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 和的光线效果的软管灯改良结构。 背景技术
现有的软管灯作为装饰照明灯具， 已经被广泛应用于园林艺术、商业广告及庭院装 饰等场所， 其优点是： 生产时自动化机器挤出成型， 制作成本低； 使用时可以随意弯折 造型， 可以延接及裁剪， 耐冲击， 安全可靠性好， 可由消费者根据需要随意制作装饰图 案； 装饰效果美妙， 变幻无穷。但同时，现有软管灯的缺点也很明显， 就是发光不均匀、 不连续， 没有霓虹灯的发光效果。 究其原因， 由于软管灯灯管中包覆的光源是一颗一颗 点状发光体， 如微型灯泡或 LED, 间隔地纵向分布在灯管中， 这种颗粒状的点光源发出 的光线， 不能达到霓虹灯均匀连续光线的美感。
霓虹灯作为装饰照明灯具， 其优点是不仅光线鲜艳夺目、色彩缤纷， 而且发光均匀 连续， 美妙柔和， 因此被广泛应用于门面、 招牌、 字幕广告、 舞厅、 酒店酒吧及建筑外 墙等场所。 但是， 霓虹灯也有其致命的弱点， 就是耗电量大、 电压高、 成本高、 玻璃灯 管易碎、 安装运输不方便， 不能随意弯折造型， 不能裁剪， 而且安装维修需要专业的技 术人员， 不便维护， 也极不安全。 所以， 多年来人们一直都在寻找着一种能够代替霓虹 灯的光源。
例如， 人们发明了一种采用压克力材料做外壳的模拟霓虹灯， 如专利号 US.pat.6592238所提供的一种产品， 这种模拟霓虹灯在加热时可以弯折造型， 这是一次 进步， 而且， 此模拟霓虹灯光线均匀、 进续， 可以达到霓虹灯的发光效果。 但是， 由于 压克力材料硬而且脆，所以该模拟霓虹灯在常温下仍然不能随意弯折造型，也不便裁剪； 而且由于其采用灌注胶方式来固定柔性带状电路板和 LED,使得工艺繁琐、制作难度大、 成本高； 另外， 由于柔性带状电路板不可延接， 所以其长度受到限制， 不可延接； 还有， 其采用灌注胶方式也不环保。 因此， 装饰照明市场仍然期望有一种耗电量低、 安全低电 压， 结构和工艺简单、 成本较低， 运输、 安装、 维修都很方便， 可以自由弯折造型， 可 以很方便地根据需要进行裁剪和延接， 且光线均匀连续、 鲜艳柔和的发光装置。 现有的软管灯通常包括如下几个部分， 参见图 16， 长条形透明的塑料内芯 110， 纵 向设置有至少 2根导电线 120、 130,所述的透明的塑料内芯中设置有纵向槽 140或多个横 向孔 150a 150b 150c, 150d、 150e的空间， 用来容置多个灯泡 160a、 160b, 160c, 及其 连接扭结 170a、 170b。 所述的灯泡串联后与所述的导电线作电气连接， 然后再在所述的 透明的塑料内芯上包覆一层透明的塑料包覆层 180。 这种软管灯发出的光线， 不能达到 霓虹灯均匀连续的光线效果， 而且， 这种软管灯由于其导电线 120、 130是水平间隔地设 置在芯线 110内， 所以此软管灯在安装平面内不能随意弯折造型。
又如 1999年 7月 27日授权的美国专利 US.Pat.5927845，该专利揭示了一种采用柔性电 路板作电气连接部件来制作线灯（Linear Light) 的发明。这种线灯是将 LED和电子元件 附设于柔性电路板上， 再在电路板外用两块塑料通过热熔合将电路板包覆而成。该专利 技术的光源是一颗一颗点状发光体，这种颗粒状的点光源发出的光线， 不能达到霓虹灯 均匀连续光线的美感， 而且， 其柔性电路板是水平设置于灯体内的， 这使得其在安装平 面内同样不能随意弯折造型。
因此，一种能够真正具有霓虹灯的均匀连续和鲜艳柔和的光线效果的、而且可以自 由弯折造型、可以很方便地根据需要进行裁剪和延接的软管灯结构， 是软管灯行业长期 以来渴望而且追求的目标。 发明内容
为达到上述目的， 本实用新型一种软管灯改良结构包括：
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一侧壁内， 延纵向上下 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， 该条状体横截 面的另外任意一侧壁沿中线纵向切幵， 形成一个开口槽；
多条柔性带状电路板， 该电路板的同一侧平行于电路板向上设置有若干 LED, 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灯泡上方与上述条状体等长度的， 用于扩散 LED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灯泡的、 与上述条状体等长度的包覆层，该包覆层的位于 LED灯泡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
1 散光体为一整体。
本实用新型所述的柔性带状电路板上附设有恒流 IC;所述的 LED可以为设置有两个 晶片的可双向导通的防静电 LED; 所述 LED可以为 R-G-B三基色 LED。
本实用新型一种软管灯改良结构所述的矩形条状体为透明体或者不透明但透光体。 另外， 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灯泡的侧光的 不透光罩壳。本实用新型所述的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；该不透光罩壳还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； 所述 的不透光塑料层的底部两侧可以设置有便于安装固定的唇边。
