PROBLEM TO BE SOLVED: To provide a luminaire which reduces color unevenness and luminance unevenness of a cover member and can achieve uniformity of chromaticity and luminance while being capable of improving performance properties.SOLUTION: A luminaire comprises: a substrate 21; a plurality of luminous elements 22 which is mounted onto the substrate 21, is arrayed in rows on circumferences of at least two substantially concentric circles having radii different from each other and emits white light; a plurality of luminous elements 22 which is arrayed in a row between the rows of the plurality of luminous elements 22 emitting the white light on a circumference of a circle substantially concentric with the circles and emits light other than the white light; and a cover member 5 which covers the plurality of luminous elements 22 with a predetermined separation distance and has diffusibility and light permeability while being directed with the light emitted from the luminous elements 22. |
