    • The invention relates to an illumination system (10, 20, 30) for illuminating a display device (40) and to a display device (40). The illumination system comprises a light- mixing chamber (50) which comprises a light-exit window (52), a rear wall (54) which is situated opposite the light-exit window (52), and edge walls (56, 58) which extend between the light-exit window (52) and the rear wall (54). A surface (55) of the rear wall (54) is substantially specularly reflective for specularly reflecting light impinging on the surface of the rear wall and having a relatively large angle of incidence with respect to an axis perpendicular to the rear wall. The illumination system further comprises a light source (60, 62) and a plurality of light out-coupling elements (70). The light source emits light into the light-mixing chamber in a direction substantially parallel to the light-exit window. The illumination system further comprises an angularly reflective filter (80) applied at the light- exit window. The angularly reflective filter is constituted of a plurality of substantially transparent layers (81, 82, 83, 84), each layer having a substantially uniform thickness. Each set of two adjacent layers (81, 82, 83, 84) of the angularly reflective filter has different refractive indexes.
    • 本发明涉及一种用于照明显示装置(40)和显示装置(40)的照明系统(10,20,30)。 所述照明系统包括光混合室(50),所述光混合室包括出射窗(52),与所述光出射窗(52)相对的后壁(54)和边缘壁(56,58) 其在光出射窗(52)和后壁(54)之间延伸。 后壁(54)的表面(55)基本上镜面反射,用于镜面反射照射在后壁的表面上的光,并且相对于垂直于后壁的轴线具有相对大的入射角。 照明系统还包括光源(60,62)和多个光出耦合元件(70)。 光源在基本上平行于光出射窗的方向上将光发射到光混合室中。 所述照明系统还包括施加在所述光出射窗处的角度反射滤光器(80)。 角度反射滤光片由多个基本上透明的层(81,82,83,84)构成,每层具有基本均匀的厚度。 角度反射滤光器的每组两个相邻层(81,82,83,84)具有不同的折射率。
