Abstract
A projector includes alight source unit including a light source, a luminescent wheel having light source segments receiving light from the light source to emit different wavelength ranges of light, a color wheel separate from the luminescent wheel that has a first transmission area transmitting light, in visible light, existing in a certain range of wavelengths and a second transmission area transmitting light existing in a range of wavelengths broader than that of the light transmitted through the first transmission area and on to which the different wavelength ranges of light from the luminescent wheel are shone, and a control module controlling not only the luminescent wheel and the color wheel so that they are synchronized with each other but also the light source so that the light emitted from the light source is sequentially shone on to the light source segments.
