Tokyo Shj.be .ura KLectjfto Co. Lt ^ _n Kawasaki-fhi. Jatyan Title: Flash lamp

The present invention is concerned with a flashlight lamp, which is used for successive flashes is designed.

In recent years there are various flash devices developed with a successive lightning strike, in which a number of flash lamps or flash bulbs are inserted into a flash lamp holder and be healed one after the other. The flashlight lamps or light bulbs of this type consist of a transparent glass bulb, a luminous substance and a combustion-promoting gas, which are hermetically enclosed in this glass bulb, of a filament housed in this glass bulb and of two connecting wires that hold the filament and supply the electric current.

The successive flashing can for example thereby be accomplished, from outside the flashlight lamp or the flashlight bulb, that the Singangsklemmen several flash lamps or flash bulbs mechanically be switched. The successive flashing can also be done by electrical »switching, also this from outside the flashlight lamp or the flashlight bulb. As for the first run, it is not only a co'nplied construction required, it is then in addition, also prone to poor contact, which is in when the lamps or bulbs are not lit.

A »device according to the last-mentioned method is expensive and not very durable» it is also not sufficient for a positive one Flash photography because of bad contacts Ignition errors can arise.

In addition to the mechanical and electrical maintenance of the contacts a lightning device is known in which thermal switches for; a «series of» flash lamps or flash bulbs connected in parallel are provided and automatically getting closed. -

The connecting wires of two neighboring flashlights or Flashlight bulbs are arranged outside the flashlight lamps or flashlight bulbs opposite each other and between A chemical substance is introduced into these connecting wires, which are arranged opposite one another.

This chemical substance is usually an insulator, which is used but then as a good electrical conductor if it reacts or at elevated temperatures during the time of lightning is able to perform thermal expansion or thermal contraction with it at elevated temperatures the connecting wires if they are during the time of the flashing be heated, be short-circuited *

In addition, there are terhm switches for flash lamps or Flash bulbs for mass production sis not suitable because it requires additional material and operations.

The flashlight lamp or flashlight bulb falling within the scope of the present invention includes a transparent glass bulb and a holder of 2.0 cc or less, a light bulb and a combustion-promoting material or gas, which are also included in the glass bulb, the aforementioned combustion-promoting gas has up to 130 parts by weight of a high equivalent, which is necessary for the combustion of the material. This blichtlichtlarepe or blitittofet bulb also includes: two main connecting wires "with a" tube from 0.2 to 0.6 m, one of which extends into the interior of the glass bulb, an additional anaohln0dr "lit or a KLIf" on "connecting wire, which essentially the Durchneseer same has and along one of the ready-mentioned main terminal · »wires is guided in the interior of the glass bulb. the distance ⁽ⁱ aid between the lead wire and the one of the main ansohluQ-dröhte it is 75 percent or less of Hauptanschlißdrahtdiirchmessere.

During operation, a series of flashlight lasers or flashing light bulbs switched in a predetermined manner and actuated one after the other without going outside the Mechanical or electrical switches located in the glass bulb is resorted to.

Let us now explain the nominal proportion of the combustion-promoting gas, which is 100 to 130 parts by weight of an equivalent required for combustion or ignition of the luminous material. Because the heat generated when the luminous material is burned or ignited is not great enough to melt and short-circuit the first "secondary connection wire 16" and the auxiliary connection wire 1 ", the two wires 6 and 1 must be completely disconnected and short-circuited The experiment has shown that 100 percent or more parts by weight of the chemical equivalent are required to burn part of the wire as well.
