Abstract

Längliches optisches Element (5, 15) für in Längsrichtung hintereinander angeordnete Leuchtdioden (10), das eine lichtstreuende Charakteristik aufweist und im Querschnitt im Wesentlichen U-förmig ausgebildet ist, wobei der die beiden Seitenschenkel bzw. seitlichen Bereiche (6, 16) miteinander verbindende Mittelschenkel bzw. mittlere Bereich (8, 18) der U-Form eine Einwölbung nach innen aufweist und Anordnung zur Lichtabgabe (9, 19) mit dem ersten länglichen optischen Element (5, 15) und einem zweiten länglichen optischen Element (2) sowie Leuchtdioden (10), wobei in Lichtabstrahlrichtung der Leuchtdioden (10) das erste optische Element (5, 15) mit der Öffnung der U-Form in Richtung der Leuchtdioden (10) direkt vor den Leuchtdioden (10) angeordnet ist und von dem zweiten optischen Element (2) umgeben wird.

Figure imgaf001
An elongated optical element (5, 15) for light-emitting diodes (10) arranged one behind the other in the longitudinal direction and having a substantially U-shaped cross-section, wherein the two side limbs or lateral regions (6, 16) connect to one another Central leg or middle region (8, 18) of the U-shape has a concave inward and arrangement for emitting light (9, 19) with the first elongated optical element (5, 15) and a second elongated optical element (2) and light-emitting diodes (10), wherein in the light emission direction of the light-emitting diodes (10), the first optical element (5, 15) with the opening of the U-shape in the direction of the light emitting diodes (10) is arranged directly in front of the light emitting diodes (10) and of the second optical element (2) is surrounded.
