PROBLEM TO BE SOLVED: To provide an LED luminaire which can be mounted on a ceiling surface directly, and which improves luminous efficiency of an LED element and radiates light uniformly by securing a sufficient heat radiation effect while reducing trouble and cost of production with a simple structure.SOLUTION: An LED luminaire 100 includes: a fixture body 1 mounted on a surface to be mounted; and a light emitting unit 2 mounted on the fixture body 1. The light emitting unit 2 has a heat sink 23 in which an LED substrate 24 on which a plurality of LED elements 26 are mounted and a power supply circuit 28 for lighting these LED elements 26 are disposed. On the heat sink 23, a groove part 23d for inserting a screw 29 for fixing the LED substrate 24 to the heat sink 23 is provided. The power supply circuit 28 is provided at the heat sink 23 with space between itself and the heat sink 23. |
