Abstract

L'invention concerne un allume-cigarette laser comprenant : une enveloppe (1) et un cylindre (2) d'allumage de cigarette agencé séparément à l'intérieur de l'enveloppe (1). Le cylindre (2) d'allumage de cigarette est muni d'une cavité destinée à recevoir une cigarette. Au moins un dispositif d'allumage laser est agencé sur la périphérie du cylindre (2) d'allumage de cigarette, le point laser produit par le dispositif d'allumage laser convergeant à l'intérieur de la cavité. Le briquet décrit utilise de multiples dispositifs d'allumage laser répartis autour du cylindre (2) d'allumage de cigarette. Lorsqu'une cigarette est introduite dans le cylindre (2) d'allumage de cigarette, de multiples points autour de l'avant et de l'arrière de la cigarette peuvent être allumés en même temps, augmentant ainsi l'efficacité d'allumage de la cigarette et diminuant la puissance laser requise en provenance d'un laser à semi-conducteur (3), améliorant l'efficacité de dissipation de la chaleur de l'enveloppe (1) et empêchant le réchauffement de l'enveloppe (1). L'allumage de la cigarette peut être effectué manuellement au moyen d'une pression exercée sur un bouton, ou automatiquement.
