Abstract:
A projector and an illumination system thereof are provided. The illumination system includes an excitation light source group, a phosphor wheel, a light combiner element and a first lens group. The excitation light source group provides a first beam and has a first optical axis. The phosphor wheel has a reflection region and a wavelength conversion region. The light combiner element is disposed between the excitation light source group and the phosphor wheel and has a dichroic portion and a reflection portion. The first lens group is disposed between the light combiner element and the phosphor wheel. The first lens group has a second optical axis. The illumination system is provided in the projector to reduce the number of optical elements, thereby reducing the cost and volume.

Claim (Index 1):
An illumination system, comprising:\n an excitation light source group, adapted to provide a first beam, wherein the excitation light source group has a first optical axis; a phosphor wheel, having a reflection region and a wavelength conversion region; a light combiner element, disposed between the excitation light source group and the phosphor wheel, wherein the light combiner element has a dichroic portion and a reflection portion; and a first lens group, disposed between the light combiner element and the phosphor wheel, wherein the first lens group has a second optical axis, the first beam passes through the dichroic portion and the first lens group and is transmitted to the reflection region of the phosphor wheel, wherein the first beam passes through the first lens group via a first side of the second optical axis, the reflection region of the phosphor wheel reflects the first beam, the reflected first beam passes through the first lens group and is transmitted to the light combiner element, wherein the first beam reflected from the reflection region passes through the first lens group via a second side of the second optical axis and is transmitted to the reflection portion of the light combiner element, wherein the first optical axis of the excitation light source group and the second optical axis of the first lens group are not coaxial with each other.
