Adaptive Wireless Lighting Control Systems Lighting Control

ETCC Presentation Mark Keating

Lumewave • 2.5 Years - Young • Developed core technology for our centrally

managed, wireless lighting control system specifically designed for outdoor fixture control – Co-developed, tested and patented predictive

direction of travel (DOT) based pathway lighting control process with CLTC, UC-Davis

• Packaged technology for installation on the exterior or interior of fixture or pole

• Completed installing the largest adaptive (DOT) pathway control system: – UC-Davis

• Over 1,000 fixtures on pathways alone

Design Criteria – Be Simple!

• Simple to Install

• Simple to commission

• Simple to operate

• Simple to maintain

Target Applications

• Campuses – Schools/Universities – Corporate – Military

• Types of Fixtures – Any dimmable technology:

• LED, Induction, Plasma, eHID

• Adaptive Control Applications – Pathways, Wall-Packs, Post-Tops – Streetlights based on pedestrian and automobile

traffic and time of day per RP-8 5

The Wireless Side of Things

• IEEE 802.15.4 • 900Mhz (902 – 928Mhz)

– High power/Long Range (250mw/24DBM) • AES Encryption • Point to Point / Point to Multi-Point

– Base stations (one gateway) with repeaters to extend coverage

– Any controller may be a repeater

– Multiple gateways for larger area coverage

Adaptive Exterior Lighting Control

• Adaptive control based on combinations of time, sensor input, light levels, etc.

• Applications: – Pathways – Area – Building Exterior – Parking lots – Can also work with streetlights using new

vehicle and pedestrian sensor technology • Test project about to start with SCE (Eagle Glen)

Adaptive Direction of Travel Control

9

Direction Of Travel Control

• At dusk, lights come on at 20% lumen output • When motion is detected by each fixture, others

are told about it and react as programmed – Fixtures in advance and behind the sensed direction

of travel are raise level to 100%. After a fixed time and mo pedestrians have been detected on the pathway, the light level reduces again to the 20%

• Requires for this function – Fixture with dimmable driver – Motion sensor – Peer-Peer wireless controller (Lumewave TOP900) – Pathway location ID or GPS Location

Cost reduced by design

UC-Davis Installation

• Wireless controllers installed on or within: – Streetlights (On dusk – dawn, off dawn – dusk) – Pathway Lights - Adaptive – Wall Packs - Adaptive – Post Tops - Adaptive

• All fixtures were replaced with dimmable LED • Additional savings documented from adaptive

control of pathways averages >60%

Adaptive Parking Lot Lighting Control

24

Requires Wide Area Motion Sensing

• To properly control parking lot lighting based on motion, the motion sensing equipment must have long range and wide coverage patterns

• In most cases, poles are spaced 100’+ apart so multiple sensors per/pole may be required to provide overlapping,360 degree coverage

• This can be accomplished.

Adaptive Control Conclusions

• Conclusion form Test Results: – Adaptive control of pathway, area and

building exterior lighting will reduce the energy consumption > 50%

Next Step - Join Up With Smart Grid • Smart-Grid

– IEEE 802.15.4G – ANSI 12.22 file

delivery – Can connect to

existing AMI or, – Can be installed as

stand-alone systems
