LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide a luminaire that facilitates suppression of a temperature rise in light-emitting devices and is capable of uniformizing image of light emitted from the light-emitting devices with a simplified configuration.SOLUTION: A luminaire includes: an attachment part 4 opposed to a wiring accessory Cb disposed on an accessory attachment surface C; a substrate 21 of which a mounting surface is disposed toward the front surface side; and light-emitting devices 22 mounted on the substrate 21. The light-emitting devices 22 are arrayed in a plurality of rows on circumferences of approximately concentric circles having different radii or circumferences of polygonal shapes having different sizes and approximately identical centers. The same number of light-emitting elements 22 are arranged between the adjacent rows while being offset in the circumferential direction.
