Description

用于生产照明装置的方法以及相应的照明装置
技术领域
本发明涉及照明装置。
不同的实施方式可涉及包括安装在挠性印刷电路上的LED模块系列的照明装置。
背景技术
在现有技术中已知许多不同的照明装置。这些照明装置中的一部分包括照明模块串,例如,安装在例如为挠性印刷电路的相应印刷电路板(PCB)上的LED(发光二极管)模块系列。本领域的技术人员应理解,LED模块串的不同的LED模块典型地借助于互连连接件(“跳线”)来彼此连接。
此外,这些照明装置可被密封以用于外部环境中。具体地,将这些设备根据防护程度的IP(国际保护)等级典型地分类,在所述IP等级中,标准EN 60529中规定的IP代码确定设备的壳抵御固态的或液态的外部媒介的渗透的防护程度。例如,将用于室外用途的照明装置典型地分为等级IP65(抵御喷水的壳)和IP68(抵御浸没影响的壳)中的一个。
例如,借助于灌注过程能够提供所述IP防护,在所述灌注过程中,设备装满例如为树脂或热塑性材料的固态物质。可选地,设备可由防护材料(涂层)覆盖或通过被称为共挤的过程能够将防护材料直接挤压在设备周围。本领域的技术人员应理解,例如为硅树脂、PVC(聚氯乙烯)、聚氨酯等的透明防护材料通常用于照明行业中。
例如,当生产包括LED模块系列的照明装置时,可使用共挤过程,在共挤过程中,直接将防护材料涂覆到具有理论上为无限长度的LED模块串上。然后,切割所述LED模块串以产生预定长度的LED模块串,例如具有从10m至50m不同长度的串。最后,将互连连接件应用到LED串,例如应用到LED串的第一个和/或最后一个LED模块上。
然而,所述防护过程具有若干缺点。例如,为了安装互连连接件,必须部分地移除防护材料,并且必须将互连连接件例如借助于焊接而固定到LED模块中的一个的印刷电路上。
为了避免所述问题,可以将防护材料只应用到已经包括互连连接件的LED串上。然而,所述生产过程具有的缺点是共挤过程低效,这是因为必须独立地制造每个LED串。
发明内容
本发明的目的是提供克服上述缺点的解决方案。
根据本发明,借助于具有在以下权利要求中特别要求保护的特征的制造过程来实现所述目的。本发明也涉及相应的照明装置。
权利要求形成在此关于本发明所提供的技术教导的一部分。
在不同的实施方式中,使用的互连连接件是包括空腔部分的金属互连元件,所述金属互连元件以这种方式在连接件切割时形成至少一个阴连接件。
因此,所述(已经由防护材料覆盖的)串被切成预定长度的串,所述互连元件用作不同LED模块之间的互连连接件,以及用作用于第一个和/或最后一个LED模块的互连连接件。
优选地,所述互连元件具有对称的横向平面,使得当沿着所述对称的横向平面切割互连元件时生成两个阴连接件。
例如,在不同的实施方式中,所述互连元件通过金属板的塑性变形制造。替选地,互连元件能够具有管状的形状,例如为具有矩形横截面的挤出件。
附图说明
现在将仅借助于非限制性实施例、根据附图描述本发明,其中:
-图1a和1b为互连元件的实施方式的立体图;
-图2为通过图1a的II-II平面而得到的互连元件的实施方式的剖面图;
-图3a和3b分别为带有和不带有图1的互连元件的LED串的实施方式的立体图;
-图4为具有涂覆到LED串上的防护材料的LED串的实施方式的立体图;
-图5为分开所述LED串的操作之后的最后一个LED模块的立体图;
-图6为示出了最后一个LED模块连接到阳连接件的立体图;并且
-图7为示出了整个照明装置的立体图。
具体实施方式
以下的说明书阐明了不同的具体细节以提供对实施方式的更深理解。可不带有一个或多个所述具体细节,或可使用其他方法、组件、材料等来实施所述实施方式。在其他情况下,未详细示出或描述已知的结构、材料或操作,以避免对实施方式的不同方面变模糊。
