在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图1-7所示，根据本实用新型的实施例的横泡式LED灯头注塑式防水灯串，包括：第一封装体10和多个通过主导线20连接且被封装在第一封装体10内的多个LED灯组30，每个LED灯组30包括第二封装体31、第一引出线32、正极与第一引出线32焊接的LED(标号为33)、与LED的负极焊接的降压电阻34以及与降压电阻34焊接的第二引出线35。第一引出线32的一部分、LED的全部或一部分、降压电阻34的全部或一部分以及第二引出线35的一部分被封装在第二封装体31内，LED的长度方向与主导线20的延伸方向相同。
根据本实用新型的实施例的横泡式LED灯头注塑式防水灯串，由于上述LED灯组上的所有接线端子被第二封装体31封装无主导线20外露，在通过第一封装体10进行第二次封装时，连接各个部分的电线不会发生移位，在保证整个横泡式LED灯头注塑式防水灯串的可靠性的前提下，提高了整体的防水性能好。并且，采用此种结构的横泡式LED灯头注塑式防水灯串在加工过程中操作简单方便，注塑方便简单，避免了生产过程中，对LED的损害，有效延长了LED的使用寿命，大大降低了生产过程中的不良比例。

需要说明的是，这种连接方式适用于，连接在电压为110V/230V的电路中，换言之，单颗LED引出的第一引出线32和第二引出线35分别构成正极和负极。单个LED灯组30的正极，与相邻的LED灯组30的负极相连接。从而将多颗LED依次串联形成一串，然后与灯串主导线20中的第一导线21及第二导线22并联在一起，形成一个通电电路。
如图3所示，根据本实用新型的一个实施例，主导线20可以包括第一导线21和第二导线22，每个LED灯组30的第一引出线32与第一导线21连接，每个LED灯组30的第二引出线35与第二导线22连接。
换句话说，在连接到电压为12V/24V的电路中时，第一导线21和第二导线22可以直接与LED正极和负极焊接在一起或者通过第一引出线32和第二引出线35焊接在一起。具体地，主导线20中的一根与LED正极连接，另外一根与LED负极连接在一起。这样多个LED便通过同样焊接方式并联在一起。连接后在，通过注塑成型第一封装体10完成最后的生产。
参见图4-7，根据本实用新型的实施例，第一封装体10在横泡式LED灯头注塑式防水灯串的延伸方向上构造成多个中部的径向尺寸大于两端的径向尺寸的灯罩部11。由此，可以便于LED的布置，且可以使横泡式LED灯头注塑式防水灯串100更加美观。进一步地，灯罩部11的横截面可以大体为圆形。并且，为了提高导光效果，灯罩部11上可以上设有筋条。
