Description
また、導光棒が車幅方向に沿って延び、導光棒の出射面が下方に向き、導光棒の外周面のうち出射面に相対する部位に複数の乱反射部が形成されているので、出射面から出射される光が車幅方向に沿って均一な光度分布となる。そのため、ライセンスプレートを幅方向にわたって均一な明るさで照明することができる。
本発明を適用可能な実施形態は、上述の実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。以下、変形例について説明する。
10 ハウジング
13 保持部
13a 保持穴
13c 位置決め切欠き
30 導光棒
31 入射面
32 全反射面
33 出射面
34 乱反射部
35 位置決め凸部
40 発光素子
99 ライセンスプレート
