Claims (4)
- 複数のLEDを光源とし、透明部材で略板面状に形成された導光レンズと、該導光レンズの背面に近接若しくは密着した状態で配置される反射板と、少なくとも前記導光レンズと前記反射板とを前面から覆うアウターレンズとから成る車両用灯具であって、前記導光レンズには一方の端面から当該導光レンズ内に光を注入し対峙する他の一方の端面から光を射出させる第一の光源が設けられ、前記反射板には前記導光レンズの前記他の一方から射出された光をこの車両用灯具の照射方向に反射する折曲部が設けられると共に、この反射板の板面部には複数の貫通孔が設けられ、該貫通孔の背面側には照射方向をこの車両用灯具の照射方向に略一致させる第二の光源が設けられ、前記導光レンズには、前記反射板の前記貫通孔に対応する位置の表面側及び/又は裏面側に前記第二のLEDグループからの光を制御するためのレンズカットが施されていることを特徴とする車両用灯具。
- 前記導光レンズの表面側若しくは裏面側には、前記第一のLEDグループからの光の前記導光レンズ中を透過している光の一部を反射、拡散して、この車両用灯具の照射方向側に向かわせる光拡散模様が相似形状として形成され、前記光拡散模様は前記第一のLEDグループからの光量の到達量に対応して反射光量がほぼ同一となるようにされていることを特徴とする請求項1記載の車両用灯具。
- 前記光拡散模様は、円形又は多角形の何れかの形状であり、シボ加工、塗装、印刷、或いは凸状或いは凹状に形成してあることを特徴とする請求項2記載の車両用灯具。
- 前記導光レンズには前記光拡散模様が設けられ前記第一の光源からの光により前記光拡散模様および前記折曲部で反射した光が光輝している状態がテールランプ機能であり、前記第二の光源が点灯されることでストップランプ機能とされることを特徴とする請求項2または請求項3のいずれかに記載の車両用灯具。
