PROBLEM TO BE SOLVED: To provide an LED lighting fixture which suppresses temperature rise in a circuit board of a main light source caused by an auxiliary light source, and which can prevent increase in size in the circuit board of the main light source.SOLUTION: A fixture body 20 for accommodating a power supply part 26 includes: a first light source part 22 on which a first LED 24 is mounted on a first circuit board 23; and a second light source part 31 on which a second LED and a third LED are mounted on a second circuit board electrically connected to the first circuit board 23. By providing the first circuit board 23 and the second circuit board separately, even when the second LED and the third LED of the second light source part 31 are lighted, heat can be prevented from being transmitted to the first circuit board 23 of the first light source part 22, and also, as the first light source part 22 and the second light source part 31 can be lighted mutually exclusively, the first light source part 22 can be made to be a main light source and the second light source part 31 can be made to be an auxiliary light source. Also, as the second LED and the third LED are different kinds, various kinds of light distribution control can be performed depending on the combination. |
