Description

一种软管灯改良结构
本发明所属技术领域
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 柔和的光线效果的软管灯改良结构。
在本发明之前的现有技术
现有的软管灯作为装饰照明灯具， 己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，有人曾用软管灯来模拟霓虹灯，创造了一种"塑料霓虹灯"（或称之为"柔 性霓虹灯")。 虽然这种软管内置 LED作为点光源的装置， 避免了霓虹灯耗电量大、 电压高、 易碎难安装维修的缺点， 而且也可以自由弯折造型， 可以裁剪及延接， 但是 由于其 LED间距较大及外皮厚度均匀且较薄而且采用透明材质， LED颗粒点光源之 间不连续， 外观效果光线呈间断的颗粒状， 不连续、 不均匀， 所以这种软管灯达不到 霓虹灯的装饰效果。 为了解决光线连续均匀化问题， 人们又在软管灯外加了一半透明 的硬质灯罩， 以雾化 LED 点光源发出的光线， 达到光线均匀、 连续、 柔和的效果， 但是这样做无疑又增加了成本， 而且仍然不能随意弯折造型， 不便裁剪， 运输也不太 方便。
在此基础上，人们发明了一种采用压克力材料做外壳的模拟霓虹灯，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、 连续， 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； 而且由于其采用柔性带状电路板作为电 气连接部件以及釆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 11，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)，及其连接线（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)。
在软管灯行业的现有技术中， 软管灯通常按其光源（如灯泡， LED)的设置方式 可分为两种结构： 软管灯的内芯中设置有纵向槽的空间用来容置多个光源， 光源设置 的方向与灯管纵向长度方向相同， 该种软管灯在行业中称为幵槽型软管灯 -Horizontal type; 软管灯的内芯中设置有横向孔的空间用来容置多个光源， 光源设置的方向与灯 管纵向长度方向垂直， 该种软管灯在行业中称为打孔型软管灯 -Vertical type 。
如 1986年 8月 19日授权的美国专利 U.S.4 607 317，专利名称非霓虹灯（non-neon light), 该专利揭示了一种称为 "非霓虹灯"的发明， 即上述打孔型软管灯的发明， 该 专利技术的软管灯比玻璃霓虹灯有更优越的安全、 包装、 安装、 使用及维修性能。 但 该专利没有揭示软管灯与霓虹灯相比所存在的光源缺陷， 即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。
又如 2001年 2月 13日授权的美国专利 U.S.6 186 645 Bl， 专利名称是柔性的照 明系统及安装方法。 该专利也揭示了在软管灯的内芯的外表面或包覆层的内表面设置 有纵向沟槽状纹理， 即开槽型软管灯的改良结构， 该改良结构可以发散软管灯光源发 出的光线， 达到改善软管灯发光的均匀效果。 但本专利没有宣称该发明可以达到模拟 霓虹灯的均匀连续的光线效果， 实际上， 该发明也不能根本上达到模拟霓虹灯的均匀 连续的光线效果。
再如 2003年 5月 20日授权的美国专利 US 6 565 251 B2， 专利名称管状装饰灯。 该专利揭示软管灯的内芯和包覆层均可设置为不同的形状， 如圆形、 方形、 椭圆形、 凸形、 凹形、 波浪形， 以及内芯和包覆层之间形成一个或多个纵向空间， 用以灌注绝 缘液体， 改善光源光线的折射和反射效果。 所述的纵向孔可以是不同的截面形状， 如 圆形、 三角形、 方形、 椭圆形、 梯形。 该专利揭示的是幵槽型的软管灯的改良结构。 该专利未宣称达到模拟霓虹灯的均匀连续的光线效果。 事实上， 在市场上也未见到该 专利的产品能达到霓虹灯的均匀连续的光线效果。
发明目的
本实用新型提供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。 本发明采用的技术方案

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的截面图， 图 3 是本实用 新型的第一种最佳实施方案的挤出成型示意图。
本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： 通常是 2根铜绞合线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 是柔性 PVC， 成型的一个预制长度的条状体， 该条状体即是本行业所述的芯线 02。
然后， 在该芯线上整个纵向长度上， 用自动冲切机 （图中未显示） 间距均匀地冲 制出多个与该铜绞合线平行的横向通孔 03a,03b，03c，03d，该横向孔是设置在条状体中， 与铜绞合线 01a,01b相对的另一侧， 与该铜绞合线平行。
如图 11所示，现有技术的打孔型软管灯，其横向孔 160a，160b,160c是设置在铜绞 合线 120,130之间， 与铜绞合线垂直。 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是上下间隔地设置在该条状体的横截面 一侧， 横向通孔是设置在条状体中， 与铜绞合线平行的另一侧， 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 12所示， 避免了现有技术 的打孔型软管灯， 如图 11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， 以及造成铜绞合线上的电气连接被拉断。
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， 使其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 200 Mcd, 用于容置 LED灯泡的横向孔的中心间距只有 1/2英寸。
在芯线 02成型后， 可以延纵向在芯线 02的两侧面或者两侧面及底面喷涂深色涂 料层， 用以遮挡 LED灯泡发出的光向芯线侧面、 底面发散。 当然， 也可以不在芯线 上喷涂深色涂料层，直接将 LED灯泡 04a,04b—个个塞入芯线中的横向孔 03a,03c中， LED灯泡与 LED灯泡塞入的横向孔之间留有一个横向孔 03b，03d， 用以塞入 LED灯 泡的串联连接线 05， 或其限流电阻 06, 该 LED灯泡串联灯串的首端的引线 07和末 端的引线 （图中未显示） 与上述芯线中的铜绞合线 01a,01b分别作电气连接 （如图 1 所示）。
