而现有的光学系统采用的是多套光源模组和光学镜片组的结构，例如，其中一套光源模组和光学镜片组用于实现照明功能，另一套光源模组和光学镜片组用于实现投影功能，结果导致光学系统的硬件成本高，且占用空间大。
发明内容
本申请实施例提供一种光源装置以及光学系统。
根据本申请的第一方面，本申请实施例提供一种光源装置，该光源装置包括激发光模组、荧光模组、补充光模组、合光件以及中继模组。其中，激发光模组包括激发光光源、第一整形单元和第二整形单元，激发光光源用于产生第一激发光；第一整形单元和第二整形单元中的其中一个可选择地位于第一激发光所在的光路上，用于对第一激发光进行光学整形，以产生第二激发光；第一整形单元和第二整形单元分别产生的第二激发光的光斑能量分布情况不相同。荧光模组设置在第二激发光所在的光路上，用于在第二激发光的激发下产生指定荧光；补充光模组用于产生补充光，补充光所在的波长区间和指定荧光所在的波长区间不重合；合光件可活动地设置在指定荧光所在的光路上；在第一整形单元位于第一激发光所在光路的情况下，光源装置适于工作在照明模式，合光件位于指定荧光所在的光路上，并用于对补充光和指定荧光进行合光，以产生入射至中继模组的指定光线；在第二整形单元位于第一激发光所在光路的情况下，光源装置适于工作在投影模式，合光件偏离于指定荧光所在的光路，以使指定荧光直接入射至中继模组。
根据本申请的第二方面，本申请实施例还提供一种光学系统，该光学系统包括上述的光源装置以及光调制器。其中，光源装置用于产生指定合光。光调制器设置在指定合光所在的光路上。
本申请实施方式提供了一种光源装置以及光学系统，该光源装置包括激发光模组、荧光模组、补充光模组、合光件以及中继模组。其中，激发光模组包括激发光光源、第一整形单元和第二整形单元，激发光光源用于产生第一激发光；第一整形单元和第二整形单元中的其中一个可选择地位于第一激发光所在的光路上，其用于对第一激发光进行光学整形，以产生第二激发光；第一整形单元和第二整形单元分别产生的第二激发光的光斑能量分布情况不相同。
具体而言，不同的光斑能量分布情况可以对应于光源装置所能够实现的不同光学功能。因此，光源装置通过对第一整形单元和第二整形单元进行切换，可以改变第二激发光的光斑能量分布情况，进而实现不同的光学功能。例如，第一整形单元可以对应于照明功能，则第一整形单元可以将第一激发光整形成满足法规规定的光斑(例如，中间亮且四周暗的光斑)。而第二整形单元可以对应于投影功能，则第二整形单元可以将第一激发光整形成能量均匀分布的光斑，以保证投影图像的显示质量。
本申请中的第一整形单元和第二整形单元通过共用同一路第一激发光可以实现两种不同的光斑能量分布，使得光学系统中仅需设置一个光源装置就可以实现两种不同的光学功能。在一方面，可以降低光学系统的硬件成本；在另一方面，可以减小光学系统的占用空间，实现光学系统的小型化设计。
进一步地，合光件可活动地设置在荧光模组在第二激发光的激发下产生的指定荧光所在的光路上，以使合光件能够与第一整形单元和第二整形单元中的其中一个协同进行工作，进而使得光源装置能够实现两种具有不同特性的模式。
具体而言，当第一整形单元位于第一激发光所在的光路上且合光件位于指定荧光所在的光路上时，第二激发光的光斑能量可以大致呈中间亮且四周暗的分布状态。此时，合光件对指定荧光和补充光模组产生的补充光进行合光，以产生入射至中继模组的指定光线。由于补充光所在的波长区间和指定荧光所在的波长区间不重合，因此，补充光的加入可以弥补指定荧光存在的光谱窄的问题，使得指定光线的整体光谱变得连续平缓，以提高光源装置的显色指数，可以满足照明领域高显色指数的应用需求。在这种情况下，光源装置能够实现高显色指数的照明模式。
当第二整形单元位于第一激发光所在的光路上且合光件偏离于指定荧光所在的光路时，第二激发光的光斑能量可以大致呈均匀分布状态。此时，指定荧光直接入射至中继模组。在这种情况下，由于合光件不位于指定荧光所在的光路上，使得指定荧光不会出现因透射合光件而造成的能量损失问题，可以提高指定荧光的整体亮度，以使得投影图像具有更好的显示质量。在这种情况下，光源装置能够实现高亮度的投影模式。
这里需要说明的是，当光源装置应用在配置有光调制器的光学系统中时，若光源装置处于“照明模式”，则光调制器用于对光源装置产生的指定合光进行反射，且在反射过程中不会对该指定合光进行调制。若光源装置处于“投影模式”，则光调制器用于对光源装置产生的指定合光进行调制，以产生携带有图像信息的光线。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，本申请实施方式提供一种光学系统100，该光学系统100能够实现多种光学功能，例如，照明功能、投影功能等等。具体地，该光学系统100可以安装在车辆的车灯上，在车辆处于行驶情况下，光学系统100可以实现照明功能；在车辆处于停车情况下，光学系统100可以实现投影功能，以丰富车灯的使用场景。当然，光学系统100也可以应用于其他具有照明功能的设备中，本申请不作具体限定。
在本实施例中，光学系统100可以包括光源装置200以及光调制器120。其中，光源装置200用于产生指定合光LD，这里的“指定合光LD”可以是激光和荧光的混合光线，也可以是LED光和荧光的混合光线，还可以是激光、LED光和荧光的混合光线。
