This area is larger than that of a certain prism portion 22d. Thus, the amounts of light reflected from the area A and the area B can be made substantially the same. Similarly, the height dc of the prism portion 22 d in the region C is formed higher than the height db of the prism portion 22 d in the region B.
- the area of the prism portion 22 d in the area C in contact with the incident light from the lamp 21 is in the area B by the difference between the height db and the height dc.

Abstract
Description
このため、特許文献1及び特許文献2に記載された技術は、導光板と透過体との間隔が一定である場合には、透過体を均一に発光させることができるが、導光板と透過体との間隔が一定でない場合には、均一に発光させることができなかった。
また、本発明の他の目的は、透過体である樹脂材料の表面に加飾フィルムを取り付ける構成において当該フィルムの張力差によるクラックを解消し、意匠性がより高く、商品価値がより向上した車両用発光部品を提供することにある。
また、本発明の他の目的は、加飾照明の機能性を向上し、かつ、発光領域の質感を高めた車両用発光部品を提供することにある。
上記の構成では、反射部をなす切込みの深さを、透過体と導光体との間隔に応じて変えることにより、反射部での反射光の光量が上記の間隔に応じて変動する。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、単位面積当たりの反射部の個数を、透過体と導光体との間隔に応じて変えることにより、反射部での反射光の光量が上記の間隔に応じて変動する。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、透過体の裏面に形成された凹部又は凸部により、拡散光の光量が透過体と導光体との間隔に応じて調整される。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、透過体の裏面に取り付けられた光拡散シートにより、拡散光の光量が透過体と導光体との間隔に応じて調整される。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、透過体内に含有されている散光材料により、拡散光の光量が透過体と導光体との間隔に応じて調整される。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、透過体内に含有されている黒色顔料により、吸収光の光量が透過体と導光体との間隔に応じて調整される。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成では、ホルダ中、導光体を囲んでいる部分の色の明暗度合いを透過体と導光体との間隔に応じて変えることにより、吸収光の光量が上記の間隔に応じて変動する。これにより、車両用発光部品の発光領域を均一に発光させることが可能となる。
上記の構成において、透過体を成す樹脂基材は、意匠性の観点から曲面を有するように構成されている。一方、加飾フィルムは、樹脂基材の曲面部において、この曲面部に追随しうる最大限の引張展開率となるように調整されている。この場合、加飾フィルムの引張展開率を高くすると、装飾層に損傷が発生するという問題が起きる。このため、樹脂基材の曲面部において、これに追随しうる最大限の引張展開率になるように調整すれば、損傷の発生を抑制し、より高い意匠性を有する車両用発光部品を提供することが可能となる。また、透過光調整層の非透過部と透過部との境界部にグラデーション処理がなされている。これにより、境界部付近の発光をぼんやりとしたおだやかな発光とし、演出効果を高めることが可能となり、意匠性がより向上する。なお、グラデーション処理については、上記の境界部に近接している近接部分にのみ施されているとよい。
