Abstract

指针帽照明，本发明涉及用于车辆仪表板的发光指针帽，其通过将白光引导穿过不同的滤色器而从白色光源输出不同的颜色。白光透射穿过光导基板，并通过在基板的与滤色器相对的一侧上形成的三角形底切而反射到滤色器。

Description

指针帽照明
背景技术
由于多种原因，许多车辆仪表盘使用多颜色显示器。然而，在仪表盘上提供多种颜色需要相应的有色光源。提供多种不同颜色但使用单个白色光源的仪表板显示器将是对现有技术的改进。
附图说明
图1是仪表板显示装置（例如转速表）的透视图，该仪表板显示装置提供多颜色光输出，其颜色是从单个白色光源获得的；
图2是图1中所示的显示装置的“顶”视图；
图3是图1和图2中所示的装置的穿过剖面线A-A的剖视图；
图4是图1至图3中所示的显示装置的一部分的隔离视图；和
图5是图1至图3中所示的装置的替代实施例的隔离视图。
具体实施方式
图1是用于仪表板的多颜色显示器100的透视图。在图1中，该装置是转速表。显示装置100包括电路板1，电路板1支撑单个白色发光二极管（LED），在其上方是由“柱部分”5和“平坦部分”7组成的一体的透光丙烯酸“基板”。
显示器具有从平坦部分7的顶表面11输出的多颜色光，平坦部分7由柱部分5支撑并附接到柱部分5。顶表面11具有斜切的外围边缘13，其外角由附图标记9标识。
图2是图1所示装置的顶视图。平坦部分7具有顶表面11和相对的底表面12。柱部分5和平坦部分7是由透光丙烯酸或聚碳酸酯制成的一体结构。如本文中所使用的，柱部分5和平坦部分7被认为是透光的丙烯酸或聚碳酸酯基板，其光学地耦合到附接到电路板1的白色光源2。
图3是图1和图2中所示的装置的穿过剖面线A-A截取的剖视图。柱部分5基本上是圆柱，即在本文中被认为是大致柱状的。它具有在白色光源2正上方的第一端6。相对的第二端8具有斜切的外角9，并且是与平坦部分7相连或一体的结构。由于柱状的柱部分5和平坦部分7是一体的结构并且由透光丙烯酸制成，从光源2发出的光被耦合到柱部分5的大致平坦的第一端，向上行进穿过柱部分5，并由斜切的外角向侧面地或侧向地反射进入平坦部分7。
仍然参考图3，平坦部分7设有底切15，底切基本上是形成在平坦部分7的下表面或底表面12中的三角形切口。底切15具有斜边17，斜边17延伸到平坦部分7中，并且相对于底表面12和水平线以预定角度21朝向顶表面或第二表面11倾斜。底切的斜边侧反射使光向上穿过平坦部分并朝向顶表面11行进。
现在参考图4，更详细地示出了平坦部分7的底切和相邻区域的隔离视图。平坦部分7的顶表面11涂覆有高折射率涂层23。黑色基体层27覆盖高折射率涂层23。窗口25被切开或蚀刻穿过黑色基体层27，但是并不延伸穿过高折射率涂层23。
窗口25位于底切15的斜边17上方的黑色基体层27中。因此，来自白色光源2的光向上行进穿过柱部分5、由斜切的外角9反射、行进穿过平坦部分7、由斜边17反射并穿过窗口25发出。
现在参考图5，示出了用于车载仪表板的多颜色发光指针帽。图5中所示的实施例与图4中所示的实施例的不同在于：在平坦部分7的顶表面和底表面两者上增加两个三角形底切15和高折射率。图5中所示的实施例与图4中所示的实施例的不同还在于：增加形成在黑色基体层27中的两个窗口25和26，窗口25在第一滤色器层29上方，第二窗口26在第二滤色器层31上方。两个滤色器层均在高折射率涂层23上方，高折射率涂层23在平坦部分7的顶表面11上方。
另外，底切的斜边表面也涂覆有相同的高折射率涂层23。
在运行中，从白色光源2发出的白光沿柱部分5向上行进、由斜切的边缘侧向地反射，该斜切的边缘也优选地涂覆有高折射率涂层23。白光向侧面地或侧向地反射进入平坦部分，在该平坦部分，其碰到倾斜的斜边表面，两个斜边表面都进行了涂覆。来自两个斜边侧的光被向上反射，并且被投射穿过不同颜色的滤光器，从而提供来自图1中所示的仪表100的不同颜色的光。
如本文所用，术语“高折射率涂层”是具有大于约1.3但高达约1.8或更高的折射率的材料。在优选的实施例中，白色光源是白色发光二极管。在另一个实施例中，高折射率涂层被白色涂料代替。黑色基体层27可以是黑色涂料。窗口可以通过激光蚀刻或研磨（abraiding）形成。
前述描述仅出于说明的目的。本发明的真实范围在所附的权利要求书中提出。
