发明名称 ILLUMINATION LIGHT GUIDE
摘要 PROBLEM TO BE SOLVED: To increase the amount of light distribution from an outgoing part by restricting light leakage from a flank of a transparent material.SOLUTION: A light guide 10 of a vehicular light fitting comprises: a first transparent material 11 that guides incident light from a stationary side light source 6A; and a second transparent material 21 that guides incident light from a movable side light source 6B. The first transparent material 11 is formed in a strip of arcuate twisted so as to become wider away from an incident part 12. A reflection part 35 is formed on rear faces of the first and second transparent materials 11 and 21 for reflecting incident light on the front side while an emission part 36 is formed on front faces for emitting reflection light. On lateral faces 33 and 34 of the transparent materials 11 and 21, curved surfaces are included which appear as contours on a cross section of the transparent material. On the first lateral face 33 of the first transparent material 11, a lateral face step 38 is formed for reflecting incident light toward the second lateral face 34 so as to dissolve a dark space inside the arcuate part.SELECTED DRAWING: Figure 2
