【解決手段】発光パネルアセンブリは、発光パネル(22)の1つまたはそれ以上の表面の中または上に明確に規定された形状の光抽出変形部(109)の均一なまたは可変のパターンを有する発光パネル部材(22)を含む。パネル表面区域から所望の光出力分布を得るため、光抽出変形部(109)のサイズおよび形状に加えて、深さおよび角度を付けられた向きおよび発光の位置または場所は、パネル表面区域の長さおよび/または幅に沿って異なってもよい。焦点合わせされた光源(3)は、発光パネルの光移動区域内にインサート成形されるかまたは鋳造され、特定の用途に合うように、予め定められた光線角度で光移動区域の入力表面上に光を焦点合わせしてもよい。
【選択図】図42
Description
この発明の別の局面に従うと、光抽出変形部は丸くされた側壁を有する。
品であってもよい。また、光移動区域の側を曲げて、光源から発せられた光の一部を発光パネルを介して許容可能な角度でより効率的に反射または屈折してもよい。
ド(LED)、LEDからのチップ、ネオン電球、蛍光灯、遠隔の光源から伝わる光ファイバライトパイプ、レーザもしくはレーザダイオードまたはいずれの他の好適な光源であってもよい。さらに、所望の色つきまたは白色の光出力分布を与えるため、光源3は、多数の色をつけられたLEDまたは多数の色をつけられた放射源の組合わせであってもよい。たとえば、異なる色(赤、青、緑)のLEDまたは多数の色をつけられたチップを備える単一のLEDなどの複数の色づけされた光を用いて、各個別の色づけされた光の強度を変えることにより、白色光またはいずれの他の色づけされた光出力分布を発生してもよい。
ネルから発し、それによりそれらが低い損失で液晶ディスプレイを通過すればより効率的である。
材27は、色付きのフィルム、拡散器またはラベルもしくはディスプレイであってもよく、その一部は、色づけされおよび/またはその上にテキストまたは画像を有し得る透過性のオーバーレイであってもよい。
レイの美しい設計を容易にする態様で光線が発せられる。
区域82との、パネル部材81の接合部に、角度を付けられるかまたは曲げられた反射または屈折表面83が設けられ、パネル部材の長さに沿った1つまたはそれ以上の発光区域84からの発光のために、光源3からの光をパネル部材81の本体の中に反射/屈折する。
が、角度をつけられた周方向端縁部分117を有する平面の傾斜した反射/屈折表面116と、関連づけられる、角度をつけられた端壁および側壁118および119とを含む個別の光抽出変形部115を示す。
るにつれてサイズが増加する、図29に示されたものと形状が同じ変形部126を示す。
ドなどの焦点合わせされた光源である。これに代えて、そのような光源は、LED、白熱灯または、光源からの光を集めてその光を焦点合わせする一体型の集光器145(図16を参照)を有する他の光源であってもよい。いずれの場合も、光源からの光は、パネルの断面積のかなりの部分にわたって発光パネル7の光入力端縁18に入るために許容できる角度で光を方向づける光移動区域6の入力面146上に予め定められたパターンで好ましくは焦点合わせされる。
プレイを前方照明するのにパネルアセンブリを用いることが可能になり、前述の態様で透過性パネル部材を通してディスプレイが見える。
きが、前記パネル表面の長さおよび幅に沿って異なる、(1)に記載のパネルアセンブリであってもよい。
方照明のため、前記パネル部材の前記裏面側から光を反射および屈折するように形作られる、(20)に記載のパネルアセンブリであってもよい。
レイを含む、(48)に記載のパネルアセンブリであってもよい。
