Hello electro tech online
I am working with LED and trying to make them as bright as possible.
What I have read, I can provide higher current through the LED with pulses. I am now running a 30 ma LED with 90 ma and pulses. 1khz with 1/10 duty cycle.
I was trying to measure the light intensity, but there is no difference between a normal none wave setup wtih 30 ma, compared to my PWM setup.
The measurements was done with a photodiode and I measured the voltage after. Can this be a bad way to measure the light and therefore I cant trust the outcome, cause maybe it shows more the average light intensity/voltage.
