Description
ここで「僅かに」が意味することは、SSL装置3によって発せられる光の水平方向の成分が、反射表面5における反射後に、反射によって実質的に変わっていないことを可能にする程に、曲率が十分に小さいことである。例えば、反射表面5は、水平方向H1,H2において、僅かに凹面であり、僅かに凸面であり、僅かに回転楕円面であり、僅かに楕円面であり、僅かに放物面であり、或いは自由表面(自由曲面)に従って僅かに湾曲する、隣接する部分を提示し得る。僅かに湾曲する反射表面5は、より均質で心地良い光ビームをもたらし得る。その上、この構造はDRL1によってもたらされる光ビームが特定の規制基準を満足することを保証する単純な方法であり得る。
Claims (8)
