很高兴为您解决问题。
1，首先是材料的选择，建议选择3.3v的led，这样便于设计电路。
2，然后按照机箱空间的大小，确定我们需要制作电路板的尺寸，把它切割成我们需要的样子，切割完成之后轻轻打磨电路板边缘，去掉毛刺
3，打磨完成后，我们可将led喷涂上白色的涂料，让led灯光效果更明显。这时我们就可以将LED插入电路板了。正负两极分别插入两个电路，方便我们走线。
4，插板时，先将两个LED先并联，然后公共的正极和负极分别再连接到总线上。这里我们没有采用680欧姆的电阻进行分压，所以应该直接用3.3V供电。然后连到总线上，这样就可以使用12V供电了。
5，电路完成后就是焊接引线了，为了防止引线折断，我们使用热熔胶固定。最后取出硬海绵，将一段抹涂上热熔胶棒，立刻固定到机箱的内部，静置一分钟，电路板编牢牢固定在机箱内壁了。完工

你好，如皋led灯是12V直流电，那应该就是接电脑电源的12V上，或者主板哪有输出12V的也行，注意正负极别反了。但如果两者是是交流电的，那没办法接电脑上了。希望可以帮助到你

不必再拥有 07-06 05:52

您好，1、灯带需要配置专用LED镇流桥插头才可以使用，灯带不配置插头是不可以使用。
2、灯带插头是根据您的段数来配置，需要几段灯带，就需要配置对应的插头。
3、用12V直流也许加个稳压电容和恒流二极管能点亮，或者买个能和灯匹配的12V直流输入的恒流驱动电路，灯是12V，功率4.8W，电流大概就是400MA，需要一个12V输出电压，电流大概400MA左右的恒流电源。
4、家装用的220V电源的LED灯带，直接买专门为电脑机箱设计的LED灯带，插在机箱电源的大4P接口上就能用。
希望我的回答对您有所帮助
