Abstract

Es wird angestrebt, das von vorn auftreffende Fremdlicht nicht nur im geringen Umfang eines etwaigen hierfür zusätzlich angebrachten kleinen Katzenauges aufzufangen und zurückzuwerfen, sondern hierfür die gesamte Fläche des Frontscheinwerfers zu nutzen. The aim is not only to strike the ambient light from the front to a small extent any additional attached for this small cat’s eye to catch and throw back, but the to use the entire area of the headlight.

Erreicht wird dies durch einen Zweiradscheinwerfer (1), dessen Schutzscheibe (4) Formgebungselemente (5) aufweist, die von vorn auftreffendes Fremdlicht (8) um ca. 180° reflektieren, wobei die Lichtachse (8') des reflektierten Fremdlichts -abweichend von der geneigt nach unten gerichteten Lichtkegelachse (7') des Scheinwerferlichts (7)- parallel zur Zweiradlängsachse verläuft. This is achieved by a two-wheel headlight (1), the Protective screen (4) shaping elements (5) has from the front Reflect extraneous light (8) by approx. 180 °, the light axis (8 ') of the reflected extraneous light - deviating from that inclined downwards directed light cone axis (7 ') of the headlight (7) - parallel to Longitudinal bicycle axis runs.