本实施例中的光源装置200能够改变指定合光LD对应光斑的能量分布情况，以实现不同的光学功能。例如，当光学系统100需要实现照明功能(也即，光学系统100工作在照明模式)时，光源装置200可以将光斑整形成“中间亮且四周暗”的非均匀能量分布的光斑。
请分别参阅图2和图3，图2示出的是满足法规要求的远光照明模式下的光斑能量分布示意图，图3示出的是满足法规要求的近光照明模式下的光斑能量分布示意图。在光源装置200将光斑整形成如图2所示的非均匀能量分布的光斑的情况下，光学系统100工作在远光照明模式；在光源装置200将光斑整形成如图3所示的非均匀能量分布的光斑的情况下，光学系统100工作在近光照明模式。
这里不难发现，近光照明模式和远光照明模式下所对应的光斑能量分布均是呈“中间强，四周弱”非均匀分布，两者的区别在于光斑的整体形状不相同。在一些可能的实施例中，在光源装置200中可以设置有第一光斑整形件和第二光斑整形件(例如，第一光斑整形件和第二光斑整形件可以分别是不同形状的遮光片)，第一光斑整形件和第二光斑整形件可选择地设置在光源装置200中的光路上，这里的“光路”可以是第一激发光J1所在的光路，也可以是指定合光LD所在的光路。具体地，当光学系统100工作在近光照明模式时，可以将第一光斑整形件移动至光源装置200中的光路上，以使光斑的形状满足近光照明的法规要求；当光学系统100工作在远光照明模式时，可以将第二光斑整形件移动至光源装置200中的光路上，以使光斑的形状满足远光照明的法规要求。因此，本实施例通过设置第一光斑整形件和第二光斑整形件可以使得光学系统100在远光照明模式和近光照明模式之间灵活切换，丰富了车灯的应用场景。
当光学系统100需要实现投影功能时(也即，光学系统100工作在投影模式)，光源装置200可以将光斑整形成均匀能量分布的光斑，以保证投影图像的显示质量。具体地，关于光源装置200的具体实现方式以及指定合光LD的具体产生方式在说明书后文中进行介绍。
光调制器120设置在指定合光LD所在的光路上，其用于对指定合光LD进行引导。具体地，当光学系统100需要实现照明功能时，光调制器120用于直接将指定合光LD反射至待照明区域(例如，车辆的前后方区域)；当光学系统100需要实现投影功能时，光调制器120用于对指定合光LD进行调制，以产生携带有图像信息的光线，并将携带有图像信息的光线反射至待投影区域(例如，投影幕布、墙面等等)。
具体地，光调制器120可以为数字微镜器件(Digital Micromirror Devices,DMD)，DMD由数字微镜阵列构成，每一数字微镜构成一个调制单元，一个调制单元用于调制一个像素对应的图像。各数字微镜在控制器件产生的驱动信号的驱动下进行翻转，各数字微镜的翻转的次数由驱动信号决定，翻转的数字微镜阵列对指定合光LD进行调制，以形成携带有图像信息的光线。在另一些可能的实施例中，光调制器120还可以是HTPS-LCD显示芯片、液晶覆硅芯片(Liquid Crystal on Silicon,LCoS)等等，本实施例对光调制器120的具体实现方式不作限定。
请参阅图4，光源装置200可以包括激发光模组10、荧光模组30、补充光模组50、合光件70以及中继模组90。其中，激发光模组10可以包括激发光光源120、第一整形单元140和第二整形单元160，激发光光源120用于产生第一激发光J1，第一整形单元140和第二整形单元160中的其中一个可选择地位于第一激发光J1所在的光路上，其用于对第一激发光J1进行光学整形，以产生第二激发光J2。具体地，第一整形单元140和第二整形单元160分别产生的第二激发光J2的光斑能量分布情况不相同。
具体而言，不同的光斑能量分布情况可以对应于光源装置200所能够实现的不同光学功能。因此，光源装置200通过对第一整形单元140和第二整形单元160进行切换，可以改变第二激发光J2的光斑能量分布情况，进而实现不同的光学功能。例如，第一整形单元140可以对应于照明功能，则第一整形单元140可以将第一激发光J1整形成满足法规规定的照明光斑(例如，如图2和图3所示的中间亮且四周暗的光斑)。而第二整形单元160可以对应于投影功能，则第二整形单元160可以将第一激发光J1整形成能量均匀分布的光斑，以保证投影图像的显示质量。
本申请中的第一整形单元140和第二整形单元160通过共用同一路第一激发光J1可以实现两种不同的光斑能量分布，使得光学系统100中仅需设置一个光源装置200就可以实现两种不同的光学功能。在一方面，可以降低光学系统100的硬件成本；在另一方面，可以减小光学系统100的占用空间，实现光学系统100的小型化设计。
荧光模组30设置在第二激发光J2所在的光路上，其用于在第二激发光J2的激发下产生指定荧光F。补充光模组50用于产生补充光S，补充光S所在的波长区间和指定荧光F所在的波长区间不重合。例如，指定荧光F可以位于蓝绿光所在的波段，补充光S可以位于红光所在的波段。
