Description

照明装置及光学模块 技术领域
本发明涉及一种照明装置及光学模块，尤其涉及一种用于远近光灯的照明系统，具有近光灯的补光的照明装置及光学模块。
背景技术
在现有的投射式的照明装置下，当发光二极管(Light-emitting diode,LED)的光源相对紧密排列时，形成近光灯LED呈一列排列以及远光灯LED呈一列排列。而在近光灯LED与远光灯LED相对排列时，两者发光面之间的间距通常介于0.3mm～0.7mm之间；因此，近光灯所投射出的光束所形成的光型与远光灯所投射出的光束所形成的光型之间，会存在以下的问题：
一、在透镜较小的情况时(直径大约<5cm)，当近光灯LED所形成的光型的边缘(即明暗截止线)对应到-0.57°时，远光灯LED所形成的光型的亮区会朝上偏离，导致远光灯LED所形成的光型的最亮点(即hot spot)不在原点(即HV点)上，而无法符合法规(如欧规UN ECE R112或R113)要求；或是当远光灯LED所形成的光型的最亮点(即hot spot)对应到原点(即HV点)时，近光灯LED的所形成的光型的边缘(即明暗截止线)无法对应到-0.57°时而无法符合法规(如欧规UN ECE R112或R113)的要求，即如图1所示。
二、如图2所示，当近光灯LED与远光灯LED相对排列时，两者发光面之间具有一定的间隙时，如间隙介于0.3mm～0.7mm之间，因此，近光灯LED的所形成的光型与远光灯LED所形成的光型之间，会有暗影区W(即亮度严重不足)的存在。
故，如何通过结构设计的改良，如何克服上述的缺陷，已成为本领域所欲解决的重要课题之一。

第一实施例
请参阅图3至图9，分别为本发明第一实施例的照明装置的分解示意图、剖面示意图、光学模块的第一剖面示意图、光学模块的第二剖面示意图、光学模块的第三剖面示意图、光路示意图及近光灯光型示意图。本发明第一实施例提供一种照明装置Z，包括光源模块1、透镜模块2以及光学模块D。光源模块1包括至少一个第一发光单元11，至少一个第一发光单元11具有第一光源发光面110。透镜模块2对应于至少一个第一发光单元11。光学模块D可为透明件，光学模块D位于光源模块1以及透镜模块2之间，光学模块D包括第一导光单元D1，第一导光单元D1包括第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14，第一入光面D11连接于第二入光面D12，第二入光面D12与第一出光面D13之间具有第一预定夹角A1，第一预定夹角A1介于90度～150度，第二出光面D14对应于第一入光面D11；第一入光面D11平行于第一光源发光面110，第一入光面D11与第一光源发光面110之间具有第一预设间距C1，第一预设间距C1介于0.01mm～0.5mm。其中，透镜模块2具有焦点21以及焦距，透镜模块2以焦点21定义出焦平面210，焦平面210平行于第一光源发光面110，且透镜模块2的入射面200与第一光源发光面110之间的距离大于透镜模块2的焦距；其中，焦平面210与第一光源发光面110之间具有第二预设间距C2，第二预设间距C2介于0.2mm～5mm之间，其中以0.5mm～1.5mm为佳。
具体来说，本发明所提供的照明装置Z可应用于行动载具(例如汽车、机车或自行车等)的照明设备。照明装置Z包括了光源模块1、透镜模块2以及光学模块D。光源模块1包括了至少一个第一发光单元11，第一发光单元11可为发光二极管(Light-emitting diode,LED)，且第一发光单元11具有第一光源发光面110；其中，在本实施例中，第一发光单元11以两个作为示例，但不以此为限。透镜模块2对应光源模块1设置，透镜模块2的入射面200面向于光源模块1，透镜模块2的出射面201远离于光源模块1；其中，透镜模块2可为平凸型透镜，但不以此为限，现有技术领域者当知道任何可达成本发明的目的的透镜或透镜组(由一片以上的透镜组成)技术，都被包含在本发明所称的透镜模块的范围内。透镜模块2可具有焦点21，并且，透镜模块2以焦点21定义出焦平面210，焦平面210可为无限大的虚拟平面，但不以此为限。其中，透镜模块2的凸面(即出射面201)可为非球面曲面，或由多个非球面曲面构成，在本实施例中(如图4所示)，所述非球面曲面还具有光轴22(进一步在后面详述)，且非球面曲面外型在光轴的两侧为非对称(如图4的透镜模块2所示)，但本发明不以此为限。
而光源模块1与透镜模块2之间设置有光学模块D。光学模块D可包括第一导光单元D1，第一导光单元D1的材料为透明的塑胶或是玻璃，若是为塑胶，其材质可为光学级的PC或是PMMA，但本发明不以此为限。配合图5所示，第一导光单元D1可具有第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14。第一入光面D11面向于第一光源发光面110；其中，优选地，第一入光面D11可平行于第一光源发光面110，第一入光面D11与第一光源发光面110之间可具有第一预设间距C1，第一预设间距C1可介于0.01mm～0.5mm，第一预设间距C1优选可介于0.2mm～0.3mm。或者，如图6所示，第一入光面D11可约略平行于第一光源发光面110，即第一入光面D11相对于第一光源发光面110可呈倾斜状态，且第一入光面D11与第一光源发光面110之间也具有1度～30度的第一倾斜夹角B1；其中，第一入光面D11的倾斜方向可与第一出光面D13相同(如图6所示)，也可与第一出光面D13相反。另外，第一入光面D11可为平滑的光可穿透的面，但不以此为限，第一入光面D11也可为非平滑光可穿透的面(即表面上有导光微结构)。第二入光面D12与第一出光面D13连接，且第二入光面D12与第一出光面D13之间可具有第一预定夹角A1；其中，第一预定夹角A1可介于90度～150度，第一预定夹角A1优选可介于130度～140度，第一预定夹角A1以135度为更佳。第二出光面D14对应于第一入光面D11。此 外，配合图7所示，当第一预定夹角A1为90度时，第一导光单元D1可仅具有一个出光面，即第一出光面D13。
