PROBLEM TO BE SOLVED: To provide a light source device for an endoscope capable of accurately estimating the life of a light source even when there are individual differences in light sources.SOLUTION: An endoscope device includes a light source for emitting illumination light, temperature measuring means for measuring a temperature that changes depending on an amount of light of the illumination light emitted from the light source, and light source life estimating means for estimating the life of the light source based on a temperature measured by the temperature measuring means. The endoscope device also includes an opening member that transmits part of the illumination light emitted from the light source, and the temperature measuring means measures a temperature of the opening member.COPYRIGHT: (C)2015,JPO&INPIT【課題】光源に個体差がある場合でも、光源の寿命を正確に推定することが可能な内視鏡用光源装置を提供する。【解決手段】内視鏡装置は、照明光を出射する光源と、光源から出射した照明光の光量に応じて変化する温度を測定する温度測定手段と、温度測定手段が測定した温度に基づいて、光源の寿命を推定する光源寿命推定手段と、を備えることを特徴とする。また、光源から出射した照明光の一部を透過させる開口部材を更に備え、温度測定手段は、開口部材の温度を測定する。【選択図】図1