合光件70可活动地设置在指定荧光F所在的光路上，以使合光件70能够与第一整形单元140和第二整形单元160中的其中一个协同进行工作，进而使得光源装置200能够实现两种具有不同特性的模式。
具体而言，当第一整形单元140位于第一激发光J1所在的光路上且合光件70位于指定荧光F所在的光路上时，第二激发光J2的光斑能量可以大致呈中间亮且四周暗的分布状态。此时，合光件70用于对补充光S和指定荧光F进行合光，以产生入射至中继模组90的指定光线L。由于补充光S所在的波长区间和指定荧光F所在的波长区间不重合，因此，补充光S的加入可以弥补指定荧光F存在的光谱窄的问题，使得指定光线L的整体光谱变得连续平缓，以提高光源装置200的显色指数，可以满足照明领域高显色指数的应用需求。在这种情况下，光源装置200能够实现高显色指数的照明模式。
当第二整形单元160位于第一激发光J1所在的光路上且合光件70偏离于指定荧光F所在的光路时，第二激发光J2的光斑能量可以大致呈均匀分布状态。此时，指定荧光F直接入射至中继模组90。在这种情况下，由于合光件70不位于指定荧光F所在的光路上，使得指定荧光F不会出现因透射合光件70而造成的能量损失问题，可以提高指定荧光F的整体亮度，以使得投影图像具有更好的显示质量。在这种情况下，光源装置200能够实现高亮度的投影模式。
这里需要说明的是，当光源装置200应用在配置有光调制器120的光学系统100中时，若光源装置200处于“照明模式”，则光调制器120用于对光源装置200产生的指定合光LD进行反射，且在反射过程中不会对该指定合光LD进行调制。若光源装置200处于“投影模式”，则光调制器120用于对光源装置200产生的指定合光LD进行调制，以产生携带有图像信息的光线。
下面对光源装置200的具体实现方式进行介绍。
在本实施例中，激发光模组10用于产生第二激发光J2并调整第二激发光J2的光斑能量分布情况。激发光模组10可以包括激发光光源120、第一整形单元140和第二整形单元160。其中，激发光光源120用于产生第一激发光J1。具体地，第一激发光J1为蓝光。因此，经过第一整形单元140或第二整形单元160整形出射的第二激发光J2同样为蓝光。
在一些可能的实施例中，激发光光源120可以是激光发生器，则第一激发光J1为蓝激光。具体地，激光发生器可以集成有多个蓝激光芯片，以提升蓝激光的亮度。在另一些可能的实施例中，激发光光源120可以是LED光发生器，则第一激发光J1为蓝LED光。具体地，LED光发生器可以集成有多个蓝色LED灯珠，以提升蓝LED光的亮度。
在本实施例中，第一整形单元140可选择地位于第一激发光J1所在的光路上，其用于对第一激发光J1的光斑进行整形。具体地，第一整形单元140所产生的第二激发光J2的光斑能量分布情况可以为：第二激发光J2的光斑中心的能量强度大于光斑边缘的能量强度。因此，当第一整形单元140切换至第一激发光J1所在的光路上时，光源装置200能够实现照明功能。具体而言，第二激发光J2的光斑能量可以从光斑中心到四周依次减弱；也可以在能量减弱的过程中，有一段能量增加的趋势。具体地，研发人员可以根据照明功能对应的光型需求去对第一激发光J1的光斑进行整形，以满足远近光照明的法规要求。
在一些可能的实施例中，请参阅图5，第一整形单元140可以包括高斯散射片1410，由于经由高斯散射片1410处出射光线的光强能够呈高斯分布，因此，第二激发光J2的光斑能量可以呈中间强四周弱的非均匀分布。具体地，在光源装置200工作在照明模式的情况下，高斯散射片1410位于第一激发光J1所在的光路上，其用于对第一激发光J1进行高斯散射。
在图5所示的实施例中，第一整形单元140还可以包括凸透镜1430和凹透镜1450，高斯散射片1410、凸透镜1430和凹透镜1450依次间隔排列以共同形成第一整形单元140。当第一整形单元140切换至第一激发光J1所在的光路上时，高斯散射片1410、凸透镜1430和凹透镜1450依次位于第一激发光J1所在的光路上。具体地，凸透镜1430和凹透镜1450用于对高斯散射片1410散射后的光线按预设的角度分布进行整形，以使第二激发光J2能够满足预设的角分布。在一些可能的实施例中，激发光光源120可以集成有多个蓝激光芯片，使得第一激发光J1的光斑呈椭圆状的长条形。在这种情况下，凸透镜1430可以是凸柱透镜，凹透镜1450可以是凹柱透镜。
在其他一些可能的实施例中，凸透镜1430和凹透镜1450可以由其他的光学元件替代，以对高斯散射片1410散射后的光线进行角分布调整。例如，凸透镜1430和凹透镜1450可以由一个弯月透镜(图中未示出)替代，该弯月透镜的凸面朝向高斯散射片1410设置，弯月透镜的凹面用于出射第二激发光J2，以使得第一整形单元140的整体结构更加紧凑。
在本实施例中，第二整形单元160可选择地位于第一激发光J1所在的光路上，其用于对第一激发光J1的光斑进行整形。具体地，第二整形单元160所产生的第二激发光J2的光斑能量分布情况为：从第二激发光J2的光斑中心到光斑边缘，能量强度均匀分布。因此，当第二整形单元160切换至第一激发光J1所在的光路上时，光源装置200能够实现投影功能。
