Description

I need a circuit designed (please include part numbers). The circuit will allow LEDs to be powered by 120 AC 60 Hz and must allow the LEDs to be dimmed by a device that I have that uses Pulse-width modulation. I will use the circuit to build 3 seperate devices, 1 using Green LEDs, 1 using Red and 1 Blue. The output of the LEDs should be close to the output of a 10-20 watt incandesent light bulb and should have a beam width should atleast 60 degrees and should allow atleast 6 LEDs bulps. The circuit also should allow any number of the LEDs to fail without having any negative affect on the others.

I have designed many power circuits for many years. I will make sure that the parts I use are easy to buy, not expensive and easy to assemble. The circuit will work well and it will continue to be reliable. I have also designed many LED circuits and understand the requirements well. Therefore I have confidence that I can deliver this circuit with all part numbers in 2 days. You will be very pleased with the result.
