    • 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。

    • The invention relates to a lighting system (LSI) which comprises a plurality of light engines (LEa1,1, LEa2,1, LEa3,1) and a system-exit window (OS). Each light engine comprising a first predetermined number of light emitting diodes, a second pre-determined number of dichroÊc beam splitters, and an engine-output window. The light engine superposes light emitted by the light emitting diodes via at least one dichroÊc beam splitter on the engine-output window. The lighting system further comprises a plurality of light guides (LGa1,1, LGa2,1, LGa3,1) for guiding light emitted by the light engines towards the system-exit window. The light guides comprise a light-guide-output window (OGa1,1, OGa2,1, OGa3,1) The plurality of light-guide-output windows is arranged in an array constituting the system-exit window. The light guides enable the light engines to be located remotely from the system-exit window. This enables an effective cooling of the light emitting diodes of the light engines while allowing the light-guide-output windows to be stacked adjacent in the system-exit window.
    • 本发明涉及一种照明系统(LSI),其包括多个光引擎(LEa1,1,1La2,1,1,...,LE1,3,1, / SUB>)和系统退出窗口(OS)。 每个光引擎包括第一预定数量的发光二极管,第二预定数量的二向分束器和发动机 - 输出窗口。 光引擎将由发光二极管发出的光通过至少一个二向分束器叠加在发动机 - 输出窗上。 照明系统还包括用于引导光的多个光导(LGa1,1,1L,LGa2,1,1L,LGa3,1,1) 由光引擎发射到系统出口窗口。 光导包括导光 - 输出窗口(OGa1,1,1,OGa2,1,1,OGa3,1,1)。多个 的光导输出窗口被布置在构成系统出口窗口的阵列中。 光导使光引擎远离系统出口窗口。 这使得能够有效地冷却光引擎的发光二极管,同时允许光导 - 输出窗口在系统出口窗口中相邻堆叠。
