Description
技术领域
本发明涉及车辆用多功能灯,尤其涉及一种一个光源透过光调节装置向多个灯照射光的车辆用多功能灯。
背景技术
车灯通常由前灯与后灯等构成,前灯由安装在车辆前侧的前照灯、雾灯、方向指示灯构成,后灯则由安装在车辆尾部的方向指示灯、刹车灯、尾灯、倒车灯等构成。
前灯与后灯向车辆前方及后方照射各灯发出的光,夜间行驶或雷雨天等能见度差时用于确保驾驶员的视野,或向其他车辆的驾驶员提示本车辆的转向方向、制动、倒车等情况。
现有车灯中,构成前灯与后灯的前照灯、雾灯、方向指示灯、刹车灯、尾灯及倒车灯分别为独立的模块,这些模块各自使用光源。
因此,各光源的寿命不尽相同,驾驶员需要周期性更换已达到寿命的光源,不仅繁琐还会产生更换费用。并且,由于设置于各模块的光源都具有一定大小,因此无法实现各模块的小型化。

具体实施方式
以下参照附图详细说明本发明的优选实施例。首先,需要注意的是在对各图的构成要素添加附图标记方面,即使相同的构成要素出现在不同的附图上也尽可能添加相同的附图标记。并且在说明本发明时若判断认为对相关公知结构或功能的具体说明可能对本发明的主题造成混淆,则省略相关详细说明。另外,以下将说明本发明的优选实施例,但本发明的技术方案并不限定或限制于此,所属技术领域的技术人员可做多种变形实施。
参照图1至图4,根据本发明优选实施例的车辆用多功能灯1包括车辆用灯部300,其数量为两个以上,分别包括反射器310;以及光源部100,其具有照射光的光源110、与所述光源110连接并反射所述光源照射的光的光源部反射体120以及部分阻断或向多个路径透过从所述光源110照射后被所述光源部反射体120反射的光的光调节部130,向所述车辆用灯部300照射光。
车辆用多功能灯1还可以包括将从光源部100透过的光传递到车辆用灯部300的光传递部200。
参照图2,光调节部130能够向多个路径透过一个光源110照射的光,通过部分阻断使得仅照射所需的部分光。
参照图3,光调节部130可以是作为模式变化液晶的LCD(LiquidCrystalDisplay)132。LCD132是采用分子排列随电压改变的液晶的显示装置。通过这种性质,可以在光源110照射光时根据驾驶员对灯的操作施加电压,以调节使光透过的路径与阻断光的路径。
在此,液晶(liquidcrystal)类似于具有某种程度的规律性的液相(liquidphase)。例如,加热融化时成为具有双折射等异向性的液相的固体。液晶具有双折射或色变等光学特性。结晶具有规律性,物质的相近似液体,由于具有这两种性质而称为液晶。
液晶根据分子的排列方式分为三类。仅轴的方向一致的称为向列相(nematic),具有预定方向的分子形成层的称为近晶相(smectic)。另外一种是轴一致但轴的方向不同的胆淄醇(cholesteric)。
另外,LCD132可包括光透过的四个路径。虽可以根据光源110的强度进行调整,但向四个路径分散光为宜。
LCD132的形状还可以根据外壳170的形状进行调整,其形状可以是圆形或多边形。
图中虽未示出,但光调节部130可以是具有遮板功能的遮蔽器件。为了根据驾驶员的操作阻断或透过光源110的光,可通过打开或关闭遮板使光透过或阻断。可以在一个遮蔽器件上安装多个遮板使得光向多个路径透过,阻断不使用的部分。
所述光源部100还可以包括散发或阻断所述光源110发出的热的散热防止部。长时间使用光源110的情况下将产生大量热,当将LCD132用作光调节部130时,光源110发出的热传递到LCD132时可能造成LCD132的误运行或耐久性下降。因此,其目的在于将光源110发出的热散发到光源部100外部或防止传递到光调节部130。
参照图3至图4,所述散热防止部可以是设置于所述光调节部130与所述光源110之间的阻热滤光器140。阻热滤光器140可以由聚乙烯醇缩丁醛(PVB:Polyvinylbutyral)构成。除此之外,已知现有技术中能够使光透过且阻热的都可以进行替换。
并且,散热防止部可以是设置于所述光源110的散热板。所述散热板设置于光源110,可以吸收光源110发出的热并散发到光源部100的外侧。也可以根据光源110的种类同时采用散热板与阻热滤光器140。
所述光源部100还可以包括使从所述光调节部130向所述多个路径透过的光透过,且反射从所述光调节部130脱离所述多个路径透过的光使得向多个路径透过,以转换光的传播方向的光调节滤光器150。其作用是在光调节部130无法完全阻断光时透过光调节滤光器150阻断和反射光,进一步防止光向多个路径之外的其他地方透过。
