Description

この発明は、オーナメントなどの発光装飾体に関するものである。   The present invention relates to a light-emitting decorative body such as an ornament.

車両には、エンブレムやネームプレート等のオーナメントが設けられ、オーナメント自体を発光させることで、装飾性を高めている(例えば特許文献１参照)。特許文献１に開示のオーナメントは、日中などにおいては、カバーに設けた金属性薄層によって光を反射して輝き、夜間などの暗いときには、内部に配設された光源から光を照射することで、金属性薄層の孔を介して光源の色彩が反映されるようになっている。   The vehicle is provided with ornaments such as emblems and nameplates, and the ornament is enhanced by causing the ornaments to emit light (see, for example, Patent Document 1). The ornament disclosed in Patent Document 1 shines by reflecting light by a metallic thin layer provided on the cover during the daytime, and illuminates light from the light source disposed inside when it is dark at night or the like. Thus, the color of the light source is reflected through the holes in the thin metallic layer.

特開２００７−１６１２３３号公報JP 2007-161233 A

前記オーナメントは、光源によって照らされる部分周辺が明るくなる一方、光源と光源との間が暗くなり、光源の配置によって明るさにむらができてしまう。このような明るさのむらを解消するために、光源を密に配置することが考えられるが、光源を多く必要とするために部品点数や消費電力の増加を招く難点が指摘される。また、オーナメントは、全体的なデザインや周囲とのバランスなどの制約によって、ベースとカバーとの間隔を大きくとることができず、このため光源から照射された光が十分に拡散しないまま金属性薄層に投影されて、明るさのむらが更に大きくなってしまう。   In the ornament, the periphery of the portion illuminated by the light source becomes brighter, while the space between the light sources becomes darker, resulting in uneven brightness depending on the arrangement of the light sources. In order to eliminate such uneven brightness, it is conceivable to arrange the light sources densely. However, since a large number of light sources are required, it is pointed out that the number of components and power consumption increase. In addition, the ornament cannot make the gap between the base and the cover large due to constraints such as the overall design and balance with the surroundings. Projected on the layer, the uneven brightness is further increased.

すなわち本発明は、従来の技術に係る発光装飾体に内在する前記問題に鑑み、これらを好適に解決するべく提案されたものであって、少ない光源でむらなく発光装飾し得る発光装飾体を提供することを目的とする。   That is, the present invention has been proposed to solve these problems inherently in the light-emitting decorative body according to the prior art, and provides a light-emitting decorative body that can be uniformly decorated with a small number of light sources. The purpose is to do.

前記課題を克服し、所期の目的を達成するため、本願の請求項１に係る発明の発光装飾体は、
基板の一面に実装された光源と、
前記光源の光照射方向前側に配設され、該光源から照射された光を反射する反射部と、
前記光源を挟んで前記反射部と反対側に配設され、該反射部の反射光を拡散して透過する拡散体と、
前記拡散体を透過した前記反射光が入射可能な位置に配設され、入射する光の一部を反射すると共に該光の一部を透過するハーフミラー部および該ハーフミラー部における前記反射部側の内側に重ねて配設され、光を拡散して透過可能な散乱部を有する装飾部とを備え、
前記光源が実装された前記基板と前記拡散体とは上下に重なるように配設されて、前記装飾部と前記反射部との間に配設されており、
前記光源の大きさよりも前記基板の方が大きくなっており、
前記光源から照射した光は前記ハーフミラー部に直接入射させるのではなく、前記反射部で反射させて拡散すると共に、前記拡散体および前記散乱部で拡散した後に、前記ハーフミラー部に入射させるよう構成したことを要旨とする。
請求項１に係る発明によれば、光源から照射した光を反射部での反射および拡散体により拡散させた後にハーフミラー部に入射させるから、光源の位置だけが明るくなることを回避でき、ハーフミラー部をむらなく一様に光らせることができる。また、装飾部に設けた散乱部によって光を拡散することで、光源の発光時に、発光装飾体の内部構造の影を視認し難くすることができる。更に、光源を実装した基板が拡散体に対する反射光の入射の邪魔にならない。 In order to overcome the above-mentioned problems and achieve the intended object, the light-emitting decorative body of the invention according to claim 1 of the present application,

According to the first aspect of the invention, since the light emitted from the light source is reflected by the reflecting portion and diffused by the diffuser and then incident on the half mirror portion, it can be avoided that only the position of the light source becomes bright, and half The mirror part can be illuminated uniformly. Moreover, by diffusing light with the scattering part provided in the decoration part, it is possible to make it difficult to visually recognize the shadow of the internal structure of the light-emitting decoration body when the light source emits light. Furthermore, the substrate on which the light source is mounted does not interfere with the incidence of reflected light on the diffuser.

