Description

LED灯面板
技术领域
本发明涉及一种包括多个发光二极管(LED)的面板。
发明内容
根据第一方面，本发明提供一种在权利要求1中所限定的面板。
从属权利要求限定本发明的优选或可替换的实施例的特征。
本发明的其它方面在其它独立权利要求中被限定。
面板可以是上光面板(glazing panel)和/或照明面板；它可以是支架(shelf)、分隔件(paritition)和墙面覆盖面板(wall coveringpanel)。
面板可以具有至少三个照明电路；它可以具有多于5个或多于10个的照明电路；它可以具有小于50个的照明电路。
每一条母线可以成为与至少三个照明电路的连接。
优选地，仅仅使用两条母线，向面板的所有的照明电路供应电力。这样可以大大地促进面板的电连接。
还可以通过仅具有一个在需要与电源电连接的面板处的位置来促进面板的电连接；这可以在面板的角落处；还可以在沿着面板的一个边缘的某一其它位置处。
所有的母线沿着面板的一个边缘布置的布置可以有助于安装面板和/或隐藏电连接，因为在面板的其它边缘处，连接可能是不必要的。
在支架的情况中，母线可以沿着支架的后边缘或侧边缘布置并被用来支撑支架或将支架安装到墙或其它支撑结构的结构来隐藏。支架的长度可以在0.75m至2.5m的范围内，优选地在0.8m至1.8m的范围内；它们的深度可以在15cm至80cm的范围内，优选地在20cm至50cm的范围内。
在分隔件或墙面覆盖面板的情况中，优选地，母线沿着面板的底边缘布置；通过这样，母线较不明显和/或更容易地隐藏或隐蔽以免被看见，并且/或者更容易连接到外部电源。这种面板的高度可以在0.6m至3.5m的范围内，优选地在1.2m至2.5m的范围内；它们的宽度可以在0.8m至3.2m的范围内，优选地在1.2m至2.4m的范围内。
可以通过直接设置在玻璃基板的一个表面上的导电涂层来设置导电通路。这可以是溅射涂层堆，例如，包含ITO或银的涂层堆，其中，该溅射涂层堆的物理厚度可以在5nm至300nm的范围内。可替换地，它可以是热解涂层(pyrolytic coating)，尤其是通过化学气相沉积所沉积的热解涂层，例如，掺杂有氟或锑的包含锡氧化物的涂层，该热解涂层的厚度可以在100nm至5000nm的范围内。导电涂层的表面电阻(sheet resistance)可以在1至6欧姆/平方(ohms/square)的范围内，或者在2至20欧姆/平方的范围内。
在导电涂层中设置断路(interruption)，以限定一个或多个电通路；可以通过下述方式来设置这种断路：在涂层的沉积过程中进行掩蔽(masking)；或者进行烧蚀(ablation)，例如激光烧蚀、化学蚀刻、磨蚀或切割。直接在一个玻璃基板的一个表面上设置导电通路，尤其以涂层的形式设置导电通路，可以有助于切割成尺寸和/或处理和/或组装。
可替换地，导电通路可以通过与玻璃基板相关联地设置在诸如PET膜的基板上(例如，层叠或粘附到玻璃基板)的导电涂层来设置。在这种情况中，如上所述，涂层可以是溅射涂层。
导电涂层优选地位于基板的基本上整个表面面积之上，例如，位于基板的表面面积的至少90％至95％之上。这可以在面板之上提供基本上恒定的或均质的视觉外观。
(一个或多个)基板可以是玻璃片(glass sheet)；平坦的钠钙玻璃，特别是浮法玻璃，可以用于一个玻璃片，优选地，可以用于两个玻璃片(在使用两片时)。一个或两个玻璃片可以是透明玻璃、超透明玻璃或者本体着色玻璃(body tinted glass)。
尤其在期望用于窗户应用时，上光面板可以是基本上透明的。在这种情况中，该上光面板可以具有大于或等于40％、50％、60％或70％的透光率(CIE Illuminant C(CIE施照体C))和/或小于或等于5％、3％或2％的霾度水平(level of haze)。
尤其在期望用于装修和/或照明目的时，可能不必要的和/或不希望的是：面板是基本上透明的。在这种情况中，该面板可以具有小于或等于20％、10％或5％的透光率(CIE Illuminant C)和/或大于或等于30％、40％或50％的霾度水平。
在一些或所有的LED布置为提供通过导电通路的照明时，使用基本上透明的导电涂层可能是优选的。
