Description

一种LED光源 技术领域
本实用新型属于LED技术领域，尤其涉及一种LED光源。
背景技术
电灯算是人类文明进程中最伟大和最重要的发明之一。其中，光源作为电灯中的重要组成部分，发展尤为迅速。从最早的白炽灯光源发展成时下最流行的LED光源，对于光源的性能和光传递效率的研究，越来越被看重。
现有技术中LED光源主要由灯罩、灯座、芯柱和灯芯组成，灯座内设置驱动电源，灯芯一般设置在导丝上，导丝固定在芯柱上，灯座除了起到支撑作用外，主要起散热作用，故又称散热座。现有技术中的灯芯通常包括发光芯片、金线和用于包覆发光芯片和金线的胶层，该金线用于连接发光芯片和驱动电源，灯芯通常采用灯珠的结构安装在导丝上。采用上述结构的光源，由于灯座和灯芯的设置，无法实现光源全角度覆盖，照明时存在一定的暗区，影响了光的传递效率。
发明内容
本实用新型的目的就是提供一种LED光源，可基本实现光源全角度覆盖，避免照明暗区，增加光的传递效率。
为了实现上述目的，本实用新型技术方案如下：
一种LED光源，包括灯罩、灯座、芯柱和灯芯，所述灯座内设置有驱动电源，所述芯柱上连有导丝，所述导丝包括4根连接柱，每根所述连接柱分别连接有1～2根灯条，所述均与呈对角设置的2根连接柱连接的灯条之间也互相连接，所述灯条包括由AB胶和荧光粉混合制成的包覆层、发光芯片和基板，所述发光芯片安装于基板，所述包覆层包覆发光芯片、基 板和连接柱。
所述相连的2根灯条与所述芯柱上端所在的平面形成的三角形面积相等。确保每根灯条倾斜的角度基本相同，使光源的光线照射得比较均匀。
所述灯条的上端点形成的面积大于等于所述灯条的下端点形成的面积。上端点形成的面积越大，光线的覆盖面积越大，可克服的灯座的暗区越大。
进一步地，所述连接于相同的2根连接柱且互相连接的灯条与所述灯座所在的纵向轴线之间的距离相同。保证每根灯条的角度基本相同，保证光线的均匀，避免暗区。
本实用新型的其中一种实施例，所述导丝包括4根连接柱，每根所述连接柱分别连接有1根灯条，所述与呈对角设置的2根连接柱连接的灯条之间互相连接。
本实用新型的另一种实施例，所述导丝包括4根连接柱，每根所述连接柱分别连接有2根灯条，所述均与呈对角设置的2根连接柱连接的灯条之间也互相连接。
本实用新型提出的LED光源，将灯芯设置成多个角度，即形成了多个角度的光源，使其交错设置，对任意一个方向均发射光线，避免了光照范围内的暗区，使光线较为均匀，实现光源的全角度覆盖，提高了光线的传递效率。
附图说明
图1为本实用新型的LED光源的结构示意图。
图中附图标记说明如下：1、灯罩，2、灯座，3、导丝，4、连接柱，5、灯条，6、芯柱。
具体实施方式
下面结合附图和实施例对本实用新型技术方案做进一步详细说明，以下实施例不构成对本实用新型的限定。
如图1所示，本实用新型的LED光源，包括灯罩1、灯座2、芯柱6 和灯芯，该灯座2内设置有驱动电源，用于驱动灯芯发光。芯柱6上安装有导丝3，导丝3包括4根连接柱4。在本实施例中，该导丝3包括4根连接柱4，连接柱4一端连接于芯柱6，另一端向上延伸，在芯柱6上端弯折形成相互对称且垂直的弯折部分，该4个弯折部分呈大致十字分布。
每根连接柱4在弯折部分可拆分，分成1～2根小连接柱4，每根小连接柱4与发光芯片和基板一起被由AB胶和荧光粉混合制成的包覆层包覆后就形成了可发光的灯条5，其中，发光芯片安装于基板。因此，换句话说，本实施例中，每根连接柱4在弯折部分拆分，可分别连接1～2根灯条5。
