#127127 - my narrowest pulse is ~30us and they glow Responding to: ???'s previous message |
but does anyone here have any experience of driving LEDs at low duty cycle.
when ambient light is the lowest, the PWM pulse is ~30uS repeated every ~2ms. This works just fine. I do not know if you mean "low average" or "narrow pulse" so, you determine if the above helps. PS you may be better off not using white LEDs, if you can not use 'colored' light, using RGBs may work better. Erik |
