Description
技术领域
本发明涉及车辆的照明装置,更具体地涉及发射各种颜色光的装置。
背景技术
通常,车辆设置有照明装置,使驾驶者可以在夜间驾驶时清楚识别出驾驶方向上的物体,并向行人和/或其它车辆的驾驶员通知驾驶员车辆的驾驶状况。大灯,也被称为前照灯,是照亮车辆前方道路的车灯。
这种车灯可以分为前照灯、雾灯、转向信号灯、刹车灯、后照灯(back up lamp)等,其对路面的发光方向分别设置为不同。
由于投射光的颜色取决于光源和透镜的颜色,这些车灯的光自由度很低。此外,为了发射各种颜色的光,还额外设置了用于表达颜色的光源、反射面和透镜,造成布局复杂并增加了制造成本。
本发明的背景技术部分所公开的信息仅用于加强对本发明的一般背景的理解,而不视为确认或任何形式的暗示该信息组成本领域技术人员的现有技术。
发明内容
本发明的各个方面致力于提供一种车辆的照明装置,其中,该装置发射各种颜色的光而不需要增加复杂的设计,并且能够通过颜色的组合根据各种驾驶条件来确定光的颜色。
本发明的各个方面提供一种车辆的照明装置,该装置包括:光源,其发射预先确定的颜色的光;反射器,其反射从光源发射的光以向外投射光,所述反射器具有的颜色不同于从光源发射的光的颜色以在光被反射时改变光的颜色;以及光透射率可变部分,其设置在所述光源和所述反射器之间,使得从光源发射的光在入射到反射器之前入射到所述光透射率可变部分上,所述光透射率可变部分配置为改变光透射率;其中,当透射率可变部分设定为具有低光透射率时,从光源发射的光被光透射率可变部分反射,从而以预先确定的颜色投射;而当光透射率可变部分设定为具有高透射率时,从光源发射的光透过光透射率可变部分并且被反射器反射以改变颜色,从而以改变的颜色投射。
反射器可以是具有曲率的抛物线形,光源可以设置在反射器的抛物线焦点处,并且光透射率可变部分整合连接至反射器并且具有与反射器相同的曲率。
光透射率可变部分可以是根据是否向其施加电力而改变光透射率的可变薄膜。
所述装置可以进一步包括:外部透镜,其设置在沿从光源发射的被反射器反射并投射的光的路径上,所述外部透镜具有的颜色不同于从光源发射的光的第一预先确定的颜色和反射器的颜色。
反射器可以具有多个曲面,所述多个曲面配置为使得曲面中的全部或一些具有不同的颜色。
可以设置多个光透射率可变部分,以分别对应于反射器的多个曲面,并且多个光透射率可变部分可以配置为独立地改变光透射率。
可以在光源和反射器之间设置至少两个或更多个光透射率可变部分,并且多个光透射率可变部分之间可以插入多个不同颜色的彩色透镜。
多个光透射率可变部分和彩色透镜可以按顺序相互堆叠在反射器上。
多个光透射率可变部分可以配置为独立改变光透射率,并且光透射率的改变执行为使得光透射率在从光源发射的光传输到反射器的方向上按顺序地改变。
根据具有上述配置的车辆的照明装置,可以通过光的各种颜色的组合实现向外发射各种颜色的光,从而根据驾驶条件执行照明功能并改善照明设计。此外,改变光透射率的薄膜型光透射可变部分配置为连接反射器,从而可以实现各种颜色的光而不需要增加布局的复杂性,并且根据各种驾驶条件确定光的颜色,从而提高车灯的可见性和安全性。
本发明的方法和装置具有其它特点和优势,其将在包含在此的附图和以下详细的描述中变得明显或进行更详细的说明,附图和说明一起解释了本发明的某些原则。
附图说明
图1为显示了根据本发明的示例性实施方案的车辆的照明装置的示意图;
图2为显示了图1所示的第一种车辆的照明装置的示意图;
图3为显示了图1所示的车辆的照明装置的各种示例性实施方案的示意图;以及
图4为显示了图1所示的车辆的照明装置的各种示例性实施方案的示意图。
