Claim 0:
1. A light source device comprising:
a first light source to emit first color light;
a second light configured to emit second color light;
a wavelength converter to convert at least a portion of the first color light into a third color light;
a light incident element to which the first color light, the second color light, and the third color light enter;
a first filter to reflect the first color light toward the wavelength converter; and
a second filter to reflect the second color light toward the light incident element,
wherein:
the first filter and the second filter separately disposed on an optical path of the third color light between the wavelength converter and the light incident element, and
an optical axis of first color light emitted directly from the first light source is located on a first plane and an optical axis of second color light emitted directly from the second light source is located on a second plane perpendicular to the first plane in three-dimensional coordinate system.
