Description

光源***及汽车大灯 技术领域
本发明涉及汽车领域，尤其涉及一种光源***及应用所述光源***的汽车大灯。
 背景技术
现代汽车产业的发展对汽车车灯提出了更多更高的需求，如传统的汽车车灯仅用于照明与简单地对行人或前后车指示，然随着汽车产业的发展，要求汽车车灯亦能对本车驾驶员进行指示，如指示驾驶路线等，因此，汽车车灯需能按要求变更显示的图案。
 技术问题
申请号为201480060009.X、名称为“波长转换元件、制造方法和具有波长转换元件的发光半导体部件”的中国专利申请中，揭露了在波长转换元件的陶瓷格栅阵列的每一个格栅中填充转换区段，然其未揭露每一格栅可被单独控制以使每一个格栅根据需显示的图案的需求，产生或不产生受激光，因此，上述专利申请中揭露的波长转换元件与发光半导体部件应用于汽车车灯上时，也无法满足根据需要变更显示图案的需求。
 
 技术解决方案
鉴于上述状况，本发明提供一种能丰富汽车指示功能的光源***及汽车大灯，以解决上述问题。

另一方面，本发明还提供一种应用上述光源***的汽车大灯。
 有益效果
本发明实施例提供的光源***及汽车大灯的优点在于：，由于光源***的发光装置包括多个发光单元，而每一发光单元又能独立被控制在第一位于与第二位置之间切换，因此，通过控制每一发光单元所处位置便能在汽车大灯前方形成所需图案，变更任一发光单元所处位置便能变更形成于汽车大灯前方的图案，扩大了光源***的应用领域、丰富了汽车大灯的指示功能。
附图说明
图1为本发明汽车大灯的光源***的一种结构示意图。
图2为图1所示光源***的发光单元的一种结构示意图。
图3是图1所示光源***的发光单元的另一种结构示意图。
 
 本发明的实施方式
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。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1所示，图1是本发明一种实施方式中的汽车大灯的光源***的结构示意图。所述光源***1包括一激发光源11、一发光装置12以及一控制装置13，所述激发光源11出射激发光，所述激发光激发发光装置12产生受激光，所述受激光被控制装置13控制沿特定的路线出射，从而形成特定的图案投射至汽车大灯前方。在本实施方式中，所述激发光源11可以为激光光源或LED光源。所述发光装置12为一荧光发光装置，包括多个按一定顺序排列的发光单元121，每一发光单元121在激发光的激发下产生受激光，且每一发光单元121能被所述控制装置13控制在一第一位置与一第二位置之间切换。在第一位置时，发光单元121产生的受激光能出射至汽车大灯前方，而在第二位置时，发光单元121产生的受激光不能出射至汽车大灯前方，因此，控制单元13根据所需投射至汽车大灯前方的图案，发送控制信号控制每一发光单元121使其处于第一位置或第二位置，从而将特定的图案透射至汽车大灯前方。
请参阅图2所示，为发光单元121的一种结构示意图与动作示意图，为描述方便，图2中示出了4个一字排开的发光单元121a~121d。每一发光单元121a~121d包括一发光板1211a~1211d与一驱动装置1212a~1212d。每一发光板1211a~1211d在激发光的激发下产生受激光，每一驱动装置1212a~1212d接收控制装置13的控制信号、并根据接收的控制信号驱动对应发光板1211a~1211d在两个位置之间切换，从而使对应的发光板1211a~1211d位于第一位置时，产生的受激光进入第一条路径并沿第一条路径L1最终出射至汽车大灯前方，而在发光板1211a~1211d位于第二位置时，产生的受激光进入第二条路径L2，进入第二条路径L2后受激光无法出射至汽车大灯前方，在本实施方式中，每一驱动单元1212a~1212d设置于对应发光板1211a~1211d背离激发光源11的一侧，每一驱动单元1212a~1212d带动对应的发光板1211a~1211d转动，以将对应发光板1211a~1211d在第一位置与第二位置之间切换。如图2所示，发光板1211a、1211d处于第一位置，因此发光板1211a、1211d产生的受激光进入第一条路径L1并最终出射至汽车大灯前方，而发光板1211b、1211c被对应的驱动单元1212b、1212d驱动至第二位置，因此发光板1211b、1211c产生的受激光进入第二条路径L2，无法出射至汽车大灯前方。
可以理解，在另一种实施方式中，每一发光板1211在第一位置时能接收到激发光源11发出的激发光并产生受激光，受激光经由第一条路径出射至汽车大灯前方，而在第二位置时不能接收到激发光源11发出的激发光，因此也不能产生受激光出射至汽车大灯前方，例如，发光板1211包括一荧光层与一反射层，荧光层设置于发光板1211的第一面，而反射层设置于发光板1211上与第一面相背的第二面，在第一位置时，发光板1211第一面面向激发光源11，荧光层能接收到激发光，而在第二位置时，发光板1211第二面面向激发光源11，反射层隔开荧光层与激发光源11，使荧光层无法接收到激发光源11出射的激发光。
可以理解，图2所示实施方式为每一发光单元121的发光板1211受独立控制，但在其他实施方式中，所述发光单元121可以以组为单位进行控制，即两或多个发光单元121为一组，每组通过一对应的驱动装置根据接收的控制信号驱动其发光单元121共同处于第一位置或第二位置。
在一种实施方式中，所述发光板1211包括荧光层与反射层，其中荧光层为荧光板，反射层为设置于荧光板背离激发光入射一侧的反射膜，所述荧光板可以由荧光物质、玻璃粉通过胶水混合制作成型、也可以由荧光物质、树脂通过胶水混合制作成型。
在另一种实施方式中，所述发光板1211包括荧光层与反射层，其中荧光层为荧光板，反射层为设置于荧光板背离激发光入射一侧的反射基板，所述反射基板的表面为反射面，或者，所述反射基板包含基板和设置用于基板上的反射膜。
在再一种实施方式中，所述发光板1211包括荧光层与反射层，其中反射层为反射基板，荧光层为设置于反射基板上的荧光膜，所述荧光膜通过喷涂或者涂覆的工艺将荧光物质设置于反射基板上。
在一种实施方式中，所述反射基板为一平板，所述荧光层设置于所述平板上。
在另一种实施方式中，所述反射基板包括底壁和周壁，底壁与周壁共同形成一容置空间，所述荧光层设置于所述容置空间内。
在一种实施方式中，所述反射基板的底壁具有反射光的功能，周壁透光。
在另一种实施方式中，所述反射基板的底壁与周壁均具有反射光的功能。
在一种实施方式中，所述反射基板周壁的高度等于荧光层或荧光板的厚度。
在另一种实施方式中，所述反射基板周壁的高度大于荧光层的厚度，如图3所示，在另一种实施方式中，所述发光单元121还可以包括一聚集透镜1213，所述聚集透镜1213通过反射基板1213的周壁固定于发光板1211的荧光层之上，所述聚集透镜1213用于将入射的激发光会聚于发光板1211的荧光层，且用于将所述发光板产生的受激光进行收集及/或准直。
可以理解，聚集透镜1213亦可通过其他方式固定于发光板1211的荧光层之上。
综上所述，本发明的光源***及汽车大灯，由于光源***的发光装置包括多个发光单元，而每一发光单元又能独立被控制在第一位于与第二位置之间切换，因此，通过控制每一发光单元所处位置便能在汽车大灯前方形成所需图案，变更任一发光单元所处位置便能变更形成于汽车大灯前方的图案，扩大了光源***的应用领域，丰富了汽车大灯的指示功能、且成本低亮度高。
以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照以上较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换都不应脱离本发明技术方案的精神和范围。