应当理解,附图不一定是按照比例绘制,而是呈现对本发明的基本原理进行说明的各种特点的简化表示。本发明所公开的具体设计特征,例如包括具体尺寸、方向、位置和形状,将部分地由具体的应用和使用的环境来确定。
在所附多个附图中,同样的或等同的部件以相同的附图标记标引。
具体实施方式
下面将详细参考本发明的各个实施方案,这些实施方案的示例呈现在附图中并描述如下。尽管本发明将结合具体实施方案进行描述,但是可以理解本说明书并不旨在将本发明限制在这些具体实施方案中。另一方面,本发明旨在不仅覆盖具体实施方案,还包括各种替代的实施方案、修改的实施方案、等价的或其它的实施方案,所述实施方案包含在有所附权利要求所定义的本发明的精神和范围中。
下文中,将参考附图对根据本发明示例性实施方案的车辆的照明装置进行详细地描述。在附图中,相同的附图标记将用于表示相同或类似的元件。
图1为显示了根据本发明的示例性实施方案的车辆的照明装置的示意图,图2为显示了图1所示的第一种车辆的照明装置的示意图,图3为显示了图1所示的车辆的照明装置的各种示例性实施方案的示意图,以及图4为显示了图1所示的车辆的照明装置的各种示例性实施方案的示意图。
如图1和图2所示,车辆的照明装置可以包括:光源10、反射器20和光透射率可变部分30,所述光源10发射预先确定的颜色的光;所述反射器20反射从光源10发射的光以向外透射光,反射器具有与从光源10发射的光的颜色不同的颜色以在光被反射时改变光的颜色;所述光透射率可变部分30位于光源10和反射器20之间使得从光源10发射的光在入射到反射器20之前入射到光透射率可变部分30上,光透射率可变部分配置为改变光的透射率。
如上所述,本发明包括光源10、反射器20和光透射率可变部分30,其中光源10是LED,并且反射器20反射从光源10发射的光以改变向外投射的光的传输路径。本文中,从光源10发射的光的颜色和反射器20的颜色彼此不同,由此从光源10发射的光的颜色由于被反射器20反射时的互补色而改变,使得向外发射的光的颜色改变。
进一步地,反射器20呈弯曲的抛物线形,并且光源10位于反射器20的抛物线的焦点,使得从光源10发射的光被反射器20反射,从而沿符合反射器20的抛物线形的路径传输投射。抛物线形反射器20具有与之整合联接的光透射率可变部分30,并且光透射率可变部分30设定为具有低光透射率,导致从光源10发射的光被反射为沿与反射器20相同的路径传输。
本文中,由于光透射率可变部分30配置为改变光的透射率,因此可以改变向外发射的光的颜色。换言之,当光透射率可变部分30设定为具有低光透射率时,从光源10发射的光被光透射率可变部分30反射,从而以预先确定的颜色向外投射。相反地,当光透射率可变部分30设定为具有高光透射率时,从光源10发射的光透过光透射率可变部分30传播,并且被反射器20反射以改变颜色,从而以改变的颜色向外投射。
如上所述,取决于光透射率可变部分30的光透射率,从光源10发射的光向外发射而不改变颜色,或者在因反射器20而改变颜色后向外发射。这使得向外发射的光根据光透射率可变部分30的光透射率选择性地改变颜色。进一步地,由于光透射率可变部分30整合连接至反射器20,所以本发明可以简化用于改变光的颜色的配置,从而可以简化布局。
将详细地描述上述的本发明。光透射率可变部分30可以是光透射率可变薄膜,其光透射率根据是否向其施加电力而改变。
光透射率可变部分30可以是各种光透射率可变薄膜,例如悬浮粒子设备薄膜、聚合物分散液晶薄膜、胆甾醇液晶膜、电致变色薄膜、电子偏光膜等等。光透射率可变部分30的光透射率可以根据是否施加电力而改变,是否施加电力由车灯控制器E的控制来确定。
