Abstract

一种机动车辆照明装置，该装置包括光源（1a，1b）、内配光镜（4）、导光体（3）及其衍化形式光幕（5）、导光体板；光源（1a，1b）具有至少两种不同光色的光源（1a，1b），光源（1a，1b）分别置于导光体（3）的两端入射，内配光镜（4）置于导光体（3）及其衍化形式光幕（5）、导光体板的出射端，光源（1a，1b）分别从两端入射至少两种不同光色的光至导光体（3）及其衍化形式光幕（5）、导光体板，最终通过内配光镜（4）的出射面射出，以共用的发光区域实现不同的功能。

Description

通过共用发光区域实现不同功能的车灯照明装置及其方法 技术领域
本发明涉及车灯领域，具体的，本发明涉及一种通过共用发光区域实现不同功能的车灯照明装置及方法，所述通过共用发光区域实现不同功能的车灯照明装置及其方法可装配各种照明用具(灯泡)，可形成各种不同的照明功能。
背景技术
随着汽车产业的高速发展，对机动车辆照明设备提出更高的要求，包括：
1.在同一发光区域内完成不同功能、不同光照强度及光色的车灯照明，以求达到点灯效果的动态变换效果，同时，实现一个基本上均匀同质的光射出面；
2.由于机动车辆照明设备安装部位的多样性，要求在较小的形状不一的空间内达到上述效果，由此满足新型车灯的设计要求，不影响造型外观，提高车辆照明装置设计的灵活性；
3.用于不同照明功能的照明用具设置不同的单色光源以实现不同的照明功能；
4.上述汽车照明装置除具有下述光学功能：白色的DRL或PL第一功能，黄色的转向灯第二功能之外，还包括其他颜色的车用灯第三种功能。
现有机动车辆照明设备在用于不同照明功能的照明用具设计时需要考虑彼此相邻位置要求，即需要在照明设备中设计相当大的空间来安装这些具有不同功能的照明用具，通常需要所述各个照明用具形成矩阵排列。
但是，所述各个照明用具的矩阵排列需要较大的空间，由此需要照明用具在设计时必须加大安装尺寸，以满足两个以上的照明功能要求。
例如，德国海拉车灯有限公司(HELLA KGAA HUECK&CO)的发明专利“Lighting device for a motor vehicle”(申请号：EP20080163803申请日：2008.09.05)提供了一种具有不同功能的车灯照明装置，所述发明公开的权利要求1的技术方案包括如下特征：
“①对应多项光功能的多组光源；
②与多组光源耦合的导光体，并且该导光体具有至少一个可实现多功能的共同出光面；
③多组光源共用一个光源载体；
④第一光源的功能体现为日行灯和/或位置灯，第二光源的功能体现为转向闪光灯；
⑤白光LED(1a)和琥珀光LED(1b)置于光源载体上。”
然而，该专利技术方案存在的问题是：
所述车灯照明装置无法从不同方向，即任何角度引入多组光源的入射光线，这使得在作车灯光学及结构设计时难以作更灵活的空间布置，例如，因光学原理局限，光源只能由后方入射，前方出射，或导光体采用导光体管形式，由此，使得LED的间距不便调节(在进行普通形式布置，如LED光源从后方入射安排时，由于光学结构的原因，LED间距一般较大，但LED间距大会造成点灯外观不良。在此情况下，需要一种能使得LED间距减小的方案，提高点灯均匀性)，妨碍提高外观均匀性；同时，不便该照明装置各种内部结构布置及有效利用空间；
光学层次感较差，难以满足多种不同的造型方案；
导光体难以与尾灯造型开口紧密贴合，影响造型外观。
又如，“DE 100 43 660 A1”的德国发明专利公开了一种机动车辆的照明装置，所述照明装置使用一个光源载体，用于装配各种车辆照明用具，且共用一个灯体，其中包括两个不同颜色灯光的LED排列成一个灯光总成矩阵，所述灯光总成矩阵设置于一个反光镜或者散射镜后。
又如，公开号为“CN106016127A”、上海小糸车灯有限公司的“一种具有不同功能的车灯照明装置”的发明专利，采用两种不同光色的LED光源，配置在厚壁透明导光体的一侧,最终通过厚壁透明导光体的共同出光面出光，实现两种不同功能；并且LED光源分别单独安装不同的线路板，配置在导光体一侧，以将所述两种不同光色的LED光源的入射光线从不同方向引入厚壁透明导光体。
US8764257的美国专利涉及一种车辆照明装置，该装置包括实现两种光功能的两个光源，以及将两个光源的光传输到出光面的主导光体，这两个光源，一个可以是执行 车辆前照灯功能的白光，另一个可以是执行车辆转向灯功能的黄光。
该专利的权利要求8进一步揭示了采用主导光体和两个辅助导光体的技术方案，使主导光体有两个辅助分叉，这样两个光源的光分别从辅助分叉进入主导光体，在权利要求10中将这种导光体结构进一步限定为Y型结构，即将主导光体和辅助分叉整体设计成Y型，入光口设计在Y的上部，出光口设计为Y的足部。
然而，上述现有的技术方案分别程度不同地存在下述问题：
用于不同照明功能的照明用具需设置不同的单色光源以实现不同的照明功能；
将两套点灯设备拼装在一个车灯装置的空间中，这就需要一个较大的车灯装置空间来设计安装这些照明用具；或
分开排列的点灯设备难以均匀分布在同一发光面，为此因无法满足新型车灯的设计要求；或
因用于不同照明功能的照明用具在设计布置时需彼此相邻，这样在照明设备中须考虑设计相当大的车灯照明装置空间来安装这些照明用具。例如，在各个照明用具的排列需要较大空间的场合，须对照明灯具整体结构作加长设计，以满足不同的照明功能要求；或
因各个照明用具常作为单个灯光源使用，但各种新型车灯照明装置的发光体具有不同结构、形状及发光位置的发光面，例如，所述发光面常形成矩阵式排列，往往导致在以往的照明装置内无法实现一个基本上均匀同质的光射出面；
或
除具有下述光学功能：白色的DRL或PL第一功能，黄色的转向灯第二功能之外，无法实现包括其他颜色的车用灯第三种功能。
发明内容
为克服上述问题，本发明目的在于：提供一种通过共用发光区域实现不同功能的车灯照明装置及其方法，所述一种通过共用发光区域实现不同功能的车灯照明装置及其方法通过安装单色光源就能够实现不同的照明功能，且只需很小的安装空间，可以提高灯具空间利用率。
根据本发明，将不同光色的光源分别布置在一个光传播介质的两端，以共用发光介质实现发光面的均匀效果，节省空间的同时也能满足良好的共用发光面的点灯效果。
根据本发明，可以满足新型车灯的设计要求，不影响造型外观，提高车辆照明装置设计的灵活性。
根据本发明，可以在一个导光体上实现多种功能，包括具有至少两种不同色度要求的光学功能，典型的是，第一功能为白色光学的DRL或者PL，第二功能为黄色光线的转向灯。

