Description

具有光传输光学系统的车辆照明组件
引言
车辆照明组件被配置为执行一个或多个指定的照明功能。例如，除了远光和近光大灯功能外，典型的大灯组件还装有日间行车灯和转向信号功能。通常要求外部车辆照明符合某些可见性标准，例如，在照明组件的特定水平角度和垂直角度范围内，行人必须能够看到前转向信号灯。因此，车辆大灯组件的结构设计可能性受到限制。
发明内容
本文公开了一种用于车身的照明组件。还公开了一种包括车身和照明组件的车辆。照明组件可包括细长的光传输光学系统，例如具有内部光导光学处方的矩形丙烯酸管。光传输光学系统被配置为引导来自位于车辆/照明组件的外侧位置的光源的入射光，其中这种反射朝向内侧位置发生。由于结合了光传输光学系统，例如但不限于前大灯组件，其中引导的光对应于来自车辆转向信号功能的光，因此可以实现照明组件的更积极的前扫或前裹配置。
示例性实施例中的照明组件可与具有外侧和内侧端的车身一起使用，即，在车身的纵向轴线的外侧/更远和内侧/附近。照明组件的壳体可连接到车身。照明组件还包括灯具、光传输光学系统和外透镜。灯具靠近外侧端定位，并且具有多个光源，例如一排四个发光二极管，其具有一个侧射和三个回射反射器。光传输光学系统连接到灯具，并配置为将来自光源的光引导到内侧端。外透镜连接到壳体，使得灯具和细长的光传输光学系统由连接的壳体和外透镜封装。
光传输光学系统的远端靠近外透镜的远端定位。一个或两个远端包括表面光学器件，该表面光学器件配置为使引导的光分布通过远端。表面光学器件可以是预定的光散射图案，其被模制到光传输光学系统中，施加到光传输光学系统上或由光传输光学系统限定。
在非限制性示例实施例中，光传输光学系统的远端的表面法向矢量布置在外透镜的远端的表面法向矢量的约30-60度内。或者，当相对于水平方向观察照明组件时，光传输光学系统的远端可以相对于水平方向法向/正交地布置，并且外透镜的远端可以是大约45度到水平。
光源可以可选地包括一组发光二极管。在示例性实施例中，四个发光二极管排成一排，具有三个内侧LED和一个外侧LED。三个内侧LED可以包括相应的回射反射器，并且外侧发光二极管可以包括侧射反射器。
在一些实施例中，外透镜的外表面与照明组件的内侧端处的壳体之间的距离可以是至少5厘米，使得外透镜在内侧端处突出或伸出远离车身。以这种方式，外透镜的预定表面区域最终在照明组件的内侧端照射。
在各种实施例中，光传输光学系统连接到一些或所有光源，包括在一个实施例中的一个光源和另一个实施例中的所有光源。
光传输光学系统可以体现为例如由丙烯酸或其他合适材料构成的管。该管具有提供预定光学处方的内表面，例如一系列表面光栅，或另一表面特征件，其被配置为沿着光传输光学系统的长度引导光。
根据可能配置的车辆包括车身和照明组件，后者连接到车身的前端并具有外侧和内侧端。在该特定实施例中，照明组件包括连接到车身的壳体，以及配置为在车辆上提供转向信号照明功能的灯具。细长的管状光传输光学系统连接到灯具，具有靠近内侧端的远端，并且被配置为将来自灯具的一个或多个光源的光从外侧端引导到远端，例如至少一些引导的光通过光传输光学系统的远端发射。灯具和光传输光学系统由壳体和外透镜封装。外透镜在内侧端处从车身向外伸出，因此不与车身齐平。
通过以下结合附图对实现本公开的最佳模式的详细描述，本公开的上述特征和优点以及其他特征和优点将变得显而易见。前述发明内容描述了本文所述的一些新颖概念和特征。此外，本公开明确地包括本文呈现的各种元件和特征的组合和子组合。

本公开可以进行各种修改和替换形式，并且已经通过附图中的示例示出了一些代表性实施例，并且将在本文中对其进行详细描述。然而，应该理解，本公开的新颖方面不限于附图中示出的特定形式。相反，本公开旨在覆盖落入由所附权利要求限定的本公开的范围内的修改、等同物、组合、子组合和替代。
具体实施方式
