Lighting devices using feedback-enhanced luminescent devices are disclosed. A light emitting diode disposed between feedback elements (FE-LED) may be used as a light emitting element in the lighting devices. The light emitting element may be coupled to a light distribution element. In one aspect, the light emitting diode may be an organic light emitting diode (FE-OLED).
