First Claim
Patent Images
1. A lighting device comprising:
- a light source comprising at least;
a first feedback layer adapted to receive and reflect light;
a first electrode formed on the first feedback layer;
one or more semiconducting layers formed over the first electrode, at least one of the one or more semi-conducting layers comprising luminescent material;
a second electrode disposed over the one or more semiconducting layers; and
a second feedback layer adapted to receive and reflect light disposed over the second electrode; and
;
a light distribution element disposed adjacent to one or both of the first feedback layer and the second feedback layer and adapted to distribute light emitted therefrom.

Abstract
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).
