PROBLEM TO BE SOLVED: To prevent color unevenness from occurring on an irradiation surface as much as possible, in an LED luminaire in which a light source part is configured by two types of LEDs having different color temperatures.SOLUTION: The LED luminaire includes a light source part 1 comprising by arranging a plurality of substantially square shaped core bodies 13, which comprise by densely arranging four pieces of LEDs 10...10 by forming a cross-shaped gap 13a between these, in a direction going around an optical axis 12, by having an interval between the core bodies 13 adjacent to each other. The core body 13 is configured by two pieces of first LEDs 10a, 10a and two pieces of second LEDs 10b, 10b in which color temperature is different from that of the first LED 10a. Also, in the core bodies 13, two sides x, x on the opposing positions with each other are arranged in a direction orthogonal to a virtual straight line y passing through a center of the optical axis 12 and the gap 13a. |
