Abstract

L'INVENTION CONCERNE UN DISPOSITIF PERMETTANT D'OBTENIR UN RAYONNEMENT IR A PARTIR D'UNE TRES FAIBLE INTENSITE DE COURANT, OBTENANT AINSI UNE PORTEE UTILE TRES NETTEMENT ACCRUE. LE SYSTEME EST CONSTITUE DE LA PLATINE ELECTRONIQUE 1 ASSOCIEE A SON ALIMENTATION SECTEUR 2. L'ENSEMBLE D'EMISSION IR 3 CONSTITUE D'UN CORPS RIGIDE 3-3 DE LONGUEUR CALCULEE, D'UNE LENTILLE 3-2 A FORT GROSSISSEMENT EMET A PARTIR DES DIODES 3-1 DES RAYONS VERS L'ENSEMBLE RECEPTIF IR 4. CES RAYONS AU CONTACT DE LA LENTILLE 4-2 SONT CONCENTRES ET DIRIGES SUR LA DIODE DE RECEPTION IR 4-1. CETTE DIODE SE TROUVE EGALEMENT A UNE DISTANCE CALCULEE DE LA LENTILLE, DISTANCE MATERIALISEE PAR LES DIMENSIONS DU TUBE 4-3. EN CAS DE RUPTURE DU FAISCEAU, UN RELAIS 5 ACTIVE, VIA L'EDF, UN SYSTEME LUMINEUX ET (OU) UN SYSTEME SONORE.
