    • There is provided a line illuminating device in which a rod-shaped light guiding member is incorporated, the light guiding member producing substantially no color variation in the vicinity of the end on which light is incident. A light scattering pattern 20 for scattering incident light is integrally formed in a bottom surface 11b of a rod-shaped light guiding member 11. The light scattering pattern 20 is comprised of a large number of recesses 21. The recess 21 is shaped into a triangular groove with its longitudinal direction being the short-side direction of the light guiding member 11. Inclined surfaces 22, 22 that form the triangular groove have a large number of minute recesses 23 formed integrally therewith. Each of the minute recesses 23 is a triangular groove along the longitudinal direction of the recess 21.
    • 提供一种线照明装置,其中结合有杆状导光构件,导光构件在光入射端部附近基本上不产生颜色变化。 用于散射入射光的光散射图案20一体地形成在棒状导光构件11的底面11b中。光散射图案20由多个凹部21组成。凹部21成形为三角形 槽的纵向是导光构件11的短边方向。形成三角形槽的斜面22,22具有与其一体形成的大量微小凹部23。 每个微小凹部23是沿着凹部21的长度方向的三角形槽。
