12 Volt DC Fluorescent Lamp Driver: This fluorescent lamp driver uses a
normal 120 to 6V step-down transformer in reverse to step12V to about350-Volt to drive
a lamp without need to warm filaments. (added 4/02) |

20ma LED Ballast: I use this circuit for general use to power white LEDs,
like a headset light I use on my desk and a keyboard light for my computer. I built it
into a tiny Radio Shack project box (270-288), which y no longer sell. I put
heat-shrink tubing around female output connector (RS P/N 273-1743), so that
contacts are not exposed, but you can still plug and unplug it.

8w Fluorescent Lamp Inverter: Compact DC-to-AC Inversion for Efficient Lighting
Systems: Zetec Semiconductors Applications Notes An enhanced TO92
packaged one transistor design that uses a minimum of components, and yet achieves
performance and efficiency normally associated with much larger packaged switching
transistors. The design is optimised to provide a fast turn-off condition for
transistor, reby allowing inclusion of 80V, 2A DC rated ZTX652 yielding
efficient and reliable operation. Typical waveforms and full circuit details are
provided. (app note added 2/06) |

A Ballast that can Be Dimmed from a Domestic (Phase Cut) Dimmer.: A system
has now been developed, based around IR2156, where ballast is able to
operate with minimal flicker over a considerable portion of adjustment range of
a dimmer and light output may be controlled over this range from maximum output
down to around 10%. (added 3/05) |
