Abstract:
1. An illumination system for a projector, comprising: a first light source for providing a first wavelength light; a first timing controlling unit for dividing the first wavelength light into a first timing portion and a second timing portion; a curved reflecting component, having a curved surface, at least one hole, a focal point and an opening, wherein the hole is formed on the curved surface, and the opening is spaced apart from the hole; a second timing controlling unit for dividing the first timing portion of the first wavelength light into a third timing portion and a fourth timing portion, wherein the third timing portion and the second timing portion have the same timing and the second timing unit comprises a rotary disk that passes through the opening to be partly located within the curved reflecting component, the rotary disk comprising at least one converting portion and at least one reflecting portion, and a wavelength converting component formed on the at least one converting portion and disposed at the focal point for converting the first timing portion of the first wavelength light into a second wavelength light; wherein: the first timing portion of the first wavelength light passes through the hole to the wavelength converting component disposed at the focal point, and the second wavelength light is emitted outwards from the opening of the curved reflecting component and the wavelength converting component is intermittently disposed at the focal point with the rotation of the rotary disk so as to convert the fourth timing portion of the first timing portion of the first wavelength light into the second wavelength light, and the third timing portion is reflected on the at least one reflecting portion to become the second timing portion.
