The LED (light-emitting diode) market is expected to reach $5 billion in 2007, and the solid-state lighting market is predicted to be $ ... NettetFor circuit #5, if using PWM, I believe R1 needs to be much smaller than 100k. Using 100k, I wasn't able to get the LED to light up at all at very low PWM values (less than about 8 out of 255). With a 330 ohm resistor, the LED produces light even at a duty cycle of 1/255. I think the MOSFET can't switch on fast enough with the large resistor.
