摘要： A light source device includes a light-condensing device that condenses an illumination light that is emitted from a light source lamp. The light-condensing device includes at least one lens, a lens holder in which a lens is fixedly provided, and a lens holding member. The lens holding member is a member for fixing a lens to the lens holder. The lens holding member causes at least one circumferential portion of the lens to protrude to the lens holder side, and causes the optical axis of the lens to match the optical axis of the illumination light.

摘要： A light source device includes a light source lamp, a rotary plate, a heat absorbing portion, and a filter mounting member. The light source lamp emits illumination light. The rotary plate includes multiple opening portions that are selectively disposed in the illumination light path of the light source lamp. A reflective filter that reflects light of a wavelength that acts a heat source in illumination light is provided in one of the multiple opening portions of the rotary plate. The heat absorbing portion absorbs heat included in reflected light reflected by the reflective filter in the opening portion. The filter mounting member disposes the reflective filter in the opening portion at a predetermined angle of inclination to the optical axis of the illumination light. By disposing the inclined reflective filter in the illumination light path, reflected light reflected by the reflective filter is reflected towards the heat absorbing portion.

摘要： 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.

摘要： 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.
