  • Patent number: 6661033
    Abstract: On an upper side there is a structured output coupling layer with flanks which are aligned at an angle between 60° and 88° with respect to a layer plane and which form boundaries for output coupling areas provided for the emergence of radiation and offset from one another. The output coupling areas are formed as flat truncated cones and can be rippled or zigzagged at the flanks, in order to increase the probability that the radiation produced strikes an outer interface of the output coupling layer more steeply than at a limiting angle of total reflection.
