Abstract

In einen Optikkörper (3) wird das von einer Lichtquelle (1) in einen kegelförmigen Raumbereich mit einer sich in Z-Richtung erstreckenden Zentralachse (ZS) abgegebe Licht eingekoppelt. Er ist in einer Schnittebene, die durch die Z-Richtung und eine hierzu senkrechten X-Richtung aufgespannt ist, im wesentlichen V-förmig. Die jeweils Aussen- und Innenwandbereiche aufweisenden V-Schenkel (5, 6) sind zur Zentralachse symmetrisch angeordnet und konvergieren zu einem Basisteil (8) des Optikkörpers. Zur Erzielung einer gleichförmigen Lichtverteilung weist der Basisteil eine Vertiefung (10) mit einer solchen Tiefe auf, dass sich eine Lichtquelle, deren Lichtkegel einen Scheitelwinkel von nahezu 180° besitzt, so weit in sie hinein erstreckt, dass im wesentlichen ihr gesamtes Licht in den Optikkörper eingekoppelt wird. Teile der eintretenden Randbereiche des Lichtkegels werden auf Aussenwandbereiche des Basisteils umgelenkt, dort reflektiert und dann durch mehrfache Reflexionen zwischen einander gegenüberliegenden Teilabschnitten der Innen- und Aussenwandbereiche eines jeden der V-Schenkel von der Zentralachse weg nach außen verteilt.

Figure imgaf001
The light emitted by a light source (1) into a conical space region with a central axis (ZS) extending in the Z direction is coupled into an optical body (3). It is in a sectional plane, which is spanned by the Z-direction and a direction perpendicular thereto X-direction, substantially V-shaped. The respective outer and inner wall regions having V-legs (5, 6) are arranged symmetrically to the central axis and converge to a base part (8) of the optic body. To obtain a uniform light distribution, the base part has a depression (10) with such a depth that a light source whose light cone has a vertex angle of nearly 180 ° extends so far into it that substantially all of its light enters the optical body is coupled. Parts of the entering edge regions of the light cone are deflected onto outer wall regions of the base part, reflected there and then distributed outwards by multiple reflections between opposing subsections of the inner and outer wall regions of each of the V legs from the central axis.
