Description
Die Erfindung bezieht sich auf die Lichtdurchlaßscheibe an Beleuchtungs- und Reflexionskörpern, insbesondere an Fahrzeugen. Beleuchtungskörper sind die Scheinwerfer sowie Schluß- und Stoppleuchten. Reflexionskörper sind die Rückstrahler.The invention relates to the light transmission disc on lighting and reflection bodies, especially on vehicles. Lighting fixtures are the headlights as well as tail and stop lights. The reflectors are the reflectors.
Diese Lichtdurchlaßscheiben werden durch Schnee und Eis leicht zugedeckt, so daß dadurch ihre Wirkung verhindert wird oder nur mangelhaft zur Geltung kommt. Dieser Nachteil tritt vor allem bei Schneetreiben und bei Fahrten durch verschneites Gelände durch den vom Fahrwind hochgewirbelten Schnee auf.These light transmission panels are easily covered by snow and ice, so that their effect is prevented or only inadequately shown to advantage. This disadvantage occurs especially when there is blowing snow and when driving through snow-covered areas Terrain due to the snow blown up by the wind.
Die Erfindung betrifft eine Einrichtung, die das Haften der Schnee- und Eisschicht an der Lichtdurchlaßscheibe verhindern soll. Das geschieht dadurch, daß die Lichtdurchlaßscheibe durch elektrische Heizkörper, die bei Bedarf leicht angebracht und wieder abgenommen werden können, entsprechend beheizt wird. Dieses geschieht durch Anbringung einer zweiten Lichtdurchlaßscheibe, die mit einem elektrischen Heizkörper versehen ist, vor oder hinter der Lichtdurchlaßscheibe des Beleuchtungs- oder Reflexionskörpers. Die Ausbildung ist zweckmäßigerweise so, daß zwischen beiden Lichtdurchlaßscheiben nur ein verhältnismäßig kleiner Raum zur Beheizung entsteht. Dadurch wird nur eine sehr geringe Energiemenge für die Heizung benötigt. Das so entstandene Heizungssystem wird zugleich mit dem zugehörigen Leuchtsystem eingeschaltet. Reflexionskörper sind den Schlußleuchten gleichzusetzen.The invention relates to a device that the adhesion of the snow and to prevent a layer of ice on the light transmission panel. This is done by that the light transmission panel through electric radiators, which if necessary easily can be attached and removed again, is heated accordingly. This is done by attaching a second light transmission panel, which is connected to an electrical Radiator is provided, in front of or behind the light transmission panel of the lighting or reflection body. The training is expediently such that between the two Light transmission panels only create a relatively small space for heating. This means that only a very small amount of energy is required for heating. That so The resulting heating system is switched on at the same time as the associated lighting system. Reflection bodies are to be equated with the tail lights.
Es ist bereits bekannt, Nummernschilder und Rückblickspiegel von Kraftfahrzeugen zu beheizen. Das heizende Element war dabei fest angebracht, und zwar bei der Nummernschildbeheizung als Heizwendel an der äußeren Kante des Nummernschildes und bei dem Rückspiegel in Gestalt von Glühlampen im Innern des Spiegels.It is already known to license plates and rearview mirrors of motor vehicles to heat. The heating element was permanently attached to the license plate heating as a heating coil on the outer edge of the license plate and on the rearview mirror in the form of light bulbs inside the mirror.
Im folgenden sind zwei Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben: Abb. I zeigt das Vorderteil eines Scheinwerfers von der Seite im Schnitt, Abb. 2 dasselbe Teil von oben im Schnitt, Abb. 3 einen Dreieckrückstrahler von vorn mit angebrachter Heizeinrichtung, Abb. 4 denselben Rückstrahler von oben, in Linie A-B nach Abb. 3 geschnitten, die Heizeinrichtung in Ansicht.The following are two embodiments of the invention with reference described in more detail on the drawings: Fig. I shows the front part of a headlight from the side in section, Fig. 2 the same part from above in section, Fig. 3 a Triangular reflector from the front with attached heating device, Fig. 4 the same Reflector from above, cut in line A-B according to Fig. 3, the heating device in view.
Die Lichtdurchlaßscheibe a bildet mit der gleich großen Lichtdurchlaßscheibe c einen abgeschlossenen Raum, in dem sich der elektrische Heizkörper b, der mit einer Kontaktstelle d an die Masse des Fahrzeuges, also dem Minuspol der Stromquelle, der anderen Kontaktstelle e mit dem zugehörigen Schaltkontakt des zugeordneten Leuchtsystems, also dem Pluspol der Stromquelle angeschlossen ist, befindet.The light transmission disk a forms with the light transmission disk c of the same size a closed space in which the electric heater b, with one contact point d to the ground of the vehicle, i.e. the negative pole of the power source, the other contact point e with the associated switching contact of the associated lighting system , i.e. connected to the positive pole of the power source.
Nach Abb. I und 2 wird die Lichtdurchlaßscheibe c mit dem auf ihr angebrachten Heizkörper b einfach zwischen der Lichtdurchlaßscheibe a und dem rückwärtigen Teil des Scheinwerfers eingelegt. Die beiden Lichtdurchlaßscheiben a und c bilden gemeinsam einen kleineren abgeschlossenen Raum. Dagegen wird in Abb. 3 und 4. die Lichtdurchlaßscheibe c mit dem auf ihr angebrachten Heizkörper b mit Hilfe einer entsprechenden Distanz haltenden Umrahmung h mittels Klammern f von von auf den Rückstrahler aufgesetzt. Es können natürlich auch andere Befestigungsmöglichkeiten an Stelle der Klammern f verwendet werden, z. B. Schraubverbindungen.According to Fig. I and 2, the light transmission disk c with the one on it attached radiator b simply between the light transmission panel a and the rear Part of the headlight inserted. Form the two light transmission disks a and c together a smaller closed room. In contrast, in Fig. 3 and 4. the Light transmission disk c with the radiator b attached to it with the help of a corresponding spacing frame h by means of brackets f from from to Reflector attached. Of course, other mounting options can also be used can be used in place of the brackets f, e.g. B. screw connections.
Wird nun der jeweilige Beleuchtungsstrom eingeschaltet, nachdem die Kontaktstellen d und e entsprechend angeschlossen wurden, so werden zugleich die zugehörigen Heizkörper b unter Strom gesetzt, so daß die Lichtdurchlaßscheibe a erwärmt wird und somit Schnee und Eis sich nicht ansetzen kann.If the respective lighting current is switched on after the If contact points d and e were connected accordingly, the associated heater b energized so that the light transmission disk a is heated so that snow and ice cannot accumulate.
