The present invention proposes an illumination apparatus (10), comprising a radiation source (11) and a carrier (12) coated with at least two kinds of phosphor provided on at least two regions of the carrier, wherein the irradiation region on the carrier (12) irradiated by the radiation source can switch between the at least two phosphor-coated regions of the carrier. Since the irradiation region on the carrier irradiated by the radiation source (11) can switch between the two regions coated with phosphor, the illumination apparatus disclosed in the present invention can generate light of different color temperatures.
