Description
本发明致力于电子部件,更具体地说,致力于一种用于发光二极管(LED)的通用固定器组件。
背景技术
通用照明,特别是照明应用,例如建筑和视频显示的高亮度LED的使用近年来已经增加。典型地,LED照明组件的厂商为用于照明显示的特定LED装置设计定制组件。组件的电气互连和热特性通常被当作次要问题,并且与照明设备(fixture)的机械和美学方面分开予以解决。这会频繁导致LED组件封装产生热和互连的问题。热聚集会损坏LED本身,导致LED的使用寿命变短,或引起对照明设备壳体的损坏,例如弯曲和褪色。
需要的是用于将电气和热连接集成在单个插座中的高亮度LED的标准固定器。其他特征和优点将从本说明书中变得显而易见。所公开的教导延伸到落入权利要求的范围内的那些实施例,而不管它们是否实现了前述需要的一个或更多。

在另一实施例中,本发明致力于一种用于支撑照明设备中的高亮度LED的通用安装组件。安装组件具有固定器部分,其具有限定用于接受印刷电路板组件的空腔的周边侧壁。至少一个支撑构件沿着所述周边侧壁布置以支撑包含LED的印刷电路板组件。多个电接触元件设置在固定器部分中以连接到照明设备的外部导线。导热构件热连通于所述印刷电路板。固定器部分中的孔被布置成以接受所述导热构件。所述导热构件穿过所述孔并进入到用于从所述印刷电路板散热的空间中。
在另一实施例中,本发明致力于一种用于支撑照明设备中的至少一个高亮度LED的安装组件。安装组件具有第一部分和第二部分。第一部分包括框架部分和多个集成的电导体。集成的电导体布置成围绕框架的周边用于连接到布置在PCB上的对应电接触垫。至少一个高亮度LED被安装在PCB上。第二部分保持成能够热接触于所述第一部分。第二部分从第一部分轴向延伸,用于从布置在第一部分内的PCB散热。第二部分具有空腔以将其连接到第一部分,并且具有第二部分的至少一个基座部分以支撑所述空腔内的第一部分。

具体实施方式
只要可能,相同的附图标记在整个附图范围内用来表示相同或相似的部件。
本发明是一种通用LED连接器组件,其接受包含至少一个高亮度LED的传统LED印刷电路板(PCB)。PCB可以是传统结构,或可包括导热层,例如铝。每个LED电路板表示更大图像或光源的部件或像素。LED连接器组件被设计成以独立于使用的实际LED设备。LED PCB用于各种建筑和通用的照明设备、标识和视频显示器、交通信号以及使用高亮度LED的其他应用中。照明设备一般提供壳体或构件,其支撑所述LED光源。该结构提供到LED光源的电力连接,并且提供开口,当光源(或源)通电时光通过该开口发光。当在此使用时,词语“照明设备”表示包括采用高亮度LED的所有通用和专用的LED设备,并且不限于用于建筑照明的照明设备。照明设备的例子包括使用白炽灯泡的轨道安装聚光灯以及使用白炽灯泡或者卤素灯的走道灯。
参照图1-5,LED连接器组件10包括固定器部分12和连接器部分14。通过将接触片22(例如,参见图4)插入到插座24中,固定器部分12可移除地接合连接器部分14。LED PCB组件16被刚性地支撑在固定部分的凹槽26中。LED PCB组件16具有安装在其上的至少一个LED 28,但是如果希望的话,可包括数个LED。例如,用于LED PCB组件的一般结构包括红、绿和蓝(RGB)光的三个LED,用于能够控制地变化组合以实际产生任何颜色的光。对于每种颜色,需要在所述插座中具有另一接触对。例如,RGB将需要布置在LED PCB的外部的六个单独的触头。
散热片18通过内部支撑环42被支撑在固定器部分12中,并且通过圆形的锁闭夹30或其他相似的垫片得以保持在就位。散热片18接触LEDPCB组件16的底侧并且向下延伸到固定器部分12的底边32之下。散热片18在固定器部分12被接合时延伸到并穿过连接器部分14,并且提供用于散出由LED PCB组件16产生的热的热通道。散热片可由任何合适的热导体构成。通过例子但非限定的,散热片材料可以是铜、铝或压铸的锌。在替代的实施例中,散热片18可以是热管。在附图中,散热片18被表示为大致为圆形的圆柱体,其具有扁平的圆形头部58,然而,该形状可根据应用进行变化以便为散热提供另外的裸露表面。例如,散热片18可包括散热翅片、沟槽或其他用于增加散热的形状,本领域内的技术人员将容易认识到此。导热脂或导热垫可以被应用到凸缘或头部58以便提高从LEDPCB 16的传热。
LED PCB组件16优选地在固定器部分12中咬合就位,并且通过连接到接触片22的接触指34的倾斜端部60得以保持。接触指34和接触片22提供导电通道以便引导导线36a-36d穿过接触插座24。弹簧38在散热片18和LED PCB组件16的底部之间施加压缩力,同时给接触指34施加法向力。垫圈40位于锁闭夹30上并将弹簧38保持就位在垫圈40和LEDPCB组件16之间。