上記の構成では、グラデーション部中、引張展開率がより高くなった領域が、引張展開率がより低くなった領域よりも幅広となっていることにより、加飾フィルムの装飾層における光線透過率の変化や損傷の発生をより効果的に抑制することが可能となる。
上記の構成では、グラデーション部が加飾フィルム中、引張展開率が最大となる部分から外れた位置に設けられていることにより、加飾フィルムの装飾層における光線透過率の変化や損傷の発生をより一層効果的に抑制することが可能となる。
上記の構成では、発光領域を構成する透過体の色調と、透過体の前方位置に積層される加飾フィルムの透過光調整層のうち、非透過部の色調とを同系色としているため、乗員が車内側から発光領域を見たときに、透過光調整層において非透過部と、非透過部と隣り合う透過部との境界線が透けて見えてしまうのを抑制することができる。具体的に説明すると、非透過部は、表面処理によって通常黒色で着色され、透過部は透明色から構成されているため、未発光時に車内側から見たときに、意匠層を介して黒色の非透過部と、透明な透過部越しに見える通常白色樹脂からなる透過体との境界線が透けて見えてしまうことがあった。なぜなら、発光照明の輝度を確保するためには、意匠層の膜厚を通常小さくする必要があったためである。このとき、黒色の非透過部と白色の透過体との色調の差を小さくすべく、非透過部の色調と透過体の色調とを同系色とすることで、この境界線をぼやかすことができる。この結果、発光照明の機能性を向上したままで、発光領域の質感を高めることが可能となる。
具体的に説明すると、本発明によれば、導光体に形成された反射部での反射光の光量を、透過体と導光体との間隔に応じて変えることで発光領域が均一に発光するようになる。
また、本発明によれば、透過体の裏面に形成された凹部又は凸部、透過体の裏面に取り付けられた光拡散シート若しくは透過体内に含有されている散光材料により、拡散光の光量を透過体と導光体との間隔に応じて変えることで発光領域が均一に発光するようになる。
また、本発明によれば、透過体内に含有されている黒色顔料により、吸収光の光量を透過体と導光体との間隔に応じて変えることで発光領域が均一に発光するようになる。さらにまた、ホルダ中、導光体を囲んでいる部分の色の明暗度合いを透過体と導光体との間隔に応じて変えれば、同様に、吸収光の光量が上記の間隔に応じて変わり、発光領域が均一に発光するようになる。
また、本発明によれば、加飾フィルムの透過光調整層の非透過部と透過部との境界部にグラデーション処理がなされていることにより、加飾フィルムの装飾層における損傷の発生を抑制し、意匠性を向上させることが可能となる。このとき、引張展開率がより高くなった領域が、引張展開率がより低くなった領域よりも幅広となっていれば、加飾フィルムの装飾層における損傷の発生をより効果的に抑制することが可能となる。さらにまた、グラデーション部が加飾フィルム中、引張展開率が最大となる部分から外れた位置に設けられていれば、加飾フィルムの装飾層における損傷の発生をより一層効果的に抑制することが可能となる。
また、本発明によれば、発光領域を構成する透過体の色調と、透過体の前方位置に積層される加飾フィルムの透過光調整層のうち、非透過部の色調とを同系色としていることにより、乗員が車内側から発光領域を見たときに、非透過部と透過部との境界線が透けて見えてしまうのを抑制することが可能である。このとき、グラデーション部において非透過部と隣り合う透過部側から非透過部に向かって、透過部から離れるほど表面濃度が濃くなっていれば、非透過部と透過部との境界線をより一層ぼやかすことができ、車内側から見たときには当該境界線を一層隠蔽することが可能となる。
以下、本発明の一実施形態(以下、本実施形態)について図面を参照しながら説明する。なお、以下の説明において、車両の前後方向とは、通常走行時の前後方向を意味し、また、車両の内側(以下、単に内側ともいう)とは、車室側(車両の室内側)のことを意味し、車両の外側(以下、単に外側ともいう)とは、車外側のことを意味している。さらに、以下の説明において、上側(下側)とは、車両本体に組み付けられた状態での上側(下側)を意味する。
本実施形態に係る発光オーナメント1は、図2に示すように、照射体としての光源ユニット20と透過体としてのオーナメント10とを組み合わせて構成されるモジュールであり、ドアライニング本体2に設けられた収容ケース3に取り付けられている。オーナメント10、並びに光源ユニット20を構成するホルダ23及び導光体22のそれぞれは、車両の前後方向に沿って長尺で、長尺方向の一方に向かって先細りに形成された略板状の外形形状を有する。
