Frank’s LED dimming circuit is based on a 555 Timer chip. The fixture is only pulsed long enough with the 12 volts to establish the desired brightness level. This method overrides the “avalanche” ...

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 ...

In these scope photos and spectrum analyzer shots, the probe is connected across the 555 output/LED fixture at different LED intensities. The Enemy of LEDs San Francisco contract and project engineer ...
