Abstract

Es wird eine Leuchte mit langgestreckter Lichtquelle, mindestens einem quer zur Lampenachse gekrümmten Reflektor und einer Abdeckung aus durchsichtigem Material vorgeschlagen. Die Abdeckung (5) ist zur Lichtaustrittsfläche (4) der Leuchte (1) nach innen zur Lampe (4) hin versetzt und als Prismenabdeckung ausgebildet. It becomes a lamp with an elongated Light source, at least one across Lamp axis curved reflector and a cover made of transparent material suggested. The cover (5) is for Light exit surface (4) of the lamp (1) offset inwards towards the lamp (4) and designed as a prism cover.
