Description

光导装置和机动车车顶
本发明涉及一种车顶所用的光导装置，包括多个玻璃板和一个聚合物层压材料的中间层。
本发明还涉及一种带有这种光导装置的机动车车顶。
机动车制造商开发了具有越来越大的装玻璃表面积的型号。特别是为了改进空气动力学轮廓，增加了挡风玻璃和后屏的尺寸。此外，在遮阳蓬顶的制造中，装玻璃变得占有优势。随着这种趋势，机动车辆装备了越来越大滑动玻璃遮阳蓬顶或全景玻璃顶，而不管关于空调工程方面的缺点，例如由于绝热而造成的车舱的过热。仍然提供这种顶的原因是宽敞友好的空间环境为乘客带来明亮的、光线充足的客舱。常规的关闭顶衬层只通过穿过侧窗入射于客舱中的杂散光间接地照亮客舱。与明亮的环境形成的强烈对比引起常规型顶衬层显得比较暗并且可能对司机具有压抑效果。
光导装置可被用于带有透明车顶例如所谓的遮阳蓬顶的车辆中，或者用于带有不透明车顶例如带有普通顶衬层的车辆中，在这种情况下光导装置邻近车顶设置。
光导装置见于US-A 2002/0 167 820。这种已知光导装置包括发光单元和光波导管，发光单元可电接通和关闭，而光波导管用于引导光并联接至发光单元上以便接入光。在这种已知光导装置中，光波导管设置于车顶内部衬层的区域中并且设计为扁平的光波导管，光在光波导管的一个或多个侧面处接入。此外制备扁平的光波导管以便使得出自光波导管的光以大表面积并以均匀方式接入车辆的客舱中。这种已知光导装置改进了机动车辆的客舱的照明条件。这种已知光导装置的缺点是通过玻璃装置发出的光具有浅绿色。
为此目的，本发明提供了一种消除了所述缺点的光导装置。根据本发明，开头段落中所述的这种光导装置为此目的包括：
-多个玻璃板，
-插入玻璃板之间的聚合物层压材料构成的中间层，
-用于将光接入光导装置中的光耦合装置，
-接入中间层的光基本上被引导穿过中间层。
当光穿过玻璃板超过相当可观的距离(通常超过几厘米)并且随后从玻璃板接出时，发出的光具有浅绿色。这种浅绿色是由于玻璃中吸收和/或选择散射引起。这种浅绿色可以借助于使用非常特殊类型的玻璃来防止。这种特殊类型的玻璃比较昂贵，这使得它们较不适用于机动车辆。根据本发明的光导装置已经适于保证接入光导装置中的光基本上被引导穿过中间层，从而光避免还穿过玻璃板。因此，就大大地避免了这种光导装置发出浅绿色光的情况。此外，玻璃板上的雨滴或者存在于玻璃板上的划痕或者粉尘的作用不会影响从光导装置接出的光的均匀性，因为光不会经过玻璃板。
在已知的光导装置中，构成中间层的材料选择成使得中间层的折射率与玻璃板的折射率基本上相同。用于中间层的众所周知的材料为聚乙烯醇缩丁醛(PVB)和乙烯-乙酸乙烯酯(EVA)。接入已知光导装置的光并不在两个玻璃/中间层界面的任何一个处反射，因为中间层材料的折射率如此接近玻璃的折射率。因此，光导装置中的光不但穿过玻璃板，而且穿过中间层。当这种光最后从光导装置中接出时，其将会由于玻璃板中的吸收效应而成为浅绿色。
根据本发明的措施使光导装置中的光通路基本上出现于中间层中，同时减少了光将会穿过玻璃板的机会。在根据本发明的光导装置中，全内反射的原理用于中间层与玻璃板之间的界面处。按照这种方式，在根据本发明的光导装置中的中间层用作主要光波导管。
存在用于在中间层与玻璃板之间的界面处实现全内反射的若干实施例。为此目的，根据本发明的光导装置的优选实施例特征在于中间层的折射率高于玻璃板的折射率。由于玻璃板与中间层之间的折射率的区别，所以穿过光导装置的光基本上被引导穿过中间层。构成中间层的材料的折射率必须选择成使得没有穿过中间层的光被接入邻近中间层的玻璃板中。为此目的，根据本发明的光导装置的优选实施例特征在于中间层的折射率高于1.57。中间层与玻璃板之间的折射率区别越大，将光接入光导装置中的数值孔径就越大。这种中间层所用的适当材料为聚碳酸酯(折射率大约为1.59)。
