 本发明的最佳实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通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，都属于本发明保护的范围。
正如背景技术所述，现有的采用发光二极管作为的发光光源的车辆用前照灯装置，其发光亮度已经达到极限，若想要再次提高车辆用前照灯装置发光亮度，需要增加发光二极管的个数，但是现有的车辆用前照灯装置的利用空间有限，无法再次增加发光二极管的数量。
基于此，本申请实施例提供了一种照明装置及车辆用前照灯装置，照明装置不但出光亮度高，而且结构简单体积小；此外，照明装置能够通过切换不同透射型波长转换层接收激光，以实现照明装置的不同出光效果，提高了照明装置的灵活性和适应性。为实现上述目的，本申请实施例提供的技术方案如下，具体结合图1至图9所示，对本申请实施例提供的技术方案进行详细的描述。
参考图1所示，为本申请实施例提供的一种照明装置的结构示意图，其中，照明装置包括：

以及，与所述波长转换装置40连接的控制装置50，用于驱动所述波长转换装置40以切换相应透射型波长转换层41接收所述激光。
由上述内容可知，本申请实施例提供的技术方案，照明装置采用激光照射透射型波长转换层后，将得到的受激光以既定方向出射的方式出光，由于激光光源的亮度高，保证了照明装置的出光亮度高；照明装置的结构简单，且其组成的各个组件的体积有限，保证了照明装置的体积较小；通过反射罩和第一基板的半密闭的固定方式，保证将受激光全部出射，避免了光线的浪费；此外，通过控制装置控制波长转换装置以切换不同透射型波长转换层接收激光，以实现照明装置的不同出光效果，提高了照明装置的适用性和灵活性。
当照明装置应用于车辆用前照灯装置中时，需要照明装置发出的光多种多样，其可以为多种形状的光斑，也可为多种颜色的光，为此，本申请提供的照明装置中还可以包括一光整形装置，以对透射型波长转换层发出的受激光进行颜色和/或光斑的整形。具体参考图2所示，为本申请实施例提供的另一种照明装置的结构示意图，其中，在所述波长转换装置40中，所述至少一个透射型波长转换层41朝向所述反射面31一侧相应还设置有一光整形装置60；

另外，照明装置的出光的光斑可以为L形光斑，即，当车辆在双向车道上行驶时，可以将照明装置的出光光斑调整至L形光斑，且L形光斑靠近另一方向车道的部分为近光形式，而远离另一方向车道的部分为远光形式，在保证驾驶员视野的前提下，避免出现灯光照射另一方向车道的行车司机眼睛的情况。即，参考图4a所示，为本申请实施例提供的另一种光阑的结构示意图，所述光阑60的光阑口为L形光阑口；
其中，当包括有所述L形光阑口的光阑，其所对应的透射型波长转换层接收所述激光时，所述L形光阑口的拐角开口朝向所述出光口、且所述L形光阑口的拐角开口处一边的延伸方向与所述光阑至出光口的方向平行。

具体的，结合图4a所示，在当光阑60所对应的透射型波长转换层接收激光时，L形光阑口的拐角开口朝向出光口21、且L形光阑口的拐角开口处一边的延伸方向与光阑60至出光口21的方向X平行的基础上，光阑60的L形光阑口的拐角开口的弯向朝向其右方；以及，参考图4b所示，为图4a所示光阑的照明装置应用于车辆用前照灯时的出光光斑的示意图，其中，当包括有图4a所示光阑的照明装置应用于车辆用前照灯时，其出光光斑61同样呈L形光斑，且L形光斑61的拐角开口弯向超向其右方，提高了车辆用前照灯的灵活性。

需要说明的是，本申请实施例提供的包括有L形光阑口的光阑，能够通过优化其L形光阑口的尺寸等参数，使其出光的L形光斑的弯向部分的面积扩大，保证行车驾驶员的视野大，提高驾驶安全性。如图5e所示，为本申请实施例提供的一种车辆用前照灯的出光光斑的示意图，其L形光斑65的弯向部分面积扩大，在车辆拐弯时保证行车驾驶员的视野大，提高驾驶安全性。
此外，本申请实施例提供的所述光阑的光阑口还可以为条形光阑口；
其中，当包括有所述条形光阑口的光阑，其所对应的透射型波长转换层接收所述激光时，所述条形光阑口的延伸方向与所述光阑至出光口的方向垂直或平行。

