Claims (5)
- 光源からの出射光がリフレクタの反射面で反射されることで、素通しのインナーレンズ及び素通しのアウターレンズを透過して灯具前方に所定の主配光で照射する車両用灯具のインナーレンズであって、
前記インナーレンズは、該インナーレンズの本体部の前記反射面側の面の該反射面に対向する領域に複数の独立した凸状の突起部が設けられ、
前記突起部は、円錐体を該円錐体の軸に平行な面で切断した形状を呈しており、
前記円錐体の側面に対応する位置には、傾斜曲面が設けられており、
前記円錐体の底面に対応する位置には、円弧形状で形成された起立平面が設けられており、
前記光源から出射して前記インナーレンズの突起部に照射されて該突起部及び前記本体部を透過した光は、前記起立平面での反射及び、前記傾斜曲面での屈折によって、前記灯具の斜め前方方向に前記主配光の形成には寄与しない光として照射されることを特徴とする車両用灯具のインナーレンズ。 - 前記インナーレンズは、該インナーレンズの本体部の前記領域の面積に対する前記突起部の総占有面積の比率が5%以下であることを特徴とする請求項1に記載の車両用灯具のインナーレンズ。
- 前記突起部は、前記インナーレンズの本体部の中心軸に対して等角度で放射状に且つ同心円上に設けられていること特徴とする請求項1又は請求項2に記載の車両用灯具のインナーレンズ。
- 前記起立平面は半径0.8mm、幅1.5mmの円弧状を呈していることを特徴とする請求項1〜請求項3のいずれかに記載の車両用灯具のインナーレンズ。
- 前記突起部は全て、前記起立平面を前記インナーレンズの本体部の中心軸方向に向けて配置されていることを特徴とする請求項1〜請求項4のいずれかに記載の車両用灯具のインナーレンズ。