第一和第二玻璃片可以通过树脂中间层被层叠在一起，以形成叠层组件，该树脂中间层包括一片或多片PVB或树脂，例如，EVA。塑料中间层可以是基本上透明的；它可以在颜色方面是中性的或透明的，或者，它可以是本体着色的。
优选地，面板的大部分，更优选地，面板的基本上整个表面面积，设置有LED，也就是说，LED形成间隔式LED的阵列，其中，该阵列覆盖面板的表面面积的大于50％、60％、70％、80％或90％。
面板可以包括至少30、50、100或200个LED。
(一个或多个)基板，尤其在呈玻璃片的形式时，优选地具有在2.5mm至10mm的范围内的厚度。
在面板是上光面板时，它可以具有如欧洲标准EN12600(通常称为摆锤式测试)中所定义的机械阻力，该机械阻力为3B3，优选地为2B2，更优选地为1B1。
附图说明
将参照附图描述本发明的非限制性的实施例，在附图中：
图1是呈支架形式的面板的示意平面图；
图2是面板的更多细节的示意平面图；
图3是母线的一部分的示意平面图；
图4是母线的一部分的示意横截面图；
图5是可替换的形式的母线的示意平面图。
具体实施方式
面板10包括通过0.76mm厚的PVB片层叠在一起的第一和第二平坦的、透明的3mm厚的钠钙浮法玻璃片。第一玻璃片的内表面设置有基本上颜色中性的CVD涂层堆，该涂层堆包括SiOxCy底涂层(undercoat)和上覆的SnO2:F涂层。涂层的表面电阻为大约15欧姆每平方。通过大约70微米宽的激光烧蚀形成的涂层堆中的断路11限定LED 12的导电通路，其中，用导电粘合剂将所述LED焊接或附着到激光烧蚀11的任一侧。每一个LED直接接触第一玻璃片的涂层。附加的激光烧蚀13在面板的相对边缘之间进行，以将该面板分成各部分14，其中，每一个部分包含由其LED设置的一个照明电路和在导电涂层中设置的通路。每一个独立的照明电路中的LED串联。
在本实施例中，LED适合通过第二玻璃片提供照明，即，既不通过由涂层设置的导电通路，也不受该导电通路的阻碍。
LED以5cm的间隔按规则的格栅布置，使得二极管的阵列基本上覆盖上光面板的整个面积。每一个LED具有大约4mm2的表面面积。
第一和第二母线21，22基本上沿着面板的一个边缘的整个长度延伸，其中，该面板被层叠在两个玻璃片之间。母线在一个角落处从上光面板突出，以便容易与电源连接。如果照明电路适合接收直流供电，则一条母线将连接到电源的正极接线端，并且另一条母线将连接到电源的负极接线端。
每一条母线具有金属铜芯，该金属铜芯可以在100μ厚的量级上；该芯可以被镀有例如锡的另一种金属。镀层可以是2-3μ厚。以沿着母线的长度的间隔，例如kapton的塑料带31覆盖母线的金属芯31的每一个面。塑料带比金属芯宽，所以它们突出超过芯的每一个侧边缘，如图4所示。这样在其中央部分和其边缘部分之间的母线的厚度上形成阶梯。这样可以有助于在面板的片材之间层叠母线，尤其使用pvb将玻璃片层叠在一起。塑料带相互胶结，并且通过粘合剂将塑料带与金属芯胶结，该塑料带的厚度可以是15-30μ，优选地，可以是大约25μ。
沿着母线定位塑料带32限定了交替间隔开的导电部分33和非导电部分34。该导电部分适合在面板的母线和导电涂层之间提供电连接。非导电部分适合防止在面板的母线和导电涂层之间的电连接。第一和第二母线布置为：使得其导电部分相对于彼此偏移(这同样适用于其非导电部分)。以这样的方式，在面板中构成多个U形照明电路，每一个照明电路从一条母线的连接部分延伸到另一条母线的偏移的连接部分。
母线的绝缘部分的尺寸、其定位和激光烧蚀的定位被布置为避免不希望的短路。根据这一思路，第一母线和第二母线的非导电部分的位置可以重叠。
在可替换的实施例中，这两条母线连接在一起，以形成一个组件。这样有助于组装母线和面板。这可以通过下述方式来实现：例如，使用母线一侧上的上覆粘合剂带将两条母线并排地连接在一起，该上覆粘合剂带不应当与导电涂层电接触，或者，如图5所示，在连续的塑料带51上并排地组装这两条母线，该塑料带比这两条母线的组合宽度宽；以及将绝缘部分52设置在母线的另一个侧上，绝缘部分52用于将第一母线相对于第二母线间隔开或偏移。
就本发明的任何方面而言，可以使用除玻璃以外的基板。
