Description

杆形 LED 技术领域
本发明涉及一种 LED, 具体涉及一种大功率螺杆形 LED。 背景技术
LED ( Light Emitting Diode) 是发光二极管的简称， 是一种固态的半导体器 件， 它可以直接把电转化为光。 LED光源具有使用低压电源、 耗能少、 适用性 强、 稳定性高、 响应时间短、 对环境无污染、 多色发光等的优点， 虽然价格较 现有照明器材昂贵， 但它仍被认为是将不可避免地替代现有照明器件。 目前大 功率 LED, 包括有 1W、 3W、 5W或更大功率类型， 它们在使用上都有一共同特 点， 就是大功率 LED必须先被固定到金属线路板如铝基板上， 然后将金属线路板 与散热外壳粘合，将大功率 LED工作时产生的热量散发出去，从而保证大功率 LED 的使用寿命， 这对散热外壳的散热结构要求非常高， 涉及的模具会非常昂贵， 而 且模具一旦定型， 无法更改， 不利于开发系列型的灯具。
目前由于能源紧张而促使许多国家包括中国都将节能摆到重要位置， 普通照 明用的白炽灯和卤钨灯虽价格便宜， 但光效低 （灯的热效应白白耗电）， 能耗 大， 寿命短， 维护工作量大， 这样， 以高能耗为特点的钨丝灯及卤素灯将很快被 淘汰， 而为这些灯泡设计的灯具也将面临淘汰， 造成很大的浪费， 这就需要一种 具有很好的兼容性、 能与这些灯具一起使用的 LED产品。 发明内容
本发明的目的是提供一种散热效果好、 使用方便、 可自由组合并能与普通灯 具结合使用的螺杆形 LED。
本发明的目的是通过如下技术方案来实现的： 包括大功率 LED、金属线路板、 电源线和螺杆形外壳， 所述的大功率 LED和金属线路板均设置在所述螺杆形外壳 内， 其中大功率 LED固定在金属线路板上并与金属线路板电连接， 电源线与金属 线路板电连接并且穿出所述的螺杆形外壳。
本发明螺杆形 LED工作时产生的热量通过螺杆形金属外壳向外散出， 螺杆形 设计既能增加散热面积， 又方便安装固定， 在需要安装 LED的位置根据螺杆形外 壳的规格开孔并制作螺纹， 安装孔的螺纹与螺杆形外壳的螺纹相匹配， 将螺杆形 LED直接拧进安装孔； 或在需要安装 LED的面板上根据螺杆外壳的尺寸开孔， 将 螺杆形 LED塞进安装孔，利用提供的配件将螺杆形 LED压紧在面板上， 即可完成 螺杆形 LED的安装。
作为木发明的一种实施方式， 所述的螺杆形外壳为具有外螺纹的筒形结构， 螺杆形外壳内部具有一端封闭、 另一端敞开的内腔， 所述的大功率 LED和金属线 路板均位于所述螺杆形外壳的内腔内。 外壳采用筒形结构方便生产加工， 当然也 可根据实际需要采用带有外螺纹的其它结构。
作为本发明的进一步改进， 还具有导热体， 所述的导热体位于所述螺杆形外 壳内， 其与螺杆形外壳的内壁相接触， 并且与所述的金属线路板相接触。 采用导 热体后， 大功率 LED工作时产生的热量通过导热体传递给螺杆形外壳， 螺杆形外 壳再将热量向外散出。
所述的导热体可以采用片状的导热结构， 导热体位于所述金属线路板和螺杆 形外壳的下底面之间， 并且分别与两者紧密接触， 通过紧密接触将大功率 LED工 作时产生的热量传递给螺杆形外壳散热。
所述的导热体还可以采用块状的导热结构 （如采用灌注的形式）， 只要其环围 所述金属线路板的周围， 并且在相对大功率 LED的区域留有空间即可。
通常导热体可选用具有良好导热作用的软硅胶材质， 也可采用其它导热效果 好的导热材料。
