Overview
The world of wireless lighting control
has seen a dramatic shift from custom
or proprietary lighting solution as
efficient and low cost solutions have
been introduced to the general market.
Consumers recognize the value of
convenience, security, and comfort
that wireless devices bring to the home
or office. The barrier to these systems
in the past has been that most product
manufacturers do not provide a system
that allows interoperability among
different lighting control vendors.
Designers can create an easy to use
lighting control solution using ZigBee
light link (ZLL) profile on the Texas
Instruments Z-Stack Pro platform.
ZLL is designed to run on the CC2530
product family. ZLL was created to
save time, money and installation
frustration by providing a simple easy
to install network of lights, switches,
occupancy sensors, daylight sensors
that can be controlled by a mobile
device such as an tablet and mobile
phone as illustrated in Figure 1.

What makes ZigBee Light Link
valuable?
Lighting control requires low cost
technology, long battery life capability,
reliable network performance and
system security. This is why the ZigBee
Light Link solution is based on ZigBee
technology.

ZigBee Light Link
How does TI ZigBee Light Link
work?
With Light Link, adding or removing
lamps is very easy and robust.
Contrary to other networking solutions,
it does not matter which lamp is
installed first, or whether other lamps
in the network are switched on or off.
With ZigBee Light Link, adding a new
lamp at a remote location is as easy as
adding a lamp nearby in range.
Figure 2 demonstrates the solution.
Only TI can provide you with one stop
shopping for your wireless lighting
projects. Smart phones, tablets and
PCs via bridging devices can control
lighting products based on TI. Wireless
control is possible via direct control
such as the key fob, remote control
and wireless wall switch or occupancy
sensor. ZigBee Light Link can also
be controlled remotely using a tablet
mobile app via a Wi-Fi to ZigBee
gateway. Added digital functionality
can add wake up features or time
phased multi room on/off lighting for
vacation mode security.
