Abstract

A luminaire for general lighting includes an illuminant having a first light emission surface and a second light emission surface. The illuminant includes an organic, light-generating region. The first light emission surface and the second light emission surface are arranged at two mutually opposite main surfaces of the illuminant. A first light emerges at the first light emission surface during the operation of the illuminant, and a second light emerges at the second light emission surface during the operation of the illuminant. The first light and the second light differ from one another with regard to color and/or color temperature. The first light and the second light leave the luminaire in mutually different emission directions.
