Abstract: A lighting apparatus includes: a first light source that emits a first light; a first lens that allows the first light to pass through and exit from a first exit face of the first lens; a second light source that emits a second light; and a second lens that is smaller than the first lens and allows the second light to pass through and exit from a second exit face of the second lens. When viewed from the first exit face side: (i) the first exit face has a recess that is recessed inward from a periphery of the first exit face; and (ii) the second exit face is at least partially disposed in the recess.