本实用新型一种软管好改良结构还可以设置一个注塑成型在电源供电线上的 LED 驱动元件， 该 LED驱动元件是交流变直流的电流转换元件， 也可以是 LED脉冲电流驱动 元件。
本实用新型一种软管灯改良结构所述的散光体， 可以是乳色 PVC不透明但透光体， 而且还可以在该散光体中设置一个纵向通孔。
本实用新型一种软管灯改良结构的另一种实施方案，即所述的矩形条状体为由白色 或者其它颜色的塑料挤出成型的不透光体， 而且还可以在其上方设置一个 槽， 该凹槽 的底部即上述矩形条状体的上部的侧壁沿中线纵向切开， 附设于柔性带状电路板上的 LED设置于该凹槽内， 柔性带状电路板设置了上述矩形条状体内的矩形通孔中。本实施 方案所述的凹槽内可以设置有反光膜。
本实用新型一种软管灯改良结构与现有技术相比其有益效果有： 由于在 LED灯泡照 射上方设置有散光体， 可以使光线连续均匀化， 所以可以模拟霓虹灯的均匀连续的光线 效果，达到了软管灯行业长期以来渴望而追求的目标； 由于采用多条柔性带状电路板并 联接入铜绞合线中的电连接方式， 所以可以裁剪和延接； 同时， 由于柔性带状电路板是 呈立式设置于灯体中， 所以本实用新型在其安装平面内可以随意弯折造型。 附图说明

以下参照附图， 对本实用新型作进一步说明- 参照图 1是本实用新型的透视图， 图 2是图 1中 A-A的横截面图， 图 3是图 1透视图中 F 的放大图， 图 4是本实用新型的第一种最佳实施方案的挤出成型示意图。
木实用新型一种软管灯改良结构， 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 （图中不显示） ， 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个矩形的通孔 06。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 是延纵向上下间隔地设置在该条状体 02的根截面的一侧壁内，该铜绞合线纵向延伸与条 状体等长度。 本实用新型延纵向上下间隔地设置有至少 2根钢绞合线， 这里以设置四根 铜绞合线为实施例进行说明。该条状体 02横截面的另外与四根铜绞合线对应的一侧壁沿 中线纵向切开， 形成一个开口槽 07。 与以往不一样的是， 木实用新型一种软管灯改良结 构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 同一侧。
然后，采用多条柔性带状电路板 03， 该电路板 03的同一侧平行于电路扳向上设置有 若干 LED04, 该 LED可以为 R、 G、 B三种颜色的 LED, 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中的铜绞合线电气连接。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 (图中未显示） 。 每条柔性带状电路板 03都从开口槽 07处塞入上述矩形条状体 02内的矩形通孔 06中。
本实用新型所述的柔性带状电路板上可以附设有恒流 IC05，所述的恒流 IC是一种在 电压变化的情况下能够保持电流不变的电子元件， 它串联于电路板的电路中， 电压变化 范围在 5-90V内， 电流恒定为 20mA以下， 通常为 18mA。 通过恒流 IC05， 可以使本实用 新型亮度更高， 且能维持稳定性。本实用新型所述的 LED可以为设置有两个晶片的可双 向导通的防静电型 LED, 该 LED的封装胶体内并接有两个 LED晶片， 一个正接， 一个反 接， 这样可以使滞留的静电荷被消耗掉， 延长 LED的使用寿命。 另外， 本实用新型所述 的 LED可以为 R-G-B三基色 LED, 与电路板上的控制元件连接形成四线三回路， 通过控 制元件实现变色效果。
如图 16所示， 现有技术的打孔型软管灯， 其芯线 110上的横向孔 150a、 150b, 150c, 150d、 150e及 LED160a、 160b. 160c以及 LED引脚线扭结 170a、 170b是设置在铜绞合线 120、 130之间的， 与铜绞合线 120、 130垂直。 如图 1所示， 本实用新型所述的一种软管 灯改良结构一个重要特征， 是其将铜绞合线 01a、 01b、 01c, Old的一侧边， 这样有利于 本实用新型所述的软管灯，在安装底面上沿纵向长度上弯曲时，铜绞合线 01a、 01b、 01c、 Old位于同一个弯曲半径上， 延伸长度相同， 使安装使用时易于弯曲， 如图 19所示， 避 免了现有技术的打孔型软管灯，如图 16所示的，在安装底面（即发光体底面）上弯曲时， 铜绞合线 120、 130分别位于不同的弯曲半径上， 延伸长度不相同， 造成安装弯曲时的难 度， 以及造成铜绞合线 L的电气连接被拉断。
