Description

本発明は、光源と、意匠面を有し、光透過性を有する材質でなり、内部を前記光源から出射した光が透過することにより発光する意匠部材とを有する光装飾具に関する。   The present invention relates to a light ornament having a light source and a design member that has a design surface and is made of a light-transmitting material, and emits light when light emitted from the light source passes through the interior.

光装飾具の一例として、図８に示す構成のものがある。図において、導光板１は、４つの端面と、２つの主面とを有する平板状となっている。
この導光板１はハウジング３に配置される。ハウジング３は、上面が開放面３ｂとなり、底部に導光板１が設けられる箱状の本体部３ａと、本体部３ａの開放面を覆うように設けられる蓋部３ｃとからなっている。蓋部３ｃには、本体部３ａの開放面３ｂと対向する穴３ｄが形成されている。 As an example of the light ornament, there is a configuration shown in FIG. In the figure, the light guide plate 1 has a flat plate shape having four end surfaces and two main surfaces.
The light guide plate 1 is disposed in the housing 3. The housing 3 is composed of a box-shaped main body portion 3a in which the upper surface is an open surface 3b and the light guide plate 1 is provided at the bottom, and a lid portion 3c provided so as to cover the open surface of the main body portion 3a. The lid 3c is formed with a hole 3d that faces the open surface 3b of the main body 3a.

ハウジング３の本体部３ａ内には、導光板１の４つの端面のうちの１つの端面に向かって光を照射する光源５が配置されている。
また、ハウジング３の本体部３ａの底面と、導光板１との間には、反射板７が配置されている。この反射板７は導光板１のハウジング３の本体部３ａの底面と対向する主面（２つの主面のうちの一方の主面）から出射した光を再び導光板１内へ反射するものである。 A light source 5 that irradiates light toward one of the four end surfaces of the light guide plate 1 is disposed in the main body 3 a of the housing 3.
A reflecting plate 7 is arranged between the bottom surface of the main body 3 a of the housing 3 and the light guide plate 1. The reflection plate 7 reflects light emitted from the main surface (one main surface of the two main surfaces) facing the bottom surface of the main body 3a of the housing 3 of the light guide plate 1 into the light guide plate 1 again. is there.

導光板１の他方の主面上には、前面板９が配置される。
導光板１のハウジング３の本体部３ａの底面と対向する主面には、乱反射層１１が設けられ、前面板９の２つの主面には、遮光層１３が形成されている。
光源５から出射した光の大部分は、導光板１へ入射し、一部は２つある主面のうちの他方の主面から出射し、前面板９を介して、外部に出射する。 A front plate 9 is disposed on the other main surface of the light guide plate 1.
An irregular reflection layer 11 is provided on the main surface of the light guide plate 1 facing the bottom surface of the main body 3 a of the housing 3, and a light shielding layer 13 is formed on the two main surfaces of the front plate 9.
Most of the light emitted from the light source 5 is incident on the light guide plate 1, and part of the light is emitted from the other main surface of the two main surfaces, and is emitted to the outside through the front plate 9.

導光板１へ入射した光のうち、主面から出射しない残りの光は、導光板１の２つある主面のうちの他方の主面から出射し、反射板７で反射し、再び導光板１内へ入射する（例えば、特許文献１参照）。   Of the light incident on the light guide plate 1, the remaining light not emitted from the main surface is emitted from the other main surface of the two main surfaces of the light guide plate 1, reflected by the reflection plate 7, and again. 1 (for example, refer to Patent Document 1).

しかし、上記構成の光装飾具において、光源の光から出射した光の一部は、導光板１へ入射せず、前面板９に入射したり、ハウジング３の蓋部３ｃの穴３ｄから外部に放射されたりする。
よって、前面板９を見た場合、光っている部分と、光っていない部分との境界が不明瞭であるという問題点がある。 However, in the light ornament having the above-described configuration, a part of the light emitted from the light of the light source does not enter the light guide plate 1 but enters the front plate 9 or passes through the hole 3d of the lid portion 3c of the housing 3 to the outside. It is emitted.
Therefore, when the front plate 9 is viewed, there is a problem that the boundary between the shining part and the non-shining part is unclear.