上述透镜模块2的焦平面210可平行于第一光源发光面110。并且，透镜模块2还具有焦距，焦距可为透镜模块2的入射面200到焦点21之间的距离，透镜模块2的入射面200与第一光源发光面110之间的距离可大于透镜模块2的焦距，但不以此为限；也就是说，焦平面210与第一光源发光面110之间具有第二预设间距C2，第二预设间距C2介于0.2mm～5mm之间，其中以0.5mm～1.5mm为佳，且以1.2mm为更佳，但本发明不以此为限。此外，透镜模块2的焦平面210也可约略平行于第一光源发光面110，如图6所示，焦平面210与第一光源发光面110之间也可具有1度～30度的夹角(类似上述第一倾斜夹角B1，在此不再特别标示)。
因此，在本发明的照明装置Z投射近光灯光型的光束时，第一发光单元11通过第一光源发光面110产生第一光束L1。接着，第一光源发光面110所产生的第一光束L1经由第一入光面D11进入第一导光单元D1后，经由第一出光面D13与第二出光面D14而射出至第一导光单元D1的外部；进一步来说，配合图5与图8所示，第一光束L1先经由第一入光面D11产生第一次折射而投射至第一出光面D13与第二出光面D14，并且，第一光束L1再经由第一出光面D13以及第二出光面D14的第二次折射而射出至第一导光单元D1的外部。接下来，由第一出光面D13以及第二出光面D14所折射出的第一光束L1会经由透镜模块2的入射面200进入透镜模块2后，再经由透镜模块2的出射面201而投射至测试屏幕(图中未示出，测试屏幕可为投影布幕，但不以此为限)上，并且，第一光束L1在测试屏幕上所形成的光型(即近光灯光型，如图9所示)的边缘(即明暗截止线)可落在HV点以下的固定角度范围，此固定角度范围可为-0.57°±0.3°，但本发明不以此为限。
由此，本发明所提供的照明装置Z通过上述的技术方案，当第一导光单元D1没有完全将第一光源发光面110完全罩住时(本发明不以此为限)，由第一光源发光面110所投射出的第一光束L1，其中一部分(即远离透镜模块2的光轴22的部分)不会经由光学模块D的折射，而直接进入透镜模块2，而所述部分的第一光束L1由透镜模块2投出后，会落在明暗截线以下，远离明暗截止线的区域；而另一部分的第一光束L1会经由光学模块D的第一导光单元D1的折射(如图8所示，图中的发光点为第一光源发光面110中较靠近光轴22的发光点)而改变路线，再进入透镜模块2中，进而使得另一部分的第一光束L1由透镜模块2投出后，可落在所形成的光型的 边缘(即明暗截止线)，且落在HV点以下的固定角度范围上，此固定角度范围可为-0.57°±0.3°，然而本发明不以此为限。并且，本发明的照明装置Z同时投射出近光灯光束与远光灯光束时，远光灯LED所形成的光型的最亮点(即hot spot)会在原点(即HV)，且近光灯LED所形成的光型的边缘(即明暗截止线)可成功的对应到HV点以下的固定角度范围，此固定角度范围可为-0.57°±0.3°。
进一步地，第二出光面D14可平行于第一入光面D11，且第二出光面D14可为雾面或为非平滑的光可穿透的光学面结构；其中，第一导光单元D1的厚度H介于0.2mm～1.0mm。其中，第一导光单元D1的厚度H优选可介于0.5-0.6mm。举例来说，配合图5所示，本发明的第二出光面D14可与第一入光面D11相互平行，因此，第二出光面D14也与第一光源发光面110相互平行。并且，第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14也可为平滑的光可穿透的光学面，但不以此为限。此外，第二出光面D14也可约略平行于第一入光面D11，即类似上述第一入光面D11约略平行于第一光源发光面110的方式，在此不再特别说明。
更进一步地，第二入光面D12与第一出光面D13的相接位置P位于焦平面210与第二出光面D14之间。举例来说，配合图5所示，本发明的第二入光面D12与第一出光面D13的相接位置P的位置在焦平面210与第二出光面D14之间，并可位于透镜模块2的焦点21以上的位置(即光轴22以上的区域)，其中以靠近透镜光轴22的附近为佳，且此相接位置P相对于明暗截止线的位置。进一步来说，本发明的第二入光面D12与第一出光面D13的相接位置P也可位于透镜模块2的焦点21以上且在第一发光单元11的第一发光面110的中心轴110a以下的范围之间，其中以位于较靠近透镜光轴22的区域为佳；即相接位置P可以位于光轴22与第一发光面110的中心轴110a之间、或者位于透镜模块2的焦点21以上且靠近第一发光单元11的下方基准面110c，其中下方基准面110c靠近第一发光面110的边缘或在第一发光面110的边缘上；另外，第一发光单元11的下方基准面110c与第一发光单元11的下缘侧110b的表面可以重叠且共面。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第二实施例
请参阅图10及图11，分别为本发明第二实施例的照明装置的光学模块的剖面示意图及光路示意图，并请一并参阅图1至图9。如图所示，本实施例的照明装置Z与上述第一实施例的照明装置Z相同的元件的作动方式相似，在此不再赘述，值得注意 的是，在本实施例中，第一导光单元D1进一步可包括第三出光面D15以及连接面D16，第三出光面D15连接于第二出光面D14，连接面D16连接于第一出光面D13与第三出光面D15；其中，连接面D16与第一出光面D13之间具有第二预定夹角A2，第二预定夹角A2介于40度～60度。
举例来说，配合图10所示，本发明的第一导光单元D1进一步包括了第三出光面D15以及连接面D16。第三出光面D15的一端可与第二出光面D14连接，第三出光面D15的另一端可与连接面D16的一端连接，而连接面D16的另一端可与第一出光面D13连接。并且，连接面D16与第一出光面D13之间可形成第二预定夹角A2，第二预定夹角A2可介于40度～60度，第二预定夹角A2优选可为48度。另外，连接面D16与第三出光面D15的交点位于第二入光面D12与第一出光面D13的相接位置P及第二出光面D14之间。
