Title (EN) ENDOSCOPE LIGHT SOURCE DEVICE
(FR) DISPOSITIF SOURCE DE LUMIÈRE D'ENDOSCOPE
(JA) 内視鏡光源装置
Abstract:
(EN) The purpose of the present invention is to suppress variation in color balance of light beams emitted from distal ends of scopes even when scopes having different light guide diameters are combined. Provided is an endoscope light source device (10), comprising: a plurality of solid-state light sources (1, 2); a plurality of collimator lenses (11) for converting light beams emitted from the solid-state light sources (1, 2) into substantially parallel light beams; a multiplexing optical member (4) for multiplexing the substantially parallel light beams obtained by conversion by the collimator lenses (11); a light amount adjustment mechanism (5) disposed between at least one of the solid-state light sources (1, 2) and at least one of the collimator lens (11) and capable of adjusting a peripheral light amount from each of the solid-state light sources (1, 2); and a condensing lens (7) for condensing the light beams from the solid-state light sources (1, 2) multiplexed by the multiplexing optical member (4) to cause the light beams to enter the end surface of a light guide (8) of an endoscope.
(FR) L'objectif de la présente invention est de supprimer la variation de l'équilibre des couleurs de faisceaux lumineux émis par les extrémités distales d'endoscopes même lorsque des endoscopes ayant des diamètres de guidage de lumière différents sont combinés. L'invention concerne un dispositif source de lumière d'endoscope (10), comprenant : une pluralité de sources de lumière à semi-conducteurs (1, 2) ; une pluralité de lentilles de collimation (11) pour convertir des faisceaux lumineux émis à partir des sources de lumière à semi-conducteurs (1, 2) en faisceaux lumineux sensiblement parallèles ; un élément optique de multiplexage (4) pour multiplexer les faisceaux lumineux sensiblement parallèles obtenus par conversion par les lentilles de collimation (11) ; un mécanisme de réglage de quantité de lumière (5) disposé entre au moins l'une des sources de lumière à semi-conducteurs (1, 2) et au moins l'une des lentilles de collimation (11) et apte à régler une quantité de lumière périphérique à partir de chacune des sources de lumière à semi-conducteurs (1, 2) ; et une lentille de condensation (7) pour condenser les faisceaux lumineux provenant des sources de lumière à semi-conducteurs (1, 2) multiplexés par l'élément optique de multiplexage (4) pour amener les faisceaux lumineux à entrer dans la surface d'extrémité d'un guide de lumière (8) d'un endoscope.
(JA) ライトガイド径が異なるスコープを組み合わせてもスコープの先端から射出される光のカラーバランスの変動を抑える。複数の固体光源(1,2)と、各固体光源(1,2)から射出された光をそれぞれ略平行光にする複数のコリメートレンズ(11)と、各コリメートレンズ(11)により略平行光にされた光を合波する合波光学部材(4)と、少なくとも1つの固体光源(1,2)とコリメートレンズ(11)との間に配置され、各固体光源(1,2)からの周辺光量を調節可能な光量調節機構(5)と、合波光学部材(4)により合波された各固体光源(1,2)からの光を集光して内視鏡のライトガイド(8)の端面に入射させる集光レンズ(7)とを備える内視鏡光源装置(10)を提供する。
