Abstract
Description
OD値が1以上3.5以下である表皮材と、任意のパターンを有する遮光層と、透明な成形体とが順に積層され、
光源が点灯したときの、表皮材の発光部と非発光部との色差ΔEが50以上である。
ここで、Δa*、Δb*、ΔL*は、CIE1976色空間における、発光部10aのa*,b*,L*値と、非発光部10b(つまり遮光層12が形成されている部分)のa*,b*,L*値との差で求められる値である。
1)光源の光色は変えずに、表皮材の色を変える
2)表皮材の色は変えずに、光源の光色を変える
上記1)は、たとえば光色が白であれば、表皮材の色をアイボリーなど黄色がかった白色系や、白以外の色にするといったことである。上記2)は、さらに、たとえば次の2通りが挙げられる。
2−1)光源の光色そのものを変える
2−2)加飾成形品に着色層を設けることで光色を変える
上記2−2)の着色層の位置は、表皮材10と成形体13との間であって、発光部10aに相当する位置であればよい。また、着色層としては、たとえばセロファン、紙、着色透明の印刷層などを用いることができる。なお、成形体13を着色透明樹脂で成形して着色層としてもよい。
使用カメラ:TOPCON SR−5000(株式会社トプコン製)
(面測定が可能な分光放射計)
光源:LED、輝度最大約500000cd/m2
加飾成形品表面とカメラまでの距離:350〜400mm
図3(a)〜(f)に示す、すべてのパターンを有する加飾成形品1を用いた。蛍光灯下において、加飾成形品1の裏面から光源2を点灯させ、カメラ4で加飾成形品表面の画像を撮影した。その画像において、表皮材における発光部と非発光部を指定することで、発光部と非発光部のそれぞれの色データ(L*、a*、b*)を抽出した。色データに基づいて、表皮材における発光部と非発光部との色差ΔEを算出した。なお、光源の輝度は300000cd/m2で一定とした。
視認性は、3波長光源下の室内で光源2を点灯させ、カメラ4と同位置から加飾成形品1のパターン(アイコン)を目視し、その見やすさを○、△、×として評価した。○は明瞭にアイコンを視認できるレベル、△はアイコンが点灯していることを視認できるが、細部や輪郭がぼやけて明確に視認できないレベル、×はアイコンが点灯していることを視認するのが難しい、もしくは至近距離でないと視認できないといったレベルとした。
結果を表1に示す。