因此，在第一光源发光面110产生第一光束L1后，其中一部分第一光束L1不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第一光束L1会经由光学模块D的第一导光单元D1的折射(如图11所示，图中的发光点为第一光源发光面110中较靠近光轴22的发光点)而改变路线，再进入透镜模块2中。进一步来说，另一部分的第一光束L1会先经由第一入光面D11产生第一次的折射而投射至第一出光面D13、第三出光面D15以及第二出光面D14后，再经由第一出光面D13、第三出光面D15以及第二出光面D14产生第二次的折射而射出至第一导光单元D1的外部。接下来，由第一出光面D13、第二出光面D14以及第三出光面D15折射出的第一光束L1经由透镜模块2投射在测试屏幕上所形成的光型(即近光灯光型，如图9所示)的边缘(即其明暗截止线)可以落在HV点以下的固定角度范围，所述固定角度范围可为-0.57°±0.3°上，但本发明不以此为限。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第三实施例
请参阅图12及图13，分别为本发明第三实施例的照明装置的光学模块的剖面示意图以及光路示意图，并请一并参阅图1至图11。如图所示，本实施例的照明装置Z与上述各实施例的照明装置Z相同的元件的作动方式相似，在此不再赘述，值得注意的是，在本实施例中，第二出光面D14倾斜于第一入光面D11，第一导光单元D1还进一步包括多个第三出光面D151～D153，多个第三出光面D151～D153位于第一出光面D13与第二出光面D14之间，多个第三出光面D15彼此连接，且其中一个第三出 光面D153连接于第一出光面D13，另外一个第三出光面D151连接于第二出光面D14。其中，第一出光面D13、第二出光面D14与每一个第三出光面D151～D153可为平面结构，且第一出光面D13、第二出光面D14与多个第三出光面D151～D153的斜率彼此不同，并且，按第一出光面D13至第二出光面D14的顺序，第一出光面D13、多个第三出光面D151～D153与第二出光面D14的斜率愈来愈抖；或者，第一出光面D13、第二出光面D14与每一个第三出光面D151～D153也可以为曲面结构，且第一出光面D13、多个第三出光面D151～D153与第二出光面D14的曲率彼此不同，且其曲率半径依序按第一出光面D13、多个第三出光面D151～D153到第二出光面D14的顺序愈来愈大。
举例来说，配合图12所示，本发明的第一导光单元D1朝向透镜模块2的出光面可为连续型的曲面或斜面结构。第一导光单元D1进一步可包括多个第三出光面D151～D153。多个第三出光面D151～D153彼此连接，第三出光面D153的一端连接于第一出光面D13，且第三出光面D151的一端与第二出光面D14连接。其中，第一出光面D13、第二出光面D14以及多个第三出光面D151～D153可为彼此斜率不同的斜面，或者彼此曲率不同的曲面，但不以此为限。
因此，在第一光源发光面110产生第一光束L1后，其中一部分的第一光束L1不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第一光束L1会经由光学模块D的第一导光单元D1的折射(如图13所示，图中的发光点为第一光源发光面110中较靠近光轴22的发光点)而改变路线，再进入透镜模块2中。进一步来说，另一部分的第一光束L1会先经由第一入光面D11产生第一次的折射而投射至第一出光面D13、第二出光面D14以及多个第三出光面D151～D153，再经由第一出光面D13、第二出光面D14以及多个第三出光面D151～D153产生第二次的折射而射出至第一导光单元D1的外部。接下来，由第一出光面D13以及第二出光面D14以及多个第三出光面D151～D153产生折射出的第一光束L1可经由透镜模块2在测试屏幕所形成的光型(即近光灯光型，如图9所示)的边缘(即明暗截止线)可落在HV点以下的固定角度范围，此固定角度范围可为-0.57°±0.3°上，但本发明不以此为限。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第四实施例
请参阅图14至图22，分别为本发明第四实施例的照明装置的分解示意图、剖面示意图、光源模块的主视示意图、第一光路示意图、第二光路示意图、第三光路示意 图、远光灯光型示意图、支撑单元的第一立体示意图以及支撑单元的第二立体示意图，并请一并参阅图1至图13。如图所示，本实施例的照明装置Z与上述各实施例的照明装置Z相同的元件的作动方式相似，在此不再赘述，值得注意的是，在本实施例中，光源模块1还进一步包括至少一个第二发光单元12，至少一个第二发光单元12靠近于至少一个第一发光单元11，至少一个第二发光单元12具有第二光源发光面120，且第二光源发光面120与第一光源发光面110共面(coplanar)；其中，透镜模块2具有光轴22，光轴22垂直于第二光源发光面120。
具体来说，配合图5、图14至图16所示，本发明的光源模块1还进一步可包括至少一个第二发光单元12，第二发光单元12可为发光二极管(Light-emitting diode,LED)，且第二发光单元12可具有第二光源发光面120；其中，在本实施例中，第二发光单元12以两个作为示例，但不以此为限。多个第一发光单元11可位于多个第二发光单元12的上方，第二光源发光面120与第一光源发光面110可位于同一个平面上或不同的平面上，且第一发光单元11以及第二发光单元12可电连接及热传导连接于金属基板(如后所述)。其中，第一发光单元11可为近光灯的发光源，即所投射出来的光线所形成的光型为近光灯光型(或第一光型)；第二发光单元12可为远光灯的发光源，即第二发光单元12所投射出来的光线所形成的光型为远光灯光型(或第二光型)，但不以此为限。并且，透镜模块2还可具有光轴22，光轴22通过透镜模块2的焦点21，并可垂直于第二光源发光面120，且光轴22可通过第二光源发光面120，并靠近于第一光源发光面110的位置。其中，当第二发光单元12数量为一个的时候，光轴22对应于第二光源发光面120上且位于第二发光单元12两侧之间的正中间位置上，但不以此为限；而当第二发光单元12数量为两个的时候，光轴22对应于两个第二光源发光面120之间的位置且位于两个第二发光单元12之间的正中间位置上，但不以此为限。换句话说，透镜模块2的焦点21不在第一光源发光面110上，其中以位于第二光源发光面120的边界E(如图16所示)内，或位于第二发光单元12的第二光束L2朝透镜模块2投射的区域内，并且较靠近第一发光单元11的区域为佳。
