Abstract

La présente invention vise à fournir un module de source de lumière pour endoscope dont la structure est améliorée de manière à ce que le modèle de source de lumière pour endoscope soit monté dans un endoscope pour présenter un éclairage efficace. La présente invention concerne par conséquent un module de source de lumière qui est facile à monter et un éclairage efficace tout en empêchant un champ de vision peu clair d'un module de caméra et l'éblouissement dû à une source de lumière DEL.
