Description
一种LED灯管
技术领域
[0001] 本实用新型涉及一种灯管结构，尤其是涉及一种灯罩由1/3铝合金外壳和2/3PC 罩结合构成的LED灯管结构。
背景技术
[0002] 随着LED的封装技术及光效的提高，LED应用照明领域得到广泛发展，LED灯管就是LED在照明领域中的应用。
[0003] LED灯管也俗称光管、日光灯管，其光源采用LED作为发光体，光效更高、更为节能、使用寿命更长，而且更为环保。LED灯管成为目前阶段代替荧光灯管的最理想产品，一般用于普通照明，写字楼，商场，酒楼，学校，家庭，工厂等室内照明。另外，LED灯管与传统的日光灯在外型尺寸口径上都一样，有T5管、T8管、TlO管的型号之分。
[0004] 但是，现有的LED灯管产品存在以下问题：
[0005] 1、电源在灯管内发热，散热不好灯管有光衰；
[0006] 2、电源寿命不高，且电源内置，更换不方便；
[0007] 3、灯罩的透光不均勻，侧边有发光暗区，发光面只占整个灯罩面积的约1/2，不能达到传统荧光灯360度出光的效果；透明罩灯管有发光网格暗区；
[0008] 4、灯管PC罩挤压有响声，双端高压供电，内置电源不能过安全认证；
[0009] 5、现有灯管灯珠采用3528、3014等型号，都是大电流，灯珠数量多，芯片温度较高，不能保证产品的寿命及光衰。
实用新型内容
[0010] 本实用新型提出一种LED灯管，通过外置电源、灯罩由1/3铝合金外壳和2/3PC罩结合构成来解决目前LED灯管存在散热不好、电源更换不便和灯罩透光不佳的技术问题。
[0011] 本实用新型采用如下技术方案实现：一种LED灯管，其包括：由铝合金的外壳和PC 罩连接构成的灯罩；设置在灯罩内部的铝基板，该铝基板上均勻分布设置若干个LED灯珠； 分别设置在灯罩两个末端的两个灯头，均通过螺钉锁合在灯罩上。
[0012] 其中，外壳的外表面积占灯罩外表面积的1/3，PC罩的外表面积占灯罩外表面积的 2/3。
[0013] 其中，外壳的外表面为圆弧形。
[0014] 其中，在外壳的两侧边之间连接设置固定板，在固定板上设置导热膜，而铝基板设置在导热膜之上。
[0015] 其中，在外壳的两侧边分别设置卡槽，而PC罩的两侧边分别设置嵌合在卡槽之中的固定块。
[0016] 其中，一个灯头上设置正极和负极，该正极、负极分别与外置的恒流驱动电源的正极、负极电性连接。在恒流驱动电源之中配置应急电源。
[0017] 与现有技术相比，本实用新型具有如下有益效果：[0018] 1、一方面，在铝基板与固定板之间设置导热膜，加速了 LED灯管内部热量向外壳传导，另一方面，外壳采用铝合金材质，且面积占整个灯罩面积1/3，保证了外壳与外界空气快速散热。
[0019] 2、由于PC罩的面积占整个灯罩面积2/3，因此，本实用新型提出的LED灯管发光面积占整个灯管外表面的2/3，比1/2灯罩出光更接近现有传统荧光管，具有发光均勻，且PC 罩为透明材质，灯管出光无网格暗区。
[0020] 3、外置的恒流驱动电源保证了电源更换方便，且恒流驱动电源配置应急电源，使本实用新型的LED灯管具应急功能。
[0021] 4、PC罩与铝合金紧配接合，手握挤压PC罩无响声；单端低压供电，外置电源，完全能过安全认证。
[0022] 5、LED灯珠采用5730灯珠，比3528灯珠、3014灯珠的发光面积大，从而可以减少
LED灯珠数量，并有效降低电流，更好的降低温度，保证产品寿命及光衰。
附图说明
[0023] 图1是本实用新型提出LED灯管的立体分解示意图；
[0024] 图2是LED灯管与电源的连接关系示意图。
具体实施方式
[0025] 如图1所示，本实用新型提出的LED灯管包括：灯罩，该灯罩由表面积占整个灯罩表面积1/3、材质为铝合金的外壳11和其表面积占整个灯罩表面积2/3、材质为PC (Polycarbonate，聚碳酸酯）的PC罩12结合构成的；设置在灯罩内部的铝基板13，该铝基板13上均勻分布设置若干个LED灯珠；分别设置在灯罩两个末端的灯头21和22，均通过螺钉锁合在灯罩上。
[0026] 其中，外壳11的外表面为圆弧，在外壳11的圆弧面两侧边之间连接设置固定板 111 ；固定板111上设置导热膜14，而铝基板13设置在导热膜14之上。另外，在外壳11的圆弧面两侧边设置卡槽112，而PC罩12的圆弧面两侧边设置固定块121，通过固定块121 嵌合在卡槽112使外壳11与PC罩12固定连接。
[0027] 工作时，铝基板13上的LED灯珠发光，热量依次通过铝基板13、导热膜14传导至固定板111，由固定板111传导至外壳11的圆弧面，通过外壳11的圆弧面与外界空气进行热交换完成散热。
[0028] 另外，由于LED灯珠按一定间距均勻排列设置在铝基板13上，LED灯珠发出的光亮通过PC罩12对外进行均勻扩散；且由于PC罩12的面积占整个灯罩面积2/3，因此，本实用新型提出的LED灯管发光面积占整个灯管外表面的2/3。
[0029] 结合图2所示，LED灯管的其中一个灯头21或22上设置正极和负极，该正极、负极分别与外置的恒流驱动电源的正极、负极电性连接。由外置的恒流驱动电源将供电电源 (一般为交流电)转换成低压直流，传送到灯头21或22为LED灯管供电。并且，恒流驱动电源配置应急电源，使本实用新型的LED灯管具应急功能。
[0030] 综上，本实用新型提出的LED灯管，与现有技术相比，具有如下有益技术效果：
[0031] 1、一方面，在铝基板与固定板之间设置导热膜，加速了 LED灯管内部热量向外壳传导，另一方面，外壳采用铝合金材质，且面积占整个灯罩面积1/3，保证了外壳与外界空气快速散热。
[0032] 2、由于PC罩的面积占整个灯罩面积2/3，因此，本实用新型提出的LED灯管发光面积占整个灯管外表面的2/3，具有发光均勻无暗区的特点。
[0033] 3、外置的恒流驱动电源保证了电源更换方便，且恒流驱动电源配置应急电源，使本实用新型的LED灯管具应急功能。
[0034] 以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
