[Industrial applications]

 The present invention makes it possible to cause a light-emitting portion having a predetermined shape such as a mark to emit light by irradiating it with a light source provided inside, while allowing a light-reflecting portion having a predetermined shape to reflect external light. In particular, the present invention relates to a light emitting ornament (light emitting ornament) that is preferably mounted on an automobile.

[0002]

[Prior Art]

 As a luminous ornament of this kind, a luminous ornament which is attached to a front grill or a rear body of an automobile as a mark has been conventionally known. For example, a light emitting ornament as shown in FIG. 1 can be given as an example. As shown in the figure, this type of luminous ornament is provided on the front cover 10 made of a transparent resin whose surface is uneven according to a desired decorative pattern, and on the back side of the front cover 10 to emit light. LED substrate assembly 14 used as a source. As shown in the figure, the surface of the front cover 10 has a light-shielding layer 18 formed in the portion excluding the convex portions, and therefore, when the LED is made to emit light, only the convex portions, that is, the light emitting portions 20 are formed. Is designed to emit light. In addition, a semi-transparent light reflecting layer 16 formed by metal vapor deposition or the like is laminated on the back surface of the front cover 10, and when external light enters through the light emitting section 20, this light reflecting layer 16 is reflected. The layer 16 provides a metallic reflected light. Further, a light guide 12 made of a translucent resin is provided between the semi-translucent light reflecting layer 16 and the LED substrate assembly 14, and the light emitted from the LED emits light. The guide 12 is used to diffuse the particles uniformly.

When the LED is made to emit light, its irradiation light reaches the light emitting portion 20 of the front cover 10 after passing through the light guide 12 and the semi-transparent light reflecting layer 16. At this time, the irradiation light is refracted or irregularly reflected on the surface of the light emitting portion 20, but as described above, the light emitting portion 20 is composed of a simple convex portion formed on the surface of the front cover 10. Therefore, the refracted / diffusely reflected light is also relatively simple, and the three-dimensional effect of the light emitting unit 20 is poor.

Further, since the semi-transparent light reflecting layer 16 is formed at a position separated from the upper surface or the side surface of the light emitting portion as an incident surface of external light, the light is transmitted through the light emitting portion 20 to enter. When the external light is reflected by the light reflection layer 16, the reflected light becomes indirect reflected light through the front cover 10, so that the reflected light is inevitably a dull light with low brightness. Further, as described above, since the light emitting portion surface 20 as the light refraction / diffuse reflection surface is only the upper surface or the side surface of the simple convex portion formed on the surface of the front cover 10, the light transmitting portion surface 20 outside When the light was reflected by the semi-translucent light reflecting layer 16, the reflected light had to be monotonous.

[0005]

[Problems to be solved by the device]

 Therefore, the technical problem to be solved by the present invention is that when the light emitting portion emits light, the light emitting portion exhibits a more three-dimensional effect, while when external light is incident, the brightness of reflected light is increased. It is an object of the present invention to provide a light-emitting decorative article that has high reflected light and has a superior decorative effect.

[0006]

[Means, actions, and effects for solving problems]

 In order to solve the above problems, the present invention provides a light-emitting ornament having the following configuration. That is, this luminous ornament is a front cover made of a translucent material and having an uneven surface, and a front cover in which further second convex portions are formed on the upper surfaces of the first convex portions, respectively. A semi-transparent light-reflecting metal vapor deposition layer formed on the back surface of the front cover, and a surface light source attached in proximity to the semi-transparent light-reflecting metal vapor deposition layer. A light shielding layer is formed on the entire surface of the concave portion with respect to the first convex portion, and a light reflecting layer is formed on the upper surface of the second convex portion. The light reflecting layer is preferably formed of a metal foil.

According to the above configuration, when the surface light source is caused to emit light at night, the irradiation light passes through the semitransparent light reflecting layer to reach the front cover, and the side surface and the upper surface of the first convex portion, 2 The light passes through the side surface of the convex portion and reaches outside light. Therefore, when the periphery of a pattern such as a mark formed by the light reflecting layer shines, the pattern is three-dimensionally raised in the state of being illuminated from the periphery.

On the other hand, in the daytime, external light is strongly reflected by the light reflecting layer corresponding to the predetermined pattern. Along with this, a part of the external light enters the front cover from the side surface and the upper surface of the first convex portion and the side surface of the second convex portion, and the semi-transparent light reflecting layer formed behind the front cover. It is reflected here and reaches outside again. This reflected light is lower than the brightness of the light reflection layer, and therefore, a three-dimensional design effect is produced in which the light pattern formed by the high brightness light reflection layer is surrounded by the low brightness light pattern.

In the above structure, the metal foil may be semi-translucent. According to this structure, when external light is floated, a part of the external light can be directly reflected by the light reflection layer. Further, when the surface light source is caused to emit light, the irradiation light thereof also passes through the light reflecting layer after passing through the front cover. In other words, this semi-translucent light reflection layer forms a low-luminance light pattern corresponding to a predetermined decorative pattern, and the combination of this low-luminance pattern and the surrounding high-luminance pattern creates a unique design. Can obtain the desired effect.

【Example】

 An embodiment of the present invention will be described in detail below with reference to FIG. FIG. 2 shows a cross-section of a main part of the light emitting ornament according to the present embodiment. As shown in the figure, this light-emitting decorative article includes a front cover 10 formed of a transparent resin layer whose surface is unevenly formed according to a desired decorative pattern, for example, a decorative pattern such as a mark, and the front cover 10. And an LED substrate assembly 14 having a plurality of LEDs, which is fixed to the front cover 10 on the back side thereof. An acrylic resin, for example, is preferably used as the translucent material forming the front cover. Between the LED board assembly 14 and the back surface of the front cover 10, a light guide 12 made of a transparent resin fixed to the front cover 10 is provided so as to uniformly diffuse the light emitted when the LEDs emit light. Is provided. Even if each LED is a point light source, when the light emitted from each point light source passes through the light guide 12, a surface light source can be obtained by the light diffusion action of the light guide 12. The appearance at that time will be good.

On the back surface of the front cover 10, a semi-transparent light-reflecting metal vapor deposition layer 16 is formed, which allows the irradiation light to pass therethrough while the LED emits light. When light is incident, the external light can be reflected. As described above, the surface of the front cover 10 is formed in a concavo-convex shape, and a new second convex portion 26 is formed on each upper surface of the first convex portion 24. As shown in the drawing, a decorative film as the light-shielding layer 18 colored according to the desired decorative pattern is formed on the entire surface of the concave portion with respect to the first convex portion 24. Further, on the entire upper surface of the second convex portion 26, the metal foil 22 as a light reflecting layer is laminated by hot stamping with a hot stamp.

As the metal foil 22, for example, a chrome sheet foil is preferably used. However, when these metal foils are generally to be laminated on a part of the upper surface of the resin layer by hot stamping, a foil breakage is used. It is difficult to form the edge of the metal foil sharply due to the poor quality. However, in the present embodiment, as described above, the second convex portion 26 is further formed on the upper surface of the first convex portion 24 to form a step, and a metal foil is hot stamped on the entire upper surface of the second convex portion 26. As a result, the metal foil is sharply cut at the peripheral edge of the second convex portion 26.
