There are those for electrically ignited flash lamps

The invention relates to a mechanically ignitable lamp holder which has already been received in practice Flash lamp, consisting of a light leadthrough, has come under the designation »flash cube casual vessel that holds a fuel, e.g. 3.

When assembling the well-known flashlight, it is not necessary to use lamps that have the nsaizfonf in the It is necessary that a relatively narrow center of the lamp vessel axis protrudes, Satchel prescribed position to the ignition mechanism- Fig. 6 schematically shows a bottom view of a lightning bolt is adhered to. throw ice with lamps in which the extension pipe against

When the soft metal tube 3 is tightly inserted, the lamp needs a small position, the ignition charge only has a smaller diameter than the lamp in the space between the wire and the inner vessel 2. The tube 3 is close to his upper wall of the approach to be filled, and the end 4 with the lamp vessel 3 in connection, mechanical shock when igniting can be closed from any but at the lower end S. Strike the glass direction, since practically every deformation 'vessel is tightly closed on the suction tube 6 of the attachment tube to squeeze the ignition and contains a suitable amount of fuel, set between the inner wall of the attachment tube 65 for example ZifkorMöüenspäiie 1, and one filling and d “A wire leads through which ignition from a combustion-promoting gas, for example, is initiated. wise oxygen, under high pressure from usual

A mechanically ignited primer 8 is housed in the tube 3, along its axis a hard metal wire 9, for example made of tungsten, is arranged. This wire serves as an anvil against which the Ignition charge is pushed when the tube 3 by an externally acting force, for example from a Firing pin being squeezed together. The wire 9 preferably protrudes into the film chips 7, and also serves to prevent the impact-sensitive mixture insert into the pipe by the wire
