10 Things You Need To Know About Connected Lighting

2

Q1: What is the Internet-of-Things?

A1: It depends who you ask

Kevin Ashton, cofounder and executive director of the Auto-ID Center at MIT, first mentioned the Internet of Things in a presentation he made to Procter & Gamble in 1999. “Today computers -- and, therefore, the Internet -- are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,024 terabytes) of data available on the Internet were first captured and created by human beings by typing, pressing a record button, taking a digital picture or scanning a bar code. The problem is, people have limited time, attention and accuracy -- all of which means they are not very good at capturing data about things in the real world. If we had computers that knew everything there was to know about things -- using data they gathered without any help from us -- we would be able to track and count everything and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling and whether they were fresh or past their best.”

A2: Change the way we go from place to place?

The IoT connects data producers.

The IoT aggregates data sets.

The IoT enables on-demand data access to data consumers.

The IoT enables the consumption of data using standardized means.

You are what you eat. How can, will data be

consumed, and towards what ends?

Q3: What is a Connected Lighting device?

1) Controllable and Intelligent

SSL Source

2) Wired, Wireless Network

Interface(s)

3) Sensor(s) Connected Lighting Device

Connected Lighting Device



A3: It depends who you ask

• Controllable

• Intelligent

• Connected

• Data consumer and producer

• Many permutations

9

Q4: What can a connected lighting device do?

A4) Many possibilities.

One example: Traffic detection (Sensity Systems)

10

Q5: What is a Connected Lighting System?

A5: A data collection platform that also lights spaces Bonus Question: Is this different from traditional lighting control? Answer: Yes

Opportunity Enabling intelligent lighting devices with (the right type and amount of) data can result in reduced energy consumption and improved lighting performance

The collected data may enable other revenue

streams that compete with lighting and energy

performance

Threat




Internet, Cloud

Non-Lighting System

[data]

11

Q6: What can a Connected Lighting System do?

A6) Many possibilities.

One example: Indoor Positioning, (Acuity)

12

Q7: What is driving Connected Lighting?

A7a: Solid-State Lighting

A7b: Significant technology trends driving performance improvements and cost reductions

A7c: Emergence of cloud storage, computing, analytics

A7d: Focus on systems and data

Computing

Mobile

Intelligence (i.e. microcontrollers),

Network interfaces

Sensors

13

Q8 Compatibility, Interoperability, Interchangeability?

A8a) Compatibility: The ability of two or more devices, applications, networks, or systems to coexist in the same physical environment – that is, operate without corrupting, interfering with, or hindering the operation of the other entity.

A8b: Interoperability: The ability of two or more devices, applications, networks, or systems to work together, and (more specifically) to reliably and securely exchange and

readily use data with a common shared meaning.

A8c: Interchangeability: The ability of two or more devices, applications, networks, or systems to be physically exchanged for each other and provide a defined level of identical operation without additional configuration.

14

Q8 Compatibility, Interoperability, Interchangeability?

Compatibility

Interchangeability

Interoperability

15

Q9: What is PoE?

A9 PoE = Power over Ethernet – Combined power and data – Low voltage distribution – Established, standardized for other applications (e.g. phones, access points) – Potentially lower installation, configuration, maintenance costs

Bonus question: low voltage DC systems can have significant energy losses due to voltage drop. Is this a problem? Answer: Can be, but mitigated by larger gauge conductors, limited run lengths, distributed switches, system design

16

Q10: What is LiFi?

A10 LiFi (1) = technology alternative to WiFi

– Use of visible light electromagnetic spectrum (instead of radio frequency) to enable high-speed wireless data communication and internet access

– Greater security, safety and data densities

– Potentially reduced infrastructure complexity and energy consumption

A10 LiFi (2) = technology alternative to GPS, for indoor positioning

17

Bonus: Will “open standards” make this all happen?

Answer: Yes, eventually

Open does not guarantee adoption, or interoperability

Mature Standard

1) Goal definition

2) Specification

3) Specification Verification

4) Broad Manufacturer

Adoption

5) Compliance Testing Program

6) Standardization

7) Broad Market Adoption

multiple

iterations

18

Bonus: Will Connected Lighting save or use more energy?

Answer: Yes

Intelligence + Data = Improved performance (lighting, energy, space utilization…)

Intelligence, Data Creation, Data Exchange consume energy

Goal: Energy reporting data driven energy management

19

Data driven energy management

Discovery & Measurement

Asset data, Remote

monitoring
