Currently, there are several
laboratory prototype LED porch light fixtures that represent
the current state of the technologies to be developed
within this project. These prototypes involve LED arrays
integrated with occupancy sensors and will serve as
a launching point for this project's research activities.
Also,
the vast majority of residential porch lights employ
incandescent light sources. A small but increasing fraction
of porch lights utilize screw-based compact fluorescent
lamps (CFLs). Porch lights that utilize motion detectors
and/or light sensors are uncommon (exterior luminaires
that utilize motion detectors and light sensors are
more commonly security lights).
A
significant
niche market exists for porch lights that utilize yellow
"bug lights." This is of interest for this project as
the color of these lamps is not substantially different
than that of amber LEDs. Amber LEDs are some of the
cheapest, brightest and most efficient of the LEDs that
are currently on the market.
