下面将对本发明一种 LED灯带的快速封胶方法的具体实施例进 行更详细的 4 述。
但是， 本领域技术人员应当理解， 以下所述仅是举例说明和描述 一些优选实施方式， 其它一些类似的或等同的实施方式同样也可以用 来实施本发明。
1、 透光胶条膜具的制作
用依照 LED灯带 1(如图 1、 图 2所示）， 如线路板 1A上布置的 元件 1B、 1C的位置间距， 并根据需要将 LED灯发光面的模具横截面 制作成例如半圓形、 孤形状、 多边状、 弧形状与多边状的组合、 或者 其它任何合适形状的开放型透光胶条模具、 半封闭型的透光胶条模 具、 或者是接近全封闭型的透光胶条模具， 并且将模具设计成让根据 该模具成型后的透光胶条，与在 LED灯带 1上元件对应的位置处，形 成有用于容纳元件 1B、 1C的、 与元件 1B、 1C具有基本上互补形状 的凹穴 2A、 3A或 4A， 如图 3-5所示。
2、 透光胶奈的制作 将透光胶， 利用如上所述的相应的透光胶条模具灌注成型， 制作 成透光胶条， 例如如图 3所示的透光胶条密封粘贴面为开放型的弧形 透光胶条 2，它形成有开放型的凹穴 2A， 凹穴 2A的内部形成粘贴面； 或者如图 4所示的半封闭型的弧形透光胶条 3， 它形成有半封闭型的 凹穴 3A, 其内部形成粘贴面， 半封闭型凹穴 3A与开放型凹穴 2A的 主要区别在于， 凹穴 3A的内部被与透光胶条 3整体成型的半延伸部 3B部分地封闭， 留出一个较大的槽口 3C未被封闭， 如图 4所示； 或 者如图 5所示的接近全封闭型的弧形透光胶条 4, 它形成有接近全封 闭型的凹穴 4A, 其内部形成粘贴面， 接近全封闭型凹穴 4A与半封闭 型凹穴 3 A的主要区别在于，接近全封闭型凹穴 4A的内部被与透光胶 条 4整体成型的延伸部 4B几乎全部封闭， 只留出一个艮窄的狭缝 4C 未被封闭， 如图 5所示， 其中狭缝的宽度要远远小于半封闭型透光胶 条 3的槽口 3C的宽度。
本发明的这种透光胶条的构造与现有技术相比， 具有显著的优 点。 首先， 本发明的这种透光胶条的构造使得不再采用传统滴胶的方 式， 而是采用贴胶粘合的方式， 从而避免了传统滴胶的所有缺点。 另 外， 本发明的这种透光胶条的构造与现有技术的封胶套管的本质区别 在于，封胶套管是全封闭型的，而本发明的透光胶条不是全封闭型的。 现有技术的采用封胶套管对 LED灯带进行封胶需要顺着套管的延伸 方向 (纵向)来进行， 不仅费力且费时， 封胶组装的难度极大， 而且对 于长的 LED灯带则根本无法将其装进套管，从而无法完成封胶。而本 发明的这种透光胶条的构造不是全封闭的， 无论是在涂胶或贴胶步骤 上， 还是在粘贴固定步骤上， 可以直接从凹穴的敞开部位来进行， 对 于能够弹性变形的柔性胶条而言， 还可以使胶条弹性变形而使得狭缝 4C或槽口 3C的宽度暂时地变大而加快 LED灯带的粘贴固定步骤， 如下所示。
3快速封胶
有下述几种优选的快速封胶方法： a、在 LED灯带上喷涂上一层胶粘剂， 例如透明胶水 5 (如图 6-8 所示。 但是本领域技术人员显然可以理解， 在其它的实施方式中， 例 如如图 9-11所示， 可以省略透明胶水 5 ) ， 然后将制作好的透光胶条 与 LED灯带对位粘贴结合在一起； 或者
b、用预先开有元件窗口的热熔型的胶膜对位贴在 LED灯带 1上， 然后将制作好的透光胶条与 LED灯带对位热压粘贴结合在 LED灯带 本体 1上； 或者
