Incandescent Lamp Inrush Current Limiter
This circuit limits the large inrush current often associated with large
incandescent lamps. With the components shown the current is limited to 1 amp,
but it could be scaled to any desired current. (added 7/06)

Idea for a Low Voltage Light Dimmer - A light dimmer is a means of controlling the
"brightness" level of a lamp, in this application we will use a555 Timer to control
the brightness level of a low voltage incandescent bulb of up to 60-Watts. For the
light dimmer to work the555 Timer is configured as a "variable cycle", astable
oscillator running some where around300 Hz. (added 4/02) |

Instrument panel lamp dimmer control Circuit - This circuit uses an MC3392 low
side protected switch and an MC1455 timing circuit to form an automotive
instrumentation panel lamp dimmer control. The brightness of incandescent
lamps….(electronic design added 09/08) |

IR21571 Ballast Control IC Design Kit - The IRPLLNR2 is a high efficiency, high
power factor, fixed output electronic ballast designed for driving rapid start
fluorescent lamp types. The design contains an EMI filter, active power factor
correction and a ballast control circuit using the IR21571. This demo board is
intended to ....(added 3/05) |

IR21592 Dimming Ballast Control IC Design Kit - The IRPLDIM1U is a high
efficiency, high power factor, dimming electronic ballast designed for driving rapid
start fluorescent lamp types. The design contains an EMI filter, active power factor
correction and a ballast control circuit using the IR21592. This demo board is
intended to ease the evaluation of the IR21592 Dimming Ballast Control IC.... (added

IRPLMB1E: 25W 230VAC Small Size Ballast using IR2520D - The circuit is built
around the IR2520D Ballast Control IC. The IR2520D provides adjustable preheat time,
adjustable run frequency to set the lamp power, high starting frequency for soft start
and to avoid lamp flash, fault protection for open filament condition and failure to
strike, low AC line protection and auto-restart after line brownout conditions. line
brownout conditions. (added 3/05) |

Japanesque Ceiling Light - This is a Japanesque ceiling light without any
electronics. Everybody will able to build easy even if they have no electronic skill.
