路灯自动控制电路

⑴ 路灯自动控制的继电器电路设计

我觉得用可控硅好，电路简单，寿命长。

如图，左边两端接220v，右边那个端口接单片机的I/O口。

⑵ 路灯自动控制装置 设计电路图（自己实践的）

呵呵，这个没有知道你要什么样的，本人是搞电子电气的，可以说说你的方案探讨一下！看能不能用得上我的愚见！！

⑶ 如图为路灯自动控制电路，其工作原理利用了电磁开关和光敏电阻．图中虚线框内是电磁开关的结构示意图．

一：A

二：1：自动开关

三：秋分昼夜等长夜晚灯耗电，线圈不耗电25W=0.025KW*12=0.3kW•h

白天灯不亮线圈耗电，36v*0.04A*12=0.0172KW

一昼夜总耗电0.3+0.0172=0.3172KW

四：保护电路不能影响电路原有功能，有光照是继电器线圈电流不能小于40MA

36V/40MA=900Ω所以保护电阻不大于900Ω

⑷ 路灯自动控制电路

电路如下图所示，220V交流电通过灯泡H及整流全桥后，变成直流脉动电压，作为正向偏内压，加在可控容硅VS及R支路上。白天，亮度大于一定程度时，光敏二极管D呈现底阻状态≤1KΩ，使三极管V截止，其发射极无电流输出，单向可控硅VS因无触发电流而阻断。此时流过灯泡H的电流≤2.2mA,灯泡H不能发光。电阻R1和稳压二极管DW使三极管V偏压不超过6.8V，对三极管起保护作用。夜晚，亮度小于一定程度时，光敏二极管D呈现高阻状态≥100KΩ，使三极管V正向导通，发射极约有0.8V的电压，使可控硅VS触发导通，灯泡H发光。RP是清晨或傍晚实现开关转换的亮度选择元件。

安装与调试：

安装时，将装焊好的印制板放入透明塑料盒内并固定好，将它与受控电灯H串联，并让它正对着天幕或房子采光窗前较明亮的空间，避免3米以内夜间灯光的直接照射。调试宜傍晚时进行，调节RP阻值的大小，使受控电灯H在适当的亮度下始点亮。

⑸ 求！！！！！！路灯自动控制电路··

We have been so quiet sitting, enjoying a quiet moment, my mind from time to time the emergence of a naive, if always with him dependent and rely on, side by side clothes, that is how happy a thing. But I know that this is just wishful thinking, even if he knows who is in front of the Ya-Fu, he could not belong to me only one person, after all, he was once the monarch, emperor generation NBA throwback Jerseys, how can one person alone is mine. Looked at against my legs still pray on, it seems already to sleep discount jerseys, very peacefully, Although my legs numb, but not daring to move. For fear of disturbing his sleep at the moment wow accounts, and then look long night sky, while the rich have long since closed block the north.

wind whistling outside soccer jerseys, slightly red sandalwood wood to cover the outside scenery greet my eyes. It seems to snow, a sudden influx of poetic inspiration in my heart, I Dinan cheap soccer jerseys, "Night Snow at first know, when you hear the sound of bamboo off." Faintly heard outside Explorer eunuch Xugong Gong artificially low voice, and I shocked, and even today, I too forget the limelight, and the Queen to see if I am actually in the emperor's chambers dre headphones, will be dire. Pray rhinoceros suddenly opened his eye, Hai a me jump replica nfl jerseys, he was awakened by the sound outside, or not sleep? He gently leaned my head long leg lift Throwback football jerseys, Xing Zhong Wang Leyan closed with red-lacquered doors, lazy said.

"Let her come! He promised me a voice, playing the body immediately from the long bed the sky, his legs no longer perceived, they graally came the slightest pain nfl jerseys wholesalers, tingling with the thrill of little, very hard to accept. Moreover, I still barefoot standing. When the red-lacquered doors open, a jeweled Du Wan into the threshold, send a little snow hanging points are not dispersed, and pray for the king has returned to the previous state, proudly sat on the bed, the arrogance of the Du Wan, "the emperor, how can your let the humble slaves to the Hall of Mental Cultivation! "She slightly agitated Cheap Baseball jerseys, stood alone with the finger of silence from me.

⑹ 怎样设计一个路灯自动控制电路白天灯自动灭晚上自动亮　最好是电路图哟

下图是一个简单光敏电路，光度越大，光敏电阻阻值越小，反之越大。R2调较适当光暗度，继电器输出接所需的灯具，LED等。

⑺ 设计一个路灯自动控制开关电路，能在天黑时自动点亮路灯，天亮后又自动关灯。要求：用光敏元件实现自控；

分两个部分：
1）是光敏电路，用以产生开关控制信号，电路形式多样，可参考网版上的；
2）控制市电通断的权开关电路，有采用继电器等机械式的，也有采用（单、双向）可控硅作为开关部件的，由于可控硅工作在交流电环境下，所以大都采用光电管耦合方式，来接收控制信号-----光敏电路输出的信号；
你可根据负载功率来选择电路----光耦合双向可控硅电路（网上）

⑻ 某同学设计了一个路灯自动控制门电路，如图所示，天黑了，让路灯自动接通，天亮了，让路灯自动熄灭。图中
