摘要：the invention relates to a lamp for lighting, with a cavity (5) with one or more atleast partially reflective walls (11,32,76), a first wall (9,30,72)the at least one componentlight and a lichtauskoppelbereich has a cavity and at least one side of the
lichtauskoppelbereich a structure of narrow lichtbrechenden elements (15) in a second,at least partially translucent wall (7,62,74) and one of the first wall and third wall
(11,32,76) inat least one strand which completely or partially reflective is trained and withat least one narrow light source which is arranged outside the cavity so that light of thelight sources on the second wall (7,62,74) in the cavity coupled wi rd, with the narrowlichtbrechenden structures on the first wall (11,32,76), parallel to the light source, and aremarkable rejuvenation cross-section in a plane perpendicular to their line and with theangle (w) between the two straight lines which form the flanks of the column or theapproximieren, is included in a range of 100 to 130, while the second wall (7.62,72) in theopaque area on the light of the lamps (3) into the cavity (5) is coupled, a structure ofnarrow lichtbrechenden elements (15) in parallel to the light source (3), and in a crosssection in a plane perpendicular to the def inierenden line or have a form, and the angle(w) between two straight linesthe flanks of the column form or the approximieren,smaller than the corresponding angles for structures at the first wall.
