Description

安全LED灯管
技术领域
本发明涉及LED(发光二极管；Light Emitting Diode)灯具技术领域，更具体地说，是涉及一种可防止用户在安装过程中遭受电击的安全LED灯管。
背景技术
近年来，LED灯具因为、节能、更环保、效率高、体积小、寿命更长等特点而备受关注，LED灯具正在取代传统的白炽灯和荧光灯管而作为主流照明工具。与此同时，随着清洁能源效率技术的发展以及人们环保理念的日益增强，越来越多的家庭和机构都将采用LED灯具进行照明。在这种趋势之下，确保LED灯具的绝对安全，防止触电等潜在的安全问题，就显得尤其重要。
请参照图1及图2，现有技术中的LED灯管100包括散热外壳110、灯罩(图中未示出)、位于所述散热外壳110和灯罩两端的端盖120、通过电连接件145电连接在一起的两个电路板150、位于所述两个电路板150上的LED灯珠170、位于所述端盖120上的插针180以及分别与两个电路板150连接的驱动160。其中，驱动160通过绝缘纸包裹后被置于散热外壳110内，这种结构的缺陷在于，容易导致散热不畅。另外，在现有技术中，上述各部件的连接是通过胶水粘结的方式实现，在长期高温条件下，胶水连接容易老化损坏，从而造成安全事故。
更为重要的是，当消费者安装上述LED灯管的时候，还存在着更大的安全隐患。例如，当在传统荧光灯灯座上安装LED灯管的时候，如果消费者将图中所示的插针插入灯座高电压的一端时(俗称火线)，虽然在驱动160与中性线(俗称地线)没有构成回路，其中没有电流通过，但其中已经存在一定的电势，当如果消费者此时触碰到另一端的插针的时候，就会遭受电击，从而发生安全事故。
市面上所有的LED灯管都存在上述安全隐患，并且没有采取相应的安全措施加以防止。消费者是否被电击，取决于插针是否先被插入灯座高电压的一端。因此，消费者存在50％的被电击危险。
发明内容
本发明所要解决的技术问题在于提供一种安全LED灯管，其可防止用户在安装过程中遭受电击。
为解决上述技术问题，本发明的技术方案是：提供一种安全LED灯管，包括散热外壳、灯罩、位于所述散热外壳和灯罩两端的端盖、与所述散热外壳固定连接的电路板、位于所述电路板上的LED灯珠、位于所述两个端盖上的两组插针以及分别与电路板连接的驱动部分，在所述驱动部分与所述两组插针之间的电路上分别设有防护开关。
这样，不管用户是否将插针先插入灯座高电压的一端，只有在两组插针都被安装于灯座内后，再启动防护开关，才能使市电源与驱动部分之间形成电连接，因此彻底消除了用户安装过程中的潜在危险。
附图说明

图2是图1的电路原理示意图；
图3是本发明一较佳实施例除去灯罩后的立体示意图；
图4是图3所示实施例的电路原理示意图；
图5是图3所示实施例中的端盖的立体示意图；
图6是图3所示实施例中驱动外壳的立体示意图；
图7是图3所示实施例除去端盖后的侧视示意图。
具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚明白，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。
请参照图3及图4，为本发明的一较佳实施例，该安全LED灯管包括散热外壳201、灯罩202(请参照图7)、位于所述散热外壳201和灯罩两端的端盖260、与所述散热外壳201固定连接的电路板205、位于所述电路板205上的LED灯珠214、位于所述两个端盖260上的两组插针250以及分别与电路板205连接的驱动部分400，在所述驱动部分400与所述两组插针250之间的电路上分别设有防护开关220。这样，不管用户是否将插针250先插入灯座高电压的一端，只有在两组插针250都被安装于灯座内后，再启动防护开关220，才能使市电源与驱动部分400之间形成电连接，因此彻底消除了用户安装过程中的潜在危险。
以下对上述各组成部分分别作进一步详细介绍。
请结合参照图7，所述外壳201的横截面大致呈半圆形，并可采用铝、铜等导热性能良好的金属或合金材料制成。其对应LED灯管出光面的一侧形成用以安装固定电路板205的安装平台。安装平台对应电路板205的位置设有若干供螺钉锁紧的螺孔。从而解决了现有技术中，采用胶水实现电路板和外壳之间连接的容易老化失效的缺陷。在所述安装平台两侧延伸出具有安装槽的定位部，用以实现与透明灯罩的连接。为了扩大散热面积，所述在与LED灯管出光面相反的一侧形成多个条状突起。另外，在所述外壳201的长度方向上设有贯通所述外壳201的通孔，便于空气流通而散热。
本实施例中，所述防护开关220可通过机械按键控制或遥控的方式实现通断。当采用机械按键控制时，可采用现有技术中的机械按键。当采用感测方式时，可采用红外感测器、电磁感测器、光电感测器等。
请结合参照图6，所述驱动部分400包括与所述散热外壳201通过螺钉固定连接的驱动外壳401、位于所述驱动外壳401内的驱动等。所述驱动外壳的两端分别延伸出一法兰结构411，用以与所述外壳201固定连接。本实施例中，所述驱动外壳401呈半圆柱状并具有与所述散热外壳内腔方向一致的容纳空间412。另外，所述驱动外壳法兰结构411一侧与所述散热外壳201之间形成散热通道404。
请结合参照图5，所述端盖260包括端盖壳261、位于所述端盖壳261内的端盖电路板(图中未示出)，端盖壳261上设有防护开关安装孔和供所述插针250插设的插孔。本实施例中，所述插针250和防护开关220与所述端盖电路板固定连接。
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。
