Smart lighting: a bright idea whose time has come
Using JenNet-IP helps address many of the issues associated with traditional networks. It
provides redundancy by using a self-healing mechanism that automatically finds a new
route if the radio connection between two nodes is broken. It reshapes the network to
minimize the number of hops, thus minimizing latency. On top of that it can be scaled to
include hundreds of nodes.
The JenNet-IP network can be controlled in a standalone mode, using a wireless
(capacitive touch) remote control or wall switches. With the addition of a low-cost gateway,
any IP-equipped device, such as a smartphone, tablet, PC or Internet-enabled TV can
control the network. The gateway function also enables easy integration with commercial
and industrial systems for building management. An option for over-the-network
downloads provides a user-friendly environment for upgrading application code and
firmware, so the solution can evolve over time.
Running the JenNet-IP layer means that the GreenChip platform provides the lowest cost,
lowest latency, and most widely compatible solution. The layer supports other popular
standards, including ZigBee, and contributes to the overall power efficiency of the
solution.
4. Summary
As incandescent bulbs are being phased out around the world, more energy-efficient
bulbs, such as CFLs and SSLs, have become the new standard for lighting. Driver ICs
that improve power conversion and extend bulb lifetimes have already done a lot to save
energy in these new bulbs. Now, by combining the driver technology with wireless IP
connectivity, it is possible to create smart lighting networks that save even more. Bulbs
can be turned on, turned off, and dimmed by using digital commands sent wirelessly from
any computer, smartphone, or tablet. Lighting can also be controlled automatically by
using network-based sensors that monitor room occupancy or light levels.
NXP Semiconductors has developed the GreenChip chip set, which makes smart lighting
a reality. The GreenChip platform enables multiple control options, including RF remote
control, battery-powered switches, and control via IP-enabled sensors. The platform
includes several features that minimize power consumption. It offers networking features
that improve reliability, support easy extension, and enable quick integration with
commercial and industrial building-management systems.