因此，当第二发光单元12应用于第一实施例的光学模块D时，在第二光源发光面120产生第二光束L2后，其中一部分的第二光束L2不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第二光束L2会经由光学模块D的第一导光单元D1的折射(如图17所示，图中的发光点仅表示第二光源发光面120上的其中一个发 光点，且较靠近于第一发光单元11)而改变路线，再进入透镜模块2中。进一步来说，另一部分的第二光束L2会先经由第二入光面D12产生第一次的折射而投射至第二出光面D14，并在第二出光面D14产生全反射而由第一导光单元D1的上缘面D17射出至第一导光单元D1的外部。接下来，由第一导光单元D1的上缘面D17折射出的第二光束L2经由透镜模块2的出射面201而投射至测试屏幕后，在测试屏幕所形成的光型(如图20所示)可弥补近光灯LED的所形成的光型与远光灯LED所形成的光型之间的暗影区(如图2中所示的暗影区W)。
其中，当第二发光单元12应用于第二实施例的光学模块D时，在第二光源发光面120产生第二光束L2后，其中一部分的第二光束L2不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第二光束L2会经由光学模块D的第一导光单元D1的折射(如图18所示，图中的发光点仅表示第二光源发光面120上较靠近于第一发光单元11的其中一个发光点)而改变路线，再进入透镜模块2中。进一步来说，另一部分的第二光束L2会先经由第二入光面D12产生第一次的折射而投射至第二出光面D14，并在第二出光面D14产生全反射而由第一导光单元D1的上缘面D17射出至第一导光单元D1的外部。接下来，由第一导光单元D1的上缘面D17折射出的第二光束L2经由透镜模块2的出射面201而投射至测试屏幕后，在测试屏幕所形成的光型(如图20所示)可弥补近光灯LED的所形成的光型与远光灯LED所形成的光型之间的暗影区(如图2中所示的暗影区W)。
而当第二发光单元12应用于第三实施例的光学模块D时，在第二光源发光面120产生第二光束L2后，其中一部分的第二光束L2不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第二光束L2会经由光学模块D的第一导光单元D1的折射(如图19所示，图中的发光点仅表示第二光源发光面120上较靠近于第一发光单元11的一个发光点)而改变路线，再进入透镜模块2中。进一步来说，另一部分的第二光束L2会先经由第二入光面D12产生第一次的折射而投射至第二出光面D14，并在第二出光面D14产生全反射而由第一导光单元D1的上缘面D17射出至第一导光单元D1的外部。接下来，由第一导光单元D1的上缘面D17折射出的第二光束L2经由透镜模块2的出射面201而投射至测试屏幕后，在测试屏幕所形成的光型(如图20所示)可弥补近光灯LED的所形成的光型与远光灯LED所形成的光型之间的暗影区(如图2中所示的暗影区W)。
由于本发明的照明装置Z同时投射出近光灯光束与远光灯光束时，因透镜模块2 的焦点21位于第二光源发光面120的边界E内，或者，位于第二发光单元12的第二光束L2朝透镜模块2投射的区域内，其中以较靠近第一发光单元11的区域为佳时，第二发光单元12(远光灯LED)所形成的光型的最亮点会在原点(即HV点)，第一发光单元11(近光灯LED)所形成的光型的边缘(即明暗截止线)可成功的对应到HV点以下的固定角度范围，此固定角度范围为-0.57°±0.3°，本发明不以此为限；并且，同时还能减少当近光灯LED与远光灯LED相对排列时，两者发光面(即第一光源发光面110与第二光源发光面120)之间具有一定的间隙时，近光灯LED的光型与远光灯LED的光型之间会有暗影区(如图2中所示的暗影区W)的情形产生。
进一步地，光学模块D还进一步包括支撑单元D2，支撑单元D2的中心具有贯穿本体的开口D200，第一导光单元D1位于开口D200中；其中，支撑单元D2与第一导光单元D1为单一元件。举例来说，配合图14、图15、图21及图22所示，光学模块D进一步可包括支撑单元D2，其可为透明的塑胶或是玻璃，若是为塑胶，其材质可为光学级的PC或是PMMA，但本发明不以此为限。支撑单元D2的中心具有贯穿支撑单元D2本体的开口D200，第一导光单元D1可位于支撑单元D2的开口D200中。支撑单元D2与第一导光单元D1可为各自独立的元件、或者支撑单元D2与第一导光单元D1可为单一元件。进一步来说，配合图21及图22所示，支撑单元D2可包括主体件D20、第一固定件D21以及第二固定件D22。主体件D20具有开口D200、上肋部D201以及下肋部D202，开口D200位于上肋部D201与下肋部D202之间；并且，第一导光单元D1设置于开口D200中，并位于上肋部D201与下肋部D202之间。第一固定件D21与第二固定件D22可对称地设置于主体件D20的两侧，但本发明不以此为限。
更进一步地，照明装置Z还进一步包括基板模块3以及多个固定模块4。举例来说，配合图14、图15、图21及图22所示，基板模块3可为金属材质的基板，并同时兼具导电及导热的特性，但不以此为限；光源模块1可设置于基板模块3上。多个固定模块4可为锁固元件，例如螺丝，但不以此为限。并且，支撑单元D2的两侧可分别具有穿孔D210、D220，即第一固定件D21与第二固定件D22各自具有穿孔D210、D220。因此，通过每一个固定模块4穿过各自所对应的穿孔D210、D220，并能拆卸地连接于基板模块3，以将光学模块D固定于基板模块3，且光学模块D覆盖光源模块1。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第五实施例
