Description

一种双面发光的LED软管灯
技术领域
本实用新型涉及一种装饰灯，尤其涉及一种双面发光的LED软管灯。
背景技术
LED软管灯由于其节能、寿命长、发光均匀柔和、可弯曲性强等优点，颇受人们青睐，目前已被广泛应用于城市夜景装饰、商业招牌、建筑外形装饰等方面。
现有的LED软管灯其结构为：贴片式LED焊接在柔性电路板上组成发光体,再在发光体外围包覆一包覆层。由于现有的LED软管灯都是单面发光，不能做到通体发光，因此应用在空间悬挂或立体图案造型等装饰照明场所时效果不好。
发明内容
为解决上述问题，本实用新型提供了一种光线连续均匀、可以达到通体发光效果、而且结构简单、生产便捷的双面发光的LED软管灯。
为了实现上述目的，本实用新型采用的方案是：
一种双面发光的LED软管灯，包括LED、限流电阻、柔性电路板、金属绞线、包覆层，所述包覆层包覆于LED、限流电阻、柔性电路板和金属绞线的外围，其特征在于：所述的柔性电路板两面都焊接有LED。
进一步地，所述的柔性电路板两面至少一面焊接有限流电阻。
进一步地，所述的柔性电路板两面的LED形成间隔错开或对齐分布。
进一步地，所述的金属绞线与柔性电路板电连接，且沿柔性电路板长度方向并排设置。
进一步地，所述的包覆层包括一内包覆层和一外包覆层。
进一步地，所述的金属绞线与内包覆层通过押出技术一体成型。
进一步地，所述的内包覆层为一内部是空腔且贯通其长度方向有一开缝的柔性胶条。
进一步地，所述内包覆层的空腔横截面形状包括圆形、椭圆形、矩形、D形、梯形。
进一步地，所述外包覆层的横截面形状包括圆形、椭圆形、矩形、D形、梯形。
进一步地，所述的包覆层由包含有混光物质的透明或透光的柔性材料制成。
本实用新型具有如下的有益效果：本实用新型通过在一块柔性电路板的两面都焊接上LED，有效地增大了灯体的发光角度，再加上内、外包覆层内部的散光物质或光线在灯体内部的折射作用，使灯体可以达到360度发光的效果，可以应用于空间悬挂或立体图案造型等装饰照明场所；另一方面，本实用新型还具有结构简单，生产工艺简单，成本低等优点。
附图说明
图1是本实用新型实施例一已焊接好LED及控流元件的柔性电路板立体图。
图2是本实用新型实施例一的内包覆层示意图。
图3是本实用新型实施例一的立体结构图。
图4是本实用新型实施例二已焊接好LED及限流电阻的柔性电路板立体图。
图5是本实用新型实施例二的立体结构图。
图6是本实用新型不同形状的内包覆层和外包覆层的多种组合示意图。
具体实施方式
实施例1
如图1所示，在柔性电路板的两面以间隔错开的分布方式焊接上LED及控流元件；如图2、图3所示，金属绞线嵌入于内包覆层，通过押出成型技术一体成型，内包覆层为一内部是空腔且贯通其长度方向有一开缝的柔性胶条，在生产过程中，先掰开开缝，然后把焊接好LED及限流电阻的柔性电路板从开缝处侧向塞入内包覆层的空腔内，并调整好柔性电路板位置，再在需要焊接处切开内包覆层一小缝，使金属绞线外露，再用导线把金属绞线与柔性电路板电连接在一起。最后，通过挤出成型技术，在内包覆层外部密封包覆一层外包覆层。
实施例2
如图4所示，在柔性电路板的两面以对齐的分布方式焊接上LED及控流元件；从图5可看出，该实施例的除柔性电路板上的灯珠分布不相同外，其余的结构及生产工艺与实施方式1相同， 在此不再赘述。
作进一步优化，本实用新型的内包覆层和外包覆层为柔性的透明或透光材料制成，包含有混光物质，能使灯体发出更柔和、均匀的光；同时，如图6所示，本实用新型的内包覆层空腔与外包覆具有多种形状，通过对多种形状的组合可以得到多种应用结构。
上述的实施例仅用于说明本实用新型的技术方案，并不构成对本实用新型保护范围的限定，本实用新型的保护范围还包括本技术领域的技术人员在对本实用新型没有做出创造性劳动前提下所做出的各种修改与替换。