在图5所示的实施例中，第二整形单元160可以包括匀光件1610，在光源装置200工作在投影模式的情况下，匀光件1610位于第一激发光J1所在的光路上。具体地，匀光件1610用于对第一激发光J1进行匀光，以使第二激发光J2的光斑能量能够均匀分布。如图5所示，匀光件1610可以是复眼透镜。在另一些可能的实施例中，匀光件1610也可以是匀光棒(例如，方棒)。在又一些可能的实施例中，第二整形单元160中可以设置散射片(例如，朗伯散射片)来代替匀光件1610实现对光斑的匀化。
这里需要说明的是，在现有技术中，光学系统100在进行投影显示时，通常会在荧光轮和光调制器之间设置有匀光件(例如，复眼透镜)，以实现图像光的均匀显示。而本申请中，由于照明光路和图像投影光路共用荧光轮和光调制器之间的光路，如果在荧光轮和光调制器之间设置有匀光件以实现均匀的投影显示，会导致照明光路非均匀的能量分布被匀化，以致无法满足法规所需的非均匀光斑。因此，本申请将图像投影光路中的匀光件设置于第二整形单元160内，以提高图像光的亮度均匀性，同时避免对照明光路造成影响。
在本实施例中，激发光模组10还可以包括运动平台180，第一整形单元140和第二整形单元160安装于运动平台180。第一整形单元140和第二整形单元160的其中一个在运动平台180的带动下运动至第一激发光J1所在的光路上。具体地，运动平台180可以用于带动第一整形单元140和第二整形单元160沿指定方向X移动，以使第一整形单元140和第二整形单元160中的其中一个移动至第一激发光J1所在的光路上，以实现对第一整形单元140和第二整形单元160进行切换。这里的“指定方向X”可以垂直于第一激发光J1所在的光路。具体地，运动平台180可以包括安装座(图中未示出)和直线驱动结构(图中未示出)。其中，安装座用于固定第一整形单元140和第二整形单元160，直线驱动结构与安装座传动连接，其用于带动安装座沿指定方向X移动。例如，直线驱动结构可以是丝杆螺母结构、齿轮齿条结构等等。
当然，在其他一些可能的实施例中，运动平台180可以用于带动第一整形单元140和第二整形单元160绕指定中心O转动，以使第一整形单元140和第二整形单元160中的其中一个转动至第一激发光J1所在的光路上，以实现对第一整形单元140和第二整形单元160进行切换。具体地，运动平台180可以包括安装座(图中未示出)和旋转驱动结构(图中未示出)。其中，安装座用于固定第一整形单元140和第二整形单元160，旋转驱动结构与安装座传动连接，其用于带动安装座绕指定中心O转动。例如，旋转驱动结构可以是旋转电机、旋转舵机等等。
在一些可能的实施例中，激发光模组10还可以包括中继透镜190，中继透镜190设置在第二激发光J2所在的光路上。在一方面，对于第一整形单元140出射的第二激发光J2而言，中继透镜190可以将满足预设角分布的第二激发光J2转换成满足预设面分布的第二激发光J2后，入射至荧光模组30。也即，这里的中继透镜190起到“角面转换”的作用。在另一方面，对于第二整形单元160出射的第二激发光J2而言，中继透镜190可以起到会聚收集第二激发光J2的作用，以提高第二激发光J2的能量利用效率。具体地，中继透镜190可以是凸透镜，中继透镜190的数量可以是一个或多个，本实施例对此不作限定。
在本实施例中，荧光模组30用于在第二激发光J2的激发下产生指定荧光F。请参阅图4和图6，荧光模组30可以包括荧光轮320，荧光轮320包括相连接的荧光部3210和引导部3230。荧光部3210和引导部3230关于荧光轮320的旋转中心M环绕设置，以使在荧光轮320旋转的过程中，荧光部3210和引导部3230会依次循环位于第二激发光J2所在的光路上。具体地，荧光部3210用于在第二激发光J2的激发下产生指定荧光F，引导部3230用于对第二激发光J2进行引导以形成第三激发光J3，这里的“引导”可以是对第二激发光J2进行透射、反射等光学操作，因此，在第二激发光J2为蓝光的情况下，引导部3230所形成的第三激发光J3同样为蓝光。
这里需要说明的是，在第一整形单元140位于第一激发光J1所在光路的情况下，合光件70还位于第三激发光J3所在的光路上，并用于对补充光S、指定荧光F和第三激发光J3进行合光，以产生指定光线L。也就是说，在光源装置200工作在照明模式的情况下，光源装置200产生的指定合光LD是补充光S、指定荧光F和第三激发光J3三者的混合光(也即，指定光线L)。在第二整形单元160位于第一激发光J1所在光路的情况下，合光件70还偏离于第三激发光J3所在的光路，以使第三激发光J3直接入射至中继模组90。也就是说，在光源装置200工作在投影模式的情况下，光源装置200产生的指定合光LD是第三激发光J3与指定荧光F的混合光。
在一些可能的实施例中，光源装置200还可以包括驱动件(图中未示出)，驱动件与合光件70传动连接。在光源装置200工作在照明模式的情况下，驱动件用于带动合光件70运动至补充光S、指定荧光F和第三激发光J3所在的光路上。在光源装置200工作在投影模式的情况下，驱动件用于带动合光件70运动以使合光件70偏离指定荧光F和第三激发光J3所在的光路，以使合光件70不位于指定荧光F和第三激发光J3所在的光路。