最初に、図６を用いて、本実施形態の光装飾具の全体構成を説明する。図において、板状の意匠部材５３は、外部に露出する意匠面５３ａを有している。意匠部材５３の意匠面５３ａと対向する面には、２色射出成形法により、第１ベース５５と、第２ベース５７とが形成されている。更に、第１ベース５５と第２ベース５７の間には、長手方向（図６において矢印ｌ方向）に沿って溝５９が形成される。   Initially, the whole structure of the optical ornament of this embodiment is demonstrated using FIG. In the figure, a plate-shaped design member 53 has a design surface 53a exposed to the outside. A first base 55 and a second base 57 are formed on the surface of the design member 53 facing the design surface 53a by a two-color injection molding method. Further, a groove 59 is formed between the first base 55 and the second base 57 along the longitudinal direction (the direction of arrow 1 in FIG. 6).

第１ベース５５、第２ベース５７はいずれも光透過性を有する樹脂材質でなっており、少なくともどちらか一方の部材は、入射した光を意匠部材５３へ導く導光部として機能する。
尚、本実施形態では、第１ベース５５，第２ベース５７は、拡散材（光の散乱現象を応用した添加剤を入れた材料）を含有したアクリル樹脂とした。 Both the first base 55 and the second base 57 are made of a resin material having light transmittance, and at least one of the members functions as a light guide unit that guides incident light to the design member 53.
In the present embodiment, the first base 55 and the second base 57 are made of acrylic resin containing a diffusing material (a material containing an additive applying a light scattering phenomenon).

溝５９には、ＬＥＤ組み立て体（光源組み立て体）６１が超音波溶接法で取り付けられる。
図７を用いて、ＬＥＤ組み立て体６１を説明する。
ＬＥＤ組み立て体６１は、テープ状のＬＥＤ基板６７と、非光透過性材質でなり、ＬＥＤ基板６７を保持するＬＥＤベース６９とからなっている。 An LED assembly (light source assembly) 61 is attached to the groove 59 by an ultrasonic welding method.
The LED assembly 61 will be described with reference to FIG.
The LED assembly 61 includes a tape-shaped LED substrate 67 and an LED base 69 made of a non-light-transmitting material and holding the LED substrate 67.

ＬＥＤ基板７３は、長手方向（図７の矢印ｌ方向）に沿って、複数のＬＥＤ素子（光源）６３と、このＬＥＤ素子６３を駆動する複数の駆動ＩＣ６５とが設けられている。
尚、本実施形態では、ＬＥＤベース６９の材質は、ＡＳＡ樹脂またはポリアセタール樹脂を用いた。 The LED substrate 73 is provided with a plurality of LED elements (light sources) 63 and a plurality of drive ICs 65 for driving the LED elements 63 along the longitudinal direction (the direction of arrow 1 in FIG. 7).
In the present embodiment, the material of the LED base 69 is ASA resin or polyacetal resin.

また、ＬＥＤベース６９は、本体部７１と、本体部７１の意匠部材５３と対向する面上に形成され、ＬＥＤ組み立て体６１を収容する凸部７３とからなっている。
図２−図５、図７に示すように、凸部７３の長手方向（図１、図６、図７において矢印ｌ方向）に沿った２つの側面のうちの一方の側面７３ｓは、導光部として機能する第２ベース５７に当接し、他方の側面７３ｔは第１ベース５５に当接している。凸部７３の長手方向に沿った側面７３ｔには、ＬＥＤ基板６７を収納するスリット７３ｃが形成されている。更に、凸部７３内には、スリット７３ｃに連設され、ＬＥＤ素子６３を収納する光源穴７３ａと、スリット７３ｃに連設され、駆動ＩＣ６５を収納するＩＣ穴７３ｂとが形成されている。 The LED base 69 includes a main body portion 71 and a convex portion 73 that is formed on the surface of the main body portion 71 facing the design member 53 and accommodates the LED assembly 61.
As shown in FIGS. 2 to 5 and 7, one side surface 73 s of two side surfaces along the longitudinal direction of the convex portion 73 (in the direction of arrow l in FIGS. 1, 6, and 7) is a light guide. The other side surface 73 t is in contact with the first base 55. On the side surface 73t along the longitudinal direction of the convex portion 73, a slit 73c for accommodating the LED substrate 67 is formed. Further, a light source hole 73 a that is connected to the slit 73 c and accommodates the LED element 63 and an IC hole 73 b that is connected to the slit 73 c and accommodates the drive IC 65 are formed in the convex portion 73.

また、光源穴７３ａは、凸部７３の一方の側面７３ｓに開口７３ｄを有し、他方の側面７３ｔに開口７３ｆを有している。
そして、光源穴７３ａに収納されるＬＥＤ素子６３は開口７３ｄ、開口７３ｆより奥まった位置に配置される。尚、本実施形態のＬＥＤ素子６１は、側面発光体タイプであり、第２ベース５７と対向する光出射面６３ａより光を出射するようになっている。 The light source hole 73a has an opening 73d on one side surface 73s of the convex portion 73 and an opening 73f on the other side surface 73t.
The LED element 63 accommodated in the light source hole 73a is disposed at a position deeper than the opening 73d and the opening 73f. Note that the LED element 61 of the present embodiment is a side light emitter type, and emits light from a light emitting surface 63 a facing the second base 57.

