Abstract
An illumination system for use in a projector is provided. The illumination system comprises a first light source, a first timing controlling unit, a curved reflecting component and a wavelength converting component. The first light source provides a first wavelength light, while the first timing controlling unit divides the first wavelength light into a first timing portion and a second timing portion. The curved reflecting component comprises a focal point. The wavelength converting component is disposed at the focal point for converting the first timing portion of the first wavelength light into a second wavelength light.
