Description

一种新型软管灯
技术领域
本实用新型涉及一种装饰照明装置，尤其是一种能模拟霓虹灯的连续均匀和鲜艳 柔和的光线效果的新型软管灯。 背景技术
现有的能楱拟霓虹灯的连续均匀的光线效果的软管灯，因为其芯线或矩形条状体 内的铜绞合线是呈上下间隔设置的，所以可以在安装平面内随意弯折造型，如申请号 为 200420093781.5所提供的产品， 其矩形条状体内的铜绞合线就是呈上下间隔设置 的， 这样可以在安装平面内随意弯折造型， 但是， 也正是因为这种软管灯其铜绞合线 是呈上下间隔设置的，所以这种软管灯就不能在球形体或者凹凸不平的表面上沿着表 面进行安装和弯曲造型， 这不能说不是一个弊端； 而且， 这种软管灯其矩形条状体内 的柔性带状电路板是采用手工焊接 LED灯泡的， 这给生产自动化带来麻烦， 不能实现 连续自动作业。
另外， 现有的能模拟霓虹灯的连续均匀的光线效果的软管灯， 如申请号 200320130244.9所提供的产品， 其芯线内的 LED灯泡要通过手工连线、 焊接及插入芯 线内的横向孔中， 这些作业机械化程度都不很高， 不利于自动化批量生产。 即使是如 专利号 0211719.7所述的可挠性发光体装置及其制造方法所揭示的一种产品， 其釆用 C.O.B.式 （Chip On Board) LED作为光源， 但其所用的电路板为一小块一小块的， 每 一小块电路板上只设有一个 C.O.B.式 LED晶元， 通过对每一小块电路板进行连接来实 现 LED晶元之间的电气连接， 这样， 其自动化程度显然不高； 而且， 该专利提供的产 品不能达到霓虹灯连续均勾的光线效果。
因此，一种能模拟霓虹灯的连续均匀和鲜艳柔和的光线效果的、 自动化生产程度 高的、可以在球形体或者凹凸不平的表面上沿着表面进行安装和弯曲造型的软管灯成 为市场需求。 发明内容
本实用新型的目的是为了解决上述提出的问题，提供一种可以在球形体或者凹凸 不平的表面上沿着表面进行安装和弯曲造型的、 自动化生产程度高的、能模拟霓虹灯 的连续均匀的光线效果的软管灯。
为达到上述目的， 本实用新型釆用的技术方案是一种新型软管灯， 包括： 一矩形条状体， 由柔性塑料挤出成型一个预定长度的横截面为矩形的条状体，该 条状体延纵向在其内部设置有一矩形的通孔，该条状体的横截面的下侧壁内，延纵向 间隔地设置有至少 2根铜绞合线， 该铜绞合线纵向延伸与条状体等长度， 并且， 该条 状体横截面的下侧壁沿中线纵向切开， 形成一个开口槽； ， 多条柔性带状电路板， 该电路板的同一面上设置有至少一列 LED发光体，每条电 路板的两端部都焊接有导电引脚线，且导电引脚线与上述条状体中的铜绞合线电气连 接， 所述柔性带状电路板设置于上述条状体内的矩形通孔中；
一散光体， 设置在上述 LED发光体上方与上述条状体等长度的，用于扩散 LED发 光体光线的预定高度和预定宽度的乳色不透明但透光体；
一包覆层， 由柔性塑料挤出成型一个用于包覆上述条状体、散光体及 LED发光体 的、与上述条状体等长度的包覆层，该包覆层的位于 LED照射上方的部份是一模拟霓 虹灯玻璃管状发光面的半圆形曲面， 该包覆层与上述散光体是等长度一体挤出成型 的， 与散光体为一整体。
本实用新型所述的矩形条状体为透明体或者不透明但透光体。
本实用新型所述的 LED发光体可以为表面粘著型 LED;还可以为封装胶体设置成 扁形立方体的普通 LED。
本实用新型还可以包括一纵向设置在上述包覆层上、用于遮挡 LED发光体的侧光 的不透光罩壳。该不透光罩壳可以是与所述的包覆层上下对应同时一体挤出成型的不 透光塑料层；也可以是在所述的包覆层外再通过挤出成型包覆的不透光塑料层。所述 的不透光塑料层可以是具有反光作用的白色不透光塑料层；该不透光塑料层的底部两 侧可以设置有便于安装固定的裙边。
