Description
Elektrische Taschenlampe als Dunkelkammerlampe. Gegenstand der Erfindung ist eine elektrische Handdunkelkammerlampe. Solche Lampen mit verschiedenfarbigen Leuchtbirnen sind bekannt, bei denen durch Schaltung die einzelnen Birnen zum Leuchten und zum Verlöschen gebracht werden.Electric flashlight as a darkroom lamp. Subject of the invention is an electric handheld darkroom lamp. Such lamps with different colored Light bulbs are known in which the individual bulbs are switched on to light up and made to be extinguished.
Die Lampe nach der Erfindung hat nur eine Glühbirne und Filterrahmen, durch deren Verschiebung die Änderung der Lichtfarbe herbeigeführt wird.The lamp according to the invention has only a light bulb and filter frame, the change in the light color is brought about by shifting them.
In Abb. i ist a, a das Lampengehäuse und trägt im Innern eine Trockenbatterie. bl-, b2 sind rote und gelbe Farbfilter aus Glas. cl, e2 ist ein schmaler Metallstreifen und ist bei el, e2 durch am Filterhalter A, A angebrachte Scharniere beweglich.In Fig. I, a, a is the lamp housing and has a dry cell battery inside. bl-, b2 are red and yellow color filters made of glass. cl, e2 is a narrow metal strip and at el, e2 can be moved by hinges attached to the filter holder A, A.
d', d2 stellt Hacken oder Nasen vor, welche in das Lampengehäuse einschnappen und den Schieber cl, C2 in der Ruhelage festhalten. f ist eine Zerstreuungslinse aus Glas, g ein Reflektor und trägt in der Mitte Glühlämpchen h.d ', d2 represents hooks or noses which snap into the lamp housing and hold the slider cl, C2 in the rest position. f is a diverging lens made of glass, g is a reflector and has a light bulb h in the middle.
i ist der Kontaktknopf, k die Batterie, 111 12 sind Kontaktfedern der Batterie, m ist die Verbindungskontaktfeder. Verbindung wird hergestellt durch Druck auf Knopf i, wodurch Feder m an Kontakt der Batterie gedrückt wird.i is the contact button, k is the battery, 111 12 are contact springs of the battery, m is the connecting contact spring. Connection is established by pressing button i, whereby spring m is pressed on the contact of the battery.
In Abb. _q ist die Lampe mit den Filtern von oben gesehen dargestellt.Fig. _Q shows the lamp with the filters seen from above.
bli b2 sind Rot- und Gelbfilter, Cl 3 C2 Schieber, el, e2 Scharniere des Schiebers, d', d2 Klemmhacken des Schiebers, g der Reflektor, h das Glühlämpchen, i, i das Auflageblech der Filter.bli b2 are red and yellow filters, Cl 3 C2 slider, el, e2 hinges of the slider, d ', d2 clamping hooks of the slider, g the reflector, h the light bulb, i, i the support plate of the filter.
Abb. 3 zeigt den Halter für die Farbfilter. Er besteht aus einem der Dicke der Farbfilter entsprechenden Metallstreifen und ist bei den Längssehenkeln A, A umgebogen. Dieser Halter umfaßt an den Schnittflächen der Filter diese und kann die Filter durch Verschieben jeweils vör die Lampe führen.Fig. 3 shows the holder for the color filters. It consists of a metal strip corresponding to the thickness of the color filter and is bent over at the longitudinal strings A, A. This holder covers the cut surfaces of the filters and can guide the filters in front of the lamp by moving them.
Bei Beginn der Entwicklurg kann man den an der roten Filterseite befindlichen Schieber c hochschlagen und das Filter über den Reflektor g vor die Lampe h schieben. Ist die Platte der Kassette entnommen und z. B. in den mit Safranin angefärbten Entwickler gelegt, wird das rote Filter zurückgezogen und an dessen Stelle das gelbe Filter geschoben. Mit diesem hellen gelben Lichte kann die Entwicklung zu Ende geführt werden. Das Wechseln der Filter geht sehr rasch vor sich.At the beginning of the development you can turn up the slide c on the red side of the filter and slide the filter over the reflector g in front of the lamp h. Is the plate removed from the cassette and z. B. placed in the developer stained with safranin, the red filter is withdrawn and the yellow filter is pushed in its place. With this bright yellow light, the development can be completed. Changing the filters is very quick.
Bei zurückgezogenen Filtern gibt die Lampe, wie" jede andere, weißes Licht, so daß mit dieser Lampe drei Lichtarten erzielbar sind.When the filters are withdrawn, the lamp emits, like "any other, white Light, so that three types of light can be achieved with this lamp.