参考附图，其中在几个视图中相同的数字表示相同的部件，图1所示的示例性车辆10具有车身12和发动机罩13，车身12具有纵向中心线/轴线11。车辆10包括与路面16滚动接触的车轮14，并且还包括照明组件20，照明组件20配置为引导光从外侧端26到照明组件20的内侧端28。如本文所用，术语“外侧”指的是相对于车辆10的正常前向驱动配置的侧面或侧向位置，而“内侧”指的是从外侧位置径向向内的位置，即，更靠近车辆10的纵向轴线11的位置。
照明组件20具有外透镜22和壳体25，壳体25连接到车身12。在一些实施例中，外透镜22可由透明或通透的丙烯酸材料，并且壳体25可以由不透明的注模塑料构成，但是在其他实施例中可以使用不同的材料。在示例性大灯应用中，照明组件20牢固地安装到车身12的与发动机罩13相邻的装饰面板件24上。尽管为了说明简单而从图1中省略，但是在安装照明组件20之后，可以用另一个装饰面板件、格子形工件或其他结构覆盖装饰面板件24，以在车辆10的前端18处提供成品装饰性外观。
车辆10是照明组件20的示例应用，其中照明组件20靠近前端18定位并且被配置作为前大灯组件。然而，照明组件20不一定限于一般的机动车辆应用或特别是车辆应用。需要改进特定照明效果的侧面可见性的其他移动平台，例如前转向信号序列，可以在适当缩放和配置用于特定应用时受益于照明组件20的使用。
与图1的示例性前大灯/转向信号配置一致，除了包含近光和远光照明功能(未示出)之外，照明组件20还可包括具有如图2中最佳示出的多个光源30A、30B、30C和30D的灯具30，以及如下参照图2-5C详细阐述的细长光传输光学系统32。光传输光学系统32被配置为引导(即，内部反射和导向)来自灯具30的发射光，例如执行前转向信号功能的交替或闪烁光图案。光从照明组件20的外侧端26朝向内侧端28馈送到光传输光学系统32中，内侧端28位于前端18附近。
由光传输光学系统32导向的光最终被引导通过外透镜22的基本平坦/平面的远端表面29，远端表面29以如下方式配置，发射光(图2的箭头L)对于位于前端18附近并且相对于其侧面定位的人类观察者来说容易看到。举例来说，在参考位置的校准角度范围内(例如，与车辆10的前端18相交的垂直平面的±45°)，前转向信号功能可见，如从相对于车辆10的前端18的侧面位置(即，靠近前端18的侧视角)可见。在从相同观察位置与照明组件20相交的水平面的±15°内(即，当在前端18的侧面附近观察车辆10时的上/下视角)可能需要可见性。可见性标准的范围/值可以因国家而异，因此可以在本公开的范围内对这里描述的配置进行修改以满足这些标准。
在说明性场景中，当车辆10准备执行右转弯时，行人可以定位在与转弯方向相反的人行道上，即，在车辆10的操作员的左手边。行人必须能够在上述角度范围内观察转向信号。由于行人的位置在车辆10的相对的一侧，同时灯具30用于照明组件20及其外透镜22的积极地前扫/前裹的变化，如图1中箭头A所示的前扫方向，因而在规定的角度范围内，行人可能无法完全看到转向信号照明。然而，使用光传输光学系统32引导一些转向信号照明到达并穿过暴露的远端表面29使得这种造型成为可能。
图2描绘了图1的照明组件20，其带有额外的内部细节。可以按序列单独控制光源30A-D以提供预定的闪光速率。因此，尽管为了清晰起见图中进行省略，但是车辆10可以包括电子控制单元，其接收信令请求，例如，响应于操作者控制或自主控制的激活，并且响应于信令请求，操作开关或其他硬件，用于将各个光源30A-D连接到电池或其他电源。光源30A-D可以实施为发光二极管(LED)，例如，如图所示并排排列成行的四个LED。当光源30A、30B、30C和/或30D通过相应的切换功能单独激活时，发射的光被馈送到光传输光学系统32中并且沿着光传输光学系统32的长度被引导/导向朝向内侧端28，如箭头LL所示。
光传输光学系统32可以体现为丙烯酸或其他合适材料的连续矩形或圆形管，其内表面37(参见图4)与专用光学处方一体地形成或处理，例如，足以沿光传输光学系统32的整个长度反射、导向或以其他方式引导光的纹理透镜图案或表面涂层。引导光(箭头LL)最终在内侧端28处离开光传输光学系统32，发射光在图2中以箭头L表示。
