    • The invention relates to a color-tunable illumination system (10; 12; 14) and a luminaire. The color-tunable illumination system comprises a first light source comprising a first set of light emitting diodes (21, 24), and a second light source comprising a second set of light emitting diodes (31, 37, 34). Both the first and second light source emit light of substantially a first predefined color into a light mixing chamber (60). The light mixing chamber further comprises a first luminescent material (50) converting light of the first predefined color into light of a second predefined color. The first light source is positioned with respect to the first luminescent material for illuminating the first luminescent material with a first flux of light being part of the light emitted by the first light source into the light mixing chamber. The second light source is positioned with respect to the first luminescent material for illuminating the first luminescent material with a second flux of light being part of the light emitted by the second light source into the light mixing chamber. The first flux is different from the second flux. The effect of the measures according to the invention is that a change in the intensity of the light emitted by the first light source relative to the intensity of the light emitted by the second light source results in a change of the color emitted by the color-tunable illumination system.
    • 本发明涉及一种可调色照明系统(10; 12; 14)和照明装置。 颜色可调照明系统包括包括第一组发光二极管(21,24)的第一光源和包括第二组发光二极管(31,37,34)的第二光源。 第一和第二光源都将基本上第一预定颜色的光发射到光混合室(60)中。 光混合室还包括将第一预定颜色的光转换成第二预定颜色的光的第一发光材料(50)。 第一光源相对于第一发光材料定位,用于照射第一发光材料,第一光束是由第一光源发射到光混合室中的光的一部分。 第二光源相对于第一发光材料定位,用于用作为由第二光源发射到光混合室中的光的一部分的第二光束照射第一发光材料。 第一通量与第二通量不同。 根据本发明的措施的效果是,由第一光源发射的光的强度相对于由第二光源发射的光的强度的变化导致颜色发射的颜色的变化, 可调照明系统。

    • The invention relates to an illumination system (2), aluminaire (2), a backlighting system and a display device. The illumination system according to the invention comprises a light exit window (30) for emitting light from the illumination system, and a diffuse reflecting screen (40) arranged opposite the light exit window. The illumination system further comprises a light source (20) which is arranged for indirect illumination of the light exit window via the diffuse reflecting screen. The light source is arranged near an edge of the light exit window on an imaginary plane (22) arranged substantially parallel to the light exit window and emits light away from the light exit window. The illumination system further comprises an edge wall (62) comprising a specular reflecting mirror (60) being concavely shaped for reflecting at least part of the light emitted by the light source towards the diffuse reflecting screen. The effect of the illumination system according to the invention is that the use of the specular reflecting mirror enables a controlled reflection of the part of the light emitted by the light source towards the diffuse reflecting screen.
    • 本发明涉及具有用于发光的光出射窗(30)的照明装置(2,8)。 照明装置还包括与光出射窗口相对布置并且包括结构化反射表面的漫反射屏(40,46)。 照明装置还包括用于经由漫反射屏间接照射光出射窗的光源(20)。 光源设置在光出射窗的边缘附近,该虚拟平面(22)基本上平行于光出射窗设置并从光出射窗口射出光。 照明装置还包括布置在漫反射屏和光出射窗之间的边缘壁(62)。 边缘壁包括镜面反射镜(60),其被成形为用于将由光源发射的光的至少一部分反射到漫反射屏。 使用镜面反射镜能够使由光源发射的光的一部分受到控制地反射到漫反射屏幕,并且由于漫反射屏幕包括结构化的反射表面,镜面反射被隔离,否则当光线 以放射角度在漫反射面上撞击。 因此,照明装置在光出射窗上具有改善的均匀性。
