具体实施方式
以下所述仅为本发明的较佳实施例，并非对本发明的范围进行限定。
实施例：如附图1、2、3、4、5、6、7以及附图8所示，一种LED照明灯，包括若干个灯管2以及分别设置在灯管2两端的灯头1和灯管底罩6，其中灯管2的数量至少为两个，如附图1中灯管2的数量为八个，均匀圆周排列在灯头1和灯管底罩6之间，灯头1、灯管2以及灯管底罩6是构成LED照明灯整体结构的三个组成部分。其中为了使得照明功能得以实现，灯管2能设有基板4，灯头1内设有电路板3，灯管底罩6内设有连接板7，而通电导线先经过电路板3，再经过基板4，最后到达连接板7,并返回构成回路，以保证最基本的照明功能得以实现，而基板4上的LED贴片5进行环向水平发光，作为主要照明部位，连接板7下端面上的辅助LED贴片604进行向下的发光照明，并配合灯管底罩6中罩体内底面609的反射光线方式，来进行LED照明灯的上部照明点亮，以达到全方位发光的目的
在本实施例中，灯管底罩6分下部的第二罩体602以及上部并与灯管2连接的第一罩体601，而连接板7就设置在第一罩体601与第二罩体602扣合后形成的封闭腔内。另一方面，出于提高散热效果和进一步增大光透过量的目的，第一罩体601上开设有第一开孔605和设置在第一开孔605边沿上，并向第二罩体602方向延伸的第一开孔壁606；第二罩体602上开设有第二开孔607和设置在第二开孔607边沿上，并向第一罩体601方向延伸的第二开孔壁608，更重要的是，第一开孔壁606与第二开孔壁608之间卡接固定，从灯管底罩6的中部保证了腔体的封闭性，再配合第一罩体601和第二罩体602在外部圆周上的卡合固定作用，能保证整个灯管底罩6具有一个全面封闭的内腔，用来设置连接板7。
在附图1中，灯管底罩6出于外观需要，第二罩体602下端面上设置一个截面为半圆的环形体，而罩体内底面609就设置在环形体的内侧，其中罩体内底面609为具有一定轴向宽度的环形平底，以用于提高发射光线的效果。另一方面，用于连接板7设置在具有一定深度的第一罩体601内，并由基板4通过焊接的方式来来达到固定连接板7的目的，所以第二罩体602的下端面也可以为平面，同样不影响其反射光线以进行辅助照明的功能。
从灯管底罩6向上设置有两个连接部位，即灯管2和基板4，其中灯管2的侧面抵在连接板7上端面上，并穿过第一罩体601上开设的罩体连接孔603向上设置，而灯管2与罩体连接孔603之间的接触部位，涂有用于相互固定的粘结剂，其中基板4与连接板7之间的连接部位通过焊接方式实现两个目的：第一，焊接固定连接板7，使得连接板7在灯管底罩6 的开腔内不至于出现晃动；第二，采用锡焊的方式，将辅助LED贴片604与LED贴片5进行连通导电，以保证发光效果。此外，玻璃材质的灯管2与连接板7接触，将灯管2同时作为LED贴片5与辅助LED贴片604的散热外部结构，可以进一步保证连接板7的散热效果，避免被封闭设置的连接板7发生过热问题。
沿着灯管2方向往上，在灯管2内，整根基板4一侧设置有若干个LED贴片5，其中LED贴片5的数量至少为一个，如附图8中LED贴片5的数量为七个，而基板4的另一面通过导热粘结层8粘结固定在灯管2的内部，而导热粘结层8同样具有两个目的：第一，固定基板4，避免基板4在固定连接板7和与电路板3连接时都能保持稳固；第二，将LED贴片5发光过程中产生的热量经过基板4，再经过导热粘结层8，最终传递给灯管2进行向外发散，以保证散热效果。本实施例相对于现有的将基板悬空设置在灯管内并通过空气传递热量的方式，具有热量传递速度快、效果好的优点，能进一步保证LED照明灯的散热效果。
至于灯管2的内环面上，涂有一层用于遮盖LED贴片5发光以保证防刺眼效果的涂层9，这是因为在现有技术中，使用者与LED贴片之间仅仅隔着一层透明玻璃，虽然这样能较好的保证光亮程度，但是在使用过程中容易发生刺眼的有害问题，所以涂层9在保证基本的、足够的透光率前提下，进行遮盖防刺眼操作，使得整个LED照明灯在使用过程中即使是直视时都不会发生刺眼问题。此外，设置在基板4上的LED贴片5具有数量多、形状小的特点，当LED贴片5暴露在使用者目前时，大大影响整个LED照明灯的整体性，降低其观感，而涂层9能遮盖LED贴片5，使得整个LED照明灯中段即灯管2部位呈一个整体，提高使用效果。
