PWM LED Dimmer

Convenient Led Management

Innovative solution to the impractical control of LED strips integrated into furniture by their manufacturer. Let's make them more intuitive to use and add a feature that unlocks their full potential.

Impractical control of integrated LED devices

Have you ever been annoyed by the sheer number of switches that come with furniture featuring integrated LED strips? Manufacturers almost always choose the cheaper option: a separate low-cost switch for each part of the furniture. This results in an impractical number of independent switches that can only be turned ON or OFF

That’s why I came up with a solution to this problem. What if we could wire all the LED strips to a single device that would power them, monitor them, and—most importantly—control their ON/OFF state? And while we’re at it, why not manage the brightness as well? LED strips can be far too bright during cozy evening hours. Of course, we should also include some essential protection features.

The result is my second-generation PWM dimmer, featuring adjustable, reprogrammable code on an onboard MCU and silky-smooth PWM dimming. This solution lets you choose your style of dimming. it can work with an 10kOHM potenciometers of all sorts from knobs to sliders.

Testing

1st iteration successfull 1.5 year real life test

1st iteration successfull 1.5 year real life test

The first itteration of the PWM led dimmer has proven itself functionable and as a prototype it managed to workk in a home enviroment dimming LEDs for 1.5 years without showing any signs of wear upon inspection. This test layed the foundation for the 2nd. Itteration