请参阅图23至图25，分别为本发明第五实施例的照明装置的光学模块的剖面示意图、第一光路示意图及第二光路示意图，并请一并参阅图1至图22。如图所示，本实施例的照明装置Z与上述各实施例的照明装置Z相同的元件的作动方式相似，在此不再赘述，值得注意的是，在本实施例中，光学模块D还包括第二导光单元D3，第二导光单元D3包括第三入光面D31、第四入光面D32、第四出光面D33以及第五出光面D34，第三入光面D31连接于第四入光面D32，第四入光面D32与第三出光面D33之间具有第三预定夹角A3，第三预定夹角A3介于90度～150度，第五出光面D34对应于第三入光面D31；其中，第三入光面D31平行于第二光源发光面120，第三入光面D31与第二光源发光面120之间具有第三预设间距C3，第三预设间距C3介于0.01mm～0.5mm。
举例来说，配合图23所示，本发明的光学模块D还包括第二导光单元D3，第二导光单元D3的材料可为透明的塑胶或是玻璃，若是为塑胶，其材质可为光学级的PC或是PMMA，但本发明不以此为限。第二导光单元D3可与第一导光单元D1相邻地设置于开口D200中，且第二导光单元D3连接于支撑单元D2的下肋部D202；其中，第二导光单元D3与下肋部D202可为各自独立的元件、或者第二导光单元D3与下肋部D202可为单一元件。第二导光单元D3对应于第二发光单元12的第二光源发光面120，第一导光单元D1对应于第一发光单元11的第一光源发光面110；其中，第二导光单元D3与第一导光单元D1之间具有第四预设间距C4，第四预设间距C4可介于0.5mm～1.5mm，第四预设间距C4优选可介于0.8mm～1.2mm，但不以此为限。第二导光单元D3可具有第三入光面D31、第四入光面D32、第四出光面D33以及第五出光面D34。第三入光面D31面向于第二光源发光面120；其中，优选地，第三入光面D31可平行于第二光源发光面120，第三入光面D31与第二光源发光面120之间可具有第三预设间距C3，第三预设间距C3可介于0.01mm～0.5mm，第三预设间距C3优选可介于0.2mm～0.3mm。或者，第三入光面D31可约略平行于第二光源发光面120，即第三入光面D31相对于第二光源发光面120可呈倾斜状态，且第三入光面D31与第二光源发光面120之间也可具有1度～30度的夹角(类似前述的第一倾斜夹角B1，在此不再特别示出)；其中，第三入光面D31的倾斜方向可与第四出光面D33相同，也可与第四出光面D33相反。第四入光面D32与第四出光面D33连接，且第四入光面D32与第四出光面D33之间可具有第三预定夹角A3；其中，第三预定夹角A3可 介于90度～150度，第三预定夹角A3优选可介于100度～155度，第三预定夹角A3以120度为更佳。第四出光面D34对应于第三入光面D31。
此外，第三入光面D31、第四入光面D32、第四出光面D33以及第五出光面D34可为平滑的光可穿透的光学面结构，但第四出光面D33以及第五出光面D34也可以是雾面或为非平滑的光可穿透的光学面结构。当第三预定夹角A3为90度时，第二导光单元D3可仅具有一个出光面，即第四出光面D33与第五出光面D34为共面型态(具体实施方式如前述第一实施例与图7所示，在此不再特别示出)。并且，第四出光面D33可为平面，或者为钝角、弧面等折面结构。
因此，在第一光源发光面110所产生的较大角度且无法通过第一导光单元D1的第一光束L1，可经由第四入光面D32折射而进入第二导光单元D3中(如图24所示，图中的发光点仅表示第一光源发光面110上较靠近于第二发光单元120的一个发光点)。若是第四出光面D33及第五出光面D34为雾面时，进入第二导光单元D3中的第一光束L1可经由第四出光面D33以及第五出光面D34的散射(scattering)而离开第二导光单元D3，以投射到透镜模块2。最后，由透镜模块2投射出的第一光束L1可用于弥补且增加近光灯所形成的光型的余光区的亮度(比较图9余光区Y的亮度与图1余光区Y的亮度，图9的余光区Y亮度明显远高于图1，并且余光区的范围还远较图1为宽广)。
并且，在第二光源发光面120所产生的部分第二光束L2投射到第二导光单元D3，并经由第三入光面D31进入第二导光单元D3后(如图25所示，图中的发光点仅表示第二光源发光面120上的其中一个发光源)，第二光束L2可经由第四出光面D33以及第五出光面D34的折射，而投射到透镜模块2。最后，由透镜模块2投射出的第二光束L2可用于填补远光灯所形成的光型，使得远光灯所形成的光型更加饱满。
进一步地，第三入光面D31平行于焦平面210，且焦平面210位于第二光源发光面120与第五出光面D34之间；其中，焦点21以及光轴22位于第二入光面D12与第四入光面D32之间。举例来说，透镜模块2的焦平面210可平行于第二导光单元D3的第三入光面D31，但，焦平面210也可约略平行于第二导光单元D3的第三入光面D31，即焦平面210与第三入光面D31之间可具有1度～30度的夹角(类似前述第一倾斜夹角B1，在此不再特别示出)。
值得注意的是，本发明的第二导光单元D3与支撑单元D2可为一体成型的单一构件，也可以是各自独立的两个构件。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。

举例来说，配合图26及图27所示，本发明的照明装置Z的光学模块D还可进一步包括反射单元D4，反射单元D4可为反射镜或其他具反射功能的元件。反射单元D4可设置于在支撑单元D2的下方，且反射单元D4的两侧分别连接于支撑单元D2的第一固定件D21与第二固定件D22。反射单元D4具有反射面D40，反射面D40可对应于第二导光单元D3与下肋部D202。并且，反射面D40与第一光源发光面110之间、或反射面D40与第二光源发光面120之间可具有第四预定夹角A4，第四预定夹角A4可介于120度～150度；其中，第四预定夹角A4优选可介于130度～140度，并以135度为最佳，但本发明不以此为限。
