Abstract

本发明公开了一种带散热孔的灯泡，在灯座壳体和/或导光灯罩表面设有相应连通其内腔与外界的散热孔，空气通过散热孔则流进/出灯座壳体和导光灯罩内腔，故灯泡发光工作时，其所产生的热量，则可以由散热孔散出外界，使得灯泡内部的热量得到有效散去，同时提高了灯泡的使用寿命，具有结构简单、实用的特点。

Description

带散热孔的灯泡
【技术领域】
本发明涉及照明灯具，尤其是一种带散热孔的灯泡。
【背景技术】
现有技术中，灯泡其外形结构上都没有设有专用于其散热的结构，特别是当前普及使用的LED灯，LED灯珠设在相应的驱动电路板上，工作时，将产生大量的热量，若该热量得不到有效的及时散去，使用时间长后，将影响LED灯的使用寿命。
本发明即针对上述问题而研究提出。
【发明内容】
本发明要解决的技术问题是提供一种带散热孔的灯泡，在灯座壳体和/或导光灯罩表面设有相应连通其内腔与外界的散热孔，空气通过散热孔则流进/出灯座壳体和导光灯罩内腔，故灯泡发光工作时，其所产生的热量，则可以由散热孔散出外界，使得灯泡内部的热量得到有效散去，同时提高了灯泡的使用寿命，具有结构简单、实用的特点。
为解决上述技术问题，本发明带散热孔的灯泡，包括灯座壳体，所述灯座壳体上设有发光光源组件，所述灯座壳体上还设有用于罩住发光光源组件的导光灯罩，其特征在于所述灯座壳体和/或导光灯罩表面设有相应连通其内腔与外界的散热孔。
所述散热孔为圆孔、椭圆孔或多边形孔。
所述导光灯罩表面设有至少两种或两种以上不同形状的散热孔。
所述灯座壳体与导光灯罩之间卡接或通过螺牙连接。
所述灯座壳体与导光灯罩连接处设有隔热层或隔热片/垫。
所述导光灯罩内侧壁设有隔热层。
与现有技术相比较，本发明设在灯座壳体和/或导光灯罩表面散热孔，散热孔与散热孔之间则形成相应的空气对流，故灯泡发光工作时，其所产生的热量，则被其内腔流动的空气及时散出外界，使得灯泡内部的热量得到有效散去，同时提高了灯泡的使用寿命，具有结构简单、实用的特点。
【附图说明】
下面结合附图对本发明的具体实施方式作进一步详细说明，其中：
图1为本发明第一种实施例的立体结构示意图。
图2为图1的爆炸视图。
图3为本发明第二种实施例的立体结构示意图。
图4为本发明第二种实施例的立体结构示意图。
图5为本发明第三级种实施例的立体结构示意图。
图6为本发明第四种实施例的立体结构示意图。
图7为本发明第五种实施例的立体结构示意图。
【具体实施方式】
下面结合附图对本发明的实施方式作详细说明。
如图1-7所示，本发明带散热孔的灯泡，包括灯座壳体1，所述灯座壳体1上设有发光光源组件2，发光光源组件2包括控制电路板 21和设在控制电路板21上的LED灯珠22，所述灯座壳体1上还设有用于罩住发光光源组件2的导光灯罩3，其特征在于所述灯座壳体1和/或导光灯罩3表面设有相应连通其内腔与外界的散热孔4。由于散热孔4与灯座壳体1及导光灯罩3的内腔连通，灯泡周遭的空气通过散热孔4形成经过灯座壳体1及导光灯罩3的内腔对流，进而可及时将灯泡内的热量散去，具有结构简单及实用的特点。
如图1、图3-7所示，根据设计需要，所述散热孔4为圆孔、椭圆孔或多边形孔，所述多边形空包括三角形孔、四边形孔、星形孔等。另外，所述散热孔4采用统一的大小或采用不同大小。
同样地，所述导光灯罩3和/或灯座壳体1表面设有至少两种或两种以上不同形状的散热孔4。
所述灯座壳体1与导光灯罩3之间卡接或通过螺牙连接。如图2 所示，所述灯座壳体1与导光灯罩3之间通过螺牙连接。
为进一步保证灯泡的使用寿命，在所述灯座壳体1与导光灯罩3 连接处设有隔热层或隔热片/垫；以及根据需要，在所述导光灯罩3 内侧壁设有隔热层，本发明中，所述隔热层为石棉涂层，也可以为其它具有隔热效果的涂层；所述隔热片/垫由石棉材料制成的片/垫，或由其他具有隔热效果的材料制成。