另一种用于在中间层与玻璃板之间的界面处实现全内反射的方法是在中间层与玻璃板之间的界面处插入折射层。为此目的，根据本发明的光导装置的优选实施例特征在于在每个玻璃板与中间层之间邻近中间层提供了由折射率低于中间层的折射率的材料构成的折射层。折射层使得光优选地在中间层中行进，并且避免了光从中间层接出并进入玻璃板。构成折射层的材料的折射率必须选择成使得没有穿过中间层的光被接入邻近折射层的玻璃板中。为此目的，根据本发明的光导装置的优选实施例特征在于折射层的折射率低于1.50。这种折射层所用的适当材料为聚甲基丙烯酸甲酯、氟化镁和特氟隆。
根据本发明的光导装置的有利实施例特征在于光耦合装置适于将大部分光接入中间层。这种措施有利于光穿过中间层行进并且基本上避免了接入光导装置中的光穿过玻璃板。优选地，光导装置带有凹槽，凹槽适于容放光耦合装置。
本发明的这些和其它方面可以清楚地从下面所述的实施例看出，并参考它们来阐明。
在附图中：
图1为根据本发明的车顶所用的的光导装置的实施例的剖视图，以及
图2为根据本发明的车顶所用的的光导装置的替代实施例的剖视图。
附图纯粹为示意性而非按比例绘制。特别是为清楚起见，某些尺寸放大很多。在图中，只要有可能，同样的参考数字指的是同样的零件。
图1为根据本发明的光导装置的实施例的剖视图。这种光导装置改进了机动车辆的客舱中的照明条件。光导装置优选地设置于车顶的内部衬层的区域中并且优选地设计为扁平的光波导管。光导装置制备成使得出自光导装置的光以大表面积并以均匀方式接入车辆的客舱中。与常规型光源例如白炽灯不同，根据本发明的光导装置并不用作离散的发光元件而是对车辆乘客的头顶区域中的顶衬层产生大表面且不耀眼的光亮。这种光导装置产生好像放大了客舱的感觉，创造了舒适的空间环境。这样的优点是客舱的均匀照亮对车辆乘客具有正面的心理-生理作用。这种对车辆乘客的正面作用特别是在黑暗中实现，例如当驶入隧道或者在夜里驾驶时。根据本发明的光导装置实现了在黑暗中将客舱不耀眼地照亮，因此车辆乘客的适应情况得到改进。此外，由明亮的顶创造的舒适的空间环境促进了在黑暗中专心且无压力地驾驶。光导装置的另一个优点是其可用作整个车辆的部件，特别是用作车辆的客舱中的设计元件。
在图1的实施例中，光导装置包括两个玻璃板1、2。玻璃板1、2由普通窗玻璃(折射率1.54)制成。在替代实施例中，板由例如聚甲基丙烯酸甲酯(PMMA)、聚碳酸酯(PC)或者某些其它适当的材料制成。在替代实施例中，玻璃板之一(优选地位于面向车辆外部的一侧)由例如用于减少来自太阳光的热输入的吸光材料制成。板对于可见光而言是半透明的。此外，板之一可为彩色和/或可包括用于减少来自车辆外部的热输入和/或减少从车辆到外部的热损失的装置。在玻璃板1、2之间插入由聚合物层压材料构成的中间层3。提供了光耦合装置5以便将光接入光导装置。在图1的实施例中，光耦合装置5包括从远程光源发光的光导纤维。光导纤维联接至可电接通和关闭的发光单元(图1中未示出)上。适当的发光单元由一个或多个荧光灯、发光索或发光二极管形成。这种光源具有小的总深度，容许节省空间地安装于车辆中。例如，发光单元可以放置于车辆的侧向纵梁中。优选地，提供电控制回路(图1中未示出)，包括用于使射入车辆客舱中的光强度与环境亮度相适应的亮度传感器。
根据本发明，接入中间层3中的光基本上通过全内反射穿过中间层3传播。在图1中所示的本发明的实施例中，因为中间层3的折射率高于玻璃板1、2的折射率，所以这点得到实现。按照这种方式，接入光导装置的光优选地穿过中间层，并且基本上避免了光穿过玻璃板传播。构成中间层的材料的折射率必须选择成使得没有穿过中间层的光被接入邻近中间层的玻璃板中。为此目的，根据本发明的光导装置的优选实施例特征在于中间层3的折射率高于玻璃板1、2的折射率。优选地，中间层3的折射率高于1.57。适当的中间层材料为聚碳酸酯(PC；折射率大约为1.59)。
优选地，光耦合装置5适于将大部分光接入中间层3。在图1的实例中，光导装置带有凹槽10。凹槽10适于容放光耦合装置。这种凹槽10使得大部分光被接入中间层3。在替代实施例中，光源直接提供于凹槽10中。
