Description
Claims (12)
- 光源の少なくとも1つの領域から1つの色の少なくとも可視光を放射する、ロービーム機能を備える自動車ヘッドライト用のLEDコリメータ素子であって、
当該LEDコリメータ素子は、動作中に放射される光の主要部分が、当該LEDコリメータ素子の放射角範囲内に直接的に放射され得る、少なくとも1つの光源のようなLEDを有し、当該LEDコリメータ素子は、当該LEDコリメータ素子の前記放射角範囲内に放射されない光を前記放射角範囲内に偏向するコリメータを含み、当該LEDコリメータ素子は、所定の非均一な明るさ分布が、コリメータ切断平面に対して並びに当該LEDコリメータ素子の放射の主方向に対して直交して定められる当該LEDコリメータ素子の放射平面内で達成可能であるよう、少なくとも前記コリメータ切断平面に関して非対称に構成され、少なくとも1つのフィルタが、前記ロービーム機能を実現するときに、明暗遮断よりも下に位置する交通空間の地域が、異なる色の可視光で所定地域内で照明され得るよう、前記コリメータの少なくとも1つの領域内に配置される、LEDコリメータ素子。 - これらのフィルタの少なくとも1つは、高輝度の領域からの光が、低輝度の領域からの光よりも、異なるスペクトル組成、より好ましくは、より大きな黄色部分又は青色部分を有するように配置される、請求項1に記載のLEDコリメータ素子。
- 非均一な明るさの分布が、前記コリメータの第一縁部に直接的に高輝度があり、前記LEDから離れる前記コリメータの前記縁部の側に実質的に光がないように設計される、請求項1に記載のLEDコリメータ素子。
- 迷光、より具体的には、黄色の迷光が、前記明暗遮断より上の領域に達するよう、少なくとも1つの散乱フィルタが、前記コリメータの縁部に沿って配置される、請求項1に記載のLEDコリメータ素子。
- 第一縁部が形成される前記コリメータの第一地域が、放射の主方向に対して、第二地域よりも少なく傾斜される、請求項1に記載のLEDコリメータ素子。
- 二次光学系が、放射の主方向において前記コリメータ孔の背後に配置され、前記二次光学系は、照明されるべき空間内に放射光を結像する、請求項1に記載のLEDコリメータ素子。
- 前記LEDは、有機又は無機LEDである、請求項1に記載のLEDコリメータ素子。
- 異なる特性を有する複数のLED素子が、前記コリメータ内に配置される、請求項1に記載のLEDコリメータ素子。
- 前記フィルタは、前記コリメータの縁部の領域内に配置される、請求項1に記載のLEDコリメータ素子。
- 前記フィルタは、当該LEDコリメータ素子の前記筐体の機械的基準に対する前記明暗遮断の幾何学的位置を高精度に決定するために基準地点として働く、請求項1に記載のLEDコリメータ素子。
- 請求項1乃至10に記載の少なくとも1つのLEDコリメータ素子を有する照明装置。
- 前記ロービーム機能を実現するとき、前記明暗遮断より下の前記交通空間は、色に関して本質的に影響を受けていない光を備える第一領域を別として、色に関して所定の影響を受けている光、具体的には、青色又は黄色光を備える少なくとも第二領域がある、請求項11に記載の照明装置。
