Abstract: A light source module including first and second light sources, first and second wavelength conversion units, and first and second light splitting units is provided. The first light source emits a first light having a first wavelength. The first wavelength conversion unit converts at least one portion of the first light into a first converted light having a second wavelength. The second light splitting unit allows the lights having the second and third wavelengths to travel through and reflects the light having the first wavelength. The second light source emits a second light having the first wavelength. The second wavelength conversion unit converts at least one portion of the second light into a second converted light having the third wavelength. The first light splitting unit is disposed between the first and second wavelength conversion units and reflects the first wavelength and allows the second wavelength to travel through.

Abstract: A light source module includes a light source, a dichroic unit, a color wheel and a wavelength conversion unit. The light source is configured to emit a light. The dichroic unit is opposite to the light source and configured to reflect a portion of the light as a first illumination light in a first direction and reflect a portion of the light as a second illumination light in a second direction inverse to the first direction. The color wheel is opposite to the dichroic unit and configured to at least receive the first illumination light. The color wheel has a blue filter area, a green filter area and a red filter area. The wavelength conversion unit is opposite to the color wheel and the dichroic unit and configured to at least receive the second illumination light and provide a converted light to the color wheel.
