Fresnel lenses are arranged between a board and an outer lens in such a manner as to face at least one of LED chips. The Fresnel lenses are arranged close to a center of the outer lens in front view. Convex and dome-shaped lenses are arranged between the board and the outer lens in such a manner as to face other light sources of the LED chips. The dome-shaped lenses are arranged more radially outward than the Fresnel lenses in front view. Rear surface 89a of the dome-shaped lenses are arranged to be offset toward the LED chips relative to rear surfaces of the Fresnel lenses.
