Integrated smart LED dimming for cooker hoods – patented technology

E.D.&A. has developed a new and patented technology. Smart SMPS -Switched Mode Power Supply- is a mechanism to get two independently regulated voltages out of one power supply circuit. The patented E.D.&A. principle enables the continuous-dimming setting of the LED lighting.

Integrated smart LED dimming for cooker hoods

This technology results in a compact and low-cost solution: a cooker hood controller with an integrated smooth dimmable LED driver. No need for external LED drivers, so less assembly and wiring costs! It is clear that the controller can also include IoT technology and customized user interfaces. All required functionality combined into one controller board. (EC fan control, dimmable LED driver, RF communication, Wifi, Bluetooth, IoT, etc.)

Unique, innovative solution results in a patent

It is not so difficult to obtain different voltages, with a mutually fixed ratio, from one power supply. With a dimmable LED power supply or a motor controller, we also need a variable voltage besides the constant voltage for the control circuit. This therefore means that all other voltages vary too, which is not always desired.

A traditional solution is to create two switched mode power supplies next to each other: one constant and one variable with two separate transformers. Or you need an additional converter to regulate the voltages.

This had to be made more compact and flexible! 
We wanted to integrate this into one single coherent and cost-effective design. After a great deal of research, we found an innovative solution. That solution turned out to be so unique that we patented it.
