NettetLEDs (that's "ell-ee-dees") are a particular type of diode that convert electrical energy into light. In fact, LED stands for "Light Emitting Diode." (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs. NettetThe result is that an LED bulb may flicker between its on and off states at 100-120 times per second. Figure 1: A graph showing the alternating current waveform, which repeats 50-60 times per second. Even a simple rectified AC signal will cause an LED to flicker at 100-120 times per second.