具体地，驱动件可以是直线驱动件，例如，丝杆螺母结构、齿轮齿条结构等等。合光件70在直线驱动件的带动下可以沿预设方向Y移动。在一些可能的实施例中，预设方向Y和指定方向X同向，合光件70可以固定在运动平台180上，此时，这里的“直线驱动件”与上文中的直线驱动结构为同一结构。运动平台180带动合光件70、第一整形单元140和第二整形单元160同步移动，以节省光源装置200的硬件成本，提高光源装置200的整体集成度。
在本实施例中，补充光模组50用于产生补充光S，补充光S所在的波段可以根据指定荧光F所在的波段进行确定。例如，在指定荧光F中缺少红光分量的情况下，补充光S可以是红光。具体地，关于补充光S的具体颜色在下文实施例中进行详细介绍。
请再次参阅图4，补充光模组50可以包括补充光光源520和第一收集透镜540。其中，补充光光源520用于产生补充光S。在一些可能的实施例中，补充光光源520可以是激光发生器，则补充光S为激光。具体地，激光发生器可以集成有多个激光芯片，以提升补充光S的亮度。在另一些可能的实施例中，补充光光源520可以是LED光发生器，则补充光S为LED光。具体地，LED光发生器可以集成有多个LED灯珠，以提升补充光S的亮度。
这里需要说明的是，在补充光S为LED光的情况下，补充光S的光谱能够更宽(这里相较于补充光S为激光而言)。因此，在利用补充光S进行补光的情况下，可以解决指定荧光F在短波段或长波段光谱较窄的问题。例如，在补充光S为红LED光的情况下，红LED光几乎可以覆盖红光所在的波段，以使得合光后的指定光线L在长波段(例如，红光所在的波段)的光谱变得连续，以提高指定光线L的显色指数。
第一收集透镜540设置在补充光S所在的光路上，其用于对补充光S进行收集，以提高对补充光S的能量利用效率。具体地，第一收集透镜540可以是凸透镜，第一收集透镜540的数量可以是一个或多个，本实施例对此不作限定。
在本实施例中，指定光线L的波段可以覆盖红光、橙光、黄光、绿光和蓝光所在的波段。因此，在照明模式下，光源装置200所产生的光线从绿段到红段能量分布更符合太阳光谱特性，以实现更高质量的显色指数照明。
下面对荧光轮320、补充光模组50和合光件70的具体实现方式进行介绍。
请参阅图7和图8，荧光轮320可以为第一透射式荧光轮321，第一透射式荧光轮321用于透射指定荧光F。具体地，荧光部3210的数量可以为多个，多个荧光部3210可以包括第一橙荧光部301、第一黄荧光部302和第一绿荧光部303，引导部3230可以为第一蓝光透射部304。其中，第一橙荧光部301、第一黄荧光部302、第一绿荧光部303和第一蓝光透射部304相连接。例如，第一橙荧光部301、第一黄荧光部302、第一绿荧光部303和第一蓝光透射部304可以依次邻接，且关于第一透射式荧光轮321的旋转中心M1环绕设置。
在第一透射式荧光轮321旋转的过程中，第一橙荧光部301、第一黄荧光部302、第一绿荧光部303和第一蓝光透射部304会依次循环位于第二激发光J2所在的光路上。具体地，第一橙荧光部301用于在第二激发光J2的激发下产生第一橙荧光，第一黄荧光部302用于在第二激发光J2的激发下产生第一黄荧光，第一绿荧光部303用于在第二激发光J2的激发下产生第一绿荧光。也就是说，本实施例中的指定荧光F为第一橙荧光部301产生的第一橙荧光、第一黄荧光部302产生的第一黄荧光和第一绿荧光部303产生的第一绿荧光在时域上的混合光。第一蓝光透射部304用于透射第二激发光J2，以使第二激发光J2经由第一蓝光透射部304发生透射，以形成第三激发光J3。因此，在第一透射式荧光轮321旋转的过程中，会依次循环出射橙光、黄光、绿光和蓝光。本实施例通过在第一透射式荧光轮321上设置第一橙荧光部301和第一黄荧光部302，使得后续合成的指定光线L中包括橙光分量和黄光分量，以使指定光线L的整体光谱变得连续平缓。
在本实施例中，补充光S为红光(例如，红激光、红LED光)。合光件70可以为第一合光膜片720。具体地，在第一整形单元140位于第一激发光J1所在光路的情况下，第一合光膜片720位于补充光S、指定荧光F和第三激发光J3所在的光路上，其用于反射补充光S、并透射指定荧光F和第三激发光J3，以产生指定光线L。示例性地，第一合光膜片720可以是反红透黄膜片。例如，第一合光膜片720可以反射波长大于600nm地光线并透射波长小于或等于600nm的光线。在第二整形单元160位于第一激发光J1所在光路的情况下，第一合光膜片720偏离指定荧光F和第三激发光J3所在的光路。
这里不难理解的是，本实施例采用的是波长合光的合光方式，由于第一合光膜片720无法实现对指定荧光F进行完全透射，使得第一绿荧光和第一黄荧光的能量会出现部分损失，此时，在将红光(也即，补充光S)进行合光的情况下，得到的指定光线L的光谱在绿段到红段能量分布更符合太阳光谱特性，长波段光谱连续平缓，从而提高光源装置200在照明模式下的显色指数。此外，在光源装置200处于投影模式时，第一绿荧光和第一黄荧光不会出现因透射第一合光膜片720而出现部分能量损失的问题，以提高指定荧光F的整体亮度。
