Abstract

一种符合安全标准的通用型双端LED灯管及其模组，符合安全标准的通用型双端LED灯管模组由第一模块（I）以及第二模块（II）组成，该LED模组包括：高频变压器TB、电容、高频扼流电感、双向可控硅、整流桥、继电器、高频驱动器（203）和低频驱动器（204）。该技术方案具有通用型强，安全性高的优点。

Description

符合安全标准的通用型双端LED灯管及其模组 技术领域
本发明涉及LED领域，尤其涉及一种符合安全标准的通用型双端LED灯管及其模组。
 背景技术
采用LED灯管直接替换传统荧光灯照明灯具上的荧光灯管，可取得节能减排，提高光效、改善光环境、降低改造成本的显著效果。
但由于传统荧光灯具上的镇流器通常有电感镇流器或电子镇流器两类，两者的工作原理，电路接线方式和输出电压，电流完全不同，特别是输出电压，电流的频率更是差异巨大，一般电感镇流器输出的电压，电流为50/60Hz的工频，而电子镇流器则输出25KHz-80KHz的高频电压、电流。
根据传统荧光灯具上的镇流器不同，现有设计和制造的LED灯管分别采用电感兼容型或电子兼容型两种不同的技术方案。
由于双端LED灯管在安装时，无法保证两端同时装入灯具灯座内，因而存在触电隐患，为此IEC62776标准明确规定灯管两端必须存在爬电距离（≥2.5mm）和电气间隙（≥1.5mm），从而使灯管两端有效电隔离。
而在实际的直接替换操作中，除专业电工外，用户很难区分电子或电感这二者之间的差别和安全操作规程，如不慎混用或违规操作，轻则导致LED灯管损毁，重则引起火灾和人身安全事故。
由于现有LED灯管缺乏通用型和安全性，无法成为流通商品，因此极大地制约了他的节能改造的应用领域和推广普及速度和范围。

[根据细则91更正 25.12.2017]　
对于工频信号来说，其通过L4、L5与低频驱动器连接LED灯206，此时2端即第二金属灯脚悬空，对于3、4端即第三、第四金属灯脚来说由于其不通电，第一、二金属灯脚的电压无法传递到第三、第四金属灯脚，所以第三、第四金属灯脚符合IEC62776标准的安全性规定，当第三、第四金属灯脚和第一、二均插入时，可以通过如图5a所示的管型保险SFS将第三、四灯脚的N线接入到第二灯脚，从而实现工频的导通。
对于高频信号来说，其通过C1、C2与高频驱动器连接LED灯206，此时如果第三、四金属灯脚不接电，该继电器的开关JK1和JK2不会吸合闭合，这样，开关JK1和JK2形成的隔离足够符合ICE62776标准的安全性规定，当第三、四金属灯脚与第一、二金属灯脚同时插入时，继电器工作，吸合JK1和JK2，从而实现高频驱动器导通对LED灯206供电。
