PROBLEM TO BE SOLVED: To secure sufficient luminous efficiency and radiate light uniformly.SOLUTION: An LED luminaire includes: a fixture body mounted on a surface to be mounted; and a light emitting unit mounted on the fixture body. The light emitting unit has an LED substrate on which a plurality of LED elements (26a, 26b and the like) are mounted. The LED substrate is configured by combining a plurality of LED substrate single bodies (24a and the like). The area of substrate wiring connected to two terminals of these LED elements mounted on the LED substrate differs between substrate wiring 27a connected to a first terminal 26e and substrate wiring 27b connected to a second terminal 26f. |
