Simple LED driver

Description

This model is a means of driving and dimming your LED’s. By changing (or switch off) the light intensity of the LED in different ways, you get different colors and effects. This is the main secret of the lamps I have posted this year. It’s the simplest way I could think of to make this driver/ dimmer :-). Basically it’s just a case with 3 potentiometers and 3 transistors (or FET can also be used like a BUZ11) that dims the voltage. This is a follow up part for the adjustable LED base: https://cults3d.com/en/3d-model/tool/adjustable-led-base. If you have your LED’s and the right resistor (I have talked about in https://cults3d.com/en/3d-model/tool/adjustable-led-base) you can make this driver case. I included a schematic for connecting the parts. Because it’s so simple, I didn’t even make a PCB, but soldered the parts directly together on the potentiometers themselves. The transistor is only needed to handle the current and it’s cheaper than buying a 5W potentiometer. The 15K resistor is just a limiter so the potentiometer has a better range. If the range does not work for you because the LED is already at max level when the potentiometer shaft is only at 50%, than you can replace this resistor with a 50K potentiometer to “fine tune” it. Than you need a case to hold the parts together and I kept it very simple. There is a main housing end 2 different type of baseplates. One has extra mounting options. Also the one with external mounting option has a build in cable tie. The…
