Digital Dimming DALI Ballast for 32w/T8 110V Input - This reference design is a high efficiency, high power factor, 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 IR21592. The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI).  (added 6/06)

Digital Dimming DALI Ballast for 36w/T8 220V Input - This reference design is a high efficiency, high power factor, 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 IR21592. The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI).  (added 6/06)

Digitally Addressable DALI Dimming Ballast - A digitally addressable digital dimming ballast has been developed. It conforms to DALI standard requiring very few parts and operates at very low power. Applications include building management or studio lighting where it is desired to control single or groups of lamps for conserving energy(circuit / schematic design added 6/06)

Digitally control room light intensity - 11/11/04 EDN-Design Ideas: Many people favor different light and temperature settings for different rooms depending upon their mood or whether they are working or relaxing. The circuit in Figure 1 controls the intensity of the artificial light in a room and monitors the temperature of two zones. The two main circuit blocks are the PIC16C67 master controller and the ADT7516 temperature-sensor interface, which includes a.....(design idea added 11/04)

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)

Dimmer/Motor Speed Control - Lamp dimmers using traics can be quite simple,  nothing more than a potentiometer, resistor, capacitor and triac with a built-in diac. (See Teccor's application note for examples and other technical data.) The circuit below is similar....(electronic circuit added 7/03)

Dimming AC Incandescent Lamps using a PIC10F200 - Microchip Application Note Published 22-Nov-05  (app note added 2/06)

Dimming DALI Ballast for 32w/T8 110V Input - This reference design is a high efficiency, high power factor, 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 IR21592. The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI).  (added 6/06)

The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI).  (added 6/06)

Dome Lamp Dimmer - 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….(electronic circuit added 7/03)

Dome light dimmer for Cars - ….(electronic schematic added 03/08)

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: (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.....(design idea added 5/02)

Experimental Cross Fader - ideas to modify simple rotary light dimmers to make a cross-fader (added 4/02)

Four Channel Dimmer Rack - (circuit / schematic design added 6/06)

Halogen Light Dimmer Provides Infinite Control - 03/16/00 EDN-Design Ideas: 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.....(design idea added 1/06)

High Efficiency Halogen Bike Light Dimmer - This circuit uses a PIC16F84 microcontroller with some software to control20-Watt12V DC halogen lamp (added 7/03)

High Power Desktop LCD Backlight Controller Supports Wide Dimming Ratios While Maximizing Lamp Lifetime - DN264  Design Notes (Linear Technology) (app note added 6/06)

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 6/06)

IR21592 Dimming Ballast Control IC Design Kit - The IRPLDIM1E 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.  (added 6/06)
