Claims (1)

Die Erfindung betrifft eine neue Form der durch Anspruch l des Stammpatentes geschützten Anordnung, da13 die Blende eingeschaltet werden kann, wenn der Hilfsspiegel ausgeschaltet ist. The invention relates to a new form of the arrangement protected by claim 1 of the parent patent, since the diaphragm can be switched on when the auxiliary mirror is switched off. Man mag den Strahlenkegel. dem die Blende in ihrer Einschaltstellung den Weg zum EMI1.1 Vorteil vor dem Gegenstand des Anspruchs 3 des Stammpatentes. bei dem der Hilfsspiegel als Blende verwendet wird und in der Blendenstellung seine Spiegelfläche der Lichtquelle zukehrt. You like the cone of rays. which the aperture in its on position the way to EMI1.1 Advantage over the subject matter of claim 3 of the parent patent. in which the auxiliary mirror is used as a diaphragm and in the diaphragm position its mirror surface faces the light source. Die Anordnung nach jenem Anspruch 3 gestattet zwar, dem Hilfsspiegel in seiner Blendenstellung einen grösseren oder kleineren Abstand von der Lichtquelle zu geben (im Ausführungsbeispiel [Fig. 3 bis 5] des Stammpatentes ist dieser Abstand gleich dem in der Hauptstellung) und dadurch dem zurückgeworfenen Strahlenkegel wenigstens angenähert den gewünschten Offnungswinkel zu verleihen, vorausgesetzt, dass ein Hohlspiegel und nicht ein ebener Spiegel als Hilfsspiegel gewählt ist. Über die Lichtverteilung in dem vom Blenden- Spiegel zurückgeworfenen Strahlenkegel vermag man aber nur dann einigermassen zu ver- fügen. wenn man als Blendenspiegel einen besonderen Spiegel anwendet wie in vorliegender AnordnungdesneuenSpiegelscheinwerfers. The arrangement according to that claim 3 allows the auxiliary mirror in its diaphragm position to be given a greater or smaller distance from the light source (in the embodiment [Fig. 3 to 5] of the parent patent, this distance is equal to that in the main position) and thereby the reflected beam cone to give at least approximately the desired opening angle, provided that a concave mirror and not a flat mirror is selected as the auxiliary mirror. The light distribution in the beam cone reflected by the diaphragm mirror can only then be made available to some extent. if a special mirror is used as a diaphragm mirror as in the present arrangement of the new mirror headlight. Ein Ausinhrunsbeispiel dieser Anordnung mit als Hohlspiegel ausgebildeter Blende ist in der Figur dargestellt. Der Hilfsspiegel et und der Blendenspiegel c sitzen auf einer Achse d, die in der Trommel b0 des Hauptspiegels b gelagert ist und im gezeichneten Beispiel die EMI1.2 spiegel c ausgeschaltet. Die punktierten Linien zeigen die Ausschaltstellung des Hilfsspiegels a und die Einschaltstellung dea Blendenapiegels c. An embodiment of this arrangement with a diaphragm designed as a concave mirror is shown in the figure. The auxiliary mirror et and the diaphragm mirror c sit on an axis d, which is mounted in the drum b0 of the main mirror b and in the example shown the EMI1.2 mirror c switched off. The dotted lines show the switch-off position of the auxiliary mirror a and the switch-on position of the diaphragm mirror c.