在上述 LED灯串塞满整个上述预定长度的芯线后， 该芯线 02与一预制的乳白色 不透明体， 即本实用新型一种软管灯改良结构所述的散光体 08， 穿过挤出成型机 20 成型孔 21， 如图 3所示， 自动连续挤出由柔性塑料 22, 通常是柔性透明 PVC， 成型 一个用于包覆上述芯线 02及散光体 08， 与上述芯线等长度的包覆层 09， 该包覆层 09 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。
在芯线 02与散光体 08穿过挤出成型机 20成型孔 21时， 该预制的散光体 08必 须设置在芯线 02中 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， 接近散光体的中线 B-B。 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， 是乳白色不透明体， 或称为雾 状不透明体， 通常是柔性乳白色 PVC 或亚克力 （Acrylic) 挤出成型； 其宽度和高度 是与芯线中 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 200 Mcd, 其 LED发光角度 45QC， 用 于容置 LED灯泡的横向孔的中心间距只有 1/2英寸。 所述散光体的高度尺寸 H是 14 mm, 散光体的宽度尺寸 L是 8mm， 透明 PVC层 11厚度尺寸 S1是 2 mm， 透明 PVC 层 12厚度尺寸 S2 是 2mm， 如图 2， 图 3所示。 LED灯泡发出的光线两次通过透明 PVC层 11， 12 折射后， 和通过所述的散光体 08漫射后， 相邻的 LED灯泡发出的光 线的边缘区域相互重叠， 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 4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 09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。
在上述包覆层成型后， 铜绞合线 Ola, 01b应当与电源的供电线 13， 做电气连接， 以及在该电气连接上， 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 14， 如图 1 所示； 以及在上述芯线 02及包覆层 09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 15， 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， 已有许多中不同的实施 方法， 在此不做详细叙述。
本实用新型一种软管灯改良结构， 为了加强模拟霓虹灯的玻璃管状发光效果， 有 必要使本实用新型一种软管灯发出的光线， 仅仅从包覆层的半圆形曲面 10上照射出， 因此， 可以包括一纵向设置在上述包覆层 09上、 用于遮挡 LED灯泡的侧光的不透光 罩壳， 也就是说， 用一不透光罩遮挡除半圆形曲面外的包覆层的其它部分， 如两侧光 面和底面， 但是至少要遮挡 LED灯泡的两侧光面。 该不透光罩壳 16可以是与所述的 包覆层一体挤出成型的不透光的塑料层， 如图 1， 图 2所示； 该不透光罩壳的另一最 佳的实施方案， 可以是一纵向镶嵌在上述包覆层上的不透光的轨道 18， 如黑色塑料轨 道或涂有黑色油漆的金属铝轨道， 如图 5， 图 6所示； 该不透光罩壳还可以是纵向喷 涂于上述包覆层两侧面或者两侧面及底面的深色涂料层。 值得一提的是， 如果如前面 所述延纵向在芯线 02 的两侧面或者两侧面及底面喷涂了深色涂料层， 那么就可以不 必再在包覆层 09上设置该不透光罩壳了。
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 电线上的 LED驱动元件 17， 如图 1所示， 该 LED驱动元件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， 消除 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灯泡可以光照亮度更高， 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， 第二种最佳实施方案是： 如图 5， 图 6所示， 在上述 LED灯串塞满整个上述预定长度的芯线 02后，不需要预先独立制作散光体 08， 在上述芯线 02穿过挤出成型机成型孔时， 所述的散光体 08， 即乳色不透明体与包覆 层 09同时自动连续挤出成型， 在芯线 02上方的形成包覆层 19， 该芯线 02上方的包 覆层 19 的高度尺寸 H2略小于在第一种最佳实施方案中散光体的高度尺寸 H、 透明 PVC层 11厚度尺寸 Sl、 透明 PVC层 12厚度尺寸 S2 之和， 是 16 mm, 包覆层 19 其宽度是 8 mm。 此时， 上述包覆层 09的自动连续挤出成型用的柔性塑料， 通常是柔 性乳白色不透明 PVC塑料。
上述第二种最佳实施方案的结构， 可以做有另外一种结构方案， 即可以是所述的 散光体 08， 在与包覆层 09同时自动连续挤出成型时， 由散光体 08和包覆层 09构成 的， 在芯线 02上方形成包覆层 19， 在该芯线 02上方的包覆层 19中设置一个纵向通 孔 20， 用以节省材料， 如图 7， 图 8所示。 此时， 由于该纵向通孔 20中空气对光线 的折射和发散能力， 不及乳白色不透明 PVC材质的散光体， 因此， 为了达到霓虹灯 同样的连续均匀光线效果， 如图 7, 图 8所示的在芯线 02上方的包覆层 19的髙度尺 寸 H3应当大于， 如图 5, 图 6所示的第二种最佳实施方案中所述的在芯线 02上方的 包覆层 19的高度 H2, 视纵向通孔 20尺寸的大小不同， 具体的尺寸， 在此不做详细 叙述。
上述第一种最佳实施方案的结构中可以有另外一种结构方案， 即不需要预先独立 制作散光体 08， 如图 9， 图 10， 在自动挤出成型芯线 02时， 与芯线等长度一体挤出 成型的乳色不透明体。 此时， 上述芯线和散光体的自动连续挤出成型用的柔性塑料， 通常是柔性乳白色不透明 PVC塑料。 此实施方案相应影响的是芯线 02上横向孔， 在 整个纵向长度上， 必须要用钻空机间距均匀地钻制出多个与该铜绞合线平行的横向盲 孔 03。
如图 12， 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 30， 将各段字型图案的灯体固定在安装面 31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 16或者芯线上的深色涂料层所遮挡， 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。
