  • Digitally Addressable DALI Dimming Ballast App.
    This reference design is a high efficiency, high power factor and digital dimming electronic ballast designed to drive rapid start fluorescent lamp types. The design contains an active power factor correction circuit for universal voltage input as well as a ballast control circuit using the IR2159
  • AN0012 Electronic Lighting Ballasts
    All fluorescent lamps require a ballast to provide the electrical power to preheat the lamp electrodes, strike the lamp, provide the running power and control the discharge current. This can be achieved by either electromagnetic or high frequency electronic ballasts. With the introduction of new
  • Bright future for energy efficient lighting
    New integrated circuits promise to make fluorescent lamps more "green. " Light it up International Rectifier devised this demonstration of a new CFL ballast chip for the device's European debut. In the U.S., Technical Consumer Products will make lamps incorporating the new chip under
  • Green Technology: How to power an energy-efficient light
    New lamps are more efficient, but what about the electronics? Designers need to learn a few new tricks about driving LEDs and CFLs. It isn't just more-efficient lighting that is driving down energy bills. Compact fluorescent lamps (CFLs) and LEDs wouldn't be found in many light sockets today
