Title: LIGHT-EMITTING COMPONENT AND METHOD FOR PRODUCING A LIGHT-EMITTING COMPONENT
Abstract:
The invention relates to a light-emitting component, having a light-emitting element and a housing with a cavity. The housing comprises a housing material, which absorbs at least 80 percent of light in the visible range. The cavity is formed by a bounding wall and a plane of the element, the bounding wall being formed by a surface of the housing. The light-emitting element is arranged inside the cavity of the housing and is positioned above the plane of the element. The light-emitting element has an emission side lying opposite the plane of the element. The cavity is at least partially filled with a transparent material. The transparent material is composed of a first material and a second material, the first material at least partially covering the bounding wall and the second material at least partially covering the emission side. A boundary surface is formed between the first material and the second material. A first index of refraction of the first material is smaller than a second index of refraction of the second material.
