Abstract
A light-emitting diode has a lens secured in self-adjusted fashion to a mesa surface of a semiconductor body by means of adhesive. The mesa surface is substantially perpendicular and centered with an emission axis of the light-emitting diode. Preferably, the lens is spherical and the mesa surface has a diameter comparable to or smaller than a diameter of the lens.
