Abstract

Die Erfindung betrifft eine Leuchte, die eine erste LED (2) und eine zweite LED (4) aufweist, wobei die erste LED (2) und die zweite LED (4) Teile einer Lichtquelle der Leuchte bilden; weiterhin weist die Leuchte eine Platinen-Anordnung (6) auf, wobei die erste LED (2) und die zweite LED (4) auf der Platinen-Anordnung (6) angeordnet sind. Die Platinen-Anordnung (6) weist einen ersten plattenförmigen Abschnitt (8) mit einem ersten planen Oberflächenbereich (82) auf, auf dem die erste LED (2) angeordnet und durch den eine erste Flächennormale (N1) festgelegt ist, sowie einen zweiten plattenförmigen Abschnitt (10) mit einem zweiten planen Oberflächenbereich (102), auf dem die zweite LED (4) angeordnet ist und durch den eine zweite Flächennormale (N2) festgelegt ist; dabei ist ein bzw. der Winkel (W) zwischen der ersten Flächennormalen (N1) und der zweiten Flächennormalen (N2) größer als 0° und kleiner als 180°. Durch eine solche Ausgestaltung der Platinen-Anordnung (6) lässt sich eine Lichtabgabe längs einer gebogen bzw. gekrümmt erscheinenden Linie erzeugen. Außerdem betrifft die Erfindung einen Kühlkörper für eine solche Leuchte.
