Description

一种斗胆灯
技术领域
本发明涉及灯具领域，特别是一种斗胆灯。
背景技术
众所周知，LED灯因具有能耗低、使用寿命长和光照亮度强等优点而受到人们的青睐。但是LED灯通电发光时会产生大量的热量，若不能将该些热量及时散发至外界环境中去，则会导致LED灯光衰减严重。
现市面上的LED灯一般都配备了散热器，但是该些LED灯的导热效率低，不能通过整个散热器进行散热，散热效果较差。
发明内容
为了解决上述问题，本发明的目的在于提供一种结构简单，同时散热效率高的斗胆灯。
本发明为解决其技术问题而采用的技术方案是：
一种斗胆灯，包括：
一安装基座；
一个以上的LED光源，所述LED光源设置于所述安装基座上；
一散热器；
所述散热器上还设置有一用于导热的第一导热件，所述安装基座安装于所述第一导热件上；
同时所述散热器上还设置有沿着该散热器的外周缘周向布置的第二导热件，所述第二导热件与所述第一导热件相抵接。
作为上述技术方案的改进，所述第二导热件由左导热件和右导热件拼接而成，所述左导热件和右导热件分别抵接于所述第一导热件的两侧。
作为上述技术方案的进一步改进，所述散热器的上部端面上还开设有用于安装所述第二导热件的嵌装槽，所述第二导热件安装于所述嵌装槽中。
其中，所述散热器上开设有沿其厚度方向布置的嵌装孔，所述第一导热件和/或第二导热件上设置有能够插入所述嵌装孔中的插入部。
优选地，所述第一导热件和第二导热件上均设置有能够插入所述嵌装孔中的插入部。
进一步，所述散热器上还设置有一用于反光的反光杯，所述反光杯位于所述安装基座和散热器之间，所述LED光源安装于所述安装基座朝向所述反光杯的一侧面上。
再进一步，所述反光杯的外周缘设置有能够搁置于所述散热器的上部端面处的延伸部，所述延伸部同时与所述第二导热件相抵接。
在本发明中，所述延伸部远离所述反光杯的一端处还设置有向下弯折且能够罩接于所述散热器外侧的折弯部。
在这里，所述第一导热件的外形呈“n”字形，所述第一导热件的两端与所述散热器相连接，而所述第一导热件的中部悬空，所述安装基座安装于所述第一散热件的中部悬空的位置处。
本发明的一优选实施例，所述第一导热件的中部与所述安装基座相接触的部分呈圆柱状，而第一导热件的两端呈扁平条状。
本发明的有益效果是：由于本发明的斗胆灯通过设置一沿着所述散热器的外周缘周向布置的第二导热件，同时该第二导热件与设置有安装基座的第一导热件相抵接，因此LED光源通电发光时产生的热量可以迅速传递给第一导热件，第一导热件再将热量传递给第二导热件，第二导热件则将热量迅速地沿着所述散热器的外周缘周向传递遍整个散热器，进而可以通过整个散热器进行散热，大大地加快了散热速度；
同时本发明的斗胆灯上还设置有一反光杯，同时该反光杯与所述第二导热件相抵接，因此第二导热件同时可以将热量传递给反光杯，进而该反光杯也可以进行散热，通过上述的结构，可以增大本发明的斗胆灯的散热面积，进而提升本发明的斗胆灯的散热性能。

具体实施方式
参照图1、图 2、图4、图6和图7，本发明的一优选实施例，一种斗胆灯，包括一散热器30，所述散热器30上设置有一用于导热的第一导热件41，所述第一导热件41上设置有一安装基座10，在本发明中，优选地，所述第一导热件41的外形呈“n”字形，所述第一导热件41的两端与所述散热器30相连接，而所述第一导热件41的中部悬空，所述安装基座10安装于所述第一散热件41的中部悬空的位置处，所述安装基座10上设置有一个以上的LED光源20，所述LED光源20的数量可以根据实际需要，可以设置一个、两个、三个或者多个，同时所述散热器30上还设置有沿着该散热器30的外周缘周向布置的第二导热件42，所述第二导热件42与所述第一导热件41相抵接，在这里，作为本发明的一优选实施例，所述第二导热件42设置于所述散热器30的上部端面上，为了使得LED光源20产生的热量可以更加迅速地传递给散热器30，在这里，进一步优选，所述第一导热件41和第二导热件42为超导热管。
