Removing LED Flicker

February 20, 2012

While upgrading home lighting to a more efficient, cost-effective alternative such as LED lighting is appealing for obvious reasons, a poorly designed bulb can end up being costly in the long run. Moments come and go, but some should be saved for posterity and enjoyed over and over again. With the wrong choice in off-line driver technology, a precious memory risks being lost because of nasty flicker effects.

For more than 50 years families have recorded special occasions with home video from super 8mm to modern HD digital video cameras recording directly to integrated flash memory. With the increasing use of alternative lighting, a new problem has arisen. New LED lighting technology driven from the AC line voltage can cause a flicker that, when recorded onto digital video, becomes visible. A well-designed LED circuit can remove this flicker and guarantee that you will capture those properly lit memories for all time.
