Description

LED灯串
技术领域
[0001] 本发明涉及照明灯具领域， 尤其涉及一种悬挂使用的 LED灯串。
背景技术
[0002] LED灯串的结构主要由一条灯线和连接在其下方的多个灯具构成。 由于 LED灯 串在户外悬挂使用较多， 因此各部件的连接强度、 防水性、 拆卸安装的便利性 非常重要。 目前灯具光源普遍采用 LED灯板， 灯具结构包括灯座、 LED灯板、 导 光柱、 灯罩和固定座， 灯罩与灯座相连， 特定结构的固定座用于安装 LED灯板和 导光柱。
技术问题
[0003] 现有灯具存在的不足是 LED灯板需要通过固定座安装在灯座上， 结构复杂导致 生产成本高， 拆卸维修不方便。
问题的解决方案
技术解决方案
[0004] 为了解决上述问题， 本发明的目的在于提供一种结构简单， 连接强度好的 LED 灯串。
[0005] 为了实现上述的目的， 本发明采用了以下的技术方案： 包括灯线和连接在其下 方的多个灯具， 每个灯具均通过导线连接灯线； 灯具包括灯座、 接线端子、 LED 灯板、 导光柱和灯罩， 导线顶端连接灯线， 导线底端穿过灯座连接接线端子， 接线端子与其下方的 LED灯板电连接； 灯座内设有限位台阶， 限位台阶下方的灯 座内侧设有内螺纹； 灯罩顶部外侧设有外螺纹， 灯罩与灯座螺纹连接将导光柱 限位在灯罩内； 灯座内的导线伸展状态下长度大于灯座内孔的长度； 导光柱是 透明塑料， 导光柱的上部是安装 LED灯板的透明杯体， 导光柱的下部用于导光的 透明柱体， 透明杯体顶部设有向外延伸且其连为一体的限位翻边， 限位翻边顶 面抵在限位台阶上， 灯罩顶部抵在限位翻边底面上； 限位翻边上设有与其连为 一体的卡扣， 透明杯体上设有缺口， 卡扣处于缺口处， 卡扣底部与透明杯体底 部之间留有容纳 LED灯板的间隙， 卡扣将 LED灯板固定在透明杯体内； 透明柱体 下部内设有由上至下逐渐变大的锥形孔。
[0006] 作为优选， 灯座由外壳和内架固定连接构成， 限位台阶和内螺纹均处于内架内 侧； 外壳是 PVC外壳， 内架是 PBT内架， 灯座由 PVC外壳和 PBT内架通过注塑包 胶构成； 导线穿过 PBT内架通过与 PBT内架无缝连接； 灯座的结构解决了 LED灯 串对于户外使用防水性能的问题， 灯座不仅连接强度好， 而且防水性也好， 尤 其是外壳和内架的材质及注塑包胶的生产方式对于灯具的防水和连接强度非常 重要。
[0007] 作为优选， 灯罩是 PC透明灯罩， 悬挂使用吋适当碰触不易碎， 适合户外使用， 灯罩上外螺纹下方套设有密封圈， 进一步提升了防水性能。
[0008] 作为优选， 透明杯体截面呈圆形； 缺口是沿透明杯体直径线排列的一对， 卡扣 是与缺口位置匹配的一对， 透明杯体和卡扣可以平均受力， 防止透明杯体和卡 扣受力破损的效果更好。
[0009] 作为优选， 透明柱体由上至下分为三部分， 顶部是加强连接部， 加强连接部呈 上大下小的锥台形， 中部呈圆柱形， 底部是主要扩散部， 锥形孔处于扩散部内
， 加强连接部和主要扩散部直径大于中部的直径。 由于透明杯体和卡扣经常受 力， 因此加强连接部可以增加导光柱的强度， 加强连接部和主要扩散部直径大 于中部的直径， 即节约了材料又增加光效。
[0010] 作为优选， 接线端子由相互匹配的母接线端和子接线端构成， 导线底端与母接 线端固定连接， 子接线端固定在 LED灯板的顶面上， 使用方便。
[0011] 作为优选， 灯线上与导线连接处设有连接头， 连接头顶部设置挂钩孔， 便于悬 挂， 使用方便。
发明的有益效果
有益效果
[0012] 采用上述技术方案的 LED灯串， 限位翻边顶面抵在限位台阶上， 灯罩顶部抵在 限位翻边底面上， 限位翻边即用于导光柱的安装限位， 同吋用于安装与其连为 一体的卡扣， 透明杯体上设有缺口， 卡扣处于缺口处， 卡扣将 LED灯板固定在透 明杯体内。 采用了上述结构的导光柱， LED灯板直接安装在导光柱上， 相对于传 统的 LED灯串取消了用于安装 LED灯的固定座结构， 减少了部件的使用， 安装和 拆卸更加方便。 由于拆卸或安装 LED灯板吋经常会对卡扣处进行操作， 而导光柱 是透明塑料， 采用缺口和卡扣的结构可以便于透明杯体受力吋的适当变形， 进 而防止透明杯体和卡扣受力破损。 透明柱体下部内设有由上至下逐渐变大的锥 形孔， 锥形孔可以增加光效。 灯座内的导线伸展状态下长度大于灯座内孔的长 度， 优点是拆装导光柱吋可以将接线端子拉出灯座外操作， 使用更加方便， 不 拆卸吋导线通过导光柱限位被隐藏在灯座内， 结构合理。 综上所述， 该 LED灯串 的优点是结构简单， 连接强度高， 安装或拆卸方便， 生产成本低。

