PROBLEM TO BE SOLVED: To provide a luminaire and a lens capable of suppressing light unevenness of a light distribution pattern while controlling light distribution and restraining the reduction in lighting efficiency in a case where at least one optical axis of an outgoing beam from an LED to be incident in a lens incidence part does not agree with a symmetric axis of the lens.SOLUTION: The luminaire comprises an LED and a lens that light-distribution controls the light radiated from the LED. The LED includes two or more light-emitting faces with different optical axes of a wavelength conversion member; at least one optical axis or all optical axes of the light-emitting faces do not agree with the symmetric axis of the lens. The emission surface of the lens includes: a central region including a region on the symmetric axis; an outer peripheral area including the circumference of the emission surface; and an intermediate region putted between the central region and the outer peripheral area. The intermediate region is a high light diffusion region in which light diffusivity is higher in comparison with the central region and the outer peripheral area. |
