Dimming fluorescent lamps is an attractive feature that provides mood and brightness effects as well as having tremendous energy savings potential. Designing a dimmable electronic ballast, however, is ...

In part 1 we discussed rectifying the ballast AC current to DC and we showed an open load protection circuit. Direct replacement of fluorescent tubes with LED assemblies can lead to uneven lighting.

If you want to improve lighting system efficiency, ballast selection is critical. Today's most popular energy-efficient lighting designs involve new ballasts. Because ballast technology is constantly ...

Q: My home is about 20 years old. My problem is with the lights in the kitchen. Sometimes they work and sometimes they don’t. When I turn on the switch, the light flickers or just partially lights. I ...

An electronic ballast, in simplistic terms, takes a mains supply and transforms the energy to a storage capacitor, which in turn powers a half bridge Dr. Dirk Killat, Design Engineer, Dialog ...

The IRS2530D and IRS2158D 600-V controllers from International Rectifier, Inc. are suited for dimming fluorescent lighting ballast applications. According to IR, the controllers promise to boost ...

Beginning in 2005, efficiency standards set by the Department of Energy regulations were phased into effect, covering magnetic ballasts designed to operate full-wattage F40T12, F96T12, and F96T12HO ...
