Traffic, environmental, others‌

- Independent of wide-area network choices Implement new services without changing the infrastructure 

10

Electric vehicle smart chargers


Positioning



11

Municipalities and Road Authorities Immense savings in energy consumption Lowest maintenance cost possible Increased safety and security - Make outdoor lighting environmentally friendly Wide choice of interoperable solution providers and components, based on ISO 14908 and SOAP/XML communication standard


Positioning



12

Public Lighting Service Providers Lower maintenance cost - Increased service level Increased customer control - Generate new revenue by providing additional estreet related services


Positioning



13

Luminaires manufacturers - They (re)gain control of their customers by offering a total solution - Shortest time to market - Best way to play in a fast growing new market System based on a reliable ISO standard technology


Main Elements of a Streetlight Network 

Extremely reliable power line light controller - Use existing city electricity wires for power and communications: no new wires needed Standards-based signaling - Many suppliers on the market 



Aditel, Beta, Fulum, Kim, Romlight, SELC, Intron, Seiteco, Philips, etc.

Typical Saving Calculations - Retrofit



Hardware cost:

EkoLum Segment Gateway 速: 

$400 per pole (ballast, fixture etc) $5 per pole (assuming 100 poles/segment)



HMI software:

$2 per pole (assuming 100 poles/segment)



Installation costs:

$50 (depends upon location)



Cost per point:

$457



Total cost:

$45,700,000 (assuming 100k lights)



Energy Saving

$3,000,000 (assuming 60% reduction)*



Maintenance Saving $3,000,000 *(68 million kWh/yr used by 100k lights @ $0,07/kWh)

17


Typical ROI

Return on Investment = 7 years  Energy savings breakdown - Control: ~40% – Modern optics: ~20% - Modern lamps: ~10% 



18

Other benefits not included: - Reduction in Carbon foot print: 25,000 metric ton CO2/year - Safety and Security on city streets - City beautification


Financing models  Self-financed

- City pays for the system and receives direct benefits  Bank loan - Bank finances the system for the city and recover the investment with interests 

19

Service provider-financed - Service provider pays for the system - City keeps paying the SP what was paying before (energy and maintenance) - SP recovers the investment from savings in energy and maintenance

Voltage, Current, Ballast Temperature, etc. Consumed energy (calculated) 



23

Standard Protocol for Communication Utilizes ISO 14908-2 global standard - Bidirectional real-time communication




Most Common Types of Lamp 

Mercury Vapor - Very common - Being replaced because of poor energy efficiency



HPS and MH - Second most efficient and are - Currently being used to replace MV lamps Standard for traditional new installations and replacements - Poor CRI



LPS - Most efficient - Very poor color rendering



LED - Great CRI - Higher life span Decreasing costs Improving efficiency Improving lenses/optics - More favourable power reduction normative

24


Lamp Replacement Strategy 

Typically mercury vapor lamps are used for street lighting and other outdoor lighting (car parks, etc)



Lamps are bring replaced with energy efficient lamp High Intensity Discharge (HID) as follows: - For Street Lighting 

High Pressure Sodium - 200 to 400 W (Orange-White color Light)

- For Warehouses, Outdoor & Parking Lots 

Metal Halides - 100 to 250 W (Natural White color Light)

- Some cities (e.g. San Jose, CA) use 

For Street Lights - Low Pressure Sodium - 180 W (Yellow Light)

25


Types of Ballasts & PL Controller



EMEA - 230V, 35W to 100W - Interface to ballst: serial, 1 to 10V, Dali, Madli, native PL



US/Canada - 120V, 200W to 400W

- Interface: serial, 1 to 10V, Madli, native PL  Asia - 120 to 240 V - Interface = 1 to 10V, native PL 26
