A phosphor device (40, 45) of an illumination system (4) is provided. The illumination system (4) emits a first waveband light (L1) and has an optical path (P). The phosphor device (40, 45) includes a first section (401, 451) and a first phosphor agent (402). The first phosphor agent (402) is coated on the first section (401, 451). After the first waveband light (L1) is received by the first phosphor agent (402), the first waveband light (L1) is converted into a third waveband light (L3), and the third waveband light (L3) is directed to the optical path (P), so that the third waveband light (L3) is separated into at least two color lights (C1, C2) along the optical path (P). |