請求項２に係る発明では、前記反射部は、独立気泡構造の発泡体シートによって構成されたことを要旨とする。
請求項２に係る発明によれば、発泡体シートからなる反射部は、光反射の角度依存性が少ないので、ハーフミラー部をよりむらなく光らせることができる。 The gist of the invention according to claim 2 is that the reflecting portion is formed of a foam sheet having a closed cell structure.
According to the invention which concerns on Claim 2 , since the reflection part which consists of foam sheets has little angle dependency of light reflection, it can make a half mirror part shine more uniformly.

前記複数の光源１６は、基板１８の一面(下面)に実装されており、これらの光源１６から同じ向き(実施例では下方)に光を照射し得るよう構成される(図２参照)。基板１８は、ベース部１２と装飾部１４との間に画成された設置空間１０ａにおいて、ベース部１２および装飾部１４の両方から離間した上下方向の中間部に配置され(図２参照)、設置空間１０ａの幅(光照射方向と交差する方向の寸法)よりも狭小に形成される(図１参照)。ここで、基板１８は、発光装飾体１０の平面形状に合わせてリング形状に形成され、基板１８における内外の周縁と設置空間１０ａを画成する内外の壁面との間に、光が通過する隙間があいている。また、基板１８には、複数の光源１６が同じ間隔になるように並べられ、円形配列された複数の光源１６が、設置空間１０ａを画成する内外の壁面間の中央部に配置される(図１参照)。光源１６としては、ＬＥＤや電球などを採用可能であり、実施例ではＬＥＤが用いられている。なお、基板１８を、白色にする等によって光を反射可能に構成し、反射部２０と基板１８との間で光源１６から照射した光の乱反射を図ってもよい。   The plurality of light sources 16 are mounted on one surface (lower surface) of the substrate 18 and are configured to be able to emit light from these light sources 16 in the same direction (downward in the embodiment) (see FIG. 2). The substrate 18 is disposed in an intermediate portion in the vertical direction separated from both the base portion 12 and the decorative portion 14 in the installation space 10a defined between the base portion 12 and the decorative portion 14 (see FIG. 2). It is formed narrower than the width of the installation space 10a (dimension in the direction crossing the light irradiation direction) (see FIG. 1). Here, the board | substrate 18 is formed in ring shape according to the planar shape of the light emission decoration body 10, and the clearance gap which light passes between the inner and outer periphery in the board | substrate 18, and the inner and outer wall surface which defines the installation space 10a.

Inside the base portion 12, a reflection portion 20 capable of reflecting light is provided. In the embodiment, not only the bottom wall 12a of the base portion 12 positioned on the front side in the light irradiation direction of the light source 16, but also the outer periphery and the inner periphery. The reflection part 20 is arrange | positioned over the vertical walls 12b and 12b. The reflecting portion 20 can be adopted as long as it can reflect light, such as a foam sheet having light reflectivity, a coating film made of a reflective paint, and a metallic coating such as plating. It is preferable to use a body sheet. The foam sheet (for example, FOLEC manufactured by Inoac Corporation, Inc.) that forms the reflective portion 20 of the example is a polyolefin-based (particularly PP (polypropylene)) foam having a closed cell structure obtained by a supercritical method in a sheet form. It is formed and has fine bubbles independent of each other.