参照图3,一个或更多LED 28穿过PCB组件16被电连接到布置在PCB组件16的周边处并且对准用于锁定接合的接触指34的电互连垫44(例如,参见图3)。安装在LED PCB组件16上的每个LED需要两个互连垫44。在图3所示的示例性实施例中,两个LED可被所示的四个互连垫44容纳,尽管描述的PCB组件16仅包括单个LED。当需要容纳所有的LED时可增加更多的互连垫44。同样地,接触指34和插座24的数量与互连垫44的数量对应。可布置在所述周边的触头数量仅由PCB组件16的几何形状限制。另外的互连件可用于连接或控制一个或更多LED设备(未示出)的导线。典型的LED PCB组件包括LED光源,其被安装在电绝缘顶层的复合基片例如FR4或云母板上,可选择包括用于改善热传导的金属底层,例如铝或铜。卡口接线片20可选择形成在固定器部分12上,用于将LED连接器组件10连接到用户的照明设备的透镜组件上,或LED连接器组件要安装在其中的其他构件上。用于LED连接器组件的替代连接设备可包括螺纹连接件或咬合配合连接件(未示出)。
在图6所示的另一实施例中,散热片18可通过内部支撑环42的模制架部分46,其替换上述实施例中的锁闭夹30和垫圈40,被保持在固定器部分12中。用于保持散热片18的位置的另一结构示于图7中。在该结构中,闭锁边48接合散热片18的边缘部分50。边缘部分50通过弹簧38保持抵靠闭锁边48。该结构通过消除例如垫圈和夹子而具有更少的部件,并且因此更容易组装以及集成到照明设备。PCB组件浮设(float)在接触指34和散热片18之间。接触指34施加向下的力,散热片18施加相反的力以将LED PCB组件16保持就位,也就是,散热片18向上推靠LED PCB组件16。
在本发明的范围内可以可选择地不要连接器部分14。再次参照图4,接触片22可予以去除并且用焊接凸片或压配合凸片咬合连接器进行替换。通过直接连接到另一PCB(未示出)或者没有被支撑而将不需要连接器部分14,连接器部分14可由基片52(例如,参见图8)替代。在如图8所示的实施例中,替代的LED连接器组件10a包括通过焊接或机械紧固件被连接到基片52上的PCB固定器部分12。多个连接器端子部分54从固定器部分12延伸过所述基片。外部接线(未示出)被连接到连接器端子部分54以给LED和LED连接器组件10固定在其中的照明设备或装置的相关控制或通信设备供电。散热片18还突起到基片52之下并且被暴露到下面的气室中用于散热。所述气室可包括由风扇驱动以增加或加强散热片18的散热特性的气流。LED PCB组件16咬合就位到固定器10a中。
接下来参照图9,连接器部分14可选择地安装在基片52上,并且固定器部分12插入到连接器部分14中,端子部分54从基片52的相对侧延伸,并且散热片18在所述基片之下突起,如上所述。
接下来参照图10和11,LED连接器组件10的替代实施例具有修改的散热片18,其具有沟槽形状用于为散热提供另外的表面区域。在一个实施例中,散热片18设计有补充的外部环,其类似于传统的卤素灯泡例如在反射器组件上具有外部环的GU10或MR16型的标准灯泡,以允许LED像素组件10直接替换传统的灯泡。可替代地,所述散热片的后部可车出螺纹(未示出)以装配到带螺纹的照明设备中。LED PCB组件16倚靠在从散热片18的外半径向内径向突起的单独沟槽部分31的顶部之上。引线36具有弯曲触头21,其可被插入到接触承载部分13并且穿过由沟槽部分31限定的通道36向下延伸。触头和/或引线36的数量取决于安装在LEDPCB组件16上的LED28的数量。对于每个LED28,LED可具有两个引线36,或多个LED可共用通用的接地线或中线。可使用各种LED互连件,示于附图中的引线的数量仅是示例性的,并不是用来限制本发明的范围。接触承载部分13滑入散热片18中并抵靠LED PCB组件16并且锁入到凸缘部分11之下的位置中。闭锁件15将LED PCB组件16固定就位,并且迫使电触头部分21抵靠接触垫用于牢固的电接触。闭锁件15还保持LEDPCB组件16和散热片18之间的热接触。在一个实施例中,闭锁件15包括台阶部分19以接收多个厚度的LED PCB组件16。可选择的透镜部分17和透镜连接器27可被插入到LED的连接器组件10以增强安装在其上的LED或LED28的光学特性。唇部29形成在凸缘部分11中并通过弹簧38(例如,参见图4)施加的弹力接合透镜部分17以将所述透镜部分17保持就位。在一个实施例中,凸缘部分11可包括孔41以提供用于改进散热的空气流动通道。
