A COLOR TUNABLE LIGHTING ASSEMBLY, A LIGHT SOURCE AND A LUMINAIRE

摘要

A color tunable lighting assembly (100), a light source and a luminaire are provided. The color tunable lighting assembly (100) comprises a light emitter (110), a luminescent layer (108) and a temperature controlling means (106). The light emitter (110) emits light (112) of a first color distribution. The luminescent layer (108) receives light (112) emitted by the light emitter (110). The luminescent layer (108) comprises luminescent material to absorb a portion of the light (112) of the first color distribution and to convert a portion of the absorbed light into light (102) of a second color distribution. The second color distribution is dependent on the temperature of the luminescent layer (108). The temperature controlling means (106) actively controls a temperature of the luminescent layer (108) to obtain a light emission by the color tunable lighting assembly. The light emission has a specific color distribution.