前記拡散体２２は、前記設置空間１０ａにおいて、ベース部１２および装飾部１４の両方から離間した上下方向の中間部に配置される(図２参照)。また、拡散体２２は、光源１６を挟んで反射部２０と反対側に位置して、反射部２０と対面するように配設されており、光源１６から照射された光を直接受けないようになっている。拡散体２２は、発光装飾体１０の平面形状に合わせてリング形状に形成され、その幅が設置空間１０ａの幅と同一寸法で形成されている。すなわち、拡散体２２は、設置空間１０ａにおける光源１６の上方を塞ぐように配設され、基板１８と設置空間１０ａを画成する壁面との隙間に臨み、反射部２０で反射した反射光が入射するようになっている。なお、実施例では、拡散体２２の下面に基板１８が設置される。そして、発光装飾体１０では、基板１８と拡散体２２とが上下に重なるように配設されるが、基板１８が拡散体２２より幅狭に形成される。ここで、拡散体２２は、アクリル、ポリカーボネートやＡＢＳ等の合成樹脂またはガラスなどの、透明または半透明の板状部材であり、入射した光を透過可能に構成される。また、拡散体２２は、表面にシボ加工などにより凹凸を設けたり、透明素材中に炭酸カルシウムや酸化チタンなどの光を反射し得る反射性微粒子を散在させたりすること等により、入射した光を拡散するように構成される。具体的には、拡散体２２として、すりガラスや乳白色アクリルなどを用いることができる。   The diffuser 22 is disposed in an intermediate portion in the vertical direction spaced apart from both the base portion 12 and the decorative portion 14 in the installation space 10a (see FIG. 2). Further, the diffuser 22 is located on the opposite side of the reflection unit 20 with the light source 16 in between so as to face the reflection unit 20 so as not to directly receive the light emitted from the light source 16. It has become. The diffuser 22 is formed in a ring shape in accordance with the planar shape of the light emitting decorative body 10, and the width thereof is formed with the same dimension as the width of the installation space 10a. That is, the diffuser 22 is disposed so as to close the light source 16 in the installation space 10a, faces the gap between the substrate 18 and the wall surface that defines the installation space 10a, and the reflected light reflected by the reflection unit 20 enters. It is supposed to be. In the embodiment, the substrate 18 is installed on the lower surface of the diffuser 22. In the light emitting decorative body 10, the substrate 18 and the diffuser 22 are disposed so as to overlap each other, but the substrate 18 is formed to be narrower than the diffuser 22. Here, the diffuser 22 is a transparent or translucent plate-like member such as a synthetic resin such as acrylic, polycarbonate, ABS, or glass, and is configured to transmit incident light. In addition, the diffuser 22 is configured to irradiate incident light by providing irregularities on the surface by embossing or the like, or by scattering reflective fine particles such as calcium carbonate and titanium oxide in a transparent material. Configured to diffuse. Specifically, frosted glass, milky white acrylic, or the like can be used as the diffuser 22.

