SURFACE STRUCTURED LIGHT-EMITTING DIODE WITH IMPROVED CURRENT COUPLING

摘要

The light output from a light emitting diode (100), comprising a light generating layer (20) and a relatively thick, transparent current dispersing layer (30), is improved by a vertical structuring of the surfaces of the current dispersing layer (30) and, by means of a second electrical contact layer (50) with a distributed lateral structure, an essentially homogeneous coupling of electrical current in the current dispersing layer (30) can be obtained.
