一.前言: 随着LED的普及,以LED点阵为基础的显示设置层出不穷.例如,公交车的线路提示牌.高速公路的信息提示牌,安装在大楼上的广告屏幕等.下面,我们将由简单到复杂地探索各种LED点阵的使用方法,同样是基于Proteus的arduino仿真,以arduino uno R3为例,包含以下三个实验:LED点阵显示表情.LED点阵跑马灯.回纹灯.具体介绍如下: 二.仿真电路设计: 本次的三个实验用到的电路连接都是相同的,构建一个电路仿真图即可,仿真图如下: 电路图比较简单,只需将arduino最小系…

1.LED驅動芯片直流額定輸入電壓范圍應當8 - 40 v,覆蓋廣泛的應用需求.最好的壓縮能力大于45 v.當輸入交流12 v.24 v,簡單的橋式整流器輸出電壓可以遵循電網電壓波動,特別是在高電壓輸出直流電壓會偏高.如果驅動器集成電路沒有寬輸入電壓范圍,往往會將擊穿電壓電網,燒毀了LED光源.2.led驅動芯片大于1.2 ~ 1.5額定輸出電流要求.照明的LED光源,1 w功率LED光源的額定工作電流350 ma,額定工作電流的3 w功率LED光源700 ma.大功率LED光源,需要更多的電流…