因此LED光源20通电发光时产生的热量通过安装基座10可以迅速传递给第一导热件41，第一导热件41再将热量传递给与其相抵接的第二导热件42，由于第二导热件42沿着所述散热器30的外周缘周缘布置，因此第二导热件42可以迅速地将热量沿着所述散热器30的外周缘周向传递遍整个散热器30，进而热量可以通过整个散热器30进行散发至外界环境中去，大大地加快了散热速度。
参照图2和图6，在这里，为了便于本发明的斗胆灯的生产和安装，优选地，所述第二导热件42由左导热件421和右导热件422拼接而成，所述左导热件421和右导热件422分别抵接于所述第一导热件41的两侧，通过采用上述的结构，既便于第二导热件42的生产，同时也便于了本发明的斗胆灯的组装。
在本发明中，上述的第二导热件42也可以为一整体，然后只需在第二导热件42上开设供第一导热件41插入其内的即可。当然， 上述的第二导热件42和第一导热件41也可以为一体成型。
参照图3、图4和图5，为了便于第二导热件42上安装于所述散热器30上，在这里，所述散热器30的上部端面上还开设有用于安装所述第二导热件42的嵌装槽31，所述第二导热件42安装于所述嵌装槽31中。
为了使得第一导热件41和第二导热件42可以更好地传递遍整个散热器30，在这里，优选地，所述散热器30上开设有沿其厚度方向布置的嵌装孔32，所述第一导热件41和/或第二导热件42上设置有能够插入所述嵌装孔32中的插入部43。通过上述的结构，可以使得第一导热件41和第二导热件42的插入部43可以插入散热器30的内部，进而热量可以迅速地由散热器30的上部传递至散热器30的下部，提高了热传递的速度。
在本发明中，为了使得热量的传递更加迅速，所述第一导热件41和第二导热件42上均设置有能够插入所述嵌装孔32中的插入部43。因此通过第一导热件41和第二导热件42同时向所述散热器30传递热量，进而大大地加大了本发明的斗胆灯的传热速度。
参照图1、图2和图3，为了使得本发明的斗胆灯的光利用率更高，在这里，优选地，所述散热器30上还设置有一用于反光的反光杯50，所述反光杯50位于所述安装基座10和散热器30之间，所述LED光源20安装于所述安装基座10朝向所述反光杯50的一侧面上。通过反光杯50反射LED光源20的光线，避免光线向外散射，减少光损失。
在本发明中，所述反光杯50的外周缘设置有能够搁置于所述散热器30的上部端面处的延伸部51，所述延伸部51同时与所述第二导热件42相抵接。通过采用上述的结构，因此第二导热件42同时可以将热量传递给反光杯50，进而该反光杯50也可以进行散热，通过上述的结构，可以增大本发明的斗胆灯的散热面积，进而提升本发明的斗胆灯的散热性能。
在这里，为了使得反光杯50可以更好地安装固定于所述散热器30上，在本发明中，优选地，所述延伸部51远离所述反光杯50的一端处还设置有向下弯折且能够罩接于所述散热器30外侧的折弯部510。通过设置上述的折弯部510，可以便于反光杯50罩接于所述散热器30上，同时可以使得反光杯50与散热器30之间的连接更加紧密。
在这里，为了增强第一导热件41的导热效率，优选地，所述第一导热件41的中部与所述安装基座10相接触的部分呈圆柱状，而第一导热件41的两端呈扁平条状，通过将第一导热件41与安装基座10相接触的部分设置为圆柱状，可以增大第一导热件41与安装基座10的接触面积，进而提高热量的传递效率。
在本发明，上述的第一导热件41也制作成整条呈扁平条状，而不需要将第一导热件41的中部设置成圆柱状，当然上述的第一导热件41也可以制作成其他形状，如正六边形、椭圆形也是可以的，具体可以根据实际需要而定。
以上所述仅为本发明的优先实施方式，只要以基本相同手段实现本发明目的的技术方案都属于本发明的保护范围之内。
