1 Introduction to Connected Lighting with PoE James Crowther

2 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.

3 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

4 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

5 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

7 Complexity Behind the building envelope Traditional Way: Each system has its own usage limitation Numerous interfaces without real synergy End devices spread across the building Duplication of information Maintenance schedule constant learnings for the facility manager

8 Ease of Integration Enables routing of relevant information between subsystems One synchronized performance & status reports One infrastructure accessible by multiple tenants Data Analytics. Source: BPG Properties LTD

9 How is connected lighting different from conventional controls? Basic energy incandescent, efficiency fluorescent or Basic single comfort channel and LED visibility luminaire of spaces Basic Local, task analog support switches and dimmers Compliance Basic sensors with energy efficiency codes E.g. 0-10V / regulations / incentives Devices share no operational data No path to beyond illumination capabilities Enhanced Intelligent energy LED luminaires efficiency with digital Enhanced dimming comfort Enhanced Color changing, task support tunable white, spectrally tunable Transformation of spaces Smart sensors Dynamic atmosphere and ambience for Networked, enhanced digital experiences and mesh control systems E.g. DALI 80% Intelligent, energy savings connected lighting LED luminaires alone over and sensors traditional lighting Maximum comfort and task support Lighting management software Gathers platformand stores intelligence on system status and operations Remote / cloud-based control Data-driven insights E.g. Power over Ethernet (PoE) Serves as platform for location-based services and in-context information Integrated / comprehensive Devices resource share management operational data making it part of the IoT trend Beyond illumination capabilities 80% deployed or available to be deployed Decreases TCO Increases TVO Delivers value beyond illumination

11 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

12 What is PoE? STANDARD Source Voltage REMARKS IEEE 802.3af using data pairs IEEE 802.3af using spare pairs IEEE 802.3bt using all 4 pairs 48 V DC, protected 48 V DC, protected 48 V DC, protected RX, DC+ RX, DC+ TX, DCspare spare TX, DCspare spare RX RX TX DC+ DC+ TX DC- DC- TX, RX, DC+ TX, RX, DC+ TX, RX, DC- TX, RX, DC+ TX, RX, DC+ TX, RX, DC- TX, RX, DC- TX, RX, DC- Industry Standard for embedded PoE Industry Standard for embedded PoE Similar to Cisco UPoE 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. PoE/POE+ Architectures UPoE Architectures Source: Cisco

13 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

14 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

15 How do we do it? How it all connects Complimentary solutions Dynalite (Hybrid) BMS Interface To Envision Manager Server lighting Luminaire with sensor PoE switch Gateway Router Interfaces (APIs) Personal control device Location Functional infrastructure Analytics and optimization

16 How is lighting delivering additional value with IoT Green buildings Connectivity Health and wellbeing Activity based workspaces How Up to 80% energy efficiency over traditional lighting. Easy monitoring and management of lighting system enables for further savings Enables data-driven building management, which in turn, may increase operational budget predictability Can help to increase focus, engagement and employee productivity, reduce absenteeism and employee turnover Support a flexible and modern work environment. Can accommodate different activities in the same space, and support a mobile workforce, hot desking and hoteling Application Energy reporting through software eliminates the need for electricity sub-meters or manual readings, a requirement for LEED v4 certification Use of real time and historical occupancy data for better space utilization with potential savings on rental space Being able to mimic the natural cycle of daylight with electric light in your indoor environments. This supports wakefulness and greater wellbeing With third party app integration, find the nearest available desk or meeting room With tunable white transform a meeting room to support either a focused activity or brainstorming sessions
