EkoLum is a remote control system for Street Lighting installations that provides an efficient diagnosis of the current state of each luminaire. Based on a point-to-point control architecture, the system reports in real time the alarms coming from the luminaires and allows the remote switching on/off and the dimming of the lamps.

24. 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

25. 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)

45. EkoLum Segment Gateway simplifies Installation
Main challenge
- Installation needs to be done by electricians with no LonWorks
skills
- Many devices of the same type (e.g. lamps) need to be installed
on the correct location
- Changing damaged devices needs to be simple - System
functionality and reliability needs to be checked easily and fast
Installation time is money!