上記のように構成された発光オーナメント1おいては、ランプ21が点灯すると、ランプ21から入射する光が、導光体22のプリズム部22dによって反射されて導光体22から面状に出射する。オーナメント10にある発光領域10aが、導光体22から出射する光を透過しつつ拡散させることで、面状に所定の輝度にて発光することとなる。
本実施形態に係る発光オーナメント1中、オーナメント10は、曲板状の部材からなり、側方視で略弓形に屈曲している。このため、発光オーナメント1が車両に取り付けられた状態(すなわち、利用状態)では、オーナメント10の裏面と導光体22の出射面22aとの間隔が位置に応じて相違する。すなわち、利用状態にある発光オーナメント1では、オーナメント10が、導光体22との間隔が異なる部位を有することになる。
(1)ランプ21からの入射光のうち、導光体22のプリズム部22dにて反射する反射光の光量を調整するケース
(2)オーナメント10において拡散する光の光量を調整するケース
(3)光源ユニット20からの光のうち、吸収される分の光量を調整するケース
(4)光源ユニット20からの光のうち、遮光される分の光量を調整するケース
以下、各ケースについて説明する。
本ケースは、表面輝度調整部の一つとして反射光調整部が導光体22に設けられているケースである。反射光調整部としては、導光体22の裏面に形成された切込み部からなる複数のプリズム部22dが挙げられる。以下、反射光調整部としてプリズム部22dを利用する場合を例に挙げて説明する。
このように、ランプ21からの距離に応じてプリズム部22dの高さdが設定されている理由を次に述べる。例えば、領域A、領域B及び領域Cにあるプリズム部22dの高さdが同じである場合、入射光が、領域Aのプリズム部22dによってオーナメント10側に反射することで、領域Bのプリズム部22dに到達する光量は少なくなる。さらには、領域Cのプリズム部22dに到達する光量は、領域A及び領域Bよりもランプ21から離間しているため少なくなる。これにより、プリズム部22dによって反射して導光体22から出射される光が均一性を有しないものとなるため、ランプ21から離れた領域におけるプリズム部22dの高さを高くする必要がある。
同様に、領域Cにあるプリズム部22dの高さdcは、領域Bにあるプリズム部22dの高さdbよりも高く形成されている。このようにプリズム部22dが形成されていることで、その高さdbと高さdcの差の分、領域Cにあるプリズム部22dにおけるランプ21からの入射光に接触する面積が領域Bにあるプリズム部22dにおけるその面積よりも増える。このようにして、導光体22の領域A、領域B及び領域Cからから出射する光量を略均一にすることができる。
このように、ランプ21からの距離に応じてプリズム部22dのピッチpが設定されている理由を次に述べる。上記のように、領域A、領域B及び領域Cにあるプリズム部22dの高さd及び隣接するプリズム部22dのピッチpが同じである場合、プリズム部22dによって反射して導光体22から出射される光は、均一性を有しないものとなる。
オーナメント10の発光領域10aと導光体22の出射面22aとが平行に設けられている場合には、導光体22から光が均一に出射することによって、発光領域10aから光が均一に出射することとなる。
しかし、図6(a)のVIB-VIB断面図である図6(b)に示すように、オーナメント10が内反りしており、オーナメント10の発光領域10aと導光体22とが平行に配置されていない場合には、発光領域10aから出射する光量の均一性が保てない。
そこで、次に、オーナメント10と導光体22との距離を考慮してオーナメント10を均一に発光させることについて説明する。
図7は、ランプ21からの距離とプリズム部22dの高さdの対応を示す図である。なお、図7に示された仮想線dxは、プリズム部22dとオーナメント10との間隔を考慮せずにランプ21からの距離のみに応じてプリズム部22dの高さdを線形的に変化させた線であり、本実施形態に係るプリズム部22dの高さdと対比するための線である。また、図8は、ランプ21からの距離と隣接するプリズム部22dのピッチpの対応を示す図である。
図8に示すように、領域Aにおける隣接するプリズム部22d間のピッチpaは、ランプ21の近傍側で大きく、領域Bの境界側では小さく設定されている。領域Aにあるプリズム部22dがこのように形成されていることで、プリズム部22dに到達する光に対して反射する光量がランプ21の近傍側において小さくなり、領域Bの境界側では大きくなる。これによって、プリズム部22dから出射する光量を略均一にでき、導光体22を介してオーナメント10から出射する光量(面輝度)を均一にすることができる。
