谁能全程指导下 电路
谁能指导下我想做些简单的 灯牌 电路怎么设计啊??电源怎么设计多少伏的 怎么变比较划算
请指教 谢谢 (1)灯箱制作材料:
外框:一般用铝合金型材制作。 光源:发光二极管(LED) 面板:吕塑板。 支架:一般用木条或者铝合金支架。控制器:单路,2路,3路,5路,13路等(新品有多功能三合一)(控制器的作用是把220V的交流电变成220V的直流电。再加上控制本身电路功能达到各种变化的效果)(2)灯箱常用工具:电钻(4.8或4.5mm的钻头)、烙铁、小手钳、胶枪,有机玻璃胶。步骤:(1)、在板上做出需要的字样(一般用机子贴)或者图案(2)、用手电钻或者雕刻机打出与LED二极管直经大小一样的孔。(3)、每个字或图案里的LED灯为串联(二级管长腿为正极,短腿为负极,长腿和短腿拧在一起,即为正负拧在一起,用烙铁焊在一起更好.也就是串联了),一般一组串联(红色不超过115个,蓝色不超过73个,绿色不超过80个),所加电阻数与LED灯个数之间的关系如图:红色和黄色超亮LED数
串电阻值蓝色超高亮LED数串电阻值绿色和白色超高亮LED数串电阻值其他颜色的超高亮发光二极管的个数和串入的电阻值可以自己试验可得,主要的是电流必15—20mA。

(4)、字与字或图案与图案之间一般为并联。(5)、所有的LED灯连接好以后,一般要用胶枪把它们给固定密封。以防脱捍和进水。注意LED所有两引脚一定不要短路。(6)、根据的所需来连接控制器不同的线,展示出不同的闪烁效果。 什么样的灯牌,实现什么功能,需要什么花样,方便什么电压? 我要做 最普通的电子字牌!电路怎么设计啊?就两个字发光就可以的 周围放些跑马灯 5# 恒光灯箱
这位大歌说的很好呀,我很欣赏你的头像,设计的很好,很形象。 好,好的很!!!!!!!! {:1_146:}谢谢各位!!!! 恒光电源谢谢您啊~~祝您发财
学到很多哦 恒光电源????楼主没看清楚吧? 哈哈哈~~~灯箱变电源了!!{:1_114:} 回答的太好了 ,就差手把手的教了。学习了。 看起来不错,学到很多哦 学习了呀!很好的东西! 受益匪浅-真的有东东要好好学习! 受益匪浅-真的有东东要好好学习!——本文来自〖www.521LED.com〗原帖地址:http://www.521led.com/viewthread.php?tid=794&fromuid=1072 受益匪浅比偷师实际多了 {:1_144:}我偷的送你 !初来乍到 问别人好久的问题 到这来 就 迎刃而解 还是 论坛好 技能学 也能看 而且高手如云 接触的环境 决定了学习的档次