在光导装置中传送的光的范围、色彩和强度由光波导管的纵横比，即长度与厚度或直径的比值确定。优选地，玻璃板1、2的厚度大约为2.1mm而中间层3的厚度大约为1.52mm。
为了从光导装置接出光，将所谓的散射中心20引入光导装置以便接出在光导装置中引导的光。在替代实施例中，散射中心只提供于中间层的一侧，从而将光的接出只限制于一个方向。由于光优选地穿过中间层传播，根据本发明，散射中心20优选地应用于中间层3的边界面处。这种散射中心20优选地为折射率很高的颜料例如白漆、氧化钛或粒度大于(可见)光的波长的夹气。散射中心20处的不连续性引起中间层3中引导的光在这些散射中心处偏转。散射中心20还可有利地设计为纤维或彩色颗粒。此外，散射中心可为粒度低于可见光的波长的颗粒。在这种情况下，光的偏转由具有各向同性散射角度分布的瑞利散射确定。部分散射光直接进入车辆的客舱。沿车顶方向散射的这部分光优选地通过设置于车顶和光导装置之间的反射盖反射回光导装置中。替代地，车顶的内部衬层可显示出反射性能。
图2为根据本发明的光导装置的替代实施例的剖视图，其包括两个半透明玻璃板1、2。由聚合物层压材料构成的中间层3插入玻璃板1、2之间。提供了光耦合装置5以便将光接入光导装置。在图2的实施例中，由折射率低于中间层3的折射率的材料构成的两个折射层8、9提供于相应的玻璃板1、2和中间层3之间，邻近中间层3。折射层可以用作位于玻璃板1、2中每一个上的涂层。此外，折射层还可为粘合剂层，从而简化制造过程。优选地，构成中间层3的材料选择成使得中间层的折射率与玻璃板1、2的折射率基本上相同。用于中间层的众所周知的材料为聚乙烯醇缩丁醛(PVB)和乙烯-乙酸乙烯酯(EVA)，这两种材料都具有约为1.49的折射率，即与玻璃板的折射率近似相同。为了从光导装置接出光，将所谓的散射中心20被引入光导装置以便接出在光导装置中引导的光。优选地，散射中心20提供于中间层3和折射层8之间。在图2的实例中，散射中心20只提供于中间层的一侧，从而将光的接出只限制于一个方向。
折射层8、9使得光优选地在中间层中行进，并且避免了光从中间层接出并进入玻璃板。构成折射层8、9的材料的折射率选择成使得没有穿过中间层的光被接入玻璃板中。如果中间层由PVB制成，则折射层的折射率优选地低于1.42，产生0.47的数值孔径(N.A.)。这种折射层所用的适当材料为聚甲基丙烯酸甲酯(PMMA；折射率约为1.47)、氟化镁(MgF2；折射率约为1.38)和特氟隆(折射率≤1.35)。当较低折射率的折射层提供于中间层和玻璃板之间时，中间层的折射率和玻璃板的折射率优选地近似相同。
在图2的实例中，光导装置带有凹槽10。凹槽10适于容放光耦合装置。这种凹槽10使得大部分光被接入中间层3中。当将光接入由PVB制成的中间层3利用通常具有约为0.47的数值孔径(N.A.)的塑料光纤执行时，折射层8、9的折射率优选地应当为：
N.A.＝[(ninterlayer)2-(nrefractive layer)2]1/2，
产生折射层的折射率nlayer≤1.42。如果光学纤维的N.A.更大，则理想的是具有较低折射率的折射层。
应当指出上述实施例对本发明进行示例说明而非限制，本发明所属领域的普通技术人员将能在不背离所附权利要求的范围的情况下设计许多替代实施例。在权利要求中，套入括号内放置的任何参考符号不应被认为是限制权利要求。使用动词“包括”及其动词变化并不排除存在除了权利要求中所述的元件或步骤以外的元件或步骤。元件前面的的冠词“一”、“一个”或“一种”并不排除存在多个此类元件。本发明可以利用包括若干不同元件的硬件和利用适当地编程的计算机实现。在列举了若干装置的设备权利要求中，这些装置中的若干可由硬件的同一项具体实现。某些措施在互不相同的从属权利要求中叙述的纯粹事实并不表示不能使用这些措施的组合来获益。
