A plurality of such LED packages are disposed on the substrate such that a first area and a second area, each determined by vertices corresponding to LED packages, are defined on the substrate.

Such a configuration allows the thermistor to detect, in accordance with the temperature in the area, the temperature of heat transferred from the LED packages, without being affected by heat generated by the FET. This makes it possible to efficiently make temperature corrections to stabilize color temperature and luminance.
