of HVAC costs. For every three watts reduced in lighting,
there’s a corresponding one-watt reduction in HVAC load.
Low voltage, smart lighting also provides significant health
and safety benefits, allowing easy maintenance and
office reconfiguration. Advanced emergency evacuation
wayfinding uses LED luminaires to flash and change colour
to aid employees in locating the nearest and safest exit
route.
Powering intelligent lighting systems
The majority of intelligent lighting systems consist of a
centralised LED power system that provides a DC current to
luminaires or sensors installed in the ceiling. There are two
ways of achieving this:
Power over Ethernet (PoE) is a standard that allows both
power and control signals to be transmitted along the same
RJ45 cable to an intelligent light containing an electronic
LED and control interface
Power and Ethernet (PaE) is a system where
manufacturers provide power to LED fixtures from
centralised LED driver units, which may include the ability to
use sensors with RJ45 or other connection methods
PoE systems are commonly used today within buildings
to support VoIP and security CCTV systems, where devices
have low power requirements but aren’t currently being
deployed in lighting installations due to a significant cost
implication as the only high power (>25W) systems available
are proprietary, which limits high volume deployments.
A new, highly cost-effective DC-based solution termed
Power and Ethernet (PaE), offers improved benefits over
standard PoE, without the cost prohibitive PoE endpoints
(similar to LED drivers), while improving overall system
reliability.
There are significant advantages including rapid setup
and programming compared to traditional control systems.
All that’s required is simple low voltage wiring, no need for
specialised electricians, as mains voltages are not prevalent
