    Abstract: A light guide emits lights incident on an end face from an emitting face extending longitudinally of the guide, while having the lights reflected by its internal face. A sectional shape of the guide in a direction orthogonal to the longitudinal direction of this light guide has two opposite parabolas, a line segment connecting the focal points of the two opposite parabolas, and a line segment (bottom face) corresponding to the emitting face. A scattering pattern consisting of white ink is formed on the line segment (bottom face) connecting the focal points. With this guide, the face of a document is to be efficiently illuminated by conversely utilizing the characteristic of the compound parabolic concentrator (CPC) to convert scattered lights extending over a full angle from a limited area into radiant lights confined to a prescribed emission angle and thereby minimizing the expansion of lights.

    Abstract:   【課題】      発光素子基板枠材の開口窓形状によらず効率良い発光が可能な発光ユニット、それを用いた照明装置、イメージセンサおよび画像読取装置を提供する。 【解決手段】  発光ユニットは、発光素子と、前記発光素子を搭載した発光素子基板と、前記発光素子を露出するための開口窓を有する発光素子基板枠材とを有し、前記開口窓内部は第１の樹脂および第２の樹脂で封止され、前記発光窓内部から発光窓外部に向かって、前記第1の樹脂に対する前記第２の樹脂の比率が小さくなっている。前記第１の樹脂は透明樹脂であり、前記第２の樹脂は明度の高い有色樹脂または、光反射および／または散乱材を含む樹脂である。前記第１の樹脂と前記第２の樹脂との断面境界線は、曲線となっているため、発光素子から出射された光のうち、開口窓底面で反射した光も効率良く外部に出射することができる。

    Abstract: A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.

    Abstract: There is disclosed a light guide for guiding light from a light source in a longitudinal direction and radiating the light to illuminate an object to be illuminated, which comprises a diffuser for diffusing the light from the light source along the longitudinal direction of the light guide, and a radiator for radiating the light diffused by the diffuser in a predetermined direction. By arranging the diffuser and the radiator so that a normal line passing through the center of the width of the diffuser is different from the predetermined direction at least in the vicinity of the light source when viewed in the longitudinal direction of the light guide, the illuminance distribution of the longitudinal direction of the light guide is uniformed.
