Abstract
A projection device, a light source system and a projection method thereof are provided. A portion of the light-emitting units are controlled to provide a light beam as the first light beam. It is detected whether characteristic parameters of the light-emitting units providing the light beam reach a preset value. When the preset value is not reached, the light-emitting units providing the light beam are disabled, and the remaining light-emitting units are controlled to provide the back-up light beam as the first light beam. A portion of the first light beam is converted into a second light beam. The first light beam of which the wavelength is not converted and the second light beam are combined to generate an illumination beam. The illumination beam is converted into an image beam. The image beam is converted into a projection beam.