在一些可能的实施例中，荧光模组30还可以包括第二收集透镜322，第二收集透镜322设置在第一透射式荧光轮321和第一合光膜片720之间，且位于指定荧光F和第三激发光J3所在的光路上，其用于对指定荧光F和第三激发光J3进行收集，以提高对指定荧光F和第三激发光J3的能量利用效率。具体地，第二收集透镜322可以是凸透镜，第二收集透镜322的数量可以是一个或多个，本实施例对此不作限定。
请参阅图9和图10，荧光轮320可以为第二透射式荧光轮323，第二透射式荧光轮323用于透射指定荧光F。具体地，荧光部3210的数量可以为多个，多个荧光部3210可以包括第一红荧光部305、第二橙荧光部306、第二黄荧光部307和第二绿荧光部308，引导部3230可以为第二蓝光透射部309。其中，第一红荧光部305、第二橙荧光部306、第二黄荧光部307、第二绿荧光部308和第二蓝光透射部309相连接。例如，第一红荧光部305、第二橙荧光部306、第二黄荧光部307、第二绿荧光部308和第二蓝光透射部309可以依次邻接，且关于第二透射式荧光轮323的旋转中心M2环绕设置。
在第二透射式荧光轮323旋转的过程中，第一红荧光部305、第二橙荧光部306、第二黄荧光部307、第二绿荧光部308和第二蓝光透射部309会依次循环位于第二激发光J2所在的光路上。具体地，第一红荧光部305用于在第二激发光J2的激发下产生第一红荧光，第二橙荧光部306用于在第二激发光J2的激发下产生第二橙荧光，第二黄荧光部307用于在第二激发光J2的激发下产生第二黄荧光，第二绿荧光部308用于在第二激发光J2的激发下产生第二绿荧光。也就是说，本实施例中的指定荧光F为第一红荧光部305产生的第一红荧光、第二橙荧光部306产生的第二橙荧光、第二黄荧光部307产生的第二黄荧光和第二绿荧光部308产生的第二绿荧光在时域上的混合光。第二蓝光透射部309用于透射第二激发光J2，以使第二激发光J2经由第二蓝光透射部309发生透射，以形成第三激发光J3。因此，在第二透射式荧光轮323旋转的过程中，会依次循环出射红光、橙光、黄光、绿光和蓝光。本实施例通过在第二透射式荧光轮323上设置第二橙荧光部306和第二黄荧光部307，使得后续合成的指定光线L中包括橙光分量和黄光分量，以使指定光线L的整体光谱变得连续平缓。
在本实施例中，补充光S为蓝光。这里需要说明的是，本实施例中的补充光S所在的至少部分波长区间和第一激发光J1所在的波长区间不重合。由于为了提高指定荧光F的激发效率，第一激发光J1通常采用的是蓝激光，使得在指定光线L中，会出现蓝光分量对应的光谱较窄的问题。因此，本实施例通过对蓝光进行补光，可以使得合光后的指定光线L在短波段(例如，蓝光所在的波段)的光谱变得连续，以提高指定光线L的显色指数。
在一些可能的实施例中，补充光S可以为蓝激光，且补充光S对应的中心波长和第一激发光J1对应的中心波长不相同。例如，第一激发光J1的中心波长可以为455nm，补充光S的中心波长可以为445nm、465nm等等。在另一些可能的实施例中，补充光S为宽光谱光源，该宽光谱光源所在的波长区间可以覆盖第一激发光J1所在的波长区间，例如，补充光S可以为蓝LED光。
合光件70可以为第二合光膜片740。具体地，在第一整形单元140位于第一激发光J1所在光路的情况下，第二合光膜片740位于补充光S、指定荧光F和第三激发光J3所在的光路上，其用于反射补充光S，并透射指定荧光F和第三激发光J3，以产生指定光线L。示例性地，第二合光膜片740可以采用波长合光的方式。例如，在第一激发光J1的中心波长为455nm，且补充光S的中心波长为445nm的情况下，第二合光膜片740具体用于反射波长小于450nm的光线并透射波长大于或等于450nm的光线。第二合光膜片740也可以采用区域合光的方式，关于区域合光的具体实现方式可以参考下文中关于第三合光膜片760的相关介绍。
在一些可能的实施例中，荧光模组30还可以包括第三收集透镜324，第三收集透镜324设置在第二透射式荧光轮323和第二合光膜片740之间，且位于指定荧光F和第三激发光J3所在的光路上，其用于对指定荧光F和第三激发光J3进行收集，以提高对指定荧光F和第三激发光J3的能量利用效率。具体地，第三收集透镜324可以是凸透镜，第三收集透镜324的数量可以是一个或多个，本实施例对此不作限定。
请参阅图11和图12，荧光轮320可以为反射式荧光轮325，反射式荧光轮325用于反射指定荧光F。具体地，荧光部3210的数量可以为多个，多个荧光部3210可以包括第二红荧光部311、第三橙荧光部312、第三黄荧光部313和第三绿荧光部314，引导部3230可以为蓝光反射部315。其中，第二红荧光部311、第三橙荧光部312、第三黄荧光部313、第三绿荧光部314和蓝光反射部315相连接。例如，第二红荧光部311、第三橙荧光部312、第三黄荧光部313、第三绿荧光部314和蓝光反射部315可以依次邻接，且关于反射式荧光轮325的旋转中心M3环绕设置。