LED灯泡其低能耗， 低热度， 高亮度， 小体积等优良特性， 可以用来缩短 LED灯泡 的间距， 增加软管灯单位长度中 LED灯泡的数量而不会引起软管灯过热， 可以安全地提 高软管灯的亮度， 而且釆用柔性带状电路板作为 LED的固接部件， 使得 LED的间距可以 小至零， 这样， 本实用新型超过玻璃霓虹灯的亮度变得实际可行， 本实用新型一种软管 灯改良结构的最佳实施方案， 其 LED灯泡直径是 3-5MM, 其 LED亮度大约 200Mcd。
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 16成型孔 17， 如图 4所示， 自动连续挤出由柔性塑料 19， 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 08， 也即是所述的包覆层， 同时， 在该包覆层即散光体 08的下面， 还成型一个由柔性 不透光塑料 18成型的用于包覆条状体及遮挡条状体内 LED灯泡 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 14。 该不透光塑料层 14 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 14的底部两侧可以设置有便 于安装固定的唇边 141， 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 08与该不透光塑料层 14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 08的位于 LED灯泡 04照射上方的部份， 也即是在散光体 08上方 的部份， 其外观是一半圆形曲面 10， 用以模拟霓虹灯玻璃管状发光面。 本实用新型所述 的不透光塑料层 44， 使本实用新型一种软管灯发出的光线， 仅仅从散光体 08的半圆形曲 面 10上照射出。 本实用新型所述的挤出成型机 16为设有两个料斗的双色共挤押出成型 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 16的成型孔 17时，该挤出成型的散光体 08必须设置 在矩形条状体 02内部 LED灯泡 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 08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。
本实用新型一种软管灯改良结构所述的散光体 08， 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 LED灯泡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。 本实用新型一种软管灯改良结构的最佳实施方案， 其 LED灯 泡直径是 3-5mm， 其 LED亮度大约 200Mcd， 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 8-10mm， 如图 2所示。 LED 灯泡发出的光线通过散光体 08折射和漫射后， 相邻的 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 20， 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 度， 如图 5所示。 由此， 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 也即散儿体 08的半圆形曲面 10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 08和不透光罩壳 14成型后， 铜绞合线 01a、 01b、 01c, Old应 当与电源的供电线 11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， 即本实用新型所述的接头 12， 如图 1所示。 另外， 在上述矩形条状体 02 和散光体 08及不透光罩壳 14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， 即本实用新型所述的尾塞 13， 如图 1所示。 电气连接及保护电气连接的 塑料罩壳， 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。
为了提高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 11上的 LED驱动元件 15， 如图 1所示， 该 LED驱动元件 15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。 现有技术的交流变直流， 通常是用 4个二极管整流， 或其他更精密的整流技术， 在此不 做详细叙述。 本实用新型的所述的 LED驱动元件， 也可以是 LED脉冲电流驱动元件， 用 脉冲电流给 LED灯泡供电， 使 LED灯泡发光效率提高， 能耗减少， 也就是说， 在能耗相 同热耗相同时， LED灯泡可以光照亮度要高， 可以进一步提高模拟霓虹灯的光照强度。
