Claims (4)
- レンズとハウジングによって形成された灯室内に、光源となる複数個のLEDが配設された車両用LED灯具であって、前記レンズの灯室内側は頂角を灯室内方向に向けた複数の三角プリズムを略平行に形成した断面鋸歯形状のプリズムレンズが形成されており、前記各三角プリズムを挟んだ該三角プリズムの夫々の側面側に前記複数個のLEDが該LEDの光軸を前記三角プリズムに向けて配設されていることを特徴とする車両用LED灯具。
- 前記プリズムレンズに形成された各三角プリズムの共通する一方の側面で反射されたLED光と各三角プリズムの共通する他方の側面で反射されたLED光とが夫々異なる光学系を構成すると共に、外部から前記灯具内に入射した光が前記各三角プリズムの両側面で順次反射されて再度灯具外に出射される再帰反射の光学系を構成することを特徴とする請求項1に記載の車両用LED灯具。
- 前記プリズムレンズに形成された各三角プリズムの両側面の夫々は、少なくとも一部にハーフミラー膜または金属膜が形成されていることを特徴とする請求項1または2のいずれか1項に記載の車両用LED灯具。
- 前記プリズムレンズに形成された各三角プリズムの共通する一方の側面側に配設されたLEDと、各三角プリズムの共通する他方の側面側に配設されたLEDとは、互いに異なる波長の光を発することを特徴とする請求項1〜3のいずれか1項に記載の車両用LED灯具。
