  • ILLUMINATION SYSTEM AND PROJECTION DEVICE COMPRISING THE SAME
    Publication number: 20140204349
    Abstract: An illumination system and a projection device comprising the same are provided. The projection device comprises an imaging system and the illumination system. The illumination system comprises a first light source, a color wheel and a reflecting mirror. The first light source provides a first wave band light along a first axial direction. The color wheel rotates around a second axial direction. The first axial direction is perpendicular to the second axial direction. A first wave band transforming area is formed around an edge of the color wheel, and the reflecting mirror is disposed adjacent to the edge of the color wheel. When being projected to the first wave band transforming area, the first wave band light is transformed into a second wave band light by the first wave band transforming area and then the second wave band light is reflected by the reflecting mirror.