本实用新型所述的散光体， 可以是乳色 PVC不透明但透光体； 可以在该散光体 中设置一个纵向通孔。
本实用新型一种新型软管灯与现有技术相比其有益效果有：由于矩形条状体中的 铜绞合线是呈水平并排设置在其横截面的下侧壁内，这样，软管灯可以在上下方向上 随意弯折，所以本实用新型可以在球形体或者凹凸不平的表面上沿着表面进行安装和 弯曲造型， 由于在柔性带状电路板上设置焊接表面粘著型 LED,可以由机器代替人工 作业， 即釆用现有的 SMT插片技术，进行连续自动化生产，所以本实用新型自动化生 产程度高， 可以实现大批量连续自动化生产软管灯。 附图说明

本实用新型一种新型软管灯，第一种最佳实施方案其制作过程包括： 采用四根铜 绞合线 01a、 01b、 01c、 Old穿过挤出成型机成型孔 （图中未显示） ， 自动连续挤出由 柔性塑料， 通常是透明或者不透明但透光柔性 PVC， 成型的一个预制长度的横截面为 矩形的条状体 02， 该矩形条状体延纵向在其内部设置有一矩形的通孔 05。该矩形条状 体 02为透明体或者不透明但透光体。 该条状体 02中的四根铜绞合线 01a、 01b、 01c、 Old是延纵向间隔地设置在该条状体 02的横截面的下侧壁内， 该铜绞合线纵向延伸与 条状体等长度。 本实用新型延纵向间隔地设置有至少 2根铜绞合线， 这里以设置四根 铜绞合线为实施例进行说明。该条状体 02横截面的下侧壁沿中线纵向切开， 形成一个 开口槽 06。与以往不一样的是， 本实用新型一种新型软管灯所述的矩形条状体其铜绞 合线 01a、 01b, 01c、 Old是位于矩形条状体 02的横截面的下侧壁内。
然后， 采用多条柔性带状电路板 03， 该电路板 03的同一面上设置有至少一列 LED 发光体， 该 LED发光体可以为表面粘著型 LED (即 SMD LED, 英文名 surface mount device LED) ， 可以为封装胶体设置成扁形立方体的普通 LED, 其发光颜色可以为 R、 G、 B三种颜色。本实施例中电路板 03上设置有三列表面粘著型 LED,如图 3中 04所指。 每条电路板的两端部都焊接有导电引脚线，且导电引脚线与上述条状体 02中的铜绞合 线电气进接。如柔性带状电路板 03的一端焊接有三条导电引脚线， 这三条导电引脚线 分别接入铜绞合线 01a、 01b、 01c, 电路板 03另一端的导电引脚线则接入铜绞合线 Old 中 （图中未显示） 。 每条柔性带状电路板 03都从开口槽 06处塞入上述矩形条状体 02 内的矩形通孔 05中。 值得一提的是， 本实施例采用柔性带状电路板安装表面粘著型 LED可以采用现有的 SMT插片技术，这样可以实现机械自动化生产，大大提高了生产 率。
如图 13所示， 现有技术的软管灯 （申请号 200320130244.9) ， 是采用芯线 120外 包散光体 180和遮光层 190制成的，其将铜绞合线 110a、 110b上下间隔地设置在芯线 120 的横截面的一侧， 而 LED140a， 140b则是设置在与铜绞合线 110a、 110b相对的另一侧 边，这样使得该软管灯在安装底面上只能在中面上弯曲造型，而不能沿着凹凸不平的 底面安装和弯曲造型。 另外， 由于其 LED140a， 140b及 LED之间的连接线扭脚 150以 及限流电阻 160要通过手工连接，并且需要手工将其塞入芯线 120的横向孔 130a、 130b, 130c、 130d内， 再将该 LED灯串通过导线 170与铜绞合线 110a、 110b连接， 这样其自 动化作业程度不高， 影响生产率。
