在本发明一个较佳实施例中，所述通风散热管为玻璃纤维管，所述玻璃纤维管的熔点高于玻璃纤维板层的熔点。
在本发明一个较佳实施例中，所述弧形灯罩底部的边缘设置有延伸至玻璃纤维板层中的固定柱。
在本发明一个较佳实施例中，所述玻璃纤维板层中设置有与固定柱对应的安装孔。
在本发明一个较佳实施例中，所述安装孔中设置有导热胶。
在本发明一个较佳实施例中，所述固定柱、弧形灯罩和卡环为一体化透明塑料结构。
本发明的有益效果是：本发明指出的一种抗震加强的散热节能LED灯条，LED灯顶部被卡环限位，底部利用弹性导热柱进行支撑，结构稳定，抗震性好，通风散热管可以强制通风而带走玻璃纤维板层的热量，加强铜板导电线的散热，并利用散热层提升导热速度和散热效果，使用稳定性更好。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1是本发明一种抗震加强的散热节能LED灯条一较佳实施例的结构示意图。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1，本发明实施例包括：
一种抗震加强的散热节能LED灯条，包括：条形的电路板以及设置在其上方的一排LED灯8，所述电路板包括玻璃纤维板层1和散热层2，所述散热层2设置在玻璃纤维板层1的底部，提升玻璃纤维板层1导热效果和散热速度。
所述玻璃纤维板层1上表面间隔设置有两条铜板导电线13，所述LED灯8分别包括与两条铜板导电线13相连接的灯脚10，进行LED灯8的供电，工作过程中，铜板导电线13上的电流大，是产热集中区。
所述LED灯8底部与玻璃纤维板层1顶面之间设置有弹性导热柱7，所述玻璃纤维板层1中设置有分别位于铜板导电线13下方的通风散热管3，通风散热管3可以利用风扇强制通风而带走玻璃纤维板层1的热量，加强铜板导电线13的散热。
所述LED灯8上方设置有弧形灯罩6，所述弧形灯罩6中设置有与LED灯8对应的卡环9而对LED灯8顶部边缘进行限位，提升结构稳定性，再利用弹性导热柱7进行LED灯8底部的弹性限位，所述弹性导热柱7为底部固定在玻璃纤维板层1顶面的橡胶柱7，提升了抗震和导热效果。
所述散热层2为一层散热铜箔，散热铜箔比较轻薄，减少了电路板厚度的增加，但是导热速度快，散热效果好。
所述玻璃纤维板层1的上方设置有油墨层4，油墨层4的绝缘效果好，避免铜板导电线13的漏电问题，提升使用安全性。所述灯脚10分别焊接在两条铜板导电线13上，连接牢固，导电稳定。
所述通风散热管3为玻璃纤维管，所述玻璃纤维管的熔点高于玻璃纤维板层1的熔点，通风散热管3的安装有两种方式：
第一种是生产玻璃纤维板层1的时候，把通风散热管3预埋在玻璃纤维板层1中，玻璃纤维管的高熔点避免了通风散热管3的变形问题；
第二种是采用双层结构的玻璃纤维板层1，在上层玻璃纤维板底部设置有第一圆弧槽，在下层玻璃纤维板的上部设置对应的第二圆弧槽，把通风散热管3设置在第一圆弧槽和第二圆弧槽组成的圆孔中，然后复合。
所述弧形灯罩6底部的边缘设置有延伸至玻璃纤维板层1中的固定柱5，所述玻璃纤维板层1中设置有与固定柱5对应的安装孔12，安装便利。所述安装孔12中设置有导热胶11，提升了固定柱5在安装孔12中的结构稳定性，导热胶11把玻璃纤维板层1和铜板导电线13中的热量导入散热层2，提升了导热和散热效果。
所述固定柱5、弧形灯罩6和卡环9为一体化透明塑料结构，结构牢固，安装便利，对LED灯8的保护性好，而且透光性好，减少损耗。
综上所述，本发明指出的一种抗震加强的散热节能LED灯条，提升了结构稳定性，特别是抗震效果得以加强，适合车载设备使用，而且散热效果好，耐用节约，适用范围广泛。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