换言之,当不施加电力时,光透射率可变部分30由于光透射率减小而反射入射光,由此从光源10发射的光被透射率可变部分30反射,从而以预先确定的颜色向外发射。相反地,当向光透射率可变部分30施加电力时,光透射率可变部分30转换为透明状态以增加光透射率,从而透射入射的光。此后,经过光透射率可变部分30透射的光入射到反射器20上以通过反射器20改变颜色,从而以改变的颜色向外发射。
光透射率可变部分的光透射率根据是否施加电力可以设定为与上述实施例相反。相应地,根据向光透射率可变部分30施加的电力的量,一些光可以被反射,一些光可以被透射,将向外发射的光的改变为各种颜色。
同时,如图1和图2所述,本发明可以进一步包括外部透镜40,其沿从光源10发射的被反射器20反射并投射的光的路径设置,外部透镜具有与从光源10发射的光的颜色和反射器20的颜色不同的颜色。
外部透镜40设置在光最终向外发射的位置上,并且与灯壳H集成。由于外部透镜40具有的颜色不同于从光源10发射的光的颜色和反射器20的颜色,这使得光最终以改变的颜色向外发射。
例如,假设从光源10发射的光的颜色是蓝色,反射器20的颜色是绿色,而外部透镜40的颜色是红色。当光透射率可变部分30设定为低光透射率时,从光源10发射的光被光透射率可变部分30反射,导致洋红色的光通过外部透镜40向外发射,洋红色源于从光源10发射的光的蓝色和外部透镜40的红色的组合。
另一方面,当光透射率可变部分30设定为高光透射率时,从光源10发射的光透过可变部分30并被反射器20反射,导致白色的光通过外部透镜40向外发射,白色源于从光源10发射的光的蓝色、反射器20的绿色和外部透镜40的红色的组合。
如上所述,通过从光源10发射的光、反射器20的颜色以及外部透镜40的颜色组合,由于互补色的存在,可以选择性地向外发射各种颜色的光。
作为车辆的照明装置的各种示例性实施方案,并且如图3所示,反射器20可以具有多个曲面。多个曲面可以配置为使得曲面中的全部或一些具有不同的颜色。
相应地,由于反射器20具有多曲面,并且多曲面具有不同的颜色,这允许从光源10发射的光入射到多曲面上,使得最终向外部发射的光有部分不同的颜色。
作为实施例,如图3所示,假设反射器20的曲面包括第一曲面21、第二曲面22和第三曲面23,第一曲面21和第三曲面23是青色,第二曲面是绿色。本文中,当从光源10发射的光的颜色是红色时,入射到第一曲面21和第三曲面23的光的颜色可以变为白色,而入射到第二曲面22的光的颜色可以变为黄色。
此外,当光透射率可变部分30设定为低光透射率时,从光源10发射的光被光透射率可变部分30反射,从而以红色向外发射。
同时,可以设置多个光透射率可变部分30分别对应于反射器20的多个曲面,并且多个光透射率可变部分30配置为独立改变光透射率。相应地,所述光透射率可变部分30分别对应于反射器20的多个曲面,对反射器20的每个曲面部分地改变光透射率。
参考根据图3的实施例,在对应于形成反射器20的第一曲面21、第二曲面22及第三曲面23的光透射率可变部分30中,当对应于第一曲面21和第三曲面23的光透射率可变部分30设定为低光透射率,而对应于第二曲面22的光透射率可变部分30设定为高光透射率时,被对应于第一曲面21和第三曲面23的光透射率可变部分30反射的光可以以红色向外发射,而透过对应于第二曲面22的光透射率可变部分30并被第二曲面22反射的光可以以黄色向外发射。此外,当对应于第二曲面22的光透射率可变部分30的透射率设定为反复地从高光透射率转换为低光透射率时,被第二曲面22反射并向外发射的光的颜色反复地从黄色变为红色。这可以实现转向信号灯。