凸部７３の光源穴７３ａの壁７３ｅのうち、ＬＥＤ素子６１の光出射面６３ａから開口７３ｄまでの壁７３ｅは、ＬＥＤ素子（光源）６１の光出射方向に沿って、ＬＥＤ素子（光源）６１の光出射面６３ａを越えて延びている。よって、凸部７３のＬＥＤ素子６１の光出射面６３ａから開口７３ｄまでの壁７３ｅは、少なくともＬＥＤ素子（光源）６３と、第２ベース（導光部）５７との間の光の経路に沿って配置され、ＬＥＤ素子（光源）６３の光出射面６３ａから出射する光をすべて第２ベース（導光部）５７へ入射させ、ＬＥＤ素子（光源）６３から出射した光が直接意匠部材５３へ入射するのを防止する遮光部として機能する。   Of the wall 73e of the light source hole 73a of the convex portion 73, the wall 73e from the light emitting surface 63a of the LED element 61 to the opening 73d extends along the light emitting direction of the LED element (light source) 61. Extends beyond the light exit surface 63a. Therefore, the wall 73e from the light emitting surface 63a of the LED element 61 of the convex part 73 to the opening 73d is along the light path between at least the LED element (light source) 63 and the second base (light guide part) 57. All the light emitted from the light emitting surface 63a of the LED element (light source) 63 is incident on the second base (light guide part) 57, and the light emitted from the LED element (light source) 63 directly enters the design member 53. It functions as a light-shielding portion that prevents incidence.

尚、本実施形態では、ＬＥＤ素子６１と壁７３ｅとの間に隙間があるので、光出射面６３ａから開口７３ｆまでの壁７３ｅも、ＬＥＤ素子（光源）６３から出射した光が直接意匠部材５３へ入射するのを防止する遮光部として機能する。
上記構成の作動を説明する。図３に示すように、ＬＥＤ素子６３光出射面６３ａから出射した光は、凸部７３の光源穴７３ａの開口７３ｄを介して、凸部７３の一方の側面７３ａが当接する第２ベース（導光部）５７の面（光入射面５７ａ）から第２ベース（導光部）５７に入射する。入射した光は、第２ベース（導光部）５７の意匠部材５３との対向面である光出射面５７ｂから意匠部材５３の光入射面５３ｂ内に入射し、意匠部材５３の意匠面５３ａが発光する（図３の矢印参照）。 In the present embodiment, since there is a gap between the LED element 61 and the wall 73e, the light emitted from the LED element (light source) 63 is also directly applied to the design member 53 on the wall 73e from the light emitting surface 63a to the opening 73f. It functions as a light-shielding part that prevents the light from entering.
The operation of the above configuration will be described. As shown in FIG. 3, the light emitted from the light emitting surface 63a of the LED element 63 passes through the opening 73d of the light source hole 73a of the convex portion 73, and the second base (guide) with which one side surface 73a of the convex portion 73 abuts. The light enters the second base (light guide) 57 from the surface (light incident surface 57 a) of the light portion 57. The incident light is incident on the light incident surface 53b of the design member 53 from the light emitting surface 57b which is the surface facing the design member 53 of the second base (light guide portion) 57, and the design surface 53a of the design member 53 Emits light (see arrow in FIG. 3).

上記構成の光装飾具によれば、以下の様な効果が得られる。
（１）ＬＥＤ素子６３を開口７３ｄより奥まった位置に配置し、凸部７３の光源穴７３ａの開口７３ｄ側の壁７３ｅを遮光部とし、第２ベース５７を光出射面５７ｂが意匠部材５３に対向し、ＬＥＤ素子（光源）６１からの光が入射し、入射した光を意匠部材５３へ導く導光部としたことにより、ＬＥＤ素子（光源）６３から直接意匠部材５３へ入射する光がない。よって、光っている部分と光っていない部分との境界が明瞭となる。 According to the light ornament having the above-described configuration, the following effects can be obtained.
(1) The LED element 63 is disposed at a position deeper than the opening 73d, the wall 73e on the opening 73d side of the light source hole 73a of the convex portion 73 is used as a light shielding portion, and the light emitting surface 57b serves as the design member 53. Opposing the light from the LED element (light source) 61 is incident, and the light guide unit guides the incident light to the design member 53, so that there is no light directly incident on the design member 53 from the LED element (light source) 63. . Therefore, the boundary between the shining part and the non-shining part becomes clear.