参照图7,所述光调节滤光器150可以是具有光透过率与反射率的半反射镜滤光器152。通常,半反射镜滤光器152的反射率与透过率各占一半,实际会因波长而异,另外还有吸收部分。通常,半反射镜滤光器152是在玻璃表面上涂布金属氧化物构成的,半反射镜滤光器152可以通过真空蒸镀来镀铝形成。反射区间与透过区间可以因透过光源部110的光与车辆用灯部300的位置而异。
光源部100还可以包括设置于光调节部130前方,通过多个路径将从光源部100透过的光传递到所述车辆用灯部300的光导器件160。
通常,光导器件160使从端部照射的光沿其长度传播,显示出多种模样与颜色的照明效果。为了聚光从所述光源部100发出的光,入口部的断面为多边形或圆形,前面部中间可以沿长度方向形成用于扩散光的一个以上的半球形凸出部。所述凸出部形成有用于提高光的发射率与传输率的台阶,为了调节出光方向,出口部可以是多个分割的断面形状。
光导器件160抑制光的折射、引导全反射,从而能够防止向车辆用灯部300传递的光量损失。光导器件160由不褪色聚氨酯树脂、硬化剂、不褪色聚氨酯树脂固化促进剂及固化剂固化促进剂组成的组合物,整个长度范围都能够发挥均匀照度。
光导器件160上的透过光的路径数量可以因车辆用灯部300的数量而异,光导器件160可以包括光透过的四个路径。考虑到各车辆用灯部300的大小与外壳170的大小,采用四个路径为宜。
所述车辆用多功能灯还可以包括内置构成所述光源部100的所述光源110、所述光源部反射体120、所述光调节部130、所述散热防止部、所述光调节滤光器150及所述光导器件160形成一个模块的外壳170。通过使光源部100的构成要素形成一个模块实现小型化,使用时不受车辆的车型或形态的限制。
可采用耐热性强、内侧的光反射率高的外壳170。
光源部反射体120的形态与一般反射器的形态相同。可以是一般抛物线反射镜的形状被削去末端后形成的圆锥形凹陷形状,也可以是曲面形、半球形、抛物线形状。材质通常可以是团状模塑料(BMC:BulkMouldingCompounds)或研磨的铝,也可以是耐热性优于BMC的铝。
参照图5与图6,将从光源部100透过的光传递到车辆用灯部300的光传递部200可以是光纤210。
光纤210分别与光导器件160及车辆用灯部300连接,将透过所述光导器件160的光传递到所述车辆用灯部300。光纤210与光导器件160可以通过连接部180连接,可以连接多个光纤210。
光纤210是由透明度极高的石英玻璃制成的粗度为1/100㎜左右的细线。光纤210的中心具有折射率高的纤芯(core),折射率小的包层(cladding)包覆纤芯,整体被合成树脂包覆。从光纤210纤芯的一侧端部入射的光在所述纤芯与所述包层的分界面发生全反射并继续传输。
光纤210通过内部全反射,将光从一侧传输到另一侧。即使光纤210弯曲,光也能够通过内部全反射沿内侧壁面反射继续前进。光纤210可以随意引导光的前进路径,因此能够广泛用于装饰用灯或内视镜、光通信等。
光纤210本身不发光,只是起到传输光的作用。因此,当把光源部100发出的光通过多束股光纤210连接到设置于前方的扩散用透镜220的情况下,能够起到与具有灯丝的光源相同的作用。
并且,在去除扩散用透镜,以束状使用光纤210的情况下能够形成点光源形态,因此能够起到与LED光源相同的作用。
通过光传递部200照射的光被反射器310反射。
反射器310的材质通常为团状模塑料(BMC:BulkMouldingCompounds)或研磨的铝,也可以是耐热性优于BMC的铝。
反射器310的形状可以是圆锥形、曲面形、半球形、抛物线形等形状,其形态可根据所需光的传输方向机光量变更。
所述车辆用灯部300还可以包括设置于所述反射器310的前方,使所述光源部100照射的光折射透过的透镜320。
所述车辆用灯部300与用于所述光源部的光透过的多个路径的数量可以相同。
以上各实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照上述各实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对上述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换。
因此,以上用于举例说明,并非对本发明进行限定,本发明所属领域的普通技术人员在不超出本实施例的本质特性的范围内,还可以进行以上未提及的多种变形及应用。例如,实施例中具体出现的各构成要素可变形实施。并且,有关这些变形与应用的差异点应视为包含于本发明的技术方案内。
