Description

一种 LED线条灯具 所属技术领域
本发明涉及一种 LED线条灯具， 是对现有 LED灯具以及霓虹灯的增强和改进， 属于 LED 装饰照明领域。
背景技术
随着 LED半导体光源技术的逐步完善和成熟， 以及节能环保低碳概念的普及， LED光源必 将会逐歩取代灯泡、 节能灯、 光灯、 以及广告用的霓虹灯等传统照明及广告光源。
传统的霓虹灯， ώ于制作工艺以及电气原理的限制， 使得传统霓虹灯生产过程繁琐， 成 本昂贵， 现场安装施工过程复杂， 能源消耗高， 用户使用起来要为之付出高额的电费， 而且 灯光线条是由一段一段组成， 缺乏连续性； 故障率高， 使用寿命没有保障。
现有的广告灯箱 （包括广告发光字和发光图案）， 基本都是把光源 （FI光灯或 LED光源） 放置于灯箱内， 灯箱表面用具有相应透光特性并覆以相应色彩和图案的板材覆盖， 致使图案 发光。 这种广告灯箱 ώ于结构所限且光源设置不合理， 致使整体发光强度受限制， 光效浪费 严重， 很难达到理想的广告光效， 从而造成能源浪费。
现在市场上的 LED电子灯箱， ώ于是把 LED直接暴露出来以 LED点阵的形式显示灯光图案， 使得光线十分刺眼， 光斑明显， 光污染严重， 使整体灯光的广告视觉显得档次不高。
市场上的柔性灯带， 每颗 LED灯珠的发光点都能被看到， 使灯带无法实现连续均匀的散光 效果。
后來市场上出现过一些用插件 LED灯珠作为光源的所谓霓虹灯和柔光灯，在用户使用的过 程中， 都发现一些致命的缺陷， 首先， 这类灯具的复杂内部结构导致灯具在生产加工过程中 加工工艺繁琐， 不仅需要编入多条导线， 每颗 LED灯珠不仅需要人工焊接在导线上， 而且在包 胶的过程中还需要通过特殊的结构固定， 成本高， 生产效率低； 其次， 灯具中的 LED灯珠被完 全包裹在塑胶内， 无法散热， 而且 LED灯具的寿命很大程度上依赖于灯具的散热结构和特性， ώ此导致整个灯具稳定性及寿命大打折扣； 因其产品外形及结构的特点， 导致产品在安装过 程中程序复杂， 灯具需要根据实际应用条件频繁的截断和续接（包括电路部分）， 使产品的使 用灵活度受到极大限制，最重要的是灯具的使用结构决定灯具线条固定能力和折弯性能不好， 线条定位不能精准， 折弯半径受限制等等， 使得 LED霓虹灯和柔光灯不能很好的满足图案或文 字设计的需求， 所以一直无法真正普及起来； 最后， 产品的售后维护也是问题， 不仅维护麻 烦， 而且维护成本不亚于重新购买一套。 发明内容
为了克服现有霓虹灯高成本、 高能耗、 低寿命以及现有的 LED霓虹灯及柔光灯不稳定、 安 装繁琐、 成本较高的缺点， 能更方便、 更简洁的开发生产出性价比更高、 便于使用安装的灯 具来应用到各个领域中， 特提供一种改进的新型 LED线条灯具。
该发明所采用的具体方案是： 灯具由基座、 若干 LED发光串、 若干透光条以及若干驱动电 源组成， 其中， 基座是透光条的载体， 透光条和基座是作为分离部件组装在一起的， 基座上 设有若干宽度适: '的沟槽或固定孔， 一个 LED线条灯具可以有多个基座构成； LED发光串是由 一串根据相应的电气原理相互连接的若干 LED光源构成； 透光条由具备较好的透光功能或散 光、 均光功能的材料制成， 比如塑胶或树脂或硅胶等； 透光条的_ .面 （发光面） 位于基座的 正面； LED发光串可以嵌入透光条中或尽量靠近或紧贴于透光条背面的表面上， 也可以通过基 座上的固定孔固定在基座上， 并且 LED灯珠的发光方向朝着透光条的正面； 透光条嵌入基座上 的沟槽中从而固定在基座上； 驱动电源与 LED发光串之间有若干导线连接。
基座可以是板状或双股金属丝或条状 U型槽等结构， 板状基座上的沟槽可以是通透的（沟 槽贯穿板的两面）， 也可以是不通透的， 形成闭环的通透沟槽可以是不连续的， 以保证闭环内 的基座不脱离整体基座， 此时可以用连续的透光条覆盖通透沟槽不连续的部分， 从而保证线 条的连续性； 板状基座上还可以设置若干固定孔， 用来固定 LED发光串上的每颗 LED光源， 透 光条通过板状基座上的沟槽固定并从板状基座的正面覆盖住每一个固定孔中的 LED光源； LED 发光串中的 LED光源可以是插件 LED灯珠， 也可以是贴片 LED灯珠， LED光源之间的连接可以通 过每颗插件 LED灯珠的管脚或者通过导线或者通过窄条状柔性电路等载体 （比如 FPC线路板） 实现， 从而形成 LED发光串， 