颜色可调的照明系统、灯和照明设备
摘要：
本发明涉及颜色可调的照明系统(10)、灯(100)以及照明设备。颜色可调的照明系统包括发射第一预定颜色(B)的光的光源(20)，并且包括用于将第一预定颜色的光转换成第二预定颜色(A)的光的发光材料(30)。该颜色可调的照明系统进一步地包括遮挡装置(40，42)，其布置用于防止至少部分由光源所发射的光照射到发光材料上。光源、发光材料和/或遮挡装置可从第一位置变化到第二位置。在第一位置，该颜色可调的照明系统布置用于遮挡至少部分发光材料免受第一预定颜色的入射光的照射。在第二位置，与第一位置相比，该颜色可调的照明系统布置用于遮挡更少的发光材料免受由光源所发射的第一预定颜色的光的照射。根据本发明的方法的效果在于，遮挡装置、发光材料和/或光源确定由颜色可调的照明系统所发射的第二预定颜色的光量，这确定了颜色可调的照明系统的颜色。
摘要（英）：

The invention relates to a color-tunable illumination system (10), to a lamp and to a luminaire. The color-tunable illumination system comprises a light source (20) emitting light of a first predefined color (B), and comprises a luminescent material (30) for converting light of the first predefined color into light of a second predefined color (A). The color-tunable illumination system further comprises shielding means (40, 42) arranged for preventing at least part of the light emitted by the light source to impinge on the luminescent material. The light source, the luminescent material and/orthe shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color. In the second situation the color-tunable illumination system is arranged for shielding less of the luminescent material to the lightof the first predefined color emitted by the light source compared to the first situation. The effect of the measures according to the invention is that the shielding means, luminescent material and/or the light source determine an amount of light of the second predefined color emitted by the color-tunable illumination system which determines a color of the color-tunable illumination system.
