Abstract
Description
Claims (7)
- 光源と、前記光源からの光を導いて出射させる導光体と、を備え、
前記導光体は、導いた光を外部に出射させる出射面と、入射された前記光源からの光を前記出射面へ向けて反射する反射面と、を有し、
前記出射面は、前記反射面で反射されることにより直接導かれた光を出射させる第1出射箇所と、前記第1出射箇所と同一平面上に拡大された面で構成される第2出射箇所と、を有することを特徴とする車両用灯具。 - 前記導光体は、前記光源と対向しつつ前記光源の光軸と交差する方向に延びる奥壁部と、前記奥壁部から前記光軸の前側に立ち上がる側壁部と、を有し、
前記反射面は、前記側壁部において前記奥壁部に連続される側壁基部に設けられ、
前記出射面は、前記側壁部において立ち上がった先端の端面と、その立ち上がる途中に設けられた少なくとも1つの段部と、のそれぞれに設けられ、
前記第1出射箇所は、全ての前記出射面に設けられ、
前記第2出射箇所は、少なくとも1つの前記出射面に設けられていることを特徴とする請求項1に記載の車両用灯具。 - 前記側壁部には、厚みを低減する凹所が設けられ、
前記側壁部は、前記凹所を経ることで前記側壁部の外部を通って前記反射面から前記出射面に至る外部光路と、前記側壁部の内部を通って前記反射面から前記出射面に至る内部光路と、が形成されていることを特徴とする請求項2に記載の車両用灯具。 - 前記反射面は、前記内部光路に対応する第1反射面と、前記外部光路に対応する第2反射面と、を有することを特徴とする請求項3に記載の車両用灯具。
- 前記側壁部は、前記奥壁部を取り囲んで設けられており、
前記各出射面は、前記奥壁部を取り囲む複数の独立した環状とされていることを特徴とする請求項2から請求項4までのいずれか1項に記載の車両用灯具。 - 前記光源は、前記奥壁部の中央に対向して設けられ、
前記側壁部は、前記側壁基部側よりも立ち上がった先端側の方が前記光軸から離れるように傾斜されていることを特徴とする請求項5に記載の車両用灯具。 - 前記第2出射箇所は、前記第1出射箇所よりも前記光軸に近い側に設けられていることを特徴とする請求項5または請求項6に記載の車両用灯具。
