Abstract
An illumination system including a coherent light source device, a light delivery module, and a light wavelength conversion module is provided. The coherent light source device includes a light emitting source and a light collimating element. The light emitting source is adapted to emit at least one coherent light beam. The light collimating element is located on a transmission path of the at least one coherent light beam from the light emitting source and collimates the at least one coherent light beam. The light delivery module is located on a transmission path of at least one coherent light beam from the light collimating element and includes a first lens. The first lens has a lens array surface adapted to diverge any of the coherent light beam from the light collimating element. A projection apparatus is also provided.