进一步来说，配合图26及图27所示，第二导光单元D3还可包括第六出光面D35，第六出光面D35可与第五出光面D34连接，且第六出光面D35与第五出光面D34的连接处R可为圆角、锐角或直角，本实施例中以圆角作为示例，但不以此为限。第六出光面D35与第五出光面D34之间可具有第五预定夹角A5，第五预定夹角A5可介于70度～110度。并且，支撑单元D2的下肋部D202还可具有内表面D2020以及对应于内表面D2020的外表面D2021。内表面D2020与第二导光单元D3的第三入光面D31连接，且内表面D2020与第三入光面D31之间可具有第六预定夹角A6，第六预定夹角A6可介于70度～110度。外表面D2021与第二导光单元D3的第六出光面D35连接。因此，第二导光单元D3与下肋部D202可略呈L型，但不以此为限。此外，第三入光面D31、第三入光面D32与内表面D2020可为平滑的光可穿透的光学表面，而第四出光面D33、第五出光面D34、第六出光面D35与外表面D2021可为光可穿透的雾面结构，但本发明不以此为限。
因此，当第一导光单元D1没有完全将第一光源发光面110完全罩住时(但本发 明不以此为限)，由第一光源发光面110所投射出的第一光束L1，其中一部分的第一光束L1(即靠近光轴22的部分)不会经由第一导光单元D1的折射，而会投射到第二导光单元D3的第三入光面D31与第四入光面D32与投射到内表面D2020，并经由第三入光面D31与第四入光面D32及内表面D2020的折射而进入第二导光单元D3中(如图28所示，图中的发光点仅表示第一光源发光面110上的其中一个发光点，且较靠近于第二发光单元12)。若是第四出光面D33、第五出光面D34、第六出光面D35及连接处R为雾面时，进入第二导光单元D3中的第一光束L1可经由第四出光面D33、第五出光面D34、第六出光面D35及连接处R的散射而离开第二导光单元D3，并投射到反射单元D4的反射面D40。接着，第一光束L1经由反射面D40的反射而投射到透镜模块2，使得第一光束L1由透镜模块2投出后，可落在所形成的近光灯光型的上方，即落在HV点(即明暗截止线)上方的范围，进而可补强余光区Y(比较图29余光区Y的亮度与图9余光区Y的亮度，图29的余光区Y亮度明显远高于图9，并且余光区的范围还远较图9为宽广)的光源亮度；但，本发明不以此为限。
更进一步地，第二导光单元D3位于第一导光单元D1与反射单元D4之间；其中，反射面D40具有靠近于支撑单元D2的上侧边D400以及远离支撑单元D2的下侧边D401，上侧边D400与光轴22之间具有第五预设间距C5，第五预设间距C5介于1.5mm～10mm。
举例来说，配合图26及图27所示，本发明的反射面D40具有上侧边D400以及下侧边D401；其中，上侧边D400与下侧边D401指反射面D40的边缘或边角，而非指反射面D40两侧的平面。上侧边D400与光轴22之间可具有第五预设间距C5，第五预设间距C5可介于1.5mm～10mm，优选可介于1.5mm～5mm，但不以此为限。其中，上侧边D400可与第一光源发光面110、第二光源发光面120或其两者位于同一个基准面上(即共面)，上侧边D400也可以置于以第一光源发光面110或第二光源发光面120为基准面的前后±5mm的位置上，但不以此为限。
此外，本发明的反射单元D4的外型可为四角形，且上侧边D400与下肋部D202的外表面D2021之间保持一预定的距离(本发明所属技术领域中技术人员可由上述第五预设间距C5来推知，在此不再特别说明)，如图26及图27所示。但是，本发明的反射单元D4的外型也可为多角形，且上侧边D400与外表面D2021之间没有间隙；即，反射单元D4的上侧边D400连接于主体件D20、外表面D2021、第一固定件D21以及第二固定件D22。

然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第七实施例
请参阅图30至图35，分别为本发明第七实施例的照明装置的立体示意图、光学模块的第一剖面示意图、光学模块的第二剖面示意图、第一光路示意图、第二光路示意图以及光学模块的第三剖面示意图，并请一并参阅图1至图27。如图所示，本发明第七实施例提供一种照明装置Z，其包括光源模块1、透镜模块2以及光学模块D。光源模块1包括至少一个第一发光单元11，至少一个第一发光单元11具有第一光源发光面110。透镜模块2对应于至少一个第一发光单元11。光学模块D位于光源模块1以及透镜模块2之间，光学模块D包括第一导光单元D1，第一导光单元D1包括第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14，第一入光面D11连接于第二入光面D12，第二入光面D12与第一出光面D13之间具有第一预定夹角A1，第一预定夹角A1可介于40度～60度，第二出光面D14对应于第二入光面D12；其中，第一入光面D11平行于第一光源发光面110，第一入光面D11与第一光源发光面110之间具有第一预设间距C1，第一预设间距C1可介于0.01mm～0.5mm。其中，透镜模块2具有焦点21以及焦距，透镜模块2以焦点21定义出焦平面210，焦平面210平行于第一光源发光面110，且透镜模块2的入射面200与第一光源发光面110之间的距离大于透镜模块2的焦距；其中，焦平面210与第一光源发光面110之间具有第二预设间距C2，第二预设间距C2介于0.2mm～5mm之间，其中以0.5mm～1.5mm为佳，且以1.2mm为更佳，但本发明不以此为限。
