Beschreibung
Zusammenfassung:	A reflector LED lamp comprises: a reflector 18 having a spheroidal reflecting surface with an opening provided therein; a plurality of LEDs 44, 46, 48, 50, and 52 arranged in the reflector 18, on a plane perpendicular to an optical axis X of the reflector 18; and a lighting circuit operable to light the plurality of LEDs, wherein the plurality of LEDs are divided into at least a first group (LED 44) and a second group (LED 46, 48, 50, and 52), the first group arranged at a first distance from the optical axis X, the second group arranged at a second distance from the optical axis X, the second distance being longer than the first distance, and while the plurality of LEDs are lit by the lighting circuit, luminous flux per LED is larger in the first group than in the second group.
