    • An illumination system (10) for spot illumination comprising a tubular reflector (2) with a reflective inner surface, the tubular reflector (2) having an entrance aperture (7) and an exit aperture (8) being larger than the entrance aperture (7); and a light-source array (1) comprising a plurality of light-sources (13a-c; 30a-d, 31a-d, 32a-d) arranged to emit light into the tubular reflector (2) at the entrance aperture (7) thereof. At least one of the tubular reflector (2) and the light-source array (1) is configured in such a way that each symmetry state of the light-source array (1) is different from any symmetry state of the tubular reflector (2). By avoiding coinciding symmetry states, the occurrence of preferred directions of the emitted light can be reduced, whereby the spatial homogeneity with respect to intensity and, where applicable, color of the emitted light can be improved.
    • 一种用于点照明的照明系统(10),包括具有反射内表面的管状反射器(2),所述管状反射器(2)具有大于入口孔(7)的入口孔(7)和出口孔(8) ); 以及包括多个光源(13a-c; 30a-d,31a-d,32a-d)的光源阵列(1),其布置成在入射孔(7)处将光发射到管状反射器(2) )。 管状反射器(2)和光源阵列(1)中的至少一个被配置成使得光源阵列(1)的每个对称状态不同于管状反射器(2)的任何对称状态 )。 通过避免一致的对称状态,可以减少发射光的优选方向的发生,由此可以改善相对于强度的空间均匀性,并且在适用的情况下可以改善发射光的颜色。