更に、本実施形態では、導光部として機能する第２ベース５７は、意匠部材５３に２色射出成形法により形成されているので、第２ベース５７の光出射面５７ｂが意匠部材５３の光入射面５３ｂに密着しているので、光っている部分と光っていない部分との境界が更に明瞭となる。   Furthermore, in the present embodiment, the second base 57 that functions as the light guide portion is formed on the design member 53 by the two-color injection molding method, so that the light emission surface 57b of the second base 57 is the light of the design member 53. Since it is in close contact with the incident surface 53b, the boundary between the shining part and the non-shining part becomes clearer.

（２）導光部として機能する第２ベース５７は、拡散材を含有しているので、ムラがない均一な光を意匠部材５３へ入射させることができる。
尚、本発明は上記実施形態に限定するものではない。上記実施形態としては、光源としてＬＥＤ素子を用いた例で説明を行ったが、光源としては、白熱球、蛍光灯、ＥＬ（エレクトロルミネッセンス）であってもよい。 (2) Since the second base 57 functioning as a light guide part contains a diffusing material, uniform light without unevenness can be incident on the design member 53.
In addition, this invention is not limited to the said embodiment. Although the above embodiment has been described with an example in which an LED element is used as a light source, the light source may be an incandescent bulb, a fluorescent lamp, or EL (electroluminescence).

また、ＬＥＤ素子（光源）６３の出射面、出射方向は光らせたい部位により適宜選択すれば良い。例えば、上記実施形態では、ＬＥＤ素子６３の光出射面は、第２ベース５７と対向する面としたが、第１ベース５５と対向する面を光出射面としてもよい。この場合、導光部は、第１ベース５５となり、少なくともＬＥＤ素子（光源）６３と意匠部材５３との間の光の経路に沿って配置され、ＬＥＤ素子６３から出射する光が直接意匠部材５３へ入射するのを防止する遮光部は、凸部７３のＬＥＤ素子６１の光出射面から開口７３ｆまでの壁７３ｅとなる。   Moreover, what is necessary is just to select suitably the output surface of LED element (light source) 63, and the output direction according to the site | part which wants to shine. For example, in the above embodiment, the light emitting surface of the LED element 63 is the surface facing the second base 57, but the surface facing the first base 55 may be the light emitting surface. In this case, the light guide portion becomes the first base 55 and is disposed along at least the light path between the LED element (light source) 63 and the design member 53, and the light emitted from the LED element 63 is directly applied to the design member 53. The light-shielding portion that prevents the light from entering is a wall 73e from the light emitting surface of the LED element 61 of the convex portion 73 to the opening 73f.

尚、この場合においても、ＬＥＤ素子６１と壁７３ｅとの間に隙間があるので、光出射面６３ａから開口７３ｄまでの壁７３ｅも、ＬＥＤ素子（光源）６３から出射した光が直接意匠部材５３へ入射するのを防止する遮光部として機能する。
更に、本実施形態の導光部として機能する第２ベース５７は、意匠部材５３に２色射出成形法により形成されているので、第２ベース５７の光出射面５７ｂが意匠部材５３の光入射面５３ｂに密着していたが、第２ベース５７の光出射面５７ｂが意匠部材５３の光入射面５３ｂに密着してる必要はない。第２ベース５７の光出射面５７ｂと、意匠部材５の光入射面５３ｂとの間には、若干の隙間がある対抗関係であってもよい。 Even in this case, since there is a gap between the LED element 61 and the wall 73e, the light emitted from the LED element (light source) 63 is also directly applied to the design member 53 on the wall 73e from the light emitting surface 63a to the opening 73d. It functions as a light-shielding part that prevents the light from entering.
Furthermore, since the second base 57 functioning as the light guide portion of the present embodiment is formed on the design member 53 by the two-color injection molding method, the light emission surface 57b of the second base 57 is incident on the design member 53. The light emitting surface 57b of the second base 57 does not need to be in close contact with the light incident surface 53b of the design member 53. There may be a facing relationship in which there is a slight gap between the light emitting surface 57b of the second base 57 and the light incident surface 53b of the design member 5.

また、上記実施形態では、光装飾具として、車両のガーニッシュに適用した例で説明を行ったが、他に、家の外装や内装等の車両以外の光装飾具にも適用できる。   Moreover, although the said embodiment demonstrated by the example applied to the garnish of a vehicle as a light ornament, it can apply also to light ornaments other than vehicles, such as a house exterior and interior.
