1 Advanced Techniques for Wireless Control and Monitoring of LED Lighting Strategies in Light Europe 2014 Conference Technology Track/Session 4 - Wireless Connectivity/Smart Lighting By Yariv Oren, CEO at Virtual Extension, A Wireless Networks Company

2 Agenda Introduction The Lighting Market Lighting Control and Protocols Adding wireless –why –where –challenges –what’s available Examples Summary 2

3 General lighting market size 3 SOURCE: McKinsey’s 2012 Global Lighting Market Model

4 Key Market Trends for Lighting and Controls Drivers –The need for energy savings, and short & easy payback benefits –Increasing legislation, efficiency standards and government funds –End-user demand for more technological advances and interoperable and open systems –The capability of LED to deliver cheaper, lower power and higher controllable light Restrains –Sluggish economy limits capital and discretionary spending –LED (and other lower cost light sources such as CFL) diminish the ROI 4 SOURCEs: Various analysts

5 Lighting Control market size 5 SOURCE: McKinsey’s 2012 Global Lighting Market Model (compared to ~4.5 for general lighting)

6 Protocols for Lighting Control DALI – the main protocol in use >64 % from al controllable lighting in Europe Standard IEC 62386, new v2 –Other protocols (KNX, DMX, 1-10V/0-10V) –Proprietary Protocols 6 SOURCE: ZVEI statistics (end 2012) & P van der Kolk & K McCann

7 Adding Wireless to Lighting Control Wireless has unique features - compared to wiring –flexibility in deployment, such as in areas difficult to wire –easy to move lamps after deployment –easy to expand deployments Flexibility and Easy translates in faster deployment and lower cost (labour, re-paint materials, etc.) –The total cost of wireless deployment can be lower than of wiring – check it before making a decision Hybrid networks wired–wireless are possible – again, check it before making a decision Advanced modern wireless technologies that are very reliable and cost-effective 7

8 When to use Wireless The main wireless use is for Retrofit: –usually, the main Retrofit projects scope is to replace the older lighting technologies with LED –lighting control is usually added as a secondary scope –wireless can then enable lighting control without the extra cost of wiring or rewiring the site In new deployments –wireless enables lighting control in special locations, such as old buildings, where not allowed or difficult to make holes 8

9 Are Retrofits important? 9 From NAVIGANT’s August 30, 2013 “Intelligent Lighting Controls for Commercial Buildings” market study: … retrofits will make up more than half of the market… (some consider them negligible)

10 Wireless for Lighting - Main Challenges Ease of handling –deployment & maintenance (no skilled personnel) –changes - add luminaries and overcome interference without stoppages and without bringing the network down Scalability - quickly and easily increase size of the network, even by many orders of magnitude Robustness – to wireless interferences and obstructions Coexistence of several networks in same area or overlapping Low power consumption (in particular in modern LED lighting) Low and consistent latency for unicast and broadcast –also for indistinguishable disparity between wired and wireless elements (for On/Off and dimming) especially in broadcasting Bi-directional, to enable both control and monitoring 10

11 Wireless Technologies 11 Routing The legacy approach, calculates and uses routing tables for passing the data Synchronized Flooding Uses all the available routes between the nodes Mesh is the most advanced topology today Peer to Peer Line Bus Star Tree Mesh

12 Putting it all together Lighting Control protocol –choose between: DALI - or non-DALI in Europe DALI is a common choice, especially in commercial indoor good variety of devices – LED luminaries, controllers, presence sensors, etc. trend of DALI luminaires use in outdoor as well Wireless network –choose between the various available technologies simpler protocols and standards in low-end consumer lighting proprietary technologies in commercial and outdoor –hybrid deployments of wired + wireless –PLC phasing out, very few exceptions Cloud based control –particularly in large scale deployments 12

13 DALI Hybrid Wired + Wireless - Example 13 1.The Wireless extension to DALI includes a Wireless Gateway and one or more Bridge Nodes 2.The Bridge Node in the E. room drives a full DALI bus with DALI sensor and luminaires, while the Bridge Nodes on the N. walls and of the standing lamps drive each one DALI luminaire 3.The Wireless extension to DALI mimics the behavior of a wired DALI; the DALI controller (in the W. room) does not distinguish between the W. room wired connection and the wireless network 4.As in any DALI installation, the DALI controllers can be of 2 or more buses, and also can be stacked, for driving more devices than the DALI limitation of 64 address 5.This configuration is relevant mainly for indoor and emergency – commercial deployments Note: this is a proven example, which has been tested with various types of controllers and luminaries, such as from GE, Helvar, Lutron, Mackwell, OMS, OSRAM, Philips Lighting and Tridonic

14 DALI + Internet + Wireless - Example 14 Configuration relevant for all types of commercial deployments – outdoor (including street lighting), indoor and emergency

15 Summary LED retrofits and new deployments should consider the use of wireless or hybrid wire- wireless solutions for faster and lower cost deployment Increase use of DALI in commercial and outdoor deployments, with a large variety of excellent DALI devices and wireless solution available For large centralized deployments, consider cloud management; there, the integration with DALI and wireless offer the best of all worlds. 15
