Abstract

In verschiedenen Ausführungsbeispielen wird eine Beleuchtungsanordnung (100) bereitgestellt, aufweisend eine Lichtquelle (110) zum Bereitstellen von Laserlicht (130) und ein diffus reflektierendes Material und/oder ein phosphoreszierendes Material und/oder ein fluoreszierendes Material, welches auf einer Fläche (108) derart in der Beleuchtungsanordnung (100) angeordnet ist, dass von der Lichtquelle (110) bereitgestelltes Licht (130) auf das Material trifft, wobei die Fläche einen Hohlkörper bildet mit einer oder mehreren Teilflächen, die derart zumindest teilweise einander zugewandt angeordnet sind, dass von auf einer Teilfläche angeordnetem Material reflektiertes oder erzeugtes Licht zumindest teilweise auf Material trifft, welches auf derselben oder einer anderen Teilfläche der Fläche angeordnet ist, und sowohl die Einstrahlung des Laserlichts wie auch die Abstrahlung des reflektierten oder erzeugten Lichts über dieselbe Oberfläche der einer oder mehreren Teilflächen erfolgt.
