Description
Claims (2)
- 金属製支持部材に支持された発光ダイオード(以下、「LED」という)ユニットを有する車輌用灯具であって、
前記LEDユニットは、LEDを支持したLED支持部と、前記LEDに対向した面が反射面とされたリフレクタと、該リフレクタの背面から突出したリブと、前記金属製支持部材に連結される連結部とがアルミダイカスト製品として一体に形成されて成り、
前記LED支持部はLEDを実装したLED基板をLEDの光軸が当該LEDユニットの出射光軸と垂直となる向きで支持すると共にLED基板の背面と面接触する載置面を有し、
前記リフレクタの反射面は、LEDの照射方向前方を覆うと共にLEDからの光を当該LEDユニットの前方へ向けて反射するように構成され、
前記連結部は、前記リフレクタの後側においてほぼ鉛直方向に伸びて位置すると共に前記金属製支持部材と接触する接触面を有し、
前記リブは複数あって、前記リフレクタの背面と前記連結部との間を連結している
ことを特徴とする車輌用灯具。 - 前記リフレクタの反射面は焦線がほぼ水平方向に延びる放物柱状面を為し、
前記LED支持部には複数のLEDが前記焦線の延びる方向に沿って列状に配列されている
ことを特徴とする請求項1に記載の車輌用灯具。