前記装飾部１４は、平面視でリング形状に形成されると共に、半径方向に破断した断面視で下方に開口する箱状に形成され、外周側の下縁および内周側の下縁を、ベース部１２における縦壁１２ｂの上縁に突き合わせて組み付けられる(図２参照)。装飾部１４は、拡散体２２を透過した反射光が入射可能な位置に設けられ、入射する光の一部を反射すると共に該光の一部を透過するハーフミラー部２４と、このハーフミラー部２４に重ねて設けられ、光を拡散して透過可能な散乱部２６とを有している。装飾部１４は、光源１６を挟んで反射部２０と反対側で、かつ拡散体２２に対して反射部２０から遠ざかる側(上側)に離間して配設される。装飾部１４は、反射部２０側の内面に散乱部２６が設けられると共に、散乱部２６よりも外側にハーフミラー部２４が設けられる。ハーフミラー部２４は、装飾部１４の全面または一部に設けることができ、ハーフミラー部２４によって装飾部１４の意匠面に臨む金属調の模様や文字などを形成したり、実施例のように装飾部１４の全面に設けることで、装飾部１４全体を金属調にすることができる。実施例の装飾部１４は、アクリル、ポリカーボネートやＡＢＳ等の合成樹脂またはガラスなどの、透明または半透明の板状部材である散乱部２６の外面に、ハーフミラー部２４が層状に形成される。ハーフミラー部２４は、装飾部１４を構成する基材(実施例では散乱部２６)に、アルミ等の金属を不連続蒸着したり、該基材の表面に、不連続蒸着フィルムを貼り付けたりすることなどにより形成される。装飾部１４は、不透明なハーフミラー部２４により外方から内部を視認できないようになっている。散乱部２６は、表面にシボ加工などにより凹凸を設けたり、透明素材中に炭酸カルシウムや酸化チタンなどの光を反射し得る反射性微粒子を散在させたりすること等により、拡散体２２と同様に、入射した光を拡散するように構成される。具体的には、散乱部２６として、すりガラスや乳白色アクリルなどを用いることができる。   The decorative portion 14 is formed in a ring shape in a plan view and is formed in a box shape that opens downward in a cross-sectional view broken in the radial direction, and has a lower edge on the outer peripheral side and a lower edge on the inner peripheral side as a base. The part 12 is assembled to the upper edge of the vertical wall 12b (see FIG. 2). The decoration unit 14 is provided at a position where the reflected light transmitted through the diffuser 22 can enter, and a half mirror unit 24 that reflects a part of the incident light and transmits a part of the light, and the half mirror unit 24 and a scattering portion 26 that is provided so as to be able to diffuse and transmit light. The decorative portion 14 is disposed on the side opposite to the reflecting portion 20 with the light source 16 in between and on the side away from the reflecting portion 20 (upper side) with respect to the diffuser 22. The decoration part 14 is provided with a scattering part 26 on the inner surface on the reflection part 20 side and with a half mirror part 24 on the outer side of the scattering part 26. The half mirror part 24 can be provided on the entire surface or a part of the decorative part 14, and the half mirror part 24 forms a metallic pattern or characters facing the design surface of the decorative part 14, or as in the embodiment. By providing it on the entire surface of the decorative portion 14, the entire decorative portion 14 can be made metallic. In the decorative portion 14 of the embodiment, a half mirror portion 24 is formed in a layer on the outer surface of a scattering portion 26 that is a transparent or translucent plate-like member such as a synthetic resin such as acrylic, polycarbonate, ABS, or glass. The half mirror unit 24 discontinuously vapor-deposits a metal such as aluminum on the base material (scattering unit 26 in the embodiment) constituting the decoration unit 14, or attaches a discontinuous vapor deposition film to the surface of the base material. It is formed by doing. The interior of the decorative portion 14 cannot be visually recognized from the outside by the opaque half mirror portion 24. The scatterer 26 is similar to the diffuser 22 by providing irregularities on the surface by embossing or the like, or by scattering reflective fine particles that can reflect light such as calcium carbonate and titanium oxide in the transparent material. , Configured to diffuse incident light. Specifically, frosted glass, milky white acrylic, or the like can be used as the scattering portion 26.

〔実施例の作用〕
次に、実施例に係る発光装飾体１０の作用について説明する。発光装飾体１０は、日中などの明るいときには、日光などの外側から入射する光をハーフミラー部２４で反射して、金属のような質感で輝く。このとき、発光装飾体１０は、不透明なハーフミラー部２４によって内部を見通すことができない。発光装飾体１０は、光源１６を点灯することで、複数の光源１６から照射されて反射部２０で反射された反射光が、拡散体２２に入射して拡散され、拡散体２２で拡散された光が装飾部１４の散乱部２６に入射して拡散され、この拡散光によってハーフミラー部２４(装飾部１４の表面)がぼんやりと光るように発光装飾される。このように、発光装飾体１０は、複数の光源１６から照射した光を発光させたい部分であるハーフミラー部２４に直接入射させるのではなく、反射部２０による反射により拡散すると共に拡散体２２および散乱部２６で更に拡散した後に、ハーフミラー部２４に入射させるから、光源１６の位置だけが明るくなることを回避できる。従って、光源１６を増やすことなく、発光装飾体１０の意匠面をむらなく一様に光らせることができる。そして、光源１６の数を減らすことができるから、部品点数を減らしてコストダウンし得ると共に省電力になり、また光源１６の発熱による不都合が起き難い。ここで、光源１６を実装した基板１８は、拡散体２２およびハーフミラー部２４と重なる関係にあるが、拡散体２２およびハーフミラー部２４よりも基板１８が幅狭に形成されているので、基板１８が拡散体２２およびハーフミラー部２４に対する光の入射の邪魔にならない。 (Effects of Example)
Next, the operation of the light emitting decorative body 10 according to the embodiment will be described. When the light-emitting decorative body 10 is bright, such as during the daytime, light that is incident from the outside, such as sunlight, is reflected by the half mirror unit 24 and shines with a metal-like texture. At this time, the interior of the light emitting decorative body 10 cannot be seen through the opaque half mirror portion 24. The light-emitting decorative body 10 turns on the light source 16 so that the reflected light irradiated from the plurality of light sources 16 and reflected by the reflecting unit 20 enters the diffuser 22 and is diffused and diffused by the diffuser 22. Light is incident on the scattering portion 26 of the decorative portion 14 and diffused, and the diffused light is decorated so that the half mirror portion 24 (the surface of the decorative portion 14) shines softly. As described above, the light emitting decorative body 10 does not directly enter the half mirror part 24 which is a part where light emitted from the plurality of light sources 16 is desired to be emitted, but diffuses by reflection by the reflecting part 20 and diffuses and Since the light is further diffused by the scattering unit 26 and then incident on the half mirror unit 24, it is possible to avoid that only the position of the light source 16 becomes bright. Therefore, the design surface of the light emitting decorative body 10 can be uniformly illuminated without increasing the number of light sources 16. Since the number of light sources 16 can be reduced, the number of parts can be reduced to reduce the cost and power can be saved, and inconvenience due to heat generation of the light sources 16 hardly occurs. Here, the substrate 18 on which the light source 16 is mounted overlaps with the diffuser 22 and the half mirror part 24, but the substrate 18 is formed narrower than the diffuser 22 and the half mirror part 24. 18 does not interfere with the incidence of light on the diffuser 22 and the half mirror section 24.

