Abstract
Description
図1に示すように、車両10には、車両用灯具11が装着されている。この実施形態の車両用灯具11は、車両10の前方に装着された前照灯である。車両用灯具11は、車両10の左右両側に設けられており、対称構造である。左右に設けられた車両用灯具11のそれぞれは、同一の機能を備えている。なお、以下の説明は、左右の車両用灯具11のうち、車両10の右側(図中左側)に装着された車両用灯具11について行う。
第2光源16を点灯させた場合、第1〜第6発光ユニットY1〜Y6は発光する。これにより、上部発光部17aは、入射される第1,第2発光ユニットY1,Y2の光が第1導光体21で内部反射されることで線状に発光する。下部発光部17bは、入射される第3,第4発光ユニットY3,Y4の光が第2導光体23で内部反射されることによって線状に発光する。これにより、車両用灯具11は、車幅方向に沿う長さ方向に広範囲に亘って発光する。
(1)リフレクタ27を用いた光学系と第3導光体25を用いた光学系とを組み合わせて発光部を構成した。具体的に言えば、リフレクタ27の反射面26に重ねるように第3導光体25を配置した。これにより、リフレクタ27による光と第3導光体25による光とで車両10の前方及び側部の異なる方向から視認しても、車両用灯具11の点灯を確認することができ、配光性能に優れた車両用灯具11を構成することができる。
○ 実施形態におけるリフレクタを用いる光学系と導光体を用いる光学系の組み合わせは、デイタイムランニングランプやクリアランスランプとは異なる用途で用いてもよい。
○ 上部発光部17a、下部発光部17b及び側部発光部17cの具体的な意匠(形状など)は任意に変更してもよい。例えば、直線状に限らず、湾曲状、波状、あるいはジグザグ状としてもよい。また、上部発光部17aと下部発光部17bを同一意匠としてもよい。
○ 第1〜第6発光ユニットを構成する発光体は、チップLEDとしてもよいし、電球としてもよい。
Claims (3)
- 灯室内に複数の発光部を備えた車両用灯具であって、
発光体からの光を内部反射させて発光する導光体を有する第1発光部と、
発光体からの光を車両の前方に反射させるリフレクタを有する第2発光部と、を備え、
前記第1発光部の導光体は、前記車両の側部寄りに、かつ発光部分の少なくとも一部分が前記リフレクタで反射される光の経路に重なって配置されていることを特徴とする車両用灯具。 - 前記車両用灯具は、複数の第1発光部を備え、
前記複数の第1発光部には、
車両の側部に向けて発光するとともに車高方向に沿って線状に発光する側部発光部と、
車両の前方に向けて発光するとともに車幅方向に沿って線状に発光し、前記側部発光部よりも前記車高方向の上部に配置された上部発光部と、
車両の前方に向けて発光するとともに車幅方向に沿って線状に発光し、前記側部発光部よりも前記車高方向の下部に配置された下部発光部と、を含み、
前記側部発光部の導光体における発光部分の少なくとも一部分が前記リフレクタで反射される光の経路に重なって配置されている請求項1に記載の車両用灯具。 - 前記側部発光部の導光体と前記下部発光部の導光体とは一体化されており、
前記側部発光部の発光体の光は前記側部発光部の導光体を通じて前記下部発光部の導光体にも入射される請求項2に記載の車両用灯具。
