Description

嵌入式灯具
技术领域
本发明涉及一种嵌入式灯具,其包括壳体、支撑至少一个发光二极管的电路板,以及由透明材料形成的覆盖物。确切地说,本发明涉及这样一种嵌入式灯具,其用于家具板中的安装开口。
背景技术
用于家具板的嵌入式灯具是已知的,它们可以安装在家具板中的安装开口中。通常,它们安装在家具板中,其中灯具前部向下,从而照亮家具板下方的区域。例如,这样的嵌入式灯具可以应用于展示橱柜、台架等。
发明内容
本发明的一个目标是实现可以尤其易于组装的嵌入式灯具。
根据本发明,该目标是由起初提到的那种嵌入式灯具来实现的,其中所述覆盖物包括透镜单元,所述壳体用于容纳所述电路板和所述透镜单元,所述覆盖物包括用于将其锁定在壳体上的锁定部件,并且所述覆盖物包括用于将嵌入式灯具固定在家具板中的安装开口中的安装弹簧。
由于所述覆盖物包括用于将其锁定在所述壳体上的锁定部件以及用于将其固定在安装开口中的安装弹簧,因此可以在将所述电路板插入所述壳体中之后不使用工具而是通过将所述覆盖物锁定在所述壳体上来固定所述覆盖物,并因此,同时提供了安装弹簧。这是尤其有利的。首先,无需其他安装部件即可将所述覆盖物固定在所述壳体上。其次,可能提供例如由金属制成的刚性壳体,因为例如用透明塑料等形成的覆盖物可以提供柔性锁定部件以及柔性安装弹簧。金属壳体尤其有利,因为它可以将高功率发光二极管中的余热耗散。
从属权利要求书中指明了本发明的有用细节和进步点。
附图说明
现将结合各图来描述本发明的优选实施例,在图中:
图1为根据本发明的嵌入式灯具的示意透视分解图;
图2为组装好的嵌入式灯具的示意透视截面图;
图3为具有孔径附接件版本的嵌入式灯具的示意侧视图;以及
图4为孔径附接件的示意截面图。
具体实施方式
图1示意性地示出了具有壳体12、电路板14、O形环密封件形式的密封件16、覆盖物18以及覆盖环20的嵌入式灯具10的分解图。还示出了用于供电的带线缆插头22。
图2所示为安装好的状态下的灯具的略微倾斜透视的截面图,其中电路板14被插入壳体12中并且在壳体的底部24邻接。覆盖物18布置在电路板14前方,其中密封环16布置在壳体12与覆盖物18之间。还示出了覆盖环20。
壳体12为杯形,具有底部24以及从底部24朝向灯具前部直立起来的圆周壁或侧壁26。该壳体基本上为圆形。侧壁26基本上为圆柱形。壳体12由金属制成,例如,为铝铸模壳体。在前缘处,凸缘部分28从侧壁26直立起来,其用于当将嵌入式灯具10插入安装开口中时限定插入深度。此外,冷却结构30,例如冷却肋片,在侧壁26外部形成。
此外,在侧壁26外部,形成了用于覆盖物18中的安装弹簧34的容纳轮廓32,所述容纳轮廓向内凹陷并且相对于底部24横向延伸,还在其他圆周位置处形成了用于覆盖环20中的咬合突耳38的容纳轮廓36。
此外,用于锁定覆盖物18中的咬合销42的咬合轮廓40形成为从侧壁26内部突出。
最后,在侧壁26内部提供对齐轮廓44,用于与电路板14的圆周边缘处的互补对齐轮廓46互相作用。
圆形,近似圆盘形的电路板14在前部配备有发光二极管(LED)48,并且所述电路板配接到壳体12的截面。电路板14中侧向突出的一部分,支撑住插头连接器,所述插头连接器在安装好的状态下布置在壳体12中相应的开口中并且允许从外部插入插头22。
如图2所示,在安装好的状态下密封环16位于壳体12的圆周壁26内侧的肩突(shoulder)上。该肩突形成密封面。相对的密封面由从覆盖物18外部突出的环形突出物形成。
图2还示出了咬合销42,所述咬合销与向下倾斜突出的咬合轮廓40锁定接合。咬合销42可以向内偏斜并且包括凹口,所述咬合轮廓40与所述凹口接合。多个咬合轮廓40和相关的咬合销42分布式地布置在壳体12和覆盖物18的圆周上。
在锁定状态下,当灯具10安装在安装开口中时,密封件16将覆盖物18与侧壁26密封住,从而防止飞溅的水进入壳体12中。例如,密封环为硅酮或另一种弹性体材料。
