LUMINAIRE
The luminaire for tubular lamps has a housing (1) having a light emission plane (2) and several lighting units (10) accommodated in the housing. Each unit (10) has a pair of opposed side reflectors (12), which are possibly connected to lamellae (15) and which bound the light emission window (11) of the unit. Between two adjacent units (10) a possibly light transmitting, e.g. perforated, plate (20) is present, which fills the light emission plane (2). The plate (20), the side reflectors (12) and the lamellae (15) may constitute an assembly.
