A recent News item on the LEDs Magazine website describes how the Taiwanese chip maker Epistar plans to introduce AC-LED chips in the near future.
AC-LEDs offer advantages compared with conventional DC-driven LEDs, such as the elimination of AC-DC converters and their associated conversion losses and reliability issues.
Share your views on the potential for AC-LED technology in the lighting market.
Are there any significant drawbacks with this technology approach, at a device, light engine or fixture level?
Or will lighting manufacturers see major benefits in the AC-driven approach?

Hey,
I stumbled across this site because I'm a huge fan of all these great new scoreboards going into new stadiums now. And what does that have to do with your blog, you may be wondering? Well, they're all powered by LEDs rather than incandescent bulbs.
I recently went to New York's new Yankee Stadium, and the baseball scoreboard there is a technological marvel - 59ft X 101ft. The resolution is so clear and crisp -- it's got to be beyond hi-def, if that's possible.
And the amount of information they put on there is unbelievable -- not just the score, but radar speeds on pitches, messages from fans, player information with pics. Oh, my God! It's entertainment in itself -- this scoreboard.
It feels good, too, knowing that these boards, big as they are, save money using LEDs.
I recently read a great article on the advantages and marvels of LED scoreboards at www.electro-mech.com, a Georgia company which makes football scoreboards, baseball scoreboards, hockey scoreboards for schools all over the South.
Hard for me to believe these new generation scoreboards are even in high schools these days. Wow.
The article is an interesting read. And even though it's about sports, you LED-ophiles may like it. Check it out: http://www.electro-mech.com/
definitely industry will benefit with ac leds. power saving in conversion
