A luminaire having a lamp ( ) and at least one concavely curved reflector arranged, seen in the radiation direction, behind or to the side behind the lamp ( ). To the side of the lamp ( ) color filters ( ) are so arranged that only the light radiated by the lamp ( ) to the side against the at least one concave reflector ( ) is altered in its color composition by means of the color filters ( ). The light radiated in the radiation direction intended for the illumination is not altered in color.

Luminaire

A luminaire having a tube-shaped gas discharge lamp ( ) contains at least one concavely curved reflector ( ) arranged&mdash;seen from the region to be illuminated&mdash;neighboring the lamp ( ), and at least one partially light permeable diffusor ( ) arranged&mdash;likewise seen from the region to be illuminated&mdash;neighboring the lamp ( ) but before the reflector ( ). The diffusor ( ) and the reflector ( ) bound next to the lamp ( ) at least one light entry surface and run together at their ends away from the lamp ( ) such that they enclose at least one light chamber ( ), the ratio between the width (a) of a light chamber and the height (b) of a light entry surface being at least 4:1. Further, there may be provided means for the attainment for a uniform light density over the width of the reflector.
