3 types of light controller Fully integrated electronic ballast Semi integrated electronic ballast Lamp controller

Fully integrated electronic ballast Features: All in one box; Control: dimming, on/off etc; Monitoring: high/low voltage & current, high temperature, life/running hour, capacitor failure etc. Measuring: energy consumption, power factor, voltage, current, light level etc; Configuring/calibrating: power, warm-up time, running hour, energy etc. Installation: pre-installed in the light fixture on the top side Providers: Rongwen of China, Hongyuan of China, etc.

Fully integrated electronic ballast in the top side fixture HPS tube Compensation capacitor Magnetic ballast top side fixture in the top side fixture Fully integrated electronic ballast pole

Fully integrated electronic ballast Pros: The best energy saving Highest performance of power to active power; Dimming control Cons: The highest cost Brand new light fixture A ballast per light The longest installation time Up to the number of lifts

Semi integrated electronic ballast Features: All in one box, but the magnetic ballast; Control: dimming, on/off etc; Monitoring: high/low voltage & current, high temperature, life/running hour, capacitor failure etc. Measuring: energy consumption, power factor, voltage, current, light level etc; Configuring/calibrating: power, warm-up time, running hour, energy etc; Installation: in the down side box of poles and need to move the compensation capacitor in the light fixture to the down side box Providers: Balliance of China, Vstar of China, etc.

Semi integrated electronic ballast in the top side fixture HPS tube Compensation capacitor Magnetic ballast top side fixture down side box in the down side box in the top side fixture pole Semi integrated electronic ballast

Semi integrated electronic ballast Pros: The better energy saving Dimming control; Cons: The higher cost A ballast per light The longer installation time Up to the number of lifts

Lamp controller Features: All in one box, but the magnetic ballast; Control: 4 relay outputs for direct switching on/off 4 lamps Monitoring: high/low voltage & current, high temperature, life/running hour, capacitor failure etc. Measuring: energy consumption, power factor, voltage, current, light level etc; Configuring/calibrating: power, warm-up time, running hour, energy etc. Installation: in the down side box of poles Providers: Telchina of China, etc.

Compensation capacitor Lamp controller in the top side fixture HPS tube Compensation capacitor Magnetic ballast top side fixture down side box in the down side box in the top side fixture pole Lamp controller

Lamp controller Pros: The better energy saving Cons: The least cost Just simple ON/OFF control; Cons: The least cost A ballast per pole The shortest installation time Up to the number of workers

Lamp Controller Usage Very suitable for 2 or more arms or more than 1 lamps per pole for energy saving and maintenance. Lamp1 Lamp2 Arm1 Arm2

i.LON SmartServer - Segment Controller Local Master Controller Bridge to Data Networks Built-in Astronomical clock & Real-time clock for schedulers Built-in data logging for data collection Built-in alarming for real time alarm notification Built-in I/O for door of cabinet and power main switch monitoring and control MODBUS extensions for segment energy measurement RS232 extensions for RTU Power line Interface with signal repeating Integrated serial ports for connectivity to GPRS modems (VPN) Real time collection using SOAP/XML protocol Remote Commissioning, Troubleshooting & Upgrades No on-site system services required post installation

Back office Real time control by lamp, by pole, by group, by mode Real time monitoring: voltage, current, temperature Alarm dispatch Energy analysis: energy data collect and report Maintenance planning

Application: Full on mode (holiday)

Application: Decoration off mode (normal)

Application: Side every other off mode (late at night)

Application: Side off mode (midnight)

Savings through simple on/off Switch off decoration lights Dim down or switch off lights by the schdeluer Virtual power per pole

Virtual power per pole With off or dimming, it is possible to virtually have step power per pole

Too high matchs 30m

Switch off every other light 30m

Improved maintenance With feedback of information it is possible to have: Improved group replacement Improved spot replacement Guarantees management

Guaranties It is possible to have precise information about burning hours Know if lamp failure is within guaranty period Ask for payback if lamp lasted less than expected

Summary of financial benefits Energy saving due to simple switching on/off up to 45% Maintenance savings up to 50%

Non financial benefits Green issue Less light pollution Energy saving Less toxic lamp wastes Others More accurate forecasts and planning Saved maintenance time

Value added Anti cable theft Leverage the smart network to prevent the power cable from stealing with adding nodes of Anti cable theft Can reduce the cost and keep safety