前記発光装飾体１０は、光源１６を挟んで反射部２０と反対側にハーフミラー部２４を配設しているので、光源１６から照射された光が反射部２０で反射してハーフミラー部２４に入射するまでの距離をかせぐことができ、光源１６とハーフミラー部２４とを近接配置することができる。特に、収束性のよい光を照射し得るＬＥＤを光源１６として用いた場合であっても、前述のように、光源１６とハーフミラー部２４との距離を確保することができるので、光源１６の位置だけが明るくなることを回避して、ハーフミラー部２４をむらなく発光させることができる。従って、発光装飾体１０は、ベース部１２、基板１８、拡散体２２および装飾部１４の重なり方向にコンパクトにでき、これにより全体的なデザインの自由度も向上する。また、拡散体２２で反射光を拡散することで、基板１８等の発光装飾体１０の内部構造の影を外部から視認し難くすることができる。実施例では、装飾部１４に設けた散乱部２６によっても更に光を拡散しているので、光源１６の発光時に、発光装飾体１０の内部構造の影をより視認し難くすることができる。   Since the light-emitting decorative body 10 has the half mirror part 24 disposed on the opposite side of the reflection part 20 with the light source 16 in between, the light irradiated from the light source 16 is reflected by the reflection part 20 and the half mirror part 24. The light source 16 and the half mirror part 24 can be arranged close to each other. In particular, even when an LED capable of irradiating light with good convergence is used as the light source 16, as described above, the distance between the light source 16 and the half mirror portion 24 can be secured. By avoiding that only the position becomes bright, the half mirror unit 24 can emit light evenly. Therefore, the light-emitting decorative body 10 can be made compact in the overlapping direction of the base portion 12, the substrate 18, the diffuser 22 and the decorative portion 14, thereby improving the degree of freedom in overall design. Further, by diffusing the reflected light with the diffuser 22, it is possible to make it difficult to visually recognize the shadow of the internal structure of the light emitting decorative body 10 such as the substrate 18 from the outside. In the embodiment, since the light is further diffused by the scattering portion 26 provided in the decorative portion 14, it is possible to make the shadow of the internal structure of the light emitting decorative body 10 more difficult to visually recognize when the light source 16 emits light.

前記発光装飾体１０は、反射部２０として前述した発泡体シートを用いることで、反射部２０の反射面に形成されたセルによる微細な凹凸によって、光を反射する際の角度依存性を少なくすることができる。従って、光源１６から照射された光を反射部２０でより適切に拡散することができ、ハーフミラー部２４をよりむらなく光らせることができる。また、拡散体２２を基板１８の設置部分として用いるので、基板１８を設置するために別に設置部を形成する必要はなく、部品点数を減らすことができる。   The light-emitting decorative body 10 uses the above-described foam sheet as the reflection portion 20, thereby reducing the angle dependency when light is reflected by the fine unevenness caused by the cells formed on the reflection surface of the reflection portion 20. be able to. Therefore, the light emitted from the light source 16 can be more appropriately diffused by the reflection unit 20, and the half mirror unit 24 can be emitted more evenly. Further, since the diffuser 22 is used as an installation portion of the substrate 18, it is not necessary to form a separate installation portion for installing the substrate 18, and the number of components can be reduced.
