Abstract: The invention provides a projection apparatus and an illumination system. The projection apparatus includes an illumination system, a light valve, and a projection lens. The illumination system includes at least one laser light source, at least one light separating element, a wavelength conversion element, and a reflective element. The at least one laser light source is adapted to generate at least one laser beam, and the at least one laser beam is adapted to penetrate at least one first coating region of the light separating element. The wavelength conversion element is adapted to convert the laser beam from the light separating element into a converted beam. A second coating region of a reflective surface of the reflective element is adapted to reflect a portion of the laser beam from the wavelength conversion element, and the second coating region and the first coating region are adapted to reflect the converted beam. The portion of the laser beam and the converted beam constitute an illumination beam.

Abstract: An illumination system includes a light integration rod and a light source module. The light integration rod has a light-in end, a light-out end opposite to the light-in end, and phosphor distributed between the light-in end and the light-out end. The light source module is configured to provide a laser beam to enter into the light integration rod through the light-in end thereof. The phosphor is used to convert the laser beam into a first color beam to form an illumination beam. The illumination beam then emits out from the light integration rod through the light-out end thereof. A projection apparatus using the aforementioned illumination system is also provided.
