Claims (8)
- 少なくとも1個のLEDを有する光源と、当該光源から受光する光の送出部と、前記光源からの前記光のうちの前記光の送出部を通過する部分を反射すると共に当該部分を照明器具の前面に出射させる反射器と、を少なくとも有する、自動車用照明器具であって、反射部及び屈折部が前記光の送出部内に設けられ、前記反射部は、前記光源から発された光を、前記反射器の光軸と実質的に直角をなす一つの方向に、全反射にて屈折させ、前記屈折部は、前記光を、前記反射器の方向へと出射させ、前記自動車用照明器具は、少なくとも二つの機能をもち、第1の機能は、前記反射器を出てゆく前記光によって特徴づけられ、第2の機能は、前記反射器に入射しない前記光によって特徴づけられており、前記光源からの前記光の一部が、前記光の送出部から、規定された態様で発し、前記反射器には当たらない、自動車用照明器具。
- 前記光のうちの、前記光源から発し、規定された態様で前記光の送出部を通過する部分が、光導波路システムへと入射され得ることを特徴とする、請求項1に記載の自動車用照明器具。
- 前記光の送出部は、前記発した光が前記反射器へ入射する、少なくとも一つの光の放射面をもつことを特徴とする、請求項1に記載の自動車用照明器具。
- 前記光の送出部は、前記発した光が前記反射器に入射しない、少なくとも一つの光の放射面をもつことを特徴とする、請求項1に記載の自動車用照明器具。
- 前記反射器へ入射せず、及び/又は当該反射器へと導かれる、前記光の少なくとも一部が、前記照明器具の第2の機能を実施するのに役立つ光導波路へと入射されることを特徴とする、請求項1に記載の自動車用照明器具。
- 前記反射器は、中心が前記光軸上にはない少なくとも二つの部分から成ることを特徴とする、請求項1に記載の自動車用照明器具。
- 前記光源が、単一のLED光源であることを特徴とする、請求項1に記載の自動車用照明器具。
- 前記光源から規定された態様で前記光の送出部を通過し、前記反射器に入射することはない前記光の一部が、 実質的に完全に、光学部品、特に光導波路システムに指向性をもって入射され得ることを特徴とする、請求項1に記載の自動車用照明器具。
