本实施例的该照明模块10内部设有至少一第一透镜(未图示)，该至少一第一透镜可以依据具体需求而设置多个进行调整。该照明模块10自内部发射一光线(未图示)行经该至少一第一透镜，依据该至少一第一透镜本身的结构设计(例如聚焦、发散效果的凹/凸透镜)，而自该出光部12产生该第一光束14，使该第一光束14形成该第一发散角β1(35度至55度)。另外，该照明模块10设定光圈为1.2～1.8(较佳为1.37)。其中通过该照明模块10与该反射装置20分别设置于该光轴50的一水平面54的不同侧，结合该第一发散角β1使得该反射装置20更加贴近该照明模块10，进而使得照明系统小型化。该照明模块10所产生的该第一光束14于该反射装置20所形成的夹角为66～73度。该照明模块10与该反射装置20分别设置于该投射模块40的该光轴50的一径向平面52上，且该照明模块10设置于该光轴50所在的一铅垂面56上。
本发明的反射照明系统更包含一投射模块40，该投射模块40设置于该光轴50上，该投射模块40的一端设有一入射面42，另一端设有一出射面44，该入射面42接收该第三光束32后，由该出射面44投射一第四光束46；其中，该投射模块40更包含至少一第二透镜(未图示)，该至少一第二透镜可以依据具体需求而设置多个进行调整，其结构、工作功效如同该照射模块10所设置的该至少一第一透镜。又，该第一光束14、该第二光束24、该第三光束32以及该第四光束46为高分辨像素光。
复参阅图1至图3，在本实施例中，该照明模块10发射该第一光束14，经该反射装置20的该反射面22接收后，反射出该第二光束24。而该光偏转装置30设置于该第二光束24的路径上，该光偏转装置30为数字微型反射镜(digital micromirror device；DMD)，其接收该第二光束24后反射出该第三光束32；其中，该第三光束32所形成的一第二发散角β2(35度至55度)。该投射模块40设置于该第三光束32的路径上，其该入射面42接收该第三光束32后，经过该至少一第二透镜本身的结构作用，而由该出射面44投射该第四光束46，自此完成本发明反射照明系统的工作方式。该照明模块10与该反射装置20设置于该投射模块40的该光轴50所在该水平面54的不同侧，且该照明模块10与该反射装置20均不在该第三光束32所形成的扇形照射面积内，避免了光源的遮挡，同时亦提高了光源利用率。
在本发明的第二实施例中，请继续参阅图4A及图4B，其为本发明的反射照明系统的第二实施例的主视图。如图所示，本实施例与第一实施例的差异在于，本实施例该反射装置20中心点到该照明模块10前端位置中心点的一第一距离a为15～40mm，该光偏转装置30与该投射模块40间距离为一第二距离b，该投射模块40的直径为一第三距离c，该第二距离b与该第三距离c的比为0.6～1.5；其中，该第二距离b为30～45mm，该第三距离c为35～50mm。本发明的第二实施例通过限定该第二距离b及该第三距离c的关系，达到最佳的出光率，并且实现良好的空间利用，本发明的第二实施例中其他元件的设置与第一实施例相同，因此不再赘述。
在本案第三实施例中，请参阅图5及图6，其为本发明的反射照明系统的第三实施例的主视图及部分左视图(省略了该光偏转装置30)，如图所示，本实施例与前述实施例不同的处在于，前述实施例的该照明模块10设置于该光轴50所在该铅垂面56上；而本实施例该照明模块10设置于该光轴50所在该铅垂面56的一侧，也就是说，该照明模块10可以设置在该铅垂面56的左侧或右侧，在本实施例中，仅以设置在右侧为例。该出光部12产生的该第一光束14与该光轴50的一铅垂线(图式未示出)形成一夹角γ，该夹角γ为10度，进而反射出该第二光束24，其错位设置能够满足不同状况下的装配，提高装配适应性。本实施例中其他结构与第一实施例相同，故不再赘述。
在本案第四实施例中，请参阅图7及图8，其为本发明的照明系统的第四实施例的主视图及部分左视图(省略了该光偏转装置30)，如图所示，本实施例与第二实施例不同之处在于，第二实施例的该照明模块10与该反射装置20分别设置于该投射模块40的该光轴50的同一径向平面52上；而本实施例该照明模块10与该反射装置20分别设置 于该投射模块40的该光轴50的不同径向平面上，也就是说，该照明模块10设置于该径向平面52上，该反射装置20设置于另一径向平面58上，该径向平面58位于该径向平面52左侧或右侧，在本实施例中以右侧为例。该出光部12产生的该第一光束14与该光轴50的一铅垂线(图式未示出)形成一夹角γ，该夹角γ为10度，其错位设置能够满足不同状况下的装配。本实施例中其他结构与第一实施例相同，故不再赘述。
在本案第五实施例中，请参阅图9及图10，其为本发明的照明系统的第五实施例的主视图及部分左视图(省略了该光偏转装置30)，如图所示，本实施例与第二实施例不同之处在于，第二实施例的该照明模块10设置于该光轴50所在该铅垂面56上，该照明模块10与该反射装置20分别设置于该投射模块40的该光轴50的同一径向平面52上；而本实施例该照明模块10设置于该光轴50所在该铅垂面56的一侧，且该照明模块10与该反射装置20分别设置于该投射模块40的该光轴50的不同径向平面上，如第三实施例及第四实施例的偏转设置。该出光部12产生该第一光束14与该光轴50的一铅垂线(图式未示出)形成一夹角γ，该夹角γ为10度。换言之，本发明第三至五实施例的该照明模块10的该夹角γ能够相对于该铅垂线的三维空间(前、后、左、右等)倾斜，目的在于错位设置能够满足不同状况下的装配。本实施例中其他结构与第一实施例相同，故不再赘述。
综上所述，本发明的反射照明系统借由将照明模块10与反射装置20分别设置于光轴50的水平面54的不同侧，合理利用了车灯装配的狭小空间，通过设置照明模块10与反射装置20的相对设置关系；或借由光偏转装置30与投射模块40依照一定比例设置，减小了反射照明系统整体所占用的空间，与熟知技术相比，本案的反射照明系统能够完成DMD投影模块的装配，实现合理的空间利用。
故本发明实为一具有新颖性、创造性及可供产业上利用者，应符合专利法专利申请要件无疑，爰依法提出发明专利申请，祈钧局早日赐准专利，至感为祷。
惟以上所述者，仅为本发明的较佳实施例而已，并非用来限定本发明实施的范围，举凡依本发明权利要求范围所述的形状、构造、特征及精神所为的均等变化与修饰，均应包括于本发明的权利要求范围内。
