Description
Infrarot-Filter f ! ir Strahler, vorzugsweise für Scheinwerfer Die Neuerung betrifft ein aus Filterschicht und Trägerkörper bestehendes Infrarot-Filter für Strahler, vorzugsweise für Scheinwerfer. Infrarot-Filter werden hauptsächlich für Scheinwerfer benötigt. Für Scheinwerfer wurden diese Filter bisher in Form von Planscheiben ausgebildet, während bestimmte Strahlungsverteilungen, die eventuell gefordert wurden, durch zusätzliche Optiken, z. Bo Linsen, Streuer u. dgl. vor oder hinter dem Filter vorgesehen wurden. Bei diesen Systemen treten Strahlungsverluste durch Absorption im Filter und in der Optik sowie durch Reflexion in dem Raum zwischen Optik und Filter auto Bei dem neuerungsgemäß ausgebildeten Filter wird ein Minimum an Absorptions-und Reflexionsverlusten dadurch erzielt, daß die Filterschicht auf einen Trägerkörper aufgebracht ist, der als optisches System, vorzugsweise als Streuer, ausgebildet ist, so daß durch seine Formgebung eine gewünschte Strahlungsverteilung erzielbar isto In den Fig. 1 und 2 ist ein AusfÜhrungsbeispiel der Neuerung dargestellte Das Infrarot-Filter, das aus einem Trägerkörper 1 mit einer Filterschicht besteht, ist gekrümmt ausgebildet und besitzt auf seiner inneren Oberfläche eine Riffelung 2 zur Herbeiführung einer definierten Streuung. Es sind selbstverständlich auch andere Ausführungsformen der Neuerung denkbar, die sich hauptsächlich nach der geforderten Lichtverteilung des Strahlers richten. So ist es unter Umständen zweckmäßig, das Filter als Planacheibe mit einer einseitigen Riffelung auszubilden bzw. für einen anderen Fall das Filter selbst als optische Linse in der reise auszubilden, daß man es mit gekrümmten Oberflächen, beispielsweise in der Art einer Sammellinse, ausbildet,Infrared filter f! ir spotlights, preferably for headlights Die The innovation concerns an infrared filter consisting of a filter layer and a carrier body for spotlights, preferably for headlights. Infrared filters are mainly used required for headlights. For headlights, these filters were previously in the form of Face plates formed while certain radiation distributions that may were required by additional optics, e.g. Bo lenses, spreaders and the like in front of or behind the filter. Radiation losses occur in these systems by absorption in the filter and in the optics as well as by reflection in the space between Optics and filter auto With the newly designed filter, a minimum is required at absorption and reflection losses achieved in that the filter layer on a carrier body is applied, which acts as an optical system, preferably as a spreader, is designed so that a desired radiation distribution through its shape achievable iso In Figs. 1 and 2, an exemplary embodiment of the innovation is shown The infrared filter, which consists of a carrier body 1 with a filter layer, is curved and has a corrugation on its inner surface 2 to bring about a defined spread. Of course there are too other embodiments of the innovation conceivable, which are mainly after the required Align the light distribution of the spotlight. So it may be useful the To train filters as a planar disk with a one-sided corrugation or for one other case to train the filter itself as an optical lens in the trip that it is done with curved surfaces, for example in the manner of a converging lens, trains,
