Title (EN) ENDOSCOPE LIGHT SOURCE DEVICE
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE D'ENDOSCOPE
(JA) 内視鏡用光源装置
Abstract:
(EN) In the present invention, R, G, and B drive currents, which cause R_LD 27R, G_LD 27G, and B_LD 27B to emit light, control R, G, and B laser lights of the R_LD 27R, G_LD 27G, and B_LD 27B such that each R, G, and B laser light of the R_LD 27R, G_LD 27G, and B_LD 27B is split, through splitters 31R, 31G, 31B, into monitoring laser light and illuminating laser light that is emitted toward a scanning endoscope, and such that the quantity of the split monitoring laser light has a light quantity of monitoring light value that reflects the value of a split ratio when the temperature has changed. Thus, the quantity of the illuminating laser light is maintained within a range that meets predetermined conditions.
(FR) Dans la présente invention, des courants d'entraînement R, V et B, qui amènent R_LD 27R, G_LD 27G et B_LD 27B à émettre une lumière, commandent des lumières laser R, V et B de R_LD 27R, G_LD 27G et B_LD 27B de telle sorte que chaque lumière laser R, V et B de R_LD 27R, G_LD 27G et B_LD 27B est séparée, par l'intermédiaire de séparateurs 31R, 31G, 31B, en lumière laser de surveillance et en lumière laser d'éclairage qui est émise vers un endoscope de balayage, et de telle sorte que la quantité de lumière laser de surveillance séparée présente une quantité de lumière de valeur de lumière de surveillance qui réfléchit la valeur d'un rapport de séparation lorsque la température a changé. Ainsi, la quantité de lumière laser d'éclairage est maintenue dans une plage qui satisfait des conditions prédéterminées.
(JA) R_LD27R,G_LD27G,B_LD27BのR,G,Bレーザ光は、分波器31R,31G,31Bを経て監視レーザ光と、走査型内視鏡側に照射される照射レーザ光とに分岐し、分岐した監視レーザ光の光量が、温度が変化した場合の分岐比の値を反映した監視光光量値となるように、R_LD27R,G_LD27G,B_LD27Bを発光させるR,G,B駆動電流により制御することにより、照射レーザ光の光量を所定の条件を満たす範囲内にする。
