Abstract

La présente invention divulgue un barillet de lentille, comprenant un corps de barillet de lentille et un élément de blocage de lumière. L'élément de blocage de lumière et le corps de barillet de lentille sont des structures séparées, et l'élément de blocage de lumière est fixé au niveau d'un trou d'entrée de lumière du corps de barillet de lentille. L'élément de blocage de lumière comprend une partie de blocage de lumière. La partie de blocage de lumière est annulaire et située dans le trou d'entrée de lumière, et entoure et définit un trou de blocage de lumière. Le diamètre du trou de blocage de lumière est inférieur au diamètre interne minimal du trou d'entrée de lumière, et sert de diamètre d'ouverture du barillet de lentille. Dans la présente invention, l'élément de blocage de lumière ayant le trou de blocage de lumière est disposé au niveau du trou d'entrée de lumière, de façon à décaler l'emplacement au niveau duquel l'ouverture est conçue à partir du corps de barillet de lentille vers l'élément de blocage de lumière, ce qui permet de résoudre le problème selon lequel une matière plastique au niveau d'une ouverture est trop mince et entraîne donc une difficulté de moulage pendant le moulage par injection de plastique de barillet de lentille. La présente invention concerne en outre une lentille et un moule de fabrication de barillet de lentille.
