Description
说明书 一种 LED灯管
技术领域
[1] 本发明涉及照明用灯具， 更具体地说， 涉及一种具有很好的散热效果的 LED灯 管。
背景技术
[2] 随着发光二极管 (Light Emitting
Diode, 简称 LED)光源的广泛应用， 现有的灯具大多使用 LED作为发光光源。 由 于 LED在将电能转换为光能的同吋， 不可避免的会产生一些热量， 功率越大、 亮 度越高， 则产生的热量越多。
[3] 如果热量不能及吋有效散发， 则过高的温度会影响电源的稳定， 加速 LED亮度 的衰减， 进而缩短 LED的使用寿命。 因此， 解决 LED灯具的散热问题十分重要。
[4] 而目前市场上的 LED灯管大多存在温度过高的问题， 限制了其亮度， 影响了灯 具的使用寿命， 并且现有的 LED灯管还存在外观粗糙的问题。 因此需要一种新的
LED灯管， 具有很好的散热效果。
发明内容
[5] 本发明要解决现有 LED灯管散热效果不够好的问题， 提供一种具有很好的散热 效果的 LED灯管。
[6] 本发明解决其技术问题所釆用的技术方案是， 构造一种 LED灯管， 包括管体、 装于管体内部的 LED安装板和驱动电源、 以及装于管体两端的端盖， 其中， 所述 管体由散热部件与透光罩扣合而成， 所述散热部件为长槽状、 且其横截面成弓 形， 所述 LED安装板与所述散热部件固定在一起。
[7] 本发明中， 最好在所述散热部件的内表面设有凹槽， 并将所述 LED安装板的边 缘插入在所述凹槽中与所述散热部件固定在一起。
[8] 本发明中， 所述透光罩最好为长槽状、 且其横截面成弓形。
[9] 本发明中， 最好在所述透光罩的内表面设有凸起， 所述散热部件的外表面设有 与所述凸起相匹配的卡槽， 所述透光罩上的凸起可卡入在所述散热部件上的卡
槽中， 与所述散热部件组合成所述管体。
[10] 本发明中， 所述管体最好为圆柱状结构。
[11] 本发明中， 所述驱动电源被固化在导热胶中， 所述导热胶紧贴散热部件的内壁
， 且所述被导热胶固化的驱动电源位于所述管体内部靠近端盖的位置。
[12] 本发明通过与 LED安装板固定在一起的散热部件， 将 LED安装板所发出的热量 散发出去， 同吋， 位于 LED灯管内部一端的驱动电源所发出的热量也可通过散热 部件进行散热， 由于散热部件的横截面成弓形， 散热面积大， 因此散热效果好 。 另外， 本发明通过相互匹配的凸起和卡槽将透光罩与散热部件组合成管体， 其组合方式十分方便， 组合后形成的管体外表面平滑。 本发明使用的驱动电源 被固化在导热胶中， 能起到绝缘、 阻燃和导热的作用， 增强了 LED灯管的安全性 和可靠性。

[14] 图 2是图 1中所示 LED灯管的放大分解示意图；
[15] 图 3是图 1中所示散热部件的截面图；
[16] 图 4是图 3中所示散热部件的立体图；
[17] 图 5是图 1中所示透光罩的截面图；
[18] 图 6是图 5中所示透光罩的立体图；
[19] 图 7是图 3中所示散热部件与图 5中所示透光罩扣合后的示意图；
[20] 图 8是图 2中所示端盖的立体图。
具体实施方式
[21] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 ， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[22] 本发明的一个优选实施例如图 1至图 8所示。 从图 1、 图 2中可以看出， 本实施例 中的 LED灯管包括 LED安装板 1、 散热部件 2、 透光罩 4、 端盖 7和驱动电源 8， LE D安装板 1为长条形， 位于 LED灯管内部， 其上设有多个 LED光源 9， LED安装板 1与驱动电源 8通过导线 10连接， 由驱动电源 8对 LED安装板 1上的 LED光源 9供电
。 散热部件 2和透光罩 4连接形成一个管体， 端盖 7位于管体的两端。
[23] 如图 3、 图 4和图 7所示， 散热部件 2整体成长槽状， 其横截面成弓形， 在散热部 件 2的内表面设有凹槽 3， LED安装板 1的边缘插入在凹槽 3中， 与散热部件 2固定 在一起。 在本实施例中， 散热部件 2可以是散热铝片， 这样， 由 LED安装板 1发出 的热量将通过散热部件 2传输出去， 由于散热部件 2的横截面成弓形， 散热的面 积大， 因此散热效果好。
[24] 如图 5、 图 6和图 7所示， 透光罩 4整体也成长槽状， 其横截面成弓形， 透光罩 4 的内表面设有凸起 5， 散热部件 2的外表面设有与凸起 5相匹配的卡槽 6， 透光罩 4 上的凸起 5卡入在散热部件 2的卡槽 6中， 与散热部件 2组合成管体， 这种组合十 分方便， 组合后形成的管体外表面平滑。 透光罩 4可以用耐高温、 抗紫外线的复 合 PC材料制成， 用于将 LED光源 9发出的光透射出去。
[25] 如图 8所示， 驱动电源 8中的各种器件可被浸入到导热胶中， 胶体干结后， 驱动 电源 8被固化在导热胶中， 导热胶再紧贴散热部件 2的内壁， 且被导热胶固化的 驱动电源 8位于管体内部靠近端盖 7的位置。
[26] 在 LED灯管中， 用于安装驱动电源的空间相对有限， 所以好的散热、 安全等设 计显得尤为重要。 本发明的方案对此有很好的改善， 其中使用的导热胶具有以 下两方面的作用：
[27] (1). 导热作用， 将驱动电源内的各器件中的热量传导到散热部件 2， 从而降低 器件温度， 延长器件寿命和产品寿命。
[28] (2)、 阻燃防护， 本实施例中使用的导热胶不能燃烧， 假如输入电压不当或其他 原因造成器件炸裂吋， 如果没有防护则有着火的危险， 有了该导热胶的防护， 则驱动电源内部不会着因此着火。 具体实施吋使用的导热胶要求能通过相关 UL 认证。
[29] (3)、 增强安规方面的电气性能， 更好地阻止电流爬电、 空间高压击穿的危害发 生， 使得产品更顺利地通过相关安规认证。
[30] (4)、 防止器件因外界原因而遭腐蚀、 带电， 从而防止人体触电， 该导热胶能阻 止空气和湿气与器件接触。
[31] (5)、 固定驱动电源， 防止线路短路和漏电， 防止人体被触电， 该导热胶将器件
、 PCB板固定于灯体内， 不因振动， 老化造成器件松动， 避免带电体接触灯具外
