In the market there are a lot of LED lamps that advertise that they are Dimmer compatible.

Testing few of these LED lamps has proven that they are not so compatible.

Maybe because they have a specific voltage range (80-260 volts AC) that they operate besides other reasons.

My client asks for a dimmer design with a controller so that he can set the lower and higher limits, memory and operation in general. That is the easy part.

The difficult is power part of the circuit. After a lot of search I think that the best is to use trailing edge control with bridge and transistors. If anyone has experience in this or has any other working idea, please reply.

Thanks,