具体来说，根据图31与图5比较所示，本实施例所提供的照明装置Z与前述第一实施例的照明装置Z的差异在于，本实施例的照明装置Z的光学模块D可包括第一导光单元D1，第一导光单元D1包括了第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14。第一导光单元D1可为平行四边形结构或四边形结构，且第二入光面D12与第一出光面D13之间可形成第一预定夹角A1；其中，第一预定夹角A1可介于40度～60度，第一预定夹角A1优选可为45度。并且，第一入光面D11可平行于第一光源发光面110，或者，第一入光面D11约略平行于第一光源发光面110，并与第一光源发光面110之间具有1度～30度的夹角。第一入光面D11可为光学平面，但本发明不以第一入光面D11为平面为限，第一入光面D11也可为曲面或凹凸面。第一入光面D11与第一光源发光面110之间可具有第一预设间距C1；其中，第一预设间距C1可介于0.01mm～0.5mm，第一预设间距C1优选可介于0.2mm～0.3mm。
而透镜模块2可具有焦点21以及焦距，焦点21不在第一光源发光面110上，其中以位于第二光源发光面120的边界E内，或位于第二发光单元12的光线朝透镜模块2射出的区域内，其中以较靠近第一发光单元11的区域为佳(如前述第四实施例以及图32所示)，而透镜模块2的焦距可为透镜模块2的入射面200到焦点21之间的距离。焦平面210可平行于第一光源发光面110，如图31所示；或者，焦平面210约略平行于第一光源发光面110，如图32所示，焦平面210与第一光源发光面110之间也可具有1度～30度的夹角(类似前述第一倾斜夹角B1，如图6所示，在此不再特别标示)。并且，透镜模块2的入射面200与第一光源发光面110之间的距离可大于透镜模块2的焦距，但不以此为限；也就是说，焦平面210与第一光源发光面110之间具有第二预设间距C2，第二预设间距C2介于0.2mm～5mm之间，其中以0.5mm～1.5mm为佳，且以1.2mm为更佳，但本发明不以此为限。
因此，在本发明的照明装置Z投射出光束时，当第一导光单元D1没有完全将第一光源发光面110完全罩住时(本发明不以此为限)，第一发光单元11通过第一光源发光面110所产生的第一光束L1，其中一部分的第一光束L1(即远离透镜光轴22的部分)不会经由光学模块D的折射，而直接进入透镜模块2，而所述其中一部分的第一光束L1由透镜模块2投出后，会落在明暗截线以下，远离明暗截止线的区域；而另一部分的第一光束L1即位于第一光源发光面110中较靠近光轴22的发光点，会经由光学模块D的第一导光单元D1的折射(如图33及图34所示)而改变路线，再 进入透镜模块2中，进而使得另一部分的第一光束L1由透镜模块2投出后，可落在所形成的光型的边缘(即明暗截止线)，且落在HV点以下的一固定角度范围上，此固定角度范可为-0.57°±0.3°，但本发明不以此为限。
进一步来说，经过第一导光单元D1的另一部分的第一光束L1的光线行经的路径，大致可分为两种不同的路径，分别可为全反射路径或非全反射路径，即另一部分的第一光束L1可分为属于全反射路径的第一光束L11以及属于非全反射路径的第一光束L12。为使附图清晰可辨，图33只标示全反射路径的第一光束L11，其他未标示的为L12。配合图33所示，第一光束L11在全反射路径中，先由第一光源发光面110投射至第一入光面D11，并经由第一入光面D11的第一次折射而进入第一导光单元D1后，再经由第二出光面D14的第一次全反射以及第二入光面D12的第两次全反射后，最后经由第一出光面D13的第二次折射而射出至第一导光单元D1的外部。换句话说，第一光源发光面110所产生的第一光束L11，从进入第一导光单元D1之后，要经过两次折射以及两次全反射之后，第一光束L11才会离开第一导光单元D1。接下来，由第一出光面D13折射出的第一光束L11经由透镜模块2的投射而在测试屏幕上所形成的光型(如图9所示)的边缘(即明暗截止线)可落在HV点以下的固定角度范围上，此固定角度范围可为-0.57°±0.3°，但本发明不以此为限。需要说明的事，要落在明暗截止线上的光线，需要经过两次的折射及两次的全反射。
再请配合图34所示，第一光束L12在非全反射的路径中，先由第一光源发光面110投射至第一入光面D11与第二入光面D12，并经由第一入光面D11与第二入光面D12的第一次折射而进入第一导光单元D1后，再经由第一出光面D13与第二出光面D14的第二次折射而射出至第一导光单元D1的外部。换句话说，第一光束L1从进入第一导光单元D1后，经过两次的折射，才会离开第一导光单元D1，接着，再经由透镜模块2而投射到测试屏幕上所形成的光型(如图9所示)，其明暗截止线会落在HV点以下的一固定角度范围，此固定角度范围可为-0.57°±0.3°，但本发明不以此为限。
进一步地，第一入光面D11可平行于第一出光面D13，第二入光面D12可平行于第二出光面D14；其中，第一导光单元D1的厚度H可介于0.2mm～1.0mm，第一导光单元D1的厚度H较佳可介于0.5mm～0.6mm。举例来说，配合图31所示，第一入光面D11可与第一出光面D13相互平行。但是，如图32所示，第一入光面D11也可约略平行于第一出光面D13，而与第一出光面D13之间具有1度～15度的第二倾斜夹 角B2。第二入光面D12可与第二出光面D14相互平行，但第二入光面D12也可约略平行于第二出光面D14，并与第二出光面D14之间具有1度～15度的第三倾斜夹角B3。并且，第二入光面D12与光轴22之间可形成35度～55度的第四倾斜夹角B4，其中，第四倾斜夹角B4以40度～50度为佳，而以45度为最佳。因此，第一导光单元D1可为平行四边形或是四边形。
更进一步地，第二入光面D12与第一出光面D13的相接位置P可位于透镜模块2的光轴22与第一发光单元11的第一发光面110的中心轴110a之间。举例来说，配合图31所示，本发明的第二入光面D12与第一出光面D13的相接位置P的位置在光轴22与中心轴110a之间，即光轴22以上的区域，且此相接位置P对应于明暗截止线的位置，其中以相接位置P位于透镜模块2的光轴22的附近为佳。进一步来说，本发明的第二入光面D12与第一出光面D13的相接位置P也可位于透镜模块2的焦点21以上且在第一发光面110的中心轴110a以下的范围之间；即相接位置P可以位于光轴22与第一发光面110的中心轴110a之间，其中以较靠近光轴22的位置为佳、或者相接位置P可以位于光轴22以上且靠近第一发光单元11的下方基准面110c，其中下方基准面110c靠近第一发光面110的边缘或在第一发光面110的边缘上；另外，第一发光单元11的下方基准面110c也可与第一发光单元11的下缘侧110b的表面重叠且共面。
