參閱圖6、7、8，該遮板7可被控制而相對於該透鏡4在一遮光位置與一遠離位置之間轉動。 Referring to FIGS. 6, 7, and 8, the shutter 7 can be controlled to rotate relative to the lens 4 between a light-shielding position and a remote position.

參閱圖5、7、9，在該遮光位置時，該遮板本體71的頂面713對應於該第二焦點54並向下延伸，該發光單元6所發出的光線部分經由該第一反射面511的反射後，通過該第二焦點54並由該入光面41進入該透鏡4，部分光線經由該第二反射面521的反射後，通過該第二焦點54並由該入光面41進入該透鏡4，該遮板7用以遮蔽部分通過該第二焦點54的光線並形成明暗截止線，其餘進入該透鏡4的光線則由該出光面42投射出一近燈光形。該凹槽715用來減少部分經由該複合反射單元5反射並經由該遮板本體71的頂面 713反射而向該入光面41投射的光線，避免歐規ECE R112之配光點50L過亮，可以降低直接投射至對向駕駛或間接經由潮濕路面反射之光線，亦即可有效減少影響對向來車的眩光。 5, 7, 9, in the shading position, the top surface 713 of the shutter body 71 corresponds to the second focal point 54 and extends downward, part of the light emitted by the light-emitting unit 6 through the first reflective surface After the reflection of 511, it passes through the second focal point 54 and enters the lens 4 from the light incident surface 41. After being reflected by the second reflecting surface 521, part of the light passes through the second focal point 54 and enters from the light incident surface 41. The lens 4 and the shutter 7 are used to shield part of the light passing through the second focal point 54 and form a cut-off line. The rest of the light entering the lens 4 is projected by the light exit surface 42 into a near-light shape. The groove 715 is used to reduce part of the reflection through the composite reflection unit 5 and through the top surface of the shutter body 71 The light reflected by 713 and projected to the light-incident surface 41 avoids the light distribution point 50L of the European standard ECE R112 from being too bright, which can reduce the light directly projected to the opposite driving or indirectly reflected by the wet road, which can effectively reduce the impact on The glare of oncoming cars.

參閱圖5、8、10，該遠離位置時，該遮板本體71的頂緣向後轉動而不通過該第二焦點54，該發光單元6所發出的光線部分經由該第一反射面511的反射後，通過第二焦點54並由該入光面41進入該透鏡4，部分光線經由該第二反射面521的反射後，通過第二焦點54並由該入光面41進入該透鏡4，前述光線再共同由該出光面42投射出一遠燈光形。值得注意的是，在本實施例中藉由一制動單元(圖未示)帶動該遮板7相對該基座2轉動，但該遮板7的控制方法並非本新型的重點，故不在此多做贅述。 5, 8, 10, when the far position, the top edge of the shutter body 71 rotates backward without passing through the second focal point 54, part of the light emitted by the light emitting unit 6 is reflected by the first reflective surface 511 Then, it passes through the second focal point 54 and enters the lens 4 from the light incident surface 41. After being reflected by the second reflecting surface 521, part of the light passes through the second focal point 54 and enters the lens 4 from the light incident surface 41. The light rays collectively project a far-light shape from the light-emitting surface 42. It is worth noting that in this embodiment, a brake unit (not shown) drives the shutter 7 to rotate relative to the base 2, but the control method of the shutter 7 is not the focus of the present invention, so it is not here. Do repeat.

進一步說明經由該第一反射面511反射的光線，較偏離該光軸A，形成一擴光區域C，經由該第二反射面521反射的光線，較集中在該光軸A附近，形成一聚光區域D，藉由該第一反射面511與該第二反射面521之間的落差設計，能夠有效提升該該第二反射面521的聚光效率，使本新型不須第二組發光源，即可達到遠光燈的亮度要求。 It is further explained that the light reflected by the first reflecting surface 511 is relatively deviated from the optical axis A to form a light diffusion area C, and the light reflected by the second reflecting surface 521 is more concentrated near the optical axis A, forming a condensing area. The light area D, through the design of the height difference between the first reflective surface 511 and the second reflective surface 521, can effectively improve the light-gathering efficiency of the second reflective surface 521, so that the present invention does not require a second set of light-emitting sources , It can meet the brightness requirements of high beam headlights.

在本實施例中，該第一反射面511與該第二反射面512之間的落差不小於0.1毫米，並能夠藉由調整前述反射面的位置、覆蓋範圍及曲面曲率，來控制光線反射的方向，增加應用上的彈性。 In this embodiment, the height difference between the first reflective surface 511 and the second reflective surface 512 is not less than 0.1 mm, and the position, coverage and curvature of the curved surface of the aforementioned reflective surface can be adjusted to control the light reflection. Direction to increase application flexibility.