具体实施方式
下面结合附图对本发明作进一步详细的说明。
实施例1
如图1所示，本实施例的一种多功能复用的汽车照明装置，光源包括对置于导光体(3)二端的第一光源(1a)和第二光源(1b)，光源载体包括对应第一光源(1a)的第一光源载体(2a)和对应第二光源(1b)的第二光源载体(2b)，设置于导光体(3)外周的作为出光区域的内配光镜(4)。导光体(3)为透明色，光源(1)使用发光二级光(LED)，为单色光源的白色。所述光源、导光体和出光面及内配光镜集成封装在一壳体内。
置于导光体二端的光源分别为不同光色，例如第一光源(1a)的出射光为黄色，第二光源(1b)的出射光为白色，控制仅仅第二光源(1b)的出射光经过导光体(3)后任为白色，实现需要白色光色的第一功能DRL或者PL；控制仅仅第一光源(1a)的出射光经过导光体(3)，通过出光面射出，实现需要黄色光色第二功能的转向灯功能。
另外，进入透明导光体(3)的光源的出射光强度(如波长，亮度等)可控调节，光源出射光的出射状态也可控调节(例如，渐变，闪烁等)。以满足不同需要。
实施例2
如图2所示，在导光体(3)头部或一端分叉出Y形两个端部，第一光源(1a)对应2个第一光源载体(2a)。
第一光源(1a)之一的出射光为黄色，第一光源(1a)之二的出射光为其他颜色，第二光源(1b)的出射光为白色，控制仅仅第二光源(1b)的出射光经过导光体(3)后任为白色，实现需要白色光色的第一功能DRL或者PL；控制仅仅第一光源(1a)之一的出射光经过导光体(3)，通过出光面射出，实现需要黄色光色第二功能的转向灯功能。
使来自导光体一端的2个第一光源(1a)的不同光色同时进入导光体(3)，并在导光体(3)变色或混色后，可形成不同于导光体二端光源的第三种光色，以实现其他颜色的车用灯第三种功能。
所述车用第三种功能包括：雾灯，制动灯，曲线照明及多色的车用氛围灯及装饰灯功能。
其他如同实施例1。
实施例3
如图3所示，在导光体(3)尾部或另一端分叉出Y形两个端部，第二光源(1b)对应2个第二光源载体(2b)。其他如同实施例2。

如图4所示，在导光体(3)二端分别分叉出Y形两个端部，第一光源(1a)对应2个第一光源载体(2a)。第二光源(1b)对应2个第二光源载体(2b)。因进入透明导光体(3)的第一光源(1a)及第二光源(1b)的出射光强度(如波长，亮度等)、出射状态可控调节(例如，渐变，闪烁等)，可由此扩大本发明使用氛围和场合。
其他如同实施例1.

实施例7
在实施例6中，在导光体(3)的出射面或具有衍化形式光幕(5)外周设置导光体板。
导光板具有一定纵深的导光板(内透镜)，面向车灯配光的光轴方向的那一面上作花纹表面处理，使导光体灯具从视觉上看整体发光更加均匀，获得不同的正面点灯效果。
实施例8
如图7所示，辅助导光体(3a)具有前后分隔设置具有二种不同于白光颜色的第一辅助导光体(3a-1)和第二辅助导光体(3a-2)，光源的出射光先后进入第一辅助导光体(3a-1)和第二辅助导光体(3a-2)后，可控地变色或混色为不同于第一辅助导光体(3a-1)及第二辅助导光体(3a-2)的第三种颜色，以实现其他颜色的车用灯第三种功能。例如，实现车内氛围灯功能。
根据本发明，将不同光色的光源分别布置在一个光传播介质的两端，以共用发光介质实现发光面的均匀效果，节省空间的同时也能满足良好的共用发光面的点灯效果。
根据本发明，可以满足新型车灯的设计要求，不影响造型外观，提高车辆照明装置设计的灵活性。
根据本发明，可以在一个导光体上实现多种功能，包括具有至少两种不同色度要求的光学功能，典型的是，第一功能为白色光学的DRL或者PL，第二功能为黄色光线的转向灯。
