Description
[技术领域]
本发明涉及LED灯封装技术领域，具体的说是一种线条型LED及其生产方法和应用。
[背景技术]
线条型LED，纤细轻巧，宽度3～4毫米，厚度1～2毫米，发光间距最小3～4毫米，并可象及时帖一样粘帖在所需之处，非常方便；而且柔软性很好，三维空间可任意折弯；线条型可任意截断，按需取用；也可任意连接，对使用效果没有运任何影响。
国内专利CN101403478A公开了一种无缝连接LED线条灯的结构，该结构由若干个LED封装单元和PCB线路版组成：
其无法在灯条平面方向弯转，不能任意弯折，也就无法组成字体，和特殊照明
其线路板组成形式无法任意裁断和连接，一定要按线路板的分开点才能不损坏线路板二裁断和连接；
其线路板组成无法做到LED间距小，条形体积小，因此就无法做成小的发光字，更不用说Logo、图案，或特殊照明了。
[发明内容]
本发明的目的是对现有技术和封装结构进行改进，提供一种密封性更好，能用于特殊极小安装位置，可弯曲、可用于室内外的更实用的线条型LED结构和封装方法。
为实现上述目的设计一种线条型LED，包括LED灯和电源，其特征在于线条型LED为近似长方形，金属条b和金属条c之间设有内置电阻和LED芯片的安放块，上部金属条a至金属条b间设连接块，下部金属条c至金属条d间设连接块，金属条a与金属条b的间距与金属条c与金属条d间距相等，金属条b和金属条c内折90度，所述安放块左右设有压痕线e、f，在压痕线e和f的外设有金属长方块g和h，金属长方块g和h沿压痕线内折90度，形成LED封装碗，在封装碗的框架上设有内置电阻并用金线串联LED芯片，碗内封装有环氧树脂，环氧树脂层断开两边金属，使内边金属不导通，并在碗的框架上引出电源接线。
线条型LED的正面或反面或两侧设有透明的不干胶。
线条型LED封装碗的LED宽度为3～5mm，发光间距4～12mm，电流20mA～1A，电压为3～24伏。
线条型LED的封装中设内置电阻。
本发明还包括一种线条型LED的生产方法，其特征在于该方法如下：
a)设计线条帖框架结构形状，设置折痕线，设置内置电阻、LED芯片安放处的形状结构，框架结构采用金属材料组成，
b)金属条b、金属条c折起90度，
c)内置电阻及LED芯片的安放处的金属长方块g和金属长方块h沿压痕线折起90度，形成一个LED封装碗的结构，
d)在碗内框架连接内置电阻后用金线串联LED芯片，并在碗内封装环氧树脂，
e)在每个电流允许值长度的一半处，引出电源接线，以保证LED用电正常安全，
f)在所需面放透明不干胶，并和封装好的LED一起在模具内用硅胶密封。
本发明是一种创新产品，绿色环保，可作为霓虹灯、LED模组，及时帖等材料的升级替代。它使用简便，省工省时，广告效果好，运用面广泛：粘帖在门、窗玻璃上或写真喷绘上，可作为发光的门面、门牌字或舞台背景的发光字体、图案、logo等；可用于宾馆，商场等公共场合的指示，标识；可用于特殊灯箱的背光照明（如超薄2～3公分厚的灯箱，卷携式灯箱等）；可用在水晶吊灯、各种艺术灯具、室内装潢照明；可用在特定发光字上（如细笔划发光字、图案、logo或小形的发光字等）；更可用于特殊的或极小安装位置的光照及各种特定要求的照明,本产品密封性好，可用于室内，也可用于室外，可弯成各种文字、图案或logo用于装饰、广告，也可作为光源，用于灯箱、发光字、灯具及各种照明灯具。
[附图说明]
图1是本发明的框架展开图；
图2是本发明的框架结构图；
