本发明涉及灯管，更具体地说，涉及一种可换电源灯管。
背景技术
目前常规LED日光灯管大部分AC/DC电源模块为灯管内置结构，由于内部电源放置的空间紧凑，布线难度高，不便于用户日后的维护，必须由厂家处理，技术人员安装。由此，使得用户维护成本高，时效性较差。因此，需要开发一种方便拆卸、方便维护和方便升级的日光灯管。
发明内容
本发明要解决的技术问题在于，针对现有技术的LED日光灯管维护成本高，时效性较差等缺陷，提供一种可换电源灯管。

附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是本发明可换电源灯管第一实施例的结构示意图；
图2是本发明可换电源灯管第二实施例的结构示意图；
图3是本发明可换电源灯管的电路原理图。
具体实施方式
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。
如图1所示，在本发明可换电源灯管的第一实施例中，其主要承载部件为壳体，该壳体由金属外壳2和透明灯罩1拼装而成，在具体设计时，金属外壳2主要是由铝合金材料制成，透明灯罩1由PC（聚碳酸酯）材料制成，其具体可以是透明罩，在该透明罩上可添加条纹等装饰件。在实际使用中，在透明灯罩1内设置有LED灯条（图中未示出），且该LED灯条安装在金属外壳2上。
本发明的创新点在于，将电源模块3可拆卸地设置在壳体的外部，如图1所示的实施例中，在金属外壳2上设置有电源安装槽7，电源模块3可拆卸地插装在电源安装槽7内，在电源模块3的左右两侧分别设置有电源输入插件31和直流电源输出插件32，该电源输入插件31作为与外部供电电源连接，进行供电的接口，而直流电源输出插件32作为该电源模块3将输入的供电电源进行变换后输出的直流电源的接口，为该灯管进行供电。在本发明中，可适用的外部供电电源为85V~270V之间。由此，电源模块3可以从灯管外直接取下和安装，以方便用户后期维护。同时还便于灯管的升级，即随着产品功能的不断升级，用户可以在原灯管的基础上，只需更换电源模块就可以实现功能方面的改进。在具体设计时，该电源输入插件31可以是交流电源输入插件或者是直流电源输入插件。
为了便于电源模块3可正确无误地插装到电源安装槽7内，如图1所示，在电源安装槽7的内壁上设置有与电源输入插件31相匹配的电源输入接插件34，及与直流电源输出插件32相匹配的直流电源输出接插件33，从而在安装电源模块3时，仅当电源输入插件31与电源输入接插件34对接及直流电源输出插件32与直流电源输出接插件33对接后，才能将电源模块7正确地插装在电源安装槽7内。由此可根据不同电参数规格的灯管，配有不同的接插件防止用户误用，更换电源的操作，用户能轻松完成。其中，对于不同长度及规格的灯管，不同的灯管之间可以具有相同的电源输入插件31和电源输入接插件34，而不同的灯管之间的直流电源输出插件32和直流电源输出接插件33则不同。
为了便于将整个日光灯管的固定，在壳体的两侧分别设置有针脚组件。每个针脚组件包括两个针脚4，其中，一个针脚设置在金属外壳2上，另一个针脚设置在透明灯罩1上。
如图2所示，在本发明可换电源灯管的第二实施例中，该壳体由左右两侧的两个端盖8及位于两个端盖8之间的塑胶外壳21、金属外壳22和灯罩1拼装而成，其中，塑胶外壳21位于金属外壳22的顶部，灯罩1位于金属外壳22的底部。在具体设计时，金属外壳22主要是由铝合金材料制成，灯罩1可以是具有高透光率的非透明PC（聚碳酸酯）灯罩或透明PC灯罩制成。例如，透明的灯罩1由PC（聚碳酸酯）材料制成，其具体可以是透明罩，在该透明罩上可添加条纹等装饰件。在实际使用中，在透明的灯罩1内设置有LED灯条（图中未示出），且该LED灯条安装在金属外壳22上。
同样，在图2所示的第二实施例中，将电源模块3可拆卸地设置在壳体的外部，在塑胶外壳21上设置有电源安装槽7，电源模块3可拆卸地插装在电源安装槽7内，在电源模块3的左右两侧分别设置有电源输入插件31和直流电源输出插件32，该电源输入接插件31作为与外部供电电源连接，进行供电的接口，而直流电源输出插件32作为该电源模块3将输入的供电电源进行变换后输出的直流电源的接口，为该灯管进行供电。在本发明中，可适用的外部供电电源为85V~270V之间。由此，电源模块3可以从灯管外直接取下和安装，以方便用户后期维护。同时还便于灯管的升级，即随着产品功能的不断升级，用户可以在原灯管的基础上，只需更换电源模块就可以实现功能方面的改进。
在电源安装槽7的内壁上设置有与电源输入插件31相匹配的电源输入接插件34，及与直流电源输出插件32相匹配的直流电源输出接插件33，从而在安装电源模块3时，仅当电源输入插件31与电源输入接插件34对接及直流电源输出插件32与直流电源输出接插件33对接后，才能将电源模块7正确地插装在电源安装槽7内。由此可根据不同电参数规格的灯管，配有不同的接插件防止用户误用，更换电源的操作，用户能轻松完成。其中，对于不同长度及规格的灯管，不同的灯管之间可以具有相同的电源输入插件31和电源输入接插件34，而不同的灯管之间的直流电源输出插件32和直流电源输出接插件33则不同。
为了便于将整个日光灯管的固定，在两个端盖8上分别设置有针脚组件。每个针脚组件包括两个针脚4。
如图3所示，该可换电源灯管在电路结构上主要包括两个部分，即电源模块3和控制模块5，该电源模块3包括顺次电连接的EMC滤波器31、输入整流电路32、输入滤波电路33、变压器34、输出整流电路35和输出滤波电路36。在实际工作中，通过控制模块3对电源模块3进行信号控制，该控制模块3包括顺次电连接的基准电压比较器53、PWM控制器52和开关电路51，其中，基准电压比较器53与输出滤波器36电连接，开关电路51与变压器34电连接。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
