This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

The occasion for this project was retrofitting an illuminated wall picture with LED backlighting. As soon as I applied LED power, the brightness blinded me — much brighter than the original T20 ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

The concept: find a COTS* motorcycle LED light dimmer that can be spliced into an auxiliary LED light array to vary the light output. We found this “Rotary LED Dimmer”, made by ADVmonster and designed ...

1. A Cree XM-L RGBW high-power LED can be driven by two LT3964 LED drivers for accurate 1:8192 per channel dimming. 2. Typical driver architectures offer 8-bit color resolution. Implementing a driver ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...
