Introduction to Connected Lighting with PoE

James Crowther

Course Description

• The lighting industry is going through a fundamental change with the transitionto LED-based, digital lighting. Technologies such as PoE which were originallyintended for low power digital devices can now find use cases for lightingapplications due to the low power demand of the LEDs.

• PoE technology can enable a lighting system to be truly connected because it isbased on a standard that is widely accepted in the IT world. Such a commonalitybetween the lighting infrastructure and the IT infrastructure can help to bridgegaps traditionally seen in a building wide system integration. In a connectedsystem, the lighting infrastructure plays the lead in providing quality illuminationand collecting data (via sensors) which can be accessed and channelled throughvarious IT platforms for data mining.

Learning Objective

• Understand what makes a lighting system connected

• Learn the basics of PoE technology and its history

What do we mean by a connected system ?

• System - a set of interdependent components forming an integrated whole and delivering a specific set of capabilities.

• In a connected system various sub systems interface with each other to deliver benefits beyond their functional attributes. • Well being and comfort

• Information gathering

• Infrastructure extension

• Improved experience

• Better Utilization

Connected Lighting

• Lighting is everywhere in the building

• Imagine every lighting fixture with sensors, location beacons, wireless access points, and other intelligent devices . . .• Opportunity to extend the role of a building’s

lighting infrastructure

• Becomes a pathway for information and data

• Enables people to connect — to each other, to the spaces they work and live in and to information that is relevant to them in a particular location.

• Enables various levels of personalization based on preferences

How is connected lighting different from conventional controls?

Increases TVO Delivers value beyond illuminationDecreases TCO

• Devices share no operational data

• No path to beyond illumination capabilities

• Devices share operational data making it part of the IoT trend

• Beyond illumination capabilities deployed or available to be deployed

What is PoE ?

• Power over Ethernet (PoE) is the ability to deliver 48 VDC of power over the same copper cable as Ethernet. Two primary elements are required in order to implement PoE. They are:

• power sourcing equipment (PSE)—the LAN switch or source power delivered over Ethernet

• the powered device (PD)—the end device that accepts and uses power from the Ethernet cable for its operation

Similar to CiscoUPoE

• The original IEEE PoE standard (IEEE 802.3af) provided up to 13-watts and was originally used to power Enterprise IP Phones.

• In 2009, the IEEE standard 802.3at standard was released with the ability to provide up to 25.5 Watts for apps such as Security cameras, access control points, and wireless backhaul systems.

• The IEEE Committee is now developing a new standard (IEEE802.3bt) which will power up 70/90 Watt loads.

Benefits of PoE

• Installation Savings

• Eliminates the need for electrical outlet installation

• Low voltage and uses a single cable for power & data

• Reduces chances of mis-wiring, loose connection etc.

• Less pipe and less wire

• Central Power Management

• Physically connected but software routed

• Devices can be remotely powered down during periods of low usage

• High Bandwidth & High density

• Bidirectional data transmission in real time

• Ease of Integration

• Facility owners and managers can have an integrated view of all devices

• Merge or build upon IT infrastructure

• APIs

• Scalability & Flexibility

PoE based Connected Lighting System

• PoE is not a system by itself !

• The combination of PoE enabled fixtures, various sensors, user interfaces, software etc all coming together to deliver an integrated solution makes it lighting system.

• Fixtures become an “Internet of Everything” device

• Every fixture gets a unique (IP) address

• Every fixture can have embedded sensors

• Individually identified, located, monitored, and controlled

• Future proof

• Security & Privacy• Behind IT’s firewall

• Systems are capable of recognizing presence of people, but not who the person is
