Description

具有多个照明功能的后信号设备
技术领域
本发明涉及一种用于机动车辆且具有多个照明功能的后信号设备。
本发明涉及机动车辆的用于照明(更具体地用于后照明)的电气设备的领域。所述后照明包括多个对机动车辆的驾驶员有用的灯(例如倒车灯)和多个对车辆外部的人有用的灯:位灯、刹车灯、倒车灯、牌照板照明灯和后雾灯。目前用于这些照明的技术包括用白炽灯泡的照明和用LED(英语术语“Light-Emitting Diode(发光二极管)”的首字母缩合词)的照明。所述LED具有许多优点,尤其是具有低功耗和长寿命。这些LED通常安装在PCB(英语术语“Printed Circuit Board(印刷电路板)”的首字母缩合词)上。
对于用于机动车辆的牌照板(plaque de police)的后灯,通常在所述牌照板上方或下方安置两个后灯,以照亮所述牌照板而不隐藏所述牌照板。
用于机动车辆的后牌照板的传统信号设备参考图1的示意性剖视图来示出。在图1上,LED 3从上方照亮安置成抵靠车辆“V”的牌照板7。该LED 3向下定向并且安置在印刷电路PCB板2的下侧上,所述印刷电路板安置在主透镜5上方并且处于水平位置。这3个设备(LED 3、PCB 2和主透镜5)容置在壳体1中,所述壳体安置在牌照板7上方。菲涅尔透镜(lentille de Fresnel)6使LED 3的输出光束4朝向牌照板7定向。壳体1在所述牌照板7上方的位置不妨碍在由所述输出光束4照亮的范围9中看到所述牌照板7。第二壳体1也经常安装在牌照板7上方。一个或多个壳体1还可安装在牌照板7下方。
背景技术
已给LED在车辆的照明灯中的使用提供了多个改善。例如专利文件WO2011026088描述了一种将LED安装在PCB板的两侧上的简单安装,所述PCB板水平地安置在后照明组件中。这些LED用于借助于LED(从上到下地)直接照亮牌照板,以及借助于多个LED(从该PCB板上方起地)直接照亮多个灯(例如位灯或停车灯)。
另外,文件WO2005002918示出了一种配备有波导的后灯,所述波导安置在该灯的一侧上并且能够获取后灯的光的一部分,以向牌照板的照明提供所获取的光。另一文件EP1750054示出了一种具有三个LED的照明灯,所述三个LED在“V”形的光学模块后方对齐,所述光学模块安置在这些LED前方且处在中央,并且同时地用作对于中央LED的光导以及多个类型的灯的照明工具。
这些改善能够节省LED的数量或者改善经发射的光的美观度,但全都不可设置使得能够基于同一照明载体产生第二光功能以便简化车辆的后灯组件的照明。
发明内容
本发明利用车身上的后牌照板以及与所述后牌照板相面对的照明装置的下部中央位置,以便允许附加地安装至少一个后灯(例如后雾灯和/或倒车灯或其它),以因此产生第二光功能和任选地其它光功能。
更确切地,本发明的目的在于提供一种用于机动车辆且具有多个照明功能的后信号设备,所述后信号设备包括印刷电路板,所述印刷电路板装配有至少一个光源,所述至少一个光源与用于平坦的牌照板的主照明透镜光学联结。在该设备中,附加光源配置在所述印刷电路板上并且与至少一个光导光学联结,所述至少一个光导与规定信号灯的光学部件(optique de feu de signalisation réglementaire)联接。此外,所述光导使由所述附加光源发射的光导向成沿着光束,在使用中所述光束维持在所述牌照板的照明范围之外。
这种设备因此允许安装附加的倒车灯、后雾灯或安全灯,而不明显地改变车辆的后视外观,并因此不妨碍牌照板的可见性。这种附加安装特别地有用于遵循车辆所登记在的国家中的一些的规定。
根据优选的实施例:
-所述光导包括输入部分、弯曲部分和输出部分,所述输出部分与所述牌照板垂直地延伸;
-所述光导的弯曲部分定位在包括印刷电路板的壳体之外,该壳体构造成使得所述光导的弯曲部分和输出部分基本上处在所述壳体外部同时保持在所述牌照板的照明范围之外,以引导输出光束;
-所述牌照板的主照明透镜在输出端处与菲涅尔透镜光学联结;
-所述规定灯的光学部件和所述附加光源从限定用于后雾灯的设备系列(gammes)中选择;
-可替换地,所述规定灯的光学部件和所述附加光源从限定用于倒车灯的设备系列中选择;
