LED Battern lighting is making my video flicker

(1/11) > >>

Hi I need brain stormers. I am building an office / studio / steaming channel for my wifes little cake business. The 2 rooms out of 4 built and now finished are super clean and bright and installed 8 to 10 of these https://www.sal.net.au/products/interior-led-lighting/led-linear-battens-and-profiles/BLADE-SL9709-TC in each room. The idea as we were working from home with studio lights everywhere and now we build this decided to blast heaps of light in the room eliminating studio lights so when she has a room full of students we don't have wires everywhere.

We powered up security camera's, logitech webcams for streaming and phone camera's. ALL produce flickering and unfortunately none of the devices have an option to set a frequency. Logitech can switch from 60hZ to 50hZ but it still flickers but not as bad.

The outlay for all the lights unfortunately has me in a position where budget won't allow to buy a pallet of other lights so now I'm thinking would it be an option to buy 1 more , open it up to get to the driver and modify it somehow to stop it from flickering on video.

I would have thought going from AC power to LED that there wouldn't be a frequency issue. I was convinced that Alternating current would get rectified to DC to power the LED's but clearly I was very very wrong, What am I missing here. Please any idea's or help would be greatly appreciated. Happy to disconnect the light driver and put in something else to power the fixed LED's inside this slimline batten to stop the frequency flicker all together 

Yes the AC is rectified but if there is no smoothing capacitor there will be peaks and nulls.  Each at twice mains frequency if full wave rectifier.

So in that case that gives me hope. I will buy another light to experiment with before I even think about modifying each one. So excuse my novice questions but integral electronic circuits is not my forte! Ok so where would the caps go roughly? Are they across the DC output to the lights or before that somewhere else on the circuit usually?

Once I get the spare batten I will try to draw out the circuit or provide pics of the board for further help

I built my own ceiling lights for the kitchen and used commercial LED lighting power supplies.  I know they have big capacitors in them becuase the lights fade out for a second when turned off.  These lights have 20 LEDs in series and so drop about 70 V.  The power supplies are Thomas Research Products LED25W-72-C0350 from Digi-Key.
So, these ought to eliminate flicker, too.  These supplies will run strings at 350 mA from 36 - 72 V, so that is about 10 - 20 LEDs in series.


First, for a studio, a CRI of ~80 for your LED lights is lousy. Sorry, but it can get too cheap.
Second, for this kind of application, I'd never go for LEDs. For beautiful colour rendering, halogen rules.

Now for a solution. Can it be (it's about baking, after all) that you have three-phase service?
If so, patterning your lights onto all three phases might solve it. That's then just a rewiring issue.