如图 14， 本实用新型的现有技术采用 C.O.B.式 LED制作软管灯的示意图， 该技术 是将 LED晶片 220直接安装在一小块电路板 210上，然后将装有 LED晶片的小块电路板 通过导线 240连接成串， 并在小块电路板之间连接电阻 230， 这样形成 LED晶片灯串， 再将该 LED晶片灯串的首尾两端接入主导线 250、 260中， 并将 LED晶片灯串设置于固 定凹槽 270内，最后通过押出成型在 LED晶片灯串和固定凹槽 270外包覆一透光的薄层 280, 这样制成该软管灯。 在该项技术中自动化程度显然不高。
在上述柔性带状电路板及 LED塞满整个上述预定长度的矩形条状体后，该条状体 02穿过挤出成型机 15成型孔 16， 如图 4所示， 自动连续挤出由 性塑料 18， 通常是柔 性的乳色不透明但透光 PVC，成型一个用于覆盖上述条状体 02的与上述条状体等长度 的散光体 07， 也即是所述的包覆层， 同时， 在该包覆层即散光体 07的下面， 还成型一 个由柔性不透光塑料 17成型的用于包覆条状体及遮挡条状体内表面粘著型 LED 04的 侧光和底光的不透光罩壳， 也即是将条状体 02的两侧面及底面包覆的不透光塑料层 13。该不透光塑料层 13可以是具有反光作用的白色不透光塑料层。该不透光塑料层 13 的底部两侧可以设置有便于安装固定的裙边 131， 如图 6、 图 7所示， 即第一种最佳实 施方案的第二种结构方案。所述包覆层即散光体 07与该不透光塑料层 13是上下对应同 时一体挤出成型的， 两者为一整体。 该包覆层即散光体 07的位于表面粘著型 LED 04 照射上方的部份， 也即是在散光体 07上方的部份， 其外观是一半圆形曲面 09， 用以模 拟霓虹灯玻璃窗状发光面。本实用新型所述的不透光塑料层 13，使本实用新型一种软 管灯发出的光线，仅仅从散光体 07的半圆形曲面 09上照射出。本实用新型所述的挤出 成型机 15为设有两个料斗的双色共挤推出成型机， 本技术已很普遍， 在此不做叙述。
在矩形条状体 02穿过挤出成型机 15的成型孔 16时，该挤出成型的散光体 07必须设 置在矩形条状体 02内部表面粘著型 LED 04的正上方， 也就是说， LED灯泡 04应当设 置在该散光体的下方， 接近散光体 07的中线。在软管灯工业中要实施上述要求，是普 通的现有技术， 在此不做更多叙述。
本实用新型一种新型软管灯所述的散光体 07， 是乳白色不透明但透光体， 或称为 雾状不透明但透光体， 通常是由柔性乳白色 PVC料挤出成型， 其宽度和高度是与矩形 条状体 02中表面粘著型 LED的亮度和照射角度相关， LED灯泡的亮度高或照射角度 大， 其高度和宽度可以大一点， LED 灯泡的亮度小或照射角度小， 其高度和宽度必 须小一点。 散光体的宽度和高度愈大， 则愈损失本实用新型一种软管灯的外观亮度， 相应消除点状光源的外观效果好； 散光体的宽度和高度愈小， 愈减弱本实用新型一种 软管灯消除点状光源的外观， 相应外观亮度高。本实用新型一种新型软管灯的最佳实 施方案，其 LED亮度大约 22 Mcd，其 LED发光角度 45°C， LED灯泡的中心间距 5-8mm。 所述散光体的高度尺寸 H是 14mm， 其宽度尺寸 L是 24mm， 如图 2所示。 LED灯泡发出 的光线通过散光体 07折射和漫射后， 相邻的表面粘著型 LED灯泡 04a、 04b, 04c, 04d 发出的光线的边缘区域相互重叠， 如 LED灯泡 04b、 04c发出的光线的边缘区域形成重 叠区 19， 使 LED灯泡在边缘区域光照亮度得到加强， 而约等于 LED灯泡中心部位发出 的光照亮， 如图 5所示。 因此， 在本实用新型一种软管灯的 LED灯泡 04的照射上方， 即包覆层也即散光体 07的半圆形曲面 09上，从外观上看，有霓虹灯连续均匀的光线效 果。
