The post explains a circuit that will switch off a group of lamps in sequence with a predetermined delay rate, as set by the user through a built in pot. The ideas was requested by Mr. Azam Jamal
技术规格
I want to make a circuit which works like: I have 9nos 25 watt CFL bulbs and I want that when I switch off the first bulb then after each 5 minutes the remaining light would switch off regularly like each should go off after 5 minutes of other means that in 45 minutes all 9 lights go off respectively.
请帮我 ？
该设计
电路功能可以理解如下：
下面的第一电路是简单IC 555和IC 4017灯追踪器以5分钟的速率产生灯的基本排序，该速度由100K罐设置确定的时间频率。
必须设置它以产生可能为所需排序率的50％的频率，这意味着它必须设置为以2.5分钟的速率产生开关的时段。
The second circuit is a simple a SCR based relay driver circuit which needs to be repeated 9 times across the intended outputs of the 4017 IC.
根据要求，只要SPDT被切换到地面位置，IC555保持禁用，第一灯（1）无限制地开启。
同样在该位置，IC 4017的所有引脚从PIN2向上锁定在零电压下，这意味着连接的SCR中继驱动器在其N / C位置中的继电器确保所有连接的灯保持接通。
So all the nine lamps from pin2 to pin11 of the IC 4017 is now in an activated position along with lamp1 associated with the SPDT transistor relay driver stage.
在转换SPDT时的所需时段，第一灯（1）被关闭，并且使用其计数过程启动555个定时器电路。
5分钟后，555 IC将其第一个合法脉冲输入到4017制作PIN2的PIN14，以便高亮，这又锁存了相关的SCR继电器驱动器在序列中关闭第一灯。
After another 5 minutes pin4 goes high switching OFF the associated SCR relay driver lamp, and the process repeats until the last pin11 in the sequence gets activated, switching off the last lamp in the sequence, and this also locks pin4 of the IC555 freezing the whole circuit until the operations are reset by the user for restarting the cycle afresh.

Hi Swagatam,
非常感谢您所有的伟大的原理和解释。
您的电路在周期性序列中切断灯，让我认为可能是该电路的修改版本可以帮助我生产起居室电路。
I would like a circuit that turns on / off outputs in a random order. Simulating a living house or an office building where the light goes on/off in different rooms. Each output in random order if possible. Eg. Room 1 could stay on while 2 turns off etc.
The circuit is for my model railroad track.
The circuit should auto reset when all outputs has been raised.
我希望你能理解我的意思。
非常感谢你提前，

嗨Henrik，谢谢，
实现所需的应用程序甚至更简单。
You can use a 4060 timer IC in its standard form and out of its 10 outputs select the desired ones as per your liking and configure these with a transistor relay driver stage.
The selected outputs will provide a random set of ON/OFF switching to the connected lamps.
you can vary the timing of the lamp ON/OFF through a pot and also try other outputs for varying the randomness of the switching.
You can find plenty of simple 4060 timer circuits online, or even through this blog.
Hi Swagatam,
Thank you very much for your reply.
我在建筑电子产品中很新，所以如果我问愚蠢的问题，请原谅我。
是否可以同时在4060 IC上保持更多的输出？
如果不是我可以用晶体管继电器驱动器将其高电平持有电容器？
我想将LED连接到输出，并在随机顺序中同时亮起。
I see that pin 7 is the first output and pin 5 the second and that output 5 generates exact the double time period of pin 7 from your Simple Timer Circuit Using IC 4060.
这是否意味着输出7保持高1秒。输出5保持高2秒，或者输出在高电平之前的时间段？
顺便说一下了you get my question about detecting a model train locomotive? I was so foolish to ask you through Google Hangout which I never use. Can I post my question here or by email?
Again thank you very much for helping us newbies.
嗨Henrik，
Yes it's possible to get a high on several pins at a time, and yes it's also correct that from pin7 onwards upto pin3 sequentially generate a 2X time interval that is twice the time interval of the preceding one or 1/2 the frequency of the previous pinout.
如果可能，我还没有在聚会聊中看到你的问题，我会检查一下。
Hi Swagatam,
感谢你的回复。
我很抱歉再次打扰你，但我没有如何持有更多的输出高。我试图使用4060 IC学习其他电路，但它们主要是定时器电路，并且只有1个输出一次。
将电路连接到12V DC后，我想实现的。
电路应随机打开输出，其中更多的输出可以保持高电平时间，然后关闭。当电路完成所有输出时，它应该重置以全部开始。
Would you be so kind to help me out here? I would be very grateful for your help.
先感谢您。
我会向您发送问题的问题。
嗨Henrik，
You can use pin1/2/3 of the IC for achieving simultaneous switch ON of the loads for some period of time, for example, if pin3 is set to be ON for 8minutes, pin2 will be ON for 4minutes and pin1 for 2 minutes…meaning for 2minutes all the three lamps across these outputs will ON together, or for 4 minutes at least 2 lamps will be ON….if you use other subsequent pins, then you may get at least 5 lamps simultaneously ON for at least 1mnute or 6 lamps ON for at least 30 seconds and so on….
