Abstract

Die Erfindung betrifft eine Optikbaugruppe, umfassend • ein lichtemittierendes Element (2) welches mehrere in einer Reihe angeordnete Lichtaustrittsaperturen (4) aufweist, die jeweils ein divergentes Strahlenbündel (5) emittieren, wobei die Zentralstrahlen (10) der Strahlenbündel (5) in einer gemeinsamen Bezugsebene (11) liegen und eine gemeinsame erste Ausbreitungsrichtung haben, • einen ersten Wärmeleitkörper (14) mit einer Grundfläche (15), und einer Befestigungsfläche für das lichtemittierende Element und einer Anschlagfläche (16) « ein erstes optisches Element (17), welches wenigstens die Divergenz (7) der Strahlenbündel bezüglich der senkrecht zur Bezugsebene (11) liegenden Richtung verringert, wobei das erste optische Element mit dem ersten Wärmeleitkörper (14) mechanisch verbunden ist, • ein zweites optisches Element (18), welches eine Drehung der Strahlenbündel der einzelnen Emitter jeweils um einen rechten Winkel um die Ausbreitungsrichtung bewirkt, wobei die gedrehten Strahlenbündel das zweite optische Element in einer zweiten Ausbreitungsrichtung (12) verlassen, wobei die Zentralstrahlen der Strahlenbündel nach dem zweiten optischen Element in einer zweiten Ebene (13) liegen, die parallel zur Bezugsebene (11) ist, • ein im Strahlengang nach dem zweiten optischen Element angeordnetes drittes optisches Element (19), welches die Divergenz (8) der vom zweiten optischen Element gedrehten Strahlenbündel der Emitter in einer Richtung senkrecht zur Bezugsebene verringert dadurch gekennzeichnet, dass ein Halter (20) zur Befestigung des dritten optischen Elements am ersten Wärmeleitkörper (14) vorgesehen ist, welcher eine erste Montagefläche (21) aufweist, die mit der Anschlagfläche (16) des ersten Wärmeleitkörpers (14) wenigstens teilweise flächig verbunden ist und eine zweite Montagefläche (22) aufweist, an der das dritte optische Element (19) befestigt ist, wobei die zweite Montagefläche senkrecht zur Bezugsebene (11) und parallel zur Einfallsrichtung (12) der Zentralstrahlen der auf das dritte optische Element fallenden Strahlenbündel ist.
