Dimmer
Circuit for Normal Light Bulbs : |
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. |

Dome Lamp
Dimmer: Efficiently dim the cars dome or map light (low
voltage light), PDF file |
Dome Light Dimmer for Cars : 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. |

Light Dimmer Circuit With 0 to 10 Volt Input: This is a
simple dimmer circuit that can be controlled with0 -10 VDC. It
is designed for110-Volt AC. |
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. |
Microcontroller MultiChannel Light Dimmer: The project is a
microprocessor-controlled multiple channel lighting dimmer, that
could be used in theatrical and other applications. The device
will accept input from a wide range of interfaces: RS232 input,
DMX512 (theatrical lighting standard) or RS485, or a Musical
Instrument Digital Interface (MIDI). The device will control a
number of lamps by using some form of AC power control. The
firmware in the microcontroller will handle all functions, from
decoding the protocol on either of the input interfaces through
to Timing the firing of power triacs for the output.
