Abstract

The invention relates to an opto-electronic component having a narrow aperture angle. The conventional design of components transmitting radiation or reacting to radiation and concentrating that radiation with the aid of lenses results, on account of the increasing distance between the lens and the semiconductor chip, in increasing component dimensions in the radiating or detecting direction with an increasingly narrow aperture angle. In accordance with the invention, a parabolic or approximately parabolic reflector is provided that is connected to a support strip supporting the semiconductor chip such that the latter is as close as possible to the focal point of the parabolic or approximately parabolic surface of the reflector. The reflector is preferably connected to the support strip by engaging elements and surrounded by a housing.
