Description
本発明は、新規な意匠を表現することができる車両用灯具を提供することを目的とする。
前方にアウターカバーを有する車両用灯具であって、
前記アウターカバーの灯具後方に設けられた、透光性を有する面状発光部を備える第1光源部と、前記第1光源部よりも灯具後方に設けられた第2光源部と、前記第1光源部よりも灯具後方に設けられた反射面と、を備え、
前記面状発光部の背面にハーフ蒸着面が形成されており、
前記反射面は、前記第1光源部から離間して設けられており、前記第2光源部から出射されて前記ハーフ蒸着面で一部反射された光を前記ハーフ蒸着面に向けて反射する。
前記アウターカバーは車両用ウィンドウ部材の一部を構成していてもよい。
前記面状発光部は透光性を有するOLEDであってもよい。
前記ハーフ蒸着面は前記OLEDの陰極の少なくとも一部を構成してもよい。
前記面状発光部は複数のLED素子が設置された透光性を有するFPCであってもよい。
前記第1光源部は前記面状発光部の端部に光を出射する光源を備え、
前記面状発光部は前記光源からの光を導光する導光部材であってもよい。
前記導光部材は拡散材を含有していてもよい。
前記面状発光部は前記アウターカバーに密着していてもよい。
続いて、図6を参照して、本実施形態の第1の変形例について説明する。第1の変形例と上述の実施形態とでは、第1光源部の構成が異なっている。図6は第1の変形例に係る第1光源部140、第2光源部60および反射面70を示す図である。図6の(a)は、第1光源部140及び第2光源部60の非発光時の様子を表す図であり、図6の(b)は、第1光源部140のみ発光している様子を表す図であり、図6の(c)は、第2光源部60のみ発光している様子を表す図である。第2光源部60および反射面70は上記の実施形態で説明したものと同様であるため、説明を省略する。
続いて、図7を参照して、本実施形態の第2の変形例について説明する。第2の変形例と上述の実施形態とでは、第1光源部の構成が異なっている。図7は第2の変形例に係る第1光源部240、第2光源部60および反射面70を示す図である。第2光源部60および反射面70は上記の実施形態で説明したものと同様であるため、説明を省略する。また、図7に示される導光部9は第1の変形例で説明したものと同様であるため説明を省略する。
続いて、図8を参照して、本実施形態の第3の変形例について説明する。第3の変形例と上述の実施形態とでは、第1光源部の構成が異なっている。図8は第3の変形例に係る第1光源部340、第2光源部60および反射面70を示す図である。第2光源部60および反射面70は上記の実施形態で説明したものと同様であるため、説明を省略する。また、図8に示される導光部9は第1の変形例で説明したものと同様であるため説明を省略する。