在另一个说明性实施例中，每个光源30A-D可以具有相应的回射反射器33B或侧射反射器33S，即，抛光的抛物面反射器可以沿基本上平行于图1所示的车辆10的纵向轴线11(回射)的方向定向或者相对于轴线11(侧射)成角度。在一个示例性实施例中，最外侧光源，即光源30A，可以包括相应的侧射反射器33S，而三个内侧光源30B-D可以包括回射反射器33B。
如图3中最佳所示，照明组件20被配置成使得在外透镜22的外表面220和远端处的装饰面板件24之间提供预定的间隔距离(D)，距离(D)足够大以使远端表面29具有必要的表面区域，并且因此，每个专用的照明标准具有最佳的侧面可视性。例如，在一些实施例中，内侧端28处的距离(D)可以是至少5厘米，其他可能的距离(D)足以确保外透镜22从壳体25突出/不与在内侧端28处的壳体25或者装饰面板件24齐平。
图3中还示出了光传输光学系统32的远端33。图3的透视图是在上述场景中观察者可见的轮廓，即，照明组件20是左前/驾驶员侧大灯，并且观察者位于车辆10的左前/乘客侧的一侧。在这种情况下，远端表面29暴露于观察者而不是朝向车身12逐渐变细。远端表面29和光传输光学系统32的远端可包括表面光学器件35。表面光学器件35提供另一光学处方，并且可以是由光传输光学系统32和/或外透镜22限定的预定表面图案的形式，其中表面图案将光导向上述观察者。
图4从侧视图的角度描绘了图1-3的照明组件20，即从图1的车辆10的左前/驾驶员侧拐角的角度看。如上所述，光传输光学系统32可以体现为细长管，其可以具有矩形横截面或其他合适的几何形状。光传输光学系统32具有内表面37，其提供合适的光学处方，例如表面光栅、透镜特征或另一种光分布图案。从光传输光学系统32的远端表面39延伸的表面法向矢量V1可以设置在外透镜22的远端表面29的表面法向矢量V2的30-60度之间的范围内。或者相对于沿着车辆10的纵向轴线的水平面P1，远端表面39的平面P2可以正交地布置/90°(θB)，并且远端表面29的平面P3可以布置在与水平面成45°(θA)的角度。可以在本公开的范围内使用其他相对布置，以在暴露的远端表面29处提供期望的照明效果。
图5A-C描绘了用于图1-4的所公开的照明组件20的三个可能的示例性照明序列，或者更准确地说，用于照明光源30A-D和与其连接的光传输光学系统32。在图5A中，细长光传输光学系统32仅连接到光源之一，例如光源30A。因此，仅在光源30A通电时，光可以在该实施例中被引导通过光传输光学系统32。例如，当在图1的车辆10上执行左转信号操纵时，光序列可以是如图5A中编号1、2、3、4，即，在那个特定的序列中的光源30D、30C、30B和30A的照明。一旦光源30A被照射，如上所述，光沿着光传输光学系统32的长度被引导并通过光传输光学系统32。
在图5B和图5C中，光传输光学系统32连接到所有光源30A-D，因此一旦启动相同的转向信号操纵，光就经由光传输光学系统32被引导到远端表面29。也就是说，无论有多少光源30A-30D通电，光沿着光传输光学系统32被引导到远端表面29，从而照射图3的远端表面29。图5B提供了当没有光源30A-D通电时经由单独的光源130(例如，另一个LED、白炽灯或卤素灯泡)照射光传输光学系统32的附加选项。
使用上述照明组件20，可以光学地分配补充照明以提高可见性，从而实现更积极的前扫造型。这种造型还可以改善照明组件的空气动力学性能。在现有闪光速率要求内控制光激活序列的能力，加上启用的前扫造型，还允许具有更动态的环裹或前扫外观的转向信号。鉴于前述公开内容，本领域普通技术人员将理解这些和其他可能的优点。
详细描述和附图或图是本公开的支持和描述，但是本公开的范围仅由权利要求限定。虽然已经详细描述了用于执行所要求保护的教导的一些最佳模式和其他实施例，但是存在用于实践所附权利要求中限定的本公开的各种替代设计和实施例。
