cost of smart lighting. But Costello said the
energy pitch upfront won’t work.
Back to the subtitle of the talk, Costello
sees the danger as non-connected and sen-sor-less LED lighting being installed with a
likely lifetime in the 15-year range. He said,
“You are condemning these buildings to not
have an IoT framework.” Building owners
and facility managers will not be open to
again retrofitting that space with Io T capabilities for more than a decade.
Of course, SSL will succeed in many more
applications outside of general lighting with
some already being penetrated, but with a
much larger potential in the future. Consider
disinfection in facilities from medical to athletic to daycare. Colleen Costello, president
and co-founder of Vital Vio, presented the
concept of lighting products that both produce functional illumination and disinfect
a space continuously (Fig. 6).
We have written previously about how
ultraviolet (UV) energy can sanitize a surface
or water instantaneously. In fact, that con-
cept was presented at SIL several years back
( http://bit.ly/1k Xzh1e). But UV light can’t be
safely used in an open building space where
humans are present.
Vital Vio is using violet light that is not
dangerous to the human eye and is below the
wavelengths associated with a blue-light haz-
ard for humans. But the pathogen-killing phe-
nomenon is quite different from that associ-
ated with UV. Costello said the technology
targets specific molecules in bacteria cells and
delivers an overload of oxygen that explodes
the cells. But such sanitation takes time.
The Vital Vio approach is centered on
FIG. 5. Joe Costello of Enlighted warned that installing SSL without intelligent sensors
today may push back the evolution of smart buildings for a decade.
