<P>PROBLEM TO BE SOLVED: To provide a vehicular lamp fitting having an illumination or display function as well as being endowed with an additional value such as designability or decorativeness by visual production effects of light. <P>SOLUTION: In the vehicular lamp fitting using a light guide plate, a plurality of narrow directional characteristic LED light sources 10a and a plurality of wide directional characteristic LED light sources 10b are alternately arranged at a given interval with a light emission surface 25 headed to an end surface 21a side in the vicinity of that 21a of one end part 21 out of end parts of a light guide plate 20 facing each other, a notch part 23 opened in a V shape outwardly at a position on each optical axis (X<SB POS="POST">1</SB>) of each of the plurality of narrow directional characteristic LED light sources 10a of the other end part 22 facing to the one end part 21. Each of two notch surfaces 28 of the notch part 23 opened in a V shape is set to have an angle larger than a critical angle against reaching light emitted from the narrow directional characteristic LED light source 10a and guided inside the light guide plate 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
