تعداد صفحه : 2Example LED Driver Circuit Running an LED with pulses to get maximum brightness To give maximum brightness an LED needs to be driven by a pulse circuit. In this way, it is possible to put 0.5 Amp current pulses through an LED at a frequency of around 100Hz which fools the eye into thinking that it sees a continuous light. If the LED is run at 0.5 Amps for very long, it will burn out (usually within a fraction of a second). By keeping the pulse duration relatively ...
