to disseminate the information via an AT&T
wireless network to a GE cloud computing
system, which can help the city figure out how
to improve traffic activities and pollution. It
also helps operate the lights more efficiently
and even provide weather alerts.
GE’s cloud, called Predix, gathers, analyzes, and helps act on data collected from
across GE’s many industrial products and
activities. As part of its new subcontracting
arrangement, GE has given AT&T exclusive
rights to distribute GE’s Intel-based CityIQ
sensor nodes in the US and Mexico.
Current and AT&T are also working
together on a smart city installation in San
Diego, where Current is the lead contractor
in an alliance forged before Current decided
to shift to a subcontracting strategy and its
exclusive reselling through AT&T. ◀
Intense demonstrates LED
downlight with liquid-crystal lens
At LEDucation in late March, one interesting new development was a downlight
from Intense Lighting, a Leviton Company.
The SSL fixture uses a liquid-crystal lens
that enables a dynamic beam spread
adjustable from 12° to 50° with no moving
parts in the luminaire.
Intense has not formally announced the
new product that will be part of the MX fam-
ily. Other products in the MX family have
featured field-replaceable optics that enable
similar changes in beam spread to the liq-
uid-crystal-based design. But the ability to
remotely change the spread with no motor
driving a lens is unique.
Applications such as retail will be a sure
fit for the new product. Changes in a retail
store floor space regularly require adjustment of the accent lighting. Typically, such
changes require ladders or lifts in the space
and a significant disruption of business. In
some instances, the liquid crystal approach
will eliminate that challenge.
The Intense product marks something
of a coming-out party for LensVector, a
startup company based in San Jose, CA in
the heart of Silicon Valley. The company is
focused on the liquid-crystal technology in
which an electrical field is used to change
the orientation of liquid-crystal molecules,
essentially enabling infinity to macro-lens
powers. LensVector supplies lighting manufacturers with the lenses, the power-con-trol architecture needed to drive the lens,
and the software apps for remote control. ◀