在上述包覆层即散光体 07和不透光罩壳 13成型后， 铜绞合线 01a、 01b、 01c、 Old 应当与电源的供电线 10做电气连接， 以及在该电气连接位置上， 设置一塑料罩壳， 用 以保护该电气连接， 即接头 11， 如图 1所示。 另外， 在上述矩形条状体 02和散光体 07 及不透光罩壳 13的末端上，设置一用以包覆该末端的铜绞合线及其电气连接线的塑料 罩壳， 即尾塞 12。 电气连接及保护电气连接的塑嵙罩壳， 在现有技术中， 已有许多种 不同的实施方法， 在此不做详细叙述。
为了提髙模拟霓虹灯的发光效率和光照强度，可以设置一个注塑成型在电源供电 线 10上的 LED驱动元件 14， 如图 1所示。 该 LED驱动元件 14可以是信号控制器， 用以 控制 LED的发光状态， 实现闪烁、 变色、 混色等效果； 也可以是交流变直流的电流转 换元件， 用直流电流给 LED灯泡供电， 使 LED灯泡发光稳定， 避免 LED灯泡发光时闪 烁。
本实用新型一种新型软管灯的第一种最佳实施方案的第三种结构方案，所述的散 光体， 可以在其散光体中设置一个纵向通孔， 如图 8、 图 9所示。 所述包覆层即散光体 20与不透光塑料层 13上下对应同时一体挤出成型时，其散光体 20中可以成型一个纵向 通孔 201 , 这样， 可以节省材料， 从而使本实用新型一种软管灯成本更低。 此时， 由 于该纵向通孔 201中空气对光线的折射和发散能力， 不及乳色不透明 PVC材质的散光 体 07， 同此， 为了达到霓虹灯同样的连续均匀光线效果， 如图 8、 图 9所示的在矩形条 状体 02上方的包覆层即散光体 20的高度尺寸 HI应当大于如图 1、 图 2、 图 6、 图 7所示的 第一种最佳实施方案中所述的在矩形条状体 02上方的包覆层即散光体 07的高度 H， 且 视纵向通孔 201尺寸的大小不同， HI具体的尺寸也不同， 在此不做详细叙述。
本实用新型一种新型软管灯的第二种最佳实施方案如图 10、图 11所示， 图 12是本 实用新型的第二种最佳实施方案的挤出成型示意图。在这种实施方案中.所述的不透 光罩壳是在所述的包覆层 071外再通过挤出成型包覆的不透光塑料层 21。该包覆层 071 是通过押出机在矩形条状体 02外一次性挤出成型的，其上部份即是本实用新型所述的 散光体，其外观同样是一半圆形曲面 09，其下部份则有一薄层 08包覆于本实用新型所 述的矩形条状体 02外。 该包覆层 071所采用的原材料通常是柔性的乳色不透明但透光 的 PVC料。在包覆层 071押出成型后，再在包覆层 071外通过挤出成型机 22的成型孔 23 包覆一不透光塑料层 21， 如图 12所示。 该不透光塑料层 21包覆于包覆层 071下部份薄 层 08的外围， 用来遮挡本实用新型一种软管灯矩形条状体 02内的表面粘著型 LED 04 的侧光及底光。该不透光塑料层 21所采用的原材料 17通常是柔性不透光塑料，也可以 是具有反光作用的白色不透光塑料，这样有利于增加本实用新型一种软管灯的外观亮 度。
本实用新型一种新型软管从其半圆形曲面 09的外观上看，有连续均匀的光线效果， 其余的光线都被不透光罩壳所遮挡， 使本实用新型一种新型软管灯有模拟霓虹灯的光 线效果。 本实用新型可以在球形体或者凹凸不平的表面上沿着表面进行安装和弯曲造 型。 本实用新型自动化生产程度高。
