Description
本实用新型涉及装饰灯领域,尤其涉及一种新型的啤注式灯头。
灯串是常见的灯饰。现有的装饰灯串的啤注式灯头所采用的生产工艺一般为:
将LED与导线连接后放置于透光泡壳内,然后在透光泡壳的尾部注塑灯座,
该灯座包覆导线、导线与LED之间的电连接点。如申请号为200410007211.4的中国专利,其公开的加套发光二极管组件包括以下生产工艺:将LED与电线组连接后放置于透光罩的空腔中,在透光罩的开口处注塑包覆电线组、触点组与电线组之间的电气连接和部分透光罩的整体模制塑料套。依照该种工艺所生产的啤注式灯头与组合式灯头、灌胶式灯头相比,防水和绝缘性能得到了很大提高,但仍然存在以下弊端和不足:首先,在注塑灯座的过程中,温度较高的胶料有可能冲入泡壳空腔,堵塞泡壳和烫坏LED,严重影响良品率;其次,注塑灯座所采用的是PP等较硬的塑料,而包覆导线的是柔韧性较好的橡胶,两者的硬度和延展性不一致导致注塑灯座和导线之间存在不可避免的间隙,在长期严苛的室外使用环境中,这些空隙有可能导致水分进入灯头内部,造成损坏甚至发生安全事故。
本实用新型的目的是提供一种新型的啤注式灯头,从根本上解决注塑胶料冲入泡壳和防水性能差的问题。
一种新型的啤注式灯头,其特征在于:包括
一LED,包括封装体和灯脚;
与所述LED的灯脚电连接的导线;
一内部有空腔的透光泡壳,所述LED的封装体容置于空腔内;
安装于所述透光泡壳的开口端、用于密封空腔的密封件,所述密封件设置有与LED的灯脚相匹配的通孔,所述LED的灯脚穿过通孔,所述密封件部分容置于透光泡壳的空腔内部,且LED的灯脚与通孔间填充有树脂;
通过注塑成型的灯座,所述灯座包覆透光泡壳的尾部、部分导线、LED的灯脚与导线之间的电连接点、密封件露在泡壳外的部分。
进一步地,所述密封件包括***部,所述***部容置于透光泡壳的开口端内部。
进一步地,所述密封件还包括止推部,所述止推部突出于***部底端,且止位在透光泡壳的开口端外沿。
进一步地,所述密封件设置有一圆形凹槽,所述圆形凹槽包围LED的部分封装体。
进一步地,所述LED的封装体与密封件紧密贴合
进一步地,所述通孔从上到下由宽变窄。
进一步地,所述LED的灯脚之间设置有一隔离件,所述隔离件位于密封件的下方,所述隔离件将LED的灯脚及部分导线隔离。
进一步地,所述透光泡壳的外表面设置有至少一环形凹槽,所述环形凹槽被灯座包覆。
进一步地,所述树脂为环氧树脂或有机硅树脂。
由于LED的灯脚与密封件的通孔间填充有树脂,在灯座注塑成型的过程中防止胶料从灯脚与透光泡壳的密封件之间的空隙冲入泡壳空腔,堵塞泡壳和烫坏LED,在长期的使用过程中也避免了从导线和灯座之间的空隙进入的水分进一步渗入泡壳空腔,极大的提高了灯头的防水性能。

下面结合附图,通过实施例对本实用新型作进一步说明。
所述实施例仅用于说明本实用新型的技术方案,并不构成对本实用新型权利保护范围的限定。
参照图1、图2,本实用新型的啤注式灯头包括透光泡壳3和灯座6,导线2连接多个灯头形成灯串。
参照图3至图5,本实用新型实施例一的啤注式灯头包括LED1,与LED1的灯脚11电连接的导线2,内部有空腔的透光泡壳3,安装于透光泡壳3的开口端的密封空腔的密封件4,通过注塑成型的灯座6。LED1包括封装体12和灯脚11,封装体12容置于透光泡壳3的空腔内。密封件4设置有与LED1的灯脚11相匹配的通孔。密封件4包括***部41和止推部42,***部41容置于透光泡壳开口端内部,止推部42突出于***部41底端,且止位在透光泡壳3的开口端外沿。LED的封装体12与密封件4紧密贴合,灯脚11穿过通孔与导线2实现电连接。灯座6包覆部分导线、LED1的灯脚11与导线2之间的电连接点5和密封件4露在泡壳外面的部分。
为了便于LED的灯脚11穿过密封件4,密封件4的通孔从上到下由宽变窄,灯脚11与通孔之间存在细微的间隙。为了填充这些间隙,可以预先在灯脚11或通孔上涂上树脂7
再将灯脚11穿过通孔。树脂7可以是环氧树脂或有机硅树脂。
LED
的灯脚11之间设置有一隔离件8,隔离件8位于密封件4的下方,该隔离件8将LED的灯脚11及部分导电线隔离。
透光泡壳3的外表面设置有一环形凹槽9,灯座6在注塑成型后包覆环形凹槽9,两者之间固定卡死。
参照图6、图7,在实施例二中对密封件4作出进一步改进。密封件4设置有圆形凹槽43,当把LED与密封件组装后,圆形凹槽43包围LED的部分封装体12,起到更好的密封作用。其他要点包括LED1、灯脚11和树脂7两者大体一致,在此不作多述。
以上所述仅以方便说明本实用新型,在不脱离本实用新型的创作精神范畴内,熟知此技术的本领域的技术人员所做的任何简单的修饰与变形仍属于本实用新型的保护范围。