但是，需要强调的是，成对角设置的2根连接柱上必须是同时连接有相同数量的灯条5，也就是说，成对角设置的2根连接柱上要么同时连接有2根灯条5，要么同时连接有1根灯条5，不能出现呈对称设置的其中2根连接柱上连接了单独1根灯条5。再换句话说，整个导丝3分出来的4根连接柱4上总的灯条5数量是在4～8之间的偶数根，即4根，6根和8根。另外，导丝3的数量，即连接柱4的数量，也可以减少，为2根，其中2根时，灯条5的数量也是偶数根，为2根或4根灯条。
值得注意的是，同时与呈对角设置的2根连接柱4连接灯条5之间也互相连接。
举例一如下：
将连接柱4命名为A、B、C和D，其中，A和C呈对角设置，B和D呈对角设置。
A上连接有1根灯条a，C上也连接有1根灯条c，则a和c也互相连接；B上连接有2根灯条b1和b2，D上连接有2根灯条d1和d2，则b1和d1也互相连接，b2和d2也互相连接。
举例二如下：
将连接柱4命名为A、B、C和D，其中，A和C呈对角设置，B和D呈对角设置。
A上连接有2根灯条a1和a2，C上也连接有2根灯条c1和c2，则a1和c1也互相连接，a2和c2也互相连接；B上连接有2根灯条b1和b2，D 上连接有2根灯条d1和d2，则b1和d1也互相连接，b2和d2也互相连接。
举例三如下：
将连接柱4命名为A、B、C和D，其中，A和C呈对角设置，B和D呈对角设置。
A上连接有1根灯条a，C上也连接有1根灯条c，则a和c也互相连接；B上连接有1根灯条b，D上连接有1根灯条d，则b和d也互相连接。
其中，相连的2根灯条5与所述芯柱6上端所在的平面形成的三角形面积相等。
相对于上述例子来解释，在例一中，a和c与芯柱6上端所在的平面形成的三角形面积S1、b1和d1与芯柱6上端所在的平面形成的三角形面积S2以及b2和d2与芯柱6上端所在的平面形成的三角形面积S3相同。
在例二中，a1和c1与芯柱6上端所在的平面形成的三角形面积S4、a2和c2与芯柱6上端所在的平面形成的三角形面积S5、b1和d1与芯柱6上端所在的平面形成的三角形面积S6以及b2和d2与芯柱6上端所在的平面形成的三角形面积S7相同。
在例三中，a和c与芯柱6上端所在的平面形成的三角形面积S8以及b和d与芯柱6上端所在的平面形成的三角形面积S9相同。
因为呈对角的2根连接柱4之间的距离是相同的，所以相连的2根灯条5与芯柱6上端所在的平面形成的三角形面积相等，即相连的2根连接柱4的连接点与芯柱6所在的平面的高度是相同的。
灯条5的上端点形成的面积大于等于所述灯条5的下端点形成的面积。连接于相同的2根连接柱4且互相连接的灯条5与所述灯座2所在的纵向轴线之间的距离相同。
在上述例一种，a和c的连接点与灯座2所在的纵向轴线之间的距离H1、b1和d1的连接点与灯座2所在的纵向轴线之间的距离H2以及b2和d2的连接点与灯座2所在的纵向轴线之间的距离H3相等。
在例二中，a1和c1连接点与灯座2所在的纵向轴线之间的距离H4、a2和c2连接点与灯座2所在的纵向轴线之间的距离H5、b1和d1连接点 与灯座2所在的纵向轴线之间的距离H6以及b2和d2连接点与灯座2所在的纵向轴线之间的距离H7相等。
在例三中，a和c连接点与灯座2所在的纵向轴线之间的距离H8以及b和d连接点与灯座2所在的纵向轴线之间的距离H9相等。
以上实施例仅用以说明本发明的技术方案而非对其进行限制，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
