Description

LED 灯泡
技术领域
本实用新型涉及一种照明灯具，特别是涉及一种 LED 灯泡。
背景技术
现有的 LED 灯泡通常是由灯头、灯座、散热器、 LED 光源、 LED 电源和灯罩组成，其中， LED 光源安装在金属散热器的顶部，金属散热器的外周包裹有塑胶灯座以起绝缘作用，金属散热器和灯罩安装在塑胶灯座上，塑胶灯座安装在灯头上。然而，由于散热器和灯座的设置，导致 LED 灯泡存在结构复杂、结构体积大的缺陷，而且受灯座结构的限定，灯罩通常为半球形结构，其发光面积小，导致 LED 灯泡的光照效果不理想。
实用新型内容
基于此，有必要针对现有 LED 灯泡所存在的问题，提供一种结构简单、散热效果好且发光面积大的 LED 灯泡。
一种 LED 灯泡，包括灯头、 LED 电源、 LED 光源、导热器和灯罩，其中，所述的导热器过盈配合安装在所述灯头内，所述的 LED 光源安装在所述导热器上，所述的 LED 电源分别与所述 LED 光源和灯头电连接，所述的灯罩固定连接于所述灯头上。
在其中一个实施例中，所述的导热器具有纵向多边形结构或圆柱形结构，所述导热器的各个侧面上均安装有所述 LED 光源。
在其中一个实施例中，所述导热器的顶部还安装有所述 LED 光源。
在其中一个实施例中，所述的 LED 光源包括线路板以及安装在所述线路板上的 LED 灯珠，所述的线路板分别与所述 LED 灯珠和 LED 电源电连接。
在其中一个实施例中，所述 LED 光源的线路板为柔性线路板或者铝基线路板。
在其中一个实施例中，所述的 LED 光源通过导热硅胶贴合在所述导热器上或者通过螺丝固定安装在所述导热器上。
在其中一个实施例中，所述的导热器为中空结构，所述的 LED 电源安装在所述导热器的内腔中。
在其中一个实施例中，所述的导热器为金属导热器、导热塑料导热器、陶瓷导热器或者玻璃导热器。
在其中一个实施例中，所述导热器与所述灯头的连接处填充有导热硅胶。

本实用新型所述的 LED 灯泡具有以下优点：
1 、 LED 光源安装在导热器上，导热器过盈配合安装在灯头内，并且灯罩直接连接在灯头上，而灯头、灯罩均与空气接触，这使得 LED 光源工作时所产生的热量可通过导热器传导到灯头、灯罩上，灯头和灯罩以对流与辐射的方式将热量传导到空气中进行散热，导热器同时亦通过辐射的方式进行散热，由此可达到良好的散热、降温效果，可延长 LED 灯珠的使用寿命。
2 、灯罩直接固定连接在灯头上， LED 电源、 LED 光源和导热器均置于灯头和灯罩内，能够节省 LED 灯泡的体积，简化 LED 灯泡的结构，并且能够增大灯罩的表面积，从而扩大 LED 灯泡的发光角度（可达 320 ° ），增大 LED 灯泡的光照面积，提高 LED 灯泡的光照效果，同时亦避免了散热器等金属部件外露造成的安全隐患。
3 、导热器具有纵向多边形结构，可在导热器的各个侧面及其顶部可安装多个 LED 光源，由此可增大 LED 灯泡的光照面积，提高 LED 灯泡的光照强度，而由于侧面上的 LED 光源与导热器的侧面直接贴合， LED 光源所产生的热量能够有效地传导到导热器上进行散热降温，由此可解决多个 LED 光源同时工作所造成的热量问题。