灯管2上端穿过底板开孔108并与灯头底板101实现插接并由粘结剂保证粘结固定，而灯管2的上端与灯头底板101的底面平齐，以避免因为凸出设置而影响电路板3在灯头1内的安装固定，而基板4的高度也不宜超出灯管2，以节省灯头1内的空间，在若干个基板4中，会挑选相邻的两个基板4作为基板连接线303的安装连接部位，即如附图8所示，而基板连接线303与电路板主体302连接，电路板主体302通过导电连接头部连接线304与导电连接头10连接，而导电连接头10安装在照明灯插头上，已完成整个的通电导通操作。
另一方面，导电连接头10可以是螺口式或者插口式，但不管是哪种方式，导电连接头部连接线304的数量为两根，一根连接位于灯头连接柱103上的侧边，一根连接灯头连接柱103上端的另一个连接凸出端，以满足安装电路中零线火线的设定。
作为LED照明灯的顶部连接部，灯头1主要用于固定并封盖保护电路板3，即如附图4、附图5所示，电路板3设置在灯头底板101上，并通过凸出固定端301开合在灯头凸出 槽体104的开槽内的方式来保证固定作用，通过灯头罩102来保证封盖保护作用，而灯头底板101上设有向上设置的环形壁，用于与灯头罩102进行卡扣连接，也可以通过粘结固定。
在本实施例中，灯头凸出槽体104向灯管底罩6方向地向下设置，使得电路板3可以呈两端小、中间大、整体竖向长度长的特点，而整个电路板3竖直设定，各类常规的电子元器件305设置在电路板3上，这相较于传统模式，即电路板制成圆形，并与灯头底板101平行设置这样的现有技术方式，本实施例中电路板3使得灯管2上端开口不会封闭，即灯管底罩6的反射光线经过灯管2能顺利达到并点亮灯头罩102，避免现有技术中灯头罩102处呈灰暗状态的问题。
另一方面并且仍具有重要意义的是，灯头1与第一开孔605和第二开孔607在灯管底罩6上形成的贯穿孔都具有提高散热效果的作用，在本实施例中，温度最高、热空气大量发散开来的部位是中段的灯管2处，而第一开孔605和第二开孔607在灯管底罩6上形成的贯穿孔作为下端进入相对较冷空气的位置，灯管底罩6上也设有用于相对较冷空气向下进入到灯管2附件的通道，即灯头连接柱103与灯头罩102之间的开口空隙106和灯头凸出槽体104槽底的槽底开口107，共同组成上部进空气的开口，实现整个LED照明灯中部散发热空气、上下进入冷空气到灯管2中部的散热模式，保证整体的散热效果，即如附图6所示。
在灯头1上，灯头连接柱103通过连接块105与灯头罩102连接，并形成用于空气向下进入灯头1的开口空隙106，而底板开孔108在连接灯管2时，其开孔周边上设有用于增大连接面积的开孔凸出环109，开孔凸出环109与灯管2的接触位置可以通过粘结剂完成粘结固定，而当电路板3的宽度以及电子元器件305的排布适宜时，灯管底罩6的反射光线经过灯管2，即如附图1所示，在八个灯管2的上端开口处均不会被遮挡，反射光线的通道也是畅通状态，而反射光线能顺利达到灯头罩102并将之照亮。
在现有技术中，基板悬空设置在上部电路板上，基板上的LED贴片需要导向一一串联后再折返向上至上部电路板，此时基板上需要上下设置两根导线，这在较窄的基板上是会增大制作难度的，而在本实施例中，连接板7的设置并连接若干个灯管2，使得基板4上只需设置一根上行或下行通电方向的导线即可，这能大大降低基板4的制造工艺。
在本实施例中，灯管底罩6作为一个主透光、副发光的部位，而且为LED照明灯落地后首先与地面碰触的部位，所以要求灯管底罩6一要具有高强度，二要具有较高的透光度，所以本实施例中采用聚碳酸酯(PC)材质来制作，另一方面灯头1无需再向上透过光亮，可以仅仅作为一个待装饰部位，所以不需要价格相对较高的PC材质，在本实施例中，灯头1的材质为PBT，而涂层9的材质为硅胶。
本实施例中，LED照明灯的发光情况为：中段环向向外主发光、灯管底罩6向下主发光以及灯管底罩6向上辅助发射光线发光以点亮灯头罩102的方式，散热情况为：中段环向向外发散热空气和上下进入补充相对冷空气的方式，而防刺眼情况则通过灯管2内的涂层9在透光前提下实现遮光防刺眼，以保证整个LED照明灯的全方位发光、散热效果好以及防刺眼这三个突出特点。
上面结合附图对本发明的实施方式作了详细说明，但是本发明不限于上述实施方式，在所述技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下做出各种修改。这些都是不具有创造性的修改，只要在本发明的权利要求范围内都受到专利法的保护。
