An LED lamp includes: a substrate; a cluster of LEDs, which are arranged two-dimensionally on the substrate; and an interconnection circuit, which is electrically connected to the LEDs. The LEDs include a first group of LEDs, which are located around the outer periphery of the cluster, and a second group of LEDs, which are located elsewhere in the cluster. The interconnection circuit has an interconnection structure for separately supplying drive currents to at least one of the LEDs in the first group and to at least one of the LEDs in the second group separately from each other.