图3是本发明的安装示意图；
图中：a、b、c、d均为金属条e、f均为压痕线g、h为金属长方块。
[具体实施方式]
结合附图对本发明做进一步说明，这种装置的制造技术对本专业的人来说是非常清楚的。
线条型LED采用一种新的封装形式，即以框架连接成单向连续的条形封装。因而生产出的LED形状也是新的形式；连续的条形（目前所有的封装形式，只有单个LED和组块的LED两种形式），为实现这种形式的封装，必须运用新的框架结构和封装工艺：
1.框架的展开（如图1所示）：线条型LED为近似长方形，金属条b和金属条c之间设有内置电阻和LED芯片的安放块，上部金属条a至金属条b间设连接块，下部金属条c至金属条d间设连接块，金属条a与金属条b的间距与金属条c与金属条d间距相等，所述安放块左右设有压痕线e、f，在压痕线e和f的外设有金属长方块g和h。内置电阻、LED芯片安放处的形状结构根据不同型号需要单独设计而定，在此仅作位置示意。
2.如图2所示，金属条b和金属条c内折90度，内置电阻及LED芯片安放处的两旁金属长方块g和h沿压痕线内折90度，形成一个LED封装“碗”。
3.如图3所示，在“碗”内框架联接内置电阻（阻值按各型号LED计算而定）后用金线串联LED芯片，并在“碗”内封装环氧树脂。固化后去掉一小块，使二边断开不导通。
4.在每个电流允许值长度的一半处，引出电源接线，以保证LED用电正常和安全。
5.在所需面放透明不干胶（因为有的帖在玻璃上，需要正面粘贴，透过玻璃发光。而有的直接粘在所需处，则需要反面粘帖正面直接发光），并和封装好的LED一起在模具内用硅胶密封。
由此就形成了新的封装形式（单向连续条形封装），生产出新的LED形状（连续条形，柔软易折，精小纤细，任意截接，粘帖方便）运用在许多新的领域，也可制造出更多新型产品。
实施例1：
如宾馆、商场或一般门面、商店的玻璃门玻璃墙上警示贴条，现在都用及时贴。而改用本产品则更加美观，警示效果更强，而且做成logo或其他广告文字图案，同时还产生视觉冲击力很强的广告效果。
这一用途产品基本远视，所以线条要细、发光间距一般、功率不大但要艳亮，因此采用宽度3mm，发光间距6mm,电流20mA,功率0.06w的红色LED。
框架结构如图2所示。使用比较常用的5v电压，所以内置电阻100欧，与LED芯片串联。封装环氧树脂后切断二边，正面上不干胶（粘在玻璃上，发光可透过玻璃）。然后用硅胶密封。
LED所需电流仅20mA，所以一般来说就只要在其端部焊上电源引线，接上5v直流电源即可。只有在单闩玻璃门宽超过1.5米，或玻璃墙宽度大于3米的情况下才需要在1.5米处引出一组电源引线（为了美观，电源引线粘贴在LED背后延伸到端部）。
此产品的不干胶上在反面，就可以用在喷绘或写真上。如会务、展览等大型的喷绘布上粘帖后就在其上面形成发光字或图案；在原来喷绘或及时贴店名牌上粘贴后就形成发光字店牌，不仅方便美观还比做亚克力的发光字便宜得多。
实施:2：
再以上例为基础，LED改用白色（或其他颜色、型号），间距缩小到3～4mm，可用在水晶吊灯上：将之粘贴在水晶吊灯的水晶件上（如水晶球上半球上粘一小圈），电源引线用漆包线并再涂上金属吊架相同的颜色（如金色、银色）。由此制成的水晶吊灯光线是透过水晶射出来的，每个水晶挂件晶莹透亮，光彩夺目，非常漂亮，寿命长，省电环保，免除原来灯泡坏了经常检查调换等繁琐事，还可以根据用户需要制成各种颜色灯光，甚至七彩变幻光（如酒吧、舞厅）的水晶吊灯。
