  • Patent number: 8727575
    Abstract: A light source unit is equipped with a light source having a discharge lamp and a converging mirror, and a light guide formed of a liquid core fiber which is held by a light guide holding portion. The light source and the light guide are held in a casing made of a metal, and an infrared cut filter is provided in a cylindrical light shielding body surrounding an optical path in the interior of the casing. The light shielding body forms a stray light preventing member which prevents stray light from going out of the casing, and a light quantity adjusting member is provided between an opening of the light shielding body on a light guide side and a light incident port of the light guide. The light shielding body and the light guide holding portion are thermally insulated from each other by a heat insulating material portion.

  • Patent number: 8591085
    Abstract: An optical fiber light source apparatus, includes a casing, a discharge lamp accommodated inside the casing, a concave reflection mirror, which holds the discharge lamp, and an optical fiber, which receives light from the reflection mirror. The concave reflection mirror, to which the discharge lamp is fixed, is held by a holding member, which has an approximately rectangular flange portion in a front face thereof and a regulating concave portion formed in a side of the flange portion. A guide is provided on the casing in a direction perpendicular to an optical axis, so that the flange portion of the holding member is slidably engaged with the guide. A pressing member, which is pressed with a bias force toward the regulating concave portion of the flange and engages with the regulating concave portion, is provided on the guide, thereby securing the concave reflection mirror.

  • Patent number: 8044559
    Abstract: A discharge lamp of the short arc type has a bulb with an arc tube and sealing tubes extending at opposite sides of the arc tube and which contains a discharge gas and a pair of opposed electrodes supported on lead pins which protrude from the outer end of the sealing tubes, the lead pins being affixed to graded glass in the sealing tube. A cooling fin surrounds the outer surface of one of the sealing tubes; and is formed of a pair of plate-shaped bodies each of which has a curved portion that contacts an outer surface of the sealing tube a strip-shaped portion extending radially from each of opposite edges of the curved portion. The strip-shaped portions of the plate-shaped bodies positionally overlap, and cooling openings are formed in the strip-shaped portions of only one of the plate-shaped bodies. Preferably, a gap is formed between the plate-shaped bodies.