作为本发明的进一步改进， 还具有聚光透镜， 所述的聚光透镜安装在所述螺 杆形外壳的内腔的敞开端， 其位置与所述大功率 LED相适配， 聚光透镜可令大功 率 LED发出的光线产生聚光的作用。
上述螺杆形 LED适用于安装面板具有一定厚度的结构， 安装时， 直接在面板 上开设与螺杆形外壳相配合的螺纹孔， 然后将 LED通过螺杆形外壳旋进螺纹孔， 即可实现螺杆形 LED的安装定位。
作为本发明的更进一步改进： 还具有安装定位机构， 所述的安装定位机构与 螺杆形外壳螺纹连接， 所述的安装定位机构包括面盖和固定圈， 所述面盖的内壁 和固定圈的内壁分别具有与螺杆形外壳相配合的螺纹。
上述具有安装定位机构的螺杆形 LED适用于安装面板为薄板的结构， 通过面 盖和固定圈将螺杆形 LED安装固定在面板上。
与现有技术相比， 本发明螺杆形 LED的螺杆形设计能极大地增加散热面积， 其自身已解决了散热问题， 无须再考虑灯泡或灯具外壳的散热问题， 并且使用方 便，可根据需要将多个螺杆形 LED自由组合使用，给使用者提供很好的选择空间， 并且和现有的灯具具有很好的兼容性， 在安装过程中只需要拆下现有灯具的面盖， 然后再装上与原灯具面盖相适配、 且其上安装有一个或多个螺杆形 LED的面板， 再对螺杆形 LED进行电连接即可， 可以对如目前正在广泛使用的路灯、 隧道灯、 外墙灯等传统灯泡而设计的灯具实施改造， 节约能耗， 符合环保要求。 附图说明

图 12是本发明螺杆形 LED实施例四的安装示意图之二。 具体实施方式
实施例一
如图 1、 图 2所示的螺杆形 LED, 它包括大功率 LED 1、 金属线路板 2、 电源 线 3和螺杆形外壳 4， 螺杆形外壳 4为具有外螺纹的筒形结构， 螺杆形外壳 4内部 具有一端封闭、 另一端敞开的内腔， 大功率 LED 1和金属线路板 2均位于螺杆形 外壳 4的内腔内， 其中， 大功率 LED 1和电源线 3均焊接在金属线路板 2上并与 金属线路板 2电连接， 电源线 3并且穿出螺杆形外壳 4。
螺杆形 LED工作时产生的热量直接通过金属制成的螺杆形外壳 4向外散出， 螺杆形外壳 4能极大地增加散热面积， 所以螺杆形 LED自身已解决了散热问题， 无须再考虑灯泡或灯具外壳的散热问题， 同时螺杆形外壳 4又方便安装固定。 本实施例中的螺杆形外壳 4也可以采用其它形状的带外螺纹的合适结构。 实施例二
螺杆形 LED的实施例二如图 3、 图 4所示， 和实施例一不同的是， 它还具有 导热体 5， 导热体 5为片状的导热片结构， 导热体 5位于螺杆形外壳 4内， 其位于 金属线路板 2和螺杆形外壳 4的下底面之间， 并且分别与金属线路板 2和螺杆形 外壳 4的内壁相紧密接触。
导热体 5 采用具有良好导热效果的软硅胶材质， 也可以采用其它导热材料制 成， 大功率 LED 1工作时产生的热量通过导热体 5或其他散热材料迅速传导到螺 杆形外壳 4， 再通过螺杆形外壳 4向外散出。
本实施例中的导热体 5 也可以采用块状的导热结构 （如采用灌注软硅胶材料 的形式）， 其环围金属线路板 2的周围， 在相对大功率 LED 1的区域留有空间。 实施例三
螺杆形 LED的实施例三如图 5、 图 6所示， 和实施例二不同的是， 它还具有 聚光透镜 6， 聚光透镜 6安装在螺杆形外壳 4的内腔的敞开端， 其位置与大功率 LED 1相适配。 聚光透镜 6可插装在螺杆形外壳 4内， 两者也可采用螺纹连接， 聚光透镜 6可令大功率 LED 1发出的光线产生聚焦的作用，满足用户的使用要求。
