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.

Claims

1. An optoelectronic component having luminescent beam-emitting characteristics comprising:

an elongated body having electrical connections, said body being transparent at a body exit thereof;

a luminescent beam generating means in the body for generating light for exiting from said body at said body exit;

wherein the component defines a central hollow at a top of the body, located at the transparent body exit along a longitudinal axis of the body for deflecting the light into a horizontal plane, whereby the central hollow slopingly extends toward all sides of the body.

2. An optoelectronic component as in claim 1, wherein the shape of the central hollow is conical.

3. An optoelectronic component as in claim 1, wherein the shape of the central hollow is pyramidal.

4. An optoelectronic component as in claim 1, wherein the shape of the central hollow is polygonal.