电路连接的方式可以是串联或并联或串并混联等连接方式； 透光 条和 LED发光串可以做成不是一体的（相互独立存在）， LED发光串可以嵌入透光条中或者嵌入 并固定在板状基座上的固定孔中，也可以成使 LED发光串尽量靠近或紧贴于透光条背面的表面 上， LED光源的发光方向朝着透光条的发光面； 透光条和 LED发光串还可以做成一体的， LED 发光串在生产加工透光条的时候就被封装在透光条内部，灯珠发光方向朝着柔光条的发光面； 透光条背面可以带有夹槽， 背面的夹槽可以是单条沟状夹槽也可以是多条并列的沟状夹槽， LED发光串可以嵌入沟状夹槽中， 沟状夹槽对每个 LED光源进行部分包夹， 沟状夹槽的形状和 尺寸以可以把 LED发光串上的每个 LED光源嵌入其内并被固定住为宜； 透光条背面的夹槽可以 是有按一定分布密度和间距排列的若干小坑状夹槽，每个小坑可以单独嵌入 LED发光串上的一 个 LED光源， 对每个 LED光源进行多方位的包裹， 起到固定的作用。 透光条可以是实心的， 也 可以是空心的。组装好的 ώ插件 LED灯珠构成的线条灯具，在基座背面外露出来的若千插件 LED 灯珠管脚可以向两侧折弯， 使得 LED灯珠和透光条可以更牢固的固定在基座上。 首先， 根据基座的类型， 按所设计的灯光线条图案 （平面设计阶段的设计图中的灯光线 条图案） 在基座上加工出若干宽度适宜的沟槽， 或者按照所设计的灯光线条图案折弯若干双 股金属丝基座或者带有沟槽的条状 u型基座， 沟槽的宽度以可以紧紧夹住并固定住透光条为 宜。 然后： a ， 把透光条嵌入到基座上的沟槽中， 使得所有以透光条为线条构成的图案与最 初所设计的灯光线条图案基本一致； b ， 对于 LED发光串和透光条不是一体的状态下， 把 LED 发光串中 LED灯珠以相应的间距或分布密度从透光条的背面嵌入透光条中， 或者使 LED发光串 尽量靠近或紧贴于透光条背面的表面上， 使每颗 LED灯珠的发光方向朝着透光条的正面（发光 面）， 根据需要， a和 b的安装顺序也可以互换； 还可以根据设计图案在板状基座上加工出若干 相应密度和间隔的固定孔，固定孔的边上有用来固定透光条的沟槽，把 LED发光串中的每个 LED 光源通过固定孔固定在基座上， LED光源的发光方向朝向基座的正面， 然后把透光条通过板状 基座上的沟槽固定在基座上并从板状基座的. ΪΗ面覆盖住每一个固定孔中的 LED光源；透光条在 生产加工过程中， 可以根据需要在透光条的原材料里添加一定比例的添加剂， 使得其正面的 发光强度和均匀度到达理想效果， 还可以根据需要加工适宜软硬度的透光条， 保证线条灯具 的组装顺畅； 最后根据所选驱动电源的电气特性， 可以对其中的一些 LED发光串进行对接或截 断， 以保证驱动电源的最佳驱动特性。
本发明的积极效果如下： 首先， 可以完全替代传统室内霓虹灯以及 LED霓虹灯， 因其特有 的可拆装透光条设计结构， 使得其加工工艺简单， 方便安装和维护， 可以随意组合任意线条 图案， 这是传统霓虹灯所不能的， 并且克服传统霓虹灯高能耗、 高故障率、 安装复杂的缺陷， 而且重要的是可以使灯具整体厚度很薄， 基本上就是一张基板的厚度， 结构更为简洁， 颠覆 了传统广告发光体以灯箱为基本结构的概念。发光线条的宽度最小可以达到 2mm-3mm， 这是现 有的广告灯箱、 发光牌及发光标识所无法达到的； 其次， 本发明提供的 LED线条灯具相对比于 现有的 LED霓虹灯 /柔性灯带以及传统霓虹灯具和广告灯箱，因其特有的设计结构和安装方式， 使得实际的灯光图案几乎与设计图案相似度接近完美， 灯光线条圆滑、 曲度定位精确、 完全 可以保证灯光线条的整体连贯特性， 这是现有的各种类型霓虹灯所无法实现的效果， 最重要 的是由于所有 led光源所产生的光效都全部直接作用于透光条的发光面上， LED光源的发光效 率达到极致， 致使整个灯光线条图案亮度极高， 而且可以根据需求通过使用相应散光效果的 发光条， 使得整体线条灯具达到发光强度高但发光效果柔和不刺眼的双重视觉效果， 显得格 外的美观， 大幅提升灯光广告的视觉效果； 再者， 本发明涉及的灯具因其透光条特殊的夹槽 设计， 使得 LED灯珠以及管脚或导线外露， 可以完全解决现有的 LED霓虹灯及柔性灯条散热性 差的致命弊端， 从而提高灯具的工作稳定性， 延长灯具的使用寿命。 最后， 可以扩展作为室 内装饰照明灯具， 灯光柔和， 图案设计灵活， 是 LED广告和照明应用的一个全新的拓展。 附图说明
