Introduction to Connected Lighting with PoE James Crowther
Course Description The lighting industry is going through a fundamental change with the transition to LED-based, digital lighting. Technologies such as PoE which were originally intended for low power digital devices can now find use cases for lighting applications due to the low power demand of the LEDs. PoE technology can enable a lighting system to be truly connected because it is based on a standard that is widely accepted in the IT world. Such a commonality between the lighting infrastructure and the IT infrastructure can help to bridge gaps traditionally seen in a building wide system integration. In a connected system, the lighting infrastructure plays the lead in providing quality illumination and collecting data (via sensors) which can be accessed and channelled through various IT platforms for data mining.
Learning Objective Understand what makes a lighting system connected Learn the basics of PoE technology and its history Understand why PoE technology is being packaged into a lighting offering Learn the differences between PoE and traditional lighting controls protocols Gather some of the industry trends and execution of PoE for lighting Overview of PoE lighting commercial projects Deloitte, Clemson University, Cisco
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. Analytics Building Operations Controls
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 Sense Anticipate Respond

What is PoE? Source: DSP Design 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

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. PoE/POE+ Architectures UPoE Architectures Source: Cisco
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
