Abstract

Die Erfindung betrifft eine LED-Beleuchtungseinrichtung, die wenigstens eine LED (1) mit einer Hauptabstrahlrichtung in der Lichtabgabe der LED (1) und einen Lichtlenkkörper (3) umfaßt, der aus einem Lichtleiter gebildet ist und wenigstens eine Lichtaustrittsfläche (12,14,18) aufweist, wobei Licht der LED (1) in den Lichtlenkkörper (3) eingekoppelt wird und der Lichtlenkkörper (3) wenigstens einen Teil des Lichts so umlenkt, daß es den Lichtlenkkörper (3) durch die Lichtaustrittsfläche (12,14,18) mit einer Lichtverteilung verläßt, die asymmetrisch bezüglich der Hauptabstrahlrichtung der LED ist, dadurch gekennzeichnet, daß die Lichtverteilung in einer Schnittebene, in welcher die Hauptabstrahlrichtung der LED (1) liegt und welche die Lichtaustrittsfläche (12,14,18) schneidet, eine Lichtverteilungskurve definiert, die ein Hauptmaximum (13) und wenigstens ein Nebenmaximum aufweist, wobei das Hauptmaximum (13) asymmetrisch bezüglich der Hauptabstrahlrichtung der LED (1) liegt.
