Description
Die Erfindung bezieht sffih auf einen Spurlichtprojektor für Kraftfahrzeuge, Motorräder u. dgl., der am vorderen oder hinteren Ende, oder an beiden Enden des Fahrzeuges feststehend oder drehbar angebracht ist und die durch das Fahrzeug bedingte Spurbreite durch zwei hell und weit sichtbar leuchtende, schmale Streifen auf der Fahrbahn anzeigt. Im Gegensatz zu den bekannten Anordnungen dieser Art, bei denen die Leuchtstreifen ' durch zwei Scheinwerfer erzeugt werden, werden gemäß der Erfindung die Streifen dadurch .hervorgerufen, daß der Spürlichtprojektor als Leuchtkörper eine oder mehrere gäsgefüllte oder luftleere Lampen aufweist, deren Glühfaden' oder Glühfäden unter 90° in V-Form angeordnet sind und durch eine bikonvexe Linse projiziert werden. Weitere Kennzeichen der Erfindung werden darin gesehen, daß der Projektor mit einer noch einem anderen Zweck (Fernlicht, Stadtlicht, Sucherlicht) dienenden Lichtquelle vereinigt ist und daß die in geraden Linien projizierten Lichtstreifen durch ein optisches System entsprechend einer zu befahrenden gekrümmten Bahn dieser gleichlaufend gebogen werden.The invention relates to a track light projector for automobiles, motorcycles and the like, at the front or rear end, or at both ends of the vehicle is fixed or rotatably mounted and the track width caused by the vehicle by means of two bright, narrow stripes on the roadway that are visible from afar. In contrast to the known arrangements of this type, in which the light strips 'Are generated by two headlights, according to the invention, the strips are thereby . Caused that the tracer projector as a luminous body one or more Has gas-filled or evacuated lamps whose filament or filaments are below 90 ° arranged in a V-shape and projected through a biconvex lens. Further Characteristics of the invention are seen in the fact that the projector with a still a light source serving another purpose (high beam, city light, viewfinder light) is and that the streaks of light projected in straight lines through an optical system according to a curved path to be traveled on, this can be bent in the same direction.
Die hierdurch erzielten Vorteile liegen darin, daß die projizierten Lichtstreifen seitlieh scharf begrenzt sind und trotz des die Fahrbahn beleuchtenden Scheinwerf erlichtes gut sichtbar sind. Außerdem verursachen die von dem Projektor erzeugten schmalen Lichtstreifen keine Blendung.The advantages achieved in this way are that the projected light streaks laterally are sharply delimited and illuminated despite the headlights illuminating the road are clearly visible. In addition, the created by the projector cause narrow Streak of light no glare.

Das innen matt und schwarz getönte Lampengehäuse ι trägt in der Lichtaustrittsöffnung 2 eine bikonvexe Linse 3 mit ungefähr acht Dioptrien, welche die in der Lampe 4 glühenden Leuchtfäden 5 in deren geradlinigen Form auf die Straße projiziert. Die Lampe 4, die gasgefüllt oder luftleer sein kann, ist mit einem geradlinig gespannten und unter 90 ° zueinander stehenden Glühfaden 5 versehen. Der Spurlichtprojektor kann auch mit einer noch einem anderen Zweck (Fernlicht, Stadtlicht, Sucherlicht usw.) dienenden Lichtquelle (Lampe, Scheinwerfer, Kotflügellampe) vereinigt werden.The inside matt and black tinted lamp housing ι carries in the light exit opening 2 a biconvex lens 3 with approximately eight diopters, which the filaments 5 glowing in the lamp 4 in their rectilinear shape projected onto the street. The lamp 4, which can be gas-filled or evacuated is with a straight line stretched filament at 90 ° to each other 5 provided. The track light projector can also be used for yet another purpose (high beam, city light, viewfinder light etc.) serving light source (lamp, headlight, fender lamp) are combined.
Am Fahrzeug wird der Projektor 1 zwischen den Scheinwerfern 7 genau in der Fahr-On the vehicle, the projector 1 is positioned between the headlights 7 exactly in the
zeuglängsachse mittels eines geeigneten Halters befestigt. Der Halter 8 ist derart ausgebildet, daß er ein Neigen des Projektors in senkrechter Ebene und ein Schwenken desselben in' waagerechter Ebene gestattet. Fig. 9 veranschaulicht das Bild der leuchtenden Scheinwerfer und des Spurlichtprojektors. Die Scheinwerfer sind auf Nahlicht (Leuchtkegel 9) "gestellt. Die Leuchtstreifen το undtool longitudinal axis attached by means of a suitable holder. The holder 8 is designed in such a way that that he tilts the projector in a vertical plane and swivels it allowed in 'horizontal plane. Fig. 9 illustrates the picture of the luminous Headlights and the track light projector. The headlights are on near light (light cone 9) ". The light strips το and
«o ii, welche in der Verlängerung der äußeren seitlichen Kotflügelkanten verlaufen, werden durch die Strahlenbündel 12 und 13 des Spurlichtprojektors ι derart auf die Straße projiziert, daß die nach dem Fahrzeug zu liegenden Enden der Leuchtspur ungefähr 4 bis . S m vor dem Fahrzeug beginnen. Die Spuren sind daher vom Führersitz aus über die Motorhaube hinweg ohne Anstrengung gut sichtbar.«O ii, which in extension of the outer lateral fender edges are running through the beam 12 and 13 of the track light projector ι projected onto the street in such a way that the ends of the tracer located after the vehicle are approximately 4 to. Start S m in front of the vehicle. The traces are therefore easily visible from the driver's seat over the bonnet without any effort.
Für Fahrzeuge mit großem Radstand, wie Omnibusse, Post- oder Lastkraftfahrzeuge, kann das Spurlicht durch breiter gelegte Leuchtstreifen genau auf die Fahrspur der Hinterräder eingerichtet werden.For vehicles with a large wheelbase, such as buses, mail or trucks, the lane light can be exactly on the lane of the Rear wheels to be set up.
Die Wirkung des Spurlichtprojektors kann dadurch noch erweitert werden, daß vor diesem und auf der Querstange, auf welcher der Projektor drehbar angebracht ist, ein optisches System feststehend angeordnet wird, welches bei seitlicher Drehung des Spurlichtprojektors die Strahlenbündel derartig reflektiert, daß diese der zu befahrenden Wegbiegung entsprechend gekrümmt, also bogenförmig projiziert werden.The effect of the track light projector can be expanded by the fact that before this and on the crossbar on which the projector is rotatably mounted Optical system is fixedly arranged, which when the track light projector is rotated sideways the bundle of rays is reflected in such a way that these are the ones to be driven on Bend in the path is curved accordingly, i.e. projected in an arc shape.
