Abstract

An optoelectronic component for improved distribution of light in a horizontal plane has an elongated body (2) with a central hollow (6) at a top portion (3) thereof, a base (4), and an electrical connection (5). An internally emitted luminescent beam (7) is deflected by the central hollow (6) through transparent portions of the body into the horizontal plane. A height of the component (1) is thereby reduced, and light is fed into light guides more efficiently. Light distribution on all sides is made possible by a conical central hollow. The luminescent beam (7) can be concentrated into four beams by using a pyramidal hollow (6), so that the luminescent beam (7) can be efficiently fed into four light guides that cross at that location.