c、用预先开有元件窗口的热固型的胶膜对位贴在 LED灯带 1上， 然后将制作好的透光胶条与 LED灯带对位热压粘贴结合在 LED灯带 本体 1上； 或者
d、 利用预先开有元件窗口的热敏胶对位贴在 LED灯带上， 然后 将制作好的透光胶条与 LED灯带对位粘贴结合在 LED灯带本体 1上； 或者
e、 用高分子材料制成的透光胶条， 通过加热使其接触面融化成 有胶粘性， 然后与 LED灯带对位、 直接压粘结合在 LED灯带本体 1 上。
这样， 就可以如上所述的各种方式完成 LED灯带的快速封胶， 但是， 本领域技术人员可以理解， 本发明并不限于如上所述的这些工 艺， 基于这些工艺对于本领域设计人员显而易见的任何其它等同的工 艺或变型都属于本发明的范围。
如图 6所示， 为 LED灯带 1与开放型的透光胶条 2对位、 粘贴 结合在一起的横截面结构示意图。如图 7所示，为 LED灯带 1与半封 闭型的透光胶条 3对位、 粘贴结合在一起的横截面结构示意图。 如图 8所示， 为 LED灯带 1与接近全封闭型的透光胶条 4对位、 粘贴结合 在一起的横截面结构示意图。 如上所述， 尽管在这些附图 6 - 8 中针 对上述方法 a显示了喷涂上的一层透明胶水 5, 但是本领域技术人员 显然可以理解， 在其它的实施方式中， 例如如上所述的工艺步骤 c - d 中， 也可以不使用透明胶水 5， 如图 9 - 11所示。 其中， 图 9为根据 本发明又一实施例的 LED灯带用的开放型的弧形透光胶条封胶后的 横截面结构示意图， 除了没有采用胶粘剂， 例如透明胶水 5之外， 其 结构基本上类似于图 6。 图 10为根据本发明又一实施例的 LED灯带 用的半封闭型的弧形透光胶条封胶后的横截面结构示意图， 除了没有 采用胶粘剂， 例如透明胶水 5之外， 其结构基本上类似于图 7。 图 1 1 为根据本发明又一实施例的 LED灯带用的接近全封闭型的弧形透光 胶条封胶后的横截面结构示意图， 除了没有采用胶粘剂， 例如透明胶 水 5之外， 其结构基本上类似于图 8。
通过本发明的透光胶条的构造， 由于 LED灯带 1的 LED发光面 被封装在透光胶条的凹穴内， 因此可以涉及透光胶条的出光部位， 例 如图 3 - 5 所示的透光胶条的曲面部位， 使得透光胶条可兼顾封装结 构和光学透镜的作用。 因此， 还可通过改变透光胶条的外曲面和凹穴 的内表面的形状， 来获得各种需要的输出光形， 满足不同实际应用的 需求。 对于本领域技术人员而言， 由于透光胶条可由模具模塑制成， 因此可以非常方便地改变透光胶条的形状来制成不同的二次光学曲 面，从而达到二次光学设计的目的，用于对 LED灯发出的光进行散射 和折射处理， 以满足各种应用场合的个性化光学需求。
本发明的这种 LED灯带封胶构造和生产技术简单、 操作便利、 快速， 生产效率非常高， 与传统的 LED灯带封胶构造和技术相比， 是 一种投资少、 占用空间小， 生产效率能提高数十数百倍的新技术， 并 能对 LED灯发出的光进行散射和折射处理。
以上结合附图将方法具体实施例对本发明进行了详细的描述。但 是， 本领域技术人员应当理解， 以上所述仅仅是举例说明和描述一些 具体实施方式， 对本发明的范围， 尤其是权利要求的范围， 并不具有 任何限制。