上記実施形態に係るオーナメント10は、ランプ21からの光の指向方向に沿って端部側の領域A,Cが導光体22から離間して形成され、中央の領域Bが導光体22に近接して形成されているものとして説明したが、このような形状に限定されない。
例えば、図9に示すような、ランプ21からの光の指向方向に沿って導光体22における端部側の領域D,Fから近接して形成され、中央の領域Eが導光体22に離間して形成されているオーナメント110であってもよい。このようなオーナメント110であっても、領域Eにおいて、導光体22とオーナメント110とが近接する間隔で配置された場合におけるプリズム部22dの密度及び高さと比較して、高い密度及び高い高さの少なくとも一方に適合するようにプリズム部22dが形成されていればよい。
上記実施形態に係るプリズム部22dは、図3A、図4及び図10(a)に示すように、断面V字形の溝状で形成されているものであれば、オーナメント10に向かって反射する光量が大きくなるため好ましいが、これに限定されない。例えば、反射部として機能するものとして、図10(b)に示すように、断面U字形の溝状に形成されたプリズム部22e、底が短辺となる断面台形の溝状に形成されたプリズム部22fを用いるようにしてもよい。このように形成されたプリズム部22e及びプリズム部22fは、これらを形成するための型の隅の角度が鈍角となるため、プリズム部22e及びプリズム部22fを構成する溝が型に食いつくのを防ぎ、プリズム部22dと比べて離型性が良好である。
また、反射部を構成するものとして、溝状に形成されたプリズム部22d,22e,22fを例に挙げたが、これに限られず、図11に示すドット状に形成されて点在する凹部22gであってもよい。
本ケースは、表面輝度調整部の一つとしての拡散光調整部が設けられているケースである。拡散光調整部としては、例えば、オーナメント10の裏面(発光領域10aの外表面とは反対側に位置する面)に形成された凹部又は凸部、具体的にはシボ加工によって形成される拡散シボが有効である。そして、導光体22とオーナメント10との間隔の大きさに応じて拡散シボの大きさや単位面積当たりの個数を変えることにより、オーナメント10において拡散する光量が調整され、オーナメント10の発光領域10aを均一に発光させることが可能となる。
本ケースは、表面輝度調整部の一つとしての吸収光調整部が設けられているケースである。吸収光調整部としては、例えば、オーナメント10内に含有されている黒色顔料が利用可能である。すなわち、導光体22とオーナメント10との間隔の大きさに応じてオーナメント10中の黒色顔料の含有率が変化する構成であれば、オーナメント10各部で光吸収量が調整される結果、発光領域10aを均一に発光させることが可能となる。
本ケースは、表面輝度調整部の一つとして遮光調整部が設けられているケースである。遮光調整部とは、光源ユニット20からの光のうち、遮光される分の光量を調整するものである。遮光調整部についてより詳しく説明するため、以下、車両用発光部品の第二実施形態を説明する。
第二実施形態では、比較的膜厚の小さい加飾フィルム151を用いることとしたが、膜厚が小さい場合には、透過部(切欠き部K1)と非透過部(遮光部K2)との境界部分が透けて視認される可能性がある。このため、第二実施形態では、オーナメント基材150に黒色顔料を混合してオーナメント基材150と遮光層151bとの色差を近似させている。かかる構成について、以下、より詳しく説明する。なお、以下では、新たな実施形態(第三実施形態)を説明することとするが、第三実施形態は、車両用発光部品各部の形状等の面で上述の実施形態とは異なるものの、基本構成については上述の実施形態と同様である。このため、以下では、第三実施形態に係る車両用発光部品の構成のうち、上述した実施形態と異なる点を中心に説明することとする。
次に、第三実施形態に係るオーナメントユニットの変形例について説明する。なお、以下の説明のうち、上記の実施例に係るオーナメントユニット80と重複する内容については省略することとする。
上記の実施形態では、本発明の車両用発光部品の実施例について説明した。しかし、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定するものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることは勿論である。また、上述した各部材の材質、配置位置、形状等については、本発明の効果を奏するための例に過ぎず、本発明を限定するものではない。
