Hello,
I found the need to learn about electronics when improving the lighting in my office.
I currently have two strings of leds, all leds are run in series. Each string has 23 leds with 6v forward voltage and I am running them at 175 milliamps. The power supply is the following: HLG-120H-350A. These leds came out of the back-light panel of an LED tv, a local tv tech said it was alright to run them at these specifications, or at or below 200 milliamps.
Here is the issue, I am getting a bit of eye strain with these. I took them by the tech's office and he said the ripple or noise in the line is at 7.2 khz. If I add a capacitor and/or an inductor can it take care of noise at that level?
I guess my basic question is will an inductor or capacitor smooth out the current at the 7.2 khz level to the point that it raises the ripple to something like 45khz?
I want less interference. To me that means raising the khz noise in the line to the point it can't be noticed. Any input on this would be awesome.
Thank you,
Patrick
