the crown 401 has eight flat fan-shaped flat surfaces formed around the table 403 and inclined in different directions with respect to the table 403 in addition to the flat table 403. If it has a brilliant cut, the crown 401 forms a quadrangle with a flat table 403 and also with a triangle, eight Star Facets, one side of which is shared with the table 403. It has eight bezel faces (Bezel Facet, also referred to as the main facets of the crown) and a triangle, sixteen Upper Girdle Facets, one side of which is shared with the girdle.

  That is, the crown 401 has a flat table 403 in the upper center and has a substantially truncated cone shape or a truncated pyramid shape. That is, the crown 401 is a polyhedron having a substantially frusto-conical shape or a substantially truncated pyramid shape having a flat table 403 at the upper center.

  As shown in FIGS. 4 (a) and 4 (b), the pavilion 402 is the lower part of the gem (or glass), that is, the lower part of the girdle, and is substantially a truncated cone. It has a shape, a substantially truncated pyramid shape, a substantially conical shape, or a substantially pyramidal shape.

  A light emitting member emits light by being irradiated with excitation light (for example, also called ultraviolet light or ultraviolet light) from a light source unit (for example, ultraviolet light LED) in a partial region of the crown 401 of the decorative member (for example, diamond) When (for example, a fluorescent substance) is disposed, the light-emitting member not only provides brilliance when there is light incident from the outside by effectively utilizing the reflection characteristics of the decorative member, but the light-emitting member emits excitation light Luminosity can be obtained even in a dark place where light does not enter from the outside by utilizing the light emitted by the irradiation and the reflection characteristics of the decorative member.

  The light source unit and the light emitting member (light emitting material) are not particularly limited, and the light emitting member may emit light (visible light) by excitation light emitted from the light source unit.

  In addition, since it is necessary to enhance the decorativeness of the watch dial by arranging a light emitting member (light emitting material) on the decoration member to make the decoration member bright even in a dark place, the light emitting member (light emitting material) It needs to be transparent. The term "transparent" means that visible light can be transmitted, and includes not only colorless and transparent but also colored (colored) transparent.

  Coating, printing, etc. are used as a method of arranging the light emitting member on the decorative member. Hereinafter, a method using application will be described as an example.

  In addition, the reflection characteristics of cut glass and jewelry (for example, the reflection characteristics of Swarovski) have a characteristic that the surface configuration after cutting is set so that light entering from the front is emitted to the front. Therefore, if a fluorescent material is applied to the light incident surface, the light is refracted, which causes unexpected reflection. For example, if a luminescent material is applied to the entire surface of the light incident surface of a cut glass or gem, the reflection characteristics will vary due to the influence of the side sag and the like, and the light will be incident through the luminescent material. , Slightly diminished. Therefore, it is necessary to apply a concentrated phosphor solution of the active light emitting component (lumisis) in a small range as much as possible.

  Hereinafter, the application pattern which applies the light emitting member (light emitting material) in the present invention to a decoration member is explained with reference to Drawing 5 (a)-Drawing 7 (b).

In the drawings, reference numeral 601 denotes an application area of the light emitting member. FIGS. 7 (a) and 7 (b) show a coating pattern for providing a recess on the crown table and applying the region of the recess. That is, it is shown to apply the area of the recess of the table of the crown. In the drawings, reference numeral 701 denotes an application area of the light emitting member.

  Further, in the application pattern shown in FIG. 5 (d) and the application pattern shown in FIG. 6 (d), an example is shown in which each surface constituting the crown is applied at a ratio of 50%. It is merely an example of a predetermined proportion, and is not particularly limited thereto.

  FIGS. 7A and 7B show the case where a brilliant cut is applied, but the application pattern can be applied to the case where a single cut is applied.

  By arranging the light emitting member (light emitting material) on the decorative member, the decorative member can be provided with brilliance and high decorativeness provided by the decorative member even in a dark place where light is not externally applied.

  A flat table at the top center of the crown, as in the application pattern shown in FIG. 5 (a) and the application pattern shown in FIG. In the case where the light emitting member is applied to the area of light, if the light emitting material is applied only to the top surface of the light incident surface of the cut glass or gem (that is, the area of the flat table in the upper center of the crown) Since the coating is applied only to the top surface of the surface, the light emission variation is small, and further, since the range of light incident through the light emitting material is small, the brilliance effect is good. Also, although only concentrated on the top surface (i.e., a flat table at the top center of the crown) and applied, the reflective properties make it appear to be totally shiny.

  In addition, as in the application patterns shown in FIGS. 5 (b), 5 (c), 6 (b) and 6 (c), the light emitting member is formed in the region other than the flat table in the upper center of the crown of the decorative member.

  Also, as in the application pattern shown in FIGS. 5 (d) and 6 (d), the crown is a polyhedron having a flat table at the upper center and having a substantially truncated cone shape or a truncated pyramid shape, In the case where the light emitting member is applied to a predetermined proportion of the area of each surface, the decorativeness provided by the decorative member can be effectively obtained when light enters from the outside, and the decorative member is also obtained when light does not enter from the outside The decorativeness brought about by is effectively obtained.

  Also, as in the application pattern shown in FIG. 6C, the light emitting member is applied to the flat table area in the upper center of the crown of the decorative member and also to a part of the polyhedron constituting the crown. Thus, the decorativeness provided by the decorative member can be effectively obtained when light does not enter from the outside.

  Further, as in the application pattern shown in FIGS. 7A and 7B, when a recess is provided on a flat table at the upper center of the crown of the decorative member and the light emitting member is applied to the region of the recess, Since the groove for the light emitting material is provided, the light emitting material can be stably arranged, and since the light emitting material is included in the reflection characteristic, the brilliance effect is good. Furthermore, since the light emitting member is disposed in the recess, the table of the crown is not raised.

  As mentioned above, although the application | coating pattern of this invention was demonstrated, this is only an example and is not specifically limited. It will be appreciated by those skilled in the art that other application patterns can be used.