进一步的，照明装置的所述光阑的光阑口还覆盖有一滤光片。即，通过滤光片改变照明装置的出光颜色，进一步提高照明装置的适用性和灵活性；其中，当受激光为白光时，滤光片可以为红色滤光片，通过滤光片过滤其他颜色光而通过红光，使得照明装置出光为红光，以作为警示灯起到警示作用；此外，滤光片还可以为其他颜色光的滤光片，对此本申请不做具体限制，需要根据实际应用进行具体设计。
本申请提供的照明装置中，所有透射型波长转换层首尾相对应呈圆环设置，具体参考图6所示，为本申请实施例提供的一种波长转换装置的结构示意图，其中，波长转换装置40包括多个透射型波长转换层41，所有透射型波长转换层41首尾相对应呈圆环设置。
进一步的，参考图7所示，为本申请实施例提供的一种透射型波长转换层的结构示意图，为了提高照明装置的发光效果，还可以在透射型波长转换层41激光入射面镀0度Bluepass膜层41a。进一步的， 0度Bluepass膜层允许入射角小于17度蓝光透射，入射角大于17度的蓝光和所述受激光全部反射。
0度Bluepass膜层减少激光和受激光的逸散损失，保证尽可能多的激光和受激光从透射型波长转换层出射面出射，进一步提高光的利用率，提高照明装置的亮度。
进一步的，参考图7所示，透射型波长转换层41的出射面镀有增透膜41b，以提高透光效果。
其中，本申请实施例提供的控制装置可以包括有一转轴、一电机和一拨档控制器等装置，通过将转轴与波长转换装置的中心处固定，而后通过拨档控制器发送控制信号，以控制电机转动，进而带动波长转换装置转动，来切换不同透射型波长转换层接收激光，而且通过不同透射型波长转换层相应的光整形装置进行整形，提高光照装置的灵活性和适应性。其中，本申请实施例提供的拨档控制器可以为旋转拨档控制器，或其他形式的拨档控制器，对此本申请实施例不做具体限制。
进一步的，本申请实施例提供的所述透射型波长转换层为荧光粉层，即，通过照射荧光粉层产生受激光作为照明装置的出光光源。其中，本申请实施例提供的波长转换装置可以制作为荧光粉片状结构，而后将荧光体划分为多个区域分别对应一透荧光粉层；另外，本申请实施例提供的波长转换装置还可以包括一透明基板，通过将透明基板做为承载基板，以在其上形成多个荧光粉层，对此本申请不做具体限制，需要根据实际需要进行具体选取。

选择Ce:YAG（铈掺杂YAG）透明发光陶瓷层、Ce:YAG和Al2O3共同烧结的复合发光陶瓷层或PIG（Phosphor in Glass）荧光层的好处在于，能够经过加工上述的荧光粉层获得用于镀膜的表面。用于在透射型波长转换层激光入射面镀0度Bluepass膜层和透射型波长转换层的出射面镀增透膜。
另外，本申请实施例提供的激光光源可以为蓝光激光，通过蓝光激光激发上述三种材质的荧光粉层能够产生预设颜色的光。可选的，本申请实施例提供的波长转换装置中，至少两个荧光粉层均为Ce:YAG透明发光陶瓷层或Ce:YAG和Al2O3共同烧结的复合发光陶瓷层时，所述至少两个荧光粉层的厚度不同。其中，当荧光粉层的厚度较薄时，蓝光激光一部分用于激发荧光粉层变换为黄色的受激光，而另一部分蓝光激光直接透过荧光粉层，黄色的受激光和蓝光激光混合成白光；因此，依据上述原理和特征，当荧光粉层为Ce:YAG透明发光陶瓷层或Ce:YAG和Al2O3共同烧结的复合发光陶瓷层时，为了实现照明装置出光色温的不同，可以通过调整荧光粉层的厚度来实现白光不同色温的调整的目的。
此外，当荧光粉层为PIG荧光层时，不仅可以通过调整荧光粉层的厚度实现出光色温调整的目的，还可以通过调整PIG荧光层中Ce:YAG黄色荧光粉的含量，以调整出光色温；即，至少两个荧光粉层均为PIG荧光层时，所述至少两个荧光粉层的厚度不同或所述至少两个荧光粉层中的Ce:YAG黄色荧光粉的含量不同。

具体的，参考图9所示，为本申请实施例提供的一种车辆用前照灯装置的结构示意图，其中，车辆用前照灯装置的波长转换装置可以包括五个透射型波长转换层，且每一透射型波长转换层朝向反射面一侧均设置有一光整形装置。其中，五个光整形装置（60a、60b、60c、60d和60e）可以分别为上述图3、图4a、图4c、图5a和图5c所示的光整形装置。其中，当驾驶员驾驶车辆时，驾驶员可以根据当前行驶的需要通过拨档方式发送切换命令，而后车辆用前照灯装置的控制装置接收该命令控制相应的透射型波长转换层接收激光，通过产生的激发光透过相应光整形装置后照射至反射面出光，以满足驾驶员的需求。
相较于现有技术，本申请实施例提供的技术方案至少具有以下优点：
本申请实施例提供了一种照明装置及车辆用前照灯装置，包括：激光光源，用于出射激光；第一基板和设置于所述第一基板上的反射罩，所述反射罩与第一基板之间具有一出光口，且所述反射罩朝向所述第一基板的一面为反射面；设置于所述第一基板上、且位于所述第一基板与所述反射罩之间的波长转换装置，所述激光光源设置于所述波长转换装置背离所述反光罩一侧，且所述波长转换装置包括多个透射型波长转换层，所述透射型波长转换层用于接收所述激光后，并将所述激光转换为受激光后出射至所述反射面，所述反射面将所述受激光以既定方向反射出所述出光口；以及，与所述波长转换装置连接的控制装置，用于驱动所述波长转换装置以切换相应透射型波长转换层接收所述激光。
由上述内容可知，本申请实施例提供的技术方案，照明装置采用激光照射透射型波长转换层后，将得到的受激光以既定方向出射的方式出光，由于激光光源的亮度高，保证了照明装置的出光亮度高；照明装置的结构简单，且其组成的各个组件的体积有限，保证了照明装置的体积较小；通过反射罩和第一基板的半密闭的固定方式，保证将受激光全部出射，避免了光线的浪费；此外，通过控制装置控制波长转换装置以切换不同透射型波长转换层接收激光，以实现照明装置的不同出光效果，提高了照明装置的适用性和灵活性。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
