    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: 8684578
    Abstract: A lighting device (30) comprises a side-light light guide 1? located in a support (2) that has an elongate opening for the passage of light emitted by the light guide. The support (20) is shaped to provide contact edges (24) and the only physical engagement between the support and the light guide is along those contact edges. The support also has planar surfaces internal positioned adjacent, and parallel to, planar surfaces (15) in the light guide to retain the light guide in the required orientation in the support. To enhance the flexibility of the support, in some embodiments only part of the support is continuous along the whole length of the support (FIGS. 14 to 19).