在本说明书中,参照的“实施方式”意在表明,关于所述实施方式说明的特定配置、结构或特征包含在至少一个实施方式中。因此,在本说明书的不同部分可能存在的例如为“在实施方式中”的用语并不一定指的是相同的实施方式。此外,具体的构造、结构或特征可以合适的方式结合到一个或多个实施方式中。
在此使用的参照仅为了方便,并且因此不限定保护的范围或实施方式的范围。
如上所述,两个LED模块之间的互连连接件不是简单的例如为金属针的跳线,而是包括空腔部分的金属连接元件。
例如,图1a、1b和2为所述类型的互连元件10的可能的实施方式的视图。具体地,图1a为从上面的立体图,图1b为从下面的立体图,以及图2为通过图1a的II-II平面而得到的视图。
在此处考虑的实施方式中,互连元件10具有带有翼部的杯状形状;换言之,互连元件10包括底板102和空腔部分104。
具体地,在所述实施方式中,互连元件10关于平面II-II是对称的,换言之,关于对应于横轴的平面是对称的。因此,当沿着横轴将互连元件10切成两半时生成两个完全相同的部分。因此,对称平面II-II(见图2)处的横截面包括两个翼部102和凹部104。
例如,所述类型的互连元件10能够通过例如为铜板的金属板的塑性变形来生产。
在各种实施方式中,底板102用于将连接元件例如通过焊接而固定到两个LED模块上,同时,当互连元件10被切成两半时,空腔部分104生成阴连接件。
作为上述实施方式的替选,也可使用管状形状的互连元件10,例如,带有矩形横截面的挤出件。在这种情况下,侧部中的一个可用作底板102并且其他的三个侧部可对应于空腔部分104。
图3a和3b示出了本文中的互连元件在两个照明模块20a和20b上的安装。
在此处考虑的实施方式中,照明模块20a和20b是完全相同的,并且照明模块20a和20b中的每一个包括:至少一个例如为LED的光源202;以及至少四个金属触点204a、204b、204c和204d。具体地,这些触点的一半——例如触点204a和204b——位于照明模块20的一个端部上,并且所述触点的另外一半——例如触点204c和204d——位于照明模块20的另外一个端部上的相应位置中。例如,在此处考虑的实施方式中,全部的触点和LED位于印刷电路206的同一侧部上。
因此,互连元件10能够用作用于总是使两个触点彼此连接的目的的互连连接件。例如,在此处考虑的实施方式中,第一互连元件10a用于连接触点204a和204c,第二互连元件10b用于连接触点204b和204d。
然后,将防护材料涂覆到LED串上。例如,图4为LED串的立体图,其中,已经借助于共挤过程将防护材料30涂覆到LED串上。
最后,例如准确地沿着互连元件10a和10b的横轴,能够将LED串切成具有预定长度的LED串。具体地,图5为切割的LED串的端子部分的立体图,其中,互连元件10a和10b已经被分成两半。图5也示出了,互连元件的形状使得互连元件内的空腔保持没有防护材料。因此,互连元件的该部分能够用作阴连接件。
例如,图6示出互连元件10a和10b的能够与相应的阳连接件50相接合的部分。例如,在此处考虑的实施方式中,所述连接件50包括两个销502a和502b,两个销502a和502b设置为与互连元件10a和10b对应。
图7示出本文中的整个照明装置的立体图。
本领域的技术人员应领会,上述解决方案具有许多优点,例如:
-对于互连连接件的使用而言,不需要专门的制造工序;例如,不需要除去防护材料以固定互连连接件;
-能够连续地执行用于涂覆防护材料的过程;
-能够简单地并且以低成本生产互连元件;
-互连元件的形状是能够定制的;
-借助于自动的或手工的焊接能够将互连元件固定到LED模块上;以及
-对连接LED串的各个LED模块而言,不需要其他的附加连接件。
当然,只要本发明的原理保持不变,可关于只借助于非限制性实施例阐明的构造的细节和实施方式的形式来以或多或少的程度改变构造的细节和实施方式的形式,从而不会离开如从属权利要求中限定的本发明的保护范围。
