Abstract

L'invention porte sur une lampe torche de zoom, laquelle lampe comprend un tube d'objectif (1). Le tube d'objectif (1) est relié à une diode électroluminescente (10), et une extrémité avant du tube d'objectif (1) est reliée à une bague de torsion (7). Une chambre de lentilles (31) est disposée à l'avant de la diode électroluminescente (10), et un ensemble de verre de focalisation de lumière est disposé à l'intérieur de celle-ci. Une chambre de lentilles arrière (12) est disposée à l'avant de la chambre de lentilles (31), et un premier groupe de lentilles de focalisation est fixé dans la chambre de lentilles arrière à l'aide d'une bague de pression de chambre de lentilles arrière (19). Une extrémité avant de la bague de torsion (7) est reliée à un capot externe (13). Un tube externe (14) est disposé à l'intérieur de la bague de torsion (7) et du capot externe (13), et un tube interne (15) est disposé dans le tube externe (14). Le tube externe (14) est relié à la bague de torsion (7) par une vis de réglage à multiplication de puissance (16). La chambre de lentilles arrière (12) est reliée au tube externe (14) et au tube interne (15) par une première vis à broche coulissante (17) et un premier manchon en Nylon (18). Les extrémités avant du tube externe (14) et du tube interne (15) sont reliées à une chambre de lentilles avant (22) par une seconde vis à broche coulissante (20) et un second manchon en Nylon (21). Un second groupe de lentilles de focalisation est fixé dans la chambre de lentilles avant (22) à l'aide d'une bague de pression de chambre de lentilles avant (32). Un verre protecteur (24) est disposé dans l'avant de la chambre de lentilles avant (22). L'objectif optique est utilisé pour régler l'anneau de lumière sans l'utilisation de la coupelle de lampe classique, de telle sorte que la lumière de l'anneau de lumière formé dans l'éclairage est régulière et qu'aucun halo n'est formé, cependant que la taille de l'anneau de lumière peut être réglée.