[0017] 如图 1、 图 2和图 3所示的 LED灯串， 包括灯线 1和连接在其下方的多个灯具 9， 每个灯具 9均通过导线 2连接灯线 1， 灯线 1上与导线 2连接处设有连接头 3， 连接 头 3顶部设置挂钩孔 31， 便于 LED灯串的悬挂， 使用方便。
[0018] 灯具 9包括灯座 4、 接线端子、 LED灯板 8、 导光柱 6和灯罩 5， 导线 2顶端连接灯 线 1， 导线 2底端穿过灯座 4连接接线端子， 接线端子与其下方的 LED灯板 8电连接 。 接线端子由相互匹配的母接线端 71和子接线端 72构成， 导线 2底端与母接线端 71固定连接， 子接线端 72固定在 LED灯板 8的顶面上， LED灯板 8上的 LED灯朝向 下方。 灯座 4内设有限位台阶 421， 限位台阶 421下方的灯座内侧设有内螺纹 422 ， 灯座 4由外壳 41和内架 42固定连接构成， 限位台阶 421和内螺纹 422均处于内架 内侧， 具体的， 外壳是 PVC外壳， 内架是 PBT内架， 灯座由 PVC外壳和 PBT内架 通过注塑包胶构成。 导线 2穿过 PBT内架通过与 PBT内架无缝连接， 灯座 4的结构 解决了 LED灯串对于户外使用防水性能的问题， 灯座 4不仅连接强度好， 而且防 水性也好， 尤其是外壳和内架的材质及注塑包胶的生产方式对于灯具的防水和 连接强度非常重要。 灯座 4内的导线 2伸展状态下长度大于灯座 4内孔的长度， 拆 装导光柱 6吋可以将母接线端 71和子接线端 72拉出灯座 4外， 操作更加方便。 灯 罩 5顶部外侧设有外螺纹 51， 灯罩 5与灯座 4螺纹连接将导光柱 6限位在灯罩 5内。 灯罩 5是 PC透明灯罩， 悬挂使用吋适当碰触不易碎， 适合户外使用， 灯罩 5上外 螺纹 51下方套设有密封圈 52， 进一步提升了防水性能。
[0019] 导光柱 6是透明塑料， 导光柱的上部是安装 LED灯板的透明杯体 62， 导光柱的 下部用于导光的透明柱体 63， 透明杯体 62顶部设有向外延伸且其连为一体的限 位翻边 61， 限位翻边 61顶面抵在限位台阶 421上， 灯罩 5顶部抵在限位翻边 61底 面上。 限位翻边 61底部设有与其连为一体的卡扣 64， 透明杯体 62截面呈圆形， 透明杯体 62上设有缺口 621， 卡扣 64处于缺口 621处， 卡扣 64底部与透明杯体 62 底部之间留有容纳 LED灯板的间隙， LED灯板 8被卡扣 64卡紧在透明杯体 62内。 由于拆卸或安装 LED灯板 8吋经常会对卡扣 64处进行操作， 而导光柱 6是透明塑料 ， 因此采用缺口 621的结构可以便于透明杯体 62和卡扣 64受力吋的适当变形， 进 而防止透明杯体 62和卡扣 64受力破损。 缺口 621是沿透明杯体直径线排列的一对 ， 卡扣是与缺口位置匹配的一对， 可以平均受力， 防止透明杯体 62和卡扣 64受 力破损的效果更好。 卡扣 64安装的结构和位置合理， 连接强度好， 例如相对于 卡扣 64安装在透明杯体 62的内侧壁的结构连接强度更好。
[0020] 透明柱体 63由上至下分为三部分， 顶部是加强连接部， 加强连接部呈上大下小 的锥台形， 中部呈圆柱形， 底部是主要扩散部， 主要扩散部内设有锥形孔 631， 锥形孔 631的截面是由上至下直径逐渐变大的锥形， 加强连接部和主要扩散部直 径大于中部的直径， 由于透明杯体 62和卡扣 64经常受力， 因此加强连接部可以 增加导光柱的强度， 锥形孔 631可以增加光效。
[0021] LED灯串拆装方便， 通过导线 2顶端与灯线 1的分离可以将灯具 9与灯线 1拆幵。
拆卸灯具 9吋， 将灯罩 5和灯座 4通过螺纹拧幵， 灯罩 5与灯座 4分离， 灯罩 5被拆 下。 灯座 4内的导线 2伸展状态下长度大于灯座内孔的长度， 既可以在灯座 4外操 作母接线端 71和子接线端 72的分离， 方便的将导光柱 6及其上的 LED灯板 8拆下， 通过卡扣 64受力可以将导光柱 6和 LED灯板 8拆幵， 子接线端 72—般与 LED灯板 8 焊住不拆开。 导线 2底端与母接线端 71可以拆开， PVC外壳、 PBT内架和导线 2固 定连接不拆开。
上述连接头 3可以采用密封的结构， 灯线 1与灯具 9就拆不开， 即灯具 9与灯线 1 是否可拆可以选择。
