Abstract

L'invention porte sur un projecteur, qui comprend une source de lumière (3), un système de focalisation et un système de dissipation de chaleur. Le système de focalisation peut supporter une focalisation manuelle et une focalisation électrique. Une molette externe (14) est reliée à un engrenage (7) par l'intermédiaire d'un arbre d'engrenage (10), et une crémaillère (9) effectue une transmission de façon à coopérer avec l'engrenage (7). La distance à partir d'une lentille de Fresnel jusqu'à la source de lumière (3) est réglée par la rotation de la molette externe (14), de façon à réaliser une focalisation manuelle. Un engrenage (6) est relié à un moteur (12) par l'intermédiaire d'un arbre d'engrenage (11). Une molette de focalisation (16) sur un panneau de commande peut commander l'activation du moteur (12), de façon à réaliser une focalisation électrique. La plage de réglage de l'angle d'émission de lumière est entre 15 et 50 degrés. Le système de dissipation de chaleur comprend un pilier conduisant la chaleur (4) et un dissipateur de chaleur (5). Un ventilateur commandé en température (8) est commandé par une puce commandée en température, et peut maintenir la température interne à environ 60 degrés. Le projecteur est principalement utilisé dans des applications telles que pour des scènes, des salles de classe, etc.