如上所述,通过反射器20具有多曲面且光透射率可变部分30分别对应于所述曲面的配置,可以根据反射器20的多曲面的颜色部分地改变向外发射的光的颜色。此外,光透射率可变部分30选择性地改变光透射率,使得对应于多曲面中的预先确定的曲面的光透射率可变部分30的光透射率改变,促进了对应于车辆的驾驶条件的可感知的颜色的光向外发射。
另一方面,作为车辆的照明装置的各种示例性实施方案,并且如图4所示,可以在光源10和反射器20之间设置至少两个或更多的光透射率可变部分30。多个光透射率可变部分30可以具有插置在其间的不同颜色的多个彩色透镜50。
相应地,不同颜色的彩色透镜50位于多个光透射率可变部分30之间,由此可以选择性地改变光透射率可变部分30的光透射率,从而改变通过颜色透镜50透射的光的颜色。
为此,多个光透射率可变部分30和彩色透镜50可以在反射器20上按顺序相互堆叠。换言之,如图4所示,不同颜色的彩色透镜50可以位于多个光透射率可变部分30之间。彩色透镜50和光透射率可变部分30可以在从光源10发射的光传输到反射器20的方向上按光透射率可变部分30和彩色透镜50的顺序相互堆叠。相应地,彩色透镜50位于光透射率可变部分30之间并且固定在反射器20上。
进一步地,多个光透射率可变部分30可以配置为独立地改变光透射率。光透射率的改变执行为使得光透射率在从光源10发射的光传输到反射器20的方向上按顺序改变,使得光的颜色按顺序由彩色透镜50改变。
作为实施例,并如图4所示,从光源10发射的光的颜色可以是A颜色,彩色透镜50可以由B颜色的透镜51和C颜色的透镜52构成,并且反射器20的颜色可以是D颜色,而光透射率可变部分30可以由第一可变部分31、第二可变部分32和第三可变部分33构成。本文中,光透射率可变部分30和彩色透镜50可以按以下顺序相互堆叠:第一可变部分31、B颜色的透镜51、第二可变部分32、C颜色的透镜52、第三可变部分33和反射器20。
因此,当第一可变部分31设定为高光透射率时,从光源10发射的光被第一可变部分31反射,从而以A颜色向外发射。
另一方面,当第一可变部分31设定为具有高光透射率并且第二可变部分32设定为具有低光透射率时,从光源10发射的光在透过第一可变部分31和B颜色的透镜51然后被第二可变部分32反射的同时改变颜色,由此光以A+B颜色向外发射。
另一方面,当第一可变部分31和第二可变部分32设定为具有高光透射率而第三可变部分33设定为具有低光透射率时,从光源10发射的光在透过第一可变部分31、B颜色的透镜51、第二可变部分32和C颜色的透镜52然后被第三可变部分33反射的同时改变颜色,由此光以A+B+C颜色向外发射。
另一方面,当第一可变部分31、第二可变部分32和第三可变部分33设定为具有高光透射率时,从光源10发射的光在透过第一可变部分31、B颜色的透镜51、第二可变部分32、C颜色的透镜52和第三可变部分33然后被反射器20反射的同时改变颜色,由此光以A+B+C+D颜色向外发射。
如上所述,通过以下配置,可以通过光的颜色组合向外发射各种颜色的光,在该配置中:多个光透射率可变部分30和彩色透镜50在反射器20上按顺序相互堆叠,并且多个光透射率可变部分30根据最终向外发射的光的颜色选择性地改变光透射率。
根据具有上述配置的车辆的照明装置,可以通过光的各种颜色的组合实现向外发射各种颜色的光,从而根据驾驶条件执行照明功能并改善照明设计。此外,改变光透射率的薄膜型光透射率可变部分30配置为与反射器20接合,从而可以实现各种颜色的光而不需要复杂的布局,并且根据各种驾驶条件确定光的颜色,从而提高车灯的可见性和安全性。