在安装好的状态下,覆盖物18还将电路板14压到壳体12的底部24,从而提供良好的热接触以将发光二极管48的热量耗散到壳体12中。例如,电路板14包括金属散热结构。确切地说,它是带铝芯的电路板。
除了安装弹簧34和咬合销42以外,覆盖物18还包括透镜单元50,所述透镜单元以截面图在图2中示出。在每个发光二极管48前方,透镜单元50包括透镜元件52。每个透镜元件52中面向LED的末端处具有凹口空隙,例如圆柱形,所述凹口空隙用于将光耦合到正面和圆周面上的环绕透镜元件体中。在外部,透镜元件52形成向前扩张的杯状(chalice-shaped)反射轮廓,该杯状反射轮廓使得在透镜元件52的透明材料中引导的光朝前侧反射。
透镜元件并入透明覆盖物18的前侧覆盖板54中,所述前侧覆盖板基本上为圆盘形。覆盖板54形成透镜单元50以及覆盖物18的自由表面。
覆盖物18与透镜单元50和安装弹簧34以及咬合销42一体形成,例如由PMMA(聚甲基丙烯酸甲酯)或PC(聚碳酸酯)形成。
多个安装弹簧34分布式地布置在覆盖物18的圆周上。各个安装弹簧34从覆盖板54的圆周边缘向外突出,在第一部分56中继续向后延伸,并且从后侧端进一步向外倾斜回到前部。安装弹簧34的截面大约形成V形。其中,第一部分56形成V形的第一支腿(1eg)并且其末端通过短棒连接到覆盖板54。倾斜向外突出的第二部分58形成V形的第二支腿。
在安装好的状态下,安装弹簧34的短棒围绕侧壁26的前侧边缘接合,且第一部分56沿着侧壁26且在侧壁外向容纳轮廓32中的后侧延伸。当安装好的灯具10被插入圆形安装开口中时(图3),安装弹簧34的后侧端支撑在侧壁26外,确切地说是支撑在容纳轮廓32的底部。倾斜地突出到前部的部分58向内偏斜,这样灯具10由安装弹簧34紧固在安装开口60的内圆柱形圆周壁中。
覆盖环20覆盖住前缘,确切地说是壳体12前侧的凸缘部分28,并且可以根据所需设计来成形。覆盖环20可以通过咬合突耳38而咬合锁定在壳体12上,所述咬合突耳围绕覆盖环20中在所述覆盖环20后侧的开口62分布式地布置。这通过以下步骤来实现:将咬合突耳38插入容纳轮廓36中并且向外滑动到容纳轮廓36中的咬合突出物上,同时柔性地偏斜,并且与容纳轮廓36中的咬合突出物64相接合。这在图2中示例性地示出。
在安装好的状态下,覆盖环20以及覆盖物18中一体化的覆盖板54大体位于一个平面内。
图3示意性地示出了嵌入式灯具10的侧视图,其中除了已经描述的组件以外还安装了孔径附接件66,所述孔径附接件以截面图在图4中示出。
孔径附接件66的外部后侧端处包括窄凸缘68,该凸缘从环形壁70向外突出。凸缘68可以在覆盖环20的后侧插入调适的平整的环形空隙72(图2)中,然后再将覆盖环20安装在灯具上。其中,壁70穿过开口62从覆盖环20突出到前部。在该区域中,空隙72可以通过覆盖环20与覆盖板54之间的环形间隙而触及。例如,孔径附接件66形成用于限定嵌入式灯具10的光输出的孔径。孔径附接件66可以根据任何所需设计来成形。
例如,所描述的灯具具有根据58mm安装开口的自由截面的安装直径。嵌入式灯具10的安装深度由凸缘部分28后面的壳体12的深度来决定,它为例如15mm或更小,确切地说,例如13mm。
覆盖环20以及可选的孔径附接件66由例如塑料如聚碳酸酯或ABS(丙烯腈一丁二烯一苯乙烯共聚物)等形成。
所描述的灯具不仅可以不使用工具而是通过几次手动以尤其容易的方式组装并且安装在安装开口60中,其中所使用的电路板14与发光二极管48和插头连接器预先装配在一起。此外,该灯具还可以在不使用工具的情况下从家具中拆卸,因为电连接是经由插头22实现的,而且因为当覆盖环20被拆卸时,安装弹簧34的自由端可以从前部触及,并且可以容易地从安装开口60中脱离。这是因为用于安装弹簧34的容纳轮廓32沿着侧壁26向前延伸到开口端,其中安装弹簧34围绕侧壁36的前缘接合。
此外,在壳体12的后侧处,在咬合轮廓40的区域中,在咬合销42的末端前方设置开口74。因此,位于壳体12内的咬合销,可以从咬合轮廓40脱离,这样覆盖物18可以从壳体12中拆卸。