-所述牌照板和所述规定灯的照明光源的光照功能和光照特征独立地限定;
-所述光源是LED;
-所述光导的输出部分具有带条纹的输出表面,所述带条纹的输出表面生成与所述规定灯适配的光分布,这些条纹允许光的散射,在使用中所述散射与所述规定灯竖直地和水平地适配。
-所述光导的弯曲部分使所述附加光源的光束沿着基本水平的方向定向,以在使用中使输出光束维持在牌照板上方。
本发明还涉及一种机动车辆,所述机动车辆包括如上限定的具有多个照明功能的后信号设备。
在本文中,修饰词“上”和“下”、“在……上/上方”和“在……下/下方”涉及在标准使用中元件相对于经定位的设备的确定位置。修饰词“竖直”涉及在所考虑的地方处的万有引力方向,并且修饰词“水平”对应于处在与竖直方向垂直的平面中的方向。在附图上,相同或相似的元素由相同的附图标记(参见本发明的相应段落)标记。
附图说明
通过阅读非限制性的详细说明和附图,本发明的其它数据、特征和优点将更加清楚,在所述附图中:
-图1是用于机动车辆的后牌照板的传统信号设备的示意性剖视图(已描述);
-图2是根据本发明的双功能后信号设备的示例的示意性剖视图,根据本发明,所述双功能后信号设备用于后牌照板的照明以及用于防雾灯(作为机动车辆的附加光源)的发射;以及
-图3是图2中的设备的示例的透视图。
具体实施方式
图2的示意图以剖视的方式示出了根据本发明的双功能后信号设备的示例。在该图2上,对于安置在车辆“V”上的平坦的后牌照板的照明借助于LED 3来实施。所述LED 3向下定向(也就是说,朝向车辆“V”的下部竖直地定向),并且固定在水平布置的印刷电路PCB板21的下表面21i上。
此外,LED 3布置在主透镜5上方,所述主透镜使来自LED 3的光束F1的光线R1聚集,这三个零件(板21、LED 3和透镜5)容置在定位于牌照板7上方的壳体11中。菲涅尔透镜6与主透镜5的输出端光学联结,并且使LED 3的从壳体11输出的光束4朝向牌照板7定向。
附加LED 32也固定在PCB板21的下表面21i上,并且向下发射(如同LED 3),所述附加LED的光线R2透入光导52以形成光束F2。所述光导52在连续的三个部分(竖直的输入部分52a、然后弯曲部分52b和最后水平的输出部分52c)中以全反射的形式对LED 32的光进行导向。
有利地,弯曲部52b布置在壳体11的下表面11i附近,并且根据环境而尽可能地接近所述壳体的下表面,以使得光导52不妨碍牌照板7的可见性,所述牌照板因此在所述光导52下方竖直地延伸。在所述光导的输出端处,LED 32的光束F2穿过带条纹的表面62,所述带条纹的表面允许光的竖直散射和水平散射。在该实施例中,安置成与光导52的条纹62相面对的规定灯的光学部件63是后雾灯的光学部件。在该情况下,LED 32发射在红光光谱带中的光。
该双功能后信号设备100(可替换地)可装配有用于倒车灯的附加光源,所述附加光源具有白光的LED 32和倒车灯的光学部件63。安全灯还可与按发射模式和发射频率以及按光谱区间适配的LED协作地安置。
附加LED 32在PCB板21上的安置能够因此通过利用牌照板7的有利的照明安装位置来轻松地安装规定信号灯63。
图3示出了图2的双功能后信号设备100的透视图。在该外表视图上可见:壳体11(所述壳体遮蔽了LED 3和32,参见图2)、菲涅尔透镜6(所述菲涅尔透镜用于牌照板7的照明,参见图2)、光导52的带条纹的输出表面62以及用于给LED供电的电气连接件81。
本发明不限于所描述和所示出的实施例。特别地,可在电路PCB上沿着牌照板的水平边缘安装两个或更多个附加LED。光导的弯曲部分可实施成呈现连续的弧形的形状和/或具有一个或多个斜面的弧形的形状。
另外,波导的端部部分(输入端部分和输出端部分)可根据车辆的后部构型而沿适当的方向延伸。所述壳体具有的形状和尺寸可适用于使所述波导能够保持在牌照板上方。
而且,所述壳体还可安装在下边缘上(此时,光源向上定向)或上边缘上(此时,光源向下定向)。
更一般地,照明壳体安装成使得光导和因此由该光导导向的光束保持在牌照板的视觉范围跨度9(参见图1)之外,重新划分了该板的照明范围的光束4。
此外,所述光源可为LED、白炽灯泡、放电灯泡或卤素灯泡。
