具体实施方式
下面，结合附图以及具体实施方式，对本实用新型做进一步描述：
如图1-4所示，一种具有高效散热功能的LED灯，包括灯壳1、设置在灯壳底部的LED模块2、设置在灯壳底部下方的灯座3以及设置在灯座内的电路板4；所述灯壳1底部开设有两个通孔101，所述LED模块2在灯壳底部其中一个通孔的位置上设置有缺口201；所述灯座底的中部设置有多个中部排气孔303，灯座底部设置有底部排气 孔305。
通过开设在灯壳底部的通孔以及LED模块上的缺口，一方面，设置在LED模块上的缺口可供线路走线，使LED模块与设置在灯座内的电路板电性连接；另一方面，通孔与缺口位置对应，使灯壳和灯座的内腔连通，有助于使在灯壳内腔被加热的气体流动到灯座内腔，从而通过设置在灯座上的多个中部排气孔和底部排气孔排除，使内腔的热气能有效排出，起有效的散热作用。
所述灯座3包括上灯座301和与上灯座一体成型的下灯座302，上灯座底部直径大于下灯座顶部直径；所述中部排气孔303开设在下灯座顶部边缘上，所述下灯座底部向下延伸有用于遮挡中部排气孔的遮挡部304，使使用者在水平方向上也不能直接看到中部排气孔，一定程度上保证了灯外形的美观。所述底部排气孔305开设在下灯座底部，底部排气孔设置的形状，则在保证外壳底部强度的同时，使排气的面积最大化。
所述灯壳内还设置有紧贴在灯壳内侧的铝散热器5。所述铝散热器内侧设置成反光杯形状。一方面，铝散热器可将内腔的热量更易于传导到灯壳上，从而将热量散发到外界，达到散热效果；另一方面，更优的，散热器内侧可设置为反光杯形状，起到提高光源参数和效果的作用。
所述灯壳底部与灯座顶部设置有多个位置对应的快装卡扣结构6。该快装卡扣结构能起快捷安装的效果，结构详见图3。在实际使 用中，卡扣形成的缺口，亦有助于灯体散热。
作为优选地方案，所述LED模块通过有助于散热的散热胶(图中未示)与灯壳底部贴合，亦有助于将LED模块产生的大量热量传到灯座内，从而散热。
本实用新型的LED灯其散热过程如下：
本实用新型的LED灯的灯头向上，出光面向下为主要应用的形式；
在实际使用中，LED模块会产生较大的热量，使灯壳内腔的空气加热。由于灯壳底部设有底部出气孔，所以较热的空气将会向上向较凉的灯座内腔流动。同理，由于灯座内的电路板会产生一定的热量，加上灯壳传递到灯座的热量，使灯座内空气温度高于外界，因为会向上通过灯座底部的排气孔向上排出。按照这个原理，在LED灯内形成自下而上的排气通道，从灯座底部排气孔排出，从而形成像“烟囱”一样原理的散热效果。
而底座中部设置的数个中部排气孔，有利于热气排出；及LED模块和灯壳底部设置的散热胶，有利于LED模块的热量传到灯座上。这两个结构与上述的排气原理相结合，提供了散热效果。
另外，铝散热器则实现通过灯外壳的直接散热，而卡扣形成的缺口，亦有助于灯体散热。
因此，本实用新型提出的一种具有高效散热功能的LED灯，在实现了结构简单、安装快捷的前提下，保证了灯体的散热性能。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本实用新型权利要求的保护范围之内。
