    摘要: The invention relates to alightsource and an illumination system. The light source (10) comprises a light emitter (20) and a light conversion element (30). The light emitter emits visible light of a first color through the light conversion element in a direction away from the light source. The light conversion element comprises a photoluminescent material (40) for converting at least a part of the light of the first color into light of a second color different from the first color. The light source further comprisescon-version material (42) for converting at least a part of ambient light impinging on the conversion material into light of a third color (Ba) different from the second color. When the light emitter emits light, the color of the light emitted is mainly a mixture of the light of the first color and light of the second color. When the light emitter does not emit light, the color of the light emitted by the light source is determined by the reflected ambient light, light of the second color and light of the third color. As such, the color of the light source can be tuned when the light emitter does not emit light and can, for example, be made substantially identical to the color of the light emitted when the light emitter emits light.
