ekolum : smart street lighting software
DESCRIPTION
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.TRANSCRIPT

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

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)

� 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 installedon 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!
