For a proof-of-concept project, I need to
simulate daylight for day and year cycles. For this purpose,
incandescent lamps are OK. Specifically, ten 40W bulbs (~3.5 amps
total). They will be off during 'night' and full brightness at 'noon on
June 21' and somwhere in between during other 'daylight' hours. So what
I think I need is a PC controlled dimmer and a program with two loops
one for the day and one for the year.
I searched and
found DMX-512 controlled dimmers used to control stage lighting made by
Leviton and others. Seems like it would work. Also found some info
about rs-232 to DMX-512 conversion and found some manufactured
converters but they are pricey.
I have a Compact Fieldpoint system.
Any
suggestions of a better way to make a software controlled dimmer? Or if
not any guidance regarding the approach outlined above?
Thanks in advance.
Kevin