本实用新型一种软管灯改良结构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 21与不透光塑料层 14上下对应同时一体挤出成型时，其散光体 21中可以成型一个纵向通 孔 211， 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 211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 08， 因此， 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 方的包覆后即散光体 21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 08的高度 H， 且视纵向通孔 211尺寸的大小不同， HI具体的尺寸也不同， 在此不做详细叙述。
本实用新型一种软管灯改良结构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 081外再通过挤出成型包覆的不透光塑料层 22。该包覆层 081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 10， 其下部份则有一薄层 09包覆于本实用新型所述的矩 形条状体 02外。该包覆层 081所釆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 081押出成型后，再在包覆层 081外通过挤出成型机 23的成型孔 24包覆一不透光 塑料层 22， 如图 12所示。 该不透光塑料层 22包覆于包覆层 081下部份薄层 09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 LED灯泡 04的侧光及底光。该不透光塑 料层 22所采用的原材料 18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。
如图 13， 本实用新型的第三种最佳实施方案的透视图， 图 14是图 13透视图中 E-E的 横截面图， 图 15是图 13透视图中 G的放大图。在这种实施方案中， 所述的矩形条状体 021 为由白色或者其它颜色的塑料挤出成型的不透光体，而且还可以在其上方设置一个凹槽 071， 该凹槽 071的底部即上述矩形条状体 021的上部的侧壁沿中线纵向切开， 形成一个 纵向幵口槽 072， 附设于柔性带状电路板 03上的 LED 04设置于该凹槽 071内，每条柔性带 状电路板 03都从开口槽 072处塞入上述矩形条状体 021内的矩形通孔 06中， 幵口槽 072将 LED灯泡 04的引脚及柔性带状电路板 03夹紧。 在本实施方案中， 为了使软管灯的外观光 照亮度更高， 可以在所述的凹槽 071内设置一层反光膜， 用以将 LED灯泡 04发出的光线 向下的部份全部反射到散光体 08的半圆形曲面 10上， 达到更亮的目的。 因为本实施方案 中矩形条状体 021为由不透光塑料挤出成型的， 所以在上述包覆层上不必再纵向设置用 于遮挡 LED灯泡侧光的不透光罩壳了。 本实施方案中由于 LED灯泡 04的顶部直接与散光 体 08的下面接触，所以散光体 08的高度尺寸 H2应该略小于第一种最佳实施方案的散光体 08的高度尺寸 H， 其具体的尺寸视 LED灯泡 04的间距不同， 在此不做详细叙述。
图 17是本实用新型的现有技术模拟霓虹灯的示意图。这种模拟霓虹灯是先采用压克 力材料注塑成型一杆状体 220， 再采用两块夹板 210与杆状体 220结合形成一柱状空间 250, 然后将附设有 LED灯泡 240的柔性电路板 230置于该柱状空间 250内， 并将 LED灯泡 240的顶部朝向杆状体 220， 最后， 在柱状空间 250内灌注胶水， 以固定柔性电路板 230和 LFD灯泡 240的位置， 并达到电气绝缘和密封的作用。 由于压克力材料硬而且脆， 不可 以弯折， 而且 ¾用灌注胶方式不环保， 所以这种模拟霓虹灯仍有许多缺陷和不足。
图 8是本实用新型的现有技术线灯的结构示意图。这种线灯是将 LED灯泡 340和电子 元件等附设于柔性电路板 330上，再在电路板 330外用两块塑料 310和 320通过热熔合将电 路板 330包覆而成。 该专利技术的光源不能达到霓虹灯均匀连续光线的美感， 而且， 其 柔性电路板 330水平设置于灯体内， 这使得其在安装平面内不能随意弯折造型。
如图 19， 是本实用新型一种软管灯改良结构， 用于制作的模拟霓虹灯的招牌字 "OPEN"， 安装时，将本实用新型的一种软管灯裁剪成所需要的字型图案如 "OPEN"， 并用适当的固定附件如固定夹 25， 将各段字型图案的灯体固定在安装面 26上。 因此， 本 实用新型一种软管灯改良结构安装简单， 安全可靠。 同时， 从本实用新型一种软管灯改 良结构的半圆形曲面 10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 14所遮挡， 使本实用新型一种软管灯改良结构制作的字型图案， 有模拟霓虹灯的光线 效果， 达到了软管灯行业长期以来渴望而且追求的目标， 同时也实现了连续自动化大批 量生产模拟霓虹灯， 从而比许多其他结构的模拟霓虹灯生产批量大， 制作成本低， 具有 其他结构的模拟霓虹灯与软管灯不可比拟的优越性。
