Abstract
An illumination light generation apparatus includes a light source unit and an emission unit. The light source unit includes first and second light source groups that radiate a plurality of light beams, respectively. The first and second light source groups face each other. The emission unit emits a composite light beam in a predetermined direction and includes a first reflection part that reflects the plurality of light beams radiated from the first light source group, and an emission part that reflects the plurality of light beams reflected from the first reflection part and the plurality of light beams radiated from the second light source group. The emission part generates the composite light beam by reflecting the plurality of light beams radiated from the first light source group and the plurality of light beams radiated from the second light source group in the predetermined direction.
