Abstract

A light-emitting component includes a light-emitting element and a housing with a cavity. The housing includes a housing material that absorbs at least 80 percent of light in the visible range. The cavity is formed by a limiting wall, formed by a housing surface, and a plane of the element. The light-emitting element arranged within the cavity of the housing and positioned above the element plane includes an emission side located opposite to the element plane. The cavity is at least partially filled with a transparent material composed of a first material and a second material, wherein the first material at least partially covers the limiting wall, and the second material at least partially covers the emission side. A boundary surface is formed between the first material and the second material. A first refractive index of the first material is smaller than a second refractive index of the second material.
