Abstract
An optoelectronic component having a basic housing or frame and at least one semiconductor chip, specifically a radiation-emitting or -receiving semiconductor chip, in a cavity of the basic housing. In order to increase the efficiency of the optoelectronic component, reflectors are provided in the cavity in the region around the semiconductor chip. These reflectors are formed by virtue of the fact that a filling compound filled at least partly into the cavity is provided, the material and the quantity of the filling compound being chosen in such a way that the filling compound, on account of the adhesion force between the filling compound and the basic housing, assumes a form which widens essentially conically from bottom to top in the cavity, and the conical inner areas of the filling compound serve as reflector.
