Description

Scheinwerfer für Luftschutzzwecke und> zur Erzeugung von blendfreiem Licht für Kraftfahrzeuge Gegenstand der Erfindung ist ein-Scheinwerfer, insbesondere für Luftschutzzwi,-cke sowie zur Erzeugung von - blendfreiem Licht, insbesondere für Kraftfahrzeuge, und zwarvon . jener Art, bei welcher dem Scheinwerfer vor der :Lichtquelle in Abständen voneinander angeordnete Lamellen zugeordnet sind.Headlights for air raid protection purposes and> for generating glare-free Light for motor vehicles The invention relates to a headlight, in particular for air raid protection corners and for generating - glare-free light, in particular for motor vehicles, from. the kind in which the headlight in front of the : Light source are assigned to lamellae arranged at a distance from one another.

Die Erfindung -;geht aus von einem bekannten Scheinwerfer für Luftschutzzwecke, insbesondere für Kraftfahrzeuge, mit vor der Lichtquelle in Abständen voneinander. liegenden parallelen, festen, undurchsichtigen La= mellen, die bei Normalstellung, des Kraftfahrzeuges mit der Refiektorachse so nach vorn geneigt angeordnet sind, daß'die Vorden` kante jeder Lamelle in der gleichen Höhe wie die Hinterkante der darunter befindlichen liegt, und -besteht darin, daß die Oberseite der Lamellen in einem solchen Farbton gehalten ist, daß die von ihr reflektierten gefärbten .Strahlen durch ein vor den Lamellen angeordnetes Farbfilter durch subtraktive Farbmischung absorbiert werden.The invention - based on a known headlight for air raid protection purposes, especially for motor vehicles, with in front of the light source at a distance from each other. lying parallel, solid, opaque slats, which in normal position, of the motor vehicle are arranged with the reflector axis inclined to the front, that 'the front' edge of each slat is at the same height as the rear edge of the underneath lies, and consists in the fact that the top of the slats is kept in such a hue that the colored .Strahlen reflected from it through a color filter arranged in front of the lamellas through subtractive color mixing be absorbed.

Neben den nur einmal vom Reflektor reflektierten und :den unmittelbar von der Lichtquelle kommenden nach oben abgedeckten, etwa in der Kantenverbindungslinie zum Austritt gelangenden Lichtstrahlen sind noch mehrfach vom Reflektor und den Ober- und Unterseiten-der Lamellen reflektierte Strahlen vorhanden. Von diesen werden erfndungsgemäß nur die nach oben austretenden von der Lamellenoberseite gefärbt, und zwar so; daa; sie im an sich bekannten subtraktiven Farbmischungsverfahren durch das vorgesetzte, entsprechend gefärbte Farbfilter aus; gelöscht werden.In addition to those reflected only once by the reflector and: the immediate from the light source coming up covered, approximately in the edge connection line The light rays reaching the exit are still several times from the reflector and the Top and bottom of the slats reflected rays available. Of these, according to the invention, only those emerging from the top of the lamellae are upward colored, like this; daa; they in the known subtractive color mixing process through the front, appropriately colored color filter; to be deleted.

Damit ist ein- allen Ansprüchen genügender 'Scheinwerfer für Luftschutzzweeke geschaffen, bei dem nur blendfreies _Licht erzeugt wird.This means that a spotlight for air raid protection purposes is sufficient for all requirements created in which only glare-free _light is generated.

In -der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt- die Fig. i einen der Erfindung gemäß ausgebildeten Scheinwerfer.In the drawing, an embodiment of the invention is shown, namely, FIG. 1 shows a headlight designed according to the invention.

Fig. a stellt einen Ausschnitt aus Fig. i in vergrößertem Maßstabe dar.FIG. A shows a detail from FIG. I on an enlarged scale represent.

Fig. i stellt .eine bekannte Scheinwerferausbildung dar,- und zwar ist das Paraboloid mit a bezeichnet, der . Glfihfadeii mit b, und von den die Lampe verlassenden Lichtstrahlen sind e die parallelen Lichtstrahlen, die ungehindert austreten, und d die im Winkel zur Lampenachse aus der Lichtquelle austretenden Lichtstrahlen, :die im Filter resorbiert werden. Das Filter ist in Fig. i nur angedeutet und m6.' e= und das Scheinwerferschutzglas mit f .bezeichnet.Fig. I represents. A known headlight training, - namely the paraboloid is denoted by a, the. Glfihfadeii with b, and from which the lamp Leaving rays of light are e the parallel rays of light that are unobstructed emerge, and d emerge from the light source at an angle to the lamp axis Light rays: which are absorbed in the filter. The filter is only indicated in FIG and m6. ' e = and the headlight protection glass is marked with f.

Fig. 2 ist eine vergrößerte Darstellung von Fig. i. Sie soll verdeutlichen, wie die Lichtstrahlen d zwischen den Farbauflagen, die subtfaktive Farbmischung verursachen, auf den Lamellen resorbiert werden.FIG. 2 is an enlarged view of FIG. It should make it clear like the rays of light d between the layers of color, the subtly factual mixture of colors cause to be reabsorbed on the lamellae.
