Design Electronic Circuit to power 10 W to 50 W LED using AC Supply. I am using a relay triggered by Raspberry Pi. I need to operate a LED as soon as the GPIO of Raspberry Pi goes high. The problem I am currently facing is that the LED drivers I have purchased of the shelf take few mili seconds extra time to light up the LED. I need a power solution to start the LED as soon as the raspberry pi gpio go high!

Hello, Have a great day. We will build the circuit in our lab and online demo of the hardware will be given. The problem is due to AC starter kit present in the LED power supply. We need to have proper relay or Triac to trigger the AC load. Please feel free to contact us. Regards, Shahbaz.

Hello! Ready to start right now and complete this as soon as possible, also please tell operating voltage of LED as it is more relevant and I can design both ways, using readymade components or make a raw one which could be cheaper.

Dear Mr or Mrs Please specify concerning: 1. Will you need schematic only or PCB as well? 2. If PCB: a)what is the max budget/unit (cost of components)? b)what is the max/min sizes of PCB? c)how long it should work? d)What is the AC voltage? (110V; 220V; etc) If there are no very special requirements I should do schematic + PCB within 3-5 days
