    • A light source device includes a light source, a diaphragm blade for adjusting light quantity of illumination light supplied from the light source, a diaphragm driving part for driving the diaphragm blade to perform opening/closing operation, and a diaphragm control circuit part for setting diaphragm drive instruction voltage to be supplied to the diaphragm driving part and control an opening/closing amount of the diaphragm blade. In the diaphragm control circuit part, a fully-opened voltage and a fully-closed voltage at the time the diaphragm blade is fixed at a fully-opened position and a fully-closed position are read, based on the voltages, adjustment data for adjusting the diaphragm drive instruction voltage and the opening/closing positions of the diaphragm blade is set, and based on the adjustment data, a control range of the diaphragm drive instruction voltage is regulated.
    • 光源装置包括光源,用于调节从光源供给的照明光的光量的光圈叶片,用于驱动光阑叶片进行打开/关闭操作的光阑驱动部,以及用于设定光阑的光阑控制电路部 驱动指令电压被提供给隔膜驱动部分并且控制光阑叶片的打开/关闭量。 在光阑控制电路部分中,基于电压读取在光阑叶片固定在完全打开位置和完全关闭位置时的完全打开的电压和全闭合电压,用于调节的调整数据 光阑驱动指令电压和光阑叶片的打开/关闭位置被设定,并且基于调节数据,调节光阑驱动指令电压的控制范围。

    • A light source apparatus capable of controlling a quantity of light in a stable manner and an endoscope apparatus including the light source apparatus are provided. The light source apparatus includes a light source and a light quantity adjusting portion for limiting the light flux from the light source using an aperture blade. The light quantity adjusting portion includes the aperture blade which is driven to rotate in a vertical plane about a pivot and has a center of gravity which is decentered from the pivot, a position detecting portion for detecting a position of the aperture blade, a driving portion, and a light source controlling portion for controlling the driving portion. The light source controlling portion controls the driving portion based on the position of the aperture blade and a rotation direction.
    • 提供一种能够稳定地控制光量的光源装置和包括该光源装置的内窥镜装置。 光源装置包括光源和光量调节部分,用于使用光圈叶片来限制来自光源的光通量。 所述光量调节部包括所述光圈叶片,所述光圈叶片被驱动以围绕枢轴的垂直平面旋转,并且具有从所述枢轴偏心的重心;位置检测部,用于检测所述光圈叶片的位置;驱动部 以及用于控制驱动部的光源控制部。 光源控制部基于光圈叶片的位置和旋转方向来控制驱动部。
