Help me to slove my problem, i am using LM3414 IC to drive 12Watt LED Slim Light at 48v DC, here in my project i am using controller msp430fr5729 to give dimmimg effect to led slim light and this led light is drive by IC LM3414 , now my problem is that i am giving moonlight dimming effect using controller's timer PWM which i get perfectly as per my requirement but the problem is that when i see the effect of dimming on intensity of light in my moblie camera, i get black strip on led which is as shown below. so i want to remove this flicker from the light so what kind of changes i should do in my hardware or in my code so i can remove this black strip on light while seeing its effect on camera. The same Setup when i test on AC constant led driver by giving 230v i get perfect intensity of light when checked from camera, i does not get any black strip on light when check on camera.
here i am attatching the pictures of flicker which i get in my mobile camera, when i had given PWM of 50 dutycycle to led light
here i am attatching the pictures of flicker which i get in my mobile camera, when i had given PWM of 90 dutycycle to led light
i want to remove this black strip at every dutycycle i.e from 0 to 100 which i use for dimming purpose