然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。
第八实施例
请参阅图36及图37，分别为本发明第八实施例的照明装置的分解示意图以及光路示意图，并请一并参阅图1至图35。如图所示，本实施例的照明装置Z与上述第七实施例的照明装置Z相同的元件的作动方式相似，在此不再赘述，值得注意的是，在本实施例中，光源模块1还进一步包括至少一个第二发光单元12，至少一个第二发光单元12紧靠近于至少一个第一发光单元11，至少一个第二发光单元12具有第二光源发光面120，且第二光源发光面120与第一光源发光面110共面(coplanar)，但本发明不以此为限；其中，透镜模块2具有光轴22，光轴22垂直于第二光源发光面120。
具体来说，配合图25、图30及图31所示，本发明的光源模块1还进一步可包括至少一个第二发光单元12，第二发光单元12可为发光二极管(Light-emitting diode,LED)，且第二发光单元12可具有第二光源发光面120；其中，在本实施例中，第二发光单元12以两个作为示例，但不以此为限。多个第一发光单元11可位于多个第二 发光单元12的上方，且第二光源发光面120与第一光源发光面110位于同一个水平面上，但本发明不以此为限；其中，第一发光单元11可为近光灯的发光源，第二发光单元12可为远光灯的发光源，但不以此为限。透镜模块2还可具有光轴22，光轴22可通过透镜模块2的中心或中心附近，并且，光轴22可通过透镜模块2的焦点21且垂直于第二光源发光面120，光轴22可通过第二光源发光面120且较靠近第一光源发光面110的位置，但本发明不以光轴22可垂直于第二光源发光面120为限。其中，当第二发光单元12数量为一个的时候，光轴22对应于第二光源发光面120上且位于第二发光单元12两侧之间的正中间位置上；而当第二发光单元12数量为两个的时候，光轴22对应于两个第二光源发光面120之间的位置且位于两个第二发光单元12之间的正中间位置上。
因此，配合图31及图37所示，在第二光源发光面120产生第二光束L2时，其中一部分的第二光束L2不会经由光学模块D的折射，而直接进入透镜模块2，另一部分的第二光束L2会经由光学模块D的第一导光单元D1的折射(如图37所示，图中的发光点仅为第二光源发光面120上紧邻于光轴的其中一个发光点)而改变路线，再进入透镜模块2中。最后，其中一部分的第二光束L2与另一部分的第二光束L2由透镜模块2射出后，会形成远光灯的光型，并且远光灯LED所形成的光型的最亮点会在原点(即HV)上。而第一发光单元11(即近光灯LED)所形成的光型的边缘(即明暗截止线)可成功的对应到HV点以下(-0.57°±0.3°)，并且同时还能减少近光灯LED与远光灯LED紧密相对排列时(第一光源发光面110与第二光源发光面120之间具有一定的间隙时)，近光灯光型与远光灯LED光型之间会有暗影区的情形(如图20所示)。
进一步地，光学模块D还进一步包括支撑单元D2，支撑单元D2的中心具有开口D200，第一导光单元D1位于开口D200中；其中，支撑单元D2与第一导光单元D1为单一元件。举例来说，配合图31及图36所示，光学模块D进一步可包括支撑单元D2，支撑单元D2可为透明或不透明的材质。第一导光单元D1可位于支撑单元D2的开口D200中。支撑单元D2与第一导光单元D1可为各自独立的元件或者单一元件。
更进一步地，照明装置Z还进一步包括基板模块3以及多个固定模块4。举例来说，配合图36所示，基板模块3可为金属材质的基板，但不以此为限；光源模块1可设置于基板模块3上。多个固定模块4可为锁固元件，例如螺丝，但不以此为限。并且，支撑单元D2的两侧可分别具有穿孔D210、D220。因此，通过每一个固定模块 4穿过各自所对应的穿孔D210、D220，并能拆卸地连接于基板模块3，以将光学模块D固定于基板模块3，且光学模块D覆盖光源模块1。
更进一步地，配合图36及图37所示，光学模块D还可包括第二导光单元D3，第二导光单元D3包括第三入光面D31、第四入光面D32、第四出光面D33以及第五出光面D34，第三入光面D31连接于第四入光面D32，第四入光面D32与第四出光面D33之间具有第三预定夹角A3，第三预定夹角A3介于90度～150度，第五出光面D34对应于第三入光面D31；其中，第三入光面D31平行于第二光源发光面120，第三入光面D31与第二光源发光面120之间具有第三预设间距C3，第三预设间距C3介于0.01mm～0.5mm。具体实施方式与前述第五实施例相似，在此不再特别说明。
更进一步地，光学模块D还可包括反射单元D4，反射单元D4连接于支撑单元D2，反射单元D4可具有反射面D40，反射面D40与第一光源发光面110或第二光源发光面120之间可具有第四预定夹角A4，第四预定夹角A4可介于120度～150度。具体实施方式如前述第六实施例以及图26至图28所示，在此不再特别说明。
更进一步地，第二导光单元D3位于第一导光单元D1与反射单元D4之间；其中，反射面D40可具有靠近于支撑单元D2的上侧边D400以及远离支撑单元D2的下侧边D401，上侧边D400与光轴22之间可具有第五预设间距C5，第五预设间距C5可介于1.5mm～10mm。具体实施方式如前述第六实施例以及图26至图28所示，在此不再特别说明。
更进一步地，第三入光面D31平行于焦平面210，且焦平面210位于第二光源发光面120与第五出光面D34之间；其中，焦点21以及光轴22位于第二入光面120与第五入光面D34之间。具体实施方式与前述第五实施例相似，在此不再特别说明。
