Abstract

Anordning for tenning av et pyroteknisk materiale innbefattende elektroniske svitsjorgan (34, 36) for trigging av tenningen til det pyrotekniske materialet (42) som reaksjon på et signal. En laseriruiretning (38) er elektrisk forbundet med den elektroniske svitsjinnretningen for å generere en laserpuls som reaksjon på den elektroniske svitsjinnretningen. En optisk fiber (40) med en ende optisk koblet til laseriruiretningen (38) og den andre enden innleiret i det pyrotekniske materialet (42) slik at laserpulsen konsentrerer varme i den innleirede enden av den optiske fiberen og tenner det pyrotekniske materialet (42).Apparatus for igniting a pyrotechnic material including electronic switching means (34, 36) for triggering the ignition of the pyrotechnic material (42) in response to a signal. A laser irrigation direction (38) is electrically connected to the electronic switching device to generate a laser pulse in response to the electronic switching device. An optical fiber (40) having one end optically coupled to the laser irradiation direction (38) and the other end embedded in the pyrotechnic material (42) so that the laser pulse concentrates heat at the embedded end of the optical fiber and ignites the pyrotechnic material (42).
