Abstract:
1. A light source module, comprising: a monochromatic light source emitting a first color light; a rotating wheel having a light transmitting area and a wavelength transforming area, wherein the wavelength transforming area is coated with a first wavelength transforming material capable of transforming the first color light into a second color light; a filter wheel rotating at a same rotation speed with the rotating wheel, wherein the filter wheel has a first color filter area and a second color filter area respectively corresponding to the light transmitting area and the wavelength transforming area; a dichroic mirror disposed between the rotating wheel and the filter wheel, wherein the dichroic mirror reflects the first color light to the rotating wheel and allows the second color light to pass therethrough; wherein when the first color light is incident onto the light transmitting area, the first color light transmits through the rotating wheel, passes along a first light path, and transmits through the first color filter area, and wherein when the first color light is incident onto the wavelength transforming area, the first color light is transformed into the second color light that passes along a second light path and transmits through the second color filter area.
