Description

一种 LED灯泡 技术领域
本发明涉及的是灯具， 尤其是一种 LED灯泡。 背景技术
传统白炽灯通常耗电量大， 且温度高， 不利于节能。 随着 LED技 术的发展， 人们发现 LED是目前最好的照明光源之一， 它具有发光亮 度高、 使用寿命长等优点。但是 LED光源运行时的温度较高， 为改善 LED运行环境，通常都会将 LED贴在一散热器，利用散热器来散发 LED 运行中的热量。 现有以 LED 为光源的照明灯是一种直接照射结构的 LED灯泡， 这种 LED灯泡通常由一散热器、 粘贴在筒状散热器端面的 LED光源贴片、 安装在散热器另端的驱动器和灯头构成， 粘贴有 LED 光源贴片的散热器端安装在灯罩。这种结构的 LED灯泡由于 LED光源 和灯头安装在散热器的两端， 散热器通常具有一定的长度， 否则将达 不到 LED运行散热要求。受限于 LED运行散热要求， 目前 LED灯泡的 灯体通常较普通灯泡长， 尚无法做到与现有普通灯泡相同。这种灯体 较长的 LED灯泡不仅使用范围受到限制， 在现有灯具上安装时， 裸露 于灯罩外的灯泡光照直晃人眼， 会给人造成不适感， 且旋置在灯座上 的 LED灯泡之驱动器暴露在外， 显得既不协调、 又不美观。 发明内容
本发明所要解决的技术问题是弥补现有技术存在的缺陷，提供结 构紧凑、 长度与现有普通灯泡相当的 LED灯泡。
本发明通过以下方法得以解决。
这种 LED灯泡， 包括： 泡体、 散热器、 LED光源贴片、 与 LED光 源贴片电连接的驱动器及灯头。 这种 LED灯泡的特点是：
所述散热器为一端封闭的筒状散热器；
所述 LED光源贴片粘贴在筒状散热器的封闭端外端面； 所述与 LED光源贴片电连接的驱动器及灯头安装在筒状散热器封 闭端内端面。
本发明的技术问题通过以下进一步的技术方案予以解决。
所述筒状散热器可以是圆形筒、 方形筒或多边形筒状散热器。 所述筒状散热器由端盖和筒体构成， 端盖的外端面设有供 LED光 源贴片粘贴的平台。
所述筒状散热器的筒体由间隔排列的散热片围制而成。
围绕 LED光源贴片粘贴部位之筒状散热器端盖外端面设有供泡体 嵌入装配的环形槽。
所述筒状散热器端盖上设有散热孔。
所述筒状散热器端盖外端面还设有罩于 LED 光源贴片的导光透 镜。
所述筒状散热器为导热金属材料制成。
所述筒状散热器为铝质筒状散热器。
本发明 LED灯泡的设计原理是： 在不改变散热器长度及其散热面 积的前提下，将原本安装在散热器外端的驱动器及灯头安装到筒状散 热器内， 不仅可有效地縮短灯泡轴向长度， 实现与普通灯泡等长之发 明目的， 且丝毫不影响筒状散热器的散热功能。 在上述前提下， 这种 结构上的改进不仅可将原暴露在外的驱动器及灯头隐藏于筒状散热 器内， 使灯泡的外观得到完善， 且安装在筒状散热器内的灯头与筒状 散热器内壁之间形成的空间，恰好成为灯头与灯座旋拧连接配合的空 间， 当 LED灯泡旋置在灯座上时， LED灯泡的筒状散热器套罩在灯座 外， 可将灯座完全遮掩， 使 LED灯泡与灯座从外观视觉上形成一体， 达到装饰效果。
本发明的与现有技术对比的有益效果是：
这种 LED灯泡结构紧凑、 合理， 在确保其节能、 高光效、 长寿命 的基础上， 其外形可制成与现有普通灯泡完全相同， 能完全满足与现 有各种标准吊灯、水晶灯等灯具上的安装使用。且由于筒状散热器可 将灯头与灯座的连接部位完全遮掩， 使用更安全。
本发明的 LED灯泡具体结构由以下附图和实施例详细给出。 附图说明
图 1是本发明 LED灯泡实施例 1的示意图；
图 2是图 1所示 LED灯泡的分解结构示意图；
图 3是图 1所示 LED灯泡装配结构示意图；
图 4是本发明 LED灯泡实施例 2的示意图。 具体实施方式
实施例 1 : 从图 1和图 2可以清楚地看到 LED灯泡由泡体 1、 铝 质筒状散热器 2、 LED光源贴片 3、 导光透镜 4、 驱动器 5和灯头 6组 成。
所述筒状散热器 2为圆筒形结构， 由铝质端盖 21和铝质筒体 22 构成， 铝质端盖 21的外端面设有供 LED光源贴片 3粘贴的平台 23。 围绕 LED光源贴片 3粘贴部位之铝质端盖 21外端面设有供泡体 1口 端嵌入装配的环形槽 24， 铝质端盖 21上布有透气孔 （图中未示）。
所述 LED灯泡各部件的装配关系如下：
LED光源贴片 3粘贴在筒状散热器 2的铝质端盖 21外端面；铝质 端盖 21外端面还设有罩于 LED光源贴片 3上的导光透镜 4， 泡体 1 口端嵌入于铝质端盖 21的环形槽 24内， 形成 LED灯泡的发光头。
所述驱动器 5和灯头 6连为一体， 驱动器 5安装在筒状散热器 2 内之铝质端盖 21内端面。
所述驱动器 5与 LED光源贴片 3之间线连接。 实施例 2: 从图 4可以清楚地看到， LED灯泡的基本结构与实施 例 1完全相同， 区别仅为： 所述筒状散热器 2为圆筒形结构， 它由端 盖 21和铝质散热片围 25制而成的铝质透气筒体 26构成。
这种由铝质散热片 25围制而成的铝质透气筒体 26散热效果会更 佳。
以上内容是结合具体的优选实施方式对本发明所作的进一步详 细说明， 不能认定本发明的具体实施只局限于这些说明。对于本发明 所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下做 出若干等同替代或明显变型，而且性能或用途相同， 都应当视为属于 本发明由所提交的权利要求书确定的专利保护范围。
