Abstract

L'invention porte sur un système de focalisation de lumière à poussée et torsion pour une lampe flash, lequel système comprend un élément de focalisation mobile dans une direction longitudinale de la lampe flash ; une source de lumière ; une lentille de focalisation ; et un mécanisme de transformation de mouvement de rotation en mouvement longitudinal couplé de façon fonctionnelle à l'élément de focalisation et à au moins l'une de la source de lumière et de la lentille de focalisation de façon à transformer un mouvement longitudinal de l'élément de focalisation en un mouvement de rotation. Dans le mécanisme de transformation de mouvement de rotation en mouvement longitudinal, un mouvement longitudinal relatif entre la source de lumière et la lentille de focalisation permet d'obtenir une focalisation.
