Abstract

L'invention concerne un module de source de lumière pour un endoscope, comprenant : une puce DEL destinée à émettre une source de lumière vers l'avant, à l'aide d'électricité appliquée à travers une borne d'électrode ; et un bloc de résine présentant la puce DEL incorporée en son sein et une rainure pour fibre formée au niveau d'un côté de ce dernier à travers laquelle la source de lumière est émise, de sorte qu'une extrémité d'une fibre optique soit accouplée à la rainure pour fibre. La présente invention, telle que décrite ci-dessus, présente une structure dans laquelle une DEL et une fibre optique sont directement accouplées l'une à l'autre et pouvant ainsi réduire au minimum leur agencement. Ainsi, il est attendu que la présente invention puisse réduire non seulement le volume mais également le coût de fabrication.