本实施例的装配过程如下：将大功率 LED 1及电源线 3焊到金属线路板 2上， 再将金属线路板 2装进螺杆形外壳 4内， 电源线 3穿过螺杆形外壳 4， 金属线路板 2与螺杆形外壳 4之间通过绝缘导热体 5或其他导热材料连接，再装上聚光透镜 6， 这样就组合成如图 4的螺杆形 LED。
如图 7所示， 在需要安装螺杆形 LED的位置根据螺杆形外壳 4的尺寸及规格 开孔并制作螺纹，安装面板 9上的安装孔 9a的螺纹与螺杆形外壳 4的螺纹相匹配， 直接将螺杆形 LED拧进安装面板 9内。
如图 8所示，本实施例的螺杆形 LED可多个同时使用， 多个螺杆形 LED安装 在灯具面盖 10上组成螺杆形 LED灯具，由于螺杆形 LED自身已解决了散热问题， 这样能对目前为传统灯泡而设计的灯具实施改造， 如目前正在广泛使用的路灯、 隧道灯、 外墙灯等， 它们都使用高耗能的传统灯泡， 如果将灯泡及灯具整个换掉， 会造成材料的极大浪费， 也不环保， 而采用本实施例的螺杆形 LED, 只要求对原 有灯具的面盖进行更换， 根据原有灯具面盖的尺寸制作金属面板 10， 因为每个螺 杆形 LED都是标准件， 包括标准亮度， 这样可根据亮度的实际需要而在金属面板 10上根据螺杆形外壳 4的规格开孔并制作螺纹， 安装孔的螺纹与螺杆形外壳 4螺 纹相匹配， 将螺杆形 LED直接拧进安装孔， 这样就制成了 LED灯具面盖， 再对螺 杆形 LED进行电连接，然后将 LED灯具面盖固定到原有灯具的灯壳上，就制成了 LED灯具， 螺杆形 LED的热量更能通过金属面板 10向外界直接导出， 进一步增 加了大功率 LED的使用寿命及安全性。 实施例四
螺杆形 LED的实施例四如图 9、 图 10所示， 和实施例三不同的是， 它还具有 安装定位机构， 安装定位机构与螺杆形外壳 4 螺纹连接， 该安装定位机构包括面 盖 7和固定圈 8，面盖 7的内壁和固定圈 8的内壁分别具有与螺杆形外壳 4相配合 的螺纹。
本实施例的装配过程如下：将大功率 LED 1及电源线 3焊到金属线路板 2上， 再将金属线路板 2装进螺杆形外壳 4内， 电源线 3穿过螺杆形外壳 4， 金属线路板 2与螺杆形外壳 4之间通过绝缘导热体 5或其他导热材料连接， 装上聚光透镜 6， 再将面盖 7及固定圈 8拧进螺杆形外壳 4，这样就组合成如图 8的带面盖的大功率 螺杆形 LED。
本实施例同样也只要求对传统灯具的面盖进行更换， 根据原灯具面盖的尺寸 制作金属面板， 可根据亮度的实际需要而在金属面板上根据螺杆形外壳的规格开 孔 （开孔的数量与所需安装的螺杆形 LED的数量一致）， 如图 11所示， 在需要安 装螺杆形 LED的安装面板 9上开出安装孔 9a， 然后将螺杆形 LED直接塞进安装 孔 9a内， 如图 12所示， 再将固定圈 8拧进螺杆形外壳 4， 直到将带面盖 7的螺杆 形 LED压紧在安装板 9上， 就制成了 LED灯具面盖， 再对螺杆形 LED进行电连 接， 然后将该灯具面盖固定到原灯具的灯壳上， 就制成了 LED灯具； 螺杆形 LED 产生的热量更能通过金属面板 9向外界直接导出， 进一步增加了大功率 LED的使 用寿命及安全性。
总之， 本发明例举了上述优选实施方式， 但是应该说明， 本领域的技术人员 可以进行各种变化和改型。 因此， 除非这样的变化和改型偏离了本发明的范围， 否则都应该包括在本发明的保护范围内。
