A luminaire comprises a housing (2) with a light emission window (3). The housing (2) accommodates a plurality of opto-electronic elements (5, 5', ...; 6, 6', ...; 7, 7', ...) and a plurality of collimating elements (15; 16; 17). In operation, the opto-electronic elements (5, 5', ...; 6, 6', ...; 7, 7', ...) emit visible light. Each of the collimating elements (15; 16; 17) has an optical axis (25; 26; 27) and is associated with an opto-electronic element (5, 5', ...; 6, 6', ...; 7, 7', ...). According to the invention, the opto-electronic element (5; 6; 7) is positioned substantially eccentrically with respect to the optical axis (25; 26; 27) of the collimating element (15; 16; 17) with which the opto-electronic element (5; 6; 7) is associated. Preferably, at least one further opto-electronic element (5'; 6'; 7') is associated with at least one collimating element (15; 16; 17). Said further opto-electronic element (5'; 6'; 7') is either positioned substantially eccentrically or coincides with the optical axis (25; 26; 27) of the collimating element (15; 16; 17) with which the further opto-electronic element (5'; 6'; 7') is associated. Preferably, the optical axes (25; 26; 27) of the collimating elements (15; 16; 17) are directed so as to be substantially parallel to each other. Preferably, the collimating elements (15; 16; 17) are Fresnel lenses and the opto-electronic elements (5, 5', ...; 6, 6', ...; 7, 7', ...) are light-emitting diodes. |
