Description

LED灯泡形灯
技术领域
本实用新型属于照明设备技术领域， 尤其涉及一种 LED灯泡形灯，可代替传统照明用 灯泡。 背景技术
现有技术的 LED灯泡形灯， 将 LED灯板组件安装于散热体的一端， 并在此散热体的 一端覆盖所述灯板组件并安装灯罩， 而且在此散热体的另一端安装着灯头壳， 在散热体与 灯头壳之间安装着亮灯电路。
对于此种灯泡形灯而言， 从 LED元件所产生的热量会引起 LED灯泡形灯整体的温度 上升，从而引起 LED灯泡形灯的光输出下降且寿命缩短， 所以要求能抑制 LED温度上升， 为此， 釆用通过散热性优异的材料以及成型凸凹表面来形成散热体的方法等。
然而， 在具备灯罩的灯泡形灯中， 因为 LED被灯罩覆盖着， 所以存在着以下问题： LED的散热效率差， 即便使用金属制的散热体也无法充分的抑制 LED灯泡形灯的温度上 升。
另夕卜，现有技术的 LED照明灯具的散热部分利用实体金属车加工技术制成，存在制造 成本过高、 重量增大的问题， 并且批量生产产量不高， 对材料的利用率也有限， 从而提 高了灯具本身的开发和材料成本， 最终增大了消费者的消费负担， 同样的， 如果此 LED照 明灯具的重量较大，那么施加于使用此 LED照明灯具的负荷也变大， 因此必须解决提高照 明器具的支撑强度的问题。
由此可见， 上述现有的 LED灯泡形灯在结构与使用上， 显然仍存在有不便与缺陷，需 要进一步改进。 为了解决上述存在的问题， 相关厂商莫不费尽心思来谋求解决之道， 但长 久以来一直未见使用行之有效的解决方法， 严重阻碍着行业的发展。 因此如何能设计一种 新型结构的 LED灯泡形灯，实属当前重要研发课题之一，亦成为当前行业急需改进的目标。
为克服以上传统 LED灯散热灯体结构的不足，工程师们经过长期的探索和测试，开发 出新结构的 LED灯， 使其散热性能得到明显改善， 大大的提高了其使用性和寿命， 同时也 降低开发和材料的成本。 发明内容
为克服传统 LED灯体结构上的不足，本实用新型的目的在于提供一种 LED灯泡形灯， 釆用开放式散热模式， 改善了散热结构上的不足。 本实用新型是通过以下技术方案来实现的：
LED灯泡形灯， 包括有： 壳体部件、 LED电路部件以及亮灯电路部件， 所述壳体部件 包括有灯体和灯头， LED电路部件以及亮灯电路部件位于壳体部件的内部空腔中； 所述 LED电路部件包括有基板和安装在基板正面上的 LED发光元件； 其中， 所述灯体为釆用 散热材料压制加工制成的散热体， 下端与灯头连接， 上端设置有 LED电路部件连接部；所 述基板的背面与所述散热体的 LED电路部件连接部釆用充分导热的方式面接触式连接；所 述散热体的 LED电路部件连接部与散热体的主体为一整体结构件；所述壳体部件的外壁面 上设置有两组以上的散热孔组合， 壳体部件的内部空腔设置有散热气流通道， 两组以上的 散热孔组合分别形成进气孔组合和排气孔组合； 进气孔组合和排气孔组合均与散热气流通 道连通。
本实用新型的有益效果如下：
本实用新型的 LED灯泡形灯， 由于灯体为釆用散热材料压制加工制成的散热体， 壳体 部件的外壁面上设置有两组以上的散热孔组合， 壳体部件的内部空腔设置有散热气流通 道， 两组以上的散热孔组合分别形成进气孔组合和排气孔组合； 进气孔组合和排气孔组合 均与散热气流通道连通。 两组以上的散热孔组合之间没有大的障碍部件， 从而确保形成顺 畅的空气流动通道， 当 LED灯泡形灯及散热部件在工作状态， 因发热温度升高时， LED 灯泡形灯及散热部件内外表面均可形成冷热空气对流，从而增加 LED灯泡形灯及散热部件 的散热表面积，保证 LED灯泡形灯及散热部件良好的散热方式。釆用内外空气对流散热结 构， 增加了散热表面积， 无论从散热成本， 从散热效益上都有很大的提高， 克服长期照明 用 LED灯的散热难题， 在照明用 LED灯散热结构技术上是一次全新的实用创新。
本实用新型的 LED灯泡形灯， 其优点是：
1、 在结构上， 在结构部件上一个或多个部位设置通风孔， 内部设置足够的空气间隙， 产品受热时内部空气能够顺畅的对流， 取代传统的大面积（散热翅片或异形表面）传导散 热的方式， 同时也减少了散热部分的材料用量， 很大程度上既节省了原材料成本， 减轻了 产品本身的重量。
2、 在产品使用过程中， 由于 LED的使发热产品温度升高时， 除了产品外部表面常规 散热外， 产品内部也能够充分的散热， 从而提高产品效率， 延长产品寿命。
