Abstract
In at least one embodiment of the luminaire (), it includes at least one optoelectronic semiconductor device () and at least one primary optical unit () which is disposed downstream of the semiconductor device () and is spaced apart therefrom. Furthermore, the luminaire () comprises a secondary optical unit () and/or a tertiary optical unit () which is/are disposed downstream of the primary optical unit (). A proportion of at least 30% of radiation emitted by the semiconductor device () passes to the secondary optical unit () and/or to the tertiary optical unit (). Furthermore, the secondary optical unit () and/or the tertiary optical unit () is/are arranged for small-angle scattering of the radiation emitted by the semiconductor device ().