在反射式荧光轮325旋转的过程中，第二红荧光部311、第三橙荧光部312、第三黄荧光部313、第三绿荧光部314和蓝光反射部315会依次循环位于第二激发光J2所在的光路上。具体地，第二红荧光部311用于在第二激发光J2的激发下产生第二红荧光，第三橙荧光部312用于在第二激发光J2的激发下产生第三橙荧光，第三黄荧光部313用于在第二激发光J2的激发下产生第三黄荧光，第三绿荧光部314用于在第二激发光J2的激发下产生第三绿荧光。也就是说，本实施例中的指定荧光F为第二红荧光部311产生的第二红荧光、第三橙荧光部312产生的第三橙荧光、第三黄荧光部313产生的第三黄荧光和第三绿荧光部314产生的第三绿荧光在时域上的的混合光。蓝光反射部315用于反射第二激发光J2，以使第二激发光J2经由蓝光反射部315发生反射，以形成第三激发光J3。因此，在反射式荧光轮325旋转的过程中，会依次循环出射红光、橙光、黄光、绿光和蓝光。本实施例通过在反射式荧光轮325上设置第三橙荧光部312和第三黄荧光部313，使得后续合成的指定光线L中包括橙光分量和黄光分量，以使指定光线L的整体光谱变得连续平缓。
此外，相较于图7和图9中采用透射式荧光轮的方案，本实施例中采用反射式荧光轮，可以解决透射式荧光轮散热差的问题，以提升对荧光的激发效率。当然，图7和图9所示的光源装置200的光路结构简单，适于应用于对光学系统100体积要求严格且散热较好的应用场景。
在本实施例中，补充光S为蓝光，且补充光S所在的至少部分波长区间和第一激发光J1所在的波长区间不重合。具体地，关于补充光S的具体实现方式可以参考上文关于图9所示实施例中补充光S的相关介绍，在此不再赘述。
合光件70可以为第三合光膜片760。具体地，在第一整形单元140位于第一激发光J1所在光路的情况下，第三合光膜片760用于反射补充光S，并透射指定荧光F和第三激发光J3，以产生指定光线。
请参阅图13，第三合光膜片760可以采用区域合光的方式，其可以包括反射区域7610和透射区域7630，透射区域7630和反射区域7610相邻接。具体地，第三合光膜片760可以包括本体(图中未示出)和反射膜(图中未示出)，其中，本体可以是透明材料(例如，玻璃)，反射膜贴设于本体的中央位置，以形成反射区域7610，本体上未贴设有反射膜的区域形成透射区域7630。在第一整形单元140位于第一激发光J1所在光路的情况下，反射区域7610位于补充光S所在的光路上，以反射补充光S；透射区域7630位于指定荧光F和第三激发光J3所在的光路上，以透射指定荧光F和第三激发光J3。在其他一些可能的实施例中，第三合光膜片760也可以采用波长合光的方式，例如，在第一激发光J1的中心波长为455nm，且补充光S的中心波长为445nm的情况下，第二合光膜片740具体用于反射波长小于450nm的光线并透射波长大于或等于450nm的光线。
在图11所示的实施例中，荧光模组30还可以包括第四合光膜片326和反射镜327。其中，第四合光膜片326设置在激发光模组10和反射式荧光轮325之间，且位于第二激发光J2和指定荧光F所在的光路上，其用于将第二激发光J2透射至反射式荧光轮325，并反射指定荧光F。具体地，第四合光膜片326可以是透蓝反红绿膜片。
反射镜327设置在第四合光膜片326背离反射式荧光轮325的一侧，且第四合光膜片326和反射镜327均位于第三激发光J3所在的光路上；第三激发光J3依次经由第四合光膜片326、反射镜327和第四合光膜片326后出射。因此，本实施例中的第四合光膜片326起到对指定荧光F的引导作用，反射镜327起到对第三激发光J3的引导作用，以使后续能够顺利进行合光。
在图11所示的实施例中，荧光模组30还可以包括收集透镜组328，收集透镜组328位于反射式荧光轮325和第四合光膜片326之间，且位于第二激发光J2、指定荧光F和第三激发光J3所在的光路上。收集透镜组328用于对指定荧光F会聚后出射至第四合光膜片326。第二激发光J2经由收集透镜组328折射后入射至反射式荧光轮325，第三激发光J3经由收集透镜组328折射后入射至第四合光膜片326。
在一方面，收集透镜组328可以用于对第二激发光J2、指定荧光F和第三激发光J3进行会聚收集，以提高对第二激发光J2、指定荧光F和第三激发光J3的能量利用效率。具体地，收集透镜组328可以是凸透镜，凸透镜的数量可以是一个或多个，本实施例对此不作限定。在另一方面，收集透镜组328还用于对第二激发光J2进行折射，以使第二激发光J2呈一定角度(非垂直)入射至反射式荧光轮325，以使反射式荧光轮325出射的第三激发光J3所在的光路可以和第二激发光J2所在的光路不重合，使得第三激发光J3能够顺利入射至反射镜327所在的位置。
具体而言，激发光光源120设有出光口1201，出光口1201用于出射第一激发光J1。出光口1201和反射镜327分别位于收集透镜组328的光轴的两侧。因此，本实施例中的出光口1201和反射镜327在空间上是错开设置的，可以避免激发光模组10出射的第二激发光J2入射至反射镜327的情况发生，以保证光源装置200的正常工作。
请再次参阅图4，光源装置200还可以包括控制器560，控制器560和补充光模组50电性连接。在第二整形单元160位于第一激发光J1所在光路的情况下，控制器560用于关闭补充光模组50。具体地，控制器560与补充光光源520电性连接，控制器560可以是微处理器，也可以是集成有控制芯片的控制电路等等。
