System Types

13

• Centralized controllers switch and dim limited groups of luminaires

• Typically handle one branch circuit worth of load

• Zones are based on physical wiring

• These products do not meet the DLC specifications for inclusion in the Qualified Products List

Room-Based

Room-Based Example

15

• Luminaires have on-board controllers for individual addressability

• As a result, these systems can generally handle an unlimited amount of load

• Zones are created in the software and are not based on physical wiring

• These systems do meet DLC specifications for the Qualified Products List

Building/Enterprise

Building/Enterprise

17

Room vs. Building/Enterprise Systems

Room-Based:

• Centralized load controllers

• Zoning based on physical wiring

• Limited lighting load capacity

• May not use all control strategies

• Relatively low-cost and easy to specify and

install

Building/Enterprise:

• Luminaire-integrated load controllers

• Zoning created in software

• Virtually unlimited lighting load capacity

• Typically uses all control strategies

• Relatively higher-cost and may be more complex to

specify and install

Elements of a Control System

18

19

• Contains relay for switching luminaire ON and OFF

• Contains circuitry for sending a dimming signal to the luminaire

Luminaire Controller

20

• Occupancy / vacancy sensors

• Photosensors for daylight harvesting

• Some sensors combine different functions

(i.e., occupancy and photosensing)

Sensors

21

• “Area” switches (for zone ON/OFF)

• Scene selectors

• Other override devices

Switches

22

Distributes network connections from a central server to end nodes (luminaires, sensors, switches)

Gateway

23

• Stores programming, schedules, behavior, control profiles, zoning information and energy use data

• Manages operation of the system including notifications when problems arise

Image courtesy of Enlighted

Server

24

• Create zones/assign equipment to zones

• Create schedules

• Program variables/options for component behavior

• Manage the system

• Display and record energy use

• Check for faults/problems

Software

Specification

26

• Wired Communication: data travels along wires as digital information

• Wireless Communication: data travels through the air as digital information

• Hybrid System: wired/wireless combination

Wired vs. Wireless

27

All devices communicate directly with gateway

May reduce network traffic and increase communication speed

Self-healing mesh network

All devices can talk to each other and to gateways

If a device fails the signal finds an alternate path to the

gateway

Determines how devices talk to each other

Different topologies present unique pros and cons

Some topologies are more common in wired vs.

wireless systems

Luminaires, sensors and switches are connected to gateways or

directly to the server via low-voltage cables

Essentially functions as a wired local area network (LAN)

Topology

28

• Set of rules that define how devices communicate

• Devices designed to same protocol(s) are interoperable

• May be open standard, de facto open standard, or proprietary

Server ⟷ gateways: often uses propriety protocol

Gateways ⟷ components (wireless): often ZigBee or Bluetooth

Gateways ⟷ components (wired): often proprietary, sometimes DALI

Luminaire controllers ⟷ LED drivers: typically 0-10V, sometimes DALI

Protocols

29

• Provisions in building/enterprise-based systems

• Third-party current transducers attached to branch circuits

• Embedded in luminaire-integrated controllers

Measuring Energy Use

30

• Building/enterprise-based systems typically monitor the health of the system

• Continuous check of status of connected devices

• Automatic notification to designated staff about problems that arise

Monitoring

31

• Device not reporting

• Luminaire fault detected

• Communications failure

Common network security methods:

128-bit AES encryption

User names/passwords for authorized operators/users

• UL 2900 certification addresses potential vulnerability

• Connecting a lighting control system’s devices via an existing IT network may cause additional risk of hacking

Security

33

• Building Management System (BMS)

• Automated Demand Response Server (ADR)

• Heating, Ventilation & Air Conditioning (HVAC)

• Security/Life Safety

Integration with Other Systems

34

• Lighting devices used for light, control, and as

sources of lighting and other data

• Remote or luminaire-integrated sensors

• May pass along data to third-party software or other

building systems

• Internet-Ready Alliance Standard: defines physical,

electrical, and communication interface between

luminaires, sensors, systems

• Data, data, data

The Information of Things

Internet of Things (IoT)

35

• Owner Project Requirements

• Basis of Design

• Lighting Controls Narrative

• Evaluate potential vendors

• Select and procure desired system

Deployment Steps

36

• Install system

• Installation verification and functional testing

• Commissioning

• Documentation turnover
