Digitally Addressable DALI Dimming Ballast: (circuit / schematic design added 6/06) |
|
Digitally Controlled Dimmable Lighting: This project implements the control of 2 lighting sets using a PIC18F252
microcontroller. The advantage of the digital controller is its increased flexibility. The brightness of the light sets are controlled using phase angle firing method, but with the intention of
investigating the implementing of a burst firing method. (added 6/06) |

Dimmer Circuit for Normal Light Bulbs : (electronic design added 9/02) |
|
Dimmer Switch : This dimmer switch is suitable for230-Volt incandescent lamps with a total power of up to300-Watts. The circuit
is wired in series with the lamp so it can directly replace the wall switch. (added 4/02) |

Dome Lamp Dimmer: Efficiently dim the cars dome or map light (low voltage light), PDF file (added 4/02) |
|
Dome Light Dimmer for Cars: This unique circuit makes your dome light look cool. Usually when the car door is closed, the dome
light just goes OFF. With this circuit, you can have our dome light fade slowly in brightness and finally go OFF. This slow dimming of the light gives a very good feeling at night. It looks very
romantic!.... (added 11/06) |

Electric Power Controller: suitable as dimmer for 100-Volt lamp up to1200W (app note added 4/02) |
|
Electronic Transformer DIMS Halogen Lamp: 05/11/00 EDN-Design Ideas / (added 5/02) (several circuits in PDF) Switched-mode
power supply for a halogen lamp, commonly known as an electronic transformer, is a clever and simple device which can be enhanced with dimming control |

Four Channel Dimmer Rack: (circuit / schematic design added 6/06) |
|
Halogen Light Dimmer Provides Infinite Control: 03/16/00 EDN-Design Ideas / (added 1/06) Modern lighting systems use halogen
lamps, most of which run on 12V ac from a transformer. The dimmer circuit in Figure 1 can change the intensity of the light from zero to maximum. The dimmer operates at approximately 12V, unlike
the usual ones that function by adjusting the firing angle of the 110 or 220V mains supply.... |

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 6/06) |