这里不难发现，在第二整形单元160位于第一激发光J1所在光路的情况下，合光件70偏离于指定荧光F所在的光路，此时，合光件70无法顺利将补充光S顺利引导至中继模组90。在这种情况下，控制器560关闭补充光光源520，以降低光源装置200的能耗。当然，在第一整形单元160位于第一激发光J1所在光路的情况下，控制器560用于开启补充光光源520。
在本实施例中，中继模组90用于将入射的光线引导至指定位置，例如，指定位置可以是光调制器120所在的位置，以使得光调制器120能够顺利进行工作。
在图7所示的实施例中，中继模组90可以包括第一中继透镜910和球面反射镜920。在第一整形单元140位于第一激发光J1所在光路的情况下，第一中继透镜910和球面反射镜920依次设置在指定光线L所在的光路上。第一中继透镜910和球面反射镜920能够起到光斑整形和像差校正的作用，此外，本实施例中的球面反射镜920可以等效为一个光传导面，以使中继模组90中仅需设置一个第一中继透镜910就能够与球面反射镜920组成完整的中继系统，降低了中继模组90的硬件成本，并实现了光源装置200的小型化设计。
在图9所示的实施例中，中继模组90可以包括多个第二中继透镜930和全反射棱镜940。在第一整形单元140位于第一激发光J1所在光路的情况下，多个第二中继透镜930和全反射棱镜940依次设置在指定光线L所在的光路上。具体地，第二中继透镜930的数量可以是两个、三个等等，以满足对光斑整形和像差校正的需求。
此外，相较于图7中采用球面反射镜920的方案，本实施例中的中继模组90通过采用全反射棱镜940对光线进行反射，可以解决球面反射镜920存在的挡光问题，全反射棱镜940还可以降低光线的能量损失，提高能量利用效率。
本实施例提供了一种光源装置200以及配置有光源装置200的光学系统100，其中，光源装置200可以包括激发光模组10、荧光模组30、补充光模组50、合光件70以及中继模组90。其中，激发光模组10可以包括激发光光源120、第一整形单元140和第二整形单元160，激发光光源120用于产生第一激发光J1，第一整形单元140和第二整形单元160中的其中一个可选择地位于第一激发光J1所在的光路上，其用于对第一激发光J1进行光学整形，以产生第二激发光J2。具体地，第一整形单元140和第二整形单元160分别产生的第二激发光J2的光斑能量分布情况不相同。
具体而言，不同的光斑能量分布情况可以对应于光源装置200所能够实现的不同光学功能。因此，光源装置200通过对第一整形单元140和第二整形单元160进行切换，可以改变第二激发光J2的光斑能量分布情况，进而实现不同的光学功能。例如，第一整形单元140可以对应于照明功能，则第一整形单元140可以将第一激发光J1整形成满足法规规定的照明光斑(例如，如图2和图3所示的中间亮且四周暗的光斑)。而第二整形单元160可以对应于投影功能，则第二整形单元160可以将第一激发光J1整形成能量均匀分布的光斑，以保证投影图像的显示质量。
本申请中的第一整形单元140和第二整形单元160通过共用同一路第一激发光J1可以实现两种不同的光斑能量分布，使得光学系统100中仅需设置一个光源装置200就可以实现两种不同的光学功能。在一方面，可以降低光学系统100的硬件成本；在另一方面，可以减小光学系统100的占用空间，实现光学系统100的小型化设计。
荧光模组30设置在第二激发光J2所在的光路上，其用于在第二激发光J2的激发下产生指定荧光F。补充光模组50用于产生补充光S，补充光S所在的波长区间和指定荧光F所在的波长区间不重合。例如，指定荧光F可以位于蓝绿光所在的波段，补充光S可以位于红光所在的波段。
合光件70可活动地设置在指定荧光F所在的光路上，以使合光件70能够与第一整形单元140和第二整形单元160中的其中一个协同进行工作，进而使得光源装置200能够实现两种具有不同特性的模式。
具体而言，当第一整形单元140位于第一激发光J1所在的光路上且合光件70位于指定荧光F所在的光路上时，第二激发光J2的光斑能量可以大致呈中间亮且四周暗的分布状态。此时，合光件70用于对补充光S和指定荧光F进行合光，以产生入射至中继模组90的指定光线L。由于补充光S所在的波长区间和指定荧光F所在的波长区间不重合，因此，补充光S的加入可以弥补指定荧光F存在的光谱窄的问题，使得指定光线L的整体光谱变得连续平缓，以提高光源装置200的显色指数，可以满足照明领域高显色指数的应用需求。在这种情况下，光源装置200能够实现高显色指数的照明模式。
当第二整形单元160位于第一激发光J1所在的光路上且合光件70偏离于指定荧光F所在的光路时，第二激发光J2的光斑能量可以大致呈均匀分布状态。此时，指定荧光F直接入射至中继模组90。在这种情况下，由于合光件70不位于指定荧光F所在的光路上，使得指定荧光F不会出现因透射合光件70而造成的能量损失问题，可以提高指定荧光F的整体亮度，以使得投影图像具有更好的显示质量。在这种情况下，光源装置200能够实现高亮度的投影模式。
