Abstract
【解決手段】照明装置は、発光半導体型の少なくとも2つの光源のアレイと、少なくとも第1の照明素子15および第2の照明素子16のアレイと、を備える。各照明素子15、16は、光源のうちの1つと関連付けられ、かつ、光源により放射された光ビームが、照明素子15、16の形状に依存する形状を呈するようにして、関連する光源により点灯される。第1の照明素子15は、下底を有する台形形状であり、第2の照明素子16は、台形形状に対して、部分的に相補的な形状を有し、かつ、少なくとも下底の長さ程度の長さだけ離れ、互いに平行であり、下底の2つの両端部から延びる、2つの縁部を備える。
【選択図】図3a
Description
図2、図3aおよび図4に示すように、本発明に係る照明装置10は、照明素子12のアレイ11と、発光半導体、例えば発光ダイオード(LED)型の光源14のアレイ13と、を備える。
図7は、全てのLEDがオンである場合の、照明装置10の図を示している。
本発明は、ビームを、連続する逆等脚台形に離散化することにより、曲がりくねった道において、カットオフが、車両の軌道に従う、ロービームモードのための光ビームを生成する利点を有する。
