Abstract

Eine Leuchte weist wenigstens eine Lampe (11) sowie ein erstes optisches Element (14-1) zur Umlenkung von in dieses eintretenden und wieder aus diesem austretenden Lichtstrahlen (15), derart, daß deren Austrittswinkel kleiner als ein vorbestimmter Grenzaustrittswinkel ist, auf. Das optische Element (14-1) weist einen plattenförmigen Kern (16) aus transparentem Material auf, der an einer Seite mit Mikroprismen (17) mit einer länglichen Struktur besetzt ist, die sich unter Bildung von Furchen (18) - von ihrer Wurzel ausgehend - verjüngen. Ferner ist ein zweites optisches Element (14-2) vorgesehen, das wie das erste optische Element (14-1) aufgebaut und parallel zu diesem angeordnet ist, wobei sich die Mikroprismen (17) des zweiten optischen Elements (14-2) quer zu den Mikroprismen (17) des ersten optischen Elements (14-1) erstrecken.

Figure imgaf001
A luminaire has at least one lamp (11) and a first optical element (14-1) for deflecting light beams (15) entering and exiting therefrom, such that their exit angle is smaller than a predetermined limit exit angle. The optical element (14-1) has a plate-shaped core (16) made of transparent material, which is occupied on one side with microprisms (17) with an elongated structure which, starting from its root, forms furrows (18) - rejuvenate. Furthermore, a second optical element (14-2) is provided, which is constructed like the first optical element (14-1) and arranged parallel thereto, wherein the microprisms (17) of the second optical element (14-2) transversely to extend the microprisms (17) of the first optical element (14-1).
