Abstract
An illumination system including a laser light source module, a wavelength conversion module and a control module is provided. The laser light source module simultaneously emits a first and second laser light beams, where a peak wavelength of the first laser light beam is greater than that of the second laser light beam. The control module is connected to the laser light source module and the wavelength conversion module, respectively. In a first time interval, the control module controls an amount of luminous flux of the first laser light beam to be greater than an amount of luminous flux of the second laser light beam. In a second time interval, the control module controls the amount of luminous flux of the first laser light beam to be smaller than the amount of luminous flux of the second laser light beam. A projection apparatus and an illumination control method are provided.
