Abstract
An optoelectronic device comprises a phosphor plate, an optoelectronic chip comprising a layer stack of a first optoelectronic semiconductor layer and a second optoelectronic semiconductor layer, a first electrode, and a second electrode. The optoelectronic chip is attached to the phosphor plate, so that the second optoelectronic semiconductor layer is arranged between the phosphor plate and the first optoelectronic semiconductor layer. The first electrode and the second electrode are arranged on a first main surface of the first optoelectronic semiconductor layer on a side remote from the phosphor plate. The second electrode directly contacts the first optoelectronic semiconductor layer.
