Description

发光二极管灯泡
技术领域
本发明涉及光源，特别是涉及采用发光二极管(LED或LEDs)的光源，且特别是涉及用于汽车领域中的光源，如头灯、尾灯、停车灯、雾灯、转向信号灯等。更加特别的是，本发明涉及被整装以获得工业上接受的可互换性的光源。
背景技术
在过去，绝大多数汽车光源涉及使用白炽灯泡。尽管性能良好并且廉价，但是这些灯泡具有相对较短的寿命，并且，自然的是，所使用的细灯丝由于受到振动总是易于发生断裂。
近来一些应用，特别是停车灯的应用，已由发光二极管所取代。这些固态光源具有难于置信的寿命，在100,000小时左右，并且不受振动故障的影响。然而，这些发光二极管光源已被硬接线进它们适当的部位，由此增加了安装成本。因此，若能够提供具有如白炽光源的安装简易性的发光二极管光源，那么将是本技术领域中的一个进步。若能够提供达到工业上接受的可互换标准以更换前述白炽灯泡的发光二极管光源，那么将是本技术领域中的另一个进步。
发明内容
因此，本发明的一个目的在于避免现有技术中存在的缺点。
本发明的另一个目的在于增强发光二极管光源。
本发明的又一个目的在于提供可更换的发光二极管光源。
在本发明的一个方面中，这些目的可通过一种发光二极管光源实现，所述发光二极管光源包括具有基座的套壳，中空芯部从基座中伸出，所述芯部大体上呈锥形。中心热导体位于中空芯部内的中心并且具有连接在一个端部上的第一印刷电路板，和被装配到第二端部上的第二印刷电路板。第二印刷电路板具有至少一个操作地固定于其上的发光二极管。多个导电体具有被附接到第二印刷电路板上并从第二印刷电路板中延伸出的近端和被附接到第一印刷电路板上的远端。盖被装配在第二印刷电路板上，并且散热器被附接到基座上并与第一印刷电路板热接触。散热器具有带有终止成为多个指部的直立侧壁的底部，所述指部成形用以覆盖在基座的上表面上面。
该发光二极管光源是完全整装的并且能够组装到现有反射器上。通过例如已在汽车领域使用多年的标准插头和插座装置提供必要的电连接，由此消除对硬连线和常规电路的需要。
附图说明
图1是本发明的一种实施方式的分解透视图；
图2是本发明的一种实施方式的剖视图；
图3是本发明的一种实施方式的相类似的剖视图，即将图2所示实施方式旋转90°后得到的剖视图；
图4是本发明的一种实施方式的顶部透视图；和
图5是本发明的一种实施方式的底部透视图。
具体实施方式
为了更好地理解本发明，连同其它和进一步的目的、优点及其性能，结合上述附图并参考以下公开内容和所附技术方案。
下面，更加详细地参考以下附图。图1中示出发光二极管光源10包括具有基座14的套壳12。中空芯部16从基座中伸出，所述芯部大体上呈锥形。中心热导体18位于中空芯部16内的中心并且由适当的导热材料例如铜制成。优选地，中心热导体18被压配合进入芯部中。第一印刷电路板20被安置在基座14中，并且第二印刷电路板24被装配到中心热导体18的第二端部26上。印刷电路板20与柱18隔开，使得印刷电路板24产生的热通过柱18被直接传导至散热片42。在安装第二印刷电路板和铜垫圈27a被安置在第二印刷电路板上面之前，硅酮密封垫片27被施加到端部22上。第二印刷电路板具有至少一个操作地固定于其上的发光二极管28。在本发明的一种优选实施方式中，在印刷电路板24的周边附近固定有8个发光二极管28。若发光二极管光源10被用作尾灯，那么全部发光二极管可以是红灯发射体。另一种选择是，根据所需的效果，可以使用其它不同颜色的发光二极管。
设置四个导电体30，其近端32被附接到第二印刷电路板24上并从第二印刷电路板24中延伸出且其远端32被附接到第一印刷电路板20上。盖36被装配在第二印刷电路板24上，并且散热器38被附接到基座14上并与第一印刷电路板20热接触。散热器38具有带有终止成为多个指部44的直立侧壁42的底部40，所述指部44成形用以覆盖在基座14的上表面46上面。散热器38优选由用于热辐射目的的经阳极黑化处理的铝(blackened-anodized aluminum)制成。
借助热油泥39，例如Thermagon 304实现散热器38和第一印刷电路板20之间的热接触。
由于整个发光二极管光源10围绕轴线大体上对称排列，因此若沿轴线排列的所有部件被调节以具有适当的取向，那么非常有助于组装操作。
在这点上，发光二极管光源10具有成形分别带有第一和第二端部50，52的中空芯部16，并且所述第一端部50设有键槽54，并且中心热导体18分别具有第一和第二端部56，58，且第一端部56具有相匹配的芯部键54a。该配合的键槽和键，其可包括在中心热导体上的扁平壁和在中央芯部中的相配合的平直壁，确保了中心热导体18相对于中空芯部16的适当定位。
同样，中心热导体18的第二端部58设有键60且第一印刷电路板20具有相匹配的键槽60a。在具体实施方式中示出键槽60表现为双扇形开口的形式并且键60与其相一致。显然，虽然考虑到向散热片42的热量分布性能，双扇形是优选的，但是也可以使用其它形式的键槽和键。
为了保持导电体30之间的对正，在第一印刷电路板20和第二印刷电路板24之间，中心热导体18具有定位在其周围的导电体对准器62。对准器62最佳如图2和3所示并且四个导电体30的适当定位。
在本发明的一种优选实施方式中，第二印刷电路板24通过自攻螺钉64被固定到中心热导体18上。如有必要，第二自攻螺钉可被用于将第一印刷电路板20固定到中心热导体上。如有必要，还可使用被压配合进入中心热导体18中的铜插头。在另一种可选实施方式中，可使盖36金属化，并且盖36、垫圈27a和螺钉64可被组合成单个部件，从而减少部件数量并且获得与柱18的更好的热接触。
自攻螺钉的使用增强了与铜柱的热接触并且去掉了二次机加工操作。
中空芯部16被设置在其下端处，即最接近基座14的端部处，具有用于接合反射器中的适当开口的多个凸缘66并且在其上端部具有金属化的光学部件68。该金属化的光学部件68可以是装配在中空芯部16上面的单独的金属构造，或者该金属化的光学部件68可以是直接喷镀在塑料芯部上的金属层。
通过包括三个嵌入模内的电触点72的插头70提供与发光二极管的外部电连接。因此，与第一印刷电路板20的连接仅需要七个焊点，三个嵌入模内的电触点72的连接和四个导电体30的连接。反射器垫片80围绕芯部16进行设置，且0形圈82被放置在基座14中，从而提供环境密封。
因此，提供一种整装的并且易于进行安装和可更换的发光二极管光源，对这种发光二极管光源的需求将上升。
虽然上面已对在此被认为是本发明的优选实施方式进行了描述和说明，但是对于本领域的技术人员明显的是，在不偏离由所附技术方案限定出的本发明的范围的条件下，可对本发明作出多种变化和变型。
