  • Patent number: 8066409
    Abstract: 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.

  • Patent number: 7789532
    Abstract: 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.

  • Patent number: 7043156
    Abstract: A strobe apparatus includes a xenon tube, which is a discharge tube, having a discharge light emitting portion and a light emitting portion terminal. Light is emitted from the xenon tube and is reflected in a predetermined direction by a reflection umbrella. A transparent electrode is coated on the external surface of the xenon tube from the discharge light emitting portion to the terminal. When trigger voltage is applied to the xenon tube through the transparent electrode, strobe light is emitted by the discharge light emitting portion. By using the strobe apparatus, the orientation characteristic of the discharge tube can be improved without uneven light distribution and a shortage of a light amount.

  • Publication number: 20050135797
    Abstract: A camera having a camera-blur warning function which is adapted to switch between executing a camera-blur detecting mode and stopping the camera-blur detecting mode by the setting of a camera strobe mode. In a photographing scene where occurrence of a camera-blur is on a user's mind, a camera-blur detecting mode is set, thereby to detect vibration. In case any camera-blur occurs, warning is made so that the user may recognize it. Furthermore, at the time of determining holding, a conventional optical sensor which is already mounted as a sensor for measuring distance is utilized for determining the camera-blur.
