    • An illumination system has a plurality of light-emitting diodes (R, G, B), at least one light-collimating section (12,12') arranged along a longitudinal axis (25) of the illumination system. The light-collimating sections merges into a light-mixing section (3) having a plurality of side-faces along the longitudinal axis (25). Light propagation in the light-mixing section is based on total internal reflection. The light-mixing section is provided with a light-exit window (13) emitting light towards an imaginary projection surface normal to the longitudinal axis. An end-portion (5) of the light-mixing section is provided with a prismatic protrusion portion (7) for obtaining a light distribution at the imaginary projection surface such that illumination at a first part of the imaginary projection surface is relatively low while illumination at a second part of the imaginary projection surface is relatively high, the first part being obtained at the same side of the longitudinal axis as the prismatic protrusion portion of the light-mixing section.
    • 照明系统具有多个发光二极管(R,G,B),沿照明系统的纵向轴线(25)布置的至少一个光准直部分(12,12')。 光准直部分合并成具有沿着纵向轴线(25)的多个侧面的光混合部分(3)。 光混合部分中的光传播基于全内反射。 光混合部分设置有朝向垂直于纵向轴线的假想投影表面发射光的光出射窗(13)。 光混合部分的端部(5)设置有用于获得在假想投影表面处的光分布的棱形突起部分(7),使得在假想投影表面的第一部分处的照明相对较低,同时照明 在假想投影表面的第二部分相对较高,第一部分在与光混合部分的棱柱形突起部分的纵向轴线相同的一侧获得。