如图 1 至图 3 所示，本实用新型所述的 LED 灯泡包括灯头 1 、 LED 电源 2 、 LED 光源 3 、导热器 4 和灯罩 5 。
导热器 4 为金属导热器、导热塑料导热器、陶瓷导热器或玻璃导热器；导热器 4 的上部呈圆柱形或者呈纵向多边形（包括四边形、五边形、六边形、七边形和八边形等），下部呈圆柱形，且为中空结构。
导热器 4 过盈配合安装在灯头 1 内，导热器 4 与灯头 1 的连接处填充有导热硅胶； LED 光源 3 安装在导热器 4 的侧部和顶部； LED 电源 2 安装在导热器 4 的内腔中，并分别与 LED 光源 3 和灯头 1 电连接；灯罩 5 通过胶水粘合固定连接在灯头 1 上。
LED 光源 3 包括柔性线路板 32 和安装在柔性线路板 32 上的 LED 灯珠 31 ，柔性线路板 32 分别与 LED 灯珠 31 和 LED 电源 2 电连接。柔性线路板 32 通过折叠包覆在导热器 4 的侧面和顶部，并通过导热硅胶贴合在导热器 4 上，从而使 LED 灯珠 31 分布在导热器 4 的侧面和顶部。
灯罩 5 为玻璃灯罩或者导热塑料灯罩，其形状可以是球形或烛形等。
由于灯罩 5 直接固定连接在灯头 1 上，且 LED 电源 2 、 LED 光源 3 和导热器 4 均置于灯头 1 和灯罩 5 内，由此简化了 LED 灯泡的结构，缩小了 LED 灯泡的整体体积，并且使灯罩 5 的表面积增大，从而增大 LED 灯泡的光照面积，提高 LED 灯泡的光照效果，同时亦避免了金属部件外露造成的安全隐患。
导热器 4 具有纵向多边形结构，其各个侧面和顶部均分布有 LED 灯珠 31 ，由此使得 LED 灯泡的各个方向上均具有 LED 灯珠进行发光，从而增大了 LED 灯泡的光照面积，提高了 LED 灯泡的光照强度。
LED 光源 3 通过其柔性线路板 32 贴合在导热器 4 的侧面和顶部，而导热器 4 过盈配合安装在灯头 1 内，且灯罩 5 直接连接在灯头 1 上，这使得 LED 灯珠 31 工作时所产生的热量可通过柔性线路板 32 传导到导热器 4 上，导热器 4 一方面通过辐射的方式进行散热，另一方面亦将热量传导到灯头 1 和灯罩 5 上，由于灯头 1 、灯罩 5 均与空气接触，可以对流与辐射的方式将热量传导到空气中进行散热，由此达到良好的散热、降温效果，可延长 LED 灯珠 31 的使用寿命。
实施例二：
如图 4 至图 6 所示，本实用新型所述的 LED 灯泡包括灯头 1 、 LED 电源 2 、 LED 光源 3 、导热器 4 和灯罩 5 。
导热器 4 为金属导热器、导热塑料导热器、陶瓷导热器或玻璃导热器；导热器 4 呈纵向多边形（包括四边形、五边形、六边形、七边形和八边形等），且为中空结构。

第一 LED 光源 33 包括柔性线路板 35 以及安装在柔性线路板 35 上的 LED 灯珠 31 ，柔性线路板 35 分别与 LED 灯珠 31 和 LED 电源 2 电连接。柔性线路板 35 通过导热硅胶贴合在导热器 4 的侧面上，从而将第一 LED 光源 33 安装在导热器 4 的侧面上。第二 LED 光源 34 包括铝基线路板 36 以及安装在铝基线路板 36 上的 LED 灯珠 31 ，铝基线路板 36 分别与 LED 灯珠 31 和 LED 电源 2 电连接。铝基线路板 36 通过螺丝固定安装在导热器 4 的顶部，从而将第二 LED 光源 34 安装在导热器 4 的顶部。
灯罩 5 为玻璃灯罩或者导热塑料灯罩，其形状可以是球形或烛形等。
由于灯罩 5 直接固定连接在灯头 1 上，且 LED 电源 2 、 LED 光源 3 和导热器 4 均置于灯头 1 和灯罩 5 内，由此简化了 LED 灯泡的结构，缩小了 LED 灯泡的整体体积，并且使灯罩 5 的表面积增大，从而增大 LED 灯泡的光照面积，提高 LED 灯泡的光照效果，同时亦避免了金属部件外露造成的安全隐患。
导热器 4 具有纵向多边形结构，其各个侧面上均安装有第一 LED 光源 33 ，且其顶部还安装有第二 LED 光源 34 ，由此使得 LED 灯泡的各个方向上均具有 LED 灯珠进行发光，从而增大了 LED 灯泡的光照面积，提高了 LED 灯泡的光照强度。
第一 LED 光源 33 、第二 LED 光源 34 分别贴合在导热器 4 的侧面和顶部，而导热器 4 过盈配合安装在灯头 1 内，且灯罩 5 直接连接在灯头 1 上，这使得 LED 灯珠 31 工作时所产生的热量可通过线路板 35 、 36 传导到导热器 4 上，导热器 4 一方面通过辐射的方式进行散热，另一方面亦将热量传导到灯头 1 和灯罩 5 上，由于灯头 1 、灯罩 5 均与空气接触，可以对流与辐射的方式将热量传导到空气中进行散热，由此达到良好的散热、降温效果，可延长 LED 灯珠 31 的使用寿命。
