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 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) |

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

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) |
